Abstract

The parent described a process for vulcanising a material or synthetic rubber and sheet by incorporating a part of the vulcanising system into the new sheet during its prodn and coating the rubber at a later stage with a soln of the second part of the vulcanising system in a solvent which allows migration of that second part into the sheet. The sheet can thus be stored and vulcanised in situ after application to any desired, substrate to give good adhesion and perfect sealing. In this patent the process is applied to the prodn of plates or articles of any shape and thickness starting from a single rubber sheet of standard thickness. The process is useful e.g. for producing abrasion resistant elastomeric linings for e.g. shaking or vibrating sieves grinding mills, cyclones, sand separator etc. Process results in homogeneous vulcanisation throughout the rubber layer(s).
