Abstract

A disclosed modified water-quality stabilizing agent is prepared from the following raw materials in parts by weight: 90-110 parts of water, 30-50 parts of polyaspartic acid, 5-10 parts of zinc sulfate, 20-35 parts of sodium polyacrylate, 4-12 parts of lignin, 25-35 parts of calcium gluconate, 6-10 parts of polyphosphate, 8-16 parts of sodium molybdate, 11-18 parts of benzotriazol, 15-25 parts of sodium silicate, 3-9 parts of ferrocyanide, 15-20 parts of isopropanol, 8-14 parts of calcium carbonate and 15-25 parts of glycol. The provided modified water-quality stabilizing agent is environment-friendly, less in usage amount, excellent in scale-inhibiting rust-inhibiting performances, and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of stabilizers, in particular to an improved water quality stabilizer. Background technique [0002] Scaling and corrosion are ubiquitous issues in circulating cooling water systems, which seriously affect the economic benefits of products. Dirt and corrosion problems. Chemicals added to circulating cooling water to prevent cooling water from corroding and scaling equipment. It can form a stable complex with calcium, magnesium ions and other scale-forming substances in water. It is easily soluble in water and plays a good role in chelation, dispersion and corrosion inhibition, preventing scaling and loosening the old scale layer, which is easy to clean dirt. It has good corrosion and scale inhibition effects on carbon steel and stainless steel, can improve the heat exchange effect of equipment, prolong the service life of equipment, and play the role of saving water, energy and steel. At present, water t...
