Laizhou Sanding Chemical Co., Ltd. and Yantai Sanding Chemical Co., Ltd. were established successively in 2002 and 2004
The items include sulfamic acid concentration, temperature, time, corrosion inhibitors and additives. Then, on the basis of the static small-scale test, a dynamic simulation test is performed to simulate the process of pickling, washing, neutralization, passivation and so on.
There is a certain technical difficulty in cleaning the complex and insoluble scale, and the key is to choose an appropriate cleaning agent. Sulfamic acid is a good chemical cleaning agent, which can dissolve various scales that are difficult to dissolve with hydrochloric acid under normal conditions.
Cleaning effect inspection and evaluation of cooling system pipes, various parts of the cooling tower and the plastic multi-faceted hollow spherical packing inside the cooling tower, cleaned, no residual scale, no overwashing. The cleaning effect is good.
Public announcement of the environmental protection acceptance report for the completion of the project of Tangshan Sanding Chemical Co., Ltd. with an annual output of 2,000 tons of ammonium sulfamate, 1,500 tons of guanidine sulfamate
Committed to the deep processing of sulfamic acid and the production, development and sales of other new products. The company introduces international advanced technology and equipment, with an honest style, a rigorous work attitude, and a production philosophy of excellence, it continues to grow and develop
