Embodiment Construction

[0014] The present invention is a scale inhibitor and dispersant in a water treatment system. The dispersant is composed of hydroxymethyl methacrylate, diacyl peroxide, acrylic acid-hydroxypropyl acrylate-AMPS copolymer, and maleic anhydride-acrylic acid copolymer. It is composed of compound, zinc chloride and water, wherein the weight percentage of each component is as follows:

[0015] Hydroxymethyl methacrylate, 10%-15%,

[0016] Diacyl peroxide: 10%-15%,

[0017] Acrylic acid-hydroxypropyl acrylate-AMPS copolymer: 30%-40%,

[0018] Maleic anhydride-acrylic acid copolymer: 10%-15%,

[0019] Zinc chloride: 3% to 4%,

[0020] Water: 25% to 35%.

[0021] When the scale inhibitor dispersant in the water treatment system of the present invention is used as a dispersant for ferric oxide during pre-filming, the dosage is (80-100) mg / L. The normal dosage is (10-30) mg / L, and the applicable pH condition is 7.0-9.5.

Abstract

The invention provides an anti-scaling disperser for water treatment systems, which comprises methyl methacrylate, diacyl hydroperoxide, acrylic acid-2-hydroxypropyl acrylate-AMPS copolymer, maleic anhydride-acrylic acid copolymer, zinc chloride and water, the disperser is fire resistant, it is a stramineus or colorless transparent liquid soluble with water, it possesses the capability of dispersing hydroxide of Fe and Zn, and calcium phosphate in alkaline water solutions, and because the disperser has sulfonic groups, so it has good anti-scaling and dispersing action to calcium carbonate.

Description

Technical field: [0001] The invention relates to a scale inhibitor and dispersant used in a water treatment system, in particular to a scale inhibitor and dispersant used in the daily operation of central air conditioning circulating cooling water and industrial circulating cooling water systems. Background technique: [0002] In central air conditioning circulating cooling water and industrial circulating cooling water systems, due to the constant changes in water temperature and pressure, metal ions such as chloride ions, calcium ions, and iron ions in the water are concentrated with the continuous reuse of water, which is easy to produce inorganic The formation of salt scale and inorganic salt scale will reduce the heat transfer effect of the water system. Foreign countries have used separation technology to remove inorganic salt scale, but due to complex operations, they have not been widely used. The existing water treatment agent formulations have developed from chromium-ba...
