Process temperature control of PVC pipe

Process temperature control of PVC pipe
To accurately control the extrusion temperature, we must first understand the processed materials the relationship between temperature limit and physical performance, find out its characteristics and rules, to choose a better temperature scale extrusion molding. So in the temperature setting should consider their properties of polymer, the performance of the equipment and the observation tube die extrusion billet surface is not lubrication, no bubble phenomenon to distinguish. The extrusion temperature includes the setting temperature and the melt temperature of the heater. Heating temperature is the temperature that is supplied by the external heater. Melt temperature is the temperature of the material between the front and the head of the screw.
There is a barrel temperature distribution from the feed zone to the die may be flat spread, increasing spread, decreasing dispersion and mixed distribution, basically depend on the material and structure of extruder.
