光泽度有镜面光泽度、对比光泽度等,目前国际上通用的是镜面光泽度。镜面光泽度是一个心理物理量,它指的是在相同条件下,经测量表面反射后进入镜面反射方向上的规定孔径的光通量与标准镜面反射表面反射的光通量之比。根据标准板的材料,以70光泽单位为界线,可将镜面光泽度分成高、低二档,相应的标准板称为高光泽度标准板和低光泽度标准板。我们以氧化硅陶瓷为材料研制出了低光泽度标准板。本文介绍该板的技术要求及工艺方法。
Gloss has a mirror gloss, contrast gloss, etc., the current international common is the specular gloss. The specular gloss is a psychophysical quantity which refers to the ratio of the luminous flux of a given aperture in the specular direction of reflection measured by a measuring surface to the luminous flux reflected by a standard specularly reflecting surface under the same conditions. According to the standard plate material, with 70 gloss units as the boundary, the mirror gloss can be divided into high and low second gear, the corresponding standard board called the high gloss standard board and low gloss standard board. We have developed a low gloss standard board made of silicon oxide ceramic. This article describes the board’s technical requirements and process methods.
