General knowledge of coating: introduction of main construction methods of epoxy coal tar pitch paint

Core tip: mix and mix the coal tar epoxy paint well, then ripen it for 15-30min, and use it up within 4 hours The anti-corrosion coal tar epoxy paint shall be applied by brushing according to the site conditions The construction tools for painting operation shall be clean, and the cleaning and after use treatment shall be appropriate After steel derusting and passing the inspection, the primer and finish coat shall be applied When painting, the welding position of steel assembly shall be reserved as far as possible, with the reserved length of about 150 mm, so as to avoid the difficulty of root cleaning during welding and affect the welding quality The primer shall be applied immediately after the steel sand blasting is qualified Therefore, attention shall be paid to the influence of dust on the painting 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 Paint Home News: mix and mix the coal tar epoxy paint well, then ripen it for 15-30min, and use it up within 4 hours The anti-corrosion coal tar epoxy paint shall be applied by brushing according to the site conditions The construction tools for painting operation shall be clean, and the cleaning and after use treatment shall be appropriate After steel derusting and passing the inspection, the primer and finish coat shall be applied When painting, the welding position of steel assembly shall be reserved as far as possible, with the reserved length of about 150 mm, so as to avoid the difficulty of root cleaning during welding and affect the welding quality The primer shall be applied immediately after the steel sand blasting is qualified Therefore, attention shall be paid to the impact of dust on the painting, and the painting shall be as far away from the sand blasting area as possible or the sand blasting construction shall be suspended For the steel surface with a large degree of pit dust, putty should be mixed to make it flat If the paint recoating interval is too long, the paint surface needs to be roughened with emery cloth or grinding wheel before applying the next coat of paint The operation of coal tar epoxy paint shall be carried out in accordance with the material specifications and specifications delivered with the goods After the primer surface is dry, the first finishing coat shall be applied before curing, and after the finishing coat is dry, the second finishing coat shall be applied before curing During construction, the process flow is often continuous, so it is necessary to pay special attention to the painting interval time to ensure that the painting interval is between the minimum and maximum painting interval During site construction, the interval time of coating shall be determined according to the performance of coating and weather conditions When painting, the layers are crisscross, and each layer is repeated The time interval of painting shall meet the technical requirements of the coating, and the film thickness shall meet the design requirements During the drying process of the paint film, the surrounding environment shall be kept clean to prevent the surface of the paint film from being polluted 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,
