Phenolic insulation board quality
at present, the fire caused by thermal insulation material, resulting in personnel casualties and property caused great damage to people's life, so when in the selection of insulation materials we must pay attention to observe the quality of the insulation board, so how to identify the quality of the phenolic insulation board? | and, as a kind of phenolic insulation board is also a kind of exterior wall thermal insulation material, choose insulation materials should pay attention to what issues?
1. Production is a major with hair bubble production, general use of this kind of method to produce the product density is relatively low, easy to brittle, prone to slag pulverization or off.
2. Additionally one kind is assembly line production, for modified phenolic keep warm plate, is the phenolic resin and foaming process was improved, production out of the modified phenolic insulation board to a certain extent, overcomes the drawback of slag powder melt itself, thus modified phenolic insulation board density generally in more than 55 kg.
3. In addition to the above method to identify, we can also observe the appearance of the phenolic insulation board, by hand press density, toughness break see insulation board, rubbing it whether slag powder melt and other methods to identify the quality of the phenolic wall thermal insulation board.
4. In addition to buy insulation board must choose normal manufacturer when the choose and buy, because this kind of normal manufacturer, they produce a product is strictly controlled by the department of quality supervision. Product quality problems of this kind of normal manufacturer produce relatively less.
5. Phenolic insulation board should pay attention to during the construction of edge horn, ensure the intact after the wall.
