preparation example Construction

[0024] The preparation method of the mixed emulsion is as follows: in parts by weight, put 2 parts peptone, 1.0 part beef extract, 1.0 part sodium chloride, 4 parts agar and 46 parts distilled water into a beaker, and place the beaker in a water bath with a temperature of 36°C. In the water bath, use a stirring device to mix and stir for 30 minutes at a rotational speed of 300 r / min, and add dropwise sodium hydroxide solution with a mass fraction of 6% to adjust the pH to 7.0 to prepare a mixed emulsion.

[0025] The preparation method of the bacteria-containing suspension is as follows: In parts by weight, 100 parts of the above mixed emulsion, 1.0 part of potassium hydrogen phosphate, 0.6 part of magnesium sulfate and 2 parts of calcium chloride are put into a beaker and mixed uniformly to prepare a preformed medium. Put the prefabricated medium and the Sphingosine multiphagous bacteria powder into a glass dish at a mass ratio of 100:1, place the glass dish in an incubator, and ...

Abstract

The invention relates to a preparation method of oil removal powder, and belongs to the technical field of oil stain cleaning product preparation. The preparation method comprises the following stepsof firstly preparing a prefabricated culture medium by taking peptone, beef extract, potassium hydrogen phosphate, magnesium sulfate and the like as raw materials; then dissolving the chitosan into anacetic acid solution to prepare a dispersion liquid; then uniformly mixing span 80, tween 60 and petroleum ether to prepare a mixed solution; and finally mixing and drying the reaction product, sodium carbonate and the like to prepare the oil removal powder. According to the method, substances such as peptone, beef extract and the like are used as raw materials, the oil removal effect of the oilremoval powder is improved by utilizing the degradation capability of the strain to petroleum, so that the contact probability of oil removal powder and oil is increased, the oil removal capability isimproved, the chitosan is dissolved in an acetic acid solution, surface activity modification is carried out by using span 80 and tween 60, amino, hydroxyl and other functional groups are easier to bond and adsorb, the structural strength of the chitosan microsphere is improved, and then the chitosan microsphere is subjected to freeze treatment, so that the contact degree of the strain and the oil is improved, the oil removal performance is improved, and the application prospect is wide.

Description

Technical field [0001] The invention relates to a preparation method of degreasing powder and belongs to the technical field of preparation of oil stain cleaning products. Background technique [0002] Cleaning the workpiece is one of the important processes in the industry, mainly for the cleaning of some heavy oily workpieces in the industry. The degreasing effect will directly affect the quality of the coating and coating. Traditional degreasing methods include: high-temperature chemical degreasing, organic solvent degreasing, electrochemical degreasing, high-temperature lye degreasing, etc., which are gradually removed by alkaline due to high cost, high energy consumption, heavy pollution, and poor operating environment. Replace with oil powder. [0003] Degreasing powder is a low-foaming degreasing degreaser refined with a variety of high-quality surfactants, detergents, penetrants, builders, etc. It mainly utilizes the saponification reaction of ester substances in oil and ...
