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, absorbency and adsorption capacity, such as foam clinker, polyester material and cotton, which are the raw materials for producing cotton swab heads.
Considering the purification function: the cotton swabs produced from polyester materials have low non evaporation residue (NVR), less particle drop and chemical resistance. Through the analysis of total organic carbon (TOC), it is found that the cotton swabs woven with purified polyester materials can release less particles, have good recovery and low TOC background level.
Considering from the application method: whether the selected cotton swab meets the application specification of the product in the actual application process, such as adding any solvent, should be considered in advance.
Precautions for application:
When using the cotton swab, the amount of solvent should not be too much, otherwise it will leave solvent marks on the products that remove the stains, and it is not easy to be cleaned. In addition, the solvent suitable for the product requirements should be selected and blended. Do not use strong acid or strong alkaline solvent to avoid harm to the products;
Cotton swabs are disposable consumer goods, which should be cleaned by changing the surface according to the area of the swabs. It is not allowed to use one surface repeatedly, otherwise it will cause interpenetration pollution to the products;
After opening the packing bag, the swabs to be used should be placed in a clean place, such as a professional swab box, but not too many at a time, and then removed after use, so as to avoid being polluted for too long and affecting the application effect;
When using cotton swab in clean room, it should be avoided to break the cotton swab. This action will also have certain pollutants;
The used cotton swabs should be treated professionally, and they should be classified as class C treatment because they contain solvent residues.
