Porous ceramic disc: Pore Size 5-50 μm, Diameter 50-300 mm

Component Specifications

Definition

A precision-engineered ceramic component with controlled porosity, designed for filtration, gas/liquid diffusion, or uniform fluid distribution in junction systems. It features interconnected pores that allow selective passage of substances while maintaining structural integrity under pressure and temperature variations.

Working Principle

Operates through capillary action and pressure differentials across its porous structure, allowing fluids or gases to pass while trapping particulates or facilitating controlled diffusion. The uniform pore distribution ensures consistent flow rates and filtration efficiency.

Materials

High-purity alumina (Al₂O₃) or silicon carbide (SiC) ceramic, with porosity ranging from 20% to 50%, pore sizes from 0.1 to 100 microns, and sintering temperatures of 1400-1800°C.

Frequently Asked Questions

What are the main applications of porous ceramic discs in junctions?

Used for filtering contaminants from fluids, distributing gases/liquids evenly, and facilitating controlled diffusion processes in chemical, pharmaceutical, and food processing junctions.

How do I clean a clogged porous ceramic disc?

Use backflushing with compatible solvents, ultrasonic cleaning, or thermal regeneration at recommended temperatures. Avoid mechanical scrubbing to prevent pore damage.

What factors affect the lifespan of porous ceramic discs?

Operating temperature, chemical exposure, pressure cycling frequency, and particulate loading. Proper maintenance can extend service life to 2-5 years.
