Aluminum tripolyphosphate is a white pigment with excellent anti-rust properties

 

1. Usage:

Aluminum tripolyphosphate, AlH2P3O10·2H2O is a white powder, hardly soluble in water, non-volatile, and its relative density is 3.0-3.1.

Weakly acidic, with a PK value of 1.5-1.6. Compared with other solid acids, the acidity is extremely high (by mass), and there are many active groups per unit mass, so a small amount can produce an effective anti-rust effect. ...

Aluminum tripolyphosphate can emit tripolyphosphate ions (P3O10 5-) with strong complexing ability, and has high complexing ability for divalent and trivalent iron ions, so that a dense passivation film is formed on the surface of the iron substrate In addition, two hydrogen atoms in AlH2P3O10·2H2O are weakly acidic and can combine with metal to form a hard protective film.

 

2. Applications:

As a new type of non-toxic anti-rust pigment, aluminum tripolyphosphate not only has the characteristics of good water resistance and strong corrosion resistance, but also can enhance the properties of flame retardancy, shock absorption, compression resistance and wear resistance, so it is widely used in Anti-corrosion coatings made of different resins for the protection of metal sheets are the most promising anti-rust pigments at present..
