Antiscalants prevent precipitation of crystallized mineral salts that form scales inside boilers. In boilers, scaling is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent.
In most instances corrosion in condensate system occurs in the decreased pH of condensate owing to dissolution of carbon dioxide gas in steam into the condensate, which is called carbonic acid corrosion.
Oxygen scavengers are added to enclosed packaging to help remove or decrease the level of oxygen in the package. They are used to help maintain product safety and extend shelf life.There are many types of oxygen absorbers available to cover a wide array of applications.
Corrosion inhibitor is a material that attaches or coats the metal surface, providing a protective barrier film, which in turn stops the corrosive reaction from developing. Temporary coatings are often used to prevent corrosion during storage and shipment, and between machining or processing operations.
