Abstract

The application discloses a draught fan dedusting stripping scale inhibitor and a preparation method thereof. The scale inhibitor is prepared from sodium polyacrylate, sodium lauryl sulfate, glycerol, bis-imidazoline, distilled water, cyclohexane, phosphorus trichloride, methyl alcohol, zinc chloride, sodium gluconate and glacial acetic acid, and is simple in operation, poisonless and tasteless, safe and reliable, and can run 1 to 3 months without scaling; the use amount of the scale inhibitor is less, only 0.5 to 2.5 mg / L, and the cost is saved; the effect is lasting, the scale inhibitor can be stored for one month at the temperature of 40 to 60 DEG C, and the scale inhibiting ratio is 97 to 100 percent.

Description

technical field [0001] The application belongs to the field of environmental protection reagent technology, and in particular relates to an environmental protection agent with good corrosion inhibition performance for blower dust removal and scaling inhibitor and a preparation method thereof. Background technique [0002] Scale inhibitor: It is a kind of agent 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 of 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, st...
