What is scale inhibitor?

Scale inhibitor is a kind of dispersed water insoluble inorganic salt, prevent or interfere with insoluble inorganic salts in the scaling function of metal surface precipitation, node, a class of chemicals and maintenance of metal equipment heat transfer effect is good. Cooling and heat exchanging equipment corrosion inhibitor with epoxy resin and specific amino resin as binder, adding various kinds of antirust, corrosion amount of various additives made from, as a single component. It has excellent shielding, anti permeability, anti rust performance, excellent scale inhibition, thermal conductivity, excellent resistance to acid, alkali, organic solvent properties, its strong adhesion, and the film bright, flexible, compact and hard.
Here are some kinds of scale inhibitors as following:
1. RO scale inhibitor: Reverse osmosis antisludging agent, dispersing agent TH-0100 is a kind of high efficient scale inhibitor, suitable for reverse osmosis (RO) system and nanofiltration (NF) and ultrafiltration (UF) system, which can prevent membrane fouling, can increase the water yield and water quality, reduce operating costs. Reverse osmosis antisludging agent, dispersing agent TH-2000 is a kind of high efficient scale inhibitor, especially suitable for reverse osmosis to barium, strontium content is high, the reverse osmosis system of barium sulfate, strontium sulfate scaling tendency serious. It can range in a wide range of fouling substances effectively prevent fouling. In the reverse osmosis system (RO), nanofiltration system (NF) and ultrafiltration (UF) system, it can be used in reverse osmosis antisludging agent.
2. Specific inhibitors:
1). Sodium Benzotriazole BTA-Na: BTA (Na) can be adsorbed to form a thin film on the surface of metal, copper and other metals from corrosion protection of the atmosphere and harmful medium. BTA(Na) in circulating cooling water system with a variety of scale inhibitor, biocide use, on the circulating cooling water system of inhibitor in circulating water, the dosage is 2 to 4mg/L. BTA(Na) can be used as anti tarnish agent, coolant, lubricant additive copper silver.
2). Sodium Mercaptobenzothiazole (MBT): MBT (Na) can be used as the circulating cooling water system of copper corrosion inhibitor. MBT (Na) inhibition mainly rely on and copper on the surface of activated copper atom or ion to produce a chemical adsorption, or to chelation to form a layer of dense protective film, so that the copper equipment to get good protection, the use of general 4mg/ L, MBT (Na) also can be used as plasticizer, acidic copper plating agent using spectrophotometry.
3). Tolyltriazole (TTA): TTA can be used as corrosion inhibitor for copper and copper alloy nonferrous metal, black metal and inhibition. Adsorption of TTA to form a thin film on the surface of metal, copper and other metals from corrosion protection of air and water of harmful medium. This film is more uniform, and the effect of the combined use of Sodium Mercaptobenzothiazole. TTA with alcohol or alkali dissolving and adding to circulating water, the water of the product concentration was 2 to 10mg/L, if the water system of the nonferrous metal has serious corrosion, can according to the normal concentration of 5 to 10 times add the product in order to make the system quickly passivation.
