Long-term commitment to the R & D and manufacturing of extruded board insulation materials, a new service platform
Production workshop feeding volume per hour 2 tons, daily output 1000 cubic meters
High-pressure special extruded board is a special type of extruded polystyrene foam board (XPS). Through formula optimization and production process adjustment, the compressive strength of the material has been significantly improved and is suitable for applications with high requirements for bearing capacity. Scenes. The following is an introduction from aspects such as core characteristics, performance indicators, application scenarios, and differences from ordinary extruded boards
1. Core characteristics
High strength compression resistance
By increasing the polymer density and optimizing the cell structure (such as smaller cell size, more uniform distribution), the compressive strength is significantly higher than that of ordinary extruded sheets and can withstand higher loads.
The compressive strength of some products can reach more than 300kPa (ordinary extruded boards are usually 150-250kPa), and can be used as 1000kPa (such as used in extreme scenes such as airports and industrial floors).
High durability and stability
The closed pore ratio is as high as 99%, the water absorption rate is low (≤1.5%), and the moisture resistance is excellent. It is not easy to reduce the strength due to water absorption during long-term use.
It has strong aging resistance, stable performance under ultraviolet rays, temperature changes and other environments, and a service life of more than 25 years.
Dual advantages of insulation and compression resistance
Low thermal conductivity (≤0.030W/(m?) K)), which combines efficient insulation and high bearing capacity, meeting the dual needs of energy conservation and structure.
Construction convenience
The plate has moderate density (30-60kg/m3, adjusted according to the compression level) and can be cut and spliced to adapt to different construction scenarios.
2. Application scenarios
building floor works
Basement roof and garage floor: withstand vehicle loads and prevent ground subsidence.
Industrial factory floor: Suitable for long-term rolling of heavy equipment, forklifts, etc.
Floor heating system: High-compressive extruded panels (such as compressive strength ≥200kPa) can prevent the panels from being crushed by concrete filling layers, especially suitable for high-rise buildings.
road and bridge engineering
Expressway subgrade: Reduce subgrade settlement and improve pavement stability.
Bridge sound insulation layer, tunnel top: withstand the soil load and provide insulation effect.
Water conservancy and municipal engineering
River slope protection and dam foundation: resistant to pressure and moisture, preventing soil infiltration and causing structural damage.
Underground pipe backfill: protects the pipe from compression by upper loads.
Special load scenarios
Airport runways, logistics and warehousing ground: They need to withstand extreme loads such as aircraft take-off and landing and heavy machinery crushing.
Cold storage floor: Maintain strength in low temperature environment and prevent frost heaving damage.
3. The core difference between it and ordinary extruded board
comparative dimension High pressure extruded board Ordinary extruded board
compressive strength Significantly higher (300kPa+) Moderate (150-250kPa)
density Higher (35-60kg/m3) Lower (25-35kg/m3)
application scenarios Load-sensitive scenarios (such as ground, subgrade) Conventional wall and roof insulation
cost Higher (large raw material consumption, complex process) lower
4. Selection and construction key points
Selection suggestions
Select the compression level based on the actual load calculation requirements:
Residential floor heating, ordinary floor: compressive strength ≥200-300kPa.
Garage, industrial floor: compressive strength ≥400-600kPa.
Airport and heavy machinery areas: compressive strength ≥800-1000kPa.
Pay attention to combustion performance: Scenarios with high fire protection requirements need to choose Class B1 refractory type.
construction precautions
Base level: Ensure that the laying base is solid and flat to avoid local stress concentration.
Staggered joint splicing: The gap between the plates should be tight and fixed with tongue and groove splicing or adhesive to prevent displacement.
Protective layer construction: The surface must be covered with concrete, mortar or metal plates to avoid direct stress or exposure and aging.
V. Summary
Special extruded board for high compression resistance is a functional material that combines high strength bearing and efficient insulation. The core advantage is to meet the structural stability needs under high load scenarios. The selection must be combined with the load calculation, environmental conditions (such as humidity, temperature) and fire protection requirements of the specific project to ensure that the material properties match the design goals.
