99 alumina insulated porous ceramic strip

Q: In high-temperature corrosive environments, common insulation or filtering materials frequently fail, resulting in high equipment downtime and maintenance costs?
Answer: The 99 alumina insulated porous ceramic strip is made of high-purity alumina sintered at high temperatures, with a temperature resistance of over 1600 ℃. It maintains structural stability in strong acidic, alkaline, and oxidizing atmospheres, greatly extending the replacement cycle.
Q: It is difficult for materials on the market to balance the requirements of porous and breathable materials with sufficient strength to support the components?
Answer: We precisely regulate the porosity (20%~60%) and pore size distribution, ensuring excellent permeability while maintaining a bending strength of over 30MPa, fully capable of dual tasks of structural support and functional integration.
Q: Does the standard product size not match the equipment, resulting in a long customization cycle and high minimum order quantity?
Answer: With the support of flexible production technology, we provide full-size customization services: lengths ranging from 5mm to 1000mm, starting from small batches.

Why is 99 alumina insulated porous ceramic strip your preferred choice?

1. Material properties: high purity, resistant to extreme environments
   -99% alumina content: minimal impurities, excellent electrical insulation (volume resistivity>10 ¹⁴Ω· cm), low dielectric loss at high frequencies.
   -Open cell structure: three-dimensional interconnected pores, uniform breathability, low resistance; Closed cell can also be customized for buoyancy or insulation.
   -Thermal stability: Low coefficient of thermal expansion (7.2 × 10 ⁻⁶/℃), resistant to thermal shock without peeling off.
2. Application scenarios: From vacuum suction cups to high-temperature carriers
   -New energy equipment: The burning support strip of the lithium battery material calcination furnace isolates the potential difference and avoids metal pollution.
   -Semiconductor manufacturing: plasma shielding components inside the etching machine, resistant to fluorine based gas corrosion, maintaining chamber cleanliness.
   -Environmental protection chemical industry: The catalyst carrier of the exhaust gas catalytic combustion device has a large specific surface area and strong coating adhesion.
   -General Machinery: Non metallic vacuum suction cup strips for automated production lines that do not damage the surface of precision workpieces.
3. Flexible customization: Your drawings, our craftsmanship
   -Size: The width/thickness tolerance can be controlled within ± 0.1mm, and the straightness of the long strip is ≤ 0.2mm/300mm.
   -Hole type: circular, square, irregular hole, or through hole, blind hole, cross hole.
   -End: capable of processing threads, chamfers, grooves, and can be installed at the factory.

Real customer case:
A certain photovoltaic equipment manufacturer
Pain point: The electrode insulation strip in the monocrystalline silicon growth furnace, originally made of quartz material, evaporates impurities at high temperatures and needs to be replaced every month due to thermal shock cracking.
Solution: Replace with our company’s 99 alumina porous ceramic strip with a designed porosity of 25%, ensuring insulation resistance>100M Ω and releasing thermal stress through micropores.
Effect: Continuous operation for 36 months without failure, equipment comprehensive efficiency increased by 8%, and annual maintenance costs reduced by 170000 yuan.
A precision fixture company
Pain point: The mobile phone glass panel is transported using rubber suction cups, which are prone to leaving marks and not wear-resistant.
Solution: Customize porous alumina ceramic suction strips, finely grind the surface to Ra0.4, and use negative pressure to evenly adsorb.
Effect: The scratch scrap rate has been reduced from 2.3% to 0.1%, and the lifespan of the suction strip has been extended from 3 months to over 2 years.
