Ống PVC trở thành xương sống của hệ thống thoát nước như thế nào
Hệ thống thoát nước bằng ống PVC đóng vai trò là hệ thống thoát nước của thành phố “tĩnh mạch ngầm”, xử lý xả nước mưa, nước thải sinh hoạt, và nước thải công nghiệp. Ống PVC, được ưa chuộng trên toàn cầu cho hệ thống thoát nước, offer excellent performance and arise from a mature automated manufacturing process.

1. The Core Advantages of PVC Pipes in Drainage Systems
Drainage pipes must handle sewage exposure, resist chemicals, withstand soil or negative pressure, have smooth inner walls, and last for decades.
Smooth inner walls outperform cast iron and concrete pipes. The low Manning coefficient boosts drainage and reduces energy costs.
PVC resists acid, alkali, salt, and microbes. No extra anti-corrosion coating is needed, suiting complex water environments.
PVC pipes are lightweight, at just 1/5 the density of steel. Cutting and connecting is easy, speeding construction and reducing costs.
PVC pipes have a lower lifecycle cost and are reliable. They are the top choice in municipal, building, and agricultural drainage.
2. Ống PVC Quy trình sản xuất

1. Raw Material Preparation and Mixing
PVC-U resin forms the base. Add heat stabilizers, lubricants, fillers, and aids as per standards. Mixing ensures uniformity at 80–120°C, supporting plasticization.
2. Twin-Screw Extrusion and Plasticization Homogenization
The compound enters a twin-screw extruder. Shear heat and external heating at 160–200°C melt, degas, and homogenize material, forming a dense PVC melt. Screw settings and temperature zones are key to pipe quality.
3. Vacuum Shaping and Gradient Cooling
After extrusion, the melt goes to a vacuum sizing tank. Vacuum and cooling keep the pipe round and even. Wrong cooling rates cause warping or brittleness.
4. Traction, Cắt, and Online Inspection
A traction machine pulls the pipe to match the extrusion and cooling speed. Automatic cutters standardize lengths. Laser measurement, wall thickness scans, and visual inspection give fast quality feedback.
3. Green Intelligent Manufacturing and Industry Evolution Trends
Tighter environmental rules and ‘dual carbon’ goals drive industry change.
· Non-toxic formula: Gradually phase out lead salt stabilizers and fully switch to calcium-zinc compound stabilizers and organic tin environmental protection systems.
Recycling technology for PVC pipes is mature. Recycled PVC serves non-pressure pipes, reducing the carbon footprint.
IoT, AI inspection, and digital twin models optimize energy, improve yield, and enable predictive maintenance on production lines.
Nano-modification and co-extrusion foaming lower weight and reduce noise while keeping strength. These suit new uses like sponge cities and prefabricated buildings.
