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

Company Information
- 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: 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 do you pack the filter bags in the washing machine
- In order to prevent filtering or filter box breeding bacteria, it is recommended that users be taken apart.
- Q: How do you 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: Choose what aspects to consider when choosing a filter bag
- To choose his own dust filter bag, want to consider the effect of filter bag of gas temperature, moisture and chemical, particle size and dust concentration, filtration velocity, cleaning methods and other factors. The fabric and design of filter bags should be as efficient as possible, easy to remove and durable. Dust filter bag in the heart of the bag filter, commonly known as dust filter bag filter bag or filter, filter filter bag is a key part in bag filter operation process, usually cylindrical shape filter bag vertically hanging in dust collector. In the pulse and air box type pulse dust collector, dust is attached to the outer surface of the filter bag
- Q: Is there a filter bag for the washer?
- The cylinder washing machine does not have a filter bag similar to the wave wheel; But there are also filters in the washing machine. Current domestic cylinder washing machines have filters in the drain pump. The manual of the drum washing machine has a prompt to clear the filter regularly. There is dog hair on the clothes and can be washed in a washing machine. But be sure to clean up the pump when you're done.
- 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: What do you notice when the filter bag and dust collector are installed?
- The installation of the filter bag cage is the most careful in all installation and work carefully, so should last for installation, the installation, the bag must not delimit with sharp hard object collisions, hook, even minor scratches, also can make greatly reduces the life of the bag.
- Q: How about the filter bag of the washing machine
- One hand holds the middle position in the net and the other hand is pressed from the lower pressure, which can be removed and must be careful not to break the card. Note: to prevent filtering or filter box breeding bacteria, it is recommended that users be taken apart.
- Q: How to maintain the filter bag?
- The repair cost of cloth bag is always the largest proportion in the repair of cloth bag dust collector. So it should be noted that during the adjustment of dust exhaust gas flow, when the flow rate is larger, should increase the flow of the automatic control system, thus ensuring filter can work under stable volume. The inhomogeneity of the intake can cause damage to a certain part of the cloth bag and cause the cloth to perforate. The inlet should be installed in the inlet duct or replaced with a more worn cloth bag. In particular, notice the distance between the cloth bag and the keel. The keel is often broken by a burr when welding. In the other case, because of the long exposure to high temperature exhaust, it is easy to break through the temperature of the exhaust. Change the cloth bag in time.
