在合肥市环卫处的大力支持下,我厂利用经过处理的城市垃圾,代替煤灰烧结普通粘土砖。经过多次试验,我们发现用垃圾烧砖不仅可以提高红砖的质量,而且为提高经济效益带来了多方面的好处。一是提高了质量。用垃圾烧的红砖平均合格率提高了15%。其抗折、抗压强度均在150公斤/平方厘米以上,尤其是产品的外观质量有了明显的提高。这是因为垃圾的颗粒度细小,没有杂质,因此红砖表面十分光滑平整,棱角分明。二是节约了能源。根据焙烧投
With the strong support of the Sanitation Department of Hefei City, our factory uses treated urban waste instead of coal ash to sinter common clay bricks. After many experiments, we found that using bricks made from refuse can not only improve the quality of red bricks, but also bring many benefits for improving economic efficiency. The first is to improve the quality. The average pass rate of rubbish-fired red bricks increased by 15%. Its flexural and compressive strengths are all above 150 kg/cm2, especially the appearance quality of the product has been significantly improved. This is because the granularity of the refuse is small and there is no impurity, so the surface of the red brick is very smooth and flat, with sharp edges and corners. The second is to save energy. According to the roasting cast
