UHMWPE absorbent box covers are core components of the vacuum absorbent box in the wire section of papermaking machines. With their superior comprehensive performance, UHMWPE absorbent box covers are gradually replacing traditional metal and ceramic panels, becoming the preferred product for energy saving, consumption reduction, and efficiency improvement in the papermaking industry. This product uses UHMWPE raw materials with a molecular weight ≥3 million, molded and sintered, and features absorbent holes or grooves on the surface, adapting to the vacuum dewatering needs of various papermaking equipment.

The core advantages of UHMWPE absorbent box covers are their excellent wear resistance and low-friction self-lubricating properties, which significantly reduce the running resistance and wear of the forming wire, extending the wire's service life by more than 30%, while reducing drive energy consumption. With a water absorption rate of less than 0.01%, it is resistant to papermaking white water, acid and alkali corrosion, and shows no rust or swelling even after long-term immersion, effectively solving the corrosion and leakage problems of traditional metal covers. Furthermore, the product is lightweight and impact-resistant, with a density only 30% that of metal, making it easy to handle and install. It does not crack in low-temperature environments and can withstand the impact of high-speed paper and water flow.

UHMWPE absorbent box covers are widely used in vacuum absorbent boxes of high-speed tissue paper machines, cultural paper machines, and packaging paper machines. Custom sizes, hole types, and thicknesses can be made according to customer drawings, and anti-static and flame-retardant modifications are also available. The UHMWPE absorbent box covers are manufactured using a molding and sintering process, ensuring uniform board density and precise hole positioning. Leveling and fixing are required during installation, and regular cleaning of the holes is all that is needed, resulting in low maintenance costs.
