Coating process: mould proof test of coating

The key points are as follows: A in the wet greenhouse test, the test sample was placed in the glass kitchen for mold suspension spraying, and dried after infection with mold Then move the sample to constant temperature and humidity chamber or test chamber for hanging, keep the temperature (28 ± 1) Tun and relative humidity (98 ± 1)% in the chamber, observe the mould growth on the sample and evaluate the grade (the rating standard can be in accordance with the provisions of gbl74l test method for mould resistance of paint film) The general test period is 28d b Test of r0be by suspension method in mould chamber 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 Paint Home News: A wet greenhouse test put the test sample in the glass kitchen for mold suspension spraying, and dry after infection with mold 10 Then move the sample to constant temperature and humidity chamber or test chamber for hanging, keep the temperature (28 ± 1) Tun and relative humidity (98 ± 1)% in the chamber, observe the mould growth on the sample and evaluate the grade (the rating standard can be in accordance with the provisions of gbl74l test method for mould resistance of paint film) The general test period is 28d b R0bert asmiih designed the hanging method of mould chamber The 3 / 4 surface area of the sample was coated with coating sample, and the 1 / 4 surface area (generally the upper part of the sample) was not coated with the sample The sample was connected with the strain and placed in the room with the temperature of 28-30 ℃ and the relative humidity of 95% The mould growth of the sample was observed regularly and the rating was evaluated (the rating standard is the same as above) The test takes 28 days c The purpose of this test is to evaluate the durability of coatings Before the mold resistance test, the test sample of the coating to be tested shall be subject to the aging treatment simulating the natural environment and climate, and the artificial aging time shall be determined according to the requirements Then, the experiment was carried out according to the wet greenhouse method or mould chamber suspension method d In the field exposure test, the samples coated with the tested anti mold coating are placed in the actual environment, such as the jungle, hot and humid areas, etc for inspection, or in the cigarette factory, brewery, food processing factory and other places where the anti mold coating is required for field coating test, and the surface conditions are regularly observed Obviously, the most accurate results can be obtained by field test The technical requirements of antifungal coating products should also include the toxicity requirements, because the antifungal coating with high toxicity still has no practical value Toxicity test should include acute oral toxicity test, skin irritation test, eye irritation test and mutagenicity test 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,
