Introduction: life, we can come into contact with a variety of plastic pipe, large to some transportation pipeline, small to drink straws, almost all over our daily life, can be said to be closely related to our survival. So these pipe products and how to produce it? Here we will learn about the plastic pipe production process knowledge.
Common Plastic Pipe
Our daily life in the common plastic pipe is mainly PVC pipe. PVC (Polyvinyl?chloride) polychlorinated ethylene, it is by the vinyl chloride monomer in certain conditions after the polymerization reaction polymer. In this PVC material to add a variety of additives, auxiliary materials can be obtained to have a particular performance of the material, so as to make a certain commodity and used in a certain field. We live in all kinds of pipes, most of which are made of PVC materials as raw materials, after a certain production molding process, made of plastic pipes can be applied to the actual life of different sizes and functions. In order to improve the strength of the pipe, impact resistance, corrosion resistance, as well as to meet the special requirements of some special applications, will add a variety of corresponding additives in the production process, such as lubricants, impact agents, stabilizers, etc., so as to obtain the UPVC pipe, CPVC pipe and other better performance of the pipe.
Types of plastic pipe
In addition to the PVC material as raw material for the pipe, there are polyethylene (PE) pipe, polybutylene (PB) pipe, engineering plastics (ABS) pipe and other plastic pipe, of course, with the continuous development and progress of science and technology, more and more plastic pipe. The continuous development and progress of science and technology, more and more excellent performance, good quality and low-cost pipe will be developed to adapt to the needs of society, to meet people's needs.
Plastic pipe production process
Pipe extrusion molding needs to be carried out in the extruder, PVC pipe molding can be used both twin-screw extruder can also be used for single-screw extruder.
The following PVC PVC PVC as raw materials and pipe molding on the twin-screw extruder as an example, a brief description of the production process of pipe.
One, the production of the corresponding performance of the size of the pipe before the need to calculate the required raw materials, weighing and formulation.
Two, the raw materials have been formulated in the relevant equipment for high-speed thermal mixing.
Third, after the raw materials are mixed evenly, under the action of the cooling system, the raw materials are cooled down and in a molten state.
Fourth, the molten state of the raw material by the extruder after the formation of the billet, the billet is cooled down to make the shape of the billet to obtain a better surface quality.
Fifth, through the traction machine, cutting machine and other equipment for the molded tube traction, cutting, flaring and other subsequent processes to meet the specific shape and size requirements.
Sixth, the final comprehensive quality inspection, and qualified products will be packed into the warehouse.
For the pipe production process of knowledge is introduced to this, of course, in the actual production, the production of pipe but also pay attention to many aspects of the problem, and not just a few words can be summarized. With the rapid progress of science and technology, more and more and better products will be presented in front of us, to our ordinary life bring extraordinary experience.
