In chemical and pharmaceutical industries, baghouse dust collectors are used to capture and filter out airborne pollutants generated during the manufacturing processes. These pollutants can include fine powders, fumes, and other hazardous substances that pose a risk to worker health and safety.
The baghouse dust collectors used in these industries typically utilize a range of filter bag materials depending on the type of process and the nature of the pollutants being generated. Some common filter bag materials used in chemical and pharmaceutical applications include polyester, polypropylene, PTFE (Teflon), and fiberglass.
Polyester and polypropylene filter bags are often used in chemical and pharmaceutical applications because they offer good chemical resistance and can handle high temperatures. These materials are also relatively cost-effective, which makes them a popular choice in these industries.
PTFE (Teflon) filter bags are another popular option in chemical and pharmaceutical applications because they offer superior chemical resistance and can withstand high temperatures. These bags are often used in processes where acidic or caustic substances are being used.
Fiberglass filter bags are also commonly used in chemical and pharmaceutical applications, especially in high-temperature processes. These bags offer superior resistance to heat and can handle temperatures up to 260°C (500°F).
In summary, baghouse dust collectors are essential in chemical and pharmaceutical industries to control air pollution and protect worker health and safety. The choice of filter bag fabrics depends on the type of pollutants being generated and the operating conditions of the process. Materials such as polyester needle filter felts, polypropylene, PTFE needle felts, and fiberglass woven fabrics are commonly used in these industries due to their chemical resistance and ability to handle high temperatures.
