Abstract

The invention discloses an anti-scale inhibitor for treating industrial circulating water and relates to the technical field of industrial circulating water treatment. The anti-scale inhibitor comprises the following components by weight percent: 1.0-2.0% of crylic acid-crylic acid hydroxypropyl acrylate, 0.5-1.5% of ethylene-ethyl acrylate copolymer, 0.1-0.5% of DETPMP, 50-60% of 1-Boc-3-methylamino pyrrolidine, 0.1-0.5% of PBTCA, 0.1-0.5% of ATMP, 0.03-0.4% of HEDP, 0.3-1.0% of sodium nitrite, 0.5-2.0% of acetaldehyde, 14-16% of cyclohexane and 25% of deionized water. The dosing is reasonable; the preparation process is simple; the product is easy to dissolve oxygen; the oxygenation in water can be prevented; the anti-scale inhibitor is low in phosphorus content and excellent in biodegradability and can be compounded with various salt inhibiters.

Description

technical field [0001] The invention belongs to the field of chemical reagents, in particular to a scale and corrosion inhibitor used for industrial circulating water treatment. Background technique [0002] Industrial circulating water treatment is the process of removing some substances harmful to production and life in water through physical and chemical methods. Conditioning process. Industrial circulating water treatment methods are mainly divided into physical treatment and chemical treatment. Physical treatment technologies mainly include: magnetic treatment, electrostatic treatment, photochemical treatment, ultrasonic treatment, etc. Physical treatment technology has the advantages of simple operation, low operating cost, non-toxic and non-polluting. This method is suitable for water with low hardness, but the water treatment effect of complex water with high hardness in my country is not satisfactory. [0003] Chemical treatment technology usually adds a certain ...
