The results of experiment show the glass fiber dealed with by KH550 is notscattered in these solvents such as the water, the component solvent of phenol andtetrachloroethane, and ethyl alcohol solution of KH550, but it is evenly scattered inthe solution of PET, the concentration of which has great effect on the dispersion ofglass fiber. The glass fiber can' t be scattered when the value of consistency is below0.2664g/ml, and 0.75g glass fiber can be scattered in 100ml solution.

本实验通过对玻璃纤维分散的研究发现，玻璃纤维(长 3mm，经 KH550 处理)在水、苯酚/四氯乙烷、KH550 的乙醇溶液中都不能分散，而在 PET 的苯酚/四氯乙烷溶液中能均匀分散，且溶液的浓度对分散性影响很大，当浓度。2664g/ml 时，玻璃纤维不能分散，玻璃纤维在 100ml 浓度为 0.4444g/ml 的溶液(90℃下，PET 的饱和溶液)中的最大分散量为：0.75g。
