PVC pipe production line is a complete set of equipment that processes PVC raw materials into pipes through continuous extrusion molding. The core is to realize the automated process of raw material melting, molding, shaping and cutting. Its stability directly determines the dimensional accuracy and physical properties of the pipes.
To reduce WPC granulator screw breakage, it is recommended to control the source: prioritize bimetallic thread blocks with strict heat treatment during purchase; ensure uniform feeding and regular cleaning of foreign matter in raw materials during use; inspect thread block wear and assembly clearance every 100-200 hours of operation.
Extruder gearbox is the "power transmission core" of extrusion equipment, its failure will directly lead to production interruption or abnormal product quality.
Although coupling agent is a small component, it is the invisible force that transforms wood-plastic products from "qualified" to "high-quality"—it not only solves immediate production challenges but also comprehensively upgrades product quality, lifespan, and cost.
A:PET's high-temperature sensitivity, poor interfacial compatibility, high melt viscosity, and hydrolysis resistance limitations present significant technical bottlenecks for its application in the WPC industry. Therefore, under current technological conditions, PET is not suitable for the production of WPC products.
In the production of wood-plastic WPC decking, plastic is one of the important raw materials, which needs to be combined with wood fiber and other materials, and needs to have good compatibility, processing and weather resistance. The following are some of the most commonly used plastic types: PE, PP, PVC
