Can the roof insulation be filled with polystyrene board?
Phenolic Composites Class A Fireproof Insulation Boards. Its long-term use temperature is -250 ℃ to 150 ° C, fire, nonflammable, dripping in high temperature environment, no softening only surface carbonization. Thermal conductivity coefficient of only about 0.023W / mk phenolic insulation board, insulation performance is very good. Phenolic resin has the advantages of non-flammable, low thermal conductivity, good insulation, sound insulation, good weather resistance, service life of up to 30 years or longer. Has a uniform closed-cell structure, low thermal conductivity, thermal insulation properties, and quite superior to polystyrene foam polyurethane; in a very short period of time can be used for a suitable temperature range of -200 ℃ to 200 ℃, Long-term use, better than polystyrene foam and polyurethane foam (110 ℃); phenolic molecules contain only carbon, hydrogen, oxygen atoms (80 ℃), by thermal decomposition, 140 ℃ to 160 ℃ C, in addition to produce a small Of the amount of CO gas, will not produce other toxic gases, lack of storage and fattening fat plug Dan Dan Dan 5.0% of the maximum smoke density. 25mm thick phenolic foam board can withstand 1500 ℃ flame spray 10min, only the surface of a little carbon carbide burn does not wear fire does not smoke and gas. Of the phenolic foam composite board can be in addition to alkali corrosion, can withstand almost all of the inorganic acid, organic acids, organic solvents erosion. Long exposure to sunlight, no significant aging, which has a good resistance to aging.
From the model points: ① rigid waterproof casing points: A type, B type, C type, A type with steel pipe, B type for cast iron pipe and ductile iron pipe; ② flexible waterproof pipe points: A type, Type A is used in the interior wall of a building and type B is used in the facade of a building
Extruded polystyrene foam is divided into two kinds of expansive EPS and continuous extrusion XPS. Compared with EPS sheet, XPS board is the third generation of rigid foam insulation material, from the process it overcomes the complexity of EPS board Of the production process, with EPS board can not replace the superior performance. It is made of polystyrene resin and other additives through the extrusion process has a continuous uniform surface and closed-cell honeycomb structure of the plate, the honeycomb structure of the thick plate, there is no gap, this closed-cell structure Insulation materials can have different pressures (150-500Kpa) at the same time have the same low value of the thermal conductivity (only 0.028W / MK) and enduring excellent insulation and compression performance, compressive strength up to 220-500Kpa. XPS insulation board is extruded polystyrene insulation board, it is polystyrene resin as raw materials with other raw materials and aggregates, through a special process of heating and mixing at the same time into the catalyst, and then continuous extrusion (XPS),
