Today, worldwide, industrial maintenance and repairs account for a significant portion of the costs, most of which are related to rusted and worn metal structures. Corrosion of metal surfaces encompasses a wide range of industries and equipment and incurs irreparable costs. These include: pipelines, oil tanks and storage of petrochemicals, power plant structures, piers and offshore platforms, ship hulls, water treatment systems, etc. Although corrosion of metal surfaces is a natural and inevitable phenomenon, but with proper implementation of protection and coating operations on these surfaces, its destructive effects can be greatly reduced and repeated and heavy costs can be avoided.
In this regard, it is very important to prepare the surfaces (rust, grease and other contaminants) before applying the protective coating layer. Exfoliation of the contaminated surface should be done without damaging the surface so that the coating and paint applied on the surface are highly durable. Gradual loss of coating ordiscoloration is the main cause of corrosion and subsequent damage.
Today, in the world, serious attention has been paid to sandblasting operations, both in the field of machinery and in choosing the type of abrasive with a scientific and up-to-date attitude. For example, in the prestigious universities of the world, chairs have been created in this field and standards have been defined for it. In this regard, Persian Garnet has introduced efficient, quality, environmentally friendly and unique abrasives for the market, which with its many advantages, can be a suitable alternative to abrasives such as ore, aluminum oxide, glossbide, etc.
