摘要
通过对不同贮存期,不同熟化时间加工的天然橡胶标准胶产品,进行塑性初值(P0)和塑性保持率(PRI)的跟踪检测,试验结果:贮存1年内的胶样,不同熟化时间P0、PRI值并无显著差异;贮存1年以上胶样,不同熟化时间对P0值有显著影响,但对PRI无显著影响;随贮存时间增加,P0、PRI值看不出明显变化。
Determination of plasticity original （Po） and plasticity retention index （PRI） of standard rubber at different storage and aging time was made. The results indicated that there was no obvious difference in Po and PRI for storaged rubber within one year, while it has effect on Po and no effect on PRI at different aging time for storaged rubber over one year.
