    Core tip: anti mold coating is a functional coating whose coating can inhibit the growth and propagation of mold

    It is mainly used for the wet places with poor ventilation and the wall finishing of factory buildings rich in nutrients in the environment, which plays a role of beautification and protection

    The occurrence of mould not only makes the eroded coating surface very unsightly, but also the mould growing in the deep layer will break through the paint film and cause cracking and peeling

    The mould gives off a peculiar odor

    People living in this environment are not happy physically and mentally, and their health is threatened; The products produced in this environment are easy to be polluted and damaged, which is not in line with civilized production

    So, for a long time, people Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively

    The feature of the breathing wall is obvious

    When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity

    It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively

    The feature of the wall that can breathe is obvious

    When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: anti mildew coating is a functional coating whose coating can inhibit the propagation and growth of mold

    It is mainly used for the wet places with poor ventilation and the wall coating of factory buildings rich in nutrients in the environment, which plays a role of beautification and protection

    The occurrence of mould not only makes the eroded coating surface very unsightly, but also the mould growing in the deep layer will break through the paint film and cause cracking and peeling

    The mould gives off a peculiar odor

    People living in this environment are not happy physically and mentally, and their health is threatened; The products produced in this environment are easy to be polluted and damaged, which is not in line with civilized production

    Therefore, people have been trying to fight against mould for a long time

    Once upon a time, people used lime water to paint walls and got two major fruits of sterilization and decoration, which is the prototype of modern anti mildew coating

    With the development of science, especially the rapid development of the production and technology of anti mildew and bactericide, today's anti mildew coating is applied on the interior walls of workshops such as cigarette factories, breweries and pharmaceutical factories, where the environment is very bad

    The life of the coating is more than 2 years, and the coating is beautiful, decorative and toxic

    All over the world, especially in the United States, Japan and Europe, the research on mildew resistant coatings and fungicides is very active

    Hundreds of patents and literatures are published every year

    In recent ten years, the development of mildew resistant coatings in China is very fast

    So far, dozens of factories around the country have developed various grades of mildew resistant coatings

    Fungicide is a kind of chemical with the ability to inhibit and kill microorganisms such as mould and algae

    After the action of fungicide, many characteristics of microorganisms will change, such as generation, propagation, spore formation and germination, and cell silk Division and permeability, respiration and other physiological and biochemical reactions and metabolic activities will be affected

    Therefore, the cell membrane, cytoplasm and nucleus of microorganisms can become places of sterilization or bacteriostasis

    As the bacterial cell is a kind of semi permeable membrane, a chemical should have bactericidal power

    It should not only have the chemical toxic group, but also have the permeability to the bacterial cell

    The semipermeable membrane of bacterial cell is composed of fat layer and protein

    The inner and outer layers are protein, and the fat layer is sandwiched between them

    Therefore, if the bactericide wants to penetrate human cell, it must have hydrophilicity and lipophilicity

    In addition, the fat layer of the semipermeable membrane is connected with the protein through the polar group, that is, the semipermeable membrane is charged, which will hinder the penetration of ionic bactericides, thus reducing the toxicity of such chemicals

    The action mechanism of bactericide is to destroy the cell structure of bacteria, prevent the mitosis of bacteria, affect the metabolism of bacteria, form metal chelate (so that metal can not participate in the normal reaction of bacteria cells), and hinder the synthesis of ester like bacteria

    In fact, it is very difficult to find an ideal bactericide that fully meets the conditions

    Sometimes, two or more fungicides with different characteristics are used to improve the efficacy and broad-spectrum of sterilization, and some additives can be added to improve the compatibility and stability

    In the case that various conditions cannot be completed, the first consideration of the designer is often the mildew prevention effect, that is, the ability of bactericide to inhibit or kill mold, bacteria, yeast and other necessary microorganisms, which is generally shown by the filter paper bacteriostatic circle or the minimum concentration of drug to inhibit microbial development
