Abstract: Problem of rusting on the machines and heavy engineering machine setup in the industrial manufacturing plants of various companies is very common. Most of the machines in fabric dyeing companies ,chemical Plants ,leather tanneries, tool manufacturing units and gear manufacturing industries having the rust on them. When industrial machine setup becomes too old and due to the continuous interaction with chemicals like dyes, acids ,bases and bleaching agents and polluted waste water.This rust material increases rapidly on water supply pipelines, weight scales, water boilers and iron made heavy engineering machines. When it is not continuously monitored and controlled by the maintenance staff of the company. Other reasons of rapid rusting are release of acidic fumes and hot water vapours which rapidly corrodes and damages the outer and inner surfaces of machines. One of the most important reason of industrial rusting is exposure to atmospheric moisture during the production processes in the manufacturing plants.
Generally development and deposition of rust stains and rust on ceramic surfaces occurs when they are in close contact with rusted iron and water and oxygen which is universally present in the atmosphere everywhere. The rust spots becomes more and more stubborn due to its deposition on the same place for long time and continuous ignorance by us. Today ceramic items are available in the market in different material types like vinyl, porcelain, granite, marble and travertine. Due to the high water absorption capacity of ceramic and porcelain tiles and materials they are at more risk of having rust. Such type of rust stains may be removed very easily by applying the paste of slight acids and salts and then scrubbing the stains.
