Innovative plastic processing technology - twin-screw extrusion granulation line leads the new trend of PP open masterbatch production
With the rapid development of the plastics industry, PP (polypropylene) open masterbatch plays an increasingly important role in the processing of plastic products due to its excellent anti-adhesion properties and lubrication properties during processing. PP open masterbatch, which is composed of a variety of highly efficient special additives, can not only effectively reduce the adhesion of polyolefin plastic products, but also play a lubricating role in the processing process, and will not affect the transparency of the product.
The application range of PP open masterbatch is extremely wide, especially in food packaging, industrial packaging, daily chemical light industry and other fields, PP composite film, tissue film, food film and other products can be seen. The principle of action is that a layer of extremely lubricated film is formed on the surface of the plastic product, while a convex and convex structure is formed at the microscopic level, which significantly improves the opening performance.
In the process of producing PP open masterbatch, temperature control is particularly critical. Although the specific temperature parameters are not explicitly provided in the search results, in general, the processing temperature range of PP materials is between 180 ° C and 240 ° C, which helps to ensure the effective melting and mixing of PP materials.
The core of all this is the twin-screw extrusion granulation line. The production line adopts the building block principle design, and the screw structure can be replaced according to different process requirements to achieve efficient mixing and reaction of materials. The precision screw size design and full engagement design ensure that the gap between the material and the screw barrel is smaller, thus ensuring the quality and uniformity of the material reaction.
The working principle of the twin-screw extrusion granulation line is to successively pass through the stages of feeding, melting, melt conveying, mixing, exhaust, homogenization and metering extrusion. This process involves not only the change of physical state, but also the precise control of energy consumption, pressure establishment and temperature distribution. The scientific and reasonable combination of screw components plays a vital role in improving the mixing effect, product quality, production efficiency and reducing energy consumption.
With the continuous progress of technology, the twin-screw extrusion granulation line has shown its unparalleled advantages in the production of PP open masterbatch, which not only improves the production efficiency, but also ensures the excellent quality of products, which has brought revolutionary changes to the plastic processing industry.
As the leader of plastic processing technology, twin-screw extrusion granulation line is leading PP open masterbatch production to a new height with its high efficiency, energy saving and environmental protection characteristics. We have reason to believe that it will continue to play an indispensable role in the future development of the plastics industry.
