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

Abstract
The invention discloses a non-phosphorus oil-removing type powder cleaning agent with magnetic graphene oxide and immobilized degrading bacteria. The non-phosphorus oil-removing type powder cleaning agent is prepared from the following raw materials of sodium hydroxide, sodium carbonate, sodium metasilicate pentahydrate, a silicic acid and organic carboxylic acid modified polymer, sodium dodecyl benzene sulfonate, carbonyl alcohol ethoxylate, sodium gluconate, dodecyl phosphate ester, polyoxyethylene ether, disodium ethylate ethanedioic acid, graphene oxide, nanometer titanium dioxide, carbon dimethylamine hydrochloride, N-hydroxysuccinimide, nanometer iron oxide, moderate absolute ethyl alcohol, moderate sodium hydroxide, moderate 0.9% sodium chloride and moderate deionized water. The powder cleaning agent has the advantages of non phosphorus, wide raw material source, low preparation cost, no toxin and no harm to the environment, good cleaning effect for various sectional materials, low energy consumption and man hour saving and improves the efficiency, the generated waste water is easier to dispose, and therefore the powder cleaning agent is worth of being generalized.
Description
technical field [0001] The invention relates to the technical field of metal surface treatment agents, in particular to a non-phosphorous degreasing powder cleaning agent and a cleaning process for fixing and degrading bacteria of magnetic graphene oxide. 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. ...
