In early December 2016, the newly invested factory was reopened in Nanpu Economic Development Zone, Caofeidian District, Tangshan City.
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 honest style, rigorous work attitude, and production philosophy of excellence, and continues to grow and develop. In 2002 and 2004, Laizhou Sanding Chemical Co., Ltd. and Yantai Sanding Chemical Co., Ltd. were established successively and have a rich product line. The current products mainly include ammonium sulfamate, guanidine sulfamate, sulfamate, guanidine hydrochloride, liquid guanidine hydrochloride and related products. Widely used in food additives, textile printing and dyeing auxiliaries, pesticide intermediates, pharmaceutical intermediates, flame retardant treatments, etc. We always adhere to the business philosophy of "No Best, Only Better", provide customers with high-quality products and services, rely on mature and advanced technology and perfect sales concepts to gain a foothold in the fierce market competition. The products have been sold to more than 50 countries and regions in the world, with stable channels and high customer awareness.
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.
The sulfamic acid cleaning is selected as the cleaning agent, and the static small-scale test is first carried out. 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.
