Application of Aluminum Dihydrogen Phosphate in Castables

Castables, also known as refractory castables, are granular and powdery refractories made from refractory materials with a certain amount of binder. They have high fluidity and are shaped by pouring.

Compared with other amorphous refractories, the binder and water content are higher and the fluidity is better. Therefore, the castable has a wide range of applications. The binder of the material used can be selected according to the use conditions. It can be directly poured into the lining and used as the prefabricated block by pouring or compacting.

Castable is one of the most widely used amorphous refractories in recent years. Mainly used to construct various heating furnace lining and other integral structures. At present, not only ordinary amorphous refractories are widely used in heating furnaces, but also light amorphous refractories can be used, and they are developing towards fibers. The application of unshaped refractory fabrics is also developing further.

Aluminum dihydrogen phosphate is a kind of additive often used in the production of castables. Aluminum dihydrogen phosphate has normal condensation and hardening speed at room temperature and should have relatively high strength after hardening. In addition to some chemical reactions with refractories to produce new products, the condensation hardening of aluminium dihydrogen phosphate is mainly due to the formation of macromolecules and aggregates by polymerization and the strong adhesion between them. Aluminum dihydrogen phosphate also has high temperature resistance. Usually the composition of castable requires aggregate, fine powder, binder, and additives, in which aluminium hydrogen phosphate acts as additive.

Already described here will not be repeated, users must pay attention to the quality of aluminium dihydrogen phosphate products when choosing, poor quality products will directly affect the use of the terminal, will cause great losses. Zhengzhou Yucai Phosphate Chemical Plant has a steady supply of 67% aluminum dihydrogen phosphate (solid powder) and 33% aluminum dihydrogen phosphate (liquid) throughout the year.

Zhengzhou Yucai Phosphate Chemical Factory specializes in the production of sodium hexametaphosphate, sodium pyrophosphate, sodium tripolyphosphate, disodium hydrogen phosphate, industrial phosphoric acid, trisodium phosphate, aluminum dihydrogen phosphate, solid aluminum dihydrogen phosphate, liquid dihydrogen phosphate Aluminium, sodium dihydrogen phosphate and other phosphate series products, after more than 30 years of continuous pursuit and development, relying on skilled chemical technology and product development, equipment renewal and established a good cooperation and sharing relationship with many universities, In the chemical industry, we have branded (Yucai Phosphate)!
