Rolling process of PVC coiled floor

Rolling process, a production process of PVC coil floor.

In addition to the extrusion process, the PVC coil floor process also has a rolling process.

The rolling process is a rolling process of the base layer. Through the rolling of the base layer, the thickness of the produced product can reach the required thickness.

The base material production principles of the rolling process and the extrusion process are almost the same. First, the materials are mixed, then heated and plasticized, and finally the base material is extruded. The difference is that the rolling process is performed on the base material layer by layer. High temperature and high pressure bonding.

Then a tempering process is carried out, that is, the process of heating + water cooling. The purpose of this process is to increase the stability of the PVC coiled floor in the rolling process, and then carry out a high-temperature lamination of the printing layer and the wear-resistant layer. , followed by trimming and UV coating. After these processes are completed, it will be rolled into a large roll, and finally the quality inspection will be carried out. During the quality inspection process, it will be checked whether there are any defects, and the large roll will be PVC floor rolls are cut into small rolls of PVC floor rolls.

The position of the glass fiber layer of the extrusion process and the rolling process is also different. The glass fiber layer of the extrusion process is added when the surface material is made, while the glass fiber layer of the rolling process is located in the middle of the two base layers. .

The process of the rolling process is not simple, the equipment required is relatively more, the energy consumption is also more, and the labor demand is also more, so the cost of using this process will be high, but due to the extrusion The resulting base layer is thinner, so the stirring will be more sufficient, so from the perspective of stability, it will be more stable, and there will be more adequate quality inspection, the occurrence of defects will be greatly reduced, or even no, Also, because the defective parts will be cut out, the packaging is generally divided into standard rolls and non-standard rolls. The standard roll has a fixed size, while the size of the non-standard roll is not unique.
