摘要： The present invention relates to a manufacturing method of polyaspartic acid. More particularly, the present invention relates to a manufacturing method of polyaspartic acid comprising steps of carrying out condensation polymerization of maleic anhydride and ammonia in the presence of a polar solvent without active hydrogen to give polysuccinimide and hydrolyzing the resulting polysuccinimide to obtain polyaspartic acid. Specifically, the present invention is characterized in that the quality of the synthetic product, polysuccinimide and polyaspartic acid, is improved by minimizing the decomposition and the degradation of the maleic acid during the process of the polymerization resulted from the introduction of substituent to maleic acid.

摘要： A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.

摘要： Provided is a complex sintering furnace to sequentially perform a bake-out process and a sintering process for molding ceramic products. The complex sintering furnace includes: a support frame; a pair of furnace bodies supported on the top of the support frame and having a built-in heat insulator covered by a disc-shaped cover; a pair of rails arranged under the support frame in parallel in a length direction along arrangement of the furnace bodies; a rotating base horizontally transferred along the rails and rotatably connected to bottoms of the furnace bodies when the rotating base is vertically transferred directly under the bottoms of the furnace bodies, the rotating base including a separately rotating setter mounted the top thereof; and an ascending/descending apparatus mounted under the rotating bases and having a ball-screw type rotation shaft to vertically ascend/descend the rotating base at the same time of the separate rotation of the setters. Accordingly, the production efficiency of the ceramic products can be significantly improved by rapidly transferring to the post-processes and simultaneously performing the bake-out process and the sintering process.
