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.

Quality-determining parameters

  • Temperature

  • Reaction time

  • Cooling time

 

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

  • alternative in      support of scrim in accordance with DIN 54 345 part 1 and part 5

Q:Who has used a liquid filter bag? What is its feature?
The dimension stability is good, the fiberglass itself does not contract at the standard temperature Chemical etch is good, acid and alkali resistance.
Q:How about all the filters in the washing machine
Either use a silk sock instead of using it, or buy a new one after the sale.
Q:Is there a filter bag for the washer?
Platen washing machine also has a filter bag, it's in the washing machine at the bottom, maomao, hair will collect there, you will see that place on the ground in a washing machine has a small door, it is inside the filter bag.
Q:Why is the filter bag material PE a polyester, not a polyethylene
Polyester: the general name of a polymer compound that is condensed by diglycol or polyols and dibasic acid or polyacid. Include polyester resin, polyester fiber, polyester acid glue etc. Polyester, Polyethylene terephthalate (PET) belong to the high molecular compound. Consists of terephthalic acid (PTA) and ethylene glycol (EG) through polycondensation produce polyethylene terephthalate (PET), part of the PET and ultimately generated by underwater pelletizing. Purpose: fiber grade polyester chip is used to make polyester staple and polyester filament, which is the raw material for fiber and related products of polyester fiber. Polyester film and bottle, and other purposes at the same time, widely used in packaging industry, electronic appliances, medical and health care, construction, automotive and other fields, the packaging is one of the largest non polyester fiber application market, is also the fastest growth in PET. It can be said that the polyester slice is an important intermediate product that connects the petrochemicals and the products of several industries.
Q:In what aspects is it convenient to choose the filter bag?
First, it is important to understand the temperature of the smoke that is being processed. If the normal temperature of the filter is lower than the temperature of the flue gas, it is possible to cause the cloth bag to burn down and cause a large economic loss. So how do you select the filter by the smoke temperature? Filter material by using temperature is divided into: under normal temperature is below 130 ℃, the temperature filter material of 130 ~ 180 ℃, high temperature filter material of 180 ~ 280 ℃. It is known that the temperature of the flue gas and the temperature of the filter can be selected by the filter. The second step is to understand the composition of smoke: this includes the content of the dust, the proportion, the size of the particle size, the viscosity and the moisture content of the flue. The method of cleaning the dust dust, the method of reprocessing and the filter wind speed of the filter were obtained. Usually a large amount of dust and dust is sticky and light condition choose pulse bag filter, filtration speed most control over 1.2 m/min, the minority under 1 m/min. The third step is to understand the amount of smoke that needs to be processed: the amount of air that dust can be treated by the dust collector is usually the operating air volume and the system leakage coefficient (10% ~ 15%). The formula: S = Q / 60V gives the total filter area by the formula: S = Q / 60V. S: total filter area Q: system processing air volume V: filter wind speed.
Q:Do you use a filter bag when you cook bone porridge
Not good, because the filter bag breaks down after high heat, forming bad health. What's more, the market's filtering bags are not fully qualified.
Q:What materials are commonly used in liquid filtration bags?
Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5% Expanding filter cloth (bag), improving filter wind speed and filtration efficiency, reducing the volume of dust removal equipment
Q:How do you clean a filter bag with oil stains?
1, the oil pollution in the filter bag is required to remove the oil by hand. 2, USES the high frequency vibration, will enter the filter filter bag inside the wall of the larger dust particles removed, will not affect fiber entanglement of fastness, keep the filter bag is good, easy tear of dirt. 3, extract the bag samples, using the professional instrument laboratory detection filter filter bag oil composition, to adapt to washing raw materials, the maximum cleaning filter bag and without causing any damage to the filter bag. Select the appropriate chemical preparation to soak the filter bag, remove the grease stain from the filter pocket, and increase the ventilation performance of the filter bag. Choose the appropriate washing materials and strict proportion. Low temperature water cleaning, the water is uniform, the strength is moderate, no mechanical damage to the filter bag. Use 110 degrees Celsius to heat air to dry, keep the size stability of the filter bag, and the filter bag is not deformed after drying. Finally, repair the damaged filter bag. The cleaning bag is basically the same as the new filter bag.
Q:What are the characteristics of a liquid filter bag?
Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5%
Q:How can the washing machine's filter bag be clean?
Remove the bag and turn it over and rinse under the tap for a few minutes.
