The use of plastic blown film machine is problems should pay attention to safety

Low density polyethylene degrees polyethylene (LDPE) is a kind of plastic material, it is suitable for thermoplastic processing a variety of molding process, forming good workability. LDPE main purpose is for thin film product, also used in plastic injection products, medical devices, pharmaceutical and food packaging materials, hollow blow molding products, etc.

Linear low density polyethylene, structurally different from general of low density polyethylene, because there is no long branches chain. LLDPE linearity depends on the different production process of LLDPE and LDPE. LLDPE under lower temperature and pressure, usually by a olefins such as ethylene and senior butene, hexene or octene copolymerization and generated. Copolymerization process of LLDPE polymers with narrow molecular weight distribution, better than the average LDPE with linear structure at the same time make its have different rheological properties. Host after open, pay close attention to the host running situation and timely adjust, amend, electric meter, controller, observe whether there are abnormal or damaged, replacement and maintenance, to ensure its normal operation. Host gear box, traction reducer should often come on, change gear oil (oil level to achieve scale line) and new in the use of 10 days or so, please change new gear oil, in order to ensure the normal operation of the rotating parts, to prevent overheating and damage of the difficulty of working, but should also check the connection parts of tight situation, to prevent the bolt is loose. Bubble tube of the compressed air should be kept in balance, in the process of traction, compressed air leak out, will be timely added. Always clean up to replace the filter on the inside the nose to prevent blockage, beware of plastic particles mixed with iron shaw, impurities such as sand, stone to fall within the cylinder, to avoid the damage of screw with a nitrogen-treated barrel. It is strictly prohibited without material space maneuver to turn, in the cylinder, tee, die temperature, that do not meet the requirements can't start the host. Start the main motor, start the motor after speed slowly, after reaching for speed stability; Close the main motor, should slow down after power off. Preheating, heat shoulds not be too long and too high, in order to avoid jams mouth; Conditions can use the automatic temperature control system, set up the tolerance automatic temperature stable, convenient and safe. Plastic film blowing machine use pay attention to the operation of the machine operator can not stand in the front, lest appear accidental injury and operating personnel. When blown film machine feed fight with metal impurities in raw material and operating small tools such as damage to the hard object fall into the barrel of the machine. No gloves when operating rotating machine, in case involved in injury.
