HOW MUCH you know SPC lock floor SPC lock floor consists of thickened wear-resistant layer, UV layer, color film texture layer and base material layer. European and American countries call this kind of floor RVP (rigid vinyl plank), rigid plastic floor. The base material is a composite plate made of stone powder and thermoplastic polymer material, which is evenly stirred and then extruded at high
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
The reasons and solutions of the foam breaking of PVC foam board The application of PVC foam board is relatively important in the current use, which is mainly because the product's use effect is very good. However, there are good and bad use of the product. For example, the foaming of the PVC foam board is a condition that affects the quality of the product. If you don’t pay attention, it will
What are the extrusion problems of PVC foam board? What are the extrusion problems of PVC foam board? This is the related question we are going to talk about in this issue. The answer to this question is in the following elaboration: PVC board 1. If the stability is not enough, the whole board surface will be affected. The board surface will turn yellow and the foam sheet will be brittle. 2. L
What are the key points of control in the production of PVC skinning and foaming board? It is necessary to make the blisters of PVC skinned foam board dense and evenly distributed. In addition, there is a hard and dense surface layer, which is the key to be controlled in the production process: 1. The extruder and die can provide continuous high pressure to make the foaming agent dissolve in the
Analysis and Countermeasures of Typical Causes of Foam Breaking of PVC Crust Foam Board There are two main factors in the foaming or foaming of the foamed plastic plate section in theory: one is that the local strength of the melt itself is too low, and the foaming is formed from outside to inside; second, the pressure around the melt is biased Small, swollen local cells, weakened in strength,
Solve the common problems in PVC foam board extrusion In the extrusion process of PVC foamed sheet, the problems encountered can be classified into four categories: stability, melt strength, lubrication and dispersion. These four kinds of problems, especially the first three, will restrict and cross influence each other. From the surface phenomenon, sometimes the stability is not enough, which wi
