DETACHABILITY IMPROVER OF CAKE FROM FILTER CLOTH OF SQUEEZE TYPE DEHYDRATOR USING FILTER CLOTH AND DETACHMENT METHOD OF CAKE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a detachability improver of a cake from a filter cloth of a squeeze type dehydrator using the filter cloth, improving detachability of the cake by preventing adhesion of a cake thin layer onto the filter cloth, improving filtration cycle by reducing cleaning frequency of the filter cloth and capable of reducing moisture content of the cake, and a detachment method of the cake from the filter cloth of the squeeze type dehydrator using the same.SOLUTION: The above described problem is solved by a detachability improver of a cake from a filter cloth of a squeeze type dehydrator using the filter cloth, containing polydiallyldimethylammonium salt having molecular weight of 10,000 to 200,000, and one or more kind of surfactant selected from a cationic surfactant, a nonionic surfactant and an ampholytic surfactant as active ingredients.SELECTED DRAWING: Figure 1
