The method comprises the following steps: 1) preparing a mixed solution of plant polyphenols; 2) preparing a mixed solution of polyacryloylmorpholine; 3) flowing the mixed solution of plant polyphenols through a hemodialysis membrane at a constant temperature to obtain a modified plant polyphenol Hemodialysis membrane; 4) At a constant temperature, the above-mentioned polyacryloylmorpholine mixed solution flows through the above-mentioned plant polyphenol modified hemodialysis membrane to obtain a plant polyphenol-polyacryloylmorpholine composite modified hemodialysis membrane. The plant polyphenol-polyacryloylmorpholine composite modified hemodialysis membrane proposed in the embodiment of the present invention is mainly used for hemodialysis, has good biocompatibility, and realizes the purpose of the hemodialysis membrane intervening in oxidative stress.

The invention belongs to the field of machining methods for disk-shaped parts with thin radial plates and thick wheel flanges, and discloses a multi-pass spinning accumulation thickening forming method. The thickening process of the forming method includes multiple passes, and the slot shapes of spinning rollers of different passes are different; the slot of the spinning roller of each pass can bedivided into three parts, and the section of each part is trapezoidal; the second part is located between the first part of the top surface and the second part, and the thickness of the third trapezoid bottom surface of the section of the third part is the finally required thickness of a plate to be machined; the thickness of the first trapezoid top surface of the section of the first part is theinitial thickness of the plate to be machined, and the volumes of the second part and the first part are gradually decreased by increasing the volume of the third part gradually, till the volumes ofthe first part and the second part are decreased to zero; and thus, the process of gradually thickening the plate from inside to outside through the multiple passes is achieved. Through the forming method, the controllable thickening process of the plate is achieved, and the formed plate is uniform in thickness; and the forming quality is high, and the forming process is stable.

The invention discloses a filter bag for filtering and recovering non-ferrous metal dust and a preparation method thereof. The filter bag contains 85% to 95% by weight of microporous composite filter material and the weight loaded on the microporous composite filter material. The adsorption layer with a percentage of 5%-15%, the adsorption layer is a mixture obtained by blending magnetic nano iron oxide, polytetrafluoroethylene dispersion emulsion and dispersant emulsion after curing treatment, and the weight percentage of magnetic nano iron oxide in the mixture is 3%-25%, the weight percentage of polytetrafluoroethylene is 55%-70%, and the balance is the cured product of the dispersant emulsion. The filter bag prepared by the invention has stronger adsorption force for metal dust, effectively shortens the formation time of the powder cake layer, and improves the recovery rate of non-ferrous metals and the effectiveness of cleaning dust; the filter bag of the invention has higher filtration precision and electrical conductivity. It will be significantly improved to obtain excellent anti-static and explosion-proof capabilities.

The invention discloses a micro-nanometer structure TiO2 coating with high hardness and high adhesion force and a preparation method thereof. The thickness of the TiO2 coating is 10mum to 100mum, the crystal phase compositions of TiO2 in the coating are anatase phase and rutile phase, and in addition, the anatase TiO2 accounts for 3 percent to 35 percent of the mass percent of the TiO2 coating. The liquid phase hot spraying coating method and the traditional hot spraying coating method are adopted and are combined, TiO2 liquid materials and powder are simultaneously sent into hot spraying coating flame, compared with the TiO2 coating obtained by the liquid phase hot spraying coating method, the prepared TiO2 coating has the advantages that the microhardness is improved by nearly 10 times, the adhesion force is improved nearly 3 times, the photocatalysis function of the TiO2 coating is favorably realized, important application values are realized, and the micro-nanometer structure TiO2 coating is hopeful to generate huge social and economic benefits.

A controllable intelligent magnetorheological piezoelectric vibration isolation support comprises a lower steel plate and an upper cover plate. Magnetorheological liquid is arranged in four grooves inside the lower steel plate. High-magnetic sliding columns are arranged in the grooves. Excitation coils encircle the high-magnetic sliding columns. Meanwhile, a hydraulic telescopic rod is arranged between every two adjacent high-magnetic sliding columns. The tops of the high-magnetic sliding columns are connected with small friction plates. The small friction plates are connected with a large friction plate. The upper portion of a rubber body filled with magnetorheological gels is connected with the large friction plate, and the lower portion of the rubber body is directly connected with the lower steel plate. The upper portion of the large friction plate is connected with the upper cover plate through four rubber laminates. The large friction plate and the upper cover plate bear force stably through an upper force transmission cushion plate, a lower force transmission cushion plate and a supporting steel body filled with piezoelectric stacks. Rubber cushion layers are stuck to the interiors of the two side walls of the upper cover plate. Pressure sensor modules arranged inside the rubber cushion layers are matched with wireless transmission modules arranged on the two sides of the large friction plate. According to the controllable intelligent magnetorheological piezoelectric vibration isolation support, real-time monitoring is achieved, and the vibration isolation support is controlled actively to reset and has the advantages of quick response and high sensitivity.

The invention discloses a device for separating walnut shells and taking kernels and a method for using the same. The wall is provided with at least two openings communicating with the walnut positioning holes. Driven by the moving mechanism, multiple striking rods pass through the openings corresponding to each striking rod and strike the walnuts arranged in the walnut positioning holes. The two sides of the walnut positioning hole are respectively used to cover the positioning and quantitative feeding slider of the walnut positioning hole, and a collecting device is arranged below the positioning and quantitative feeding slider on one side of the walnut positioning hole, and the collecting device is connected with a blower; the present invention uses a stirring device to carry out Feeding, compact structure, high efficiency and extremely low failure rate. The shape of the discharge hole of the feeding hopper and the through hole in the positioning conveying mechanism adopt the shape of the walnut positioning section, which realizes the automation and controllability of walnut feeding.
