These different density layers can be achieved by changing polymer fiber size, rotation speed, air flow and so on.

This process can be automated with PLC control, ensuring constant and high-quality melt blown filters cartridges.

Concrete operations process as follows:

  1. Press the polymer fibers through an extruder and heated to their melting point.
  2. Blow out the molten polymer fibers through a nozzle with hot air.
  3. The fibers are collected on a rotating collection tube and form a porous matrix due to the high turbulent airflow.
  4. Fiber layers are built up to a predetermined thickness and thus form an effective “depth” filter.

Most of Filson melt blown filter cartridges are manufactured with polypropylene(PP).

Polypropylene(PP) is the most widely used polymer for meltblown technology.

Besides, a variety of different materials are used, including polyamide, polyester, and polyethylene.

Spun Bond Filter Cartridges VS Melt Blown Filter Cartridges

  1. Compared to spun filter cartridges, Filson melt blown filter cartridges requires a polymer with a relatively low melt viscosity.
  2. Because of using compressed hot air, Filson melt blown filter cartridges would consume more energy than the spun filter cartridges.
  3. Generally, meltblown nonwovens are more expensive than spun nonwovens, such as, the initial investment in spunbond technology is three to four times higher than that in meltblown technology.

String Wound Filter Cartridges VS Melt Blown Filter Cartridges

  1. Filson wound filter cartridges have a significantly larger effective surface area than melt blown filter cartridges, due to the overlapping characteristics of the wound wires.
  2. A core is required for string wound filter cartridge structural firmness. Filson melt blown filter cartridges do not require a core because the fiber is very firm itself. Certainly, a core can be added for additional structural strength or higher temperature resistance.
  3. Filson string wound water filter cartridges are exceptionally useful for surface water filtration, such as river water, wastewater and process  Filson melt blown filter cartridges are especially effective in spring water and city water, RO filtration and pharmaceutical processes.

Best Material for Melt Blown Filter

Melt blown filter cartridges are available in different materials, but the best among them is the polypropylene (PP) material.

Polypropylene

Polypropylene

It is one of the thermoplastic polymers that you will find in most of the filters we use frequently.

This is a product of chain growth polymerization originating from monomer propylene.

It is a member of the group polyolefins thus making it non-polar and partially crystalline.

It has properties similar to that of polythene, but it has higher resistance to heat and is slightly hard.

In most cases, it is white, mechanically rugged and is highly resistant to chemicals.

Chemical and Physical Properties

The aspects of polypropylene are similar to that of polyethylene especially when looking at electrical properties and solution behavior.

The properties of the polypropylene will depend on the molecular weight and the distribution of the molecular weight.

PP material

PP Material

Apart from that it also depends on its crystallinity, proportion and type of commoner and isotacticity.

Thermal properties of the material vary and will occur in a wide range.

The melting point will happen in a wide range usually a determination of “different scanning calorimetry chart”.

A perfect polypropylene has a melting point ranging between 160 degrees centigrade to 171 degrees Celsius.

It has a very wide thermal expansivity but is not as large as that of the polyethylene.

The chemical properties of polypropylene include:

  • Resistance to fats and almost every organic solvent at room temperature except for powerful oxidants.
  • It can dissolve in non-polar solvents such as tetralin, xylene, and decalin in elevated temperatures.
  • It is also chemically less resistant than PE because of the presence of the tertiary carbon atom.

The crystalline structure divides it into different types of polypropylene which include:

  • Isotactic Polypropylene that exists in various modifications differing by molecular arrangements of polymer chains. The adjustments fall under the alpha, beta and omega modifications as well as smectic forms.
  • Syndiotactic polypropylene is a late discovery of the polypropylene. You can only prepare this type of polypropylene by using a metallocene catalyst. It has a low melting point depending on the tacticity degree.
  • Atactic polypropylene which amorphous and the crystal structure is not defined. In simple terms, the polypropylene has no crystals making it soluble at moderate temperatures.

What is Melt Blown Technology

Melt blown technology is among the techniques you can use in making the filter cartridge.

In many cases, you will come across the name melt blowing technology which means the same thing.

It is the primary process by which manufacturers use to make the polypropylene melt blown filter cartridge.

It is a conventional method of fabrication of nanofibers and microfibers where polymer melts extrude through small nozzles.

Melt blown filter cartridge

Melt blown filter cartridge

The extrusion of the polymers is because of gas that blows at very high speed.

The fibers that deposit randomly form a “nonwoven sheet product” that you can apply in:

i. Filtration: -Porous melt blown fabrics are common and integral components infiltration of liquid as well as gaseous materials. The main applications are in the treatment of water, gas masks. Air conditioning among others.

ii. Sorbents: – Non-woven materials can retain lots of liquids that are several times heavier than their weights. The perfect example is the polypropylene which is capable of recollecting oil contaminants.

iii. Apparels: – They are the materials of choice in apparels even in harsh weather conditions mainly because of:

  • The thermal insulation properties
  • The ability to resist fluids
  • breathability

iv. Hygiene products: – The efficiency of the high sorption melt-blown nonwovens is common in sanitary napkins, diapers, and feminine hygiene products.

v. Systems of delivering drugs: – it is also responsible for the dispensation of fibers that control the delivery of drugs. It has a higher throughput rate, solvent-free process, and a more full surface area making it a promising technology.

The materials that you will produce through melt blown technology is similar to other nonwoven products.

Most manufacturers prefer to use this technology because:

  • It is a straightforward process.
  • It is highly specific, especially in productivity.
  • It is a process that does not involve the use of solvents.

Melt Blown Filter Manufacturing Process

The process of manufacturing melt blown filter cartridges is very simple depending on the kind of machines available.

Most manufacturers have the best devices which they use in manufacturing the melt blown filter cartridges.

Manufacturers use the process of melt blowing in the manufacture of the rounds.

The first step is the collection of all the raw materials you will need for the process.

Among the elements are the polypropylene resins and rollers among others.

In many cases, the rollers position within a rolling machine which rotates it at a considerable speed.

The rollers will, in turn, roll the polypropylene material around it as resins blow onto it.

The polypropylene will stick together as it rolls to a considerable diameter.

You will have to inspect the progress of the work as it is going to ensure that the process is going on well.

After that, the complete roll passes through cutting machines that will cut it into the length that you need.

You will then take every piece and weld the end cap on every side of the melt blown to complete the whole process.

Make sure you are putting on protective gear through the entire process of manufacturing the cartridges.

Type of melt blown filter cartridge

There are quite a number of applications where the melt blown filter cartridge works.

These applications, however, follow the same process involved in filtering the fluids.

In short, no matter the type or design of the cartridge, the process remains the same.

The fact that the polypropylene material is compact and in one piece making it resistant to media shedding and unloading.

The fixed pores structure and microscopic fibers provide integrity, efficiency and maximum retention of particles from the stream process.

They also have radial fibers responsible for distribution of gradient gradually loosening from inside towards the periphery.

The coarseness on the periphery provides enough absorption of dirt thus reducing the resistance of the filter.

The process also ensures that the material is rigid enough to take care of the process of filtration.

The layer on the inside has enough fine fibers which help in clogging the smaller particles and improves the precision of the filter.

The polypropylene resin makes the melt blown filter cartridge filter free of antistatic agents, surfactants, adhesives, and binders
