Acicular wollastonite: wollastonite can replace asbestos which is harmful to human health due to its non-toxic, tasteless and non-radioactive advantages. After special processing technology, it can still maintain its unique needle-like structure, which makes the new environmentally friendly building materials such as calcium silicate board, fireproof board, fiber cement board and calcium sulfate board added with wollastonite acicular powder. The bending strength, wear resistance, corrosion resistance, heat insulation and fire resistance are greatly improved. It can also be used in white cement, construction putty, etc.
Ultrafine calcium carbonate: With the development of industry, a new type of composite material - calcium plastic material has appeared in recent years. It is a building material that uses a large amount of calcium-containing inorganic fillers with a small amount of polyolefin resin and other additives. This material has many excellent properties of wood, plastic and paper, and has the characteristics of heat resistance, chemical corrosion resistance, cold resistance, sound insulation, shock resistance, and easy processing. It can replace paper and wood in large quantities in packaging, building materials, pipes, etc. Chemical building materials are light in weight, cheap and easy to process and form, so they are ideal for doors, windows, ceilings, wall panels, up and down water pipes, ladder handrails, floors, electrical conduits, etc.
