Application of efficacy antiseptic anti-mold agent in coatings

China Paint Online News Information
The smaller the MIC value of anti-corrosion and anti-mold agent, the higher the anti-mold and anti-mold performance of this anti-mold agent, the better the application effect, MIC value has become anti-corrosion, anti-mold agent development, production, application personnel on anti-corrosion, anti-mold agent product effect understanding of a basic data.The anti-bacterial ring experiment is a test method that uses anti-corrosion, anti-mold agent to dissolve continuously and form different gradients by agar diffusion, according to the different anti-corrosion, anti-mold agent on the surface of a specific medium to determine the size of the anti-bacterial ring of the species to judge the anti-corrosion, anti-mold agent anti-mold inhibitor ability. The advantage of this method is that it is simple to operate and intuitive.Minimum inhibition concentration (MIC) experiment is based on the test bacteria in various concentrations of anti-corrosion, anti-mold agent on the culture base plate can grow and develop, to determine the anti-corrosion, anti-mold agent on the microorganism's minimum inhibition concentration, the method is applicable to insoluble and soluble anti-corrosion, anti-mold detection, can better reflect the size of anti-corrosion, anti-mold agent, is currently one of the most common anti-corrosion expression of anti-corrosion, anti-mold agent.the first two methods of artificial environment long mold test method are directly for anti-corrosion, anti-mold test method, not applicable to the test of the anti-mold effectiveness of water-based coatings as anti-mold products. Artificial environmental long mold test is the most important and widely used method to determine the anti-mold effectiveness of water-based coatings. This method simulates the environmental conditions of mold growth in nature and designs the test according to the physiological characteristics of mold growth, which is used to determine the inhibition of mold by paint film under conditions suitable for mold growth. The bactericidal spectrum and environmental biology limitations of these products have been gradually understood, has been gradually abandoned, replaced by a safer, less toxic, simple operation of modern anti-mold fungicides. To choose the right anti-corrosion, anti-mold agent, first of all, it is required to meet the characteristics of the coating to meet its related requirements.water-based coatings 1 are mainly used in brewing, food, beverage, medicine, chemicals, buildings, underground buildings and other special circumstances. The main characteristics of these environments are high humidity, high temperature, rich in nutrients, very suitable for mold growth. Therefore, it is more critical to solve the problem of anti-mold coating of water-based coatings. In accordance with the basic principles and requirements of the above-mentioned selection of ideal paint film anti-mold agent, we have developed an environmentally friendly paint film anti-mold agent mainly suitable for water-based coatings KM-01 paint film anti-mold remover. In the process of development, microbial testing means are used effectively to form a stable, water-dispersed system of the original hydrophobic active ingredients through special additives and appropriate process cooperation. In addition, according to the use of water-based coatings should be selected in the tank preservatives and paint film mold inhibitors and design its appropriate dosage. First of all, to consider the use of regional climatic conditions, in hot and humid areas, all kinds of microorganisms breed rapidly, should use high-efficiency fungicides and high dosage; Secondly, the exterior paint not only by the impact of the sun, but also by the erosion of wind and rain, but also need to give special consideration.Because of the different types of preservatives and mold inhibitors have different mechanisms of action, have their own different antibacterial spectrum, in some cases, a variety of preservatives and mold inhibitors compound use, can play a complementary and synergistic role, more effective than the use of a single preservative or mold inhibitor, in expanding the broad spectrum of antibacterial, can reduce the concentration of use, thereby improving product safety. Obviously, compound anti-corrosion anti-mold agent in the future paint anti-corrosion anti-mold system will dominate, in the green anti-corrosion, anti-mold has become the majority of consumers favorite today, compound, efficacy anti-corrosion anti-mold agent development, development and application will have great prospects for development.
