[0118] The method for preparing a reverse osmosis membrane according to the third embodiment of the present invention includes the following steps:

[0119] Step S1: providing a roll of base film;

[0120] Step S2: making the basement membrane tense;

[0121] Step S3: pre-storing the unrolled base film;

[0122] Step S4: dragging the base film for dip coating;

[0123] Step S5: Dewatering the base film for the first time;

[0124] Step S6: extrusion coating the base film;

[0125] Step S7: Dewatering the base film for the second time;

[0126]Step S8: Dry the base film; specifically, provide hot air to the opposite sides of the base film at the same time, the hot air on the side of the base film away from the ground is provided by the first air nozzle, and the hot air on the side of the base film close to the ground Provided by the second air nozzle, the first air nozzle is a linear air outlet structure, and the second air nozzle is a planar air outlet structure;

Abstract

The invention provides reverse osmosis membrane production equipment used for forming a reverse osmosis membrane after technological treatment is carried out on a basement membrane. The reverse osmosis membrane production equipment comprises an unwinding device, a coating device, a drying device and a winding device, wherein a basement membrane provided by the unwinding device is coated by virtue of the coating device and then enters the drying device, and the basement membrane is suspended in the air, dried by the drying device and then wound by the winding device. The invention also provides a reverse osmosis membrane production method used for forming a reverse osmosis membrane after the technological treatment is carried out on the basement membrane. The production method comprises the following steps of: S1, providing a basement membrane roll; S2, coating the basement membrane; S3, suspending the basement membrane in the air and drying; and S4, winding the basement membrane. The reverse osmosis membrane produced by adopting the reverse osmosis membrane production equipment provided by the invention and the reverse osmosis membrane prepared by adopting the reverse osmosis membrane preparation method provided by the invention respectively have the advantages of good quality and the like.

Description

【Technical field】 [0001] The invention relates to the production field of reverse osmosis membranes, in particular to a reverse osmosis membrane production equipment and a reverse osmosis membrane preparation method. 【Background technique】 [0002] The reverse osmosis membrane is the core component to realize reverse osmosis. It is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. Generally made of polymer materials, such as cellulose acetate membrane, aromatic polyhydrazide membrane, aromatic polyamide membrane, etc. [0003] With the expansion of the market demand for reverse osmosis membranes and the higher and higher quality requirements for reverse osmosis membranes, the quality of the existing reverse osmosis membrane production equipment and the reverse osmosis membrane prepared by the existing reverse osmosis membrane preparation method is not ideal , reverse osmosis membrane production equipment ...
