| 摘 要： | 依照标准GB/T 3516—2006,采用索氏抽提法测定不同形状、不同数目天然橡胶试样的丙酮抽出物,结果表明:试样表面积越大;径向尺寸越短,其质量分数值越高。长条形试样表面积较大;径向尺寸较短,又便于制取,其试样适合测定天然橡胶丙酮抽出物。

| Abstract: | According to GB/T 3516 -2006, acetone extractives of natural rubber of different shape and number were determined by Soxhlet extraction method. The results showed that the larger the specimen surface area was and the shorter its radial dimension was, the larger its mass fraction was. Strip shaped specimen was suitable for the determination. |
