Pao synthetic fluid
| Oil glossary |
Polyalphaolefins, often called synthetic hydrocarbons, are probably the most common type of synthetic base oil used today. they are moderately priced, provide excellent performance and have few negative attributes. pao base oil is similar to mineral oil. the advantage comes from the fact that it is built, rather than extracted and modified, making it more pure. practically all of the oil molecules are the same shape and size and are completely saturated. the potential benefits of paos are improved oxidative and thermal stability, excellent demulsibility and hydrolytic stability, a high vi, and very low pour point. most of the properties make paos a good selection for temperature extremes – both high operating temperatures and low start-up temperatures. typical applications for paos are engine oils, gear oils and compressor oils. the negative attributes of paos are the price and poor solubility. the low inherent solubility of paos creates problems for formulators when it comes to dissolving additives. likewise, paos cannot suspend potential varnish-forming degradation by-products, although they are less prone to create such material.

- A measure of the degree of molecular motion of a material compared to a reference point. temperature is measured in degrees farenheit (melting point of ice = 32 º f, boiling point of water = 212 º f) or degrees celsius (melting point of ice = 0 º c, boiling point of water = 100 º c).
- The degree of sensible heat of a body as measured by a thermometer or similar instrument.

Paper chromatography, английский

Pag synthetic fluid, английский
Polyalkaline glycol have excellent oxidative and thermal stability, very high vi, excellent film strength and an extremely low tendency to leave deposits on machine surfaces. the low deposit-forming tendency is really due to two properties – the oil’s ability to dissolve deposits and the fact that the oil burns clean. so when they are exposed to a very hot surface or subjected to micro-dieseling by entrained air, pags are less likely to leave residue that will form deposits. pags may also be the only type of base oil with significantly lower fluid friction, which may allow for energy savings. the other unique property of pags is the ability to absorb a great deal of water and maintain lubricity. there are actually two different types of pags – one demulisifies and the other absorbs water. the most common applications for pags are compressors and critical gearing applications. the negatives of pags are their very high cost and the potential to be somewhat hydrolytically unstable.
