Keep warm
1. The extruded panel has the characteristics of high heat resistance, low linearity and low expansion ratio. The closed cell rate of the structure exceeds 99%, forming a vacuum layer to avoid air circulation and heat dissipation, ensuring the durability and stability of thermal insulation performance. 80% closed cell rate of foamed polyurethane, the advantages are self-evident.
Practice has proved that the thermal insulation effect of XPS extruded insulation board with a thickness of 20mm is equivalent to that of expanded polystyrene with a thickness of 50mm and cement perlite with a thickness of 120mm. Therefore, this material is a good choice for building insulation.
2. The fiber of rock wool composite board is slender and elastic, and the content of slag ball is low. Therefore, the thermal conductivity is low and the insulating effect is excellent.
Fire, damp, drowning
1. Drowning, moisture-proof
1) The water absorption rate of the extruded panel is an important parameter to measure the insulating material. After the water-absorbing material absorbs water, the thermal insulation performance is reduced. At low temperatures, ingested water tends to freeze, which destroys the structure of the insulation, reducing the compression and insulation properties of the panels. Since the molecular structure of polystyrene itself does not absorb water, the molecular structure of the panel is stable and free of gaps, which solves the problems of water leakage, penetration, frosting and condensation of other materials.
2) The submersion rate of rock wool composite slate water rock wool products can reach 99.9%; the water absorption rate is very low, and there is no capillary penetration. The volumetric moisture absorption rate of rock wool panel in a higher humidity environment is less than 0.2%, and it is tested according to ASTM C1104 or ASTM 1104M, and the mass moisture absorption rate is less than 0.3%.
The raw material of rock wool composite board is made of natural volcanic rock, which is a fireproof material for non-combustible building materials.
2. Main firefighting functions:
1) It has a high fire rating A1, which can effectively prevent the spread of fire.
2) Very dimensionally stable, will not stretch, shrink or deform in fire.
3) High temperature resistance, melting point higher than 1000°C.
4) No smoking or burning droplets/debris in fire.
5) No harmful substances or gases will be released in the event of fire.
Anticorrosion
1. The long-term use of the extruded sheet does not age, decompose, or harmful substances, its chemical properties are stable, it will not degrade due to water absorption and corrosion, its performance will decline, and it can still be maintained in a high temperature environment. XPS extruded insulation board has the performance, according to the relevant information, can maintain performance even after 30 to 40 years of use, and will not decompose or mold, and will not volatilize toxic substances.
2. Rock wool has stable chemical properties, PH value is 7-8, neutral or weakly alkaline, and has no corrosion to carbon steel, stainless steel, aluminum and other metal materials.
3. Due to the special structure of the extruded panel, its compressive strength is extremely high and its impact resistance is extremely strong. According to different models and thicknesses of XPS, its compressive strength reaches 150-500Kpa, which can withstand the ground load of various systems, so it has been widely used. Geothermal works, highways, airport runways, plaza floors, large cold storages and interior decoration and insulation.
4. The fully closed-cell foamed chemical structure of the extruded panel and its honeycomb-like physical structure make it lightweight, high-strength, easy to cut and transport, and not easy to break and easy to install. The extruded panel has been tested by the relevant state departments, and its chemical properties are stable, non-volatile, and harmful substances, which are harmless to the human body. The raw materials used are environmentally friendly materials and will not cause any industrial pollution. This product is an environmentally friendly building material.
5. Rock wool composite board is an ideal sound insulation material. A large number of slender fibers form a porous joint structure, which determines that the rock wool board is a sound-absorbing and noise-reducing material.
