The production technology of Anhydrous Sodium metasilicate

　　sodium metasilicate Anhydrous is light or lumination grey grain. Its molecular formulation is Na2SiO3(Na2O.SiO2).

　　Production technology:

　　First one: steady granulation. Transform the remedy of sodium metasilicate into steady granules of particular sizing as a result of granulation crystal devices. The level of quality indicators can meet up with theprinciples of HG/T2568-94. The supplement is high-grade spherical granule with substantial whiteness and decent fluidity. This technique is appropriate for substantial production, however the technological innovation is just not effortless to master.

　　Second one: Crystal dehydration or mom liquor blood flow method. introducing seed crystal or mom liquor on the remedy of sodium metasilicate, then dried up and sieve it dynamically soon after centrifugal dewatering to acquire granular or powdered product. it can be complicated because of this technique for being utilized to substantial production. However, its look and fluidity is excellent. In addition, its level of quality indicators can meet up with the principles of HG/T2568-94 as well.

　　Third one: Crushed crystal method. Concentrate the remedy of sodium metasilicate to particular concentration, then include seed crystal and additive to prompt the remedy to crystallize into stable block. When allfree of charge h2o transforms into crystal water, the supplement may be obtained soon after stable smash. This technique demands much less investment, but it may lead to considerable destruction to crystal structure, along with the requests for conditions and manage needs are strict. introducing in the substantial labour intensity, very low whiteness and effortless deliquescence, bodily and chemical substanceindicators typically cannot achieve the needs of HG/T2568-94.
