The Corrosion Resistant UHMWPE Absorbent Box Cover is a high performance wear component specifically engineered for paper mill dewatering board applications. This precision manufactured cover is designed to fit over absorbent boxes in the forming section of paper machines providing excellent wear resistance and corrosion protection. Made from ultra high molecular weight polyethylene, this cover extends the service life of dewatering equipment while maintaining consistent paper quality and production efficiency.
Exceptional Corrosion Resistance The UHMWPE material exhibits excellent resistance to dilute acids alkalis alcohols ketones greases and oils commonly found in paper mill environments. Unlike metal components this cover will not rust or corrode when exposed to aggressive chemicals and process water.
Superior Wear Resistance This absorbent box cover offers up to six times better abrasion resistance than steel significantly extending service life in high wear applications. The material withstands the continuous abrasive action of paper stock and fillers.
Low Friction Surface With a coefficient of friction of 0.1 to 0.2 the cover reduces drag on the forming fabric minimizing fabric wear and reducing drive load requirements. This self lubricating property ensures smooth operation without external lubrication.
Moisture Proof Performance With water absorption of less than 0.01 percent the cover maintains dimensional stability even when fully submerged. The material will not swell deform or lose mechanical properties in wet conditions.
Precision Groove Processing Custom groove patterns are precisely machined into the cover surface to optimize water drainage and dewatering efficiency. The grooves can be customized to match specific paper machine requirements.
Impact and Fatigue Resistance The high impact strength of UHMWPE protects against damage from debris and shock loads. The material exhibits no notch sensitivity and virtually unlimited fatigue life.
Weight Reduction At a density of 0.93 grams per cubic centimeter the cover is significantly lighter than traditional metal components making installation and maintenance easier.
This UHMWPE Absorbent Box Cover is specifically designed for the following paper mill applications.
Forming section dewatering boards
Absorbent box covers in fourdrinier paper machines
Foil boards and forming board covers
Paper machine wear components
