Main applications of antiseptic?
Bactericidal preservatives are mainly used to kill bacteria or make them lose the ability to grow and reproduce to ensure that materials in the process of use do not produce spoilage. Bactericidal preservatives can denature proteins in microorganisms, reduce cell activity and promote bacterial death. They can also mutate cellular genetic genes of microorganisms or interfere with enzyme activity inside cells, making it difficult for them to reproduce.
According to the report, the main microorganisms capable of eroding paint are bacteria, mold, yeast and algae. The main microorganisms that cause coating spoilage are Gram-negative bacteria, especially E. coli and Pseudomonas, rather than mold as commonly believed. The main microorganisms that grow on the coating film after coating are mold and algae.
Therefore, to prevent the deterioration of paint, the most important thing is to control gram-negative bacteria, especially the large intestine oxygen-producing bacteria and pseudomonas, that is, the addition of bactericidal preservatives to deal with gram-negative bacteria have the best effect. If the coating film after coating is not mildew, preservatives can be added at the same time and then add dry film mildew prevention agent, the two use together, you can achieve antibacterial effect from beginning to end. If it is a boat primer, it is also necessary to add algaecide to prevent the growth of algae.
