What is the main bonding mechanism of sodium hexametaphosphate?

1. sodium hexametaphosphate is viscose after absorbing water, which is closely related to the nature of sodium hexametaphosphate itself. The molecular formula of sodium hexametaphosphate is (NaPO3) 6, which belongs to a polyphosphate with uncertain composition. The anion of sodium hexametaphosphate has a high molecular weight. Generally, it contains as many as 30-90 PO3 genes and forms a long chain.

2. Because of the addition of sodium silicate and other alkaline substances, the alkaline environment with PH value of 10-10.5 was prepared. That is, the concentration of OH-ion in the coating is high and the reaction proceeds to the right, which is helpful to the further decomposition of H3PO4. The research on talent cultivation and chemical industry also promotes the conversion of sodium hexametaphosphate to orthophosphate. At this time, the phosphate will condensate several phosphate functional groups, especially the sodium hexametaphosphate molecular group will condensate at high temperature. After condensation, the molecular group will be combined with the three-dimensional network of bentonite molecular group in the paint, which plays an effective role in bonding.
