Application of STPP Chemical 94%
STPP Detergent Grade
Stpp can play good chelation on heavy metal ions and remove the heavy metal ions in water. Meanwhile, it can also capture the various metal components contained in dirt and make dissolve during washing. As an igorganic surfactant and metal compound agent, sodium triphosphate has a strong emulsification effect on dirt and can buffer the ph of aqueous solution, which is beneficial to the removal of acidic dirt. In addition, it has the effect of preventing caking to detergent powder.
STPP Food Grade
In food processing industry, stpp can be used as quality improvers and water retention agents in canning, juice drinks, dairy products, soy milk and other food. In addition, it can also be used as softener and thickener, such as, tenderizing canned ham and softening the bean hull in canned beans.
STPP For Water Treatment
STPP can be used as scale inhibitor in cooling water treatment, water softener for industrial water, soap booster and prevent soap grease precipitation and frosting at the same time. It has a strong emulsification effect on lubricating oil and fat. Besides, Chemate STPP (sodium tripolyphosphate) can be used to adjust the PH value of buffer soap.
More Industrial Uses
It can also be used as tanning agent, dyeing assistant and used as dispersant in the preparation of suspensions in industries, such as, paints, kaolin, magnesia and calcium carbonate, as well as drilling dispersant and anti-oil agent in paper production industry.
