Comparison between PP filter element and stainless steel sintered mesh filter element
PP Filter (PP melt-blown filter)
1. Production principle and characteristics
PP melt-blown filter is a tubular filter made of non-toxic and odorless polypropylene particles, which are heated and melted, spun, drawn and accepted. The filter itself does not use any chemical adhesives, more in line with the requirements of health, safety and high quality.

4 Apply
PP meltblow filter is suitable for deep coarse filtration of high clean materials, and is usually used as a pre-filtration of precision filtration. Therefore, it is often used in the pre-filtration of various pure water systems, and the purification and filtration of boiler water.
Stainless steel sintered mesh filter element
1. Production process
Sintered mesh is made of stainless steel mesh or punching mesh, three layers, four layers or five layers and other layers in accordance with different structures stacked together by diffusion solid melting process and surface filtration mechanism vacuum sintering, pressure, rolling, the material is easy to form, processing and welding, convenient production, can be processed into round, shape, cone, ripple and other shapes of filter elements.
2. Technical parameters
1) Applicable temperature :-200 "C-480°C
2) Filtration accuracy :1u~200u(filtration for reference data, orders subject to inspection)
3) Standard material :SUS316L SUS304
4) Standard thickness :1.7mm(can be customized according to customer requirements)
5) standard: 500 mmx1000mm600mmx1200mm1000mmx1200mm (according to customer requirements)
3. Performance
1) Stable and uniform filtration: protected by the upper and lower layers of wire mesh, coupled with the diffusion of solid fusion sintering process, the filter hole is not easy to deform, and uniform filtration performance can be achieved for all filtration accuracy, suitable for continuous and automated process.
2) Good strength: supported by the strengthening layer and the supporting layer, with high mechanical strength and compressive strength.
3) Easy processing: suitable for cutting, bending, stamping, tensile welding and other processing technology, easy to use.
4) Wide selection range: 316L, 304, 321, etc
Stainless steel sintered mesh filter element
5) Corrosion resistance: due to the use of SUS316L, 304 material, so strong corrosion resistance, suitable for acid and alkali environment filtration.
6) Wide range of use environment: can be used for -200℃~600℃ temperature environment,
7) Easy to clean: Because the mesh shape is fixed, the pore size is uniform, the hole is smooth and simple, and the surface filter material is used, it is easy to clean (can be cleaned by countercurrent water, filtrate ultrasonic melting baking and other methods), can be used repeatedly, and has long life.

6) catalyst support grid;
7) The application of gas uniformity in the powder industry:
Comparison between PP filter element and stainless steel sintered mesh filter element
1. Stainless steel sintered mesh filter element has good backwashing performance, long replacement cycle, and PP filter element can not be recoiled regeneration, generally speaking, it needs to be replaced once every 3 months.
2. Stainless steel sintered mesh filter has large mechanical strength, good stability, and is not easy to deform, while PP melt-blown filter has insufficient rigidity and poor weather resistance, which has post-shrinkage phenomenon, easy to age, become brittle and easy to deform after demoulding.
3. The price of PP melt-blown filter element is relatively cheap compared with the price of stainless steel sintered mesh.
3. The price of PP melt-blown filter element is relatively cheap compared with the price of stainless steel sintered mesh.
4. Stainless steel sintered mesh is resistant to high temperature, can be used continuously in a high temperature environment of 550 "C, intermittent use in a high temperature environment of 800°C, the maximum working temperature of PP melt-blown filter element is 80 °C
5.PP melt-blown filter PH range is 1-14, resistant to certain acid and alkali, but for strong oxidation and corrosive liquids, stainless steel sintered mesh filter has certain advantages.
