Provided is a training box that is a practice tool for learning heart massaging (sternal compression) through experience; is low-cost, small-sized, light weight, and easy to transport; retains durability under repeated use; and on which AED use procedures can also be drilled. The portable practice tool for heart massaging in cardiopulmonary resuscitation is characterized by being provided with a chest-mockup main unit (1) having a thickness that is thicker than a thickness equivalent to the depth of chest cavity subsidence required during heart massaging (sternal compression), in which a palm-sized opening (3) in the center of the chest-mockup main unit (1) is opened in a vertical direction; a closed-cell synthetic resin foam (6a), which is covered by a bag (6d), contracts and expands in a vertical direction, and has a cavity (7) in the interior, is provided in said opening as a pressing part (6) that is moveable in the vertical direction; and a valve (8), which is for both the entrance and exit of air to the abovementioned cavity (7) and the detection thereof, is disposed on a side of the bag (6d).

The present invention separates a process method for manufacturing polymer ceramic pipeline lining, which is mainly composed of 70-90%wt ceramic powder, 5-25%wt polymer material and 0.1-5%wt curing agent raw material, First, mix and stir the above raw materials to form the enamel paint, calculate the amount of enamel paint added according to the length, thickness and specific gravity of the pipeline lining, add the enamel paint to the pipeline that is sealed and supported on the driving wheel, and the motor drives the driving wheel to make the pipeline in Rotate slowly and then quickly at 100 to 1000 rpm. During the rotation, the enamel paint is coated, formed and cured. The lining of the present invention not only has good strength, high hardness, high temperature resistance and corrosion resistance, but also has a uniform thickness. , dense, smooth and wear-resistant, long service life. At the same time, the device is compact and simple in structure, easy to operate, high in enamelling efficiency, and can realize large-scale production. Urban pipe lining processing.

The casing prepared by the preparation method of the casing of the present invention has a black and bright appearance and a ceramic texture. The invention also provides a casing manufactured by the method for preparing the casing and an electronic device using the casing.

The invention discloses a coiled core pipe with a uniform and rough surface. The coiled core pipe comprises a rotating cylinder, wherein a circular through hole is formed in the inner side of the rotating cylinder; a rotating sleeve is fixedly connected to the circular through hole of the rotating cylinder, and a circular through hole is formed in the outer side of the rotating sleeve; a connecting shaft is fixedly connected to the circular through hole of the rotating sleeve, and the length of the connecting shaft is greater than that of the rotating cylinder; and spraying particles are sprayed on the outer side of the rotating cylinder. According to the coiled core pipe with the uniform and rough surface, by arranging the spraying particles, when a copper aluminum foil is rotated, heading and priming can be well performed on the copper aluminum foil; when the rotating cylinder rotates the copper aluminum foil, the spraying particles are capable of straightening out an uneven surfaceof the copper aluminum foil, so that the phenomenon of wrinkling when the copper aluminum foil is rotated is avoided; and moreover, the spraying particles can be selected according to different thicknesses of the copper aluminum foils, so that friction force between the copper aluminum foil and the rotating cylinder is increased when the copper aluminum foil is rotated.

The invention discloses a processing process for plating gold on an insoluble metal wire. The processing process comprises the following steps: a gold plating device which is provided with a wire release wheel, a plating bath, a heating furnace and a wire winding wheel is adopted, a plating solution inside a plating solution pool flows through a graphite pipe to form circulation so that the plating solution circularly passes through the plating bath, and the insoluble metal wire to be plated, which is wound on the wire release wheel, is wound on the wire winding wheel sequentially from the graphite pipe and the heating furnace; the graphite pipe is connected with the positive electrode of a power supply to form an anode, the insoluble metal wire to be plated is connected with the negative electrode of the power supply to form a cathode, and the graphite pipe and the insoluble metal wire to be plated form a closed circuit through the plating solution; the wire winding wheel rotates to enable the insoluble metal wire to be plated to penetrate through the plating solution at a certain speed to form the insoluble metal wire with a surface plated with gold; and the insoluble metal wire plated with the gold passes through the heating furnace for heating so that a gold plating layer and the insoluble metal wire are closely combined. The processing process disclosed by the invention ensures that the gold plating layer of the insoluble metal wire is uniform and compact in thickness by adopting a continuous gold plating manner, so that the gold plating layer with the high smoothness is obtained.

The invention discloses a copper-bearing zinc impregnation agent and a method for zinc impregnation of a metal material. The copper-bearing zinc impregnation agent consists of zinc powder, lanthanum nitrate, ammonium chloride, copper powder and aluminum oxide. The method for the zinc impregnation of the metal material comprises the following steps: after a metal matrix is subjected to oil removal and rust removal treatment, the metal matrix and the copper-bearing zinc impregnation agent are placed in a sealed environment for annealing treatment and cooling. With the adoption of the copper-bearing zinc impregnation agent, the zinc activity can be improved, the zinc impregnation velocity can be raised, the self corrosion potential and the corrosion current density of the metal material can be reduced, and the corrosion resistance and the rigidity of the metal material can be improved.
