Sodium metasilicate pentahydrate is a crystalline substance with a relative bulk density of 0.8-1.0 g/ml, a melting point of 72.2 ° C, and a relative molecular weight of 212. It is easily soluble in water and dilute alkali solutions, insoluble in alcohols and acids, and has an alkaline aqueous solution. It is prone to moisture absorption and deliquescence when exposed to air; Strong stain removal ability and high pH buffering capacity; Has good properties such as descaling, emulsification, dispersion, wetting, and permeation.

Sodium metasilicate pentahydrate provides excellent buffering alkalinity in washing solutions, provides corrosion protection for light metals such as aluminum and zinc, protects glassware and porcelain, and has properties such as suspending and emulsifying dirt, as well as softening water.

Cleaning industry
Widely used in various cleaning industries. In the washing industry, such as ultra concentrated laundry detergent, laundry detergent, laundry cream, dry cleaning agents, fiber laundry bleach, etc; It is also widely used as a metal surface cleaner, beer bottle cleaner, and food utensil cleaner. After full dissolution, it can be used as a metal rust inhibitor, scale cleaner, and electrical component cleaner, and can be used as a detergent in the food industry.

Oil drilling
In crude oil and natural gas drilling and mining engineering, it can be used as a mud consistency regulator and mud demulsifier.

Construction industry
Used as a coagulant for preparing acid resistant mortar, acid resistant concrete, and cement.

paper industry
Can be used as an adhesive, waste paper de ink agent, and paper surface treatment agent.

textile industry
As a printing and dyeing auxiliary and fabric pretreatment agent.

ceramic industry
Adding pentahydrate sodium metasilicate to the slurry can increase the surface negative charge of alumina particles, utilize the charge repulsion effect to reduce the viscosity of ceramic slurry, increase fluidity, and improve efficiency and product quality in ceramic grouting technology.

Other uses
Can be used as a filler for soap, detergent preservative, mineral flotation agent, sulfuric acid, and fire-resistant material. It can provide excellent buffering alkalinity in the washing solution, provide anti-corrosion protection for light metals (aluminum, zinc, etc.), protect glassware and porcelain, suspend emulsified dirt, and have a certain softening effect on water.
