测定方法 Test Measures

中位经：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，表面处理碳酸钙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：JIS-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 value of accumulative percentages of particle size distribution tested by NSKC-1A

centritugal photosedimentometer and as surface-treated calcium carbonate 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 cacldate the residue proportion

Whitenness:tested by DSBD-1digital whiteness meter

Oil absorption:titrated by linseed Oil until block -shape appears and then tested by JIS-K5101

Moisture:tested by the drying oven method。
