Paint knowledge | standard for thermal insulation coating of roof insulation materials

Core tip: the standard of cooking oil, which is most closely related to our lives, is extremely sad There is no standard of gutter oil in our country The public can't avoid gutter oil and have to eat even if they don't want it, even if they know the harm of gutter oil The standards of cooking oil are all the same Think of the standards of other industries! Nowadays, there are more and more brands of thermal insulation coating in the market The general insiders may not know exactly how to distinguish the authenticity of thermal insulation coating, let alone the formulation of some brands of thermal insulation coating standards Let's take a look at the standards of roof thermal insulation materials following the small compilation First, solvent based thermal insulation coating: This kind of coating is sold on the market about 22 per square meter- 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 Paint Home News: the standard of cooking oil, which is most closely related to our lives, is extremely sad There is no standard of gutter oil in our country The public can't avoid gutter oil and have to eat even if they don't want it, even if they know the harm of gutter oil The standards of edible oil are all the same, but we can think of the standards of other industries! Nowadays, there are more and more brands of thermal insulation coating in the market, and the general insiders may not know exactly how to distinguish the authenticity of thermal insulation coating, let alone the formulation of some brands of thermal insulation coating standards Let's follow the small edition to see the standards of roof thermal insulation materials! 1、 Solvent based thermal insulation coating: This kind of coating is about 22-25 per square meter on the market, while fluorocarbon thermal insulation coating material is about 45 per square meter on the market Solvent based thermal insulation coating not only contains the same ingredients as oil-based coating, some brands call it contains fluororesin ingredients for high price, but also some brands say that they add some metal powder This type of coating has no reflection on the infrared ray of the sun at all Yes, the reflection of the sun depends on the smooth surface and white color The oily coating is also resistant to dust, but its weather resistance is better than the water-based coating The insulation function of this kind of coating will be lost after a period of time The construction process is complex, not environmentally friendly and has a strong taste, while the price of the fluorine containing resin is higher 2、 The water-soluble thermal insulation coating has the same ingredients as the ordinary white exterior wall, while most brands claim to contain hollow glass bead ceramics Composition, the barrier effect of this kind of coating on heat transfer comes from the reflection of white to sunlight and hollow glass bead ceramics The price of this kind of coating is generally about 15 yuan per square meter As we all know, the heat generated by white to sunlight and its reflection function are slightly smaller, only part of sunlight can be reflected, which is just like that a car is better than black in hot summer A little white car, when it is exposed to the sun for a period of time, when you touch its surface, the temperature of the surface will be hot outside the hand and will also enter the car The principle of hollow glass bead is the same Although it has a certain barrier effect on the sun, it will also be introduced into the car when the temperature reaches a certain value This kind of coating has no function of reflecting the infrared ray in the sun, and has almost no function of protecting the ultraviolet ray in the sun That is to say, customers only use the effect of one year and spend tens of yuan At the same time, the effect of thermal insulation function of one year is less than 50% at most 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,
