The common materials for the dewatering element cover of paper machines include high molecular weight polyethylene (UHMWPE) and ceramics, both of which have their own advantages in different process stages:
High molecular weight polyethylene (UHMWPE)
Wear resistance: The wear resistance is 6-7 times that of carbon steel, suitable for high-strength dehydration environments and reducing equipment wear.
Corrosion resistance: resistant to acid and alkali corrosion, stable performance in humid environments, and low maintenance costs.
Self lurication: Smooth surface, reduces fiber adhesion, and improves dehydration uniformity.
Lightweight: Lightweight, simplifying installation and maintenance processes.
Ceramics
Wear resistance: Ceramic materials such as alumina and zirconia have more outstanding wear resistance and are suitable for high vacuum and high pressure dehydration zones.
Stability: resistant to high temperature and high pressure, with a long service life, but heavy in weight.
1. The overall structure with high precision machining can effectively avoid paper diseases caused by the retention of small fibers and the phenomenon of top pulp, and extend the service life of the forming fabric and press felt.
2. The overall surface is flat, smooth, and delicate. During use, a water film is formed between the forming fabric and the dewatering element, which improves wear resistance and greatly reduces the driving energy consumption of the forming fabric and press felt. This improves the service life of the forming fabric and press felt and saves electricity.
3. When in use, the dehydration efficiency is high, the water line is easy to control, and there will be no instantaneous positive and negative pressure pulses during dehydration, avoiding top pulp and avoiding unfavorable formation of paper sheets during the dehydration process, reducing the difference between the two sides of the paper, and greatly improving the uniformity and smoothness of the paper.
4. Has a unique corrosion-resistant material that is suitable for various dehydration and papermaking environments.
