| 中文摘要: |
| 研究高性能烟胶片制备用天然胶乳的筛选。结果表明：云南西双版纳勐醒、临沧孟定及普洱江城3个天然橡胶核心产区生产的天然胶乳均适合用作高性能烟胶片的制备原料；江城GT1和江城600#两个品系天然胶乳制备烟胶片的拉伸强度均处于较高水平，非橡胶组分含量和相对分子质量分布与印度尼西亚烟胶片RSS#1相当，综合性能更好；5月和6月份采割的天然胶乳生产的烟胶片的塑性保持率更高，焦烧时间更长，加工稳定性更好。综合考量产地适应性、品系优越性及季节稳定性3个维度，宜选取普洱江城产区在5月至6月采割的江城GT1或江城600#品系天然胶乳作为制备高性能烟胶片的首选原料。 |
| 英文摘要: |
| Screening of natural rubber latex for high-performance smoked sheet production was studied.The results showed that natural rubber latex from three core production regions，including Lincang Mengding，Xishuangbanna Mengxing and Puer Jiangcheng in Yunnan were all suitable as raw materials for high-performance smoked sheet.Smoked sheet produced from Jiangcheng GT1 and Jiangcheng 600# natural rubber latex exhibited high tensile strength，with non-rubber component content and molecular weight distribution comparable to Indonesian smoked sheet RSS#1，demonstrating superior overall performance.Smoked sheet produced from natural rubber latex harvested in May and June showed higher plastic retention index，longer scorch time，enhanced processing stability.Considering adaptability to production regions，superior strain characteristics and seasonal stability，it was recommended to select natural rubber latex from the Puer Jiangcheng production area，specifically from the Jiangcheng GT1 or Jiangcheng 600# harvested between May and June，as the preferred raw material for high-performance smoked sheet production. |
