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
Introduction to the properties of PVC skinned foam board Have you heard of PVC skinned foam board? I believe that many people will be very unfamiliar with the word PVC skinned foam board. Because if people are not engaged in related professions, they have no idea about PVC skinned foam board. Presumably you do not know the performance of PVC skinned foam board. Next, let me introduce the performa
PVC foam board is divided into PVC arch extruded foam board, PVC crust foam board and PVC free foam board; PVC crust foam board surface hardness is very high, it is difficult to produce scratches, widely used in cabinets, decoration, The surface hardness of PVC free-foamed boards such as buildings is average, which is mainly used for advertising. PVC foam board not only has all the advantages of w
It is a kind of PVC low foam board. It is produced by Celuka method. Taking PVC as the main raw material, combined with stabilizers, lubricants, foaming agents, fillers, cell regulators, impact modifiers, etc., in the forming stage, it has a large surface density, high hardness, and a small intermediate density through vacuum setting The cross-sectional structure of relatively low hardness, the su
How to improve the hardness of the core layer of PVC crust foaming board? The surface hardness of foam products is usually high, but the hardness of core layer, namely foam layer, is low. How to improve the hardness of core layer One is to add less plasticizer, the other is to reduce foaming ratio and bubble pore size Secondly, the appropriate amount of calcium powder and the supplementary use
Pearl cotton (cotton) is also called LDPE polyethylene, or EPE for short. In the production process of EPE high-foaming sheet, the physical foaming agent gas is first required to be in a gaseous state in the standard state, and it is easy to liquefy under the condition of pressurization through the special high-pressure metering pump. Because EPE resin foaming is the result of the physical foa
