測(cè)定方法 Test Measures

中位經(jīng)：以NSKC-1A離心式光透射粒度測(cè)定儀測(cè)得粒徑分布累計(jì)重量百分比之中間值，表面處理碳酸鈣之粒徑為處理前粒徑。

325目篩余：以濕式法將試樣篩分過(guò)濾，計(jì)算其殘留比例。

白度：以DSBD-1型數(shù)字白度儀測(cè)定之。

吸油量：JIS-K5101加入亞麻仁油滴至塊狀時(shí)測(cè)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。
