2. Main raw materials and formula design of PVC plumbing pipes
main ingreadient
PVC resin: As the main material of the pipe, the choice of PVC resin directly affects the physical properties and service life of the pipe.
Stabilizer: used to improve the thermal stability and weather resistance of PVC resin to ensure the stability of pipes in different environments.
Lubricant: Reduce the viscosity of PVC resin, improve processing performance, and make the pipe easier to form.
Fillers: Increase the strength and hardness of pipes while reducing costs.
Formulation design
When designing the formula, it is necessary to fully consider factors such as the source and cost of raw materials, the usage occasions of the pipe, and environmental conditions. Through scientific formula design, we can ensure that the performance of the pipe meets the usage requirements while reducing production costs.
3. Manufacturing process of PVC plumbing pipes
Raw material preparation
According to the formula proportion, raw materials such as PVC resin, stabilizer, lubricant and filler are accurately measured, and then mixed and pulverized to ensure the uniformity and particle size of the raw materials.
Mix
The crushed raw materials are fed into the mixer and stirred at high speed to fully mix the various raw materials evenly. Through mixing, the plasticity and processing performance of PVC resin can be improved.
Extrusion molding
The mixed raw materials are fed into the extruder, and through the rotation and heating of the screw, the raw materials are heated and pushed to the mold. Under the action of high temperature and high pressure, the raw materials are extruded into a pipe shape.
Cooling and shaping
The extruded pipe is quickly cooled through a cooling table to solidify and shape it. During the cooling process, the cooling can be accelerated by adjusting the water injection speed and pressure and using coolant.
Cutting and Trimming
Cut the cooled and shaped pipe to the required length. Then use an edge trimmer to trim both ends of the pipe to ensure the accuracy and smoothness of the pipe diameter.
Quality Inspection
Conduct quality inspection on the produced PVC plumbing pipes, including appearance quality, dimensional accuracy, processing performance and mechanical properties. Ensure that the quality of pipes meets relevant standards and requirements.
4. Conclusion
The manufacturing process of PVC plumbing pipes is a complex and delicate process that requires scientific formula design and strict process control. By continuously optimizing manufacturing processes and improving product quality, we can meet the needs of different fields and promote the sustainable development of the industry.
