PP three-phase separator special board

The special PP board (polypropylene board) for three-phase separators requires a series of specific properties due to its special application environment in oil, water, and gas separation processes. The following are its main characteristics and detailed explanations:

1. Corrosion resistance

Chemical stability: PP board has excellent resistance to acids, bases, salts, organic solvents, etc., especially suitable for handling oil and gas mixtures containing corrosive media (such as H ₂ S, CO ₂, etc.).

Application scenarios: Suitable for corrosive environments such as petroleum, chemical, and wastewater treatment.

2. Temperature resistance

Working temperature range: usually -10 ℃ to+80 ℃, short-term can withstand 100 ℃ (adjusted according to additives).

Low temperature brittleness: Pure PP may become brittle at low temperatures, and its cold resistance can be improved through copolymerization modification (such as PP-B or PP-R).

3. Mechanical strength and wear resistance

Rigidity: PP board has higher hardness, but not as good as metal. It needs to be reinforced with fibers (such as glass fiber) or thickened to improve its pressure bearing capacity.

Wear resistant: The surface is smooth and not prone to scaling, but when subjected to long-term particle erosion, high wear resistant modified PP (such as adding UHMWPE) should be selected.

4. Lightweight and easy to process

Low density (0.91-0.93g/cm ³), easy to transport and install.

Weldability: Seamless splicing can be achieved through hot melt welding, reducing the risk of leakage.

5. Aging resistance

UV protection: When used outdoors, anti UV agents should be added to prevent degradation by sunlight.

Antioxidant properties: Long term exposure to air requires the selection of stabilized PP materials.

6. Surface characteristics

Hydrophobicity: PP surface is not easily attached to water phase, promoting oil-water separation.

Low surface energy: reduces dirt deposition and facilitates cleaning and maintenance.

7. Environmental Protection and Safety

Non toxic: Meets food grade standards (such as FDA certification) and is suitable for separation equipment in the food industry.

Recyclable: Waste PP boards can be melted and regenerated, meeting environmental requirements.

8. Typical application scenarios

-Oilfield produced fluid treatment (separation of oil, water, and sand).

-Three phase separation after chemical reaction.

-Separation of oil and water in the food industry.

Through reasonable material selection and design, PP board can effectively balance cost, performance, and lifespan in three-phase separators, making it an ideal choice to replace metal or fiberglass.
