Phenolic plate a-class fire prevention materials application and heat preservation principle _ langfang three friends wall thermal insulation materials co. , LTD
phenolic plate a-class fire prevention materials how application in exterior wall, in the outer wall is how to play the efficacy of A fire? How is it heat preservation principle? A, heat preservation principle
phenolic plate a-class fire prevention materials obturator rate is %, high obturator rate reduce the convection heat transfer, is the prerequisite of high heat insulation. Its coefficient of thermal conductivity with polystyrene board the coefficient of thermal conductivity of basic quite, can meet the requirements of building thermal insulation.
no matter from its role, fire or heat preservation principle from it, we can see, this is a very suitable for application to construction of materials, energy conservation, environmental protection, non-toxic harmless, which is exactly what we need.
2, fire prevention function
fire insulation board is the expanded perlite, expanded vermiculite and other aggregate refractory materials as the main body, under the action of reinforcement materials and binder, with its fire prevention, heat preservation, heat insulation paste class board exterior wall adhesion layer structure. Exterior wall thermal insulation
3, the outer wall heat preservation refers to the adoption of a certain fixed way, Bonding, mechanical anchoring, paste + mechanical anchoring, spraying, casting, etc. ) , the low thermal conductivity, Heat preservation and heat insulation effect is better) The thermal insulation materials and building the wall fixed one, increasing the average thermal resistance of the wall, so as to achieve insulation or heat insulation effect of a kind of engineering practice.
phenolic foam material processed into phenolic plate, is applied to the external wall thermal insulation system, is a kind of insulation and refractory effect is very good material. And construction is convenient, lightweight, energy saving effect. Studies found that the material at the time of combustion, not like some foam material to produce large amounts of smoke, from this perspective, it is a environmental protection material.
