Investigation of swelling-dissolving property of KGM-borate composite gel
KGM-borate composite gel was prepared and its swelling-dissolving property had been investigated. A dialectic relation between swelling and dissolving was concluded. Result of orthogonal test indicated that the effects of each factor on dissolving ratio of gel from great to minor were as followed: temperature, the number of freezing-thawing cycles, concentration of borate and concentration of salt hydronium. Effects of all the factors were not remarkable. The working mechanism of each factors was deduced primarily.
