Title (EN) GREASE COMPOSITION
(FR) COMPOSITION DE GRAISSE
(JA) グリース組成物
Abstract:
(EN) A grease composition containing a base oil (A), a urea-based thickener (B), an antioxidant (C), and a rust inhibitor (D), wherein the maximum frequency peak in the particle size distribution curve on a volume basis obtained by measuring the light scattering particle size of particles containing the urea-based thickener (B) in the grease composition satisfies requirements (I) and (II). ∙Requirement (I): the particle diameter at the maximum frequency peak is 1.0 μm or less. ∙Requirement (II): the half width of the peak is 1.0 μm or less.
(FR) L'invention concerne une composition de graisse contenant une huile de base (A), un épaississant à base d'urée (B), un antioxydant (C) et un antirouille (D), le pic de fréquence maximale dans la courbe de distribution de taille de particule sur une base de volume obtenu par mesure de la taille de particule de diffusion de lumière de particules contenant l'épaississant à base d'urée (B) dans la composition de graisse satisfaisant les exigences (I) et (II). ∙ Exigence (I) : le diamètre de particule au pic de fréquence maximale est inférieur ou égal à 1,0 µm. ∙ Exigence (II) : la demi-largeur du pic est inférieure ou égale à 1,0 µm.
(JA) 基油(A)、ウレア系増ちょう剤(B)、酸化防止剤(C)、及び防錆剤(D)を含有するグリース組成物であって、前記グリース組成物中のウレア系増ちょう剤(B)を含む粒子の光散乱粒子径測定による体積基準での粒子径分布曲線において、最大頻度となるピークが、下記要件(I)及び(II)を満たす、グリース組成物。 ・要件(I):前記ピークの最大頻度となる粒子径が1.0μm以下である。 ・要件(II):前記ピークの半値幅が1.0μm以下である。
