如果新成型的混凝土制品通过真空吸盘可以得到较高的结构强度,并可立即脱模;运送和堆放,那么真空作业就能发挥出较好的效果。 采用真空作业时,重要的是使真空吸盘紧贴混凝土拌和物表面并不断移动,从而进行吸水,同时使混凝土密实。为此,研制了带柔性真空腔的真空 If the newly formed concrete product can get higher structural strength through the vacuum suction cup and can be immediately demoulded; transport and stacking, then the vacuum operation can achieve better results. When working in a vacuum, it is important that the vacuum cups are kept in close contact with the surface of the concrete mix and are constantly moving to absorb water while densifying the concrete. For this purpose, a vacuum with a flexible vacuum chamber has been developed.
