2. Sodium Tripolyphosphate Application
It is mainly used for synthetic detergent as additive, soap synergist and preventing soap grease from separating out and blooming. There is a strong emulsifying effect on lubricating oil, oil fat and can be used to adjust the PH value of buffer soap solution. What’s more, it is used as dispersant when preparing suspensions in industries, such as industrial water softener, tanning pretanning agent, dyeing assistant, paint, kaolin, magnesium oxide, calcium carbonate, etc. It is used as dispersant for drilling mud and as anti-oil agent in paper industry.
