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

Company Information
- 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: 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 many types of filters are in the filter bag?
- Flat: the filter bag is flat, including rectangle and trapezoid, which is represented by the perimeter of the length.
- Q: How to choose a liquid filter bag
- Filter bag precision options: This is the most troubling question. For example, to remove visible particles, use a 20 or 25 micron filter bag. To remove the cloud from the liquid, use a 1 or 5 micron filter bag. To filter out the smallest bacteria, you need a 0.2 micron filter bag. The problem is that there are two types of filter units: absolute accuracy/nominal accuracy.
- Q: What is the correct way to 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: Which is the liquid filter bag?
- Rising is good.Well, it's good for Fred.I hope my answer will help you.
- Q: What is the effect of a dust filter bag?
- The second is that the filter bag has gravitational sedimentation. Thermal motion; The role of inertial forces; Sieve filters and so on
- 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: How to buy the paint filter bag in the car painting
- Haha, it's easier for me. I want to answer the question from all the processes in the painting workshop. Pre-treatment, electrophoresis line need the following filtering material: 1, the filter bag (need) in the tub filter 2, phosphate slag filter bag/belt (need to use phosphate slag filtration system) 3, biofilm generated electrophoresis (ultra filtration membrane filtrate need) coating,... Core masterbatch 1 degreasing powder, powder formula: degreasing powder core masterbatch + base (either soda ash, sodium bicarbonate, sodium silicate) 2, alkaline water recipe: degreasing powder core super universal masterbatch + surfactant + + water + preservatives + essence 3 wire drawing powder, water-based neutral formula: super nanometer emulsifier + super oil emulsifier, wire drawing powder + water + preservatives, fragrance 4, preparation of alkaline...
- Q: How do garbage bags in washing machines have no garbage
- Check the wheel. If it's broken, you should ask the professional to fix it.
