Sodium metasilicate pentahydrate in terms of the production process, sodium metasilicate pentahydrate manufacturers boil it down to three forms:
One is five water sodium metasilicate "continuous granulation method", is the sodium metasilicate solution through granulating crystallization device, direct cause for the size of the particles in a row, quality indicators conform to the requirements of the standard HG/T2568-94, the spherical particles, the appearance of product is high whiteness, good liquidity, it belongs to high grade product, the method is suitable for mass production but strong technical is not easy to master.
The second is sodium metasilicate pentahydrate "crystal dehydration method". "Crystallization dehydration method", also known as the mother liquid circulation method, is to add sodium metasilicate solution to crystal seed or mother liquid to cool down crystallization. After centrifugal dehydration, dynamic drying screen can be obtained to obtain powder pellet products. This method is relatively difficult to produce in large scale, but the product appearance and fluidity are relatively good.
Three is five water sodium metasilicate "crystallization FenSuiFa" this kind of method is will be concentrated to the required concentration, sodium metasilicate solution by adding seed crystal and additives to guide all into a block solid solution, all free water into water of crystallization, the solid is the finished product after crushing, the advantage of this approach is less investment, but more serious damage to the crystal structure, the climate is quite harsh environment and control requirements, low labor strength, product whiteness, easy absorption of moisture, agglomerate, physical and chemical indicators generally short of HG/T2568-94 standard requirement. The granular product is dust-free and can meet the export requirements. The latter two methods produce the powder granule product to use the dust big, the export is restricted.
Different methods may have different characteristics, but now, the above three methods are sodium metasilicate pentahydrate manufacturers for sodium metasilicate pentahydrate is more common production process.
