Wollastonite, mainly composed of Ca3Si3O9, is a sheet, needle or fibrous crystal with good hardness, brittle texture and glass luster. Wollastonite mineral fiber is one of the products produced by wollastonite processing. Due to its good thermal stability, chemical corrosion resistance, insulation and low moisture absorption, it can be used as reinforcement materials, insulation materials, friction materials for papermaking, plastics, rubber, automobiles, building materials and other fields.

Wollastonite needle like powder: the ratio of length to diameter is>10 ∶ 1, which is mainly used as paint pigment, rubber and plastic reinforcing agent, fibrous filler of friction materials for clutch brakes such as automobiles.

In the paper industry, wollastonite mineral fiber can replace part of plant fiber, improve the mechanical strength of paper, and the price is low. Wollastonite is a white fibrous crystal, which can improve the whiteness, refractive index, opacity and evenness of paper. It can be used to produce newsprint, offset paper, writing paper and other cultural paper. Wollastonite fiber has good thermal stability, corrosion resistance, insulation and other properties. On this basis, special paper can be produced. In general, wollastonite mineral fiber used in manufacturing can improve the paper quality and product added value.

In plastic and rubber industry, wollastonite mineral fiber can be used as reinforcement filler instead of glass fiber. It has obvious effect in improving the bending strength and tensile strength of plastic rubber, and can greatly reduce the production cost of modified plastic rubber products. It can be used to produce epoxy resin, polyethylene and polypropylene. Wollastonite fiber has low hygroscopicity, and can also be used to modify nylon and other products to reduce the water absorption of products.

Downstream utilization analysis of wollastonite fiber The enterprises with strength have more development advantages. Wollastonite fiber, as a friction material, is mainly used to manufacture automobile brake pads in the automobile industry. In early China, asbestos was mainly used as friction material for automobile brake pads, but asbestos could cause diseases such as asbestosis and pleural mesothelioma, which had been banned in 2003. Wollastonite mineral fiber has good hardness but great brittleness. It can be mixed with other fibers for the production of automobile brake pads to improve the wear resistance and hardness of automobile brake pads.

It is analyzed that enterprises with strength in downstream utilization of wollastonite fiber have more development advantages. In China, there are a large number of wollastonite fiber manufacturers. Hubei Fengjiashan Silicon Fiber Co., Ltd. is one of the representative enterprises, specializing in the manufacturing and application development of wollastonite fibers, which can produce high-purity, ultra-fine, ultra long and highly active products. According to the downstream use analysis of wollastonite fiber, enterprises with strength have more development advantages. Wollastonite fiber is a kind of natural fiber material, which can be widely used in papermaking, plastic, automobile and other industries. China is rich in wollastonite mineral resources and the largest wollastonite producer in the world, providing sufficient raw materials for the development of wollastonite fiber industry. In China's wollastonite fiber industry, enterprises generally have the qualification to mine wollastonite ore. With the increasingly strict national supervision, enterprises with perfect upstream and downstream layout, large scale and advanced technology have more development advantages.
