Coating antiseptic how to identify good or bad?
Coating antiseptic how to identify good or bad? The key role of bactericidal preservatives used in coatings is to ensure that the coating is not damaged by bacteria and other algae. It is also the key to ensure the quality of the coating during the shelf life.
The bacteriostatic principle of many antibacterial coating preservatives is contact sterilization, which makes antibacterial coating preservatives contact with bacteria, hydrolyze the protein of bacteria, and then reduce the somatic cell specificity of bacteria, so as to kill bacteria.
Therefore, to ensure the reasonable sterilization of antibacterial coating preservatives, it is necessary to ensure that the addition of preservatives is higher than the minimum antibacterial concentration of bactericidal capacity, and to ensure that the antibacterial coating preservatives are dispersed evenly, so that the bacteria hidden in various positions in the coating can be reasonably killed.
The amount of preservatives added to antibacterial coatings should not be less than 0.1%. If the natural environment is extremely extreme and the working temperature is in an extremely hot state for a long time, the amount of addition should be moderately increased according to the situation.
In order to avoid microbial contamination resulting in product deterioration. It is necessary to treat the wall paint with corrosion protection as soon as possible. Adding preservatives to coatings is an economical and practical method.
Its polarity and non-polarity are easily dispersed, and the processing technology is not complicated. Add immediately to paints, natural latex oils and paints and stir well.
In fact, there are many kinds of paint preservatives at home and abroad. Early organic tin, organic mercury, formic acid and so on. But this raw material has been found to have a great toxic side effect on humans and small animals. In addition, the emission in the air forms air pollution. At present, the application of environmental protection, micro-toxic or non-toxic antibacterial coating preservatives is still more.
