Coating process: testing process of facing fire retardant coating

Core tip: physical and chemical performance requirements: project refers to There is no caking in the state marked in the container, and the fineness is uniform after mixing / μ m ≤ 90, surface dry ≤ 5, dry ≤ 24, adhesion / grade ≥ 3, flexibility / mm ≤ 3, impact strength / N · cm ≥ 196, water resistance (24h), no foaming, no powder dropping, light loss and discoloration allowed (48h), moisture and heat resistance (48h), no foaming, no powder dropping, light loss and discoloration allowed 1 The raw materials used in the manufacture of fire retardant coating shall be inspected in advance 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: physical and chemical performance requirements: no caking in the state of the project index in the container, uniform state fineness after mixing / μ m ≤ 90 surface dry ≤ 5 solid dry ≤ 24 adhesion / grade ≥ 3 flexibility / mm ≤ 3 impact strength / N · cm ≥ 196 water resistance (24h), no foaming, no powder falling, light loss and discoloration (48h) No blistering, no powder dropping, slight loss of light and discoloration allowed 1 Raw materials used for fire retardant coating shall be inspected in advance, and benzene solvent shall not be used; 2 Fire retardant coating shall be uniform liquid or thick, paste like fluid within the specified storage period, without hardening, skinning or star pigment (filler) precipitation; 3 It is allowed to layer slightly, but it can become a uniform and suspended system after mixing; 4 The fireproof coating can be easily applied by any one or more methods of brushing, spraying, roller coating or scraping, and can be dried and solidified under normal natural environment conditions; 5 There is no obvious concave convex or stripe mark on the surface after film forming, no peeling, pinhole, bubble, craze, spot or color separation phenomenon, which can form a flat finish; 6 The fire retardant coating shall have no pungent smell after the coating is dry Fire performance requirements: project index class I and class II fire resistance time / min ≥ 20 10 flame propagation ratio ≤ 25 75 mass loss / g ≤ 5.0 15 carbonization volume ≤ 25 75 paint home is focused on coating, diatom mud, paint coating, coating process, news information and coating of fire retardant coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
