Coating classification: fire protection and heat insulation principle of fire retardant coating

Core tip: the principle of fireproof and heat insulation of fireproof coating is to add different substances into the formulation of fireproof coating to prevent the combustion, mainly including the following categories: 1 Add various inorganic fillers Because inorganic fillers are incombustible and have low thermal conductivity, they can delay the heat transfer to the protected substrate 2 Add heat absorbing decomposable flame retardant, such as aluminum oxide, etc Because this additive can decompose after absorbing heat, it can effectively reduce the temperature 3 It can be released in hot condition 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 Coating home news: the fire insulation principle of fire retardant coating is to add different substances into the formula of fire retardant coating to prevent combustion, mainly including the following categories: 1 Add various inorganic fillers Because inorganic fillers are incombustible and have low thermal conductivity, they can delay the heat transfer to the protected substrate 2 Add heat absorbing decomposable flame retardant, such as aluminum oxide, etc Because this additive can decompose after absorbing heat, it can effectively reduce the temperature 3 Add flame retardants, such as halogenated compounds, that can release active gas compounds when heated These active compounds act on the formation and growth of free radicals in the gas flame 4 Select the additives that can release a large amount of inert gas during decomposition The existence of a large number of inert gases can dilute oxygen composition, produce gas shielding effect, make oxygen difficult to support combustion, and effectively improve the flame retardant effect 5 An additive that releases only heavy vapor without chemical change after being heated This kind of vapor can cover the combustible gas decomposed from the system, affect its normal exchange with air and oxygen, avoid the generation of flame and delayed combustion, and then play a role of flame retardant, so as to control the rapid spread of fire 6 Some coatings are also added with flame retardant of intumescent fire-retardant system 7 Some coatings are also added with low melting point materials that do not burn, such as glass powder 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,
