First, how to correctly choose flame retardant materials
The appearance of fire retardant coatings is very similar to that of ordinary coatings, and it is difficult to distinguish them from each other in appearance, but consumers still have ways to choose high-quality and suitable fire retardant coatings.
1, check the fire resistance of fire retardant coatings.
It is required to check the fire resistance of the coating when purchasing. Intumescent fire retardant coatings will bubble and expand a lot when burning in strong fire, and the surface will gather and bulge, and there will be no burning loss in a few minutes, while fake and shoddy fire retardant coatings will basically not bubble, and a large amount of slag will be scattered, and the wood substrate will be burned quickly.
2. Understand the combustion performance of fire retardant coatings.
According to the national standards, the combustion performance of fire retardant coatings can be divided into first-class and second-class besides meeting the fire resistance requirements. Under the specified experimental conditions, the fire resistance time of the first-class fire retardant coating is not less than 20 minutes, and the heat resistance time of the second-class fire retardant coating is not less than 10 minutes. Users should pay attention to the distinction when choosing, to prevent enterprises from shoddy and failing to achieve fire fighting effect.
Don't be greedy and cheap when buying products.
At present, domestic enterprises produce fire-retardant coatings with secondary fire-retardant performance, and the cost price is more than 8000 yuan/ton. If the sales price is lower than this, the quality is worrying. So you can't be greedy and cheap when buying, otherwise you will buy products with unqualified quality and environmental protection.
4. Check the certificate and choose the brand
At present, the fire-retardant coatings are subject to the type approval system of fire-fighting products, and the fire-retardant coatings sold in the market should have the national fire-fighting product type approval certificate and type inspection report. In addition to checking whether the product has a complete national inspection certificate, choosing a brand product with reputation protection can make home fire prevention more secure.
Finally, fireproof paint is a protective material for flammable materials on furniture, but fireproof materials also have their own limits. If it exceeds this limit, it will still make the furniture catch fire and cause a fire, but the fire retardant coating can slow down the ignition time of the furniture and win valuable time for people to find the fire. Professionals predict that fire retardant coatings will become more and more popular in the future, and more people will pay attention to safety and fire prevention in home decoration. Therefore, it is the key to create a safe and comfortable home to correctly choose the types of fire-retardant coatings and select highly skilled decoration workers.
Second, the relationship between coating thickness and fire resistance of fire retardant coatings
Is the thicker the fire retardant coating, the better its fire resistance? Generally speaking, it is like this. For non-intumescent fire retardant coatings, flame spread is prevented by their own flame retardancy and incombustibility. Therefore, the thicker the coating, the thicker the glaze formed at high temperature, and the heat insulation effect of the fire retardant coating will also be improved. For intumescent fire retardant coatings, the thicker the coating, the thicker the foam layer will be when it expands and foams in case of fire. The more groups such as [NO] and [NH3] are decomposed from some nitrogen-containing fire retardant coatings, they will combine with organic free radicals and interrupt the chain reaction. Therefore, in terms of improving fire resistance, the thicker the coating, the better.
