Amino sulfonic acid USES explanation

　　Amino sulfonic acid is the important chemical products, is widely applied in the metal and ceramic manufacturing various industrial equipment and civil cleaner, oil and treatment and cleaner, plating industry by using electrochemical polishing agent, asphalt emulsifier, etching, dyes and pigments in pharmaceutical industry, dyeing sulphonated with agent, fiber, paper bleaching, efficient with flame retardants, softener, resin crosslinking agent, herbicide resistance, promote withered and standard analytical reagents etc. Specific purpose is as follows:

　　1 detergent　Amino sulfonic acid alkali metal salts of good solubility, it and calcium, magnesium chemical compounds such as function is very fierce. In the cleaning process using sulfamie acid as the main raw materials cleaner, in an hour there will be 90% of calcium, magnesium compounds into soluble amino sulfonic acid salts, and release co2. It can be used for cleaning boiler, condenser, heat exchanger, jacket and the chemical pipeline. At brewery it can be used in cleaning glass tank lining, pan, open beer cooler, beer kegs of dirt, and the paper mill equipment; In the air conditioning cooling system, It can remove the rust, scale evaporation condenser. seawater evaporator (distil), heat exchanger and salt water heater; the seaweed, scale within What are these patterns, radiator, can clean tableware wash mechanism, silver, toilet, ceramic tile, food and milk and cool processing equipment of scale, It can remove deposition in cooking on protein and meat, vegetables and cheese factory in the use of disinfection sediments. The United States department of agriculture allowed it used in meat, poultry, eggs, rabbit on processing enterprise acidic detergent.

　　Amino sulfonic acid as cleaning, because it is a solid, storage, transportation convenience, easy preparation etc many advantages, especially for your use.

　　2 oil well, increase with oil production will be amino sulfonic acid solution　　Instill it in carbonate reservoir. Amino sulfonic acid can react with reservoir rocks easily, there can avoid reaction of salt, but the costs in processing slightly higher than the hydrochloric acid, oil production.

　　3 Electro-plating　Gold-plated or alloy generally adopted amino sulfonic acid, plating silver, gold and silver alloy plating solution - per liter is made in contain amino sulfonic acid 60 ~ 170 grams. Silver plating solution is typical of each set premium contains amino sulfonic acid 125 grams, can obtain very bright silver plated surface. In a new aqueous gold-plated electric plating amino acid alkali salt, amino-sulfonic acid (or amino sulfonic acid can be used as a cushion, the conductive compound use. Nickel plating liquid recovered from when using d001-cc cation resin absorption is followed by amino sulfonic acid cleaning with resin, make the adsorption and desorption regenerative resin. Cu-plating solution of amino sulfonic acid content for 3 ~ 20 litres, amino-sulfonic acid is fine and rich that coating, the viscosity of force high malleability. Italy has been using sulfamie acid lead bath, can replace fluorine sour bath to reduce pollution. Corrosion prevention in aluminum industry has many USES. Good luster, processing products with excellent performance.

　　4 Etching　Etching the composition of the solution, amino-sulfonic acid salt ions 0.3 ~ 3.0 mole fraction/litre, Cu + 20.3-3.0 mole fraction, NH + / - 41 molecular/litre. Dissolve in the alkaline solution of copper, amino-sulfonic acid etch can accelerate Cu etching. This solution is used to print circuit board production, can selectively corrode copper, and can improve the quality of etching.

　　5 Electrochemical polishing　amino sulfonic acid for 1 - VT3 titanium, VT20 electrochemical polishing dosage for 65-70 grams/litre, can make the titanium alloy surface brightness increases.

　　6 Asphalt emulsion　tearic acid ethyl ester evenly dispersed two leaven in 1800 grams of melting bitumen, add 120 grams and 12 grams amino sulfonic acid formed in the emulsified bitumen in highway construction, it is easy to aggregate sticky relay, strong characteristic.

　　7 Analysis reagent and dyeing auxiliaries NH2SO3H+HNO2→H2SO4+N2+H2O  　The reaction at room temperature can quickly when, can be used for analysis of nitrite in very rare, actually the acidic solution (pH = 2) minutes to complete in reaction to remove excess after dyeing of nitrite. The reaction of urea and nitrite than react more fully and quickly.

　　8 Bleach stabilizers　amino sulfonic acid chloride compound in the water, forming a meal of chlorine free more stable compounds (CIN - HSO3), use this property can be used in the swimming pool water disinfection. Use (HSO3 CIN - mixture can make the durability of disinfection, and can be used for bleaching pulp fibers, the papermaking, the bleaching.

　　9 herbicide resistance, dry agent　amino sulfonic acid &its can make use of the herbicide. Not only the weed control effect is good, in addition to the animal and human health threats, and not in the soil will not long term residual soil pollution. Du pont Ammate sales of goods on amino sulfonic acid of ammonia or tree of filling agent with tree withered.

　　10 The flame retardants　amino sulfonic acid usually when heated can be decomposed into lots of ammonia nitrogen, and has not only cannot harm, flame retardant effect by processing the organization, on the exterior of any change, no paper and fiber can play the role of the softening.

　　11 resin with crosslinking accelerator　Amino sulfonic acid and ammonium salt all in use can resin condensation can promote function of crosslinking agent. When inject thermoplastic resin molding powders added by 0.1 ~ 2.0 amino sulfonic acid, aging resistance, no change can shorten the time of molding resin.

　　12 Sulphonated agent　Amino sulfonic acid as sulphonated agent is widely used in organic synthesis reactions, and it was easy to generate heat with alcohol dimethyl sulfate and ammonia. With phenol, naphthalene distribution can be generated when the response of phenol sulfonic acid, ammonium naphthalenol. With other polymers (such as fat polyacrylamide (etc), water-soluble compounds made easier. These compounds can be used as saturated soil, dyeing auxiliaries used, etc.
