Abstract

A comparative study of rubber sheets obtained using formic, acetic, and smoke acid as coagulants is shown for latex obtained from native Amazonian trees and also from commercial cultivated trees. The evaluation of both processes of coagulation was carried out by spectroscopic and physical-chemical analysis, showing no differences in the rubber sheets obtained. This new method of rubber sheet preparation was introduced into Amazonian rainforest rubber tapper communities, which are actually producing in large scale. The physical-mechanical properties were similar among a large sheets made by different rubber tapper communities using this new method.

摘要

展示了一项对使用甲酸、乙酸和烟熏酸作为凝固剂获得的橡胶片的比较研究，该研究针对的是从亚马逊原生树木以及商业种植树木中获取的乳胶。通过光谱和物理化学分析对两种凝固过程进行了评估，结果表明所获得的橡胶片没有差异。这种制备橡胶片的新方法被引入到亚马逊雨林橡胶采集者社区，这些社区目前正在大规模生产。使用这种新方法由不同橡胶采集者社区制作的大片橡胶片，其物理机械性能相似。
