超细改性硫酸钡

主要技术指标Specific Ation

测定方法 Test Measures

中位径：以NSKC-1A离心式光透射粒度测定仪测得粒径分布累计重量百分比之中间值，表面处理硫酸钡之粒径为处理前粒径。

325目筛余：以湿式法将试样筛分过滤，计算其残留比例。

白度：以DSBD-1型数字白度仪测定之。

吸油量：以J1S-K5101加入亚麻仁油滴至块状时测定。

水份：烘箱干燥法

Average particle size:the middle of value accumulative percentages of particle size distribut -ion tested by NSKC-1A centrifugal photosedimentometer and as for surface-treated calciu cabonate it is referred to the pre-treated size

Specfic surface area:tested by NSKC-1A centrifugal photosedimentometer

Residue of 325 Mesh:sieve the wetted sample and calcldate the residue proportion

Whiteness:tested by DSBD-1digital whitenessmeter

Oil absorption:titrted by linseed Oil until block-shape appears and then tested by JIS-5101 Moisture:tested by drying oven method
