Aluminum dihydrogen phosphate binder for lost foam coating

In recent years, lost foam casting has received extensive attention at home and abroad. Compared with traditional casting processes, lost foam casting has unique advantages, low cost, low energy consumption, low environmental pollution, and is suitable for mass production. A structurally complex part.
Coating is one of the key factors for lost foam casting. It not only prevents the casting from sticking sand, but also improves the strength and rigidity of the white mold, ensuring deformation and damage that the white mold does not undergo during flow, shape and filling. When the paint has poor gas permeability, it may cause back spray when pouring. On the one hand, it poses a threat to the safety of workers, on the other hand, it is easy to cause casting defects and increase the difficulty of pouring. Therefore, the lost foam coating has a particularly high requirement for raw materials, and it is difficult for a general binder to function in the middle.

To this end, Zhengzhou Yucai Phosphate Chemical Plant specially went to the customer's factory for sampling and research, and finally developed a high-temperature binder of aluminum dihydrogen phosphate used in the lost foam coating. It can improve the strength of the coating and the high-temperature sintering performance as a whole, and ensure that the strength and rigidity of the coating can be maintained even when the thickness of the coating is reduced.

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)!
