摘要
经研究后,对生物凝固法进行试生产,对比研究了2种胶的6项性能,贮存时间对天然橡胶Po和PRI值的影响,对影响生物凝固液及胶乳凝固效果的因素进行了分析与讨论。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2个单位以上,2种胶的PRI值较接近。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。
The experiment on producing rubber latex by the bio-coagulation method was carried out after discussion. The six biological properties of the two kinds of rubber were compared, and the storage time that affect the Po and PRI of the natural rubber, the factors that influence the bio-solidi-fication liquid and the latex coagulation effect were analyzed and discussed. The results showed that six properties of the bio-solidification latex were fine, and its Po was two units higher than that of the formic coagulation latex, but the PRI of the two kinds of latex was similar. According to the the-oretical calculation, we knew that the direct cost using in the production of dry rubber by the bio-so-lidification method was cheaper for 41 -43.5 yuan/t than by the formic coagulation method.
