前言 常规的凝固制度,鲜胶乳常常用水稀释并加入有机酸以降低PH值。新的加工方法省去稀释,并将疑块碎裂,锤磨以制成颗粒橡胶。乳胶也能由外来的细菌和发酵作用,将非橡胶物质分解产生酸,使胶乳在48小时内自然凝固。加入一些碳水化合物可使凝固时间减少至16小时,若再用一种阴离子表面活性剂,凝固时间还会更短。

Introduction Conventional coagulation systems, fresh latex are often diluted with water and organic acids are added to reduce the pH. The new processing method eliminates the need for dilution, and the suspect fragmentation, hammer mill to make particles of rubber. Latex also by foreign bacteria and fermentation, the non-rubber material decomposition of acid, the latex in 48 hours of natural coagulation. Adding some carbohydrates reduces the setting time to 16 hours, and with an anionic surfactant, the setting time is even shorter.
