prepolymerization meaning in Chinese
预聚合
Examples
- Polybutadienes, epoxy resins, and similar polymers may be used while they are in the viscous or liquid state of prepolymerization .
聚丁二烯，环氧树脂及类似聚合物在粘性状或液体预聚态都是可用的。 - Study on modification of water based polymer - isocyanate adhesive by prepolymerization
异氰酸酯胶粘剂的改性研究 - The results indicated : the mechanical properties of pu prepared by added eg in a two - step process in prepolymerization technology were better than that of one - step process , its tg shifted 6 towards high temperatures ; the tan peak of pu material at low temperature disappeared through decompress boiling distilling technology
结果表明，采用预聚体工艺并且分步加入eg所制备的聚氨酯弹性体具有较好的力学性能，玻璃化温度向高温方向偏移了6 ；采用减压共沸蒸馏工艺制备的聚氨酯材料在低温区的tan峰消失。 - At last , several suggestions are proposed : to design a new formula without public hazards ; to preform a toxicity eliminating design for existing toxic slurries ; to give the measures of implementing green chemical grouting including the respects of technique , equipment and environmental protection ; and to point several kinds of grouting matinals to be unsuitably used or carefully used , and to quick improve the techniques of prepolymerization and post - processing
提出了按无公害要求设计新配方，对有毒害浆材进行去毒害改性设计，并通过采取工艺改造、设备更新、安全防护等措施来实现绿色化学灌浆的诸多办法，并对不提倡用、应慎用和应改进预聚及后处理工艺的浆材品种提出了改进建议。
