Sodium Metasilicate Anhydrous
Product Name:
Zero water sodium metasilicate, alias anhydrous sodium metasilicate.
Molecular formula:
Na2SiO3。
Product appearance:
White particles or powder.
Performance purpose:
The relative bulk density of zero water sodium metasilicate is 1.05-1.35 g / ml, the melting point is 1089 ℃, and the relative molecular weight is 212. It is a non-toxic, tasteless and pollution-free product; Soluble in water, insoluble in alcohol and acid, alkaline aqueous solution, easy to absorb moisture and deliquescence in air; Strong decontamination capacity and large pH buffer capacity; It has excellent performances of descaling, emulsification, dispersion, wetting and penetration.
As a detergent additive, the product is especially suitable for the production of super concentrated detergent, industrial detergent and metal surface treatment agent; As the main raw material of additives, it is used in the pretreatment of textile printing and dyeing industry in the fields of cooking and bleaching of cotton spinning, decontamination and bleaching of papermaking industry, paper deinking agent, ceramic grinding aid and water reducer, etc; At the same time, it is also widely used in refractory raw materials, plastic and water retaining agent raw materials, mineral oil recovery, dispersant and quick drying agent for construction and metallurgical industry, oilfield drilling accelerator, water quality treatment, etc.
