A Whole World of Lube

by Suzana

Lubricants are a substance that could be used to reduce friction in between two mutual surfaces which creates less heat due to the continuous contact of these two surfaces. This is what was found in Wikipedia and it makes sense. This is what cnc lubricants does in its natural form and usually the substances associated with these lubricants are for the most part natural. Many applications are optional when it comes to lubrication like cooking with oils to prevent the pan from becoming stuck to the items being cooked. Lube also helps with transporting particles, transmitting forces, and changing the temperature of the surface to either hot or cold.

According to Wikipedia this has been going on for thousands of years. For example, calcium soaps have been discovered in the axles of chariots from thousands of years dating back. In ancient Egypt the pyramids were built by using lube to help shift the blocks of stone and other material into place. In Ancient Rome the choice of lube ranged from olive oil, to rapeseed oils and animal fats. When the industrial revolution came on to the scene this changed everything because of the metallic substances being used during that time. In the early nineteen hundred petroleum oil became the new type of lubricant and it was also during this time that new technology allowed for the purification of lube.

What constitutes a good lubricant base includes many of the following. A high boiling point and low freezing point allow for the lube to stay liquid no matter what temperature it’s in. Good lube also has a high viscosity index, thermal stability, hydraulic stability, demulsibility, corrosive prevention, and a high resistance to oxidation. Mainly lube contains ninety percent base oil which typically is often mineral oil. Other options for base oils include vegetable oil, hydrogenated polyolefins, esters, silicon’s, fluorocarbons, and even water to some degree. Dry lubricants such as graphite, molybdenum, disulfide, and tungsten disulfide. The dry lube is good for high temperatures.

Additives mainly contribute to the performance of the lube and sometimes especially in the automotive industry the ratios can go up to even twenty percent. Depressive compounds allow for the prevention of crystal waxes. Long chain alkylbenzenes only grow small crystals and stop there because the long chain prevents crystal growth. In nineteen ninety-nine thirty-seven million tons of lubricant were consumed in a single year. The large majority of consumerism when it comes to lube could be attributed to the automobile industry, but other industrial, marine, and metal working applications could be attributed as well. Mineral oil is actually derived from crude oil, which is a natural source of lubrication, but synthetic oils are petroleum derived by using synthetic hydrocarbons. Historically whale oil was a common form of lubrication as well in the twentieth century and was mainly used for transmission fluid. Lastly a bio lubricant is a base resource that could be used over and over again. These are usually fats that come from animals.
