Abstract

The invention discloses a composite scale-inhibiting corrosion-inhibiting bactericide and a preparation method thereof. The bactericide is prepared from the following raw materials in parts by weight:10-20 parts of alcohol, 20-40 parts of quaternary ammonium salt, 10-20 parts of organic sulfide, 5-10 parts of phosphonic acid salt, 5-13 parts of polymer, 5-10 parts of chlorophenol, and 10-30 partsof deionized water. The preparation method comprises the following steps: adding soft water into a reaction vessel by a pump according to metering, adding methanol or ethanol into the reaction vessel, and adding the quaternary ammonium salt, the phosphonic acid salt, the polymer, the organic sulfide, and the chlorophenol into the reaction vessel sequentially, and stirring respectively when each of the products is added; and stirring for another 30 minutes after addition of the raw materials is completed, so as to obtain a finished product. According to the composite scale-inhibiting corrosion-inhibiting bactericide and the preparation method thereof, the components have very high complementarity, synergy and compatibility, so that the medicament has excellent performance, and can effectively prevent the formation of calcium carbonate scale, calcium sulfate scale and calcium silicate scale in water; and under a medicament adding concentration of 50-100 ppm, a protective film can be formed on a tube wall, so that corrosion of equipment and piping is prevented.

Description

technical field [0001] The invention relates to water treatment technology in the field of chemistry, in particular to a composite antiscaling and corrosion inhibiting bactericide for circulating water integrating scale inhibition, corrosion inhibition and sterilization and a preparation method thereof. Background technique [0002] Water is the source of life, an irreplaceable resource for human survival and development, and the basis for sustainable economic and social development. my country's industrial water accounts for more than 70% of urban water use, industrial cooling water accounts for 80-90% of industrial water use, and the utilization rate of industrial reuse water only accounts for 20-30%, which is 1 / 3 of developed countries. Therefore, it is imperative to strengthen the operation and management of industrial circulating cooling water. [0003] During the operation of industrial circulating cooling water, due to the circulating evaporation of cooling water, th...
