Difference between Sintered Plate Filter Media and Bag Filter Media:
The external shape of the molded board features a wavy pattern resembling an accordion box. If expanded into a flat surface, it equates to a threefold increase in surface area. The internal structure of the wavy filter plate is divided into 17 cavities. This design, in addition to considering the strength of the components, is primarily driven by the requirements of gas dynamics to ensure efficiency during the pulse air backflushing cleaning process. The dust collector assembled with this material occupies only 1/2 to 1/3 of the space of a bag-type dust collector with the same filtering area. The overall structure is also correspondingly reduced, featuring space-saving characteristics and creating conditions for user factory design and reduction in total equipment cost.
Thermosetting Plate Model:

The common sintered plate can withstand temperatures up to: 70℃ (room temperature)
Special Performance Sintered Plates: Acid-resistant, anti-static, explosion-proof, oil and gas-resistant, etc.
In most cases, the dust concentration at the intake can reach 500g/m³, while the dust concentration in the exhaust can be controlled below 5mg/m³. In high-efficiency dust removal systems, the dust removal rate is high. Widely used in industries such as steel rolling, metallurgy, chemicals, flue gas, electronics, food, plastics, welding processing, and precious metal recycling.
Properties of Sintered Plates:
The sintered plate filter cores feature a rigid wavy porous structure, with a sintered plate thickness of approximately 4mm, forming uniform pores of about 30μm internally. Subsequently, a PTFE coating is applied through a special spray process into the gaps of the substrate surface, creating micro-pores of 2~3μm.
2. The independent cavity sealing design ensures that even if there is air leakage in the sintered plate filter, there will be no large-scale dust emission causing environmental pollution.
3. The unique wavy design of the plastic烧结 filter core increases the filtration area while reducing the occupied space.
4. High dust removal accuracy: Micron-sized filter pore, capable of removing most dust particles larger than 0.1um.
5. Large Filtering Area: The corrugated design of the filter surface offers 3 to 6 times the filtering area of a filter bag within the same volume.
6. Strong self-cleaning capability: The rigid structure allows the reverse吹气 to act more directly on the particulate matter adhered to the filter surface, without any buffer, ensuring thorough dust removal.
7. Hydrophobic and oleophobic: The sintered plate substrate is made of various high polymer materials with different densities, and the PTFE coating penetrates deep into the pores of the sintered plate substrate, forming a super-fine pore anti-adhesive structure, which exhibits hydrophobic and oleophobic properties.
8. Excellent resistance to acids and alkalis: The special resin material can withstand long-term high-temperature corrosion from strong acids and alkalis.
9. Constant pressure, stable resistance; as the wave-shaped sintered plate filter core captures dust through the surface resin coating, its smooth surface makes it extremely difficult for dust to penetrate or remain. Even if some extremely fine dust particles manage to enter the cavity, they are immediately blown away by the flow of the set pulse compressed air. Therefore, there is no clogging phenomenon in the sintered plate filter core matrix.
