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
I. Overview 1. Definition of WPC; Wood-plastic composite materials are mainly composed of sawdust, wood chips, bamboo chips, straw, wheat oranges, bran, peanut shells, bagasse, coconut shells, and hemp. A new type of environmentally friendly materials. English name of wood plastic: Wood-plastic Composites, abbreviated WPC
Rigid PVC crust foam board is made of polyvinyl chloride (PVC) as the main raw material through a special foaming process. It is one of the typical new chemical building materials products that replace wood with plastic. Due to its fine internal density of cell structure, the surface is similar to natural wood. The furniture, kitchen and toilet materials, decoration and decoration industries have
How to distinguish the true and false skinning building materials of PVC skinning foam board With its unique performance and beautiful appearance, PVC skinning board is widely used in major industries. I believe many customers are more interested in how to distinguish its true and false. PVC crust foam board has excellent corrosion resistance, insulation, and has a certain mechanical stren
Application of PVC foam board in cabinet A cabinet refers to a platform for storing kitchenware and cooking operations in the kitchen. The key to a solid, environmentally friendly, "longevity" cabinet is the cabinet. What kind of cabinet is good? Let's take a look. Cabinets, also known as cabinet panels and cabinet panels, act like skeletons of human bodies in cabinets. The material and struc
