Q:How can the filter bag be processed later?
Dust filter bags can be processed according to specific requirements. Yiqing ash treatment Adopts the patent technology production Yi Qing ash density and breathable, needled felt filter material itself has a good soot cleaning performance, and can work long hours under high filtration velocity. Antistatic processing In certain concentrations, some dust occurs when a spark burns or is generated by friction. Therefore, it is suitable for inflammable and explosive dust to be used in the needle felt filter. Antistatic filter is used to describe the mixing of the filter fibers The conductive fibre (including the dual conductive fibre, graphite-conductive fibre and stainless steel conductive fibre) enables the whole filter to conduct electrical conductivity
Q:What is the correct way to use a filter bag
Third, the cloth should not hang too loosely or too tightly, too easily to accumulate dust, too close to pull out. Fourth, new process old filter bag should not be mixed, avoid damage time different effect equipment normal work
Q:How to clean the filter bag of electrophoresis
Dry first, clean up the electrophoresis paint in it, then soak overnight in ultrafiltrate, then rinse with ultrafiltrate. The best way to do this, though, is to replace a new filter bag.
Q:How do you use a filter bag?
Fifth, replace the filter bag, blow clean with compressed air first, check for broken holes, and then replace when the holes are repaired. If the filter bag is filled with dust, rinse with water and leave after cooling. Sixth, the filter bag is blocked. When the filter bag is blocked, the resistance is raised, but the reading of the differential gauge is displayed. The filter bag jam is the main cause of the wear, perforation and loss of the filter bag.
Q:Can liquid filtration bags be cleaned and reused
Deep depth with felt filter material, filtering is a compound intercept model, namely the larger particles impurities trapped in the fiber surface, and tiny particles are trapped in deep in the filter material, so the filter with high filtration efficiency. Deep filtration cannot be cleaned and reused.
Q:How clean is the bag filter bag
According to the mechanism of liquid filtration process, surface filtration and deep filtration are classified.
Q:How to remove the washer filter bag
Remove the water from the washing machine and use a screwdriver to press down the square hole above the filter door. Hold the plastic pipe and pull out the sewage flow, although it is ready for a container of water, which is then inserted into the sewage stream. Restore the sewage pipe. Go counterclockwise to remove the filter bag. Rinse with water. Put it back in place and rotate clockwise.
Q:What is the fabric of a filter bag?
Twill weave: it is made up of two roots, the warp threads of four, which are interwoven with the weft, and the interwoven threads of the warp threads are moving to the left or to the right. Twill weave and double twill; Twill weave of flexible and flexibility are better than the plain weave, slightly lower mechanical strength, easy dislocation after stress, but its good abrasion resistance, and dust removal efficiency and the effect is good, is the most commonly used one kind of woven fabric organization;
Q:Who has used a liquid filter bag? What is its feature?
1, good heat resistance, can be used under 280 ℃ for a long time Dust is easy to peel off
Q:Why is the filter bag material PE a polyester, not a polyethylene
It is divided into high density polyethylene, medium density polyethylene and low density polyethylene according to the density. Polyethylene is a high polymer chain that is connected by a repeat - CH2 - unit connection through the addition and polymerization of ethylene (CH2 = CH2). Purpose: polyethylene insoluble in water, water is very small, is about some chemical solvents, such as toluene, acetic acid, etc., and only showing modest dissolved when temperature above 70 ℃. But polyethylene particles shape, can be between 15 ℃ and 40 ℃ melting or solidification, along with the change of temperature at higher temperatures melt, absorbing heat; When the temperature drops, it solidifies, releasing heat. Because it absorbs little water, it is not wet, it has insulation, so it is a good building material.
