Phenolic insulation board insulation principle and use

The phenolic insulation board is made of phenolic foam, which is a new type of non-combustible, fireproof, low-smoke and heat-insulating material. The closed-cell rigid foam is made of phenolic resin added with foaming agent, curing agent and other additives.

Features are non-combustible, low smoke, and high temperature resistance. It overcomes the shortcomings of the original foam plastic insulation material flammable, smoke, heat deformation, retains the original foam insulation materials, light weight, easy construction and so on.

External wall insulation refers to the use of a certain fixed method (bonding, mechanical anchoring, adhesive mechanical anchoring, spraying, casting, etc.), and the insulation material with a relatively low thermal conductivity (better thermal insulation effect) is integrated with the building wall. An engineering practice that increases the average thermal resistance of a wall to achieve insulation or thermal insulation.

The fireproof and heat insulation board is made of refractory materials such as expanded perlite and expanded vermiculite as the main aggregate. Under the action of the reinforcing material and the binder, the fireproofing, heat preservation and heat insulation are integrated into the paste. Layer structure board.

Insulation principle: The closed-cell porosity of the foam concrete fireproof and heat insulation board is > 95%, and the high closed-cell rate reduces convection heat transfer, which is a condition of high heat insulation. The thermal conductivity of foamed concrete fire insulation board insulation board is basically the same as the thermal conductivity of polystyrene board, so it can meet the needs of building thermal insulation.
