外加剂对碳化硅-水系统流动性能影响研究

THE STUDY ABOUT ADMIXTURES HOW TO INFLUENCE THE FLOW PERFORMANCE OF SILICON-CARBIDE-WATER SYSTEM

碳化硅-水系统流动性能对碳化硅制品的密度有很大影响,本文用十二烷基硫酸钠、萘系磺酸盐UNF-5、柠檬酸三钠、碳酸钠、无水乙酸钠做减水剂对碳化硅-水系统流动性能进行了研究。实验结果表明,外加剂加入量对碳化硅-水系统粘度有较大影响,在所选外加剂中萘系磺酸盐UNF-5是降低粘度效果最好的,合适的加入量为0.3g/100gSiC;系统的pH值在7左右时,碳化硅-水系统粘度最小,粘度为17mPa·S。

The flow Performance of silicon-carbide-water system has significant impacts on the density of silicon-carbide products. This paper has studied the flow Performanc of silicon-carbide-water system with sodium dodecyl sulfate, Naphthalene Sulfonate UNF-5, Sodium citrate, sodium carbonate, Sodium acetate anhydrous as Superplasticizero The experimental results show that the amount of additive produces more effect on the viscosity of silicon-carbide-water system, among the Additives being selected Talampicillin Napsylate UNF-5 is the best one to reduce the viscosity, the Suitable dosage the is 0.3g/100gSiC; when the pH of the system is about 7, the viscosity of silicon-carbide-water system is smallest. 17mPa · S.
