Sodium metasilicate pentahydrate is a common chemical raw material, which is widely used in washing, ceramics, building materials, metallurgy and other fields. The upstream and downstream related products of sodium metasilicate pentahydrate mainly include the following categories:

1. Upstream product

The upstream raw materials of sodium metasilicate pentahydrate are mainly soda ash and quartz sand. After a certain proportion of soda ash and quartz sand are mixed and calcined at high temperature to generate solid sodium silicate, and then add appropriate amount of water to obtain sodium metasilicate pentahydrate.

2. Downstream product

(1) Detergent

Sodium metasilicate pentahydrate can be used as one of the main components of detergent, with good decontamination ability and hard water resistance. During the washing process, sodium metasilicate pentahydrate can react with calcium and magnesium ions in the water to generate silicate precipitates that are not easily soluble in water, thereby removing stains on clothing.

(2) Ceramic

In ceramic production, sodium metasilicate pentahydrate can be used as a reinforcing agent and water reducing agent for ceramic bodies. It can improve the mechanical strength and hardness of the ceramic body, reduce the drying shrinkage of the body, and prevent cracking and deformation.

(3) building materials

sodium metasilicate pentahydrate can be used as concrete admixture to improve the performance and strength of concrete. It can improve the fluidity and pumpability of concrete, reduce bleeding and segregation, and improve the compressive and flexural strength of concrete.

(4) Metallurgical

In the metallurgical industry, sodium metasilicate pentahydrate can be used as a smelting flux to help reduce the viscosity and surface tension of the slag, improve the fluidity of the slag, and facilitate the discharge of the slag and the separation of metals.

In short, sodium metasilicate pentahydrate, as an important chemical raw material, is widely used in various fields, and its upstream and downstream related products are also very rich.
