Hard chrome is a type of plating primarily used in industrial applications to protect metal object against wear and corrosion. It also gives the metal objects better aesthetics. But in order for chrome to provide these benefits, it must be properly maintained.
Maintaining hard chrome requires regular cleaning. Chrome provides good protection against corrosion due to the chromium oxide that forms on the surface. The oxide creates a barrier that prevents further oxidation from occurring. Dirt buildup on the chrome surface can prevent the oxide from completely covering the surface. It also has the tendency to absorb moisture from the air and effectively delivering it to areas of the chrome that is not protected by the oxide. Regular cleaning helps prevent such problem.
A lubricating oil can be used to clean the chrome surface. Like most lubrication products, oil is attracted to metal. As the oil moves toward the metal surface, penetrates into the dirt buildup and loosens it. The loosened dirt can then be easily removed by wiping or brushing.
Be careful when cleaning chrome. Some cleaning agents are too aggressive and strips off the protective oxide on top of the chrome. Regular use of these cleaning agents can cause the chrome plating to thin out.
Lubricating oil can also be used to protect chrome from scratches. By increasing the lubricity of the chrome surface, hard objects that come in contact with it will slide on top of the chrome instead of digging into the plating and chipping or scratching it.
Certain elements of lubricants can pose danger to the environment and the health of the people. It is crucial to learn about the toxicity of the components used in lubricating substances like lubricant oil and grease in order to identify its danger.
The base oil is the key part lubricating oil and grease. The American Petroleum Institute, the biggest trade association for the oil and natural gas industry in the United States classifies base oils into five different groups. Oils belonging to Group I and II oils are something to be very careful of.
The Group I oils consist of compounds recognized as polycyclic aromatic hydrocarbons. These substances are present in nature and can also be manufactured. The y are found in coal, tar and also other sorts of oils. These compounds are contaminations that have been left behind after the refining procedure and the reason oils coming from group I are considered to be carcinogenic.
The Group II oils are explained as being mildly hydrotreated. Although there are no human data that exist for these substances, researches involving animals have produced results suggesting possible carcinogenicity for oils belonging to this group.
In using lubricants that contain base oils belonging to Group I and Group II, it is important to assess the chances of the lubricants coming in contact with the environment and how it can be prevented or minimized.
