Best Practices: The Use of Fiberglass Reinforced Plastic In Pulp and Paper Processing

摘要

Fiberglass reinforced plastic (FRP) made from epoxy vinyl ester resin is the preferred material of construction for piping, ductwork, tanks, hoods, scrubbers, and stacks in pulp and paper processing plants. The conversion of wood to paper requires the use of highly corrosive bleaching chemicals that have proven to be far too harsh for conventional materials such as stainless steel and tile linings. Furthermore, FRP provides a considerably more economical alternative to high nickel alloys and other expensive specialty metals. The purpose of this paper will be to explore the diverse applications of FRP in pulp and paper processing and compare it to corrosion resistant metal alternatives.
