The invention discloses an easy-to-tear cover tape, comprising a wax layer, an antistatic layer, a base material layer and a heat-sealing layer sequentially arranged from top to bottom. On both sides of the bottom of the material layer, the top of the wax layer is provided with several pressing blocks, the pressing blocks are protruding, and the strength of the pressing blocks is greater than the maximum strength of the wax layer, the antistatic layer and the substrate layer , The two heat-sealing layers are respectively provided with extruding blocks facing each other, the extruding blocks are arranged obliquely, and the upper end thereof is closer to the center line of the base material layer. When tearing off the cover tape, you can press the pressing block first, so that the pressing area can sag. At this time, the air pressure between the cover tape and the carrier tape will increase, which can push the extrusion block, which is equivalent to giving the extrusion block an oblique upward movement. The force is on the inner edge of the heat-sealing layer, which weakens the connection force between the heat-sealing layer and the carrier tape. With the external pulling force, the cover tape can be quickly torn. The invention also discloses a preparation method using the above cover tape.

The invention discloses equipment for decomposing skin into fibers in water. The equipment for decomposing skin into fibers in water comprises a first cylinder and a second cylinder which are the same in diameter, wherein the two cylinders are vertically parallel, the surface of an external circle is close to or is arranged on a framework in a tangent mode, the lower portion of the second cylinder is arranged at one side of a water storage tank, the water storage tank is connected with the framework, a work roller close to and parallel with the first cylinder is arranged at the left side of the first cylinder, a first hair removing roller, a second hair removing roller and a third hair removing roller are arranged at the left side of the work roller, the upper portion of the right side of the first cylinder and the upper portion of the right side of the second cylinder respectively, a circulating water filtering curtain is arranged at the lower end of the second hair removing roller and the lower end of the third hair removing roller, circulating water pressing felt is arranged at the lower portion of the right end of the circulating water filtering curtain, a pair of squeeze rollers are arranged at the right portion of the circulating water pressing felt, and a material receiving box is arranged at the right end of the circulating water pressing felt. By means of the equipment for decomposing skin into fibers in water, a large piece of skin can be rapidly torn off into small pieces of skin or skin fibers through the two large cylinders, the work roller and the hair removing rollers.

The invention discloses a local sandblasting method for a part, which comprises the following steps: step 1: paste a detachable layer on the part that does not need sandblasting; step 2: apply a solidified layer on the outside of the detachable layer; step 3: put Apply the cured layer for natural air drying and curing; after the cured layer is cured, the disassembly layer is in close contact with the parts under the force of the cured layer, and then sandblasting and shot blasting are performed. The strength of the cured layer does not require spraying on the parts. Sand and shot blasting parts are protected; after sand blasting and shot blasting, the disassembly and assembly of the disassembly layer will directly drive the solidified layer to separate from the parts, which solves the problem of using AB glue and other glues on the parts that do not need sandblasting. It takes time and effort to protect and remove the adhesive layer, and it is easy to wear the surface of the part.

The invention relates to a nano-drug delivery system and a preparation method of a double-responsive anti-tumor drug-carrying drug delivery system for tumor treatment. Sodium alginate modified with 11‑mercaptoundecanoic acid (MUA) was used as the backbone to make CaCO 3 Co-precipitate with anti-tumor drugs on the sodium alginate skeleton, and use ultrasonic vibration to promote the cross-linking of sulfhydryl groups on the modified sodium alginate to prepare pH and redox dual-responsive nano-drug delivery carriers. The present invention proves that the CaCO-based 3 The nanoparticles have good tumor selectivity and the ability to regulate the pH of tumor cells, which can reduce the toxic and side effects on normal cells and the body while killing tumor cells. The nano drug delivery carrier provided by the invention is expected to be used for tumor treatment, and has a good application prospect in the field of biomedicine.

A method for controlling the floor drum of a roadway by pulse operation, in which a row of obliquely arranged drill holes are respectively arranged at a certain interval at the junctions between the sides of the roadway and the floor on the left and right sides of the roadway; ; Obtain the pressure and displacement information data of deep rock formations at different depths in turn until the entire drilling process is completed; the data acquisition instrument can be used for the later floor according to the obtained pressure and displacement information data in the drilling, combined with the compression deformation. Formulate reasonable parameters for fracturing; use the electric pulse device to perform fracturing operations on the drilled holes on the floor of the roadway; observe the range of shock wave fracturing, and after the expected effect is achieved, take out the electric pulse device and carry out the impact operation of the next adjacent drilling hole , until the fracturing operation of the entire roadway floor is completed; the drilling and fracturing operation on the other side of the roadway floor is completed; and the grouting bolt reinforcement is performed later. This method has high detection accuracy, fast bottom cutting speed and good repair effect.
