Coating knowledge: how to control the quality of solventless epoxy floor coating

The key points are as follows: (1) the quality control of solventless epoxy floor coating is much more strict than solvent epoxy coating After each construction, carefully observe the surface state, whether the coating is uniform, whether there are pores, coarse particles, curing speed of the coating, etc Problems found shall be solved in time It is necessary to operate strictly according to the thickness of each coating and curing conditions specified in the construction to avoid quality accidents during construction (2) The quality control of surface treatment before coating shall be based on the surface treatment requirements of the coated object, and adopt scientific and effective treatment methods to thoroughly remove the oil dirt, rust and impurities on the surface of the coated object 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: (1) quality control in the construction process solventless epoxy floor coating construction requirements are much more stringent than solvent epoxy coating After each construction, carefully observe the surface state, whether the coating is uniform, whether there are pores, coarse particles, curing speed of the coating, etc Problems found shall be solved in time It is necessary to operate strictly according to the thickness of each coating and curing conditions specified in the construction to avoid quality accidents during construction (2) The quality control of surface treatment before coating shall be based on the surface treatment requirements of the coated object and adopt scientific and effective treatment methods to thoroughly remove the oil dirt, rust and impurities on the surface of the coated object, so as to ensure the surface of the coated object is clean and dry In particular, the surface of the coating should have a certain roughness, which plays an important role in ensuring the coating quality of solventless epoxy coating (3) After the final quality inspection coating construction procedure is completed, the coating quality shall be comprehensively inspected according to the quality standard Test the hardness, thickness, adhesion, surface state, gloss and other quality indicators of the coating When it is found that the film has defects such as bubble, crack, wrinkle and shrinkage cavity, effective remedial measures shall be taken, otherwise the protection purpose cannot be achieved In order to ensure the practical quality of solventless epoxy coating products, it is necessary to be familiar with the coating technology Due to some improper operation in the coating process, various diseases or abnormal phenomena of the coating will occur There are many factors related to the formation of film defects, one of which may be caused by several factors In practice, it is often found that pathological repeatability and reproducibility are not consistent Generally, the causes of the defects are related to coating, coating process, drying and solidification, construction method, surface state of the coated object, coating equipment and environment, etc., and the preventive measures should also be formulated according to the main factors that cause the defects, Paint coating, coating process, decoration knowledge and decoration effect drawing of fire retardant coating,
