TAPPI TIP 0502-15 provides practical selection criteria for ceramic materials 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, thermal conductivity, and material characteristics affect machine performance.
It compares commonly used ceramics, including aluminum oxide, zirconia, silicon nitride, silicon carbide, and zirconia-toughened alumina, and identifies their relative advantages, limitations, and suitability for different papermaking zones. Application tables support material selection for open forming, two-wire consolidation, sheet transfer, and high-vacuum areas under varying lubrication, drag-load, mechanical-abuse, and abrasive-filler conditions.
Application Scope: For papermakers, paper machine designers, maintenance engineers, ceramic suppliers, and technical personnel evaluating wet-end ceramic components and forming-section applications.
