As the development of industry in recent century, massive machine has been used in the progress of production. Lubricant is a essential material to reduce the friction in industrial application. But what can be used as lubricant? Why is it important for us to find the answer to the question of what can be used as lubricant?
To answer the question what can be used as lubricant, first, we need to know that what is lubricant. A lubricant is a substance introduced to reduce friction between surfaces in mutual contact. In industrial applications, lubricants are used for many other purposes.
Second of all, generally lubricants are based on one type of base oil, but mixtures of the base oils also are used to meet performance requirements. Usually, vegetable oils is the first answer that jumps to our heads when it comes to the question of what can be used as lubricant. The use of vegetable oils and animal fats for lubrication purposes has been practiced for many years. With the discovery of petroleum and the availability of inexpensive oils, alternatives became unattractive and were left by the wayside.
Over the past two decades, a renewed interest in vegetable oil-based lubricants has occurred as environmental interest has increased. In Europe during the 1980s, various mandates and regulations were placed on petroleum products necessitating the use of biodegradable lubricants. During the 1990s, many American companies began developing biodegradable products. The next decade will recognize more advances in the use of biodegradable lubes and greases than in any other time in history. More and more people started to reconsider the question of what can be used as lubricant under the consideration of environmental issue.
Therefore, it is not difficult for us to realize the reason that we have to pay attention to the question of what can be used as lubricant is not only about the product itself, but also about the consequence we have to consider carefully when we produce lubricant and apply the use of lubricant in all the industries.
