主要研究了固相含量与粘度、消泡剂和石膏模对亚氨基二乙酸改性S iC料浆注浆成形坯体密度的影响。结果表明,当料浆固相含量较低、粘度较小时,增大固相含量能提高坯体密度;而当固相含量较高、粘度较大时,降低粘度能有效地提高坯体密度。加入适量合适的消泡剂可适当提高坯体的致密性,同时石膏模的成分和膏水比对坯体密度的影响较大。当半水石膏的两种类型的比例(β/α)为5∶5、膏水比为1.8∶1时,注浆成形坯体密度达最大,为2.5894 g/cm3。
主要研究瞭固相含量與粘度、消泡劑和石膏模對亞氨基二乙痠改性S iC料漿註漿成形坯體密度的影響。結果錶明,噹料漿固相含量較低、粘度較小時,增大固相含量能提高坯體密度;而噹固相含量較高、粘度較大時,降低粘度能有效地提高坯體密度。加入適量閤適的消泡劑可適噹提高坯體的緻密性,同時石膏模的成分和膏水比對坯體密度的影響較大。噹半水石膏的兩種類型的比例(β/α)為5∶5、膏水比為1.8∶1時,註漿成形坯體密度達最大,為2.5894 g/cm3。

In this paper ,the effects of solid loading ,viscosity ,defoaming agent and cast on the density of body which was formed by slip casting with iminodiacetic acid coated SiC slurry were studied .The results indicated that increasing solid loading could improve the density of body when the slurry had lower solid loading and viscosity ,and reducing viscosity could improve the density of body when the slurry had higher solid loading and viscosity .It could improve the densification of body through adding some suitable defoaming agent ,and there were some impacts on the density of body that components and the ratio of gypsum powder to water of cast .When semi-hydrated gypsumβ/αwas 5∶5 and the ratio of gypsum pow-der to water was 1 .8∶1 ,the density of body by slip casting achieved biggest and was 2 .589 4 g/cm3 .
