Product Description

Production Process Display

1. Raw Material Pretreatment: PVC resin, alkali-resistant agents, stabilizers and other raw materials are put into the mixer in proportion, and stirred at high speed to 80-90℃ to ensure uniform mixing of raw materials and improve the alkali resistance of pipes.

2. Extrusion Molding: The mixed raw materials are sent to the twin-screw extruder, melted and plasticized at high temperature, and then extruded into pipe blanks through a special mold.

3. Sizing and Cooling: The pipes enter the vacuum sizing box, and through negative pressure adsorption and spray cooling, the pipe diameter and shape are quickly fixed to ensure the roundness and dimensional accuracy of the pipes.

4. Traction and Cutting: The sized pipes are pulled at a constant speed by the tractor, and then accurately cut to the set length by the automatic cutting saw.

5. Finished Product Stacking: The cut finished products are automatically stacked by the stacking machine, facilitating subsequent inspection, packaging and delivery.

Core Advantages

1. Super Alkali Resistance for Special Scenarios

The production line adopts customized formulas and special extrusion molds. The hard PVC pipes produced have passed strict alkali resistance tests, and can be directly used in special scenarios such as alkaline wastewater discharge in chemical enterprises and strong alkali environment drainage in municipal sewage treatment plants, solving the pain points of ordinary PVC pipes being prone to corrosion and having a short service life.

2. Fully Automated Production for Doubled Efficiency

The complete production line includes raw material mixing system, twin-screw extruder, vacuum sizing device, tractor, automatic cutting saw, stacking machine and other equipment. The whole process from raw material input to finished product output is automated. The hourly output of a single production line can save 30% of labor costs compared with semi-automatic production lines, and the production stability error is controlled within ±0.5mm.

3. Multi-Functional Adaptation to Meet Diverse Needs

It supports the production of drainage pipes with different calibers, and can quickly switch product specifications by replacing molds. At the same time, it is compatible with two production modes: ordinary drainage and alkali-resistant drainage. Enterprises do not need to purchase additional equipment, and can flexibly respond to different customer orders, improving equipment utilization.

4. Energy Conservation, Consumption Reduction and Green Production

The extruder adopts a variable-frequency motor and high-efficiency heating coil, reducing energy consumption by 15% compared with traditional equipment. The raw material mixing system is equipped with a dust recovery device, which reduces raw material waste and environmental pollution, complies with national environmental protection production standards, and helps enterprises build a green factory image.

Application Scenarios

1、Municipal Engineering: Urban sewage treatment plants, rainwater drainage pipe networks (especially suitable for alkaline sewage areas around chemical enterprises);

2、Chemical Industrial Parks: Production wastewater (containing alkali components) discharge pipes and circulating water transmission pipes in chemical enterprises;

3、Construction Industry: Indoor and outdoor drainage pipes in industrial plants, laboratories and other places, resisting corrosion from alkaline cleaning solutions;

4、Agricultural Field: Irrigation and drainage pipes in saline-alkali land, and alkaline wastewater discharge pipes in breeding farms.
