Description
i) 硫酸バリウム含有量が0.1mass%より大きく、かつ密度が 3.7g/cm3より高い、
ii) 硫酸バリウム含有量が0.2mass%より大きく、かつ密度が 3.6g/cm3より高い
i) 硫酸バリウム含有量が0.15mass%以上0.5mass%以下で、かつ密度が 3.8g/cm3以上4.0g/cm3以下、
ii) 硫酸バリウム含有量が0.3mass%以上0.5mass%以下で、かつ密度が 3.7g/cm3以上4.0g/cm3以下
1.4mmの篩いを用い、分散液を2回篩いを通して、水洗をおこない補強材を除去する。次いで例えば3000rpm×5分の遠心分離を施し、カーボンブラックを上澄みおよび上方沈殿から抽出し、下方沈殿から硫酸バリウムを抽出する。上記一連の操作で分離した硫酸バリウム、カーボンブラックを水洗乾燥した後にそれぞれの重量を秤量する。
