This invention relates to the field of zinc alloy surface modification technology, and particularly to a corrosion-resistant medical zinc alloy, its preparation method, and its applications. The preparation method includes the following steps: weighing raw materials according to the chemical composition of the zinc alloy; cleaning the surface of the raw materials; smelting, refining, and casting to obtain an ingot; subjecting the ingot to equal-channel angular extrusion deformation to obtain an extruded zinc alloy; performing high-energy ion implantation on the zinc alloy to obtain a nitrogen-ion-implanted zinc alloy; and preparing a coating on the surface of the nitrogen-ion-implanted zinc alloy to obtain the final product. This invention achieves a high-adhesion, dense, and uniform deposition effect on the alloy surface through the synergistic control of "equal-channel angular extrusion + high-energy nitrogen ion implantation + biomimetic coating deposition," solving the problem of severe galvanic corrosion at localized sites in existing zinc alloys under corrosive environments. Simultaneously, the dense deposition layer helps inhibit rapid dissolution of the zinc alloy surface, significantly reducing the corrosion rate of the zinc alloy in corrosive environments.

The invention provides a hydrophilic polyphenylene sulfide fiber, which relates to the field of monofilaments and comprises a core layer made of polyphenylene sulfide and a hydrophilic film, the hydrophilic film covers the outer side of the core layer. The hydrophilic polyphenylene sulfide fiber provided by the invention can solve the problem that the application of the PPS on special protective clothing, industrial filter bags and membranes with specific purposes is limited due to poor hydrophilic performance of the PPS in the prior art, and realizes improvement of the hydrophilic performance of the PPS.

The utility model belongs to the technical field of adhesive tape production, and particularly relates to an adhesive tape edge dust removal winding mechanism which comprises a fixed base, a supporting plate, a first guide roller, a dust removal assembly, a second guide roller, a third guide roller, a controller, a cutting mechanism and a collecting roller. When the dust removal device is used, dust, impurities and the like on the adhesive tape can be blown away through air masses generated by the two high-frequency ion tuyeres arranged on the two-way screw rod in the process that the adhesive tape is conveyed from the first guide roller to the second guide roller by the arranged dust removal assembly, and meanwhile the dust and the impurities on the adhesive tape can be removed through a large number of generated air masses with positive and negative charges. Positive and negative charges on the edge of the adhesive tape passing through the ion radiation area are neutralized, the purpose of eliminating static electricity is achieved, a good dust removal effect is achieved, and the edge of the adhesive tape subjected to dust removal is not prone to absorbing dust again.

This utility model discloses a konjac planting fertilizer applicator, including a moving component for movable support and rotating soil turning. The top of the moving component is equipped with a conveying component for evenly distributing fertilizer, and the bottom of the conveying component is equipped with a guiding component for distributing fertilizer. Two symmetrically arranged burying components at the bottom of the guiding component are used to bury the fertilizer deep into the soil. In this utility model, a cylinder drives a pneumatic hammer to push the fertilizer, allowing it to reach deep into the soil for better root absorption. The design of the spiral rotating rod distributing fertilizer ensures a stable fertilizer output and breaks up lumps to prevent agglomeration. A baffle plate swings left and right to distribute the fertilizer, simultaneously fertilizing two rows of soil, saving manpower and improving work efficiency. The clamps can be moved to move the pushing tube according to the spacing between the two rows of konjac plants, adjusting the fertilizer's falling position, making the device highly practical.
