Coating knowledge: how about coal tar epoxy coating

Core tips: epoxy coal tar pitch coating is widely used in petroleum, chemical industry, steel, coal, shipbuilding, electric power, city gas, tap water, heat supply, sewage treatment and many other aspects, which is well received by the construction unit, construction unit and design department Epoxy coal tar pitch coating is the most expensive raw material in the Three Gorges water conservancy project, and the epoxy resin accounts for the most cost The epoxy resin content should be between 25% and 30% (weight percentage), which is the best positioning of cost and quality If the epoxy resin is too low (less than 15%), the adhesion, mechanical properties and chemical resistance of the coating will be greatly reduced, which will affect the anti-corrosion of the coating 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: epoxy coal tar pitch coating is widely used in petroleum, chemical industry, steel, coal, shipbuilding, electric power, city gas, tap water, heating, sewage treatment and many other aspects, which is well received by the construction unit, construction unit and design department Epoxy coal tar pitch coating is the most expensive raw material in the Three Gorges water conservancy project, and the epoxy resin accounts for the most cost The epoxy resin content should be between 25% and 30% (weight percentage), which is the best positioning of cost and quality If the epoxy resin is too low (less than 15%), the adhesion, mechanical properties and chemical resistance of the coating will be greatly reduced, which will affect the corrosion resistance of the coating and cause the pipeline and equipment to be corroded in a short time But at present, the competition in the domestic market is based on the price Therefore, some manufacturers reduce the sales price by sacrificing the product quality, regardless of the national engineering quality In this way, the reputation of epoxy coal tar pitch will be seriously affected, and the excellent anticorrosive material which has been used for more than 50 years at home and abroad will be polluted The so-called epoxy coal tar pitch coating appears in the market The price is less than 12 yuan per kilogram Can the epoxy resin content of such low-cost epoxy coal tar pitch coating reach 25%, can the coating performance meet the standard requirements, can the equipment and pipes of the factory be protected properly, and can the user's investment be worth the money! The editor said: in order to maintain the excellent quality of epoxy coal tar pitch and make it last for a long time, he proposed that all kinds of domestic epoxy coal tar pitch production plants, anti-corrosion companies of epoxy coal tar pitch construction users and project investors should jointly control the quality of epoxy coal tar pitch coating and coating, and strictly follow the national standards for production, inspection and construction to ensure the quality of anti-corrosion coating, which is an old product with a long history Products carry forward Everbright 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,
