The characteristics and advantages of the three-roll calender are as follows:
Features:
1. Compact structure: the three rollers are closely arranged and occupy relatively small space, which is convenient for layout on the production line.
2. Uniform temperature distribution: It can ensure that the sheet is heated evenly during the calender process to avoid local overheating or undercooling.
3. High precision roller surface: After fine processing, the surface is smooth, which helps to achieve high quality calender effect.
Advantages:
1. Significantly improve the surface quality: make the surface of plastic sheet more smooth and flat, reduce defects and roughness, improve the appearance quality of products, and meet the requirements of high application scenarios, such as high-end packaging materials.
2. Enhance product performance: Through uniform pressure and temperature control, it can reduce the internal stress of the sheet and enhance its physical properties, such as strength and toughness.
3. High production efficiency: continuous operation, can quickly handle a large number of sheets, improve the production speed and output.
4. Flexible operation: According to different materials and process requirements, flexible adjustment of roller temperature, speed and pressure parameters.
5. Good stability: The equipment runs stably and the failure rate is relatively low, ensuring the continuity and stability of production.
For example, in the production of plastic film, the three-roll calendering machine can give the surface of the film a better gloss and transparency, making it more attractive when packaging food; In the production of plastic sheet, it can effectively improve the flatness and dimensional accuracy of the sheet, so that it can be better fitted and installed in building decoration.
