Coating standard: Guangdong implements the new coating standard to guide the development of heavy-duty anticorrosive coating

Core tip: Recently, Guangdong Provincial Bureau of quality and technical supervision officially approved and issued the standard of waterborne polyurethane anticorrosive coating (two-component), which will be implemented from March 31 The implementation of the standard will improve the construction of waterborne product standard system in the coating industry, which is conducive to the development of anticorrosive coatings suitable for the market requirements, especially heavy-duty anticorrosive coatings, and guide the development of waterborne anticorrosive coatings It is understood that at present, the R & D level of heavy and overweight anticorrosive materials in Guangdong Province is relatively low, high-quality products are insufficient, low-quality products are in oversupply, and the production of heavy anticorrosive coatings for ships with anticorrosive effect of more than 15 years Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: Recently, Guangdong Provincial Bureau of quality and technical supervision officially approved and issued the standard of waterborne polyurethane anticorrosive coating (two-component), which will be implemented from March 31 The implementation of the standard will improve the construction of waterborne product standard system in the coating industry, which is conducive to the development of anticorrosive coatings suitable for the market requirements, especially heavy-duty anticorrosive coatings, and guide the development of waterborne anticorrosive coatings It is understood that at present, the R & D level of heavy and overweight anticorrosive materials in Guangdong Province is relatively low, high-quality products are insufficient, and the supply of low-quality products exceeds the demand The production and R & D strength of heavy anticorrosive coatings for ships with anticorrosive effect of more than 15 years needs to be strengthened At the same time, the coating is restricted by the environment and climate, which requires high construction, and the existing supporting facilities cannot keep up with it At present, the national, local and industry has not yet issued a series of standards for waterborne anticorrosive coating products In accordance with the provisions of the measures for the administration of industrial product standards, all the specific industrial product executive standards not specified shall refer to and implement the relevant standards of the integrated product system However, because the product standard system of anticorrosive coating (solvent type) fails to reflect some main indicators under the product system of waterborne anticorrosive coating and cannot ensure the quality of waterborne anticorrosive coating products, there is no set of quality indicators for this kind of coating and the promotion of products is weak The standards issued this time are specially for waterborne anti-corrosion coating products According to the actual situation of waterborne polyurethane anti-corrosion coating (two-component) products used for metal surface characteristics, with reference to the chemical industry standards of solvent polyurethane coating (two-component), and combined with the actual situation of Guangdong waterborne anti-corrosion coating industry This standard was proposed by Guangdong quality and Technical Supervision Bureau, and Guangdong coating industry association organized manufacturers in the industry to participate in the preparation The standard specifies and requires the classification, requirements, test methods, inspection rules, marks, packaging and storage of waterborne polyurethane anticorrosive coating (two-component), which has strong guidance and practicability 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,
