1.What is the diesel oil fluidity improver？
A diesel oil fluidity improver is a specialized additive used to enhance the low-temperature properties of diesel fuel. Diesel fuel tends to thicken and form wax crystals at cold temperatures, which can lead to issues with fuel flow, filter plugging, and difficulty starting engines in cold weather conditions.
The fluidity improver, also known as a cold flow improver or winter diesel fuel additive, works to modify the wax crystal formation and prevent or reduce fuel gelling in cold temperatures. It achieves this by altering the size, shape, and structure of the wax crystals, allowing them to remain small and more dispersed in the fuel, even at lower temperatures.
2.The key functions of a diesel oil fluidity improver include:
①Lowering the pour point
The pour point is the lowest temperature at which the diesel fuel can flow. A fluidity improver reduces the pour point, ensuring the diesel remains liquid and can flow smoothly in cold conditions.
②Improving cold filter plugging point (CFPP)
The CFPP is the temperature at which the fuel can start to clog fuel filters. The additive lowers the CFPP, preventing filter plugging and ensuring a continuous supply of fuel to the engine.
③Preventing fuel line blockages
By modifying the wax crystal formation, the fluidity improver helps prevent fuel line blockages and ensures uninterrupted fuel flow to the engine’s fuel system.
④Enhancing low-temperature operability
By improving the low-temperature properties of diesel fuel, the additive enables reliable engine starting and smooth operation even in freezing temperatures.
3.What is the T1805 diesel oil fluidity improver？
T1805 diesel oil pour point depressant uses ethylene and vinyl acetate as the main raw materials, adds a third monomer to improve the charge of polar groups, and adopts a high-pressure solution polymerization production process, plus a suitable dispersant.
For the carbon distribution of diesel wax in use, we adjust the molecular weight of the improver polymer and the distribution of molecular chain polar groups and the types of polar groups to make the gap between the polymer polar groups and the carbon number of the paraffin wax crystals.
Matching, the addition of a strong polar group to the polymer molecular chain improves the polarity of the polymer, increases the van der Waals force between the crystals, the particle size of the paraffin crystals is smaller, and the cold filter plugging point of the diesel oil is greatly reduced.
T1805 diesel flow improver series products can reduce the cold filter plugging point and pour point and achieve the purpose of improving the low-temperature flow performance of diesel and fuel oil.
4.What the importance of diesel oil fluidity improver？
Diesel oil fluidity improvers are particularly important in regions with cold climates, as they help optimize the performance of diesel engines and equipment during winter months. The appropriate dosage of the additive depends on the specific diesel fuel formulation, operating conditions, and the severity of the cold temperatures.
It’s crucial to use diesel oil fluidity improvers that are compatible with the diesel fuel and comply with the engine manufacturer’s recommendations. Proper storage and handling of diesel fuel, as well as regular maintenance, are also essential to ensure the optimal performance of diesel engines in cold weather conditions.
