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:Do you use a filter bag when you cook bone porridge
- Yes, but it's not the same. I'll tell you what I do (but it's a long time). 1, wash the bones and blanch the blood water with boiling water Prepare, ginger, spring Onions, etc Wash rice, rinse with cold water, and set aside for use
- Q:Liquid filter bags should be aware of those items when installing
- Make sure the edge of the filter is cleared. Check the arcs and edges of the tennis basket. The upper edge of the net must be flat on the surface of the filter. If there are no nets or nets, there will be a filter failure. To install a new filter bag, the filter bag must be inserted into the net, and the bag sealing ring must be placed in the seal slot correctly.
- Q:How do you check if the filter bag contains phosphors
- In daily life, there are many opportunities for exposure to fluorescent agents. As long as no more than a certain standard (this method can only detect whether contain fluorescent agent, can't check out whether overweight), will bring many benefits to our lives. If too much contact with it can be harmful to the human body.
- Q:How do you check the filter material of the filter bag?
- Special features: the properties of heat resistance, abrasion resistance, flame retardant, antistatic properties, corrosion resistance and hydrophobic properties. Membrane filter: check the membrane strength.
- Q:What materials are commonly used in liquid filtration bags?
- 1, good heat resistance, can be used under 280 ℃ for a long time Dust is easy to peel off The dimension stability is good, the fiberglass itself does not contract at the standard temperature
- 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.
- 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 is the filter material processed by the filter bag?
- The treatment of precoating and surface coating can be very good to remove dust dust from the cloth bag and the filter material is very good to go out, greatly improve its performance.
- 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.
- Q:What is the filter bag for the washing machine?
- We always see something fluffy in our clothes when we wear clothes, and the washing machine filters the stuff!
