In the pharmaceutical or biotechnical field, equipment maintenance is an important aspect of keeping a workspace in top shape.A common problem with equipment in these fields is known as ‘rouging’.Most equipment used by professionals contains stainless steel, and after several months of regular use a rust color will appear on equipment surfaces.Derouging is the process that must be undertaken to clean these surfaces totally.Following the cleaning, preventative steps should be taken to guard against the occurrence of rouging in the future.Regular inspections will also help decrease the amount of rouge that can form on equipment.
Alkaline cleaning and rinsing are preformed primarily to remove any rouge.Once this process is complete, the next phase will be started.To put it simply, a layer of chromium oxide is applied to the surface of any equipment being dealt with.This process is known as passivation, and is an important safeguard against the formation of rouge.Once the rouge has been removed, this preventative safeguard measure can be begun.Certain chemicals may increase the amount of chromium oxide that is applied to the equipment.The higher these levels, the more protection the surface will have against the future formation of rouge.
The entire process of passivating stainless steel is a very involved and precise undertaking, involving several steps but ending with dramatic results.Unfortunately, however, the process itself is not a permanent solution.High levels of heat, nicks and scratches will both cause the protective layer to degrade more quickly.Even if the equipment is unused, time will eventually take its toll on the chromium oxide layer.When these effects wear off, rouging will appear again.The only way to effectively safeguard against unwanted rouging is to carry out regular repassivation to help maintain and replace the chromium oxide that protects the equipment’s surface.
Regular maintenance featuring precision cleaning and repassivation will help any type of equipment maintain its sheen.Guarding against corrosion and oxidization is important in any field, especially pharmaceuticals.Relying on a professional, experienced company to deliver repassivation at regular intervals is the only way to guarantee that equipment will stay in the best shape possible for years to come.And the process isn’t relegated to just steel, either.A wide number of different materials can be protected in this manner.The chemicals used can be hazardous, and the process is complex, making it difficult and dangerous to attempt alone.Skilled professionals can handle any size job and deliver lasting results.
