Title
(EN) MIXED ANTIBACTERIAL GLASS
(FR) verre mixte antibactérien
(JA) 混合抗菌性ガラス
Abstract
(EN)
A mixed antibacterial glass which is reduced in weight change during use and has excellent handleability and which has an excellent discoloration-preventing effect and imparts recognizability while maintaining a silver ion release amount in a given range. The mixed antibacterial glass comprises a colored antibacterial glass which produces an antibacterial effect based on the release of silver ions and a nonantibacterial glass, wherein the colored antibacterial glass has a maximum diameter (t1) of 3-30 mm and contains an inorganic colorant as an additive, the amount of the inorganic colorant added being 0.001-0.5 wt.% based on the whole.
(FR)
L'invention a pour objet un verre mixte antibactérien au poids réduit, qui connaît des modifications lorsqu'il est utilisé, présente une excellente maniabilité, d'excellentes propriétés anti-décoloration et permet une reconnaissabilité en maintenant la libération d'ions argent dans une plage donnée. Le verre mixte antibactérien comprend un verre antibactérien coloré, dont l'effet antibactérien est basé sur la libération d'ions argent, et un verre non-antibactérien, le verre antibactérien coloré présentant un diamètre maximum (t1) de 3 à 30 mm et contenant un colorant inorganique en guise d'additif, la quantité de colorant inorganique ajouté variant de 0,001 à 0,5 % en poids du total.
(JA)
使用時における重量変化が小さく、使い勝手に優れる一方、銀イオンの放出量を所定範囲に維持したままで、優れた変色防止効果や識別性が得られる混合抗菌性ガラスを提供する。 銀イオンを放出することによって抗菌効果を発揮する着色抗菌性ガラスと、非抗菌性ガラスと、を含む混合抗菌性ガラスであって、着色抗菌性ガラスの最大径(t1)を3~30mmの範囲内の値とし、かつ、配合成分として、無機系着色剤を含有するとともに、当該無機系着色剤の添加量を、全体量に対して、0.001~0.5重量%の範囲内の値とする。
