我厂自一九五三年起,即根据建筑部门的需要,前后生产过八、九种不同规格的大小空心砖;并仿照苏联、波兰等国家的经验,试制过一些异型的楼板空心砖。由于经验不足,在生产中,尤其是在成型过程中遇到过不少的困难和问题,有些问题至今仍然没有得到完全解决。现仅将几年来实际的体会介绍出来,供大家参考。 Since 1953, our factory has produced eight or nine hollow bricks of different sizes according to the needs of the construction department. After imitating the experiences of countries such as the Soviet Union and Poland, we have experimented with some special-shaped floor hollow bricks. Due to lack of experience, many difficulties and problems have been encountered in production, especially in the molding process. Some problems have not yet been completely solved. Only a few years of actual experience will be introduced for your reference.
