PRODUCTION METHOD OF A FIBER HUECA MEMBRANE. |
| abstract |
Method of producing a hollow fiber membrane comprising: discharging a polyvinylidene fluoride solution comprising a polyvinylidene fluoride resin and a poor solvent, which is selected from the group comprising cyclohexanone, isophorone, gamma-butyrolactone and dimethyl phthalate , at a temperature above a phase separation temperature of said solution, in a cooling bath at a temperature below the phase separation temperature to coagulate the polyvinylidene fluoride resin; wherein the cooling bath contains 60 to 100 percent of said poor solvent; the polyvinylidene fluoride resin is dissolved in the poor solvent at a temperature of 80 ° C to 175 ° C to prepare a solution of polyvinylidene fluoride resin; the polyvinylidene fluoride resin solution contains from 20 to 60 percent by weight of polyvinylidene fluoride resin; the crystallization temperature of the polyvinylidene fluoride solution is in the range of 40 ° C to 120 ° C; The average cooling rate of the polyvinylidene fluoride solution, when the temperature of the polyvinylidene fluoride solution reaches the crystallization temperature during cooling, is in the range of 2 x 10 3 ° C / min at 10 6 ° C / min ; and the temperature of the Th row to discharge the polyvinylidene fluoride solution in the cooling bath and the crystallization temperature satisfy the ratio Tc <= Th> = Tc + 90. |
