Embodiment 1

[0073] Embodiment 1: first get the activated Streptomyces 1 and inoculate it into an appropriate amount of Streptomyces 1 liquid medium, expand and cultivate it for 1 day at 30°C, and obtain the seed culture solution through two times of expansion cultivation; the seed culture solution is inoculated with an appropriate amount of Inoculate a large amount of bacteria into the enrichment medium, shake and culture at 30°C for 1 day to obtain the bacterial liquid; then centrifuge the collected bacterial liquid, discard the supernatant, wash the precipitated bacterial cells with 0.9% sterile normal saline, and then Centrifuge, discard the supernatant, and the obtained precipitate is the Streptomyces 1 cell; then fully dry the Streptomyces 1 cell at about 30°C to obtain the powder Streptomyces 1 cell; After the protective agent 1 is fully mixed, it is filtered to obtain a spore suspension, which is a biologically stable preparation. Wherein, the pH of Streptomyces 1 liquid culture me...

Embodiment 2

[0074] Embodiment 2: first get the activated Streptomyces 2 and inoculate it into an appropriate amount of Streptomyces 2 liquid culture medium, expand and cultivate it at 30°C for 2 days, and obtain the seed culture solution through two expansion cultures; the seed culture solution is inoculated with an appropriate amount of Inoculate a large amount of bacteria in the enrichment medium, shake and culture at 30°C for 2 days to obtain the bacterial liquid; then centrifuge the collected bacterial liquid, discard the supernatant, wash the precipitated bacterial cells with 0.9% sterile normal saline, and then Centrifuge, discard the supernatant, and the obtained precipitate is the Streptomyces 2 cells; then fully dry the Streptomyces 2 cells at about 30°C to obtain the powder Streptomyces 2 cells; finally mix the powder and the cells After the protective agent 1 is fully mixed, it is filtered to obtain a spore suspension, which is a biologically stable preparation. Wherein, the pH...

Abstract

The invention provides a biostable metalworking fluid without a fungicide and a preparation method thereof, wherein the biostable metalworking fluid without a fungicide comprises the following components in parts by weight: 20-60 parts of base oil , 3-30 parts of emulsifier, 5-30 parts of alkali value reserve agent, 1-10 parts of biological stabilizer, 0-20 parts of other additives, 3-15 parts of water. The biostable metalworking fluid without bactericide of the present invention has good biostability, is environmentally friendly, has no adverse effect on operators, and has excellent lubricating performance.

Description

technical field [0001] The invention belongs to the technical field of metal working fluids, and in particular relates to a biologically stable metal working fluid without bactericide and a preparation method of the biological stabilizer. Background technique [0002] Metalworking fluid corruption is mainly caused by the proliferation of microorganisms in the system. This is because the base oil and certain additives in the processing fluid are nutrients for the survival of microorganisms. When the bacteria multiply, it will cause the pH value of the processing fluid to drop, and produce an unpleasant smell; when the fungus multiply, there will be lumps in the processing fluid, and these lumps will easily block the circulation pipeline and filter screen of the machine tool. The decomposition of these microorganisms to the processing fluid will cause the reduction of the lubricity, rust resistance, and stability of the processing fluid, cause wear and corrosion to machines, ...
