Natural and Chlorosulfonated Polyethylene Rubber Coatings for Anticorrosion Protection in Reducing and Oxidising Chemicals, and in Natural and Industrial Conditions

摘要

The corrosion behaviour of a natural rubber of TM type, of a compound with 25percent natural rubber and 75percent chlorosulfonated polyethylene (CSPE) of PR-7 type and of two CSPE rubbers of CSPE-E (cross linked with epoxy resin) and of CSPE-L (cross linked with litharge) type as simple vulcanising sheets and as coatings (linings) on carbon steel was studied in laboratory, natural and industrial conditions. The experimental results enabled the usefulness of these materias to be defined in terms of corrosion media, temperature range and duration of effectiveness. The perofrmances of rubbers both in reducing and in oxidising chemicals increase with increasing CSPE rubber content and the content of ingredients, the best resistance being shown by the CSPE-L type rubber.
