What are the main applications of fungicide?
Bactericidal preservatives are mainly used to ensure that materials do not deteriorate during use by killing bacteria or making them lose their ability to grow and reproduce. Bactericidal preservatives can denature proteins in microorganisms, reduce the activity of cells, promote the death of bacteria, and can also mutate the cellular genetic genes of microorganisms or interfere with the activity of enzymes inside cells to make it difficult to reproduce.
According to reports, the microorganisms that can erode the paint are mainly bacteria, mold, yeast and algae. The main microorganisms that cause coating spoilage are Gram-negative bacteria, especially coliform and Pseudomonas, rather than mold as usually thought, and the main microorganisms that breed on the coating film after coating are mold and algae.
Therefore, to prevent the deterioration of the paint, the most important thing is to control gram-negative bacteria, especially colibacterium and pseudomonas, that is, the bactericidal preservatives added should have the best effect on Gram-negative bacteria. If the coating film after painting is not required to grow mold, you can add preservatives at the same time and then add dry film anti-mildew agent, the two are used together, you can achieve the 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.
