Uses:
1. Application in ceramic:
Reduces the viscosity of the mud, to improve the fluidity of the mud, reducing the rate of mud aqueous. Our ceramic grade STPP dedicated stpp for ceramic slurry, especially the ceramic glaze peptization effect relative to other stpp or ceramic thinner, It has the amount less, impurities lower, the peptization better, more stable quality features.
2. Application in detergent:
Used as an additive synthetic detergent, soap, oil soap synergist and prevent precipitation and articles from the frost. Having strong emulsification for oil and fat, it can be used to adjust the PH value of buffer soap.
3. Other application:
Used in water softener; tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspension solutions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.; As an oil contamination resistance agent in paper production.
