Abstract

The invention discloses a compounded scale-inhibiting sustained-release microbicide. The compounded scale-inhibiting sustained-release microbicide comprises the following raw materials in parts by weight: 20-30 parts of dodecyl dimethyl benzyl ammonium chloride, 15-20 parts of 5,5-dichloro-2,2-dihydroxyldiphenylmethane, 5-10 parts of dithiocyano-methane, 1-5 parts of polymaleic acid, 1-5 parts ofphosphino-carboxylic acid-PBTC, 10-20 parts of ethanol, 5-15 parts of dimethylformamide and 80-100 parts of softened water. According to the compounded scale-inhibiting sustained-release microbicide disclosed by the invention, the formula is reasonable in design, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a composite anti-scaling and slow-release bactericide. Background technique [0002] The antiscaling and slow-release fungicide is mainly suitable for various industrial circulating cooling water systems such as medicine, chemical industry, chemical fertilizer, brewing, oil refining, etc. and oil field reinjection water treatment. Circulating water with high chloride ion content and high soluble solid solution content. However, the existing scale-inhibiting and slow-release fungicides have unreasonable formula design and poor application effect. Therefore, there is an urgent need for those skilled in the art to develop a composite anti-scaling and slow-release bactericide. Contents of the invention [0003] The object of the present invention is to provide a composite anti-scaling and slow-release bactericide in order to solve the above-mentioned deficiencies in the p...
