1. The equipment is not heated, and the heating temperature and time are less than the specified requirements. Do not start the extruder and the rotary die, otherwise the equipment will be damaged.
2. When the raw materials are unpacked, check whether there is wet material. Wet material must not be mixed. It can only be used after drying in the drying room.
3. When cleaning the die head and die port, only copper sheet can be used to clean the die port. Do not scrape the die port with a shovel or iron sheet, otherwise the die port will be damaged.
4. The guide rollers of plastic film blowing machines, including rubber rollers and rewinding rollers, must not be cut with a blade, otherwise the guide rollers will be scratched.
5. The filter screen and corona processor of the extruder need to be regularly replaced for filtering and cleaning. Generally, the filter screen and the silicone roller of the corona processor need to be replaced within 24 hours to 48 hours. Filter specifications: two layers of 80 mesh, one layer of 100 mesh three layers of filters.
6. The guide roller of the corona processor should not be turned on without the film walking. Once the film is cut or stopped, the corona processor should be shut down urgently to prevent the corona processor from burning out.
7. Films without corona treatment or corona treatment not exceeding 38 dyne should not be put into the finished product, otherwise it will cause a major accident of composite quality.
