The invention provides an anode module structure of a wet type tubular electric precipitator. The anode module structure of the wet type tubular electric precipitator comprises a plurality of single conductive fiber reinforced plastic tubes. Glass fiber layers cover the outer walls of the single conductive fiber reinforced plastic tubes. The single conductive fiber reinforced plastic tubes are bonded through resin to form a honeycomb-shaped anode module. A fiber reinforced plastic layer covers the circumferential outer wall of the anode module to form an integral reinforced layer. A fiber reinforced plastic layer covers the lower end of the anode module to form a lower-end reinforced strip. A sealing flange and a load-bearing flange sleeve the upper end of the anode module, the sealing flange is located on the top edge of the anode module, a plurality of reinforcing rib plates are arranged between the sealing flange and the load-bearing flange, and an anode line channel is formed in the top surface of the sealing flange in a concave mode. Equi-potential paste heads coat the upper end and the lower end of the anode module, and further coat the inner wall of the anode line channel and the top surface of the sealing flange. Anode lines and carbon fiber resin filling materials are placed in the anode line channel, and a fiber reinforced plastic plate is arranged in the channel opening of the anode line channel in a sealing mode.

The invention discloses a preparation method of a net-shaped copper foil for a lithium ion battery, belonging to the technical field of the preparation of lithium ion batteries. The preparation methodis characterized by comprising the following steps: (1) carrying out activated cleaning treatment on the surface of a copper foil; (2) pasting a sensitization dry film to the activated cleaned copperfoil, and carrying out exposure development; (3) etching the developed copper foil, and sequentially carrying out film striping and cleaning; and (4) carrying out surface passivation on the cleaned copper foil by virtue of passivation liquid, and carrying out washing and drying, so as to obtain the net-shaped copper foil. The preparation method has the beneficial effects that the requirements ona grinding mill is relatively low in requirement, a punched hole is unlikely to be deformed, no burr is formed on the surface of a through hole, the copper foil is unlikely to be worn during the striping, and the cost is relatively low; and the preparation method is used for preparing the net-shaped copper foil.

The invention relates to an aluminum electrolytic technology, more specifically relates to a preheating and roasting method for an aluminum electrolytic tank, especially provides a method for roasting the aluminum electrolytic tank with a special-shaped cathode structure. The invention solves the technical problem that the aluminum electrolytic tank with special-shaped cathode structure can be roasted by reducing the amount of a carbon material. The roasting method comprises the following steps: A, filling a basic material in a special-shaped cathode groove, wherein the basic material can not contact with anode; B, laying the carbon material on a convex plate of the special-shaped cathode, wherein the carbon material is contact with anode; C, electrifying and roasting; wherein the basic material is an electrolyte block or / and cryolite. One of the electrolyte block and cryolite can be selected, or a mixture of the electrolyte block and cryolite can be used; any proportion can be employed for mixing. The roasting method of the invention can reduce the carbon material amount, the workload for fishing, and the phenomena of overburn and chipping. The method of the invention provides an effective method for roasting the aluminum electrolytic tank.
