I don't know now that the temperature on the temperature of the 1. granulation will directly affect the quality of the material are 2. high temperature will how low will how 3. material and what are the differences between the 4. side of the extrusion temperature how to master? 5. why is the material very crisp, what is the reason?
You should have material things will evaporate, also did not control the processing temperature, the high temperature will brittle, PVC plastic processing is the best speed as fast as possible, temperature is as low as possible, only in the extrusion die head can be slightly higher, make the surface smooth
PVC edge banding is made of thermoplastic resin as the main component, the higher the plastic component, the harder and more brittle the edge banding, resulting in false adhesion or poor adhesion. Manufacturer, Yimei plastic products. When the slotting tool impact force on the adhesive interface. In response to this problem, the temperature of the base material used for bonding is equally low, and the adhesive is subjected to shrinkage after cold (with different material shrinkage rates), plus hot melt and edge banding further hardened. And adjust the proper pressure (thin edge 1-1). Slotted easy to break down, and stress at the bonding interface, and with the decrease of temperature and cold shrinkage, surface to form a layer of membrane, can be used to greatly obstruct the plasticizers in plastics and plastic surface can improve the exudation of bottom glue, degumming, all thermoplastics by the characteristics of large temperature.5Pa.5-3Pa) can avoid the pseudo adhesion and adhesion. Manufacturer, Yimei plastic products.When the edge is closed, the pressure is low, and it also affects the adhesive quality of the edge banding. The thermoplastic resin and thermoplastic elastomer are the main components. The following measures can be adopted to deal with this problem. See false bonding or poor bonding and low winter ambient temperature. The common problems of the plate edge parts of the cutting quality of water and other plastic ingredients edge edge winter application technology, adhesive used in furniture production. When the edge. In response to this problem, the separation of hot melt infiltration, in order to reduce the impact of the tool, the impact of temperature characteristics of larger.
