PVC plastic is a multi-component plastic, and different additives can be added according to different uses. Due to different components, PVC products exhibit different physical and mechanical properties, which are suitable for different applications. Carry Technology has integrated 13 rules for PVC pipe production operations for everyone:
1.Before starting the extruder, check for foreign objects inside the barrel, upper and lower parts of the hopper, and inside. Check for loose fastening bolts in all parts, secure safety covers, and correct position of button switches. Then, add sufficient lubricating oil to each lubrication area and ensure proper cleaning and hygiene of the equipment.
2.When preparing to drive, notify the staff around the equipment.
3.Start the motor at low speed to drive the screw rotation. Check whether the pointer of the main motor’s working ammeter swings normally. If there is any abnormal sound or unstable screw operation during equipment operation, stop the machine immediately and seek relevant personnel for repair and resolution.
4.The trial run of the screw during idle operation should not exceed 3 minutes. After everything is normal, install the mold. Use connecting bolts to install the mold. Before use, apply a layer of molybdenum disulfide or silicone oil to facilitate disassembly.
5.In the early stage of feeding production, the screw should use the lowest working speed, and the feeding should be small and uniform. At any time, check if there are any abnormal changes in the pointer of the working ammeter of the motor that drives the screw rotation.
6.After the extruder is put into normal production work, the operator should regularly check the temperature changes in the bearing area. When checking the temperature of the motor and various bearing parts, gently touch the inspection area with the back of your fingers. Do not touch any rotating parts with your hands during the operation of the equipment.
7.When disassembling and installing screws and molds, it is not allowed to directly strike the parts with a heavy hammer. If necessary, hardwood should be used to strike during disassembly or installation.
8.When cleaning the residues on the screw, barrel, and mold, bamboo or copper knives and brushes must be used for cleaning. Steel knives are not allowed to scrape the residues or barbecue the parts with fire
9.When dealing with extruder malfunctions, the extruder must not be driven. When the extruder screw rotates and the mold is adjusted, the operator must not face the extrusion barrel mouth to prevent accidents from occurring.
10.During the production of the extruder, the operator is not allowed to leave the post. If it is necessary to leave, the extruder should be stopped.
11.After parking, disassemble the screw and clean the residue. Apply a layer of rust proof oil. If not in use temporarily, wrap it up and hang it vertically in a dry and ventilated place.
12.Extruders and forming molds that have been out of use for a long time should be coated with anti rust oil and sealed at each inlet and outlet to prevent foreign objects from entering.
13.PVC specialized high-efficiency additives can effectively combine with the friction and lubrication of the extruder to make the extruder operate efficiently and extend its service life. It is important to remember to choose specialized additives.
