All construction coatings have passed ISO9001 Paint Home News: home life, safety is the most important In modern home decoration, the use of various flammable materials is becoming more and more common, so it is very important to do a good job in fire prevention Now a very common way to deal with fire is to use fire retardant coating Fireproof coating is a kind of material which can effectively protect the base material and prevent combustion There are many kinds of fire retardant coatings on the market If you want to select high-quality products, you need to make necessary knowledge preparation before purchase Part 1: the first step to purchase the fireproof material is to understand that the fireproof coating is a special coating used to coat the surface of base material, reduce the flammability of the surface of the coated material, block the rapid spread of fire, and improve the fire resistance of the coated material The fireproof coating has a good protective effect on the base material, which is suitable for the place where the visible open fire such as kitchen and the inflammable board such as wooden cabinet and floor are installed In case of fire, fire retardant coating can win time for fire fighting and personnel evacuation 1 Fire retardant coating is composed of base material (i.e film-forming material), pigment, common coating assistant, fire retardant assistant and dispersion medium In addition to fire retardant additives, other coating components play the same role in coatings as in ordinary coatings, but some have special requirements in performance and dosage Some solvent based fire-retardant coatings can burn in case of fire before construction In fact, the flammable liquid solvent in the fire-retardant coating is burning, while the base material, fire-retardant additives and other substances of the fire-retardant coating will not burn Because solvent based fire retardant coating takes organic solvent as solvent, once these fire retardant coating leaks out of the barrel, it is easy to cause fire The fireproof coating applied on the base material can play the role of fire resistance and heat insulation only after the solvent has evaporated 2、 The classification of fire-retardant coatings can be divided into several categories according to various classification methods, such as the parts used, the film-forming materials, the solubility and the fire-retardant principle According to the function, function and national standard requirements of fire retardant coating, the most suitable classification is: structural fire retardant coating and facing fire retardant coating Structural fire retardant coating is used for fire retardant coating of steel structure, concrete structure and wood structure, that is to say, it is mainly used as protective material of non combustible components The coating of this kind of fire retardant coating is relatively thick, with small density, low thermal conductivity and excellent heat insulation performance Facing fire retardant coating is generally used as the protective material of combustible base material, such as the surface of wood, home appliance, cable and other decoration materials, it has certain decorative and fire resistance Part 2: to avoid mistakes, choose the right fire retardant coating in different spaces and different materials have different requirements on the performance of the fire retardant coating Therefore, when purchasing the coating, you can ask experienced shop salesmen to use the right fire retardant coating in the right place, so as to achieve the best fire protection effect Misunderstanding 1 Use wood structure fire retardant coating on steel structure Because wood structure fire retardant coating and steel structure fire retardant coating cannot be identified by naked eyes, consumers must know the detailed properties of fire retardant coating when purchasing If the fireproof coating of wood structure is used for steel structure, its adhesion will be greatly reduced, and it is easy to fall off, so the fire safety cannot be guaranteed 2 There are two kinds of fire retardant coatings for steel structure, solvent type fire retardant coating and water-based fire retardant coating From the perspective of adhesion, the solvent type is greater than the water-based, so the solvent type fire retardant coating should be used for outdoor steel structure, and the solvent type or water-based fire retardant coating can be used for indoor steel structure The fire-proof coating produced by some domestic manufacturers will decompose toxic gases in case of fire If this kind of coating is used in fire-resistant electrical products, toxic gas will be released in case of fire For example, G60 perchloroethylene fire retardant coating, which has been eliminated, will decompose toxic chlorine in case of fire, so it can not be selected Part3: the appearance of the skillful fire retardant coating is very similar to that of the common paint, which is difficult to distinguish from the appearance, but consumers still have a way to choose the high-quality and appropriate fire retardant coating 1 Check the fire resistance of fire retardant coating When purchasing, it is required to check the fire resistance of the coating When the intumescent fire retardant coating is burned by a strong fire, it will foam and expand in a large amount, the surface will gather and bulge, and there will be no burning loss in a few minutes, while the fake and inferior fire retardant paint will not foam basically, there will be a large number of scattered slag, and the wood base material will also burn and damage in a short time 2 According to the national standard, the combustion performance of fire retardant coating can be divided into two levels: first level and second level Under the specified experimental conditions, the fire resistance time of the first level fire retardant coating shall not be less than 20 minutes, and the heat resistance time of the second level fire retardant coating shall not be less than 10 minutes Users should pay attention to distinguish when choosing, to avoid that enterprises can not achieve the effect of fire protection 3 Don't be greedy for small and cheap products At present, domestic enterprises produce fire-retardant coatings with fire-retardant performance of grade II, and the cost price is more than 8000 yuan / ton If the sales price is lower than this, the quality is worrying Therefore, when purchasing, we should not be greedy for small and cheap products, or we will buy products with unqualified quality and environmental protection 4 At present, the fire-fighting product type approval system is implemented for the inspection of qualification certificate and selection of brand The fire-fighting coating sold on the market shall have the national fire-fighting product type approval certificate and type inspection qualification report In addition to checking whether the product has a complete national inspection certificate, selecting brand products with credibility guarantee can make home fire protection more secure Part 4: key points for construction of detailed fire retardant coating the quality of construction of fire retardant coating also has an impact on the fire performance of materials, so it is necessary to pay attention to the coating quality of fire retardant coating The coating methods of different fire retardant coatings are slightly different, but the basic construction points are the same Before coating the fireproof coating, the base material shall be well prepared for surface treatment to keep the surface clean and flat In particular, the steel structure base material shall be derusted for anti-corrosion treatment before applying fire-retardant coating It is better to brush antirust paint to avoid new rust before spraying fire retardant coating Dust and dirt on the surface shall be removed before spraying 2 Meet the requirements of fire-retardant coating construction environment when the environment temperature is 0 to 40 ℃, the substrate temperature is 5 to 45 ℃, and the relative humidity of air is not more than 90% At the same time, keep the air circulation in the construction site, with the wind speed no more than 5m / s and no ventilation Outdoor operation or condensation on the surface of construction components is not suitable for construction 3 When the fire-retardant coating is applied mainly by brush, it can also be applied The thickness of each coating is 10 mm to 20 mm, and the second construction shall be carried out after the surface is dry The time interval of each coating shall be subject to the coating not touching hands until the required thickness Local repair shall be done by hand 4 After the coating maintenance and coating storage, the curing and maintenance of fire retardant coating shall be done well The newly sprayed coating shall be protected from rain and direct sunlight The coating will cure within 48-96 hours under normal temperature The storage temperature of the coating is 4-40 ℃, which can not be stored outdoors or exposed to the sun The validity period of the fireproof coating product is generally half a year Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology,
