Coating technology: exterior wall latex paint testing technology

Core tips: several routine tests: 1 State in the container: no hard block, uniform state after mixing; 2 Constructability: brush and paint two layers without obstacles; 3 Film appearance: no pinholes and sags, even film; 4 Surface dry time: ≤ 2 hours; 5 Water resistance: no abnormality in 96 hours 6 Alkali resistance: no abnormality in 48 hours 7 Washability: ≥ 500 times, the test plate does not expose the bottom plate; 8 Contrast ratio: ≥ 0.87; test basis: GB / t9755-200 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: several routine tests: 1 State in the container: no hard block, uniform state after mixing; 2 Workability: no barrier for two coats of brush coating; 3 Appearance of film: no pinhole and sagging, even film; 4 Surface drying time: no more than 2 hours; 5 Water resistance: no abnormality at 96 hours; 6 Alkali resistance: no abnormality at 48 hours; 7 Washability: ≥ 500 times, the test panel does not expose the bottom plate; 8 Contrast ratio: ≥ 0.87; test basis: GB / t9755-2001 standard enterprise can carry out its own full-scale test or entrust relevant departments to test coating home, which focuses on coating, diatom mud, paint coating, coating technology, fire retardant coating news information and coating, diatom mud, paint coating, coating technology, Decoration knowledge and effect drawing of fireproof coating,
