    Core tip: compared with the general paint, the physical properties of fire retardant paint are basically the same The difference is that after it is dried, the film itself is not easy to burn In case of fire, it can delay the flame burning to the combustible of the paint, and has certain fire performance According to the test: apply the general paint and fireproof paint on the board respectively After drying, bake the board with the same flame The board with the general paint will burn together with the paint in less than 2 minutes The board with the non expansion fireproof paint will only appear smoldering after 2 minutes, and it will be extinguished immediately after 30 seconds standing; Even if the wood board is baked for 15 minutes, there is no smoldering phenomenon Thus it can be seen Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: compared with general paint, fire-proof paint is basically the same in physical properties The difference is that after it is dry, the film itself is not easy to burn In case of fire, it can delay the flame burning to the combustible of the paint, with certain fire-proof performance According to the test: apply the general paint and fireproof paint on the board respectively After drying, bake the board with the same flame The board with the general paint will burn together with the paint in less than 2 minutes The board with the non expansion fireproof paint will only appear smoldering after 2 minutes, and it will be extinguished immediately after 30 seconds standing; Even if the wood board is baked for 15 minutes, there is no smoldering phenomenon It can be seen that once a fire occurs, the fire can be prevented from spreading and the surface of the object can be protected by applying the fire-proof paint on the surface of the object, so as to gain valuable time for the fire fighting Why can fireproof paint prevent fire spreading in a certain period of time According to the analysis of three kinds of fire-proof paint, the reasons are as follows: expansion type: the resin in the fire-proof paint adopts the foaming substance sodium silicate or the foaming agent boric acid, which will change when encountering heat, make the paint film expand and bubble, form a hard empty shell, and increase the distance between the fire source and the material surface Nonexpansive Type: this kind of fireproof paint uses perchloroethylene, chlorinated rubber, vinyl acetate, vinyl chloride copolymer and other substances as resin When they meet the flame, they are heated and decomposed to produce nonflammable gases, such as chlorine, carbon dioxide, etc., dilute the surrounding flammable gases and weaken the fire Sometimes some chemicals such as ammonium carbonate, ammonium chloride and ammonium phosphate are added into the paint, which will also produce non combustible gas in case of heat, but the addition of these chemicals often has a certain impact on the physical properties of the paint film, so it must be used reasonably Expansion inert gas type: this kind of fireproof paint is made of tetrachlorophthalic anhydride alcohol resin When heated, it can not only make the paint film expand and froth, but also produce non combustible gases such as chlorine It has both the above two functions, so it has better effect and longer fire resistance time In addition, the pigments used in the fire retardant paint should also be able to block and isolate heat sources, such as asbestos powder, antimony white powder, mica powder, titanium white powder, etc Antimony white powder, which has strong reflection ability to infrared ray, can reflect heat when meeting flame, and is widely used in fireproof paint As a new type of paint, fire retardant paint also has some disadvantages, such as high cost, some kinds of fire retardant paint physical properties are not ideal and so on But these shortcomings will be overcome through practice to meet the needs of fire prevention 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,
