加气混凝土进行切割时,必须使坯体具有适宜的硬度。过硬了,阻力大难切,钢丝容易崩断;过软了,坯体容易倒塌,制品容易粘连。一般地,有用插杆、用手指压的方法来感觉坯体软硬程度,也有用线锤下落测定锥孔直径大小等方法来掌握。前者要具有比较丰富的操作经验;后者的落距控制不准,锤孔容易歪斜,测读误差较大。我们参
When aerated concrete is cut, the blank must have a suitable hardness. Hard, difficult to cut, the wire is easy to break; too soft, the body is easy to collapse, the product is easy to stick. In general, the degree of softness and hardness of a green body can be sensed by a method of pressing a finger with a plunger, and it can also be grasped by measuring the diameter of a tapered hole using a drop of a line hammer. The former must have a relatively rich operating experience; the latter’s fall distance control is inaccurate, the hammer hole is easily skewed, and the reading error is large. We are
