摘要
为解决煤矸石在制作墙地砖中硬度较高、塑性指数较低、干燥线收缩较大和含碳量高等问题 ,将微波辐照技术应用于煤矸石建筑墙地砖预破碎和干燥工艺中。试验证明 :该技术不但解决了用煤矸石研制建筑墙地砖技术难点 ,而且也为开发建筑墙地砖原料和提高墙地砖生产工艺科技含量 ,提供了一条新思路。
In order to solve such problems as high hardness, poor plasticity, large drying linear shrinkage and high carbon content of gangue in wall bricks and floor tiles, a microwave radiation techique is applied in the precrushing and drying process for manufacturing wall bricks and floor tiles. The tests have shown that the technique can not only overcome the technical difficulty in manufacturing of wall bricks and floor tiles, but also provide a new way out for exploiting their raw materials and increasing their content of science and technology.
