How much sodium hexametaphosphate can be added to the titanium dioxide to make it best?

Titanium dioxide ( TiO2 ) is an important inorganic chemical product, which has important applications in coatings, printing ink, papermaking, plastic rubber, chemical fiber, ceramics and other industries. Titanium dioxide ( English name: titanium dioxide ) is a white pigment mainly composed of titanium dioxide ( TiO2 ). The scientific name is titanium dioxide, and the molecular formula is TiO2. TiO 2 is a polycrystalline compound with regularly arranged particles and a lattice structure. The relative density of titanium dioxide is the smallest. There are two production processes of titanium dioxide: sulfuric acid process and chlorination process.

The main application fields of titanium dioxide are coating, plastic, printing ink and papermaking, with coating accounting for 60%, plastic accounting for 20% and papermaking accounting for 14%, and other fields ( including cosmetics, chemical fiber, electronics, ceramics, enamel, welding rod, alloy, glass and other fields ) accounting for 6%.
