Problems solved by technology

At present, most of the cooling water treatment agents used in open systems are phosphorus-based formulas, but the discharge of phosphorus will cause eutrophication in the surrounding waters, promote the excessive reproduction of microorganisms, especially algae, and cause lake water splashes, seawater red tides and other hazards

Abstract

The present invention discloses a phosphorus-free, green and environment-friendly slow-release scale inhibitor, which comprises the following raw materials in weight part: 5-20 parts of maleamic acid, 5-10 parts of chitosan, 2-5 parts of lignin, 1-10 parts of starch, 3-15 parts of sodium humate, 1-3 parts of polyacrylic acid, 2-10 parts of sodium molybdate, 1-5 parts of zine stearate, 4-10 parts of zinc borate, 3-12 parts of sodium lactate, 1-8 parts of triethanolamine, 3-10 parts of benzotriazol, 5-20 parts of polyaspartic acid, 3-12 parts of S-CETSA, 10-25 parts of polyepoxysuccinic acid, 2-15 parts of acrylic acid-2-acrylamide-2-methyl propane sulfonic acid copolymer and 50-70 parts of water. The phosphorus-free, green and environment-friendly slow-release scale inhibitor is phosphorus-free, non-toxic, green, environmentally-friendly, and good in scale-inhibition and slow-release effect.

Description

technical field [0001] The invention relates to the technical field of scale inhibitors, in particular to a phosphorus-free green and environment-friendly slow-release scale inhibitor. Background technique [0002] An antiscalant is a chemical agent that prevents scale from forming or inhibits its deposition and growth. At present, most of the cooling water treatment agents used in open systems are phosphorus-based formulas, but the discharge of phosphorus will cause eutrophication in the surrounding waters, promote the excessive reproduction of microorganisms, especially algae, and cause lake water splashes, seawater red tides and other hazards. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a non-phosphorous, green and environmentally friendly slow-release scale inhibitor, which is non-phosphorous, non-toxic, green and environmentally friendly, and has good scale inhibition and slow-relea...
