Problems solved by technology

When designing membrane element products of each specification, it is necessary to tailor the size of the corresponding functional material according to its size design. When determining the size of each functional material, it is cut completely based on experience and estimation. If the cutting amount is rich, it will easily cause damage. Material waste and insufficient cutting can easily cause membrane products to be scrapped. This design method based on experience increases the difficulty of membrane element product design for R&D personnel, and also greatly increases the design and development cost of industrial membrane elements.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis membrane element rolling, in particular to a design method for a general-purpose industrial reverse osmosis membrane element product. Background technique [0002] As one of the core components of water treatment, reverse osmosis membrane elements are the key influencing factors to achieve deep filtration in the field of water treatment. Reverse osmosis technology has become one of the most widely used and fastest-growing technologies in my country. At present, reverse osmosis membrane elements are mainly It is composed of the following functional materials: water inlet screen, water production guide cloth, RO diaphragm, center rod and sealing glue. Although the composition and structure of functional materials of reverse osmosis membrane elements are roughly the same, due to the large number of specifications and models of membrane element products, there are differences in the design of t...
