測定方法 Test Measures

中位徑：以NSKC-1A離心式光透射粒度測定儀測得粒徑分布累計(jì)重量百分比之中間值，表面處理硫酸鋇之粒徑為處理前粒徑。

325目篩余：以濕式法將試樣篩分過濾，計(jì)算其殘留比例。

白度：以DSBD-1型數(shù)字白度儀測定之。

吸油量：以J1S-K5101加入亞麻仁油滴至塊狀時測定。

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
