East Chem Sodium metasi\licate pentahydrate

Technical Data Sheet (TDS)   of Sodium metasilicate pentahydrate

1. Introduction

Sodium Metasi\licate had been used for a long time in alkaline clearing agents for the household and industrial sectors. Sodium Metasi\licate provides both silica and alkalinity in a molar ratio of 1:1 between silicate and sodium\ oxide, which makes it especially suitable for hard surface cleaning. Its multifunctional cleaning properties enhance the removal of fatty and particulate soil in both soft and hard water. The corrosion inhibiting properties of Sodium Metasi\licate help protect both metal and non-metal surfaces.

Applications of sodium metasilicate

(1) In Detergent industry:

a. 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.

b. Sodium metasi\licate provides anti-corrosion protection to metals (zinc, aluminium, etc.) and is used as metal cleaner and metal surface treatment agents.

(2) Scouring of Textiles:

mainly used as printing and dyeing auxiliaries, fabric pre-treatment agent and as detergents in cooking and dyeing cotton yarn.

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

(4) Enhanced oil recovery

(5)Refractory and acid resistant cement

(6)Lithographic process

(7)Waste treatment

(8)Paper coatings

(9)Ore flotation

(10)Refining of natural oils

5. Packaging

Sodium Metasi\licate Pentahydrate is asvilable in bags,net weight 25KG,

Big bags, and bulk.

6. Storage

Dry sodium silicates are hygroscopic products and adsorb water from the ambient air.sodium metasi\licate pentahydrate should be stored in a cool and dry warehouse in its original package protected aginst moisture.When

Delivered in bulk to a silo,Sodium Metasi\licate Pentahydrate must be protected against moisture.

7. Handling and Safety

Sodium Metasi\licate Pentahydrate is a strongly alkaline product and should be handled with care in order to prevent injuries.
