摘要
对南通地区以长江淤泥、内河淤泥、滩涂淤泥为原料的烧结砖等相关产品进行性能测试,通过对原料、生产工艺的分析,讨探了南通地区淤泥多孔砖外观质量存在问题的起因.测试及分析结果显示,大部分产品满足相关标准要求,但有部分产品的外观质量存在尺寸偏差较大的问题,其主要原因是在生产过程中忽视了淤泥与粘土在性能和生产工艺上的差异,从而导致煅烧过程中坯体收缩过大.
The appearance quality of silt fired perforated bricks was researched which was manufactured by Changjiang river silt, freshwater silt and beach silt in Nantong region. On the basis of analysis of raw materials and production technology, the causes of problems of appearance quality were investigated.The research results showed that a majority of products met the demands of correlated standards. But there were some deviations in the appearance of some products in size, which may be caused by the shrinkage of raw materials during roast process without considering the difference between the performance and the production technology of silt and clay.
