摘要

研究了在陶瓷浆料中加入玻璃纤维对浆料粘度及陶瓷坯体抗拉强度的影响。选择的陶瓷坯体以石英砂、硅溶胶为主要原料

玻璃纤维的直径为16μm

长度为1～3mm。结果表明

在陶瓷型中加入一定量的玻璃纤维后

陶瓷型的抗拉强度会升高;在焙烧温度为400℃时

在一定范围内

随着玻璃纤维增加

陶瓷型抗拉强度呈线性增加

从0.175MPa增加至0.221MPa

陶瓷浆料的粘度也会呈指数形式增大。

Abstract

Effects of glass fiber addition on the viscosity of the ceramic slurry and the tensile strength of ceramic green body for investment casting were investigated.Ceramic green body is mainly made from quartz sand and silica sol

and glass fiber is approximately 16 μm in diameter and 1

mm in length.The results indicate that

with a certain amount of glass fiber addition

tensile strength of the samples is increased with the temperature increases.Within a certain range

the tensile strength of the ceramic mold is increased linearly from 0.175 MPa to 0.221 MPa with increasing in glass fiber sintered at 400 ℃

and the viscosity of ceramic slurry is increased in an exponential form.
