生物凝固法天然橡胶试生产的质量因素分析

Factors Influencing the Quality of Natural Rubber Produced Experimentally with Bio-coagulation

对生物凝固法进行试生产,对比研究2种胶的6项性能,贮存时间对天然橡胶Po和PRI值的影响,并对影响生物凝固液及胶乳凝固效果的因素进行分析与讨论。结果表明:生物凝固胶的6项性能较好,生物凝固胶的Po值比甲酸凝固胶的Po值高,两种胶的PRI值较相似。从理论计算可看出,生物凝固直接费用比甲酸凝固直接费用每吨干胶可节约41～43.5元。

We took a trial rubber production by the method of bio-coagulation. Comparing six performances from two kinds of the rubber. We find that storage periods will affect the Po and PRI of the rubber. We also analyze and discuss the reason of affecting the bio-coagulation liquid and latex solidification. The result shows that six performances of bio-coagulation are good. Its Po is higher than the Po of formic acid. And the PRI of the two kinds of the rubber is similar. So, by the theoretical calculation, the charge of the bio-coagulation is cheaper with 41 --43.5 yuan per ton than that of the formic acid
