加气混凝土坯体浇注后,必须达到比较合适的硬度(一般为0.5kg/cm~2)才能进行切割。坯体强度过大时增加切割阻力,切割钢丝易崩断;坯体强度过小,在切割时易发生摊塌或使成品粘连而造成废品或次品。为了适时掌握切割时机,通常用手感来控制坯体硬度,但很难准确掌握。为了能很好的掌握坯体硬度,我们学习中国科 After pouring the aerated concrete body, it must reach a suitable hardness (usually 0.5kg/cm~2) to cut. When the green body strength is too large, the cutting resistance is increased, and the cut steel wire is easily broken; the green body strength is too small, and when the cut is performed, it is easy to collapse or cause the finished product to stick and cause waste or defective products. In order to grasp the cutting timing in a timely manner, the hardness of the body is usually controlled by hand, but it is difficult to accurately grasp. In order to master the hardness of the blank, we learn Chinese
