基于挤出成型的陶瓷膏体的制备与分析
|
摘要
为实现陶瓷膏体3D打印铸型来取代传统的蜡模制壳,选择以固相含量、pH值、分散剂3个因素进行正交试验。通过对粘度的测试与分析,研究氧化铝陶瓷膏体的流变性能及最优配比方案。结果表明,分散剂对膏体粘度的影响最大,pH值次之,固相含量影响最小。采用氧化铝粉末51%,柠檬酸钠0.5%,丙三醇4%,聚乙烯醇2.25%,蒸馏水42.25%,pH呈碱性的配比方案,膏体的流变性能最好。
In order to realize the 3 D printing casting of ceramic paste to replace the traditional wax mold for shell making,orthogonal tests were conducted on three factors: solid phase content, pH value and dispersant. The rheological properties and optimal ratio of alumina paste were studied by viscosity measurement and analysis. The results show that dispersants have the greatest influence on paste viscosity, followed by pH value and the least influence on solid content. Aluminum oxide powder is used 51%, sodium citrate 0.5%, glycerin 4%, polyvinyl alcohol 2.25%, distilled water 42.25%, alkaline pH ratio scheme, paste rheology can be the best.
