Wolson glass fiber sleeve is made of alkali-free glass fiber woven into a tube, then coated with silicone resin, and then treated at high temperature. Some will add a layer of silicone rubber to make silicone rubber glass fiber sleeve, or add polyurethane to make polyurethane glass fiber sleeve.
No matter how many kinds of materials there are, glass fiber is an indispensable material. Firstly, analyze whether the glass fiber sleeve is harmful to human body. At present, most glass fibers are made of silica, which is harmless to human body, but it cannot be decomposed in human body. In general, glass fiber floating in the air is harmful to trachea and respiratory tract, and it also stimulates the skin, especially for people with allergies. If the glass fiber is larger than 9 microns, the harm is not great, and breathing will not directly enter the lungs. But if you produce yarns below 6 microns, you should pay attention. Yarn with single fiber less than 6 microns can directly enter the lungs through breathing, so it is necessary to wear professional protective equipment during production.
Finally, let's discuss whether the glass fiber sleeve is harmful to human body. When the glass fiber sleeve is in direct contact with human skin, it will not cause any discomfort. Because, after the glass fiber is woven, there will be no burr and other problems, and the outer layer is also coated with a rubber layer to avoid being stabbed by the protruding burr when using the sleeve.
Bian Xiao's friendly reminder: No matter whether the glass fiber sleeve is harmful to human body, if it is really punctured by glass fiber, please wash the affected area with soapy water immediately, and seek medical advice immediately if you feel unwell; The production of glass fiber related products should be equipped with special protective equipment such as masks.
