Magnetism 4A zeolite fixed degrading bacteria heavy-dirty composite powder metal cleaning agent and cleaning process

Abstract

The invention discloses a magnetism 4A zeolite fixed degrading bacteria heavy-dirty composite powder metal cleaning agent. The cleaning agent is prepared by the following raw materials: sodium hydroxide, sodium carbonate, sodium metasilicate pentahydrate, silicic acid-organic carboxylic acid polymerization modified matters, crylic acid-maleic anhydride copolymer sodium salt, lauryl sodium sulfate, heterogeneous fatty alcohol alkoxylate, secondary alcohol ethoxylate, anhydrous sodium sulphate, sodium citrate, kaolin, magnetic fluids, a proper amount of sodium hydroxide, a proper amount of 0.9% sodium chloride, and a proper amount of de-ionized water. The prepared powder cleaning agent contains no phosphorus, cannot cause pollution of water, is environment-friendly, high in cleaning effect, wide in application range and longer in service life, and is more liable to treat generated waste water.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment agents, in particular to a magnetic 4A zeolite-fixed degrading bacteria heavy scale compound powder metal cleaning agent and a cleaning process. Background technique [0002] Before the metal is processed, the anti-rust oil, cutting fluid and other dirt on the surface must be cleaned. The traditional metal surface cleaning solution is mainly prepared with alkali, phosphate builder, nonylphenol or octylphenol surfactant. The working temperature during cleaning is generally higher than 80°C. This process consumes a lot of energy. The phenolic surfactants used are biologically toxic and difficult to degrade. They remain in water for a long time. If the phosphate in the waste liquid is not If it is thoroughly treated, the phosphorus element in it will be carried out in a large amount into the natural water body, which will cause the eutrophication of the water body.

Problems solved by technology

Although the method provided in this article has the advantages of environmental protection, low cost and fast cleaning rate, etc., the degreasing powder has a relatively high concentration of alkali, which is not suitable for the pretreatment of alloys, which limits the application field, and during use It is inevitable to produce a large amount of oily waste liquid. Although it can clean the oil stain on the steel surface, it cannot decompose the oil stain. Therefore, in order to solve the above problems, it needs to be further modified to have the functions of degreasing and decomposing oil stains at the same time, and to expand the scope of use. , in order to meet the cleaning of various profiles
