electricity connects the stalk machine glues the knot repairs,Connect the strength to the calculation that glue, the material chooses to use, the function analyzes, the craft puts into practice etc.
对粘接强度的计算,材料选用,性能分析,工艺的实施等进行论述,根据胶粘技术与其他工艺相比较,具有成本低,易操作,时间短,效果好等特点,特别是在电厂检修中更能体现其经济价值和社会效益,具有极高的推广应用价值。
In this article,synthesized the PU adhesive with the polytetrahydrofuran and toluene diisocyanate,in the course of synthetic process a series of adhesive films were made only with changing R and keeping other relational conditions.
在合成过程中保持其它相关条件不变的情况下,仅改变R值(异氰酸指数)来制备系列胶膜,测试了R值与胶膜的拉伸强度、断裂伸长率、耐水性、预聚体邵氏硬度及粘度(常温)的关系,同时还运用了红外光谱法对所合成的PU胶粘剂进行了表征。
