Ultrafine calcium silicate is an inorganic non-metallic material, a functional powder prepared by grinding, classifying, purifying and removing impurities through a special process. The chemical formula is CaSiO and it is mostly a white powder with needle-like crystals. Odorless, non-toxic, soluble in strong acid, insoluble in water, alcohol and alkali. Performance characteristics: high strength, it is the strongest insulation material among inorganic hard insulation materials ; good heat resistance, no deformation within the operating temperature range; good thermal insulation, and lower thermal conductivity than other hard block insulation materials ; It has good flame-retardant properties and is a flame-retardant and fireproof material that does not contain asbestos; it has good stability, is antibacterial, mildew-resistant, aging-resistant and corrosion-resistant.

Ultrafine calcium silicate is widely used in functional applications due to its outstanding synergistic flame retardancy (applicable to phosphorus nitrogen series, piperazine series, antimony trioxide, magnesium aluminum, etc.), shell-forming, porcelain-forming, weather resistance and heat resistance. Polymer modified and flame retardant fireproof materials. For example, adding ultrafine calcium silicate to fire-retardant coatings significantly delays the ignition time of the coating, reduces its heat release rate, total heat release and total smoke production. After the coating is burned, a complete, dense and uniform charcoal is formed. layer.

In addition, it is also widely used in desulfurization in power plants and aluminum plants; making plastic pipes and sheets, dewatering masterbatch; making plastic films, dewatering masterbatch; papermaking, insulation materials, coatings, plastics, rubber, automotive interior materials, air purification materials, plastics Film, etc.
