Title (EN) METHOD FOR PRODUCING SURFACE-TREATED ZINC OXIDE PARTICLE
(FR) MÉTHODE DE PRODUCTION DE PARTICULE D'OXYDE DE ZINC TRAITÉE EN SURFACE
(JA) 表面処理酸化亜鉛粒子の製造方法
Abstract:
(EN) This method for producing a surface-treated zinc oxide particle includes a first step for determining whether or not the specific surface area S (unit: m2/g) of the zinc oxide particle, the sodium content M (unit: mg/kg) of the zinc oxide particle, and the conductivity σ (unit: μS/cm) of a slurry produced by mixing 10 parts by mass of the zinc oxide particle and 90 parts by mass of pure water for 1 hour satisfy the following formula (1). S·M/σ2≥ 0.05···(1)
(FR) Cette méthode de production d'une particule d'oxyde de zinc traitée en surface comprend une première étape consistant à déterminer si oui ou non la surface spécifique S (unité: m2/g) de la particule d'oxyde de zinc, la teneur en sodium M (unité : mg/kg) de la particule d'oxyde de zinc, et la conductivité σ (unité : μS/cm) d'une suspension produite en mélangeant 10 parties en masse de la particule d'oxyde de zinc et 90 parties en masse d'eau pure pendant 1 heure satisfont la formule suivante (1). S·M/σ2≥ 0.05···(1)
(JA) 本発明の表面処理酸化亜鉛粒子の製造方法は、酸化亜鉛粒子の比表面積S(単位:m/g)と、前記酸化亜鉛粒子のナトリウム含有量M(単位:mg/kg)と、前記酸化亜鉛粒子10質量部と純水90質量部とを1時間混合して調製したスラリーの導電率σ(単位:μS/cm)と、が、下記式(1)を満たしているかを判定する第1の工程を含む。S・M/σ≧0.05・・・(1)
