The invention is used for power generation of the microbiological fuel cell and the organic pollutant in water body deposit removal.

Disclosed is a pressure-sensitive adhesive tape which comprises a base 1 and one or two pressure-sensitive adhesive layers disposed on one or both surfaces thereof, characterized in that either the pressure-sensitive adhesive layer in the case where the base 1 has a pressure-sensitive adhesive layer on only one surface or at least one of the two pressure-sensitive adhesive layers in the case wherethe base 1 has two pressure-sensitive adhesive layers on both surfaces comprises a first pressure-sensitive adhesive layer 2, which is in contact with the base 1, and second pressure-sensitive adhesive regions 3, which are in contact with the first pressure-sensitive adhesive layer 2 and are located on the surface side in the pressure-sensitive adhesive tape and that the first pressure-sensitiveadhesive layer 2 has a higher storage modulus G' than the second pressure-sensitive adhesive regions 3. This pressure-sensitive adhesive tape facilitates positional adjustment and air removal during application and has an excellent waterproof performance after the application.

The invention discloses a method for preserving fresh Spodoptera frugiperda egg masses for multiplying and multiplying Spodoptera spp. Preservation under restricted conditions such as low temperature, while inhibiting the hatching of the eggs of Spodoptera frugiperda, ensured that the egg masses can be used for parasitism by the black egg wasp for a long time, and achieved the purpose of concentrating and multiplying the population of the black egg moth, which is convenient for timely The biological control effect of releasing parasitoid wasps in the field to control night greed in grassland. Its operation process is simple, safe and reliable, and provides a large number of parasitoid wasp sources for the convenient and quick use of the eggs of Spodoptera frugiperda to multiply the black egg wasp of Spodoptera frugiperda and the application of biological control technology for controlling Spodoptera frugiperda.

The invention provides a gluing process for the manufacture of copper-clad laminates. The operation is completed by the cooperation of a fixed frame, a rubber roller, a gluing roller and a dispersion device. The amount of glue is small, so the rotating drive roller only needs to bring a small amount of glue to the surface of the drive roller, but because the resin glue is fluid, it is difficult for the glue to adhere to the surface of the drive roller, which may cause partial transmission The surface of the roller fails to adhere to the resin glue, and the glue is not evenly distributed, so that part of the substrate cannot be glued. The resin glue is fluid after being heated. Due to the low surface temperature of the drive roller, when the drive roller When the surface is in contact with the resin glue solution, part of the resin solution may be cured, which affects the gluing efficiency of the substrate and other issues.

The invention relates to a coating slurry for a lithium battery diaphragm and a coating process. The coating slurry comprises the following components in parts by weight: 35-55 parts of a copolymer emulsion, 25-40 parts of a titanium dioxide dispersion, and 3-6 parts of a dispersant 3-5 parts of chlorinated polypropylene and 1-4 parts of adhesive; the copolymer emulsion is a copolymer emulsion of tetrahydrofuran acrylate and butyl methacrylate; the coating process includes the following steps: S1. dispersing the copolymer emulsion and titanium dioxide Add liquid and chlorinated polypropylene to a magnetic stirrer and stir for 8-10min, then add a dispersant and continue stirring for 45-55min, and finally add an adhesive and stir for 25-35min to obtain a primary slurry for coating; S2. Perform ball milling treatment to obtain the finished slurry; S3. Place the diaphragm on a coating machine, and coat the finished slurry on the surface of the diaphragm at room temperature; S4. Place the diaphragm in an environment of 42-45°C for vacuum drying processing to obtain a coating-modified microporous membrane; S5. winding the coating-modified microporous membrane to obtain a finished product. The coating slurry in the present invention has good adhesion to the separator.

The present invention provides a method for forming a heat-treated conductive film on a passivation-forming light metal, which is to form a conductive film such as silver, copper, tin, etc. on a passivation-forming light metal selected from aluminum, magnesium, and titanium through a base film. A coating method, the base coating is a nickel-phosphorus coating, the base coating is formed by using a nickel-phosphorus electroplating bath containing a prescribed soluble nickel salt, a phosphorus-containing compound, a complexing agent, a surfactant, a buffer, and a brightener, And heat-treating the base coating, or the base coating and the conductive coating under conditions including a low temperature range of 30°C or higher, can strengthen the adhesion of the base coating to the passivation light metal compared to a method without heat treatment. A conductive film is formed on the passivation-forming light metal more firmly.

The invention belongs to the field of painting devices of enamelled wires, and particularly relates to a copper wire painting device for a horizontal high-speed enamelling machine. The copper wire painting device is provided with painting molds and a paint supplying device. The painting molds are used for carrying out multi-channel painting on each row wire, and the paint supplying device supplies paint liquid to the painting molds. The painting molds are horizontally arranged in parallel in the axial direction of mold holes in the molds, and containing boxes for containing paint liquid are arranged on wire inlets of the painting molds at the first painting working procedure and the last painting working procedure, each containing box is provided with a wire inlet end and a wire outlet end, copper wires to be painted pass through the wire inlet end and the wire outlet end of each containing box, the arrangement positions of the wire inlet end and the wire outlet end of each containing box are lower than the maximum containing height position of the paint liquid in the corresponding containing box, and the wire inlet end and the wire outlet end of each containing box are coaxial with the wire inlet of the corresponding painting mold. Due to the fact that the containing boxes are used as preparation painting units of the copper wires, painting stability of the enamelled wires at the painting technological position is effectively ensured, and the good film painting and coating effects of the enamelled wires are ensured.

An adhesive tape is disclosed, which is characterized in that it is an adhesive tape having an adhesive layer on one side or both sides of a substrate 1, an adhesive layer in the case of having an adhesive layer on one side of the substrate 1, or an adhesive layer on one side of the substrate 1. When the base material 1 has adhesive layers on both surfaces, at least one of the two adhesive layers has the first adhesive layer 2 in contact with the base material 1 and the first adhesive layer 2 Next, in the second adhesive region 3 located on the surface side of the adhesive tape, the storage elastic modulus G' of the first adhesive layer 2 is higher than the storage elastic modulus G' of the second adhesive region 3 . This pressure-sensitive adhesive tape is easy to perform position adjustment and air removal at the time of sticking, and is excellent in waterproofness after sticking.
