凝胶结构提高了粘结液相的粘度和表面张力，毛细力增大，生球抗压强度提高。
The viscosity and surface tension was improved by gel structure of bentonite colloid, so the capillary force is increased and therefore the wet compression strength is improved.
结果表明，钠基膨润土能使生球落下强度、抗压强度显著提高；而钙基膨润土在改善球团爆裂温度方面优于钠基膨润土。
The results show that sodium bentonite can greatly improve the drop strength and compressive strength of green pellets, while calcium bentonite could enhance shock temperature of green pellets.
