Do You Know The Four Classifications Of MWFs?


castrol syntilo 9930Metalworking fluids are necessary to prevent corrosion and overheating within industrial equipment, truck fleets, and planes. They're what keeps your machines running efficiently and with little downtime for optimal productivity.

However, not all metalworking lubricants are created equal. For instance, the Castrol Syntilo 9930 doesn't work the same as Braycote 601 or an Aeroshell 64.

Metalworking fluids are each grouped into four different classifications. These classifications are ultimately based on their composition. To refresh yourself or to learn more about how these industrial lubricants are composed, consider the following classifications.

  1. Synthetics
    Synthetic lubricants contain no oils, but rather additives for greater heat removal and corrosion resistance. Most synthetics are diluted with water, specifically between 10 to 40 parts. Many of those in the construction industry choose to use synthetics because they're considered more environmentally friendly. This is because synthetic metalworking fluids are cleaner than mineral oils.

  2. Semi-synthetics
    Compared to synthetic lubricants which contain no oil, semi-synthetic lubricants contain less than 30% oil content in concentrate. Semi-synthetics additionally contain performance-enhancing additives and emulsifiers. Like synthetics, they've also been diluted with water.

  3. Soluble oils
    Soluble oils contain a greater amount of oil than semi-synthetics. Although they can sometimes contain 30% oil, they most often contain 50% to 85% oils. Soluble oils are also mixed with emulsifiers and other additives while being diluted with water.

  4. Straight oils
    Also known as mineral oils, straight oils are made of refined lubricant-base oils and aren't diluted with water. In some cases, they may contain performance-enhancing additives.

It should be noted that while not all four classes of metalworking fluids are diluted with water for performance, they all contain additives to enhance their performance. These additives often include emulsifiers, detergents, biocides, surfactants, anti-weld agents, etc. In some cases, certain additives may be used to control pH level.

It's necessary to know these different classifications of metalworking fluids when selecting oil solutions. After all, the wrong lubricant used for the job could cause more problems than it solves.

Industrial supplies like Castrol Syntilo 9930 and other metalworking lubricants are necessary for an efficient industrial business. For more information on specialty lubricants, transportation lubricants, and other corrosion preventatives, contact Santie Wholesale Oil Company today.
