The invention relates to a preparation method of a fullerene-polyimide conductive film, which comprises the following steps: (1) adding solvents of o-dichlorobenzene and ODA in a container, adding PMDA while stirring, reacting for 3 hours to generate a polyamide acid solution; (2) adding fullerene powder into the above solution, performing ultrasonic processing for 2 hours, keeping the temperature at 25-35 DEG C during the ultrasonic process to obtain a fullerene-polyamide acid solution; (3) spreading the above solution on a glass plate, strickling the film, removing the solvent of o-dichlorobenzene in a common baking oven, putting the film in a vacuum baking oven to realize complete imidization of fullerene-polyamide acid so as to obtain the fullerene-polyimide conductive film. The preparation method of the invention can reduce surface conductivity of polyimide, prevent static electricity, and extend the application scope.

A natural adaptogenic tea is prepared from adaptogens to counter adverse physical, chemical, or biological stressors and to promote t-cell activity and k-cell activity. Also, the composition is high in antioxidants and discourages free radicals. Moreover, the composition improves liver performance, resulting in improved toxin removal and improved nutrient absorption. In addition to these benefits, the composition improves capillary dilation, thereby providing better oxygenation to the brain. The tea is prepared from adaptogens including rhodiola, ashwagandha, schizandra berry, eleuthero and astralagus. Also, the tea includes damiana leaf, passion flower, milk thistle, white willow bark, goji berry, mangosteen, pomegranate, green tea, and sarsaparilla.

The invention discloses a network information transmitter, comprising a data line, the top of the data line is fixedly connected to an organic body, the lower surface of the body is fixedly connected with a bracket, and the top of the bracket is provided with an interface. The invention relates to network information Transmission technology field. The network information transmitter, by setting the body, when the equipment is in use, the data line and the interface are responsible for the transmission of the data signal, the electronic components are fixedly installed on the upper surface of the support plate, the dust removal device at the bottom of the partition plate rotates, and the air outside the equipment flows from The gap of the bracket enters the inside of the air cooling device, the external cold air passes through the partition and the support plate from bottom to top, the cold air flows over the outer surface of the electronic components, the cold air is heated, and the hot air is discharged from the air outlet. The liquid cooling device can also convert a part of the heat. Under the combined action of air cooling and liquid cooling, the heat inside the device can be quickly dissipated outwards, which solves the problem of slow heat dissipation of traditional network information transmitters.

A preparation method of graphene-blending polyimide conductive film comprises the steps of: (1) adding solvent methyl acetate, heterocyclic amine and ODA (octyl decyl adipate) into a container, adding PMDA (pyromellitic dianhydride) while stirring, and reacting for 3h to generate a polyamic acid solution; (2) adding graphene powder into the polyamic acid solution, ultrasonically treating for 2h, keeping the temperature at 25- 35 DEG C during the ultrasonic process to obtain a graphene-polyamide acid solution; and (3) coating a glass plate with the solution and scraping to smooth, removing the solvent methyl acetate in an ordinary oven, and placing in a vacuum oven for complete imide- amination of graphene-polyamide acid to obtain a graphene-blending polyimide conductive film. The preparation method can reduce the polyimide surface conductivity, prevent static electricity and enlarge scope of application.

The invention discloses an installing structure of an automobile top cover decoration strip. The installing structure comprises the top cover decoration strip and a groove formed by overlapping a side wall and a top cover. The installing structure further comprises a clamping base adhering to the bottom wall of the groove. The top cover decoration strip comprises a decoration strip body, an elastic buckle body is connected to the middle of the lower portion of the decoration strip body and matched with the clamping base in a clamped mode, and lip sides are arranged on the left and right sides of the decoration strip body respectively and are in interference fit with the two side walls of the groove respectively. The installing structure is reliable in connection, not prone to warping and beneficial to sealing, and installing precision is easy to control.

The invention discloses a segmented joint structure of a prefabricated underground continuous wall, which belongs to the field of continuous walls. When pouring concrete, the carbon dioxide aqueous solution in the liquid storage ball is shaken to promote the carbon dioxide to overflow into the straight cylinder, and the piston is pushed to squeeze the fixed pipe and extend to the At the same time, when the flexible sheet is squeezed to the vertical state, the two oblique rods are driven to squeeze the reed, so that the limit block extends into the limit groove seat, and punctures the film, so that the wet water The sticky layer becomes viscous when it encounters water, which promotes the tight adhesion and fixation of the limit block and the limit groove seat, strengthening the connection stability, and the stretching capsule is stretched along with the reed, so that the thick rod pulls the moving plate and the pulling rod to move , prompting the phase change support rod to be stretched, and under the action of tension, it changes from soft to hard to form a rigid support rod, which not only effectively slows down the impact of concrete pouring, but also prevents the adhesion of the limit block and the limit slot seat. The limit provides support firmness and enhances connection stability.

The invention belongs to the technical field of angle iron, and particularly relates to multi-working-face industrial angle iron which comprises a base, a cavity is formed in the base in the length direction of the base, a sliding groove is formed in the upper surface of the base in the width direction of the base, and the sliding groove communicates with the cavity; the first angle iron comprises an upper plate, a transverse plate and a connecting unit, the upper plate is arranged above the base in the length direction of the base, the transverse plate is arranged in the cavity in the length direction of the base, the transverse plate is matched with the cavity in size, and the upper plate is rotationally connected with the transverse plate through the connecting unit; the structure of the second angle iron is the same as that of the first angle iron; the fastening units are arranged on the two side walls of the base in the width direction and used for fixing the upper plate and the base; the angle iron is simple in structure, and the problem that some objects without vertical planes are difficult to fix by angle iron is solved.
