Production process of porous plastic tube
Crush and dry the raw materials such as PVC, PE or PP, control the moisture ≤ 0.5% to ensure the purity of the material.
Through the three-screw extruder heated to 220-250 ℃, pressure 10-20 MPa, through the die extrusion molding. The mold design determines the porosity (25%-30%) and wall thickness uniformity.
Adopt 20-30℃ water tank for rapid cooling to avoid deformation and ensure dimensional stability.
Precision cutting to standard length (6-8 meters), compression test, appearance inspection and size measurement.
Packed with moisture-proof and environmentally friendly materials, suitable for long-distance transportation.
Advantages of porous plastic tube
The honeycomb/grid structure makes the compressive performance 10-100 times higher than ordinary plastic pipes, which can replace steel pipes crossing the road.
The integrated design of sheath and sub-pipe eliminates the need for secondary threading and saves 30% of the construction period; the bending radius is up to 4 meters, which is suitable for complex terrain.
The material can be recycled and the production energy consumption is low; the comprehensive cost is 20% lower than PE pipe and 50% lower than steel pipe.
Resistant to acid and alkali, aging, service life ≥50 years, suitable for coastal and chemical environments.
Application of porous plastic tube
| Fields | Specific Scenarios |
|---|---|
| Communication Engineering | Fiber optic cable/cable casing, weak power pipe network (e.g. 24-hole trunk pipeline in Laoshan District, Qingdao City) |
| Municipal Construction | Drainage Systems, Comprehensive Underground Pipe Corridors (Excavation is only 10% of a concrete pipe) |
| Agricultural Irrigation | Water-saving seepage irrigation system, reduce water waste |
| Electric Power Engineering | High-voltage cable protection, excellent insulation performance |
| Construction | Underfloor Heating Pipes, Rainwater Harvesting Systems, Replacement of Concrete Pipes |
Porous plastic pipes have become the preferred material for modern infrastructure construction due to their modular design, cost-effectiveness and environmental friendliness. In the future, with the application of nano-coating technology and bio-based materials, its performance and market penetration will be further enhanced.
