METHOD FOR PRODUCING SURFACE-TREATED ZINC OXIDE PARTICLE
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 pr...

Summary: | 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)
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).
