Calcium sulfate whisker combines the advantages of reinforcing fiber and ultrafine inorganic filler and can be used as reinforcing and toughening agent or functional filler in resin, plastic, rubber, coating, paint, papermaking, asphalt, friction and sealing materials. It can also be directly used as filter material, thermal insulation material, refractory heat insulation material, infrared reflection material and high insulation material covering wire. Adding calcium sulfate whisker to the composite material can improve the stability, heat resistance and dielectric property of the product. Reduce the shrinkage and water absorption of the product. Adding whisker products to ceramic - and metal-based composites can play a toughening and reinforcing effect.
Adding calcium sulfate whisker to friction material using calcium sulfate whisker, enhance the asbestos-free friction sheet, a number of properties, small pollution, stable physical properties, at the same time, the friction coefficient is stable, high wear resistance and heat resistance, greatly improve the mechanical strength, and in the use of small noise, the dust generated non-toxic. The product is easy to manufacture, cheap, long service life.
Calcium sulfate whisker is a kind of micro short fiber, with good chemical stability, excellent high temperature resistance, high whiteness, high adhesion rate, good affinity, easy to chain and other advantages, in the presence of additives in the colloid state, has a strong adsorption, and plant fiber (wood pulp, straw pulp) well combined together, can make excellent performance of paper. As a paper filler, it can greatly increase the yield of paper, reduce the consumption of wood (wood pulp), and reduce the pollution caused by waste water discharge in papermaking.
Calcium sulfate whisker is added to thermal insulation materials as a modification additive for thermal insulation and sound insulation materials. It has excellent physical and chemical properties and excellent mechanical properties, and has good application value. It is a new inorganic whisker material with excellent price and quality among all whisker products.
