Biological preservatives refer to a class of high-efficiency preservatives obtained from organisms through biological culture, extraction and separation technology, which has the effect of inhibiting and killing microorganisms. Food is rich in nutrition and easily corrupted by microbial contamination.

The reproduction speed is fast; Everywhere; Strong ability to adapt to the environment, easy to mutate. The coating is rich in moisture and various nutrients, providing ideal conditions for the growth of microorganisms. Excessive growth and reproduction of microorganisms can lead to paint discoloration,

Aerobic bacteria live in a mineral environment, such as water, cutting fluid concentrate and machine tool leakage of oil, in allergy and other problems, the following combined with our work in the actual experience, talk about the use of cutting fluid problems and countermeasures.

The lubrication performance of oil-based cutting fluid is good, but the cooling effect is poor.

Bacteria (The spoilage water-based metal cutting fluid taken from the site, the total number of bacterial colonies after constant temperature culture >10 mL, true

The filter paper was cut into 1cm diameter round paper, soaked and drained in the tested bactericide, and then the paper was stuck in the center of the AGAR plate with inoculated bacteria, and cultured at 36℃ for 48h. If the fungicide has a bacteriostatic effect, there is no colony growth around the paper, so as to form a round transparent bacteriostatic circle

Dow Chemical metal working fluid fungicide

The filter paper was cut into 1cm diameter round paper, soaked and drained in the tested bactericide, and then the paper was stuck in the center of the AGAR plate with inoculated bacteria, and cultured at 36℃ for 48h. If the fungicide has a bacteriostatic effect

In general, liquid fertilizers need to be added in the production and storage process to prevent the growth of bacteria, mold and other microorganisms, thereby extending the validity of the fertilizer and ensuring fertilizer efficiency. In particular,

There are many kinds of sterilization preservatives, which can be divided into inorganic sterilization preservatives and organic sterilization preservatives according to the different molecular structures.
