How to choose the material of industrial meltblown filter element?

Since meltblown filter elements are generally used in the field of liquid filtration, various factors should be considered when selecting meltblown filter materials.

Polypropylene PP has good solvent resistance and is insoluble in various organic solvents and oil and water; And polypropylene is a material with good acid and alkali resistance, no corrosion, no rot, and can withstand high temperatures, and its best is relatively cheap.

To sum up the above advantages, polypropylene PP material was selected in the experimental process of meltblown core building. In this experiment, polypropylene material from Shanghai Petrochemical Co., Ltd. was used, the grade was Y2600T, the melt flow index was MIA, the ash content, and the isometric index was 90%%.

The melt-blown spinning molding of polymers is usually carried out in the state of melt, and the flow characteristics of the polymer logistics body can be determined and studied and the flow curve can be drawn to understand the dependence of its apparent viscosity on the shear rate (r), the relationship between the structure and the temperature (t), etc., and the engineering data such as the dryness of the spinning stock solution, the shear stress in the flow, and the shear rate can be obtained, which has important guiding significance for the design of the best mechanical equipment and the formulation of reasonable process conditions. In this experiment, the following properties of polymers were analyzed.

This kind of problem is impossible, it is recommended to find a regular manufacturer.

The common melt-blown filter element is made of PP (polypropylene), compared with the stainless steel filter element, the melt-blown filter element is characterized by being cheaper, but it needs to be replaced frequently.

Polyester, polyamide, polyethylene, PTFE, polystyrene, PBT, EMA, EVA, etc.

The meltblown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles, which is heated and melted, spinnered, pulled and formed. If the raw material is mainly polypropylene. It can be called PP meltblown filter element.

It is used not only in large quantities for water purification. It also has excellent chemical compatibility and is suitable for the filtration of strong acids, alkalis and organic solvents. Strong dirt-holding capacity, long service life and low cost.

Performance characteristics: Clause.

1. Polypropylene is used as raw material and winding with continuous polypropylene long fibers produced by meltblown process.

Clause. 2. High filtration precision, large flow rate, uniform structure, large dirt holding capacity and long service life.

Clause. 3. It has good chemical compatibility, no additives, and the fiber is not easy to fall off.

Clause. Fourth, it is widely used.

High dirt retention capacity:

The effect of capturing particles according to density is truly realized in the deep layer of the filter element, so that the effectiveness of the filter element can be fully exerted; Higher dirt retention means longer service life and lower replacement frequency and cost savings. The surface density of the filter element is low, and the density gradually increases from the surface to the center of the filter element; There are no surface blind spots that would reduce filter flow rates and increase the frequency of changeovers.

Pure polypropylene construction:

high-temperature bonded fibers; Does not contain humectants, antistatic agents and binders; Broad chemical tolerance; Easy to dispose of after incineration into ash; Meets FDA requirements for the food and beverage industry; No leachables and no leachables are generated.

Endotoxin: The water extract of the filter column was tested by LAL, and the endotoxin content was lower.

In addition, you can also take a look at the double filter element that is replacing the meltblown filter element, and compare the various properties to compare the effect and use cost.

The material of the PP meltblown filter element is PP, and the quality inspection is compared, in addition, it can be compared with the metal filter element to see the effect and use cost.

PP meltblown filter element is a tubular filter element made of polypropylene particles, heated and melted, spinnereted, traction and accepted forming, which is suitable for the filtration of strong acids, strong alkalis and organic solvents, with strong dirt-holding capacity and long service life.

The commonly used materials for PP meltblown filter elements are as follows:

1. Paper filter element.

2. Chemical fiber filter element: glass fiber metal fiber sintered felt polypropylene fiber, polyester fiber 3, mesh filter element: stainless steel mesh.

4. Linear gap filter element.

Wuhu Yongjie Filter Material was established in Wuhu County, Wuhu City, Anhui Province on October 27, 2009, and its main products are: PP filter element, pleated filter element, activated carbon filter element, security filter element, large flow filter element and PP meltblown filter element.

Japanese JNC filter element has the characteristics of large flow rate, long life, high pressure resistance and stable filtration accuracy. It's also cheaper.

Henan Tianyu brand is OK, military enterprises.

Polypropylene is used as raw material, and the depth filter element with a certain pore size gradient is formed by heating and molten spinneret traction, and the whole is produced at one time. The outer sparse and internal dense structure can evenly intercept pollutants of different sizes in the inner and outer layers of the filter element. It is often used for the pre-filtration of liquids.

Strong dirt-holding capacity, long service life and low cost. In addition, the meltblown filter cartridge** is advantageous and of high quality. National Filtration Environmental Protection is a professional meltblown filter manufacturer, product model diversity, the materials used have been scientifically verified, and can play an effective role in filtration.

The polypropylene pleated filter element uses polypropylene composite membrane (polypropylene) as the main filter material, which is an advanced fixed depth filter element with a nominal filtration accuracy ranging from 60 m. The filter membrane is not affected by the fluctuation of feed pressure, which affects the filtration accuracy. Its unique advantages such as low pressure difference, high flux, good filtration accuracy and low economic cost are deeply loved by the majority of users.
