What is Wollastonite fiber? Application of wollastonite fiber in production

Wollastonite is a naturally occurring metasilicate mineral with the molecular formula CaSiO3 and the structural formula Ca3 [Si3O9]. It belongs to a three-layer crystalline system, usually in the form of needle-shaped and fibrous agglutination, white, sometimes light gray in color.

Wollastonite has a needle-like physical structure and stable chemical properties, it has high temperature resistance, wear resistance, corrosion resistance, reinforcement reinforcement and it is non-toxic, odorless, friendly. to the environment. Wollastonite is widely used in functional coatings, rubber in the fields of plastics, friction materials, construction materials, papermaking, metallurgy and other fields.

APPLICATION AS CONSTRUCTION MATERIALS

Wollastonite fiber has the advantages of non-toxic, odorless, non-radioactive, can completely replace asbestos harmful to human health and partly replace fiberglass, helping to minimize environmental pollution, reduce production costs. production without affecting the performance of the building material. Wollastonite fiber is the new raw material for environmental protection building materials in the new century.

As an inorganic mineral fiber product, wollastonite fiber is used for a long time in many building materials, such as calcium silicate sheet, fiber cement sheet, fireproof and soundproof sheet, … useful for use as impact-resistant materials and products with good corrosion resistance, sound insulation, heat insulation, fire protection, heat insulation and other properties.

The particle size of wollastonite fiber used in the building materials industry is from 100 mesh to 800 mesh. The grain size, shrink ratio and fiber purity determine its application in different types of building material products.

APPLICATIONS IN PAINTING AND FINISHING INDUSTRY

Wollastonite fiber has anti-wear, anti-corrosion and anti-UV properties. Wollastonite fiber can not only improve many product properties in paint application and coating products but also play an important role in cost reduction. The function of wollastonie in paints and coatings industry is:

1.It can be used to replace white substances such as titanium dioxide, which has a covering effect, increases the thickness of the paint film, makes the paint film plump, firm, wear-resistant, reduces cracking

2. Wollastonite has a high refractive index which makes the product color purer and shows bright colors. High refractive index can also make the paint film capable of blocking the penetration of light and ultraviolet rays, helping to prolong the service life of the paint film.

3. Wollastonite fiber can be used in polypropylene corrosion resistant coating, its needle structure can make the coating with high surface gloss, erosion resistance, better waterproofing.

4. Wollastonite fiber has a low coefficient of expansion, and for the high temperature resistant coating, it can improve the thermal stability of the product.

APPLICATION IN THE PURPOSE INDUSTRY

In the ceramics industry wollastonite is used to make: enameled tiles, sanitary wares, daily-use porcelain, art ceramics, electric porcelain, chemical ceramics, pigments, glass, molds, etc. The main functions of wollastonite used in the ceramic industry are:

1. Reduce the heating temperature

2. Shorten heating cycle

3. Wollastonite can promote the improvement of ceramic production process, kiln structure, firing process and operating method thanks to the advantages of energy saving, low temperature heating, time saving and improve the physical and chemical properties of the product.

4. Because wollastonite has a lower coefficient of expansion and lower water solubility, wollastonite can reduce heating shrinkage, significantly change deflection and cracking of the product, and make it easier to shape the product. Products

5. The use of wollastonite can optimize the quality of the ceramic glaze and improve the quality of the glaze.
