Sulfamic Acid

1. Cleaning agent

Metal and ceramic equipment cleaning: Sulfamic acid can be used as a cleaning agent to efficiently remove rust, oxides, oil stains and other impurities on the surface of metal and ceramic equipment. It is widely used in the cleaning of boilers, condensers, heat exchangers, jackets and chemical pipelines to ensure the cleanliness and normal operation of the equipment.

Fine cleaning: In the food industry, sulfamic acid is also used as an equipment cleaning agent to ensure the hygiene and safety of food processing equipment.

2. Bleaching aid

Papermaking industry: In the process of papermaking and pulp bleaching, sulfamic acid can be used as a bleaching aid. It can reduce or eliminate the catalytic effect of heavy metal ions in the bleaching liquid, ensure the quality of the bleaching liquid, and at the same time reduce the oxidative degradation of metal ions on fibers, and improve the strength and whiteness of pulp.

3. Dye and pigment industry

Eliminate and fixative: In the dye industry, sulfamic acid can be used as an eliminator of excess nitrite in diazotization reaction, and a fixative for textile dyeing. It helps to improve the stability and dyeing effect of dyes.

4. Textile Industry

Fireproofing and Additives: Sulfamic acid can form a fireproof layer on textiles to improve the fireproof performance of textiles. At the same time, it is also used in the manufacture of yarn cleaning agents and other additives in the textile industry.

5. Electroplating and Metal Surface Treatment

Electroplating additives: In the electroplating industry, sulfamic acid is often used as an additive to the electroplating solution. It can improve the quality of the coating, make the coating fine and ductile, and increase the brightness of the coating.

Metal surface pretreatment: Before electroplating or coating, sulfamic acid can be used for pretreatment of metal surfaces to remove surface oxides and dirt and improve the adhesion of electroplating or coating.

6. Chemical Synthesis and Analysis

Chemical Synthesis: Sulfamic acid is an important raw material for the manufacture of synthetic sweeteners (such as acesulfame potassium, sodium cyclamate, etc.), herbicides, fire retardants, preservatives, etc. It also has the function of a sulfonating agent and plays a catalytic role in organic synthesis reactions.

Analytical reagents: Sulfamic acid products with a purity of more than 99.9% can be used as standard acid solutions when performing alkaline titration. At the same time, it is also used in various analytical chemical methods such as chromatography. VII.

7. Other applications

Petroleum industry: Sulfamic acid can be used in the petroleum industry to remove blockages in oil layers and increase the permeability of oil layers. It easily reacts with oil layer rocks to avoid the deposition of salts generated by the reaction, thereby increasing oil production.

Water treatment: In the field of water treatment, sulfamic acid can be used as a scale inhibitor and corrosion inhibitor to inhibit the formation of scale layers in water and protect equipment from corrosion.

Environmental protection field: Sulfamic acid is also used in the field of environmental protection, such as for degrading nitrites in aquaculture water and reducing the pH value of water bodies.
