Title (EN) METHOD FOR RECYCLING ABRASIVE AGENT FROM USED CERIUM OXIDE GLASS ABRASIVE AGENT CONTAINING FLOCCULATING AGENT
(FR) PROCÉDÉ DE RECYCLAGE D'UN AGENT ABRASIF À PARTIR D'UN AGENT D'ABRASION DU VERRE D'OXYDE DE CÉRIUM UTILISÉ CONTENANT UN AGENT FLOCULANT
(JA) 凝集剤を含む使用済み酸化セリウム系ガラス研磨剤からの研磨剤のリサイクル方法
Abstract: front page image
(EN)Provided is a method that easily recycles an abrasive agent having an abrasive performance equivalent to a pre-use new abrasive agent, and that has a high rate of elimination of silicon components and aluminum components from a used cerium oxide glass abrasive agent containing a flocculating agent. The method for recycling the abrasive agent from a used cerium oxide glass abrasive agent containing a flocculating agent includes a step for adjusting the pH of a slurry of the used cerium oxide glass abrasive agent containing a flocculating agent into the range of 10.0-14.0, and then adjusting the pH of the slurry into the range of 1.0-3.0.
(FR)L'invention concerne un procédé qui recycle aisément un agent abrasif ayant une performance abrasive équivalente à un nouvel agent abrasif avant utilisation et qui a une vitesse élevée d'élimination de constituants silicium et de constituants aluminium à partir d'un agent d'abrasion du verre d'oxyde de cérium utilisé contenant un agent floculant. Le procédé de recyclage de l'agent abrasif à partir d'un agent d'abrasion du verre d'oxyde de cérium utilisé contenant un agent floculant comprend une étape consistant à ajuster le pH d'une bouillie de l'agent d'abrasion du verre d'oxyde de cérium utilisé contenant un agent floculant dans la plage de 10,0-14,0, puis à ajuster le pH de la bouillie dans la plage de 1,0-3,0.
(JA) 凝集剤を含む使用済み酸化セリウム系ガラス研磨剤から、珪素成分やアルミニウム成分の除去率が高く、使用前の新品の研磨剤と同等の研磨性能を有する研磨剤を簡便にリサイクルする方法を提供すること。 凝集剤を含む使用済み酸化セリウム系ガラス研磨剤からの研磨剤のリサイクル方法であって、凝集剤を含む使用済み酸化セリウム系ガラス研磨剤のスラリーのpHを10.0~14.0の範囲に調整する工程、その後当該スラリーのpHを1.0~3.0の範囲に調整すること含む方法。
