What kind of raw materials are selected to complete the production of filter cloth has a significant influence. The wear resistance of the products made of glass fiber is relatively low. The dust is removed by flue gas reverse blowing. This ash removal method requires that the filter press's filter cloth meet the requirements of mechanical filtration, etc. It should be noted that the materials used for different filter materials are also different.

The working condition of the boiler is related to the production quality of polyester filter cloth. Mistakes in work may even lead to purification failure. It is because the abnormal situation has not been dealt with promptly. For example, too high a smoke temperature will lead to bag burning, abnormal humidity will lead to bag pasting, etc. Besides, the leakage will also increase the whole flue gas's oxygen content and even cause the bag to oxidize, thus becoming brittle..

When the filter cloth machine just started running, some dust can be smeared to form a powder layer's protective layer. It is necessary to stop the machine's operation during dust collection to prevent the residual dust and dew from combining into an acidic solution and damaging the filter cloth.
