How many of you know the advantages of plastic film blowing machine?
Film blowing machine should pay attention to the following matters during operation: in the raw material when opening a bag to check the wet material, wet material may stir the material, must be approved by the chamber after drying, can be used. Equipment without heating, heating temperature and time is not required, shall not start the extruder and the rotating die, otherwise it will damage the equipment. Die and die cleaning can only be used to clear the copper die, not with the shovel, iron scraping die, otherwise it will cause damage to the die. Corona treatment guide roller must not be opened without a film about corona processor once film cutting or shutdown, turn off emergency corona processor corona processor to avoid burn out.
Density polyethylene (LDPE) is a kind of plastic material, which is suitable for thermoplastic forming process, and the forming process is good. LDPE is mainly used for film products, also used in injection molding products, medical equipment, medicine and food packaging materials, blow molding hollow products, etc.. Linear low density polyethylene, the structure is different from the general low density polyethylene, because there is no long chain.
The linearity of LLDPE depends on the different production processes of LLDPE and LDPE. LLDPE usually in lower temperature and pressure, by the ethylene and advanced a olefins such as the polymerization of maleic or. The LLDPE polymer produced by the copolymerization process has a narrower molecular weight distribution than that of the general LDPE, and has a linear structure with different rheological properties.
The quality of Dalian film blowing machine quality and blowing technology determines the film forming. So the film blowing machine a good performance in the process of producing films showed good ability to adapt to the market, improving production efficiency, provide convenience for the people, and promote the harmonious development of society. Food packaging is the most widely used field of film blowing machine, blown film can be used as high-grade packaging propaganda, improve the business value.
