What are the properties and uses of white oil?

White oil, also known as paraffin oil, white oil, or mineral oil, is a high-tech product mainly composed of complex hydrocarbons. According to different uses and extraction techniques, white oil can be divided into industrial white oil, cosmetic grade white oil, food grade white oil, and medical grade white oil.

The physical properties of white oil

Each type of white oil has its unique physical properties, which reflect the intrinsic quality of the product. For example:

Appearance: The appearance of white oil is its color, and the lighter the color, the higher the degree of refinement. However, white oil produced from different crude oils may have different transparency and color even under the same refining conditions, so the depth of refining cannot be judged solely by the depth of color.

Viscosity: Viscosity reflects the internal friction force of white oil and is an important indicator of oil quality and fluidity. Common viscosities include 5, 7, 15, 26, 45, 60, 100, etc. Oils with high viscosity are thicker, have greater internal friction resistance, and have poor fluidity, but the sealing effect of lubricating grease is better.

Flash point: Flash point is an indicator of the evaporation of oil products. The lighter the fraction, the greater the evaporation and the lower the flash point; The heavier the fraction, the lower the evaporation and the higher the flash point. At the same time, flash point is also an indicator of the fire hazard of petroleum products. Under the same viscosity, a higher flash point is better.

Chemical properties of white oil

In addition to physical properties, the chemical properties of white oil are also important. For example:

Chemical performance testing: including oxidation stability, corrosiveness, etc., these tests can ensure the stability and safety of white oil during use.

Test bench testing: By simulating actual usage conditions, the performance of white oil is tested to ensure that its performance meets the requirements in practical applications.

How to choose the appropriate white oil

Choosing the right white oil is important, as different applications require white oils with different viscosities and flash points. For example:

Industrial use: requires high viscosity white oil to provide better sealing effect.

Cosmetics and food: Food grade or cosmetic grade white oil is required, which has a high degree of refinement, low impurities, and good safety.

Medical: Medical grade white oil is required, which has higher purity, is sterile and non-toxic.

Summarize

White oil is a high-tech product, and its physical and chemical properties determine its use and performance. Choosing the appropriate white oil depends on specific usage and requirements.
