终凝时间 meaning in Chinese
final setting time
final-setting time
time of final setting
time of initial setting
Examples
- Final setting time
终凝时间 - Setting time of gypsum plaster is very short , usually only 6 ~ 30 min , and operation time is only 5 - 10 min , which cannot satisfy the practical plastering and construction of gypsum - based material
半水石膏凝结硬化很快，其初终凝时间为6 30分钟，可操作时间只有5 10分钟，往往不能满足石膏基材料的成型与施工的需要。 - The study results indicated that , arranged in the order of magnitude , the degrees of the effects on the cementing strengths of the two interfaces were the system , emulsion , main emulsifier , fluid loss control agent and white oil respectively ; the cementing strength would be doubled and redoubled after being cleaned by preflush , especially by the system , emulsion and fluid loss control agent ; and , along with the increase in the mix slurry ratio , the initial and final set times of slurry would be obviously lengthened and the compressive strength of bond cement would be remarkably reduced or the slurry wouldn ' t be even set
研究表明：对两界面胶结强度的影响由大到小依次是体系、乳状液、主乳化剂、降滤失剂、白油；前置液清洗后，胶结强度成倍提高，尤其对体系、乳状液和降滤失剂清洗效果最佳；随混浆比的增大，水泥浆初凝和终凝时间明显延长，水泥石抗压强度明显下降，甚至不凝。 - In order to study the direct relation between oil - base drilling fluid performance and cement job quality , a new developed evaluation method ( artificial core method ) was adopted ; the effects of the oil - base drilling fluid system and its main components on the shear cementing strengths of the first and second interfaces in cementing operation were investigated ; and those of the different mix slurry ratios on the gel strength , initial set time , final set time of slurry and the compressive strength of bond cement were examined too
摘要为了研究油基钻井液性能和固井质量之间的直接关系，采用新建立的评价方法人工岩心法，考察了油基钻井液体系及其主要组分对固井作业中第一、第二界面剪切胶结强度的影响规律，以及不同混浆比例下对水泥浆胶凝强度、初凝时间、终凝时间和水泥石抗压强度的影响规律。
