摘要
采用CCD摄像法观测气泡粘附纤维的微观行为,考察纤维性质、表面活性剂和CaCl2对气泡粘附纤维的影响.实验结果表明:加入非离子表面活性剂TX-100或阴离子表面活性剂油酸钠都不利于气泡粘附纤维;相对于长纤维(1.1,mm),气泡更容易粘附短纤维(0.6,mm);AKD施胶过的纤维更容易粘附在气泡上;碱性(pH=10.5)条件下加入CaCl2将有利于气泡对纤维的粘附.
Effect of fiber properties,surfactant and CaCl2 on the bubble-fiber attachment were investigated with CCD in this research. The results show that the addition of nonionic surfactant TX-100 or anionic surfactant sodium oleate cannot en-hance the attachment. Compared with long fiber（1.1,mm）,bubble is prone to attach short fiber（0.6,mm）. Bubble is easy to attach AKD sized fiber. Under alkaline conditions（pH=10.5）,the addition of CaCl2 can enhance bubble-fiber attachment.
