Heat Setting

Basically all needle felts at Shandong Aobo are heat-set. 
The residual shrinkage is reduced to a minimum by means of an optimum combination of the decisive quality factors , such as temperature, dwell time and cooling phase.

The controlled process management during the cooling phase ensures that the filter bags will have excellent form stability even under most difficult conditions.

Quality-determining parameters

  • Temperature

  • Reaction time

  • Cooling time

 

Thermal surface treatment

The surface of any needle felt influences the structure of the filter cake, its cleanability as well as pressure drop and the emission.

-          Singed

Three different kinds of treatment are possible: 

  • smooth for adhesive and moist dust

  • medium for universal treatments

  • rough low agglomeration or fine dust

-          Calendering

Through calendering a more compact fiber structure is achieved. This allows a more surface-active separation of dust with lower emission.

 

Protective Impregnation

-          hydrophobic, oleophobic

This treatment makes it more difficult for moisture to penetrate into the needle felt. Thus the risk of excessive dust deposits and caking is reduced.

-          Protection against acids and hydrolysis

Special impregnation based on TEFLON®. This treatment coats the fiber surface, thus providing it with the anti-adhesive character of a PTFE finish.

An oil- and water-repelling effect is produced, and the fibers are effectively protected against acid and hydrolysis attack.

-          Active finish, hydrophobic

Special water-repellent treatment providing a high cleaning and separation efficiency.

Coatings

Through the filter-active coating dust is already separated on the surface. In addition the anti-adhesive surface reduces the adhesive forces between the filter medium and dust cake.

Advantages

  • Optimised cleaning

  • Increased service life

  • High separation efficiency

  • PTFE-Coating, hydrophobic and oleophobic fibers, protection against acids and hydrolysis

  • Primary finish membrane, microporous foam coating, high separation efficiency, easy dust release, hydrophobic and oleophobic

Q:What is the reason for the strong drop in the broken filter bag of the cement mill dust filter bag
The length of the filter will wear out and reduce dust removal efficiency
Q:How can the washing machine's filter bag be clean?
In general, the filter bag of the washing machine can be removed, please read the instructions carefully, even if it is not easy to tear open come down to, as long as don't have much stuff, generally does not affect the quality of washing.
Q:Problem with the washing machine filter bag
You see if the filter is blocked, or the hole in the inner drum is blocked
Q:Is it better to dust the air with a filter or a filter?
If the gas contains more dust in the filter bag, if the filtration precision is higher the filter core is required. If the dust is high and the precision is high, the filter cartridge will be used before using the filter cartridge.
Q:What is the correct way to 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:What is the filter principle of the high performance filter bag?
The network structure of nanofibers can reduce the thickness and line density of the supporting filter, thus reducing the pressure loss and improving the efficiency of production.
Q:How to remove the filter bag of semi-automatic washing machine?
Filter the plastic card button down, and gently pull out!I hope my answer will help you.
Q:Why is the filter bag material PE a polyester, not a polyethylene
Polyester: the general name of a polymer compound that is condensed by diglycol or polyols and dibasic acid or polyacid. Include polyester resin, polyester fiber, polyester acid glue etc. Polyester, Polyethylene terephthalate (PET) belong to the high molecular compound. Consists of terephthalic acid (PTA) and ethylene glycol (EG) through polycondensation produce polyethylene terephthalate (PET), part of the PET and ultimately generated by underwater pelletizing. Purpose: fiber grade polyester chip is used to make polyester staple and polyester filament, which is the raw material for fiber and related products of polyester fiber. Polyester film and bottle, and other purposes at the same time, widely used in packaging industry, electronic appliances, medical and health care, construction, automotive and other fields, the packaging is one of the largest non polyester fiber application market, is also the fastest growth in PET. It can be said that the polyester slice is an important intermediate product that connects the petrochemicals and the products of several industries.
Q:How is the filter bag chosen?
Second, if the protecting temperature degrees must be dropped to below 150 ℃ higher investment or restricted by the site; Three is due to gas containing dust because of containing sulphur ingredient, in protecting gas with acid "" dew point "protecting gas can only be in the form of acid dew point temperature is high above the filter elements such as separation, under so much demand have a chemical fiber can endure high temperature dust removal filter bag filter material used to make dust removal."
Q:How do you use a filter bag?
In order to improve the use of filter bags, we should pay special attention to this knowledge in ordinary times. If we have different problems, we need to find solutions. First, the bag is broken. The shape of the filter bag and the installation method of the filter bag determine the location of the filter bag easily broken, which can be inspected and repaired. Secondly, the filter bags age. For reasons that are caused by the following reasons, reasons should be investigated, taking the elimination measures and changing the filter bags. (1) hardening and contracting due to unusually high temperature; (2) due to contact with the vapor of an acid, alkali or organic solvent; 3) react with water.
