The broken glass fiber is made by grinding the raw glass fiber filament through some machine powder.Although this ground glass fiber is small, it is very useful.
With the rapid development of science and technology, the application of ground glass fiber has been expanding and the production has been increasing.At present, there are many units in the production of broken glass fiber.As things stand, the us dominates the industry.
At present, this kind of products in our country are mainly used for high performance friction materials.The traditional filler of friction material is asbestos.However, asbestos is reported to be carcinogenic in foreign countries, because the international market has resisted the friction materials containing asbestos in recent years, providing a wide market for ground glass fiber.
The ground glass fiber used as friction material is chemically treated on the surface to accelerate the penetration of resin and meet the special requirements of molding performance and product performance.Its specifications are emf-200, emf-250 and emf-300, and its corresponding fiber length fluctuation range is 110 ~ 80 microns, 80 ~ 50 microns and 50 ~ 30 microns.
Added ground glass fiber friction material has not only high friction coefficient, and excellent durability, thermal stability, the frictional contact with tiejin parts (rotor), only a slight noise, and cause the friction parts wear is reduced to a minimum.
The high performance of friction material can be widely used in automobile brake pads and clutch plate, passenger and cargo vehicles, railway locomotive brake shoe and all kinds of drilling RIGS, stamping equipment and mining machinery engineering friction block, and hoisting machinery cone brake ring, etc.
Ground glass fiber can also be used as functional filler of ABS plastic to modify ABS plastic to meet the requirements of plastic processing and product application.
One power plant in the process of production of fully automatic washing machine controller base plate and the cover board and other components, because the pure ABS plastic manufacturing, the base plate and the cover plate of the board face serious buckling deformation, parts size is not stable, screw hole nail slip teeth, make a lot of finished product could not be assembled and scrap.Later use ground glass fiber filled ABS plastic, the plastic modification: shrinkage rate reduced to 0.4% from 1% ~ 1% ~ 0.5%, and in turn self tapping screw, not sliding teeth, no crack, at the same time made and components to the board face level off, crisp, not buckling deformation, plastic processing performance is good.
In addition, adding ground glass fiber to laminate can improve the crack resistance and abrasion resistance of laminate, reduce the shrinkage of laminate and improve the laminated strength.At the same time, it can also improve the flexural elastic modulus and compressive elastic dies of laminate.
Join the ground glass fiber resin mixture used in the mould, can the surface leveling defects, repair round the edges and corners of the mould structure, also can fix round connection in advance to the outside of the mold structure coated with glass cloth reinforced rib.
The hardness of the product is relatively high after curing with ground glass fiber reinforced resin, and its thermal expansion performance is similar to that of hand-shaped glass fiber reinforced with glass cloth, and the product is not easy to crack.
The use of both surface active components and ground glass fiber in the resin system can improve its wet strength performance, reduce water absorption and improve the retention rate of wet strength.
