Sell Sodium Pyrophosphate

Description

Appearance: white powder or crystal Physical and chemical properties White powder or crystal. Relative density 2.**4, melting point **0 ℃, boiling point *3.8 ℃, the proportion of 2.**4. Colorless and transparent crystal or white crystalline powder. Soluble in water, *0 ℃, when the water solubility of **0g for 6.*3, its aqueous solution is alkaline; not soluble in alcohol. Aqueous solution at *0 ℃, the following is still stable, boil the hydrolysis of disodium hydrogen phosphate. In dry air, weathering, lose crystal water at **0 ℃. Easily absorb moisture in the air and deliquescence. And alkaline earth metal ions can generate complex; encounter with Ag + pyrophosphate generated white silver. Uses: electroplating industry for the preparation of plating bath, and allowing the formation of iron-DOP. Wool and wool textile industry as a degreasing agent and hair bleaching agent. Paper industry for bleaching paper and plant fibers. Printing and dyeing industry as dyeing, bleaching fine when the additive. Japanese chemical industry as a toothpaste additive with the DCP and to play a stabilizing effect on the formation of colloid can be used for production of synthetic detergent and shampoo ointment products. Water as a water softener. Machining as rust agent. Chemical production used as dispersants and emulsifiers. Can also be used for water treatment agent, oil drilling, etc., in the food industry as a quality improver, emulsifier, buffer, chelating agent and so on. Skype:zjyhappy***0 MSN:*****
