In general, a surface which requires protective coating from wear, corrosion  and rust, a coat of rubber lining is applied. The lining of rubber is mostly applied to inner surfaces of the container. The surface to be rubber lined has to be cleaned by sandblasting to white metal. When the old lining to be replaced, surface decontamination may be required prior to sandblasting. Then the surface will be coated with adhasive with the help of a brush or roller. The adhesive. coating consists generally of two to three coats of different adhesives. Then rubber is applied by cutting the rubber sheet to fit to the shape of the surface to be lined and adhering it to the surface. Care is taken to remove any air trapped between surface and the rubber sheet. A special care to be taken for this. For pipe linings, a specialised methods are followed. Then the rubber along with the surface to be cured or in other words vulcanised in autoclave or under cover of steam or hot air. The final inspection consists of spark testing the lined surface by a high voltage which detects any pin holes in the lining and if it is found they has to be repaired and retested before putting the surface in required service.

Rubber Lining -
Applications and Materials

What is Rubber Lining?

Rubber lining is the skilled application of unvulcanised rubber sheet to prepared metal surfaces. The lined items are then vulcanised in a steam autoclave, fully bonding the rubber to the metal surface creating a durable and resilient protective rubber coating.

The rubber coating can be from 2mm to 50mm thick depending on the application, and can be bonded to mild steel, stainless steel, cast iron and aluminum.

Benefits

The principal benefits of rubber lining are its excellent resistance to corrosive and abrasive chemicals and materials, e.g. acids, alkalis, salt water, slurries, sand, shotblast media, crushed rock etc. In addition rubber linings provide other benefits including noise and vibration reduction, electrical and thermal insulation and product protection.
