Sulfamic Acid Application

Chemical formula: NH2SO3H
Molecular weight：97.09
Status：It is generally a white, odorless orthorhombic flaky crystal, with a relative density of 2.126 and a melting point of 205°C. It is soluble in water and liquid ammonia. At room temperature, as long as it is kept dry and does not contact with water, the solid sulfamic acid does not absorb moisture and is relatively stable. .
Application：Widely used in a variety of industrial equipment and civil cleaning agents for metal and ceramics, sulfonating agents for dyes, medicines and pigment industries, dyeing agents, high-efficiency bleaching agents, fiber, paper flame retardants, softeners, and resin cross-linking accelerators In various fields such as pesticides, herbicides, anti-drying agents and standard analytical reagents.

Description

SULFAMIC ACID
A new invention	A new invention is used to clean scale on stainless steel machinery, which mainly solves the problem that existing cleaning solutions cannot completely clean scale on stainless steel objects or may cause damage to other materials in stainless steel machinery during cleaning. The cleaning solution includes acid solution and passivation agent. The formula of the acid solution, calculated as a percentage of mass concentration, includes: amino sulfonic acid 1.0-10.0, glacial acetic acid 1.0-8.0, corrosion inhibitor 0.1-1.0, water 82.0-97.0, and water temperature between 10 ℃ and 60 ℃; Passivating agents include sodium hydroxide, trisodium phosphate, and water, including sodium hydroxide 0.1, trisodium phosphate 0.05, and water 99.85 in mass concentration percentage
Application	Sulfamic acid cleaning agents have a wide range of applications and can be used to clean boilers, condensers, heat exchangers, jackets, and chemical pipelines. Use it to remove scale from glass lined storage tanks, pots, open beer coolers, and beer barrels in breweries; Clean the evaporator of the enamel factory and the equipment of the paper mill; In terms of air conditioning, it can remove rust and scale from the cooling system and evaporative condenser; It can be used by sea vessels to remove algae and scale from seawater evaporators (distillation equipment), heat exchangers, and brine heaters; Can clean scale from copper kettles, radiators, tableware washing mechanisms, silverware, water closets, ceramic tiles, food and cheese processing equipment; It can remove protein deposits on the digester and deposits on disinfectants used in fresh meat, vegetables, and cheese processing plants. The US Department of Agriculture permits the use of sulfamic acid as an acidic cleaning agent in fresh meat, poultry, rabbits, and egg processing enterprises.
