Fabricant d'anneaux en céramique & Supplier

Strong corrosion resistance: Resists acids, alcalis, organic solvents and high-temperature steam; suitable for pH 0–14.

Excellent high-temperature resistance: Max working temperature up to 1600°C (material dependent), no deformation or collapse.

High specific surface area: Porous structure with 30–60% porosity, boosting adsorption, catalysis and biofilm formation.

Long service life & low loss: Mohs hardness 8–9, compressive strength ≥50 MPa, reducing replacement cost.

Customizable production: Flexible customization in size, pore diameter, material and shape (round, honeycomb, special).

Chemical packing: Mass transfer & distribution in reaction towers, absorption towers.

Environmental water treatment: Biofilm carrier, sewage filtration, denitrification & dephosphorization media.

Catalyst support: SCR denitrification, VOCs treatment catalyst substrate.

Électronique: Insulation supports for high-temp sintering furnaces, semiconductor protection rings.

Energy equipment: Fuel cell electrolyte rings, gas turbine thermal barrier coating substrates.

Advanced manufacturing: Isostatic pressing + high-temperature sintering for uniform density and stable performance.

Strict quality control: Full inspection of pore distribution, compressive strength and corrosion resistance; pass rate ≥99.5%.

Fast delivery: Standard items in 3 days; custom orders 7–15 days; small-batch trials supported.

Professional support: Working condition analysis, installation guidance and failure diagnosis.
