IMPERVIOUS CARBON AND GRAPHITE BRICKS & TILES It is made from low ash,hard calcined grade carbon/electro-graphite powder which are selected carefully and mixed with bituminous binders in varying proportions. The mix is then extruded or moulded as per requirement and heated to high temperatures in a furnance. The stock material formed has high porosity around 25%. since its mechanical strength and abrasion resistance is not adequate, the product is impregnated with resins of unmatched chemical resistance, in vacuum autoclaves depending on duty service. The final material is thus made impervious to liquids and gases. This process greatly improves all physical properties such as compressive and impact strength, abrasive resistance, bringing down porosity of the brick to minimum. The process though cumbersome has found to be unique in combating any chemical attack of corrosion and abrasion at elevated temperatures. It has been established that impervious carbon is an excellent material of construction especially in areas where process conditions are highly corrosive and abrasive above 700C range, where most of the rubber linings and plastics start attaining their distortion temperature and tend to harden and crack gradually. Impervious carbon and graphite materials withstand continously temperatures up to 1900C and such linings have been known to be working for years, trouble free.
