Anhydrous and Hydrated Sodium Metasilicate: How to Choose Suitable Industrial Specifications

Sodium Metasilicate has two mainstream specifications: anhydrous type and hydrated type. Water content difference leads to distinct physical property and applicable scene. Industrial buyers need to distinguish characteristics and select matched products for targeted production demands.

 

Anhydrous sodium metasilicate contains no crystal water, featuring strong alkalinity, fast reaction speed and good drying resistance. It fits high-temperature working environment and formula requiring low moisture content, not easy to deliquesce and deteriorate.

 

Hydrated sodium metasilicate carries fixed crystal water structure, with mild chemical activity and moderate solubility. It is convenient for daily normal temperature use and easy to mix evenly with other auxiliary materials, widely used in conventional cleaning and common industrial auxiliary links.

 

Alkaline strength and decontamination efficiency of anhydrous product are higher than hydrated product. Users pursuing high-strength cleaning effect prefer anhydrous Sodium Metasilicate. Conventional daily production chooses hydrated type to control reaction intensity and avoid material corrosion damage.

 

Unit price and storage stability also have difference between two specifications. Anhydrous type has higher cost and stricter moisture-proof requirement. Hydrated type owns cost advantage and simple preservation condition. Reasonable specification selection balances using effect and procurement expenditure effectively.
