前言 菱苦土原料在我国建筑工业上,已开始广泛的使用了,从许多单位的使用结果证明,菱苦土和锯末掺合在一起,用卤水加以调拌,可以制成木材代用品,如:窗户框、门框和楼板等。开滦赵各庄矿胶合木厂,自从58年4月起开始制造各种菱苦土建筑物。根据目前煤炭工业的发展速度,坑木供给量是不足于要求的,为了解决这一问题,开滦赵各庄矿胶合木厂的职工,在党的领导下,大胆地提出了用菱苦土等混合物作为井下坑木代用品,并进行了一系列的试验,58年11月我们合肥工业大学采矿工程系学生到该矿进行现场教学,在党的领导与支持下,我们接受开滦煤矿总管理处技术处的委托和工人同志在一起共同研究,经过130多次的试验。终于成功了,把菱苦土支架的抗压强度由113~(kg)/cm~2提高到481~(kg)/cm~2,超过了一般的木材。因而可作坑木的代用品。
The use of bitter-soil raw materials in China’s construction industry has begun to be widely used. The use of many units has shown that the bitter-soil and sawdust are blended together and mixed with brine to make wood substitutes. : Window frames, door frames and floor slabs. Kailuan Zhaogezhuang Mine Glue Wood Factory, since April, 58 began to manufacture all kinds of Ramon soil buildings. According to the current speed of development of the coal industry, the supply of pit wood is insufficient, and in order to solve this problem, the workers of the Zhaojizhuang Glue Woodworking Plant in Kaifeng have boldly proposed to use the Lingkuang under the leadership of the Party. The mixture was used as a substitute for underground pit wood and a series of tests were conducted. In November of the same year, students from the Department of Mining Engineering at Hefei University of Technology went to the mine for on-site teaching. Under the leadership and support of the party, we accepted the Kailuan coal mine. The commission’s technical department commissioned the work together with the workers’ comrades and conducted more than 130 experiments. It was finally successful, and the compressive strength of the Rambutan bracket increased from 113 kg/cm2 to 481 kg/cm2, which exceeded that of ordinary wood. It can be used as a substitute for pit wood.
