Production process and application of glass fiber mat
二、 Factors affecting the strength of glass fiber mat
Is Glass fibre fabric the same as glass?
Woven roving fabric is made of glass into very thin glass filaments, and the glass filaments at this time have good flexibility. Spin the glass fiber into yarn purchase, and then use the loom to weave fiberglass cloth. Since the glass filament is very thin and the surface area per unit mass is very large, the temperature resistance performance is reduced. It's like melting a thin copper wire with a candle.
But glass is not a burning body. The burning that we can see is actually the resin material coated on the surface of the glass fiber cloth to improve the performance of the glass fiber cloth, or the attached impurities. After pure glass fiber cloth and some high temperature resistant coatings are applied, it can be used to make products such as refractory clothing, refractory gloves, and refractory blankets. However, if it is in direct contact with the skin, the broken fibers will irritate the skin and it will be very itchy.
What are the factors that affect the strength of glass fiber chopped strand mat
1.Adhesive, the manufacturer will formulate the production requirements of chopped strand felt according to the customer's use process.
2.Some people may not understand that any product will have a shelf life, and glass fibre felt is no exception. Glass fiber chopped strand mat is made of adhesive. After a long time, the adhesive will age, and the moisture in the air will erode the mat and affect the strength of the mat.
3.The direct factor that affects the strength of the felt is the cutting strength during production. The greater the cutting strength, the greater the impact on the strength of the felt, and the easier it is to tear the felt.
