I. Product Introduction
The product mainly comprises low molecular weight olefin derivative solution. DKJ-JN serial pour point depressants and wax resisting settling agents can mutually react with wax components in diesel oil and therefore inhibit wax crystallization, thereby improving low-temperature fluidity.
The low-temperature fluidity of the diesel oil is usually characterized by two physical indexes, cold filter plugging point and freezing point, with cloud point also being one important physical index for the diesel oil. As the temperature lowers, straight-chain paraffin in the diesel oil will crystallize to large-size diamond-shaped crystal ribbons together with the wax in the pour point depressant crystallize with straight-chain n-alkane to make the shape, size and amount of the crystals changed.

III. Directions for use
1. The product can substantially increase the fluidity of the diesel oil, improve crystallization of the wax, and prevent formation of connected network structure due to the crystallization of the wax, thereby reducing CFPP and PP.
2. Amount of agent added is in the range of 50 to 1000mg/kg, and the real amount of the agent added is decided by the composition of the diesel oil.
3. The DKJ-JN serial pour point depressants can be directly added into the diesel oil or after dilution, with temperature being 40 to 50 ℃ during the adding process. The solvent suitable for dilution is diesel oil or aromatics solvent.
IV. Package and Storage
1. The product is packaged by 200L barrel, net weight of each barrel being 180kg.
2. The product can be kept for at least one year, with storage temperature not exceeding 40 to 50 ℃. Short time exposure at the temperature of lower than 70 ℃ can not affect performance of the product.
