Zinc oxide (ZnO) is widely used in rubber, ceramics, coatings, and pharmaceuticals. Its production typically involves high-temperature processes such as indirect (French) or direct (American) methods, which release fine particulate dust and metallic vapors into the air. To ensure environmental compliance and protect downstream equipment, efficient dust filtration systems are crucial.
Among the available filter media, Nomex® (Aramid) filter bags are particularly well-suited to the demands of the zinc oxide industry.
Nomex is a meta-aramid fiber developed by DuPont, known for its outstanding thermal stability and chemical resistance. Below are the properties that make it a preferred material in ZnO dust collection:
Nomex filter bags are widely used in the following parts of a zinc oxide plant:
Application Area | Challenge | Why Nomex Works |
---|---|---|
Furnace exhaust collection | High temperature (180–220°C) | Excellent heat resistance |
Cyclone or baghouse filters | Fine ZnO particles, potential clogging | Stable airflow, surface treatment compatible |
Metal vapor filtration | Possible corrosive vapors | Chemical resilience |
To further improve filtration performance in ZnO applications, Nomex filter bags can be:
The high-temperature, chemically active environment in zinc oxide manufacturing demands filter bags with superior endurance. Nomex filter bags offer the right combination of thermal resistance, filtration efficiency, and durability, making them a cost-effective and technically sound solution for the ZnO industry.
At Omela Filtration, we provide customized Nomex bag solutions with options for membrane coatings, reinforcement, and optimized sizes — ensuring long service life and environmental compliance.
Dust filter bags are at the heart of any baghouse dust collector system. Their efficiency, lifespan, and performance directly dete
