含有机胶凝剂的Al2O3-SiO2系泡沫料浆的流变性能与固化特性
Rheological Properties and Curing Characteristics of Al2 O3-SiO2 Foam Slurries Containing Organic Gelling Agent
摘要
Abstract
The direct foaming method combined with gelcasting was employed to prepare mullite ce-ramic foam . Triacetin , polyimide and hydroxypropyl cellulose w ere creatively proposed as gelling agent for gelcasting process ,respectively .The influence of gelling agent on rheological properties and the correlation rule with the curing time were studied .The results show that different kinds of gelling agent have different influence on rheological properties .It is considered that the rheological properties have significant influence on the curing time .Ameliorating the thixotropy ,improving the rate of vis-cosity growth ,and enlarging the linear viscoelastic domain of foam slurry are conducive to shorten the curing time of foam slurry . Among these three gelling agents , the triacetin obtains the optimal effects ,the initial curing time and curing time of foam slurry is both shortest .关键词
