Matters needing attention in the production process of PVC foam board During the extrusion process of PVC foam board, the problems encountered can basically be classified into 4 categories. One is the stability problem The second is the melt strength problem The third is the lubrication problem Four is the problem of dispersion These four types of problems, especially the first t
The equipment for PVC profiles is too familiar to me, and requires a production line for mixers, mills, crushers and extrusions. The U-groove processing equipment made for foreign customers this time is also very intentional. Now because of the epidemic situation, there is no way to go out for installation and commissioning. Remote guidance is required, and the equipment is sent to the customer af
What is SPC floor synchronization against flowers? What is the specific difference between the embossed and synchronized flower crafts in the SPC floor? Relief is a regular unevenness formed on the surface of the floor, but it is not synchronized with the wood grain. For example, the embossed steel plate like a wave is the same as the unevenness of the wood grain. Synchronous requirements for fl

1、 The advantages of plastic building formwork are as follows: 1. Smooth and smooth. The formwork splicing shall be tight and flat, and the surface degree and finish of the concrete structure after demoulding shall exceed the technical requirements of the existing fair faced formwork, so the secondary plastering is not required, and the work and materials shall be saved. 2. Light and easy to wea
1. What is SPC floor? SPC (stone plastic composite) stone plastic floor is a new type of environmental protection floor developed based on high technology. It has the characteristics of zero formaldehyde, mildew, moisture, fire, insect, and simple installation. SPC floor is extruder combined with T-shaped die to extrude PVC substrate, using three-roller or four-roller calender to separately app
SPC floor from zero to finished product, detailed process PVC floor composition PVC resin powder, stone powder, plasticizer, stabilizer, carbon black, the main components are polyvinyl chloride and stone powder. The plastic floor is composed of PVC substrate color film decorative paper, wear-resistant layer and UV drench coating in order from bottom to surface.
1. Five factors affecting quality In the extrusion process of PVC foam board, the problems encountered can be basically classified into five categories. One is stability problems; the other is melt strength problems; the third is lubrication problems; and the fourth is dispersion problems. These five types of problems, especially the first three types of problems, will be mutually restrictive a
