Alumina Ceramic Cylinder / Disk / Wafer
Basic Info
Model No.: MRT-34
Product Description
Alumina Ceramic Cylinder / Disk / Wafer
A treatment process of alumina ceramic wafers comprises the following steps of (1) washing with distilled water: washing ceramic wafers with 100% pure water, and drying; (2) washing with acetone: soaking the washed ceramic wafers in 70-80% acetone, and drying; (3) alkali washing: soaking the ceramic wafers washed with the acetone in 10-20% sodium carbonate solution, and drying. The treatment process of the alumina ceramic wafers has the beneficial effects of being large in hardness, excellent in wear resistance, light in weight, strong in surface adhesive force (10-20 times of that of the untreated ceramic wafers), and firm and durable after being combined with rubber through glue.
