Common knowledge of coating: application of epoxy resin self leveling floor in modern clean workshop

Core tip: with the development of modern industrial technology and production, the requirement of cleaner production is higher and higher, which requires the car floor to be corrosion-resistant, clean and wear-resistant, and the indoor air dust content is as low as possible Among them, the production of clean floor is an important guarantee for the production environment of modern clean workshop It has been proved that the self leveling floor of epoxy resin can meet the requirements of modern clean workshop Epoxy resin self flowing flat surface is made of epoxy resin as polymer surface layer, adding various curing agents, pigments, fillers and other auxiliary materials according to different requirements, processing into film according to a certain proportion, and taking the concrete floor as the bottom Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings news: with the development of modern industrial technology and production, the requirements for cleaner production are higher and higher It is required that the car floor should be corrosion-resistant, clean and wear-resistant, and the indoor air dust content should be as low as possible Among them, the production of clean floor is an important guarantee for the production environment of modern clean workshop It has been proved that the self leveling floor of epoxy resin can meet the requirements of modern clean workshop Epoxy resin self flowing flat is made of epoxy resin as polymer surface layer, various curing agents, pigments, fillers and other auxiliary materials according to different requirements, processed into film according to a certain proportion, and made of concrete floor as bottom layer Compared with the traditional ordinary mortar and anti-corrosion floor, the self leveling floor of epoxy resin has the advantages of cleanness, high strength, resistance to a small amount of impact, acid and alkali resistance, etc.; compared with other types of epoxy resin floor, it has the characteristics of seamless and smooth, beautiful and easy to clean, dustproof and bacteria proof, etc.; it is especially suitable for the high-tech electronics, medicine and other workshops that need high cleanness but do not need large abrasion and impact resistance 1 Construction process of self leveling floor with epoxy resin 1.1 inspection and treatment of base course concrete base course shall meet the requirements of smooth surface without hollowing and sanding 1.1.1 inspection of base concrete inspection of base concrete includes the measurement of concrete moisture content, flatness, pH value and strength 1) Determination of moisture content The test method for moisture content of base concrete can be plastic film method: place the 45cm × 45cm plastic film on the concrete surface, seal the four sides with adhesive tape for 16h, and water drops appear under the film or the concrete surface turns black, indicating that the concrete is too wet to be painted 2) Flatness measurement A board with a flat surface shall be placed on the concrete surface with a corner of the floor as the starting point, and then the deviation between the base and the Board shall be measured with a level bar, and the maximum deviation shall not exceed 2mm 3) PH measurement Before pouring concrete, take some raw materials of concrete as samples, and use pH test paper to measure the pH value of concrete If the pH value is less than 10, it is qualified 4) Strength determination If the strength of the test block reaches 21.0spa, it is qualified 1.1.2 the moisture content of concrete shall be less than 9%, otherwise, the coating can be carried out after the moisture content is removed The ventilation method should be used to remove the moisture in the base concrete (usually there are many combustibles in the plant, so it is not easy to ensure the safety of indoor heating) 1.1.3 base course surface treatment method acid washing method: wash the concrete surface with 10% - 15% hydrochloric acid, after the reaction is complete (no bubble is generated), wash with clean water, and brush with a brush This method can remove the mud layer and get a smaller roughness 1.2 one or two coats of primer shall be applied by brush or roll coating, with an interval of more than 8h; another coat of primer shall be added on the old base course 1.3 solventless sealed solventless epoxy coating plus a proper color paste coating, and it is required to be smooth, bright and seamless 1.4 for the pit on the cement surface, the same type of concrete shall be used for filling and repairing, and the pit shall be polished and leveled after natural curing and drying 1.5 scrape the surface layer with scraper to gently scrape the cured mixture film to make it evenly distributed 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,
