摘　　要：以某建筑陶瓷配方料为研究对象,加入市售陶瓷减水剂五水偏硅酸钠、三聚磷酸钠以及低分子有机陶瓷减水剂腐植酸钠,并对所述陶瓷减水剂进行复配,通过对泥浆的流动性、比重、含水率、ζ电位、及触变性的测定,评价陶瓷减水剂及其复配对陶瓷配方土的减水效果。研究发现,单一陶瓷减水剂五水偏硅酸钠、三聚磷酸钠、腐植酸钠加入陶瓷配方土后,泥浆的性能不佳。但复配后的陶瓷减水剂可以使泥浆的性能提高,达到建筑陶瓷生产需求。当0.3%五水偏硅酸钠和0.1%腐植酸钠复配时,流速为34 s,触变性为1.029;当0.5%五水偏硅酸钠和0.15%的三聚磷酸钠复配时,流速为52 s,触变性为1.019;当0.1%三聚磷酸钠,0.3%五水偏硅酸钠和0.2%腐植酸钠复配时,流速达到44s,触变性为1.023。The dispersive effect of commercial ceramic deflocculates and their mixtures, such as sodium metasilicate pentahydrate, sodium tripolyphosphate, humic acid sodium salt, on a building ceramic slurry has been evaluated through the observation of the slurry＇s fluidity, density, water content, zeta potential, and thixotropy. It has been shown that a single deflocculate has inadequate dispersive effect on the building ceramic slurry, but their mixture could improve their performance and make the slurry meet the industrial requirements. With the addition of 0.3% sodium metasilicate pentahydrate and 0.1% humic acid sodium salt, the flow rate is 34 s, and the thixotropy is 1.029. When 0.5% sodium metasilicate pentahydrate and 0.15% sodium tripolyphosphate have been added, the flow rate reaches 52 s, and the thixotropy is 1.019. When 0.1% sodium tripolyphosphate, 0.3% sodium metasilicate pentahydrate and 0.2% humic acid sodium salt have been added, the flow rate is 44 s, and the thixotropy is 1.023.
