The PP PS sheet extrusion line developed by Jwell is used to produce multi-layer composite environmentally friendly sheets. The sheet mainly blisters various food containers and packaging, such as trays, noodle bowls, lunch boxes, cake boxes, and fruit trays.
The equipment can effectively use the proportion of stone powder, reduce the cost of sheet material, improve the degradability of the sheet, and ensure the comprehensiveness of the sheet.
PP PS feature introduction and industrial application
PP——polypropylene is a kind of lightweight thermoplastic synthetic resin with excellent performance, chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good wear-resistant processing properties.
After PP undergoes chemical modification, physical modification, and transparency modification, the colorability, processability, and impact resistance will become better.
PP has a wide range of applications: fiber products (clothing, blankets), auto parts, chemical containers, food, and drug packaging, etc.
PS-polystyrene, including ordinary polystyrene, expanded polystyrene (EPS), high-impact polystyrene (HIPS), and syndiotactic polystyrene (SPS).
Ordinary polystyrene is a colorless and transparent particle with excellent heat insulation, insulation, and transparency, and easy to color.
Application areas: building materials industry, automobile industry, packaging industry, etc.
PP sheet has high transparency, good barrier properties, low density, non-toxic and hygienic, and can be recycled and will not produce toxic and harmful gases when heated and burned.
Mainly used for packaging and stationery of food, medicine, medical equipment, etc., such as processed jelly boxes, dairy product packaging boxes, cold drink containers, fast food boxes, microwave oven appliances, stationery tablets, folders, etc.
PS is similar to PP in performance, and it also performs well in food packaging. Because of its low static electricity generation, it is mostly used in electronic product packaging.
PP PS sheet extrusion line model selection
In the current market, the PP PS sheet extrusion line is mostly single-screw models, because the equipment cost is much lower than that of twin-screw models.
Jwell’s PP/PS single-screw model has stable feeding and can plasticize the raw materials well under a variety of different formulations, ensuring the toughness of the sheet and avoiding the easy heat forming of the sheet in the later stage. Problems such as cracking and uneven color.
In the production of PP sheets, the Jwell single-screw model is currently capable of stable production up to 1.5 tons per hour.
Although the cost of the twin-screw model is higher, it is better than the single-screw in other aspects.
Twin-screw, the design flexibility of its thread structure is stronger, which ensures the extruder’s feeding, and at the same time makes the formula material have better dispersion in the barrel, and the sheet material will be more uniform.
PP PS sheet extrusion line equipment features
1.Whether it is a single screw or a twin screw, there is a design that meets the production of PP and PS at the same time.
The single-screw machine lengthens the ratio of length to diameter and increases the vacuum exhaust;
The twin-screw machine adds a vacuum system to ensure the full discharge of material water vapor and ensure the performance of the sheet.
2.The winding adopts two structures of traditional winding machines or a fully automatic winding machine to meet the needs of customers for ordinary small-volume production and large-capacity production, and directly help customers reduce labor costs.
In addition, the fully automatic winding machine has no jamming in the cutting of thick sheets, and there is no phenomenon that it cannot be wound.
3.The efficient and stable control system makes the pressure and speed of the PP PS sheet extrusion line more stable.
The precise control system makes the equipment more comfortable in improving the output and performance of the equipment.
PP PS sheet extrusion line control system
The PP PS sheet extrusion line adopts Siemens frequency conversion, servo control, and Ethernet transmission technology control to achieve high efficiency, high precision, high stability, and high safety.
The 100M/s high-speed network transmission reduces the error caused by the transmission between the control system and the drive and makes the equipment more efficient.
HMI man-machine interface, centralized control system, realizes one-screen browsing of the whole machine system parameters, such as current, pressure, speed, temperature, etc., making the operation easier.
