How does the head of the purification swab join with the rod? The common purification swabs in our days are made of cotton, and the purification swabs we will mention here are basically used in industrial production. We all know that cotton is directly wound on the rod, so how is the industrial purification swab joined? Kangfutai medical equipment tells you the following ways! The first one is to stick the head of the purification swab directly onto the rod Some manufacturers will use glue, some manufacturers will use other sticky materials, the result is as long as the head stick up, to ensure that it will not fall on the line. Although this kind of manufacturing process is very convenient to produce, it can't be used at all when it is used in industry. Because they will have some residues on them, which will cause the residues to fall onto the products, forming secondary pollution and poor cleaning effect. The second is the principle of hot sealing First, use hot air to press the head of the purification swab, and our purification swab is using this manufacturing process. Because hot air can blow off part of the original dust on the cotton swab, and the head of the cotton swab is more closely connected with the rod of the cotton swab, leaving no residue, the cleaning effect is good. Longer time to use! Third: the use of ultrasonic production The principle is that the high frequency oscillation wave is transmitted to the surface of two objects to be welded. Under the condition of pressure, the surface of two objects collides with each other to form the fusion between molecular layers. Although the quality o

What are the advantages of cleaning cotton swabs ? The clean cotton swabs are also called dust-free wipe sticks, dust-free cotton swabs, which are produced and processed in the cleaner workshop with high-definition cleanliness. The biggest difference between clean cotton swabs and general cotton swabs is as follows: material, function and advantage. Material: the dust-free cleaning cotton swabs / wipe rods are divided into sponge head and cloth head. They are treated without dust and packed in a clean room. Because the wiping consumables used in high-level dust-free environment must reach more than 100, only dust-free cotton swabs can meet the requirements. They are mainly used for HDD, PCB, FPD, lens, semiconductor and other work to wipe the attachment, dust dust wait. Advantages: a: Knitted nylon (super wear-resistant) b: Knitting superfine fiber (wipe fine dust, wear resistance is general) c: Woven microfiber (professional for fiber wipe) d: Knitted polyester (the fabric surface is longitudinal, with deep gap, which can accommodate more dirt) E: non woven cloth head (low grade, but relatively small processing difficulty and low price) The above dust-free cotton swabs can be used in 100 grade clean room, suitable for electronic use. Sponge head cotton swabs can have the following two types according to the density and chip removal condition of sponge: 1: Open hole Pu sponge, 100ppi (PPI -- port per inch, refers to the number of holes per inch, the more the number, the more delicate the sponge, it is also less simple to remove the debris). The spong

What are the precautions for the purchase of antistatic cotton swabs? Anti static cotton swab is a kind of dust-free scrubbing products, which is specially designed for highly clean and anti-static environment. Polyurethane sponge, continuous filament polyester fiber and ultra-fine fiber are used as raw materials for the head of swab, and the swab is treated in the 10 grade (iso4 grade) purification room to ensure the ultra-low ion content and non evaporative residual content of swab (without silicon, ammonia and dioctyl phthalate DOP), And the occurrence of ultra-low particles; the selection of conductive thin shaft can effectively reduce and control its resistance value, conflict voltage, decay time and other ESD parameters, and the perfect edge sealing technology can make the head successfully fixed on the shaft handle, which can effectively prevent the harm of static electricity to the product in the process of application, and also prevent the pollution caused by the use of adhesive. Key points for purchasing antistatic cotton swabs: From the perspective of cost: after confirming the application orientation of cotton swabs, users need to select the handle with appropriate length and width according to the practical requirements. They need to confirm whether the cotton swab head needs to be double headed, and then confirm the size and shape of the cotton swab head. Secondly, they need to fully understand the quality and application function of each raw material and the packaging required. Generally speaking, double headed cotton swabs are more expensive, and the more complex the shape, the more expensive, such as Sharp and spiral head, anti-static function and purification to the better, the price will be slightly higher. Users

How to choose a mask ? Duration of application From the point of view of human physiological structure, because people's nasal mucosa blood circulation is very strong, the passage in the nasal cavity is very tortuous, and the nasal hair constructs a "barrier" of filtration. When the air is inhaled into the nostril, the airflow forms a vortex in the tortuous passage, which heats the airflow in the nasal cavity. Some tests show that when the cold air of minus 7 ℃ is inhaled into the lungs through the nasal cavity, the air flow has been heated to 28.8 ℃, which is very close to the temperature of the human body. If you wear a mask for a long time, it will make the nasal mucosa become fragile and lose the original physiological function of the nasal cavity, so you can't wear a mask for a long time. Masks can only be worn in special environments, such as in places where there are many people and the air does not flow. Of course, it is necessary to wear a mask when walking in the wild, in order to resist the wind, sand and cold, or in the environment with air pollution, but the time should not be too long. In addition, in the flu season, go to public places where there may be many pathogens, you should also wear masks. Wearing a mask is only one of the ways to prevent respiratory infectious diseases. The most important thing is to adhere to outstanding living habits. Cleaning and maintenance The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the exhaled bacteria and saliva. Therefore, the two sides can not be replaced, otherwise the infected dirt in the outer layer will be inhaled into the human body when it is directly close to the face, and be

What are the precautions for masks? Duration of application From the perspective of human physiological structure, because of the strong blood circulation in human nasal mucosa, the channel in the nasal cavity is very curved, and the nasal hair forms a filter "barrier". When air is drawn into the nostril, the air flow forms a vortex in the curved channel, which makes the air flow in the nasal cavity warm. Some tests have shown that when the cold air at minus 7 ℃ is inhaled into the lungs through the nasal cavity, the air flow has been heated to 28.8 ℃, which is very close to the temperature of the human body. If long time wear mask, will make the nasal mucosa become weak, lost the original physiological function of the nasal cavity, so can not wear mask for a long time. Masks can only be worn in special environments, such as in places where there are many people and air is not circulating. Of course, walking in the wild, in order to resist wind and sand and cold, or in the air pollution environment, it is necessary to wear masks, but the time should not be too long. In addition, in the flu season, to public places where there may be a large number of pathogens, it is also time to wear masks. Wearing masks is only one of the ways to prevent respiratory epidemic, and the most important thing is to adhere to good living habits. Cleaning and maintenance The outer layer of mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer blocks the bacteria and saliva exhaled. Therefore, both sides cannot be replaced. Otherwise, the outer layer of the dirt will

Selection of dust mask Dust mask is a kind of protective equipment for workers engaged in dust operation and touching dust. There are many kinds of masks on the market, and their uses vary greatly. There are paper masks, cotton gauze masks, activated carbon masks, antibacterial masks for food processing, white gauze masks for doctors, welding and dust-proof masks for welders, dust-proof masks for dust operations, self-priming filter respirators for particulate matters, toxic and harmful gas masks, etc. Therefore, when choosing masks, we need to satisfy the needs of workers in different working environments. Improper selection will lead to waste, and even damage workers' health and occupational diseases. Mask In order to save cost, some units bought some low-quality dust masks that did not meet the requirements, and even used some white cotton masks or other ordinary masks as dust masks to distribute them to workers. If workers wear these masks for a long time, they may suffer from pneumoconiosis. Therefore, workers engaged in and touching dust need to understand relevant knowledge, strengthen protection and prevent occupational diseases. In addition to installing ventilation and exhaust equipment, keeping the working environment ventilated, using wet operation, dust isolation and other methods, operators should also be equipped with standard dust masks. The replacement of masks depends on the actual situation. If it is damaged or respiratory resistance is added, it should be replaced. The operator shall wear the dust mask as required, and the nose and mouth shall be completely close to the inner wall of the mask without any

How is medical cotton swabs sterilized? Medical cotton swabs are widely used in medicine, and the technical indexes of the product rules of medical cotton swabs meet the requirements of national standards and industry standards. So, how is the medical cotton swabs sterilized? Medical cotton swabs are usually directly exposed to patients' trauma, and the sterilization process is required to be relatively high. Other is the choice of raw materials for cotton swabs, it is necessary to select the raw materials that meet the requirements of national standards and industry standards. There is also the requirement of bar quality. Whether it is plastic bar, paper bar or mallet, it should meet the requirements of rules and can bear certain external forces without permanent deformation or breaking. According to the national standards and the requirements of pharmaceutical industry standards, the production of degreasing cotton balls is necessary according to the relevant document rules: the quality of the cotton balls is necessary to meet the requirements of YY0330-2002, hold the medical equipment registration certificate, and pass the factory inspection conclusion; the cotton fiber of cotton sign shall be soft, white, odorless, and free from yellow spots, stains and foreign matters.

Medical cotton swabs are made of medical degreasing cotton and natural birch, which can be used in medical and health units and home health care, disinfection of patients' skin, treatment of trauma and application of modified medicine. Cotton fiber o

Sampling method for swab surface Microbiological test on the surface of objects microbiological test on the surface of objects (including work clothes) can confirm the degree of microbial contamination. In general, three methods can be used: cotton swab direct sampling, direct touch sampling and surface washing. When using the direct touch method, the touch disc should be placed at room temperature. The sampling area of swab swab swab surface sampling method is generally 25cm2, and the swab surface should at least include hands, wrists and legs. Direct sampling with cotton swab is suitable for irregular appearance. When sampling, hold the swab handle by hand, touch the sampling surface with an angle of 30 degrees, select S-type or Z-type slowly and rotate the cotton swab to fully scrub. If the swab head is calcium alginate, dilute hydrochloric acid solution should be used as diluent (such as 1% sodium citrate solution), so that the swab head can be completely dissolved. Prohibited plastic products. The production and sale of ultra-thin plastic film with thickness less than 025mm and polyethylene agricultural film with thickness less than 01mm are prohibited throughout the province. The manufacture of plastic products with medical waste as raw materials shall be prohibited. We will stop the import of waste plastics in an all-round way. By the end of 2020, stop producing and selling disposable foam plastic disposable plastic swabs; stop producing daily chemical products containing plastic beads. By the end of 2022, stop the sale of daily chemical products containing plastic beads. Umbilical cord care, in fact, do not stick any protective stickers, but every day to use iodophor press root disinfection, and then must use dry cotton swab press dry. The umbilical cord usually falls off about 10 d

What are the precautions for the purchase of antistatic cotton swabs? Anti static cotton swab is a kind of dust-free scrubbing products, which is designed for highly clean and anti-static environment. Polyurethane sponge, continuous filament polyester fiber and superfine fiber are used as materials for the head of swab, and the swab is treated in Grade 10 (iso4) purification room to ensure the ultra-low ion content and non evaporative residual content of swab (without silicon, ammonia and dioctyl phthalate DOP), And the occurrence of ultra-low particles; the selection of conductive thin shaft can effectively reduce and control its resistance value, conflict voltage, decay time and other ESD parameters, and the perfect edge sealing skills can make the head successfully fixed on the shaft handle, which can effectively prevent the harm of static electricity to the product in the process of application, and also avoid the pollution caused by the use of adhesive. Anti static cotton swab purchase key: Considering the cost: after confirming the application position of the swab, the user needs to select the handle with appropriate length and width according to the actual requirements, confirm whether the swab head needs to be double headed, and then confirm the size and shape of the swab head. Secondly, the user needs to fully understand the quality and application function of each raw material and the packaging required. Generally speaking, double headed swabs are more expensive, and the more messy the shape is, the more expensive they are The better the anti-static function and purification ability, the higher the price will be. Users need to consider the selection of suitable cotton swabs. From the perspective of chemical function, we should select materials such as solvent retention, abs

The production process of medical cotton swabs With the improvement of medical and health level in China, the medical cotton swabs of common medical things have irreplaceable position in medical disinfection and sampling. Because of the large demand of medical cotton swabs, the production of medical cotton swabs is also particularly important. The method of making cotton swabs by hand is unable to meet the increasing demand. In order to improve the production power of medical cotton swabs, we should choose cotton swabs to make machinery instead of handcraft cotton swabs. The method and step of the mechanized medical cotton swabs are more stringent, and the quality of medical cotton swabs can be better ensured. After the compression and cutting of the strip cotton, the medical cotton swab making machine contacts the swab rod through the delivery organization and rolls the cotton. Can be separated into five steps, separation is: delivery, cotton pressure, cotton cutting, delivery of the sign and roll cotton. The first step is to send the strip cotton into the machine at a certain time. The second step is to press the incoming strip cotton to prepare for the third step of cotton cutting. The third step is to cut down the fixed length of the cotton in time. The fourth step is to send the tag to the guide cotton Cao and contact the cotton strip. Finally, the fifth step of the final step is to roll the cotton, rotate the swab and move along the guide slot to complete the cotton roll. The production of medical cotton swabs The specific method of feeding surface is to send strip cotton through the machine cam to the track, and the cam is the active cam. The cam in the machine is connected and rotated, but only one quarter of the contact surface with the strip cotton. The

How to choose high quality medical cotton swabs ? The medical cotton swab is mainly made of medical absorbent cotton and natural birch. Its raw materials include absorbent cotton and bar. The quality of absorbent cotton used to make cotton ball requires that the cotton fiber of the cotton swab should be soft, white, odorless, and free of yellow spots, stains and foreign bodies; the appearance of plastic stick and paper stick should be smooth, burr free, and free of stains and foreign bodies; the outer surface of mallet and bamboo stick should be smooth The meter shall be smooth and free from cracks, stains and foreign matters. Medical cotton swabs are non-toxic, non irritant, good water absorption and easy to use. The storage conditions should be in a room with relative humidity less than 80%, no corrosive gas and excellent ventilation to prevent high temperature. And it has cotton head pull-out force, that is, the cotton coil should be tight inside and loose outside, and it can bear 100g tensile force, and the cotton head does not fall off completely; and it has bending resistance, and the bar should be able to bear 100g external force without permanent deformation or fracture. Medical cotton swabs usually directly touch the wound of patients, so the requirements for sterilization are relatively high. Therefore, for the selection of raw materials for manufacturing cotton swabs, it is necessary to select the raw materials that meet the requirements of national standards and industry standards, and the requirements for the quality of bars. Whether it is plastic bars, paper bars or hammers, they should meet the requirements of rules, and can withstand certain external forces without permanent damage Long term deformation or fracture. What should be paid attention to when using the medical cotton swab

How to use sterile cotton swabs reasonably, have the validity period after opening? You can't be more familiar with cotton swabs. We can buy them in pharmacies. There are many functions of cotton swabs. Many friends have some at home. Have you ever thought about how long the cotton swabs will be valid after they are opened? Let's talk about it! Cotton swabs can be divided into aseptic packaging and non aseptic packaging. Sterile cotton swab refers to the cotton swab that has been disinfected or chemically disinfected after packaging; non sterile cotton swab refers to the cotton swab that has not been disinfected and sent to medical institutions for disinfection and sterilization. The non sterile cotton swabs purchased from pharmacies are not "medical cotton swabs", but "ordinary cotton swabs". They can be used to clean skin and ears, but not for wound treatment. Consumers buy non sterile swabs from pharmacies without disinfection equipment and hospital conditions. If it is directly used for wound treatment, wound infection is likely to occur and can not be cured, and the cotton swab is not disinfected after being opened. In the current hot and humid environment, it is easy to breed bacteria. Sterile cotton swabs can be directly used for wound treatment after opening the bag, but it is difficult to use them all at one time after ordinary families buy medical cotton swabs. Therefore, the cotton swab should be placed in a cool and dry environment after opening, otherwise it is easy to get damp and moldy, and after opening the packaging, the sterile packaging cotton swab may also be infected by bacteria. Therefore, generally speaking, once the package of the sterile cotton swab is opened, the use time should not exceed 24 hours. If it excee

Function of polyurethane sponge mask Polyurethane sponge mask is a relatively common dust mask. The mask is mainly made of polyurethane material with good elasticity and tear resistance. Polyurethane is a kind of polymer material, which is widely used in daily life, such as furniture paint and coating, refrigerator and freezer of household appliances, waterproof insulation layer of roof and interior and exterior wall coating of construction industry. The polyurethane sponge mask has broken the traditional mask's plane structure, and has the three-dimensional support design, has created the three-dimensional space; the fit face, causes the mask to have the good sealing effect; the comfortable cotton lining can restrain the growth of the impurity bacteria; the wide body design is suitable for the ear, the size may freely adjust. Generally speaking, the main function of polyurethane sponge mask is good decoration, sunscreen, dust and pollen. If necessary, you can choose to use it according to your own situation. 1. Can polyurethane masks play a preventive role? Many people like to wear this kind of polyurethane sponge mask when they go out every day, which can prevent moisture and air pollution. However, the preventive ability of polyurethane masks is basically zero, because polyurethane materials have no protective effect, so it is not recommended to wear such masks for self-protection. And polyurethane sponge mask can be reused. If the mask is cleaned with other clothes, it will pollute other clothes, and the more times it is cleaned, the blocking force of the mask will also be affected.

Dust-free cotton swabs are generally used in biomedical, cosmetic, electronic, optoelectronic, semiconductor, optical devices and other industries. For the use of the purification of cotton swab, many people do not have a system of use rules, today we will give you to explain the use of different dust-free cotton swabs. For products of different specifications, we summarize two methods for your reference: For cameras and other micro and precise products: you can arrange the products neatly together, select soft cotton swabs, dip the reagent appropriately, and wipe the products unidirectional until the product surface cleanliness meets the requirements. For uneven products such as circuit board, you can first select a larger cotton swab, appropriate amount of dip reagent, unidirectional wipe large areas, then select a smaller cotton swab, appropriate amount of dip reagent, wipe some corners, cracks and other fine points, until the product surface cleanliness meets the requirements.

There are also many types of products that need to be used in daily life. Sterile medical cotton swabs, because of their use, will be able to make relevant operations in practice more convenient. All these can be well seen from daily use. Such products are not only those large equipment but also many humble appliances whose use is equally important for practical operation. Cotton swabs, for example, belong to such a type of product. Sign type is also now a lot of dust-free purification cotton swabs is actually used in a lot of one type, dust-free purification medical cotton swabs, it belongs to a kind of high cleanliness products type, medical cotton swabs, their use is also a lot of use range is very wide, especially in the medical field for their use is particularly much. A lot of liquids will use such cotton swabs in the smear, for example, the smear of maintenance liquid will use them, their use can make the operation of the smear will be more convenient. Medical cotton swabs are usually in direct contact with the wounds of patients, which requires high requirements for sterilization. In addition is for the production of cotton cotton absorbent raw materials choice, must choose in line with the national standards, industry standards of raw materials. There is the bar quality requirements, Xingtai cotton swab, whether plastic bar, paper bar or wood bar, should meet the requirements, can bear a certain external force does not occur deformation or break phenomenon. The correct use method of medical cotton swab is open bag can be used. Can treat the wound directly. However, care should be ta

Medical cotton swabs are usually in direct contact with the wounds of patients, which requires high requirements for sterilization. In addition is for the production of cotton cotton absorbent raw materials choice, must choose in line with the national standards, industry standards of raw materials. Still have the requirement that is right bar material quality, no matter be model bar, paper bar or wooden bar, should achieve regulation requirement, can bear certain external force to do not produce permanent change or break phenomenon. There are various brands of clean cotton swabs in the supermarket on the market, the price varies a lot, some people may be greedy for cheap. According to the report, the current market there are some inferior cotton swabs, raw material use similar "dirty" the foul after bleaching of cotton production, cotton for neat appearance but also with white latex, production site simply can not meet the hygiene standards, with this kind of material can not meet the standards of health and poor quality cotton swab to wipe the ear canal, not only cannot have clean effect, may lead to illness aggravating instead. So, advise everybody not to be too thrifty in this respect, buy the medical cotton swab that can be trusted to regular store. The cotton swabs in the medicine cabinet should be ster

Cotton swabs, also known as wiping sticks. Cotton swab is a kind of clean wipe consumables used in industry. Most of them are used to wipe the edges, gaps and planes of the electronics and semiconductor industries (some people also call it purifying cotton swab, anti-static cotton swab, sponge stick and so on)... According to the application fields, its varieties can be divided into electronic and photoelectric cotton swabs, medical and cosmetic cotton swabs, household cotton swabs, and other industrial fields. Its materials and shapes are diverse, which can adapt to the wiping of various solvents. Type of cotton swab: there are clean swab, clean swab, medical swab, instant swab. 1. There is an essential difference between a dust-free wipe rod and a cotton swab. The material of the dust-free wipe rod head is divided into sponge head and cloth head, both of which have been treated and purified in a dust-free room. 2. Clean swabs are the only option for precise cleaning applications, eliminating contaminants and maintaining cleanliness in the special environment of the production process. After wiping, the chemical residue content is low, combustible, easy to handle, and environmentally friendly. Most clean cotton swabs are electrically conductive, keeping the operator and tool grounded. Suitable for 10 - level purification workshops, packaging is different. 3. Medical cotton swabs are suitable for cleaning and disinfection of skin or trauma. 4. Instant cotton swab, including cotton swab stick and cotton head fixed on one end of the cotton swab stick, the cotton swab stick is a hollow rod, and its internal storage liquid, one end of the cotton swab fixed cotton head is provided with an oil seal for sealing liquid, and the other end is provided wit
