Application Of 1h-Benzotriazole
1. Benzotriazole is mainly used as water treatment agent, metal rust inhibitor and corrosion inhibitor. Benzotriazole is one of the most effective corrosion inhibitors for copper and copper alloys in the cooling water system. It is widely used in circulating water treatment agent, antirust oil and lipid products, as well as vapor phase corrosion inhibitor and lubricating oil additive for copper and copper alloy. It is used to purify silver, copper and zinc on the surface in electroplating and has the function of preventing discoloration.
2. It can be used in extreme pressure industrial gear oil, hyperbolic gear oil, anti-wear hydraulic oil, oil film bearing oil, grease and other lubricating grease, as antirust and vapor phase inhibitor. It can be used in antirust oil (grease) products, and is mostly used in copper and copper alloy vapor phase inhibitor circulating water treatment agent, automobile antifreeze, photographic antifogging agent, polymer stabilizer, plant growth regulator, lubricating oil additive, ultraviolet absorber, etc. This product can also be used with a variety of scale inhibitors, bactericides and algaecides.
3. It is widely used for corrosion inhibition and rust prevention of copper and silver equipment. It can also be used for preparing photographic anti dust, anti fog agent and vapor phase rust inhibitor.
4. It is used to purify silver, copper and zinc on the surface in electroplating and has the function of preventing discoloration. Benzotriazole (BTA) and copper atoms form covalent bonds and coordination bonds, which are replaced by each other to form chain polymers, forming multi-layer protective films on the copper surface, so that the copper surface does not have redox reaction, hydrogen and corrosion protection. It also has the same effect on lead, cast iron, nickel, zinc and other metal materials. BTA can be combined with a variety of corrosion inhibitors to improve the corrosion inhibition effect. It can also be used in combination with a variety of scale inhibitors, bactericidal and algal killing agents, especially for the enclosed circulating cooling water system. BTA can volatilize the protective material in the antifreeze glycol for automobiles, in water and in paint. BTA is a good ultraviolet light absorber, and products sensitive to ultraviolet light can play a stable role, for example, to prevent the fading of diazo dyes. Using BTA to treat paper, woven fabric, film, metal coins and other thin products can prevent discoloration. In the process of machining, adding BTA to grinding oil and cutting oil can make the processed copper parts not discolor. It can also be used as an analytical reagent in combination with water and diamine tetraacetic acid, and can be used for the selective determination of silver, copper and zinc. It can also be used as anti fogging agent for photography and organic synthesis intermediate. 5. It is used as an analytical reagent, a photographic antifogging agent, and also for organic synthesis
6. Lubricant additives; Metal deactivator; Extreme pressure agent, bacteria and oxidation inhibitor, used as antioxidant in internal combustion engine oil
