Ps plastic can be made into xps and eps board , both of which are used on the exterior wall of buildings as thermal insulation materials, which are environmentally friendly and energy saving. Therefore, from many years ago, the two materials xps extruded board and eps polymer benzene The board is widely used. Xps extrusion Insulation board It belongs to the third generation of hard foam thermal insulation material. Compared with EPS polystyrene board, its process is much simpler, and it has superior performance that EPS polystyrene board cannot replace. XPS extruded board is a board made of resin, Freon, hexabromo flame retardant and other components through foaming extrusion in the machine. This board is composed of continuous and uniform bubbles, like honeycomb closed cell structure, without any gaps. It can not only isolate the air transmission, achieve temperature retention, and the thermal conductivity is only 0.028w/m.k, but also can isolate the transmission of water vapor, so as to achieve waterproof and moisture-proof. Xps extruded plates can have different compressive strength, between 220-500kpa, due to different specifications, Shandong Grade B1 extruded board, good heat preservation, moisture resistance and compression resistance.
The performance characteristics of the olefin extruded board are described in detail below:

1. Thermal insulation of
Due to the natural structural characteristics of the extruded board, its closed porosity has reached Above 99%, a vacuum layer is formed to isolate the air flow and avoid heat dissipation. In summer, outdoor heat waves enter the room, and in winter, indoor heat is emitted to the outside, saving energy and reducing pollution. Extruded boards used in buildings will be sealed wall It can isolate the air and avoid oxidation, and its service life is up to 40 years. It can be said that it is a comprehensive thermal insulation material used for external walls at present. After experimental comparison, it is found that the thermal insulation of 20mm thick xps extruded insulation board is equivalent to that of 50mm thick foam insulation board, that is, polystyrene board, or 120mm thick cement Perlite, while polystyrene board is much lighter in weight and easy to construct.
2. Superior compression resistance
because Xps flame retardant extruded board Vacuum closed cell structure, so its compressive strength is very high, and its impact resistance is relatively good. According to Xps flame-retardant extruded plate has different models, thicknesses, unit weights and other specifications. Its compressive strength is more than 220-500kpa, and can withstand various ground loads. It is used in geothermal floor heating plates, highways, airport runways, square floors, and large refrigerators and other fields.

3. Excellent hydrophobic, waterproof and moisture-proof performance
Water absorption is very important for insulation boards. If you inhale too much water, first of all, the effectiveness of insulation will be greatly reduced. In addition, insulation boards are attached to the exterior wall. If the insulation board absorbs too much water over a long period of time, it will fall off the wall under its own weight. In addition, Shandong extruded boards are usually used in colder areas. If its water absorption is too high, it will freeze and freeze in winter, Then the structure of the wall insulation board is damaged, and it has to be rebuilt due to aging and falling off. This is the unqualified building facilities, which need to be rebuilt. However, the extruded board itself is made of extruded board, and the plastic itself will not absorb water. With its closed cell structure, water vapor can not enter the interior at all, and will not absorb water. As long as the board does not split, it will be OK. Compared with other thermal insulation materials, it is inevitable that there are problems such as water absorption, leakage, infiltration, frosting, etc. Therefore, on the one hand, we use extruded boards for thermal insulation, on the other hand, we use them more for waterproof and moisture-proof, such as foundation protection, roof extruded boards, etc.
4. Light texture, easy to use
The foam structure of the Xps flame-retardant extruded board is similar to the honeycomb physical structure. The vacuum hole is not only light, but also has high strength. It is convenient to cut, transport, do not damage, and install. It is also convenient to use thicker construction.

5. Stable performance, good corrosion resistance
As long as the B1 fire-retardant extruded board is not exposed to the air and sunlight for a long time, its performance will be stable. From the manufacturer of the extruded board to the construction site, it will be sealed in the wall. It can be used for 30-40 years without sunlight or air. This is something that almost more than 80% of thermal insulation materials cannot achieve. With flame retardant B1 and B2 extruded boards In the high temperature combustion environment, it can still maintain its superior performance. It is non combustible, non combustible, non decomposable, non moldy, and free from the volatilization of toxic substances. It is safe and easy to use. It is used by the extrusion board manufacturer.
6. Environmental protection and energy conservation
Another way to save energy is to protect the environment. For example, when heating is used in winter, the indoor temperature reaches 26 degrees, no Xps exterior wall insulation board In case of continuous heating As soon as we enter winter, the national haze is not easy to dissipate, but in the cold winter air, the vast majority of people still feel that the warmth is real. If our wall uses external wall insulation board and roof insulation board, it will improve the indoor problem If the temperature is 3-5 ℃, the heating can reduce the heat supply by 3-5 ℃, reduce smoke emissions, reduce haze, achieve environmental protection, and keep the sky blue in winter. Another example is that in summer, the outdoor heat wave continuously impacts the wall, which will make us unable to turn on the air conditioner, and the air conditioner consumes electricity. If we use xps exterior wall extruded panels to isolate the heat and reduce the indoor temperature by 3-5 degrees, we can reduce the waste of electricity, and make the house equipped with b1 and b2 extruded panels warm in winter and cool in summer, comfortable, energy-saving and environmentally friendly.
Applicable scope of extruded board
Xps extruded boards are used in various fields of our lives. The roof insulation and waterproofing of buildings, the roof of steel structures, the wall insulation of buildings' external walls, the ground waterproofing and moisture-proof of buildings, the ground waterproofing of squares, the ground anti frost heave and collapse prevention, the thermal insulation layer of airport runways, the subgrade of expressways, and the construction of refrigerators are inseparable from extruded boards, In addition, thick extruded boards should be used to keep warm, waterproof and damp proof.
