中文摘要：

对同一割龄6个品系的鲜胶乳,将其浓缩后比较各品系浓缩胶乳的性能,浓缩胶乳硫化胶膜的物理机械性能进行研究。结果表明：热研8-79鲜胶及浓乳的干胶和总固含量最高,热研88-13的钙镁含量最高,RRIM600的分子量最大,硫化胶膜物理机械性能最好。

英文摘要：

Among natural rubber latex of six strains from the same year,we concentrate the natural latex,then comparing strains of performance,and vulcanizate the concentrated rubber compare various strains of vulcanized rubber concentrated mechanical properties.Results showed that the hot research 8-79 have the highest dry rubber content and Total solid content by the natural latex and concentrated latex,hot research 88-13 have the highest content of calcium magnesium,hot research 8-79 have the highest impurity content.RRIM600 have the the maximum molecular weight,physical and mechanical properties of the best film.
