Coating classification: mould proof coating

Core tip: generally, the most suitable environment for mold growth is the temperature of 23-38 ℃, relative humidity of 85% - 100% Therefore, the internal and external walls of buildings in the temperature and humidity areas, and the walls, ceilings, ground, underground works in the constant temperature and humidity workshops in other areas are suitable for mold growth If the ordinary decorative coating is used, it will also be eroded by mould in different degrees Mould will erode the coating of organic coating more seriously The coating will fade, stain and even fall off after being corroded by mould This is because when mould erodes the paint film, it secretes enzymes These secretes Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of paint news: generally, the most suitable breeding and growth of mold is in the natural conditions of 23-38 ℃, relative humidity of 85% - 100% Therefore, the internal and external walls of buildings in the temperature and humidity areas, as well as the walls, ceilings, ground, underground works and other areas in the constant temperature and humidity workshop are suitable for the growth of mold If the ordinary decorative coating is used, it will also be eroded by mould in different degrees Mould will erode the coating of organic coating more seriously The coating will fade, stain and even fall off after being corroded by mould This is because after the mold erodes the paint film, it will secrete enzymes These secretions will further decompose the organic film-forming substances in the paint, and become the nutrients for the growth of the mold, thus damaging the entire coating The so-called antifungal coating is a kind of functional coating which can inhibit the growth of mold, usually by adding a certain antibacterial agent in the coating to achieve the purpose In the storage process of traditional paint or other decorative coating, in order to prevent the liquid coating from mildew caused by the action of bacteria, a certain amount of preservative is often added, but the amount of preservative in this kind of coating is far less than the amount of antibacterial agent in the anti mold coating, so only the anti-corrosion effect of the coating, but no anti mold effect of the coating This kind of coating is not included in the scope of anti mildew coating The main characteristics of building anti mildew coating are not only good anti mildew performance, but also good decorative performance In the environment where mould is easy to grow, the surface of the building is not easy to mould after being coated with anti mould coating And because the anti mildew coating is used for the interior and exterior walls, ceilings or floors of buildings, it must also have a better decorative effect According to the different film-forming materials and dispersing media, antifungal coating can be divided into solvent type and water emulsion type, and can also be divided into external use, internal use and special use antifungal coating The fundamental difference between antifungal coating and common decorative coating is that the former adds a certain amount of mold inhibitor in the coating manufacturing process There are many kinds of mould in the natural environment, such as Aspergillus niger, Aspergillus flavus, Aspergillus discoloration, Penicillium citrinum, Paecilomyces, Cladosporium cereus, etc Therefore, the inhibitors must be able to inhibit the growth of these molds The mould inhibitor used in the general anti mould building coating shall meet the following requirements: the substance will not be mixed with the components (film forming substance, pigment) in the coating , fillers and additives) have chemical reaction and lose the effect of inhibiting the growth of mould; will not dye or discolor the color in the paint; can be evenly distributed in the paint; after the paint is painted, the material can be evenly distributed in the coating, can inhibit the growth of mould on the surface of the coating for a long time; after the paint is coated, it is harmless to human body The commonly used fungicides are: pentachlorophenol sodium, phenylmercury acetate, carbendazim, chlorothalonil and various special fungicides, among which pentachlorophenol sodium and phenylmercury acetate are toxic, so you should be careful when using them Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
