What are the reasons for the bursting of the purification swab?
In the production process of purified swab, it needs to be processed by layers of technology, such as the manufacturing of swab rod, the hot pressing of swab head and the clarity. Through each process, if the quality of the swab itself is not very good, it will present a large number of burst phenomenon.
What is a Cotton Swab burst? Careful friends may find that all the dust-free swabs are hot pressed when using swabs, but some of them can't reach the technological level, resulting in the sponge cracking on the head when packing or cleaning the swab itself, which is the so-called swab burst.

Why is there a clean swab burst? The reasons for the burst of the cleaning swab are as follows:
1. The quality of raw materials (sponges) used is not up to the standard, because sponges are also graded. In order to save cost, some purification swab manufacturers purchase lower grade sponges, which makes it easy for swabs to burst.

2. If the technology is not up to the standard, the hot pressing level is not sophisticated. Only the right hot pressing level can guarantee the quality of the cotton swab. If the temperature of hot pressing is too low, the head of cotton swab can't blend effectively. If the temperature is too high, the head of cotton swab will be damaged.

3. Another point is that the cotton swab manufacturer does not have strict quality control. If the production process is strictly standardized and the production requirements of workers are improved, this kind of phenomenon can also be avoided.
