摘要
详细研究了不同频率下水溶性高分子溶解过程中可溶盐(KC l、N aC l、N aB r)及EDTA对其声衰减效果的影响。试验结果表明,在低频条件下可溶盐对水溶性高分子溶解过程中的声衰减有明显的影响,若在其中加入EDTA可以基本消除这种“盐效应”的影响。
The effects of sahs(KCl, NaCl, NaBr) dissolved in solution on the sound attenuation of water-soluble polymers in the process of dissolving at different frequency were studied in details. It shows that the salts affect the sound attenuation of water-soluble polymers and this salts effect is reduced by EDTA at low frequency.
