What is the PVC coil floor extrusion process?
The PVC coil floor process is by no means the only one, and the extrusion process is one of the PVC coil floor processes.
The inherent explanation for the extrusion process means that the material passes through the action between the extruder barrel and the screw, while being heated and plasticized, it is pushed forward by the screw, and continuously passes through the head to make various cross-section products or semi-products. a processing method. The extrusion process in PVC coils has a relatively fixed production process.
The production process can be divided into two types: fabric production and substrate production.
The three steps of fabric production are: printing color film, high-temperature lamination of glass fiber layer and high-temperature lamination of wear-resistant layer, without adding glue in the middle, through high temperature High-pressure lamination; and the production of the substrate is also three steps: mixing, heating and plasticizing, and extrusion molding. During the heating and plasticizing process, it is stirred according to a certain formula. In addition, the plasticizing process may be one time. It is also possible to mix the various ingredients evenly in multiple passes.

Then, the fabric production and the semi-finished product produced from the base material are bonded at high temperature. The next step is to trim the edges according to the standard. The effect of protection, and the final quality inspection, mainly check the appearance, quantity, etc. of the product, and then carry out packaging. In the process of rolling, Keen.
Advantages of extrusion process: The process flow is relatively simple to a certain extent, and the degree of automation is high, using less machinery and equipment, less energy consumption, less labor, and low cost.
The extrusion process also has disadvantages: because in the process of stirring the material to a fixed thickness, there may be insufficient stirring evenly, and due to the influence of air during the extrusion process, bubbles may appear, so thickness and density may appear. Inconsistency will affect the stability of the product to a certain extent, so the stability of the product may have some deviations relatively.
