Performance and Usage:
Magnesium Aluminum Silicate is the three octahedra layers of form silicate mineral colloidal material. The chemical compositions are: SiO2 50.0~52.5%; Al2O3:4~8;MgO 23~55%; Na2O2:23~55.0%. 1000C burned the losing amount:10~12%. The gel is the white powder, nonpoisonous, nonirritation. Big characteristic is that it can disperse rapidly among water system, form the card-type palace structure containing a large number of H2O mol. And it becomes to have the strong glue performance in the lower solid content. The excellent performance of the Magnesium Aluminum Silicate plays a wide applications for cosmetics , the articles for washing , coating , paint , daily-used chemical industry products , potassium battery, print and dye auxiliary , slippery pharmaceutical , purifying fields such as pharmaceutical ,etc.
Colloid property: It scatters in the water to hydrate, swell to become "translucent-transparent" thixotropy gel. The Geling process is not limited by the temperature. It can be dispersed or hydrated in the hot or cold water.
Antiacid, antisalinity and dissolved salt property: The dispersed water is added a little acid, alkali, salt etc, the electrolyte will not change the gel to the diluted、flocculated. It has the big compatiable with electrolyte. The stablity of the gel is good enough.
Suspension property: It's a good floating material for the non-dissolv, the small solid in the liquid which the water acts like the media. It is enable to the higher density minerals, salts like and organic materials to suspend in water. The suspension performance is better than of other organic, inorganic materals.
Exchange and adsorption property: It has the cation property of the exchange and adsorption. It reacts with fat amic, and amine salts like materials to the organic chemical materials. It can absorb essence, colouring materials, pigments or enzyme materials to enhance the fargrant and to reduce the drug bitter.
Emulsifying stability: It has the good stable performance for the lactic materials no matter oil contains water or water contains oil. At the same time it has an excellent extension and membrane.
Double compound property: It can increase the density becuase it has compatibility with organic anions which the colloid needs.
Usage: Synthetic aluminium silicate should be used in the dispersed liquid. The solid powder can't be mixed to the other materials directly. Usually we use the content (2~4)% of the dispersed liquid. We have to put the liquid for 24h in the normal temperature or place 2~4h after boiling the liquid. At the same time we would better constantly stir (preferably with high-speed blenders to do it 3000/ hours), and then diluted to the required concentration of industrial products. If the quantity is not large we generally use mineral water bottle, plus some lukewarm water, forceful shaking of a few min.
