what links do we need to pay attention to in the use method? Next, I will talk to you about the precautions in the use of glass fiber cloth?
One of the usage methods of glass fiber cloth: glass fiber cloth is made from glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several microns to more than 20 meters, which is equivalent to 1 / 20-1 / 5 of a hair filament. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments.
The second method of using glass fiber cloth: glass fiber cloth is mostly used in hand pasting process. Glass fiber reinforced square cloth is mainly used in hull, storage tank, cooling tower, ship, vehicle, tank and building structural materials. Glass fiber cloth is mainly used in industry: heat insulation, fire prevention and flame retardant. The material absorbs a lot of heat when burned by flame, and can prevent the flame from passing through and isolate the air.
The third method of using glass fiber cloth: glass fiber cloth is to draw glass into very fine glass filaments. At this time, the glass filaments have good softness. The glass fiber can be spun into yarn and then woven into glass fiber cloth through a loom. Because the glass fiber is very thin and the surface activity per unit mass is large, the temperature resistance decreases. It's like melting thin copper wire with a candle.
The fourth method of using glass fiber cloth: generally, the glass fiber floating debris with the diameter of conventional glass fiber monofilament above 9-13 microns and below 6 microns can directly enter the pulmonary tube and cause respiratory diseases. Therefore, special attention should be paid to that most of the glass fiber floating debris below 6 microns are imported now. Professional masks must be worn during production operations. If exposed frequently, it may be sucked into the lungs and cause pneumoconiosis.
If the body is stained with glass fiber, the skin with bad skin will be allergic and itchy, but generally there will be no major harm. The skin with bad skin may have small bags. That is an allergic phenomenon. Just take some anti allergic drugs. If it's difficult to remove clothes, pat them several times in windy places. After washing and drying, it's easier to remove them by patting them with branches. Pat them several times more!
