Problems solved by technology

The disadvantage is that most of them are poisonous, can produce secondary pollution, cause serious corrosion to equipment, some have high energy consumption, the medicament is unstable and easy to explode, and some are inconvenient to use
The other is non-oxidative biocidal algicides, such as phenols, aldehydes, amines, quaternary ammonium salts, organosulfur compounds, organophosphorus compounds, and isothiazolones. Reasonable compounding can play a coordinating role through the complementarity of the agents, and improve the comprehensive performance of killing algae and corrosion, etc. Generally, there are no special requirements for the pH of the water and the reducing substances in the water. The disadvantage is that some agents are relatively toxic , some are not easy to degrade and some are more expensive

Abstract

The invention relates to a novel killing algicide. The invention is characterized in that the novel killing algicide comprises the following components in percentage by weight: alkyl guanidinium, alkyl diethanolamide, polyvinyl alcohol, fatty amine, fatty amine additive product, quaternary ammonium salt composite, limonene, geranialdehyde, emulsifier, alkali+silicone resin auxiliary and balance of deionized water. The killing algicide provided by the invention is a non-oxidized killing algicide and can block transmission of nutrient substance in membrane, thus the aim of killing cells is achieved. When concentration of the algicide is more than 100 thousands times of application concentration, the algicide is tested to be practically non-toxic, thus the algicide is safe when being applied in a factory; the algicide can be naturally degraded into water and carbon dioxide in ecological environment; the algicide is environmentally friendly, is convenient to use, does not burn or explode and is safe and reliable; and the algicide has wide application, low price and good economy.

Description

technical field [0001] The invention relates to a novel biocide and algicide. Background technique [0002] Industrial cooling water mainly comes from rivers, rivers, lakes, and seas. These water bodies contain bacteria, algae, aquatic shellfish and their larvae to varying degrees. Once these organisms enter the industrial once-through cooling water system or industrial circulating cooling water system, At a suitable temperature for the system, bacteria and algae and shellfish grow and reproduce rapidly, and at the same time produce a large amount of biological slime, which is deposited on the surface of the pipes and equipment in the water system, reducing the diameter of the pipe and increasing the system. Resistance and end difference increase energy consumption, corrode equipment and even seriously affect normal production. Therefore, in order to save energy and increase production, enterprises must add efficient and cheap biocide and algaecide to the cooling water syst...
