TAPPI TIP 0502-15 2011 provides practical selection guidance for ceramic components used in paper machine wet ends. The document explains how wear resistance, forming fabric abrasion, surface finish, edge sharpness, toughness, thermal shock resistance, frictional heat stress, and material properties affect performance.
It compares commonly used ceramics, including aluminum oxide, high-density aluminum oxide, zirconia-toughened alumina, zirconia, silicon nitride, direct-sintered silicon carbide, and liquid-phase silicon carbide. Tables summarize the relative advantages and disadvantages of each material and identify suitable options for open forming zones, two-wire consolidation zones, sheet transfer areas, and high-vacuum applications.
This concise technical reference is intended for papermakers, mill engineers, maintenance teams, ceramic suppliers, and other professionals evaluating wet-end materials for wear, fabric protection, mechanical durability, thermal performance, and operating conditions.
Application Scope: Selection and evaluation of ceramic materials for paper machine wet-end components, forming sections, sheet transfer areas, and high-vacuum papermaking applications.
