With the improvement of people's living water products, indoor decoration choices are not only toxic, but also beautify the environment. Fireproof coatings are the common pursuit of living and living environment. Fire-retardant coatings are special coatings used on the surface of flammable substrates to reduce the flammability of the surface of the coated material, to retard the rapid spread of fire, and to improve the fire endurance of the material being coated. On the occasion of the 33rd “International Consumer Rights Dayâ€, the fire-fighting sergeant in Loudi City, Hunan Province, teaches you a few tricks to uncover the “veil†of fire-retardant coatings on the market.
1. The appearance of fireproof coating is very similar to that of ordinary paint. It is difficult to distinguish from the appearance, and it is difficult to check the quality of fireproof paint on site. Consumers should pay attention to distinguishing fire-retardant coatings and ordinary coatings when choosing, to avoid the need for enterprises to shoddy and fail to achieve fire protection effect, so as to prevent safety hazards.
2, do not covet cheap when buying paint, must choose a well-known brand of products. The "fireproof coatings" on the market are mixed, consumers must shop around when buying. Don't be superstitious about the "green" on the coatings. Be careful to see the quality inspection report of the products; observe the seams of the iron barrels. There is no rust or leakage; pay attention to the complete indication on the iron drum to prevent the purchase of counterfeit “fireproof coatingâ€.
3. When purchasing fireproof coatings, you can also check whether the product has the qualified inspection report issued by the national fire quality inspection center. At present, fireproof coatings implement the type approval system for fire protection products. The fireproof paints sold on the market should have the national fire protection product type approval certificate and the type inspection qualification report.
4. When the qualified fireproof coating is burned by a strong flame such as a blowtorch, it will foam and expand a lot, the surface will gather and bulge, and there will be no burning phenomenon within a few minutes, while the fake and shoddy fireproof coating will not foam at all, and there will be a large amount of In the case of scattering of slag, the wood substrate will also quickly burn and break.
5. According to national standards, in addition to meeting the fire resistance requirements, the combustion performance of fire retardant paint is divided into first and second grades. Under the specified experimental conditions, the first-class fireproof paint has a flame resistance time of not less than 20 minutes, and the secondary fireproof paint has a heat resistance time of not less than 10 minutes.
Article 24 of the Fire Protection Law of the People's Republic of China clearly stipulates that it is prohibited to produce, sell and use unqualified fire-fighting products and fire-fighting products that have been eliminated by the state. In the process of purchasing or using fire-fighting products, the public may find that there are counterfeit or shoddy or fire-fighting violations. You can call the public security fire department's fire hazard report and complaint phone number "96119" to report it. The public security fire department will conduct the acceptance check at the first time.
