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.

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
Antistatic Constructions
electrical conductive
Optimum discharge of electrostatic charges, therefore suitable for potentially explosive areas, as well as for electrostatic, strongly chargeable/charged dusts.
permanent electrical conductive in accordance with DIN 54 345 part 1 by adding stainless steel fibres into the fibre mass in accordance with DIN 54 345 part 1 or

Company Information
- Q: What is the quality inspection of the filter bag?
- The advantages and disadvantages of the filter bag are related to various factors, but mainly depend on the filter material. Dust filter bag filter material is synthetic, natural fiber or glass fiber woven cloth or blanket, according to the design of the filter need to sew cloth or blanket cylinder or flat shape filter bag, according to the nature of flue gas, choose the suitable for the application premise of filter material, usually, in the flue gas temperature is below 120 ℃, filter material with acid resistance and durability of the case, often selects the polyester wool and polyester fiber needled felt, in the treatment of high temperature flue gas (< 250 ℃), the main use graphitization glass wool cloth, in some special cases, choosing carbon fiber filter material, etc.
- Q: How can you not damage the filter bag when the filter bag is installed?
- The dust filter bag has a great effect on the dust removal effect, and the filter bag must not be damaged by the installation. 1 should pack the filter bags to the installation location and install one of them. The filter bag cannot be dragged carelessly on the board, to prevent the metal burrs from the surface of the filter bag, and damage the filter bag. Remove from the packing box until it is installed to the orifice of the flower plate, not touching any metal or surface roughness. Use the protective cover provided by the supplier when using the orifice, in case the filter is touching the plate hole.
- Q: How about all the filters in the washing machine
- It's better than buying a new filter bag to put the stockings on a plastic stent that's broken
- 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: What is the correct way to use a filter bag
- The cloth bag dust collector needs to have the filter bag in the process, and the filter bag is usually bought according to different usage environment. Of course, we should pay special attention to this area in order to improve the use of filter bags. 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
- Q: Which is the liquid filter bag?
- Liquid filter bag quality is good, pay attention to is to see the efficiency of the filter cloth, pore size distribution, density, porosity, fracture strength, thickness, weight, etc. A series of technical indicators.
- Q: How is the filter bag chosen?
- About high flue gas temperature compare, such as: chemical, carbon black (white carbon black), and iron blast furnace gas, cement kiln, and factory of calcium carbide kiln tail gas, forging, steel mills, asphalt concrete mixing asphalt smoke, refractory brick kiln gas, coking gas, etc., one is because of these gas containing dust dust because of restricted by resistivity is not suitable for electrical dust collector to collect, can only use dust filter bag or other methods to collect;
- Q: What do you notice when the filter bag and dust collector are installed?
- Installation filter filter bag filter bag method is to filter by housing plate hole into the bag in the room, and then put the upper mouth of the spring coil to knead into a pit, in the case of orifice plate medium, neutralizing spring coil again, make it tight pressure tight in the hole on the circumference of a circle, finally the bag cage from mouth gently insert, until the upper part of the filter bag cage cover is pressure on the casing plate hole.
- 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 do you check the filter material of the filter bag?
- Filter bag dust filter core, its quality directly reaction precipitator dust removal efficiency and service life, in order to ensure the quality of filter bag, cope with the production of filter bag filter material for sampling, determine its performance up to standard. The filter material needs to be tested and tested: 1, the appearance of filter material: observe whether there is a jumper line, defect, puncture, black spot, joint, broken line, etc. 2, the mechanical properties of the filter material: testing the tensile strength, elongation at break of filter material, warp/weft direction of the load elongation and burst strength of filter bag is in line with the standard.
