What should we pay attention to when producing food grade PTFE filter bags?

1. PTFE filter bag can identify dust, polyester polypropylene and vinyl bags in food, pharmaceutical and other industries. PTFE filter bag protects health and side effects.

2. PTFE filter bag cutting, iron ironing, good warp and weft yarns, loose sewing threads should use the same performance thread.

3. Before using PTFE filter bag, the food and pharmaceutical industries use warm water (according to the concentration) to quickly clean the dirt on the surface of the fabric. The main body of the fabric softens the hydrophobic permeable filter cloth, and the utilization rate of the PTFE filter bag is also increased.

4. When producing special specifications of products, increase and decrease the diameter of the optional filter bag.

Generally, PTFE filter bag is selected according to the nature of the dust-containing gas, the nature of the dust and the cleaning method of the dust collector. The high temperature PTFE filter bag system has an excellent failure standby mode, which is different from electric dust removal. For example, if the electrostatic precipitator fails the pump in a certain electric field, the transmission of the electric field pump can be stopped. Changes in temperature will affect the resistivity of dust, etc. This will not affect the operation of other electric pumps and facilitates maintenance.
