The used twin-screw parallel rod extruder has the principle of the extruder of a single-screw extruder: solids transport, melt pressurization and pumping, mixed stripping and de-evaporation, but it is not just that. The study of its extrusion process is roughly divided into three links:
连系。 1. It is necessary to find out the actual situation of the physical changes of two or more polymers and materials in the extrusion process, the mixing shape, the process of structural change, and the connection between the final mixture and function .
2. As a used twin-screw parallel rod extruder, the internal relationship between the reaction process, speed, function and screw configuration and operating conditions during extrusion reaction molding is established, and a model is established to guide the reaction molding extrusion.
3.The used twin-screw parallel rod extruder has lasting reliability
Below we introduce the advantages of using the used twin screw parallel rod extruder:
1.Intuitively understand the wear of wearing parts
Because it is easy to open, the wear level of the threaded components and barrel liner can be found at any time, so that effective repair or replacement can be performed. Don't find out when there is a problem with the extruded product, causing unnecessary waste.
2. Improve labor efficiency
When repairing equipment, ordinary used double-screw parallel rod extruders often have to remove the heating and cooling system first, and then pull out the screw as a whole. The split type twin screw is not needed, just loosen a few bolts, turn the worm gear box handle device to lift the upper part of the barrel to open the entire barrel, and then perform maintenance. This not only shortens maintenance time, but also reduces labor intensity.
3.High torque and high speed
At present, the development trend of used twin-screw parallel rod extruders in the world is toward high torque, high speed, and low energy consumption. The effect of high speed is high productivity. Split-type used double-screw parallel rod extruder belongs to this category, and its speed can reach 500 rpm. Therefore, it has unique advantages in processing high-viscosity and heat-sensitive materials.
4. Reduce production costs
When manufacturing master batches, it is often necessary to change the color. If it is necessary to change the product, open the open processing area within a few minutes. In addition, the mixing process can be analyzed by observing the melt profile on the entire screw. Split-type used twin-screw parallel rod extruder can solve this problem. When changing the color, the barrel can be quickly opened for manual cleaning in just a few minutes, so that no or less cleaning material is used, which saves costs.
5.High output, high quality, rate
It has the other advantages of ordinary used double-screw parallel rod extruder, which can realize high output, high quality and rate.
