Phenolic insulation board is how to do is fire and heat preservation effect
phenolic foam material processed into phenolic insulation board, 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.
a, exterior wall thermal insulation
refers to the adoption of a certain fixed way (the heat preservation 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.
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.
3, heat preservation principle
phenolic insulation board a-class fire materials obturator rate is 95%, 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 fire prevention function, or from its heat preservation principle, we can see, this is a very suitable for application to the material in the construction engineering, energy conservation and environmental protection, non-toxic harmless, which is exactly what we need.
