【摘要】：為研究油品火災(zāi)三相泡沫的發(fā)泡穩(wěn)定與流動(dòng)性能的關(guān)系,利用Waring-Blender方法對6種固相粉體制備三相泡沫,并分別以發(fā)泡高度、25%析液時(shí)間及表觀粘度為參數(shù),對其發(fā)泡穩(wěn)定及流變性能進(jìn)行表征,并通過Herschel-Bulkley方程對三相泡沫流變曲線進(jìn)行擬合。實(shí)驗(yàn)結(jié)果表明,親水及"兩親"粉體制備的三相泡沫具有較高的發(fā)泡高度及穩(wěn)定性,疏水粉體制備的三相泡沫的發(fā)泡及穩(wěn)定性能不足;流變測試結(jié)果顯示三相泡沫屬于屈服-假塑性流體且流變本構(gòu)方程與Herschel-Bulkley方程擬合較好,其中親水及"兩親"粉體制備的三相泡沫屈服-假塑性流體性質(zhì)較疏水粉體制備的明顯,表觀粘度較大,流動(dòng)性不足。
[Abstract]:In order to study the relationship between foaming stability and flow performance of three phase foam in oil fire, three phase foam was prepared by Waring-Blender method, and the foaming stability and rheological properties were characterized by the foaming height, 25% solution time and apparent viscosity, and the three-phase foam flow was carried out through the Herschel-Bulkley equation. The experimental results show that the three-phase foam prepared by the hydrophilic and "two parent" powder system has high foaming height and stability, the foaming and stability of the three-phase foam prepared by the hydrophobic powder system is insufficient, and the rheological test results show that the three phase foam belongs to the yield pseudoplastic fluid and the rheological constitutive equation and the Herschel-Bulkley equation. The fitting is better. The properties of the three phase foam yield pseudoplastic fluid prepared by the hydrophilic and "two parent" powder system are more obvious than those of the hydrophobic powder system, and the apparent viscosity is larger and the fluidity is insufficient.
