5, as per the temperature is partitioned into: (1) low temperature class: reasonable for unrefined substance factory, concrete plant, the top and lower part of the distribution center and other neighborhood dust raising point sack type dust authority use, and for high dampness content circumstances additionally need to utilize oil-safe waterproof treatment specialist on its surface for surface treatment; (2)filter cloth supplier ordinary, high temperature class: appropriate for concrete vertical oven, revolving oven furnace tail, cooling machine, dryer and other high temperature fumes gas treatment pack type dust gatherer, and for high temperature, high dampness content circumstances likewise need to utilize oil-safe waterproof treatment specialist on its surface for surface treatment;.
Attributes
For channel fabrics, what influences their administration life isn’t just the mileage of the actual material, yet more critically the consumption of the channel fabric by the functioning substance, in this way, the necessities as modern channel materials are extremely high and chiefly need to have the accompanying qualities.
(1) Good catching impact after solids and long help life.
(2) Fast filtration speed, less obstructing and stable filtration rate.
(3) Good slag stripping, no extending and great layered soundness.
Choice
The choice of channel material is vital and assumes a significant part during the time spent filtration. Whether or not the determination of channel material is sensible straightforwardly influences the impact and speed of filtration.
- The decision of channel material should be founded on the idea of the slime and the size of the particles to meet its filtration to actually catch the muck particles, fundamentally for the size of the pore size of the channel fabric and its penetrability (air porousness), and so on
2, as per the muck PH worth to pick various materials of channel fabric, for the most part to draw out the help life of channel material, polypropylene series channel should be utilized in pH 4 ~ 8 climate, nylon series channel material should be utilized in pH 5 ~ 8.5 climate.
3、Choose channel fabrics with various rigidity and prolongation rate as per the size of filtration pressure.
4、When the filtration execution of two sorts of channel material is comparative, the expense of channel fabric ought to be thought of.
