This invention provides an MXene-AP-HOPO self-supporting composite membrane for uranium-containing wastewater treatment, its preparation method, and its application. Specifically, it relates to an MXene-AP-HOPO self-supporting composite membrane for uranium-containing wastewater treatment. The composite membrane is a three-dimensional porous self-supporting membrane structure formed by amino-functionalized MXene nanosheets as a substrate and hydroxypyridinone functional monomers covalently coupled to the substrate via amide bonds. The composite membrane of this invention, by leveraging the high specific coordination ability of HOPO for uranyl ions and the excellent structural properties of MXene, solves the defects of HOPO due to its high water solubility, such as easy dissolution and loss in aqueous solutions, and the poor reusability of existing HOPO-based adsorbent materials. It also overcomes the problems of traditional powder adsorbents, such as difficult solid-liquid separation, easy agglomeration, high recycling costs, and difficulty in adapting to continuous industrial processes, thus achieving efficient treatment of uranium-containing wastewater and convenient recycling and reuse of materials.

The application discloses a kind of manufacturing methods of anti-falling coating film aluminum roll.The method comprises the following steps: obtaining aluminum roll substrate and carrying out pretreatment, obtain activated aluminum roll;The surface of activated aluminum roll is coated with glue layer, and the edge area is increased, to obtain the aluminum roll of gluing;Collect the process parameters of gluing aluminum roll, and carry out tension compensation based on dynamic tension prediction model, the output torque of unwinding motor is adjusted to compensate and control the conveying tension of gluing aluminum roll, generate tension compensation data;Glue layer thickness data is obtained, and according to glue layer thickness data and tension compensation data, film material is gradient hot-pressing composite with gluing aluminum roll, to obtain composite aluminum roll;Edge stress distribution data of composite aluminum roll is detected;Based on edge stress distribution data, local secondary hot-pressing is carried out on composite aluminum roll, to obtain coating film aluminum roll.The application realizes the anti-falling control of coating film aluminum roll by zoned gluing and dynamic tension and gradient hot-pressing.
