Common chemical water treatment chemicals

Chemical water treatment agent is mainly through chemical methods of sewage treatment, recycled water, the main categories are: corrosion inhibitors, scale inhibitors, biocides, flocculant.
There are many kinds of inhibitors of aqueous medium (such as chromate, zinc, phosphate, nitrate, silicate and so on). With the improvement of environmental requirements, have been widely used in the cooling water and organic phosphates, such as trigeminal thirty-two amino acid (ATMP), hydroxy ethylidene diphosphonic acid tibia (HEDP), ethylene diamine tetra four phosphonic acid (EDTMP), as well as organophosphates, such as triols phosphate, six yuan alcohol phosphate, copper corrosion inhibitor is dedicated to the benzothiazole sulfur benzene and benzene Benzotriazole. Molybdates and tungstates as a corrosion inhibitor recently started application. Aromatic azoles are corrosion inhibitor for copper and its alloys, primarily benzene benzothiazole sulfur and benzene Benzotriazole. Here are some inhibitors as following:
Copper and silver corrosion inhibitor Benzotriazole (BTA) , 1,2,3 bezotriazole.
It is a kind of white to light yellow needle-like crystals pure product, the melting point of it is 98.5 ℃, boiling point 204 ℃ (15 mm Hg ), it can be slightly soluble in water, soluble in alcohol, benzene, toluene, chloroform and other organic solvents. Copper and silver corrosion inhibitor BTA can be adsorbed on the metal surface to form a thin film to protect copper and other metals from corrosion of air and harmful media. Copper corrosion inhibitor BTA can be used in the circulating cooling water system with a variety of scale agent, biocide. And it has a good corrosion effect in the circulating cool water system. And the amount of it in the circulating cooling water system is 2-4 mg/L. BTA can also be used as anti-discoloration agent-cooper and silver, auto coolant, lubricant additives.
Copper corrosion inhibitor methyl Tolyltriazole (TTA)
It is a kind of white to off-white granules or powder, is a mixture of 4-methyl benzene Benzotriazole and 5-methyl benzene Benzotriazole, the melting point of it is 78-85℃, it is insoluble in water, but can be soluble in alcohol, benzene, toluene, chloroform and other organic solvents, and is also soluble in dilute alkali.
TTA can be used as non-ferrous metals copper corrosion inhibitor of copper and copper alloy corrosion inhibitor for ferrous metals are also corrosion inhibition. TTA copper corrosion inhibitor adsorbed on the metal surface to form a thin film to protect copper and other metals from the atmosphere and water harmful corrosive media. TTA copper corrosion inhibitor film is more uniform, and mercapto benzothiazole (MBT) compound with better results. Copper corrosion inhibitor TTA dissolved with alcohol or alkali added to the circulating water, the water concentration of the product 2-10mg / L, if water system has been severely non-ferrous metal corrosion, 5-10 times the normal concentration can be added to the product to make system quickly passivated.
Perhaps you have found that the price of fine chemical products Benzotriazole has rose slightly. In fact, because of the increasingly serious environmental problems, the price of Benzotriazole growth is the inevitable trend.
