醚键 meaning in Chinese
ether linkage
Examples
- The results show that the gel time of the resol prepared in this paper is much longer than that of resol catalyzed with normal alkali such as ammonia and it is more stable when temperature is under 160 ; while temperature exceeds 160 , it cures very fast
结果表明，合成的酚醛树脂中有大量醚键，常温下它的凝胶时间很长，固化速度慢，温度大于160后，醚键分解产生甲醛，促进固化，凝胶时间迅速减小，固化很快。 - In this paper , a new class of concrete high performance water reducer ( hpwr ) was designed from chemical classification of high performance wra , working principle and unit structure model of poly - carboxylate series wra . the comb - like copolymer structure of hpwr was " carboxylic group - ether link - ester link " . the synthetic chemical materials was polyethylene glycil , acrylic acid and methyl - metacrylic acid ester
本文从高性能减水剂的化学结构、作用机理以及聚羧酸类减水剂的单元结构模型出发，设计出国内所没有的一类新型高性能减水剂? ? “羧酸?醚键?酯键”为单元结构模型的梳型分子结构的减水剂共聚物，并确定了以聚乙二醇( peg )系列、丙烯酸( aa ) 、甲基丙烯酸甲酯( mma )为合成该类减水剂的主要化学原料。 - The paper consists of the following parts : ( 1 ) synthesis of a novel resol with dibenzyl ether bond ; ( 2 ) preparation of the phenolic resin / layered silicates nanocomposites ( rplsn ) and investigating the melt intercalation and curing behavior ; ( 3 ) discussing mechanical properties and its related influence factor
本文分为三个部分：首先合成带苄基醚键的热固性酚醛树脂，然后制备粘土聚合物纳米复合材料讨论其熔融插层和剥离行为，最后讨论各种因素对力学性能的影响。一带苄基醚键的无氨热固性酚醛树脂的合成。
