Now many businesses will be their ordinary interior wall paint on the fire label, because the user has the demand, they will write the relevant services, the actual effect may not be ideal, so this paint can achieve what fire grade? The following powder coating powder manufacturer for you to introduce the classification.
There is no grade of fire protection for ordinary interior wall coatings. The grade that you often say may be the fire prevention of engineering building (fire prevention) grade, have commonly: First class fire prevention (fire prevention), Second class fire prevention (fire prevention), Third class fire prevention (fire prevention), Fourth class fire prevention (fire prevention).
Primary and secondary fire prevention accounts for the majority.
Common internal and external wall fireproof building coatings are divided into one, two, three levels, naturally is the best one-level characteristics. The quality of fire retardant building coatings is actually determined by the fire characteristics and physical and chemical characteristics of fire retardant building coatings.
Fire characteristics include flame retardant time, flame spreading ratio, weightlessness and carbonization volume, which can be obtained by carrying out experiments of large plate lighting method, tunnel construction lighting method and chamber lighting method respectively according to national industry standards. Physicochemical KEY properties include solid STATE composition, VISCOSITY, flexibility, IMPACT compressive strength, adhesion, dry time, and wear resistance. Its performance index is obtained according to the national industry standard experiment.
According to the thickness of the coating, the fireproof building coating of steel frame structure in the room can be divided into:
1. Fire retardant building paint for thin steel frame structure in the room
2. Fire retardant building coating for thin steel frame structure in the room
3. Thick steel frame structure fire retardant building paint in the room. Fire retardant building paint in addition to steel structure fire retardant building paint also decorative panel type fire retardant building paint, concrete fire retardant building paint, tunnel construction fire retardant building paint.
The exterior of the fire retardant interior wall coating is very similar to the ordinary architectural coating, which is difficult to identify from the exterior, and it is difficult to check the quality of the fire retardant paint on the spot.
Customers should pay attention to the identification of fire retardant architectural coatings and ordinary architectural coatings in the selection, to prevent the company from counterfeiting and shoddy, not up to the actual effect of fire maintenance, to prevent safety risks.
