Main use
In the field of cleaning agents: Sulfamic acid water solution can remove scale and corrosion products on the surface of equipment made of materials such as iron, steel, copper and stainless steel. The effect of its water solution on the corrosion products of iron is relatively slow. Some sodium chloride can be added to make it slowly produce hydrochloric acid, thereby effectively dissolving iron scale. It is also the only acid that can be used for cleaning galvanized metal condensers, heat exchangers, jackets, chemical pipelines and galvanized metal surfaces. As a cleaning agent, it is solid and has the advantages of convenient storage and transportation, as well as easy preparation. It is particularly suitable for long-distance use.
In the field of industrial raw materials: It is a raw material for manufacturing synthetic sweeteners, herbicides, flame retardants, preservatives, etc., and can prevent wheat rust disease. In recent years, it has mainly been used in the production of sodium cyclamate cyclosilylsulfonate.
Other industrial fields: Widely used in electroplating industry agents (electrochemical polishing agents), asphalt emulsifiers, etching agents, sulfonating agents for dye, pharmaceutical and pigment industries, dyeing agents, high-efficiency bleaching agents, flame retardants for fibers and paper, softeners, resin crosslinking accelerators, anti-drying agents, and standard analytical reagents, among other fields.
