In recent years, some large places in Nanning CityFireAll because of the use of fake and shoddy fire protection.DecorationMaterials and other reasons, resulting in increased losses. These fake and shoddy materials include inferior qualityfire retardant coatingProducts.
On March 11, the author witnessed the relevant experiments done by inspectors at the Guangxi Fire Product Quality Supervision and Inspection Station. The results showed that fake and inferior fireproof coatings cracked and fell off quickly due to heat, with almost no flame retardancy, while qualified fireproof coatings can be flame retardant for more than ten minutes.
At about 3 p.m. that day, in the laboratory of the inspection station,TechnologyThe personnel successively fixed the two boards coated with fake fire retardant coating and qualified fire retardant coating on the corresponding equipment, and the two samples were burned under the same test conditions to test the flame retardant performance of the true and false fire retardant coating.
Wang Chunjiang, director of Guangxi fire product quality supervision and inspection station, said that when the surface of wood board coated with qualified fire retardant coating is on fire, the fire retardant coating can rapidly foam and expand in a short period of time, and form a uniform and dense honeycomb or spongy carbonaceous foam layer, isolating the flame from the wood board, preventing or delaying the combustion, thus playing a good protective role for combustible wood board. In general, qualified fire retardant coatings can be flame retardant for more than 15 minutes. Unqualified fire retardant coating due to noflame retardantOr flame retardant is very few, when the fire surface is exposed to fire, it will not foam and crack directly, and there will be a large number of scattered slag, which is not flame retardant or very poor flame retardant.
It is understood that counterfeitfireproof materialAnd the price of qualified fireproof materials is doubled or even several times. While severely cracking down on the illegal activities of manufacturing and selling counterfeit products, the fire department has issued a coup to identify the authenticity of fireproof coatings:
1. carefully check the package of fireproof coating to see if there is any mark, manufacturer's name, address and contact number on the package, and the package of qualified fireproof coating is indicated. Check whether the packaging barrel has been pried traces to prevent the purchase of fake fireproof coating in old barrels; Check whether the handwriting on the package is clear and the handwriting on the package of qualified fireproof coating is clear.
Second, when purchasing fire retardant coating, check whether it has a national levelFire FightingConformity inspection report issued by quality inspection center.
3. samples were taken for fire testing.
