Coating and antiseptic fungicide will also deteriorate in the tank
Why do coatings with antiseptic and fungicide deteriorate in the tank? Most of the antiseptic fungicides used in the coating industry are non-ionic, and this kind of antiseptic fungicides are mainly consumable. Non-ionic antiseptic fungicide is like a soldier fighting, the bacteria are constantly propagating at a high speed, the antiseptic fungicide is slowly consumed in the process of eliminating bacterial spores and bacteria, and the concentration of antiseptic fungicide gradually decreases with the time. The propagation of bacteria makes the coating from neutral or alkaline into acidic environment, more promote the propagation of bacteria, at the same time, the propagation of bacteria resistance is also enhanced generation by generation, the coating added antiseptic fungicide slowly not antiseptic effect.
So, how do cationic antiseptic fungicides kill bacteria? First of all, we should understand the pH value of the coating, generally 8.5-9, the pH value of most bacterial isoelectric points is 3-4, and the property of the surface charge of bacterial cells in water is controlled by the pH value, that is, when the pH value of water is lower than the bacterial isoelectric point, the surface of bacterial cells is positively charged, otherwise negatively charged. So general water and finished paint close to neutral or alkalinity, so bacterial cell surface with negative charge. The bactericidal mechanism of cationic antiseptic fungicide is mainly that the groups contained in it are positively charged in aqueous solution, which can be adsorbed on the surface of the microorganism, form a small group, and gradually infiltrate into the lipid layer and protein layer of the microbial cytoplasm, thus changing the permeability of the cell membrane, making the cell content extravasate, leading to the death of microorganisms; At the same time, it can coagulate proteins and denature enzymes and structural proteins, thus disrupting the metabolic system of microorganisms and causing their death. After this round of sterilization, the cation is not consumed, but can continue to play a long-term bactericidal role.
A single type of antiseptic fungicide targets different bacterial groups and lineages, how can it solve the problem of long-term bactericidal and broad-spectrum antibacterial? Our compound antiseptic fungicide can achieve the elimination and inhibition of different flora and covering more lineages, and achieve long-term effect.
