The technology is simple, allows solid water glass to be produced, effectively saves energy consumption in the production process, reduces the resource investment for heating of the solid water glass, improves the resource utilization rate, and improves the water glass production quality, and the quality of the produced solid water glass is good.
Description
Technical field
The present invention relates to a kind of preparation technology of sodium silicate.
Background technology
Water glass (Na
2si0
2), have another name called sodium silicate, water glass (XNa
20.YSi0
2), colourless, dark green or brown solid or thick liquid, sodium silicate purposes widely, almost throughout each department of national economy, be used for manufacturing silica gel, white charcoal ?, zeolite molecular sieve, Starso silicon sol, layer silicon and instant powdery sodium silicate at chemical system, the various silicates product such as sodium-potassium silicate is the basic raw material of silicon compound; Being indispensable raw material in the lotion such as washing powder, soap in light industry, is also the light agent of water quality, washing assistant; For helping dye, bleaching and sizing in textile industry; Casting, emery wheel manufacture and anticolodal etc. are widely used in machinery industry; For the manufacture of rapid hardening cement, acid-proof cement dubbin, soil-solidified-agent, refractory materials etc. in building trade, in addition, as tackiness agent; Si0 is used in medical
2refine, non-phosphorus builder best at present.
Summary of the invention
The object of this invention is to provide a kind of sodium silicate preparation technology, effectively can save energy consumption, improve resource utilization, promote sodium silicate production quality.
In order to solve the problem existing for background technology, the present invention by the following technical solutions:
