What are the three 3 types of base oil?
There are three types of base oils: mineral, vegetable, and synthetic. Mineral oil comes from crude oil and the quality depends on the refining process.
What is the specific gravity of base oil?
Advantages
| BASE OIL(I-SN150) | ||
|---|---|---|
| Characteristic | Unit | value |
| Specific Gravity @ 15.6 | 0.872 | |
| Sulphur Content | %wt | 0.2 |
| Tan | mgKOH/g | <0.05 |
What is the difference between group 1 and group 2 base oils?
Group I base oils are the most common type used for industrial oils, although increasingly more Group II base oils are being used. Group II base oils are created by using a hydrotreating process to replace the traditional solvent-refining process.
What is the density of base oil?
Specification of Group 1 Base Oil.
| SN 70 | ||
|---|---|---|
| 1 | Flash point | Min 174 |
| 2 | Pour point | Max – 6 |
| 3 | Density at 15 °C | 0.85 |
| 4 | Viscosity @40°C | Min 8.5 |
What is Group 4 base oil?
Group IV base oils are polyalphaolefins (PAOs). These synthetic base oils are made through a process called synthesizing. They have a much broader temperature range and are great for use in extreme cold conditions and high heat applications.
What is a Group 4 oil?
Group IV. Group IV base oils are synthetic base oils that composed of polyalphaolefins (PAOs). These products have a viscosity index of 125-200. These base oils are not extracted from crude oil, but made from small uniform molecules.
What does specific gravity of oil indicate?
Specific gravity is an index used to measure the density of a liquid. Specific gravity is calculated as the ratio of the density of a liquid to the density of water. So any liquid with a density greater than water has a specific gravity greater than 1.
Why specific gravity of oil is important?
In applications with higher specific gravity, more torque would be required to produce the desired result. If specific gravity was not taken into consideration, and a mixer not optimized accordingly, results would be unpredictable, and motor damage and/or failure would likely occur.
What is Group V base oils?
Group V base oils are any base oil that is not classified as a Group I-IV base oil. Common Group V base oils are polyalkylene glycols (PAGs) and various esters. One exception is white oil, which is a very pure lubricant commonly used in cosmetics and food processing.
What is cSt base oil?
(2) Viscosity is a measure of a fluid’s resistance to flow. Often-used measurement units are cSt at 100℉. According to specific speed, temperature, and load condition required for machine and equipment, different viscosity of lubricants is needed.
What is SN 150 base oil?
Base oil SN 150 is known as a light grade base oil at the lower end of the specifications for Grade I light base oils. It is mostly used in lubricant and lubricant additives production. It is a Group I base oil which has undergone solvent refining processes.
What is virgin base oil?
Crude oil that has gone through the process of refining is referred to as virgin and is the mostly commonly used oil found within a wide spectrum of lubricant products on the market. Virgin oil is newly refined, meaning that it has not been previously used and it sets the bar for oil quality.
