How To Solve The Problem Of Poor Plasticization Of Granulator?
The manifestations of poor plasticization of twin-screw extruder equipment are:
In the process of regular use and control of plastic extruders, everyone will encounter certain problems that will cause poor plasticization. So what is the cause of poor plasticization? And how to completely solve this problem? ?Okay, everyone is getting to the point. I hope my article can help everyone. I will list the specific situations and solutions below for everyone to refer to.
The manifestations of poor plasticization of twin-screw extruder equipment are:
There are toad skin-like problems on the outer surface of the plastic; the temperature control, the actual measured temperature is low, and the temperature indicated by the indicator needle on the instrument panel is low; the plastic surface is blackened with tiny cracks and small particles that are not plasticized well; the plastic glue seams are not good OK, there will be a noticeable mark.
Common factors causing poor plasticization of twin-screw extruder equipment:
The temperature control is too low or the operation is inappropriate;
Plastics contain resin particles that are difficult to plasticize;
Improper operation method, the screw and traction speed are too fast, and the plastic is not fully plasticized;
When the twin-screw extruder equipment is used for plastic granulation, the plastic is mixed unevenly or the plastic itself has quality issues.
Applicable solutions to common faults caused by poor plasticization of twin-screw extruder equipment:
Control the heat according to the requirements of the processing technology. If you find that the temperature is low, increase the heat appropriately;
The speed of the screw and traction should be appropriately reduced to increase the heating and plasticizing time of the plastic to improve the actual effect of plastic plasticizing;
Make full use of the screw cooling circulating water to enhance the plasticization and tightness of the plastic;
When selecting a mold, make the mold sleeve appropriately smaller to increase the pressure on the glue outlet.
The above is the editor's introduction. I hope it will be helpful to everyone in understanding the twin-screw extruder equipment. If you want to know more information, please pay attention to the news on this website.
