What is hydraulic fluid?
hydraulic fluids are liquids used as a motif medium in a hydraulic machine and equipment. These fluids are used in various machines, including cars. Car transmission, power steering and power brakes require hydraulic fluids. The brake fluid, the subtype of the hydraulic fluid, is specially made to have a low freezing point, a high boiling point and hygroscopic capabilities, so it absorbs water. Hydraulic fluids are also used in tractors, excavators, forklifts, bums, bulldozers, garbage cars and other industrial machines. Most aircraft flight control systems also require hydraulic fluid.
Hydraulic fluids contain numerous chemical compounds, including oils, esters, silicones, butane, polylylenenonglycols (PAG), corrosion inhibitors and many others. However, the three most common types of chemicals used in hydraulic fluids are polyalphalefins (PaO), phosphate esters and mineral oil.
Fortunately SOUEarly interest in the protection of life environment created the demand for biobaized and biodegradable hydraulic fluids. Biodegradable hydraulic fluid has the basic supplies of vegetable oils such as soy, rape, rape or sunflower. These biobic fluids help minimize pollution in case of oil leakage.
These biodegradable fluids are an important progress because the chemicals used in conventional hydraulic fluid may be extremely rough on the environment. When leakage or leakage occurs, some of the chemicals remain at the top of the soil, while others fall into groundwater. If the fluid escapes into the water body, some chemicals sink to the bottom where it can remain for more than a year. Fish and other sea life, which lives in contaminated water, can absorb hydraulic fluid. Unfortunately, biodegradable hydraulic fluid is much more expensivethan conventional fluid, so these biobased fluids are not widely used.
People can be exposed to chemicals in hydraulic fluid by touching it, swallowing or breathing air near the machine that uses it. The exposure may also occur by touching the contaminated soil or water. Currently, there is not much known about how exposing air to hydraulic fluid affects human health. The ingestion of these fluids can cause bleeding in the intestine, pneumonia or death. Workers who regularly process hydraulic fluids reported the weakness of the hands. If one has prolonged contact with most hydraulic fluids, there is a possibility of skin irritation.
hydraulic fluid becomes dangerous when heated to the ignition point, spraying or evaporated. Proper storage requires that the hydraulic fluid is stored in closed metal containers and the storage of large quantities should be done correctly. Rags and garments soaked in hydraulic fluid shouldalso be contained in closed metal containers to prevent the possible fire danger and disposed of correctly.
