Abstract

The invention discloses an environment-friendly high-efficiency compound corrosion and scale inhibitor. The environment-friendly high-efficiency compound corrosion and scale inhibitor comprises the following raw materials in parts by weight: 20 to 40 parts of polyepoxysuccinic acid, 15 to 30 parts of lignosulfonic acid, 10 to 15 parts of sodium polyacrylate, 8 to 12 parts of sodium gluconate, 5 to 10 parts of sulfite, 3 to 8 parts of nitrite, 1 to 5 parts of azole derivatives, 1 to 3 parts of a dispersant, 3 to 8 parts of a synergist, and 0.2 to 1 part of a surfactant. The environment-friendly high-efficiency compound corrosion and scale inhibitor has excellent scale inhibition performance, has high environment friendliness, has a very good effect on inhibiting the production of calcium carbonate scale, and has a certain effect on inhibiting the growth of bacteria, and can avoid an eutrophication problem of water quality caused by the emission of phosphorus; the environment pollution is lightened; the multiplication of microbes is reduced.

Description

technical field [0001] The invention relates to a scale inhibitor, in particular to an environment-friendly and efficient composite corrosion and scale inhibitor. Background technique [0002] Scale inhibitors are a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation and scaling of insoluble inorganic salts on metal surfaces, and maintain good heat transfer effects on metal equipment. The anti-corrosion and anti-scaling agent for cold-changing equipment is formulated with epoxy resin and specific amino resin as the base material, adding appropriate amount of various anti-rust, anti-corrosion and other additives, and is a single component. It has excellent shielding, anti-seepage, anti-rust properties, good scale resistance, thermal conductivity, excellent resistance to weak acids, strong alkalis, organic solvents, etc. It has strong adhesion, and the film layer is bright, flexible, dense, and hard. .
