How does the head and stem of the purification swab join?
The first: directly stick the head of the purification cotton swab directly to the rod
Some manufacturers will use glue, some will use other sticky substances, and the result is that as long as the head is glued on, it will not fall off. Although such a production process is very convenient to produce, in industrial use, this kind of product cannot be used at all, because they will have some residues on them, which will cause the residues to fall on the product and cause secondary Pollution, poor cleaning effect.
The second: heat sealing principle
First, hot-press the head of the purification cotton swab with hot air, and our purification cotton swab uses such a production process. Because hot air can blow off some of the original dust on the cotton swab, and the cotton swab head and the cotton swab shaft are more closely joined together, leaving no residue, and the cleaning effect is good. Can be used longer!
The third type: production using ultrasonic waves
The principle is to use high-frequency vibration waves to transmit to the surfaces of two objects to be welded, and under pressure, the surfaces of the two objects are rubbed against each other to form fusion between the molecular layers. Although the quality of cotton swabs produced by ultrasonic is the best, its cost is not low.
