The invention provides an improved packaging bag and an improved using method of the packaging bag. The improved packaging bag comprises a bag body used as a fan surface, a plurality of square piecesused for forming fan ribs are evenly distributed on the bag body at intervals, and one ends of the square pieces are sequentially hinged and connected through a hinge piece to form a folding fan. By means of the improved packaging bag, due to improved design of the packaging bag, multiple purposes of the packaging bag are achieved, the packaging bag can be used as the packaging bag and can also beused as the folding fan, the packaging bag can be used as the folding fan for air inducing and cooling in hot summer, a cool feeling is provided, and great convenience is brought to people.

The device (1) has an electric machine (5) with a stator (6) and a rotor (7). The rotor is arranged radially inside stator, and has a clutch (13) with a pressure plate (14) and a counter-pressure plate (15) and a clutch disc (19) that is arranged between pressure plate and counter-pressure plate and inside an output hub (20). The rotor is supported radially on inside by a rotor carrier (9) that is provided as cup-shaped element. The cup-shaped element has a wall portion (11) that extends in axial direction and a wall portion (12) that extends in radial direction.

Disclosed is a discrete flexible die. An upper discrete die is connected with an upper sider of a press, a lower discrete die is combined with a base of the press and comprises a lower die support, a top supporting plate of the lower die support is assembled with hydraulic tensioning sleeves, oil supply of each hydraulic tensioning sleeves is realized through an oil pipe, a piezometer is mounted at the tail end of each row of the oil pipes, a punch is inserted into a middle round hole of each hydraulic tensioning sleeve, and an electric push rod is mounted below each punch; the upper discrete die comprises an upper die support, hydraulic tensioning sleeves are mounted on a middle supporting plate of the upper die support, oil supply of each hydraulic tensioning sleeve is realized through an oil pipe, and a piezometer is mounted at the tail end of each row of the oil pipes. Shape adjusting is realized by adopting the electric push rods controlled by a circuit, and the die punches are locked through the hydraulic tensioning sleeves after shape adjusting is completed; the punches is high in bearing capacity, thereby being capable of used for plate forming and part supporting; the whole discrete flexible die is simple in structure and low in manufacturing cost; two implementable schemes are provided for curved surface continuation after forming, and the discrete flexible die is high in efficiency, low in cost and free of environmental pollution.

The present invention relates to a kind of preparation method of the 3D-graphene material that uses biomass resource as carbon source, the steps are as follows: (1) dissolve biomass in aqueous solution, after stirring to make it dissolve, add water-soluble inorganic salt, continue to stir until its Form a uniform solution, titrate the above liquid into an organic solvent to obtain a white solid, and dry it in a vacuum oven to obtain a mixture of biomass and salt; (2) put the substance into a tube furnace for carbonization, and disperse the carbonized sample Filter in water to obtain a black solid, which is a 3D-graphene material. The 3D graphene material prepared by the method of the present invention has good water solubility, large specific surface area, high electrical conductivity, uniform material sheet thickness, about 1-2nm, strong adsorption performance for pollutants in dye wastewater, and good for organic dyes. Methyl violet or methylene blue has strong adsorption properties, has good absorption of near-infrared light and can convert it into heat energy.
