气垫薄膜真空处理是一种用气垫薄膜和可调式真空泵进行机械脱水,从而获得较低水灰比的优质混凝土的生产工艺。此工艺已在预制构件生产中得到应用,并逐步显示出了它的优越性。预制构件生产技术的发展要求:缩短热养护过程中的静停期,实现流水作业,提高劳动生产率;缩短养护周期,加速模板或台座的周转,减少工位和生产场地,节约生产过程中的能耗;改善产品质量,提高构件的合格率和优质率;节约原材料,降低生产成
The air-cushion film vacuum treatment is a production process of mechanical dewatering using a cushion film and an adjustable vacuum pump to obtain a high-quality concrete with a lower water-cement ratio. This process has been applied in the production of prefabricated components and has gradually demonstrated its superiority. The requirements for the development of production technology of prefabricated components: Shorten the static stop period in the heat conservation process, realize flow operations, increase labor productivity, shorten the maintenance cycle, accelerate the turnover of the formwork or pedestal, reduce the number of work stations and production sites, and save energy in the production process. Consumption; Improve product quality, improve the qualification rate and quality rate of components; Save raw materials and reduce production
