After testing, when the surface of the wooden board coated with a qualified fireproof coating is exposed to fire, the fireproof coating can quickly foam and expand in a short time, and form a uniform and dense honeycomb or sponge carbonaceous foam layer to isolate the flame from the wooden board. It can prevent or delay the combustion to protect the combustible wood board. Under normal circumstances, qualified fire retardant coatings can be flame retardant for more than 15 minutes.
Unqualified fire retardant coatings have no flame retardant or very few flame retardants. When the fire surface is exposed to fire, it will not foam and crack directly, and a large amount of slag will be scattered. The flame retardant or flame retardant is poor.
It is understood that the price of counterfeit fireproof materials and qualified fireproof materials is double or even several times. The fire department issued a coup to identify the authenticity of fire-resistant coatings while cracking down on illegal activities in making and selling fake fakes:
First, carefully check the packaging of fireproof coatings to see if there is a label, manufacturer name, factory address, and contact phone number on the packaging. The qualified fireproof coatings are marked on the packaging; Counterfeit fireproof paint; check whether the handwriting on the package is clear and the handwriting on the qualified fireproof paint package is clear;
2. When purchasing fireproof coatings, check whether there is a qualified inspection report issued by the national fire quality inspection center.
3. Obtain samples for fire resistance test.
