Fire insulation board for test? What is the test?
Whatever insulation flame retardant experiment was carried out before the formal operation, fire insulation board is also not an exception, of course, that the fire insulation board to be fire retardant test before use, specific to what test? What are the content of the test? Learn together!
1, the thermal conductivity is the key of the thermal insulation material. Heat preservation performance is good or bad with a direct relationship between the coefficient of thermal conductivity.
2 need to look at whether flame retardant, fire insulation board first is to fire, flame retardant performance is good, quality is good. And as the material classification, classification standard, please refer to the gb 8624-2012, roughly combustible, non-combustible, flame retardant. The best quality of non-combustible.
3 the apparent density to a certain extent affect the coefficient of thermal conductivity of materials, and if the apparent density unqualified resulting in a decline in the physical properties of the thermal insulation material, affect the use.
4 fire insulation board of durability and resistance to impact, affect the service life of the insulation board.
Now fire frequency increases, also caused the people to fire insulation board's attention, so these are a must consider before formal operation test content.
