Coating standard: Test Method for adhesion of epoxy floor coating

Core tip: epoxy floor coating belongs to surface coating type floor coating products, and the adhesion of floor coating directly affects the quality of epoxy floor Poor adhesion of epoxy floor coating may cause coating bulge or even fall off, so how to test whether the adhesion of epoxy floor coating meets the standard? The adhesion test of epoxy floor coating can be divided into three steps: 1 Grid First of all, use the special scriber for floor paint to draw small squares on the floor paint test pieces horizontally and vertically Pay attention to the control force when delimiting The blade must penetrate the floor paint coating to reach the base surface 2 Stick on adhesive tape Paste the tape at the place marked just now and press 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: epoxy floor is a surface coating type floor coating product, and the adhesion of floor coating directly affects the quality of epoxy floor Poor adhesion of epoxy floor coating may cause coating bulge or even fall off, so how to test whether the adhesion of epoxy floor coating meets the standard? The adhesion test of epoxy floor coating can be divided into three steps: 1 Grid First of all, use the special scriber for floor paint to draw small squares on the floor paint test pieces horizontally and vertically Pay attention to the control force when delimiting The blade must penetrate the floor paint coating to reach the base surface 2 Stick on adhesive tape Paste the tape at the place marked just now and compact it to make the tape fully stick to the floor paint test piece 3 Remove the adhesive tape and observe the paint quality After the tape is compacted, tear it off with force, and observe the paint quality falling off on the floor paint test piece The adhesion of epoxy floor can be divided into four grades of 0-3, of which grade 0 has the best adhesion If the adhesion exceeds grade 1, it can be considered that the adhesion of the epoxy floor is not up to standard Please refer to corresponding documents for specific classification If it is not possible to accurately determine the adhesion level of the epoxy floor paint, the impact rate of the epoxy floor paint test piece can be estimated to determine whether the adhesion of the floor paint test piece is up to the standard If the influence of floor coating is less than 5%, the adhesion of epoxy floor coating is up to standard If the floor paint coating is affected by more than 5%, the adhesion of the epoxy floor paint test piece is not up to standard As mentioned above, insufficient adhesion of floor coating may lead to peeling off of epoxy floor coating Peeling off of epoxy floor coating refers to the phenomenon that the floor coating film loses due adhesion to the substrate due to cracking, and the coating film shows small pieces or the whole peeling off surface under the effect of external force The degree of peeling off can be divided into: peeling off of small pieces with a diameter of less than 5mm is called mud carp peeling off; peeling off of large pieces is called peeling off; peeling off of pieces can be called peeling off; peeling off between coating and coating is called interlayer peeling off 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,
