What Is The Different Between A Single-layer Film Blower And Double-layer Film Blower

For those who often use the film blower, I believe that it is no stranger to the film blower, but one thing is a problem that the operator of the film blower hates is, that is, how much temperature range is controlled by the film blower to blow the plastic film to control the plastic film to control the temperature range of the plastic film. It is appropriate that because the temperature may directly or indirectly cause the quality of the film blower to blow the plastic film, the temperature of the film blower must be controlled.
At the beginning of the melting section, the temperature reaches the sticky temperature before it can melt. For crystal resin, the sticky temperature is equal to the melting point temperature. Then constantly compress and increase the melting layer, the temperature needs to be continuously increased to make the resin molecular chain range from the length. The high molecules of different thermal exercise energy have melted. Therefore Other parts are warmed up.
At the entrance of the feeding section, the temperature is lower, and the resin sticky is to prevent the resin from blocking into the material. In addition, the resin in the adding section will continue to compress, and the air will be discharged from the ingredients upside down. Depending on the device structure, although the feeding mouth does not perform electric heating, it is passed through the heating of the machine, and the temperature of the feeding section is determined. The entrance is 50-90 degrees, and the end is equal to the melting point or sticky temperature, which can be fixed as a temperature such as temperature such as temperature.
The main point for the control of the squeeze temperature of the membrane machine is:
Different species of resin, the temperature of the film blowing film process temperature is different;
The same type of resin, different models and melting indexes. The temperature of the film blowing is different, the index is large, and the temperature is low.
The same type of resin, different thickness film, and the process temperature of the process. The processing thick film with a thick film can be higher, and the temperature of the membrane mouth can also be higher, which is conducive to reducing viscosity and increasing productivity.
How to control the temperature of the film blower, I will introduce so much, I hope to help you!
