Description

Technical Field

[0001] The utility model relates to membrane preparation equipment, in particular to a reverse osmosis membrane wrinkle prevention device. Background Art

[0002] Reverse osmosis membranes are the core component of reverse osmosis. They are artificial semipermeable membranes with specific properties, mimicking biological semipermeable membranes. They are generally made of polymer materials, such as cellulose acetate membranes, aromatic polyhydrazide membranes, and aromatic polyamide membranes. The diameter of the surface micropores is generally between 0.5 and 10 nm, and the permeability is related to the chemical structure of the membrane itself. As reverse osmosis technology matures, its application in water treatment is increasing.

[0003] Due to uneven film thickness and equipment tension, the film can shift and wrinkle when in contact with the shaft. If wrinkles aren't addressed promptly, they can lead to large amounts of film being scrapped and unusable. Currently, this problem is typically addressed by employee inspections. When wrinkles occur, wet film is pulled against the shaft, pulling the film to the sides, while dry film is slapped and pulled. This wastes manpower and creates the risk of hands being caught in the equipment's rollers when pulling and slapping the film. Utility Model Content
