Diesel pour point depressant, also known as diesel pour point depressant, is an additive used to reduce the pour point of diesel. In a low-temperature environment, the freezing point of diesel will increase, causing the diesel to be unable to flow, affecting the starting and operation of the engine. Diesel pour point depressant can improve the flow performance of diesel in low temperature environments, maintain the liquid state of diesel, and ensure normal engine operation.
Working principle
The main function of diesel pour point depressant is to reduce the freezing point of diesel by changing the crystalline form and crystal size of diesel. At low temperatures, the wax in diesel fuel can form tiny crystals, causing the diesel fuel to become viscous and solidify. Diesel pour point depressant can combine with wax to change the crystal shape and size, thereby lowering the freezing point of diesel and maintaining its flow properties.
Application fields
Diesel pour point depressants are mainly used in the following fields:
- Diesel fuel additives: Diesel pour point depressants can improve the low-temperature flow performance of diesel and ensure that the engine starts and operates normally in low-temperature environments.
- Petrochemical industry: Diesel pour point depressant can be used as an important raw material in the petrochemical industry to produce various lubricating oils and fuel oils.
Advantages and Notes
Advantages of diesel pour point depressants include:
- Significantly lower the freezing point of diesel and improve low-temperature flow performance.
- Good compatibility with other additives and will not have a negative impact on the engine.
When using diesel pour point depressant, you need to pay attention to the following matters:
- The usage amount of diesel pour point depressant should be adjusted according to the actual situation to avoid excessive use.
- Diesel pour point depressant should be stored in a cool, dry, well-ventilated place, away from direct sunlight and high temperature.
