1) Exterior insulation of building exterior (thin plastering system, insulation and decoration integration, curtain wall system)
2) Central air-conditioning composite duct insulation (steel phenolic composite duct, double-sided aluminum foil phenolic composite duct)
3) Color steel sandwich panel area (active board room, decontamination, clean room, cold storage, cabinet room, etc.)
4) Roof insulation (residential roof, plant roof, roof insulation brick)
5) Low temperature cryogenic pipe insulation (LNG pipelines, LNG pipelines, hot and cold water pipelines)
6) Other areas that require thermal insulation The fires caused by insulation materials in China are frequent, resulting in casualties of people and property, causing huge losses to people's lives. Therefore, we must pay attention when selecting insulation materials. Observe the quality of the insulation board, then how to identify the quality of phenolic insulation board? As an exterior wall phenolic insulation board, it is also an exterior wall insulation material. What should be paid attention to when choosing insulation materials?
1. It is produced by using big bubble, and the product density produced by this kind of method is relatively low, easy to be brittle, prone to chalking or dregs.
2. The other is the assembly line production, which is used as a warming plate for the modification of phenolic resins. The phenolic resin and the foaming process have been improved. The modified phenolic insulation board has overcome the self-pulverization to some extent. The disadvantage of dregs, so the density of modified phenolic insulation board is generally above 55KG.
3. In addition to the above method identification, we can also observe the appearance of phenolic insulation board, press the density by hand, look at the toughness of the insulation plate, rub it by hand to determine whether it is powdered and dross, etc. Insulation board quality.
4. In addition to buying insulation boards must be selected from the regular manufacturers to buy, because of this type of regular manufacturers, their products are produced by the strict quality control department to control. The quality of the products produced by such regular manufacturers is relatively less
The thermal conductivity of phenolic foam is about 0.023 (about 1/2 of polyphenylene, the heat transfer coefficient of polyphenylene plate is about 0.042), the fireproof grade is non-flammable A grade (high temperature resistant to 150°C), and the price is similar to that of polyurethane. Polystyrene foams and polyurethane foams are flammable and do not withstand high temperatures and are being used by the fire department. Phenolic fireproof and heat insulation board can effectively solve the problem of building fireproof and heat preservation. Phenolic insulation board does not drips at high temperature, does not soften, has low smoke, does not spread flame, resists flame penetration, has excellent fireproof performance, and has good heat preservation and energy saving effect. , It combines excellent fireproof performance with good energy-saving effect and is suitable for exterior wall thermal insulation. Phenolic insulation board application form:
