Abstract
A process for praparing sodium silicate includes such steps as mixing natural quartz sand containing Al (0.5-0.7%) with sodium carbonate in weight ratio of (1.7-2.09):1, stirring to uniformity, and fusion reaction at 1250-1500 deg.C for 30-50 hr in furnace. The resultant has high Al-content (0.45-0.55 wt%), which causes the variation of white carbon black in physico-chemical properties prepared from the said sodium silicate.
Description
Technical field
The present invention relates to a kind of production method of novel water glass.
Background technology
One of water glass main application is as the raw material of producing white carbon black, in the prior art, with fusion under low quartz sand of aluminum content and the soda ash high temperature and the water glass of producing, the problem of its existence is: aluminum content is low, it is little to do the white carbon black tap density that raw material production comes out with it, has only 0.20～0.24 gram/cubic centimetre; Be difficult for carrying, promptly mobile bad, the slope of repose is 38～48; Dust is many, by 200 purpose dusts between 10%～30%; Behind the adsorptive liquid, the caking thing is many, reaches 2%～10%; The meta particle diameter is between 120～180 microns, and particle is not attractive in appearance.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, having proposed a kind of novel white carbon black production raw material is the production method of water glass, and the water glass of producing with the present invention is function and the characteristic that white carbon black that raw material production is come out can improve white carbon black.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of production method of water glass, be characterized in: by weight percentage, with the natural siliceous sand of aluminum content 0.5%～0.7% and soda ash 1.70～2.09: 1 mixed by weight ratio, stir, drop in the kiln, under 1250 ℃～1500 ℃ high temperature, frit reaction discharging after 30～50 hours.Its main component weight content of the high alumina quartz sand that is adopted is: SiO
2% is 99.2%～99.5%, Al
2O
3% is 0.5%～0.7%, TiO
2% is 0.03%～0.05%, Fe
2O
3% is 0.01%～0.03%, CaO% is 0.02%～0.04%, MgO% is 0.01%～0.03%.Because the increase of aluminium content caused the increase of aluminium composition in the water glass, and it is as the raw materials for production of white carbon black in the quartz sand, in the process of producing white carbon black, the subsidiary physicochemical change that is taken place causes the physical properties generation considerable change of white carbon black.
The technical problem to be solved in the present invention can also come by the following technical programs further to realize that the dry method discharging is adopted in its discharging, promptly directly goes out in module, and naturally cooling generates solid-state water glass then.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, the wet method discharging is adopted in its discharging, when promptly being cooled to 50～160 degrees centigrade, puts into dissolution kettle, in dissolution kettle, feed the steam of 0.55～0.6 MPa then, generate liquid water glass.
The present invention compared with prior art, adopt the weight percent of its aluminium content of water glass that high quartz sand of natural aluminum content and soda ash produces to reach 0.45%～0.55%, the water glass of producing with the present invention is the white carbon black that raw material production is come out: its tap density is big, 〉=0.29 gram/cubic centimetre; Easily carrying, good fluidity, the slope of repose is 32～34; Dust is few, by 200 purpose dusts no more than 2.5%; Behind the adsorptive liquid, the caking thing is few, and no more than 0.2%; Particle is attractive in appearance, and the meta particle diameter is between 200～300 microns.
