Abstract
Description
3H2O→O3+6H++6e−
生成されたオゾンは水に溶解することができ、いわゆるオゾン水となる。オゾン水は、食品加工、衛生施設及び医療サービスなどの分野における滅菌に使用されている。オゾンは酸化によって滅菌を行い、有機物及び無機物の両方を抑制する。
寸法が50mm×15mmであり厚さが0.5mmである成長したダイヤモンドプレートを用意した。レーザ切断技術を使用して、端部が平坦であり幅が0.2mmであり開口の間の間隔が0.3mmである96個のストレートサイド形の細長い開口を、ダイヤモンドプレートの厚さ全体を貫通するように切り、このプレートの核生成表面から48mm×13mmの加工領域を得た。これらの細長い開口はダイヤモンドプレートの最も長い縁部に平行とした。これらの細長い開口の壁は約4°の角度の先細り形状とした。ダイヤモンドプレートの前面及び背面を基準にして測定した開口の縁部長さの差は非常に小さく、成長表面と比較して核生成表面の方がほんのわずかだけ大きかった。
実施例1で記載したものと同様の装置を用意した。
寸法が50mm×15mmであり厚さが0.5mmであるダイヤモンドプレートを用意した。レーザ切断技術を使用して、直径が0.5mmであり開口の間の最小の間隔が0.2mmである1470個の円形開口を、ダイヤモンドプレートの厚さ全体を貫通するように切り、48mm×13mmの加工領域を得た。これらの円形開口の壁はわずかに先細り形状とし、核生成表面より成長表面のところを狭くした。切られたダイヤモンドプレートの前面及び背面は同じ面積であり、ダイヤモンドプレートの前面及び背面を基準にして測定した縁部長さは同一であった。
