Using sulfamic acid as a cleaning agent, because it is a solid, with storage and transportation is convenient and easy manufacture, and many other advantages, especially for the long haul.
The cleaning agent of the amino sulfonic acid is widely used, and can be used for cleaning the boiler, the condenser, the heat exchanger, the jacket and the chemical pipeline. Lu; cool, remove the air conditioning evaporator in beer factory use it for cleaning glass lined tank, pot, open beer cooler, beer barrel fouling; cleaning enamel factory, and paper mill equipment, etc.; in the cooling system of evaporative condenser of rust and scale; sea going ships use it can remove water evaporator (distillation equipment, heat exchanger and the brine heater in seaweed, scale, can clean the brass, radiator, tableware washing mechanism, silverware, toilet, tiles, food and dairy processing equipment of scale can be cleared by a deposition in the digester protein and meat, vegetables and cheese processing plant used in disinfection of sediments. The United States Department of agriculture to use amino acid in fresh meat, poultry, rabbit, egg processing enterprises for acid cleaning agent.
Injection of amino sulfonic acid into carbonate reservoir. Because the amino sulfonic acid is easy to react with the oil reservoir rock, it can avoid the formation of salt deposition, and the treatment cost is slightly higher than that of the hydrochloric acid, but the oil production is doubled. Potassium acetate 48.5%, amino sulfonic acid, 3.4%, in the United states. Wetting agent 3% – 0.1 of the water solution to clean the oil well casing gypsum scale layer, processing time is about 30 hours
The shell of the car first electroplating tin zinc alloy, then paint, paint film adhesion will increase.
Gold plated or alloy commonly used amino sulfonic acid, gold, silver, gold and silver alloy electroplating solution is containing amino sulfonic acid 60 ~ 170 grams of each litre of water. Typical electroplating silver needle is female clothing each litre of water containing 125 grams of amino acid, can obtain very bright silver surface. Alkaline metal amino sulfonate, amino sulfonic acid ammonium or amino sulfonic acid can be used as conductive and buffering compound in the new water bearing gold plating bath.
When the nickel plating waste liquid is recovered, the resin is washed with the cation exchange resin, and the resin is cleaned by the amino sulfonic acid, and the adsorption desorption is made. Such as electroplating wastewater treatment 400ppmNi, 150 g / L of amino sulfonic acid 50ml and recovery (NH2SO3) 2112 g / L, NiSO4148 g / dl. In the nickel component repair need nickel nickel, in the anode processing available 100 g / L of amino sulfonic acid treatment. With 0.003 to 0.1 moles of amino sulfonic acid cleaning solution in nickel plating nickel plating on the surface of the.
Copper plating of the amino acid content of 3 to 20 liters, the role of amino sulfonic acid is the coating is dense and malleable, the viscosity is high.
Iridium plating when NH2SO3H/Ir is more than or equal to 7, of iridium coating can be obtained without crack, the iridium layer thickness of 15 microns, the big stick relay. The product has automatic anti pollution equipment showed good activity.
In silver, electrical apparatus elements rhodium plating rhenium alloy, electroplating solution containing amino sulfonic acid as 100 g / L, when the coating thickness is less than or equal to 5 um has very high hardness and strong corrosion resistance and electric plating is very bright and beautiful.
In the brass is smooth and beautiful rhodium and rhenium electroplating layer hardness high, corrosion, electroplating solution containing amino sulfonic acid 100 g / L, 50 g / L sulfuric acid, rhodium (such as sulfate) 2 g / L, rhenium (such as 0.05 g / L 2] k3n RuCl4H2O2, in 65 DEG C and 1 ~ 2 ANN / DM 2 conditions, deposition rate of 3 ~ 4 mg / law-abiding.
Italy has been using amino sulfonic acid lead bath instead of fluorine acid bath, can reduce pollution. There are many uses in the anti corrosion aluminum industry. Product luster good, good processing performance.
Amino sulfonic acid is cheap and easy to get and stability of solid acid, the esterification of organic acid has a good catalytic effect, and no corrosion equipment.
