制造的经验:龙口的规格决定于粘土收缩性的大小。胶性粘土制成的砖坯,干燥后收缩率大,沙性粘土制成的坯收缩率就小。因此在决定龙口规格时,必须研究所利用的粘土性能。我们制做龙口时。就掌握了这一特点。具体的作法是在它的里口(靠近泥缸部份)与外口(出坯口)的正确“梢度”。“梢度”大,外泥缸进入龙口的粘土就多,泥条向外运动的速
Manufacturing experience: Longkou specifications are determined by the shrinkage of the clay. The brick made from colloidal clay has a high shrinkage rate after drying, and the shrinkage rate of the sand made from sand clay is small. Therefore, when deciding on Longkou specifications, it is necessary to study the properties of the clay used. When we made Longkou. It has mastered this feature. The specific approach is to correct the “shooting” of its inner mouth (close to the mud cylinder) and outer mouth (opening mouth). “Double” is large, there are more clays in the outer mud tank into the Longkou, the speed of the mud moving outwards
