Embodiment Construction

[0019] 1. The preparation of the bactericidal algaecide of the present invention: according to the aforementioned preferred mode, it can be prepared as follows: isothiazolinone: 40%; dodecyldimethylbenzyl ammonium chloride: 40%; polyacrylic acid: 20% %. Or other preparation methods included in the scope of the formula of the present invention can also be adopted.

[0020] 2. Use of the bactericidal and algicidal agent of the present invention: according to the aforementioned preferred mode, the bactericidal and algicidal agent with a concentration of 100-600 mg / L can be added, more preferably, the bactericidal and algicidal agent with a concentration of 150-300 mg / L can be added. The above-mentioned bactericidal algaecide, such as using the concentration of 200mg / L to carry out. The dosage of the bactericidal algicide of the present invention can be selected specifically according to the thickness of the slime to be treated and the components of the slime.

Abstract

A bactericiding algicide effective to strip clay contains isothiazolinone, lauryldimethylbenzyl ammonium chloride and polyacrylic acid.

Description

technical field [0001] The invention belongs to the fields of chemical industry and environmental protection, and relates to a bactericide and algicide. Furthermore, the invention relates to a bactericide and algaecide effective for slime stripping in various water systems. Background technique [0002] In the cooling water system, there will often be a large number of microbial growth and reproduction. The large-scale reproduction of microorganisms will cause a large amount of microbial slime in the cooling water system, which will be deposited on the surface of the pipes such as heat exchanger tubes, reducing the cooling effect and greatly Increase the energy consumption of the equipment. Moreover, once a large amount of microbial slime is generated, the water quality of the cooling water will deteriorate rapidly, and the corrosion and scale inhibitors will fail, which will directly endanger production, and even damage equipment and block pipelines. [0003] Therefore, mi...
