Abstract

The invention relates to a cross-linking and curing polymer film forming mold and a using method thereof. The cross-linking and curing polymer film forming mold comprises a mold cavity and a mold cover plate, a plurality of first bosses are arranged on the side, facing the mold cavity, of the mold cover plate in an array mode, and a plurality of second bosses are arranged at the bottom of the mold cavity in an array mode; the first bosses and the second bosses are arranged in a staggered and equidistant mode. A plurality of air holes are further formed in the mold cover plate in an array mode, and the positions of the air holes correspond to the positions of the second bosses in a one-to-one mode. The first boss and the second boss are each of a regular quadrangular frustum pyramid structure, a three-dimensional groove of the regular quadrangular frustum pyramid structure can be formed in the formed cross-linked cured polymer film, permeation and diffusion of feed liquid are facilitated, and the permeation flux of the film is improved.

Description

technical field [0001] The present application relates to the technical field of preparation of polymer separation membranes, and in particular to a molding die for preparing a cross-linked cured polymer membrane and a method for using the same. Background technique [0002] Gasoline is the most important fuel in the industrial society, and at the same time, the combustion products of gasoline are also the most direct source of pollution of sulfur oxides in the air. In order to protect the environment, the production of clean gasoline with ultra-low sulfur content has become an important issue worldwide. [0003] At present, the desulfurization membranes used for pervaporation are mainly two-dimensional polymer membranes, such as polydimethylsiloxane PDMS, polyethylene glycol PEG, ethyl cellulose EC, polyether block amide PEBAX, polyamino Formate PU, polyimide PI. The low permeation flux of polymer membranes severely restricts the industrial application of permeable membra...
