Instant sodium silicate dehydration process

2014-07-27
Desription:

Instant liquid sodium silicate is using instant dehydration process to produce a multi-class amorphous silicate, white powdery solid, non-toxic, tasteless, easy to dissolve in water, aqueous solution is alkaline and sticky. With the nature of the molecule and the silica and sodium oxide ratio of the different materials and different amounts of silica to sodium oxide molar ratio is called the modulus, the modulus of its technical specifications of the most important one.

Instant sodium silicate used as furnace gunning, castable, acid resistant clay binders, replacing liquid sodium silicate binder can be made single dosage form acid resistant clay material and insulation pouring with ordinary double dosage forms (solid , liquid).

Easy to use and storage features, particularly in the acid corrosion in the construction equipment is easy to use. Instant activation of sodium silicate ash is also used as aids, added to reduce costs and improve material strength in cement.

Instant sodium silicate raw material used in the production are: liquid sodium silicate, liquid caustic soda (mass fraction of 30% to 40%); diesel or natural gas as fuel.

Sodium silicate is purified instant cleaning, liquid caustic soda to adjust the modulus, and a small amount of additives, and the reaction under the above conditions 80e, the instant dried (spray drying) obtained in the process.
