The invention provides a process for manufacturing a box body and a cover plate as well as the box body and cover plate manufactured by the manufacturing process. The box body is provided with an opening (12'), the cover plate (11) is arranged at the opening (12') of the box body. The manufacturing process includes: a stretching working procedure, namely stretching processing is carried out on a plate (1) used for forming the box body, so as to form a sunk part (2) larger than the opening (12'); a blanking working procedure, namely blanking processing is carried out on the sunk part (2) of the plate (1), so as to separate the cover plate (11); and a levelling working procedure, namely the rest part (21b) of the sunk part (2) on the plates (1) is levelled, so as to form an opening (12') which is coincident with the periphery of the cover plate (11). Thus the box body and cover plate can be simultaneously processed on one plate, not only waste material produced when processing the opening is reasonably utilized, but also two processing working procedures are combined, so that working procedure is saved.

The invention discloses a semiconductor production equipment support which comprises a cuboid-shaped support body. The interior of the support body is hollow, and one front face of the support body is open; a cube-shaped positioning block is fixed at one end of the support body in the length direction, a positioning hole is formed in the positioning block, and the included angle between the axis line of the positioning hole and the center line of the support body in the length direction is 45 degrees; an inverted-T-shaped positioning plate is fixed on the lower end face of the support body and located at the other end of the support body in the length direction. Due to the fact that the included angle between the positioning hole formed in the positioning block and the support body is 45 degrees, the support can be conveniently assembled, and the assembling efficiency is improved; through the design of the inverted-T-shaped positioning plate, the structure of the support better meets the assembling requirements, manpower needed by assembling can be reduced, and the assembling quality is guaranteed.

The invention relates to a preparation method of a porous ion conduction membrane for a flow battery. One or two or more organic polymer resins are used as raw materials, and the raw materials are dissolved in an organic solvent, then immersed in the poor solvent A of the resin, and transferred to the poor solvent bath B of the resin after a certain period of time. Using the two-step immersion-precipitation phase inversion method, by controlling the exchange rate of solvent-non-solvent, the thickness of the separation layer and the dense layer can be precisely regulated, so that ion conduction with a thin and dense separation layer and a loose porous support layer structure can be obtained. membrane.
