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:In what aspects is it convenient to choose the filter bag?
- The fabric design of dust filter bag should be designed to be efficient filtration, easy dust stripping and durable effect. Dust filter bag is one of the important parts in the precipitator, bag filter is generally according to the properties of dust, dust removal by way of the nature and filter according to the different filter filter bag, filter bag so select filter attention focus is also different. A filter bag that is suitable for price performance according to the requirement of operating condition. The gas temperature. Gas temperature below 130 ℃ selection filter filter bag at room temperature, the temperature between 130 ℃ to 260 ℃ high temperature dust filter bag. Gas humidity. Dusty gases according to the relative humidity is divided into three states: dry gas (relative humidity below 30%), the general condition (relative humidity between 30% - 80%) and high humidity (relative humidity above 80%) of gas. When the gas moisture is high, you should choose the laminated waterproof cloth bag. The chemical properties of gases. The chemical elements of acid, alkali, oxidizing agent and organic solvents are found in all kinds of furnace gases and chemical exhaust gases. In order to select the filter bag, the filter bag should be chosen according to the chemical composition in the flue gas.
- Q:Choose what aspects to consider when choosing a filter bag
- Dust and dust are collected in the outer surface of the filter, while the clean gas is filtered through the filter. The inside of the filter bag is used to support the filter bag to prevent the bag from collapsing, and it helps to clear and redistribute the dust cake.
- Q:What are the features and methods of using filter bags?
- The filter bag is a key part of the process of the bag, which is usually hung vertically in the dust collector. The fabric and design of filter bag should strive for efficient filtration, easy dust stripping and durable effect. In pulse and air box type pulse precipitators, dust is attached to the outer surface of the filter bag. Dust and dust are collected in the outer surface of the filter, while the clean gas is filtered through the filter. The inside of the filter bag is used to support the filter bag to prevent the bag from collapsing, and it helps to clear and redistribute the dust cake.
- Q:How is the filter material processed by the filter bag?
- The second is heat finalization to ensure the stability of the chemical fiber filter, to maintain the reliable work of the dust collector, and to deal with the heat finalization of the filter material. It is also that hot melt pressure processing can increase the density of the needle felt, make the surface pore smaller, the fuzz is hot, smooth and smooth
- 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:How to check the filter bag and the dust collector bag when the dust collector is installed?
- You say the bag and the bag cage visual inspection before installation needs, from experience observation, at the time of assembly is the detailed inspection, in principle, a bag and bag cage on the diameter is 2.5 mm clearance, need adjustment of clearance is too large. Be careful when you wear a cloth bag. Are you asking about this question, the bag leak check, The method is to apply fluorescent powder to the surface of the phosphor powder, and see if there is any leakage at run time.
- Q:How does the filter bag work?
- Mechanical vibration wave sootblower is often used in small single cartridge filter, it is the use of filter plate produced by the eccentric gear on shaking power to clear the ash, this action need downtime after operation.
- Q:Please tell me where the filter bags are sold in the washer.
- The filter bag is broken, the average border is good, and you can make it yourself: you can cut it up and cut it into a bag that is the size of the right size, so you can stick it to the border.
- 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:What are the textures of the liquid filter bag
- Nylon net has high strength, wear resistance, chemical resistance, water resistance, flexibility is good, because the wire diameter uniformity, smooth surface, so the ink through sex is also very good. It is not very stretchable by nylon. This kind of screen is in a period of time after the stretch net, the tension is reduced, make the screen plate is relaxed, the precision is reduced. Therefore, it is not suitable for the printed circuit board and so on.
