Dibromonitrilopropionamide (alias dibromocyanoacetamide, DBNPA for short) is a new and efficient bactericidal algaecide and water treatment agent. The material has the advantages of high-efficiency broad spectrum, easy degradation, no residual residue, no pollution to the environment, and at the same time,

Dow Chemical metal working fluid fungicide

The pH value of the test solution was determined every day, the appearance changes and odor emission were observed, and the number of bacteria and fungi were determined after 5 days of ventilation and 2 days of deaeration. Repeat until the water-based metal cutting fluid deteriorates. Due to the microbial reproduction process, cellular respiration releases CO2 and the organic acids produced in the degradation process will cause the pH value to drop. Therefore, the biological stability of water-based metal cutting fluid can be evaluated by the degree of pH reduction and the degree of microbial reproduction

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.
