Метасиликат натрия пентагидрат/безводный

Product Overview

Description

Sodium metasilicate is the chemical substance with formula Na2SiO3 which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na+ and the polymeric metasilicate anions [–SiO2−3–]n. It is a colorless crystalline hygroscopic and deliquescent solid, soluble in water (giving an alkaline solution), but not in alcohols.

Application: detergent, ceramic, textile industry, Paper & Printing, construction, metallurgical industry

- It has the strong capability of cleaning, widely used for the manufacture of a variety of detergents in detergent industry, so it is the best substitute for STPP, reducing environmental pollution.

- Sodium meta silicate provides anti-corrosion protection to metals (zinc, aluminum, etc.) and is used as metal cleaner and metal surface treatment agents.

- In the textile industry: mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.

- In the Paper & Printing Industry: It can be used as adhesives, old paper deinking agent, paper surface treatment agent and printing detergent.

- In the ceramic industry: used for sludge thinners. It is especially suitable for additives used in slip-casting forming and ceramic forming.

- In the metallurgical industry: used as inhibitors and dispersing agent of silicon-containing minerals, smelting furnace dispersants, fast-drying agents, and foundry and separating agents.

- In the construction field: used for concrete dispersion agent and hardening accelerator. It is also used as coagulation accelerator.
