What are the uses of mildew prevention agents used in different places
What are the uses of mildew prevention agents used in different places? Each kind of products need to use mildew prevention agent, so different products for the use of mildew prevention agent are what use?
The smaller the MIC value of anticorrosion and mildew prevention agent is, the higher the mildew and antibacterial performance of the anticorrosion and mildew prevention agent is, and the better the application effect is. The MIC value has become one of the most basic data for the development, production and application personnel of anticorrosion and mildew prevention agent to understand the effect of anticorrosion and mildew prevention agent.
Bacteriostatic zone method Bacteriostatic zone experiment is a test method to determine the ability of antiseptic and mildew inhibiting agents according to the size of bacteriostatic zone displayed by different antiseptic and mildew inhibiting agents on the surface of specific culture medium by using the continuous dissolution of antiseptic and mildew inhibiting agents and forming different gradients through AGAR diffusion. The advantages of this method are simple operation and good intuitiveness.
The minimum inhibitory concentration (MIC) test is based on whether the test strains can grow and develop on the medium plate of various concentrations of antiseptic and antifungal agents to determine the minimum inhibitory concentration of the antiseptic and antifungal agents on this microorganism. This method is suitable for the detection of insoluble and soluble antiseptic and antifungal agents, and can better reflect the effectiveness of antiseptic and antifungal agents. At present, it is one of the most common expression ways of anti-killing properties of antiseptic and anti-mold agents.
Mildew test methods in artificial environment The first two methods are directly aimed at anti-corrosion and anti-mildew agents, and are not suitable for the test of the anti-mildew efficacy of waterborne coatings as anti-mildew products. Mildew growth test in artificial environment is the most important and widely used method to determine the mildew control effectiveness of waterborne coatings. This method is designed to simulate the environmental conditions of natural mold growth and according to the physiological characteristics of mold growth. It is used to determine the inhibitory effect of paint film on mold growth under suitable conditions. As the bactericidal spectrum and environmental biological limitations of these products have gradually been understood, they have been gradually abandoned in favor of safer, less toxic and easier to operate modern antifungal fungicides. To choose the appropriate anti-corrosion, anti-mildew agent, first of all, it can meet the characteristics of the coating related requirements.
Because waterborne coatings 1 is mainly used in wine, food, beverage, medicine, chemical industry, building buildings, underground buildings and other special environment. The main characteristics of these environments are high humidity, high temperature, rich nutrients, very suitable for mold growth. Therefore, it is more critical to solve the mildew proof problem of waterborne coatings. According to the above-mentioned basic principles and requirements for the selection of ideal paint film anti-mildew agent, we developed a kind of environmental protection type paint film anti-mildew bactericide KM-01 paint film anti-mildew bactericide mainly suitable for water-based paint. In the process of development, the effective use of microbial testing means, through special auxiliaries and appropriate technology coordination, the original hydrophobic active ingredients formed a stable, dispersed in water system. In addition, should also be based on the use of water-based paint environment to choose the tank preservatives and paint film anti-mildew agent and design its appropriate dosage. First of all, to consider the use of regional climate conditions, in hot and humid areas, all kinds of microorganisms breed rapidly, should use highly effective fungicide and the dosage is higher; Secondly, the exterior wall coating should not only be affected by the sun, but also by the erosion of wind and rain, also need to give special consideration.
Due to the different mechanism of action of different kinds of preservatives and mildew inhibitors, they have different antibacterial spectra. In some cases, the combination of a variety of preservatives and mildew inhibitors can play a complementary and synergistic effect, which is more effective than the use of a single preservative or mildew inhibitor. While expanding the antibacterial broad spectrum, the concentration can be reduced, thus improving the safety of products. Obviously, compound anticorrosive and mildew proof agents in the future coating anticorrosive and mildew proof system will play a dominant role, in the green anticorrosive and mildew proof become the majority of consumers favor today, the research, development and application of compound, efficacy anticorrosive and mildew proof agents will have great prospects for development.
