T-1805 Fuel oil fluidity improver(PPD)
1. Product introduction
T1805 fuel 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.
2. How to use
1) The addition amount of T1805 is generally below 0.1%, and most refineries add 0.02-0.06%.
2) The effect of use depends not only on the performance of the improver itself, but also closely related to the oil used and the refining process. In order to achieve a better use effect, it is necessary to test before use, determine the configuration plan, and then use it formally.
3) Before use, mix T1805 into concentrate fluid, use kerosene as the diluent, dilute at a ratio of 1:15, and add the prepared concentrate fluid to the diesel or fuel oil to make T1805 product and diesel evenly mixed to achieve best effect.

5. Precautions for safe use
Precaution
.Closed operation, full ventilation.
.Keep away from fire, sparks and high heat.
.Adopt anti-static measures when filling, and ground and connect the container and receiving equipment;
. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment.
.It is recommended to use explosion-proof ventilation systems and equipment.
.It is recommended that operators wear filter-type gas masks (half masks) and anti-static overalls.
.It is forbidden to discharge polluted water into water bodies.
Incident Response
In case of skin or hair contact, remove contaminated clothing and rinse skin with water
Ingestion: Do not induce vomiting and seek medical attention.
. Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained portable respirators and anti-static overalls. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and drains.
.Small leakage: Use sand or other non-combustible materials to absorb or absorb. It can also be washed with a lot of water, and the washing water is diluted and put into the waste water system. A large number of leaks: construct a dike or dig a pit for storage. Cover with foam. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
. Move the container from the fire scene to an open place as much as possible. Spray water to keep the fire container cool until the end of the fire extinguishing.
.Extinguishing methods: alcohol-resistant foam, dry powder, carbon dioxide, sandy soil.
Safe Storage
.Store in a dry, cool and ventilated warehouse.
.Keep away from fire and heat; keep the container tightly closed. The storage temperature should not exceed 40ºC. Place it alone, avoid turning it upside down, and prevent it from collapsing or falling.
.Keep the product clean and prevent the mixing of moisture and impurities.
.Should be stored separately from oxidants and reducing agents, and avoid mixed storage.
.It is recommended to use explosion-proof lighting and ventilation facilities.
. Avoid using mechanical equipment and tools that are prone to sparks.
. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
Disposal
This product or its container is recommended to be disposed of by incineration
