预湿 meaning in English
prewetting
Examples
- Building structure template parts and scaffold parts , buried foundry goods used under the railway crosstie , znsulator iron cap of suspending form series and ring flange
建筑用模板,脚手架配件,铁路预湿件,悬式绝缘子铁帽,铸铁法兰。 - The mwd value of this method was bigger than the routine methods one , and the mwd index of fw and slow wetting ( sw ) treatment were agreed significantly to the > 0 . 25mm size percentage given by wet sieving in the routine methods
团聚体快速湿润( fw ) 、慢速湿润( sw )和预湿后扰动( ws )三种处理之间存在显著差异。 fw处理与sw处理呈极显著相关关系,而与ws处理不相关。 - The result indicate that the lightweight aggregate with normal shape are easy to control than that with globular shape . the homogeneity of concrete can be improved by prewetting the ceramisite agitator , and should shorten vibrating time
研究结果表明,普通型陶粒混凝土较圆球型陶粒混凝土匀质性更容易控制;对吸水率较大的陶粒可以通过预湿来改善匀质性,另外应尽量缩短振动时间。 - At last , the mechanism of blasting - dust control by prewetting demolished buildings is analyzed , that is , liquid - bridging force helps dust - particles to come together and become another larger particles ; the quick descent of the larger particles makes the blasting - dust control come true
指出水预湿被爆体降尘法的机理是:尘粒间的液桥力促使润湿尘流中的尘拉变大,变大的尘杜迅速下降,从而实现降低爆尘目的。 - This paper deals with high fluid concrete in which high strength ceramsite made from shale was used as coarse aggregate . effects of cement content , water - cement ratio , sand percentage , mineral admixture , grading and pretreatment of lightweight aggregate on compressive strength and workability of high fluid structural lightweight aggregate concrete have been studied . the rules of water absorption of high strength lightweight aggregate under different pressure and effects on uniformity of high fluid structural lightweight aggregate concrete have been studied too
本文采用高强页岩陶粒,掺加高效减水剂配制大流动性结构轻集料混凝土,讨论了水泥用量、水灰比、砂率、矿物掺料及轻集料的级配和预湿方式对大流动性结构轻集料混凝土强度和工作性的影响;系统研究了高强陶粒在常压和压力下的吸水规律;研究了影响大流动性结构轻集料混凝土匀质性的因素,提出了解决大流动性结构轻集料混凝土分层离析的具体措施。
