| 中文摘要: |
| 研究3种天然橡胶（NR）[胶清胶（SCR-G）、全乳胶（SCR-WF）、10#子午线轮胎胶（SCR-RT10）]性能的差异。结果表明：SCR-G的灰分、挥发分和氮含量较大，杂质含量和塑性保持率较小，物理性能较好，且价格较低,适用于发泡橡胶制品和鞋底；SCR-WF的灰分、杂质和氮含量都较小，加工安全性能较好，物理性能较差，适用于输送带、密封圈和胶鞋；SCR-RT10的杂质含量较大，氮含量较小，加工安全性能较差，适用于轮胎和输送带等。 |
| 英文摘要: |
| The difference in the properties among three kinds of natural rubber（SCR-G，SCR-WF and SCR-RT10） was studied in this paper. The results showed that the ash content，volatile content and nitrogen content of SCR-G were high，its impurity content and plasticity retention index were low，it possessed good physical property and low price，and it was suitable for foam rubber products and soles. In contrast，the ash content，impurity content and nitrogen content of SCR-WF were low，it had good processing safety property but inferior physical property，and it was suitable for conveyor belts，seals and rubber shoes. In addition，the impurity content of SCR-RT10 was high，but the nitrogen content was low，the processing safety property was poor，and it was suitable for tires and conveyor belts. |
