Distinguish between phenolic insulation board quality way _ phenolic insulation board, phenolic board manufacturer
1. Is used when producing a great bubble produced, usually use this kind of way to produce the goods density is relatively low, simple and crisp, easy pulverization slag may be off.
2. The other is a kind of assembly line production, for modified phenolic keep warm plate, is the phenolic resin and foaming technique were improved, the production of modified phenolic insulation board must extent overcome the shortcomings of slag powder melt, and then modified phenolic insulation board density is usually over 55 kg.
3. In addition to the above way, we can also go to survey the appearance of the phenolic insulation board, by hand press density, toughness break see insulation board, conflict with the hand is it powder melt slag etc method to identify the quality of the phenolic wall thermal insulation board.
4. Other procurement phenolic insulation board must be selected in the standard manufacturer of choose and buy, because this kind of specifications of the manufacturer, their output goods are part under strict quality supervision and control. Manufacturer to produce this kind of specification of the goods quality problem is relatively less. http://www。 fenqbwb。 com
