Zirconia ceramic porous fan-shaped sheet

Zirconia ceramic porous fan-shaped sheet is a functional ceramic component made by dry pressing and high-temperature sintering technology using high-performance nano zirconia powder. Its unique fan-shaped structure combined with uniformly distributed micrometer sized pores not only possesses the inherent high hardness, wear resistance, and corrosion resistance of zirconia ceramics, but also enables precise flow control, uniform distribution, and high-temperature medium filtration. This product is widely used in high-end manufacturing fields such as chemical catalysis, environmental dust removal, food and beverage machinery, and biomedicine.

FAQ: Frequently Asked Questions for Users
Q1: In high temperature or strong acid and alkali environments, ordinary metal filters frequently corrode and deform, resulting in extremely high maintenance costs. Can this product solve this problem?
A: Absolutely possible. Zirconia ceramic porous fan-shaped plates have strong chemical inertness, acid and alkali corrosion resistance, and high temperature resistance of up to 1000 ℃. They can completely replace metal components that are prone to failure in harsh environments, greatly extending the service life of equipment.
Q2: The uneven distribution of fluid in our equipment leads to low reaction efficiency. Can this fan-shaped plate improve the fluid dynamics characteristics?
A: Yes, it is. The fan-shaped structure itself has a guiding effect, combined with our precisely controllable porosity (20% -50%) and pore size, it can ensure that the fluid forms a uniform radial or axial distribution when passing through, effectively eliminating “dead corners” and improving reaction or filtration efficiency.
Q3: Is the product prone to clogging? Is it convenient to clean and regenerate?
A: Compared to traditional filter materials, our product has superior backwash regeneration performance. Due to the smooth surface and stable pore structure of zirconia, intercepted particles can be easily removed and restored to their original state by reverse airflow or liquid flushing, significantly reducing the frequency of shutdown cleaning.

Core advantages of the product
Excellent material properties: Yttrium stabilized zirconia (Y-TZP) is used, which has high fracture toughness, excellent thermal shock resistance, and is not easily brittle.
Precise pore structure: uniform pore distribution, stable air permeability and filtration accuracy, pore size can be controlled between 0.5 μ m and 100 μ m.
Fan shaped geometric design: The unique fan-shaped appearance facilitates circular arrangement or splicing in cylindrical equipment, maximizing effective working area and improving installation sealing.
Environmental protection and lifespan: As an inorganic material, it does not cause secondary pollution to the medium, and its service life is 5-10 times that of ordinary metals or porous plastics.

Customer Application Cases
Case 1: Renovation of Gas Distributor in a Large Petrochemical Enterprise
Pain point of demand: The original porous plate gas distribution in the catalytic cracking unit of this enterprise is uneven, which leads to unstable fluidized state of the catalyst and seriously affects the output efficiency. In addition, the metal distributor needs to be replaced every six months due to high-temperature sulfur corrosion.
Solution: We have designed a 45 ° fan-shaped zirconia ceramic porous sheet with an outer diameter of 300mm, an inner diameter of 100mm, and a thickness of 10mm. Change the original single hole plate structure to a circular distributor composed of 12 ceramic fan-shaped pieces spliced together, with a designed aperture of 50 μ m and an aperture rate controlled at 35%.
Final effect:
Efficiency improvement: The gas pressure drop is reduced by 15%, the temperature uniformity of the fluidized bed layer is improved, and the reaction conversion rate is increased by about 2.3%.
Extended lifespan: After 18 months of continuous operation, the fan blades were disassembled for inspection, and there was no corrosion, blockage, or fracture. The expected service life can reach more than 8 years, saving the enterprise huge downtime maintenance costs.
Case 2: A high-end environmental protection equipment manufacturer – precision aeration disc
Pain point of demand: When developing a new generation of sewage treatment equipment, customers need an aeration element that can generate micron sized uniform bubbles at the bottom, requiring aging resistance and small bubble diameter to improve oxygen transfer efficiency.
Solution: Using 10mm thick fan-shaped zirconia porous ceramic plates, the average pore size is precisely controlled at 15 μ m through optimized sintering process. The fan-shaped design allows it to perfectly fit the curved structure of the tank bottom.
Final effect: The diameter of the generated bubbles is reduced by 30% compared to traditional rubber film discs, and the gas content is significantly increased. Due to the inertness of zirconia, the problems of aging, blockage, and rupture of rubber membranes in wastewater have been completely solved, and equipment noise has also been significantly reduced.
