ポリプロピレンPP金網デミスター
Polypropylene PP wire mesh demister is a high-performance lightweight gas-liquid separation device, woven from polypropylene (PP) material, designed for gas mist separation in corrosion-resistant, low-temperature environments. This product is suitable for complex working conditions such as strong acids and alkalis, corrosive gases, and waste gas treatment, and is a common choice in environmental protection, chemical, electroplating, chlor-alkali and other industries.
Compared with traditional metal demisters, PP wire mesh demisters are lighter, lower in cost, and have excellent corrosion resistance. They can efficiently intercept droplets and mist, thereby protecting subsequent equipment and optimizing system operating efficiency.

製品の特徴と利点
Excellent chemical resistance
PP material can withstand a variety of acid and alkali media and is not eroded by corrosive gases, making it an ideal gas-liquid separation solution for electroplating, pickling and other industries.
Lightweight design, easy installation
Polypropylene has low density, the weight of the whole set of defoamer is only 1/4 of the stainless steel defoamer, which is suitable for high-altitude towers, plastic towers and other equipment with high weight requirements.
Economic and environmental protection, easy to replace
Low cost, long service life. Easy to clean, can be reused many times, reduce maintenance costs, green environmental protection.
High separation efficiency and low pressure drop
Fine mesh structure to achieve more than 98% mist removal efficiency, and large gas flux, pressure reduction, does not affect the system air volume or pressure balance.
Flexibility in customization
LiandaFiltration can provide customized PP defoamer design according to customer’s tower size, gas velocity, media type and other parameters.
製品応用産業

Environmental protection engineering: waste gas treatment equipment, acid and alkali tail gas treatment tower, wet desulfurization system
Pharmaceutical and food industry: secondary droplet separation in clean gas systems
Plastic equipment matching: ideal matching components for non-metallic structure equipment such as polypropylene towers and PVC towers
よくあるご質問
The recommended upper temperature limit for polypropylene is 90°C. Exceeding the temperature may cause structural deformation. If high temperature conditions are required, please consider stainless steel or PTFE as an alternative.
When the separation efficiency drops significantly or the pressure drop increases significantly, it may be caused by blockage. You can try cleaning first. If the performance does not recover, it is recommended to replace it.
Yes. Polypropylene can be washed with water or alkali solution without corrosion damage, and can be recycled many times under normal use conditions.
Whether it is compatible with PP material depends on the type of solvent. Generally, it has a certain resistance to low-polarity solvents. If the medium is complex, you can contact LiandaFiltration for material compatibility recommendations.
Of course. We support non-standard customization, including circular, elliptical, segmented assembly, special-shaped tower structures, etc., to meet the tower installation needs of different customers.
