aluminum dihydrogen tripolyphosphate Use and Manufacturing

Methods of Manufacturing

Alumina method. Reaction equation: Al2O3+6H3PO4→2AlH2P3O10+7H2O Method of operation: Mix α-alumina and phosphoric acid with a molar ratio of R=0.5~0.2. It is heated to 100-200°C with a slight fire for dehydration to produce the first product. This product is heated in an atmosphere with a high water vapor pressure for 3 to 24 hours in an electric kettle at 300 to 350°C to carry out a polymerization reaction to produce aluminum dihydrogen tripolyphosphate. After cooling, the finished product of aluminum dihydrogen tripolyphosphate is obtained.

Uses

It is a pollution-free white anti-rust pigment. Widely used in oil pipelines, bridges, railways, ships, vehicles, chemical equipment and interior and exterior wall coatings in the construction industry. It has good effect in refrigerator primer and latex paint for construction. Also used as catalyst, water glass hardener, adsorption deodorant.
