Embodiment Construction

[0006] The composition of the composite water treatment agent formula of the present invention includes acrylic acid-2-acrylamide-2-methylpropanesulfonic acid multi-polymer, phosphine carboxylic acid, hydroxyethylidene diphosphonic acid, zinc salt and water; each component in the formula The weight percent is acrylic acid-2-acrylamide-2-methylpropanesulfonic acid multi-polymer 10~40%, phosphine carboxylic acid 20~30%, hydroxyethylidene diphosphonic acid 15~30%, zinc salt 5~ 10%, water 30-80%. The above-mentioned substances are mixed in proportion to prepare the water treatment agent. This formula is a low-phosphorus and environmentally friendly formula. The hydroxyethylidene diphosphonic acid and phosphonic acid in the formula have high-efficiency scale inhibition performance. Through the "solubility limit" effect of the chemical, the calcium hardness is stabilized, and the supersaturation of calcium ions and carbonate groups in water is increased. degree, and change the norm...

Abstract

The invention discloses a composite water treatment medicine, which comprises the compositions of acrylic acid-2-acrylamido-2-methylpropane sulfonic acid copolymer, phosphono-carboxylic acid, 1-hydroxy ethylidene-1,1-diphosphonic acid, zinc salt and water; and the compositions are mixed according to the proportion to prepare the water treatment medicine. The medicine has excellent effect of scale and corrosion inhibition on treating high-strength and high-hardness water so as to ensure that the corrosion rate and the scale deposit velocity of the treated water are both lower than the control index of recirculated water quality monitoring, and is incomparable with other water treatment medicines in aspects of prolonging service life and repair cycle of equipment, ensuring long-term safe operation of the equipment, saving steel materials and water, reducing environmental pollution and the like. The water treatment medicine is applied to an industrial cooling water circulating system, and has great economic and social benefit and good popularization value.

Description

1. Technical field [0001] The invention relates to an industrial cooling water treatment agent, in particular to a composite water treatment agent with high hardness and high alkalinity. 2. Background technology [0002] In most parts of northern my country, natural water is a kind of high-strength, high-alkalinity water quality with serious scaling characteristics. When this kind of water is used as a cooling medium in the industrial cooling circulating water system, the water quality will deteriorate, corrosion, Scaling and other problems lead to blockage or leakage of heat exchangers and pipes, seriously affecting the normal operation of production equipment. In recent years, with the rapid development of social economy and technological progress, water treatment technology has been paid more and more attention. People have developed various water treatment chemicals to treat industrial cooling water, but for composite water with high strength and high alkalinity The trea...
