I. What is Paraffin-based Petroleum?
Paraffin-based petroleum is a kind of blended oil formed by mixing wax-containing paraffinic petroleum solvents and wax-containing fractions in a certain proportion. Its main components are paraffin series compounds and wax alkyl hydrocarbons. Paraffin-based petroleum is generally a colorless and transparent liquid with a relatively low density, and it has a high flash point and volatility.
II. Characteristics of Paraffin-based Petroleum
High Wax Content
A remarkable characteristic of paraffin-based petroleum is that it contains a relatively high proportion of waxy substances. These waxy substances are mainly long-chain alkanes, which make paraffin-based petroleum prone to crystallize and form waxy solids at low temperatures.
Low Pour Point and Cloud Point
Due to the high wax content of paraffin-based petroleum, its pour point and cloud point are relatively low. The cloud point refers to the temperature at which petroleum begins to solidify, while the pour point refers to the temperature at which petroleum begins to have poor flow under standard conditions. The low pour point and cloud point enable paraffin-based petroleum to maintain good fluidity in a low-temperature environment.
Good Lubricity
The waxy substances in paraffin-based petroleum endow it with excellent lubricating properties. This makes paraffin-based petroleum an important raw material for manufacturing industrial oils such as lubricating oils and cutting fluids.
High Chemical Stability
Paraffin-based petroleum is relatively stable chemically and is not easy to react with other substances. This enables it to maintain good performance stability during the storage and use processes.
Environmental Friendliness
Although paraffin-based petroleum is relatively environmentally friendly during the production and use processes, attention still needs to be paid to the treatment and recycling of its waste. Reasonable treatment and recycling of waste paraffin-based petroleum products help to reduce the impact on the environment.
III. Uses of Paraffin-based Petroleum
Industrial Lubrication
Paraffin-based petroleum is widely used as a lubricant in the industry. Its good viscosity and wear resistance make it an ideal lubricant for various mechanical equipment. It can effectively reduce the friction and wear between mechanical components and extend the service life of the equipment.
Rust Prevention and Corrosion Protection
Paraffin-based petroleum also has good rust prevention and corrosion protection properties. It can form a protective film to prevent the metal surface from coming into contact with oxygen and water vapor in the air, thereby avoiding metal corrosion and rust. Therefore, paraffin-based petroleum is often used in the manufacture of rust-proof oils and anti-corrosion agents.
Chemical Production
Paraffin-based petroleum is a raw material for manufacturing some special chemicals. For example, it can be used to make slow-release pesticides and plant protectants to improve the yield and quality of crops. In addition, paraffin-based petroleum can also be used to make daily consumer goods such as candles and shoe polish.
Medical Applications
In the medical field, paraffin-based petroleum also has its unique applications. It is often used as the base of ointments for skin care and the treatment of mild skin lesions such as burns and wounds. In addition, paraffin-based petroleum can also be used as a part of pharmaceutical preparations or a carrier agent to help the drugs exert their effects better.
Agricultural Films
Paraffin-based petroleum containing special additives can be made into agricultural films, which are covered on the ground surface to reduce water evaporation and increase the soil temperature. This kind of film helps to improve the soil environment and promote the growth and development of crops.
Lubricating Oils
Paraffin-based petroleum is also widely used in automotive engine lubricating oils. It can be used as a base oil to meet the special requirements of vehicles for engine oil, such as good oxidation resistance, wear resistance, and thermal stability. Lubricating oils using paraffin-based petroleum as the base oil can effectively protect the engine and extend its service life.
Rubber Plasticizers
Paraffin-based petroleum can also be used as a plasticizer for rubber. It can reduce the viscosity of rubber, improve the processing performance of the rubber compound, and is conducive to the dispersion of fillers and other additives in the rubber matrix. At the same time, paraffin-based petroleum has a positive impact on the physical and mechanical properties of rubber.
