钠钙玻璃在不同液体环境中的磨损性能
|
摘要
以Pyrex玻璃球作为对磨副,研究了钠钙玻璃在不同液体环境下的磨损性能。研究发现,相比于纯水环境,钠钙玻璃在酸性溶液(p H=3)和碱性溶液(p H=11)中的磨损量分别降低了约33%和30%。当溶液中存在的带正电的聚合电解质通过静电作用力吸附在钠钙玻璃表面时,可有效提高玻璃表面的抗磨损性能,磨损量最大可降低约94%;当溶液中存在其他类型的聚合电解质时,钠钙玻璃的磨损量无明显变化。
The friction and wear of soda lime(SL) glass in various aqueous solutions were investigated by rubbing against pyrex glass ball.The results show that,compared to pure water,wear volume of soda lime glass in acid solution(i.e.,p H=3) and basic solution(i.e.,p H=11) are decreased by 33% and 30%,respectively.It is indicated that the chemical reactions at the sliding interface in solution are different from the corrosion reactions without any interfacial shear.The addition of cationic polyelectrolyte into the solution can suppress the wear of SL glass and pyrex ball surfaces,while anionic polyelectrolyte does not reduce wear at all.It is suggested that cationic polymers could absorb on the glass surface due to the electrostatic reactions,enhancing the wear resistance of SL glass.
