| Summary, etc | Detailed investigations were carried out on the ageing behaviour of air dried sheet rubber prepared using sulphuric acid as coagulant, in comparison with that of sheets prepared using formic acid. Long term thermo-oxidative ageing of vulcanizates prepared from the sheets was also studied. Observations have also been made on the extent of corrosion on coagulation pans and sheeting rollers for a period of two years. It was found that decrease in the strength of raw rubber sheets prepared with sulphuric acid was negligible over a period of one year. Ageing behaviour of vulcanizates from sheets prepared using sulphuric acid was comparable to those prepared using formic acid, if the recommended conditions of use are followed. Corrosion of aluminium pans and sheeting rollers was negligible, when sulphuric acid was used as coagulant and recommended practices were followed. |
