Extrusion board specifications and uses
Extruded plastic panels are mainly used in cold storage refrigerated trucks, central air-conditioning ventilation ducts, steel structure roofs, building wall insulation, building roof insulation, floor heating and other fields. The extruded board has the characteristics of good stability and anti-corrosion performance, thermal insulation, high strength and compression resistance, moisture resistance and environmental protection, and has irreplaceable advantages.
Extrusion board has good thermal insulation function:
Because of its closed-cell structure, the extruded board has a good thermal insulation function. Although foamed polyurethane has a closed-cell construction, its closed-cell ratio is smaller than that of extruded board. The extruded board is superior to other thermal insulation materials in terms of thermal insulation function, water absorption function or compressive strength, so it is also unmatched by other thermal insulation materials in terms of thermal insulation function.
Extruded board has unexpected compressive strength:
The compressive strength of the extruded board can reach 150-700 kPa or more according to the thickness of its different models, while the compressive strength of other materials is only 150-300 kPa or more.
The extruded board has a strong water absorption function:
Used under the road surface and roadbed, the waterproof penetration effect is very obvious. Especially in the north, it can reduce the occurrence of frost and frost-affected soil freezing, and effectively isolate the ground from moisture damage.
The extruded board adopts the double-drive pair-roller kneading technology, from feeding, mixing, extrusion, pulling, cutting, etc., in one go, the produced extruded board has a uniform thickness, less labor, 4-6 people.
The extruded board is a board with a continuous and uniform surface layer and a closed-cell honeycomb structure produced by polystyrene resin and other additives through the extrusion process. These thick boards of honeycomb structure. There will be no voids at all. This closed-cell structure thermal insulation material can have different pressures (150-500Kpa) and has the same low thermal conductivity (only 0.028W/M.K) and long-lasting excellent thermal insulation and resistance. Compressive properties, the compressive strength can reach 220-500Kpa.
