Problems solved by technology

These existing degreasing agents are not environmentally friendly during use, and the oil after emulsification cannot be decomposed in time
[0003] The oil stain on the metal surface is often composed of stamping oil, cutting oil, lubricating oil, animal oil and other oils. A single strain of bacteria often cannot degrade this mixed oil quickly and comprehensively.

Embodiment 1

[0013] Firstly, screen, enrich and acclimatize Bacillus kinesis, Bacillus mohaiwei, Bacillus subtilis and Serratia marcescens respectively, at a temperature of 32°C-36°C, pH6.5-8.5, 140r / min Conditioned for 24h.

[0014] Then take 2.6mL of the cultured Bacillus kinesis, 4.3mL of Bacillus mohaiwei, 2.3mL of Bacillus subtilis, and 3.5mL of Serratia marcescens, and mix them to prepare the biological components required for 1L of biological compound degreasing agent.

Embodiment 2

[0016] Firstly, screen, enrich and acclimatize Bacillus kinesis, Bacillus mohaiwei, Bacillus subtilis and Serratia marcescens respectively, at a temperature of 32°C-36°C, pH6.5-8.5, 140r / min Conditioned for 24h.

[0017] Then take 5.5mL of the cultured Bacillus kinesis, 9mL of Bacillus mohaiwei, 4.5mL of Bacillus subtilis, and 7mL of Serratia marcescens, and mix them to prepare the biological components required for a 2L biological compound degreasing agent.

Abstract

Relating to the technical field of surface degreasing of metallic materials, the invention provides a preparation method for a biological component of a biological compound degreaser. The method comprises the steps of: conducting screening, enriching, domestication and culturing respectively to zoogloea, Bacillus mojavensis, bacillus subtilis, Serratia marcescens, then taking each cultured bacterium in proportion so as to prepare the biological component of a biological compound degreaser. The biological component prepared by the selected 4 bacteria in the invention can degrade mixed oil stains of punching oil, cutting oil, lubricating oil, animal oil and a plurality of oil, and can realize rapid and comprehensive degradation as well as excellent degrading effects.

Description

Technical field: [0001] The invention relates to the technical field of metal material surface degreasing, in particular to a method for preparing biological components of a biological compound degreasing agent. Background technique: [0002] Before metal chemical treatment, electroplating and coating, degreasing agent should be used to remove grease and mineral oil on the metal surface. The main degreasing agents are as follows: (1) Alkaline degreasing agent, composed of alkali, chelating agent and surfactant; (2) Emulsion degreasing agent, using the wettability, penetrability, emulsification and dispersibility of surfactant Can remove the dirt on the metal surface. Generally, one or several mixtures of anionic, cationic, nonionic and other surfactants are used, and diluted with water to make an emulsion; (3) solvent degreasing agent, degreasing by dipping method or steam method. The main solvents used are halogenated hydrocarbon solvents and fluorinated hydrocarbon solve...
