摘要
以固化剂、糊精、Na Cl和其它误差项为正交试验四因素合成陶粒,通过对筒压强度、堆积密度进行直观分析及筒压强度方差分析得较佳试验方案为固化剂:0.5%,糊精:0.3%,Na Cl的添加量对陶粒影响较小。通过重金属渗出率的测试,各重金属的含量未超出GB 5085.3-2007,符合投入生产并应用于生活标准。
Four factors of synthetic ceramic orthogonal test:the curing agent,the dextrin,the NaCl,the and the other error terms. Through the analysis of the cylinder pressure strength, packing density and the analysis of the variance of the cylinder pressure strength, the best experimental method as follows:curing agent is 0. 5 % and dextrin 0.3 % , the amount of adding NaCl less effected on the ceramsite. Through the test of heavy metal exudation rate test, the heavy metal content did not exceed the GB 5085.3-2007, and comformed to the input of production and applied to the standard of living.
