Coating process: performance requirements of reflective insulation coating

Core tip: according to the industry standard JC / T 1040-2007 "thermal reflective and thermal insulation coating for external surface of building" According to the different dispersing media of the product, it can be divided into two types: water-based and solvent-based The technical requirements of building reflective insulation coating shall meet the requirements in the table below Construction industry standard JC / T 1040-2007 quality requirements for building reflective thermal insulation coating Performance index project performance index WS 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: according to the industry standard JC / T 1040-2007 "thermal reflective thermal insulation coatings for external surfaces of buildings" According to the different dispersing media of the product, it can be divided into two types: water-based and solvent-based The technical requirements of building reflective insulation coating shall meet the requirements in the table below Construction industry standard JC / T 1040-2007 quality requirements for building reflective thermal insulation coating performance index project performance index w s Container state after mixing without hard block, agglomeration, after mixing in a uniform state without hard block, agglomeration, in a uniform state construction brush coating two barrier free brush coating two barrier free film appearance without pinholes, sagging, even coating No pinhole, sagging, even application, low temperature stability, no hard block, agglomeration and separation drying time (surface dry) / h 22, alkali resistance 48h, abnormal water resistance 96h, abnormal washing resistance 168h / time 2000 5000, stain resistance (white and light color) 20 10, coating temperature resistance (5 cycles) no abnormal solar reflectance (white) 0.83 0.83 Hemispherical emissivity 0.85 0.85 bending resistance /mm - 2 tensile properties tensile properties /MPa elongation at break /% 1.0100 - resistance to artificial aging appearance pulverization, grade discoloration (white and light color) / grade solar reflectance (white) hemispherical emissivity 400H no blistering, no peeling, no crack 120.81 0.83 400H no blistering, no peeling, no crack 120.81 0.83 impermeability 0.3MPa, 30min impervious - water vapor permeability / (g / ㎡ · s · PA) 8.0 × 10-8 - home of coatings is focused on coatings, diatom mud, paint coating, coating process, news and coating of fire retardant coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
