多孔質金属ディスク
多孔質金属ディスク
The porous metal disc adopts advanced powder metallurgy sintering process to sinter 316L stainless steel powder at high temperature into a disc structure with uniform interconnected pores. The sintered metal disc has both the mechanical strength and precision filtration performance of metal materials, and can be used in a variety of process scenarios such as gas-liquid distribution, gas diffusion, microfiltration and pre-membrane protection. With its stability and reproducible cleaning characteristics, LiandaFiltration’s porous metal discs are widely used in the chemical, petroleum, pharmaceutical, environmental protection and food and beverage industries.

製品の特徴と利点
Uniform pore distribution
Each stainless steel porous disc is precisely sintered to form interconnected channels to ensure uniform fluid penetration and eliminate dead corners and bias flow.
High mechanical strength
Metal sintered structures are more resistant to impact, pressure and vibration than fiber membranes or plastic filter membranes, and are particularly suitable for metal mesh disc applications under harsh working conditions.
Wide working condition compatibility
Supports operation at -20-550 ℃ and normal pressure to 10 bar, resistant to acid, alkali and organic solvent corrosion, suitable for chemical reaction gas, steam, pickling wastewater and other media.
Low pressure drop and high flux
Wide pores and large effective filtration area control the pressure drop within the range of 20-100 Pa while maintaining excellent flux.
Repeated cleaning and regeneration
Supports high-pressure water flushing, chemical immersion or ultrasonic cleaning, performance recovery after cleaning, long service life, and greatly reduced replacement costs

よくあるご質問
Depending on the maximum particle size in the medium and the permissible pressure drop, 1–5 µm is suitable for fine filtration and 10–20 µm is used for gas distribution and spraying. LiandaFiltration can provide selection support and testing services.
It is recommended to use reverse high-pressure water flushing combined with chemical immersion or ultrasonic cleaning on a regular basis; for highly contaminated conditions, cleaning should be done once a month or after every 500 hours of operation.
In conventional chemical media, the service life can reach 3-5 years; depending on the working conditions and cleaning and maintenance, the replacement cycle can be flexibly extended or shortened.
LiandaFiltration supports customization of porous metal discs in terms of outer diameter, thickness, porosity, and special alloys such as Inconel and Hastelloy to meet more demanding process requirements.
