PPH Packed Tower

The quality PPH packed tower of Xinda Chemical is specially designed for highly corrosive gas-liquid mass transfer processes and is suitable for harsh scenarios such as absorption of chemical waste gas and desulfurization of acidic gases. The tower body is made of high-crystallinity polypropylene homopolymer (PPH) through a spiral extrusion winding process in one piece, achieving a weld-free and high-strength integral structure, which can fundamentally solve the corrosion and leakage problems of traditional metal or fiberglass reinforced plastic materials.

The tower can be filled with high-efficiency packing materials, providing a huge gas-liquid contact area to ensure the efficient purification and recovery of corrosive waste gases such as hydrogen chloride and sulfur dioxide.The surface of the equipment is smooth and not easy to scale, and the long-term operation is stable. It is an ideal choice to replace the traditional tower and improve the reliability and life of the system.

Why is PPH material good as packed tower?

PPH (High crystallinity Polypropylene homopolymer) is a high performance plastic specially developed for harsh industrial environments.Its key advantages over ordinary polypropylene (PP) are significantly improved temperature resistance, creep resistance and long-term chemical resistance.The material is more crystalline and has a more regular molecular structure, which leads to greater mechanical strength and is able to maintain a stable shape at higher temperatures and pressures, making it less prone to deformation.Under the long-term erosion of strong acid, strong alkali and a variety of organic solvents, PPH packed tower shows better resistance and longer service life than ordinary PP, especially suitable for the manufacture of chemical equipment that needs to be integrated, withstand a certain internal pressure and has high sealing requirements, such as large storage tanks, tower and vacuum measuring containers.

Application fields

Material properties and structural characteristics

The core material of the PPH packed tower is polypropylene homopolymer (PPH), which features strong corrosion resistance, high-temperature resistance and excellent mechanical properties. This material demonstrates excellent stability against over 95% of chemical media (such as acids, alkalis, salts, etc.) and can operate stably for a long time within the temperature range of -10°C to 90° C. Its impact strength and tensile strength are also significantly superior to those of ordinary polypropylene materials. In terms of structural design, the PPH metering tank adopts a one-time forming process, with no welds and good integrity, effectively avoiding the risk of leakage. At the same time, through special structural optimization, it achieves an efficient vacuum effect, meeting the process requirements of metering, storage, etc.
