一、Structural characteristics of ceramic raschig ring

Ceramic raschig ring filler is a ring-shaped ceramic filler with equal height diameters, common sizes ranging from 25mm to 75mm, and wall thicknesses ranging from 2.5mm to 9.5mm. Large sizes (>100mm) are usually filled with whole-stacking, while small sizes (<75mm) are filled with random stacking. The filler is made of high-quality high-aluminum and low-iron clay and other ceramic raw materials. Through mold forming and high-temperature sintering processes, it ensures its high mechanical strength and chemical stability. It has a high porosity, a large void ratio, a high flux, a small resistance, a large specific surface area, a high internal surface utilization, and a simple structure, which is easy to clean and replace.

二、Performance advantages of ceramic raschig ring

Corrosion resistance: It can resist corrosion of various acids, alkalis, salts and organic solvents except hydrofluoric acid and strong alkalis.

High temperature resistance: It can operate stably in an environment of -196℃ to 1600℃, and the long-term working temperature of some high-end products can reach 1350℃.

High mechanical strength: compressive strength ≥80MPa, some silicon nitride ceramic products can reach 150MPa, ensuring that they do not deform under high pressure conditions.

Mass transfer efficiency: Through surface roughness regulation (Ra=6.3-12.5μm) and porosity optimization (>95%), the adhesion of biofilm is increased by more than 30%, and the mass transfer efficiency is significantly better than traditional fillers.

Anti-shock performance: Under high-speed fluid impact, ceramic surface coating can reduce wear rate and extend service life.
