    A diaphragm or membrane suitable for cladding a cathode box (1) for use in an electrolytic cell and comprising a plurality of foraminate cathodes of the pocket type, the diaphragm or membrane comprising a sleeve portion (33) and a plurality of tabs (23,24,26,27) on both edges of the sleeve portion (33), and preferably two tabs on both edges of the sleeve portion, the dimensions of the sleeve portion (33) being such that, when the diaphragm is positioned in a pocket of the cathode box (1), the edges of the sleeve portion and the tabs thereon project beyond the extremities of the pocket so that they may be joined to the tabs and sleeve portions (33) of diaphragms or membranes in adjacent pockets of the cathode box.

    2. The method of mounting a hydraulically permeable diaphragm or a hydraulically impermeable membrane in an electrolyzer with finger type cathodes, is distinguished by the fact that, in order to simplify the maintenance of the electrolyzer, the diaphragm
    or the membrane is placed in the cathode chamber, the edges of each membrane or diaLragm are folded towards the adjacent diaphragms or membranes, smooth on a horizontal surface, and the membranes or diaphragms are interconnected.
    The invention relates to electrochemical production, in particular, to diaphragm electrolysis. Known hydraulically permeable diaphragm or hydraulically non permeable membrane for the electrolyzer with finger-shaped cathodes, made in the form of a plate. There is a known method of mounting a hydraulically permeable diaphragm or a hydraulically impermeable membrane for an electrolyzer with finger-like cathodes Cl. In an electrolyzer with finger-shaped cathodes, a diaphragm or membrane is mounted on the cathode finger and V-shaped clips are mounted on the diaphragm or membrane not near the junction between adjacent cathode fingers. ; The lack of a known membrane or diaphragm. And the method of its attachment is that the plate, which is placed on the finger-like cathodes, must be flattened, pressed tightly, and when mounted, V-shaped (Fixers must be careful not to tear the existing membrane or diaphragm. - The purpose of the invention is to simplify the servicing of an electrolysis cell. The aim is achieved by the fact that in a hydraulically permeable diaphragm or hydraulically impermeable membrane for an electrolyzer with finger-like cathodes, or the diaphragm is provided with an additional plate, the plates are connected at the ends and the end walls of the diaphragm or membrane extend beyond the edges of the plates.According to the method of mounting a hydraulically permeable diaphragm or hydraulically impermeable membrane in an electrolyzer with finger-like cathodes, the diaphragm or membrane is placed into the cathode chamber , bend the edges of each membrane or diaphragm in the direction of adjacent diaphragms or membranes, smooth along the horizontal surface, and the membranes or diaphragms are interconnected. Figure 1 is a diaphragm or membrane, isometric view; figure 2 is a cathode chamber with a diaphragm or membrane located in one of the cathode fingers, isometric view; Fig. 3 shows a cathode chamber with two pockets of the cathode chamber, having a diaphragm coating according to the invention, a plan view; Fig.4 part of the cathode chamber, in isometry. The membrane or diaphragm consists of plate 1, which is provided with an additional plate 2, both plates are connected at the ends, with the end walls 3 extending beyond the edges 4 of plates 1 and 2. When the diaphragm or membrane is inserted into the electrolyzer 5 with finger-shaped cathodes, the diaphragm or membrane projects above The lid of the electrolysis cell 6, similar to the lower part of the diaphragm / ly, protrudes below the level of the bottom of the electrolyzer 5. In order to: put a diaphragm into the electrolyzer, it is inserted into the cathode chamber 7, the end walls 3 and the diaphragm walls are bent to the poris oh KpHijKe b, as shown by the arrows in Figure 2, razglazhivayuts and are connected with the adjacent diaphragms. Also, the membrane is attached below. The diaphragms located in adjacent cathode chambers 7 are of such dimensions that the ends of the diaphragms are interconnected, the connection can be made by any means known in the art, for example by hot rolling. Compared with the prototype, the proposed diaphragm has the shape of a cathode chamber, therefore, it is not necessary to use V-shaped locks to mount it in the electrolyzer; as a result, the assembly is simplified and the possibility of rupture of the membranes or diaphragms is eliminated.
