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

Q:What kind of bag is used in the food industry
Food industry USES dust filter bag: general polyester can.I hope my answer will help you.
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 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:What about the filtering effect of the lubricating oil filter bag
With the development of the industry, the lubricating oil filter bag is widely used in various fields of industrial occasions, lubricating oil filter bag is one of the most critical steps in the process of the filter.
Q:What is the filter bag made of foam tea?
That you go to the big supermarket will have to sell, there are two kinds, one kind is spun yarn bags, such as gauze, one is made of paper, paper bags are cheap and convenient, spun yarn is used for many times, see what you need...
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:Whether the washing machine filter bag is damaged or not
Does not affect the normal use, but some things on the linter and debris can't be filtered out, find a best silk stockings cut to the size of the filter bag to installed can normal use.
Q:Is it better to dust the air with a filter or a filter?
If the gas contains more dust in the filter bag, if the filtration precision is higher the filter core is required. If the dust is high and the precision is high, the filter cartridge will be used before using the filter cartridge.
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: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.
