Product description:
Properties: white powder, melting point 622 ℃, soluble in water, calcium and magnesium and other metal ions chelating capacity significantly, can soften hard water to make suspension into solution, there is a weak alkaline, non-corrosive, is a inorganic surface active agent, to have a strong oil and fat emulsification.
Sodium tripolyphosphate have I type (high type) and II (low temperature type) two kinds of crystal morphology, chemical properties of the two the same, difference is that thermal stability and moisture-I than type II, while both the solubility, hydration heat when dissolving are different.
Uses: used as a detergent additive product can also be used in petroleum, metallurgy, mining, papermaking, water treatment and so on. Mainly used as synthetic detergent additive, used in soap synergist and prevent precipitation of soap and grease from frost. Of oil and fat has a strong emulsification can be used to adjust the PH value of the buffer liquid soap. Industrial water softener. --- Tanning agent. Dyeing auxiliaries. Paint, kaolin, magnesium oxide, calcium carbonate and other industries, when suspended in the preparation of dispersant. Drilling mud dispersants. Paper industry as anti-oil agents. In the food industry for the canned food, juice drinks, dairy products, soy milk and other quality improver, mainly for tenderizing canned ham, broad beans, canned convinces Yuba softening can also be used as a softener and thickening agent
