Product Description
Alumina Al2o3 Porous Ceramic Disc for Vacuum Chuck is composed by the distributed evenly open pores which is
interconnected by shape likearch , when the fluid through these pores,the suspended matter, colloidal particles, organic
molecules are trapped, adsorbed inside the micropores,then track to achieve the purification and filtration homogenizing
effect.The porous ceramic has the advatage with high strength,wear resistance, high temperature, corrosion, pollution, porosity
distribution, long service life and easy to regenerate, which is particularly suitable for a variety of gas, liquid filtration and fluidized
process.
Main Application field:
- New and refurbished alumina porous ceramic chucks for Disco, K & S, Applied materials TSK, Micro Automation, Load Point, etc
dicing saws and grinders.
- 4", 6", 8," 12″are regular sizes, And pore size include 15um, 30um, 50um, 100um.
Materials are alumina (Color: white, light brown, dark brown, blue-gray).
- Custom size (like square, oval shape, or irregular shapes) is available for us.
Specifically tailored techniques include:
• Spraying
• Brushing
• Backwashing
• Oven firing
• Dilute acid cleaning
• Solvent cleaning plus steam
• Ultrasonic cleaning
