Coating standard: the first waterborne anticorrosive coating standard issued by Guangdong

Core tip: Recently, Guangdong Province officially approved the issuance of "two component standard for waterborne polyurethane anticorrosive coatings", which will be implemented from March 31, the first standard for waterborne anticorrosive coatings issued in China The promulgation and implementation of the new standard has promoted the construction of waterborne product standard system in the coating industry of the province, is conducive to guiding the development of waterborne anticorrosive coating industry, will drive the development of heavy anticorrosive material production enterprises towards the direction of green environmental protection, improve the level of coating process automation, enhance the independent innovation ability of enterprises, and promote the ship coating and other products to reach the level of similar products abroad as soon as possible “ Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: Recently, Guangdong Province officially approved the release of "two component standard for waterborne polyurethane anticorrosive coatings", which will be implemented from March 31, which is the first standard for waterborne anticorrosive coatings issued in China The promulgation and implementation of the new standard has promoted the construction of waterborne product standard system in the coating industry of the province, helped to guide the development of waterborne anticorrosive coating industry, and will drive the heavy anticorrosive material production enterprises to move towards green and environmental protection We should develop the direction, improve the automation level of coating process, enhance the independent innovation ability of enterprises, and promote the marine coating and other products to reach the level of similar products abroad as soon as possible Lu shuilie, Deputy Secretary General of Guangdong coating industry association, introduced the development direction of "water-based" At present, there are dozens of anticorrosive coatings, including resins, modified resins, powders, solventless, UV curing, glass scales, etc However, in China, the overall development level of the coating industry is relatively low, especially the development of heavy anti-corrosion coatings for ships is still in the initial stage Although there are nearly one thousand enterprises specializing in the production of anti-corrosion coatings, the scale is not large, and there are few high-end products, and the supply of low-end products exceeds the demand With the increasing requirements of the market for the environmental protection performance of products, many anticorrosive coatings with excellent performance have emerged in recent years, and gradually develop to the direction of green environmental protection Among them, the application technology of epoxy resin and polyurethane coating in the field of industrial anticorrosion is more mature, and widely used in the ship industry The waterborne polyurethane anticorrosive coating has been used more and more because of its non flammable, non-toxic, pollution-free, energy saving, easy storage and high hardness and wear resistance In response to this trend, Lu Shuili reminded domestic anti-corrosion coating enterprises to take the development of water-based anti-corrosion coating as an important way to "green" coating, such as vigorously developing high-performance anti rust coating, super weather resistant coating, ship heavy-duty anti-corrosion coating with more than 15 years anti-corrosion effect, high-temperature resistant coating with special functions and heat insulation Coating, antistatic coating, low energy consumption aliphatic polyurethane coating and epoxy resin coating, etc At the same time, due to the complex construction environment of heavy-duty anti-corrosion coating, relevant enterprises should pay attention to the environmental adaptability of products when conducting research and development, and strive to make them not limited by the structure and shape of equipment, and have the characteristics of convenient repair and cooperation with other anti-corrosion measures It is urgent to be guided by the "standard" before the "two component standard for waterborne polyurethane anticorrosive coatings" was issued in Guangdong Province, but no relevant standards for waterborne anticorrosive coatings have been issued in China In accordance with the provisions of the measures for the administration of industrial product standards, all standards for industrial products without specific standards shall refer to and implement the relevant standards of the integrated product system However, because the solvent based product standard system of anti-corrosion coating fails to reflect some main indicators of water-borne anti-corrosion coating products and cannot ensure the quality of water-borne anti-corrosion coating products, there is not a set of applicable quality indicators in this field, resulting in the uneven quality of products produced by various manufacturers, which also hinders the development of this industry Therefore, it is imperative to perfect the construction of the standard system of waterborne products in the paint industry and to formulate a set of standards for waterborne anticorrosive coating products The two-component standard for waterborne polyurethane anticorrosive coatings issued by Guangdong Province specifies the classification, test methods, inspection rules, marks, packaging and storage of the two-component waterborne polyurethane anticorrosive coatings in detail, which has strong guidance and practicability It establishes a clear product index system for the production and application of waterborne anticorrosive coatings, and enables the engineering design in the field of anticorrosion Have technical index basis and reference The implementation of this standard is conducive to promoting enterprises to adopt advanced production technology and improve the technical level Industry experts pointed out that the standard is only a local standard, and hope that the national standard can be issued as soon as possible to guide the upgrading and development of the waterborne coating industry Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and
