This utility model discloses a subframe bushing plastic-coated inner core with an anti-rotation and anti-slip structure, comprising an inner core and an outer plastic layer; the outer surface of the inner core is provided with multiple vertically arranged anti-rotation protrusions; the anti-rotation protrusions are provided with a crisscrossing fish-scale pattern. This subframe bushing plastic-coated inner core significantly improves the mechanical bonding force with the plastic coating layer by optimizing the surface structure of the metal inner core, thus possessing outstanding advantages in anti-rotation, anti-slip, lightweight, process feasibility, and environmental adaptability. By designing a composite anti-slip texture on the surface of the metal inner core, bidirectional mechanical locking in both axial and circumferential directions is achieved, avoiding the limitations of traditional single-pattern designs.

The invention relates to a novel composite noctilucent material, a preparation method thereof and application of the novel composite noctilucent material in pet garment fabric, and belongs to the technical field of noctilucent materials. The novel composite noctilucent material comprises a substrate layer, and a first packaging layer, a second packaging layer and a surface layer which are sequentially loaded on the surface far away from the substrate layer, the subbase layer is a long-section fiber layer and comprises a silicon resin mixture; the silicon resin mixture comprises silicon resin, a silane coupling agent modified nano oxide and a toughening agent; the first encapsulation layer comprises an aluminate afterglow material, the silicon resin mixture and zirconium oxide; the second encapsulation layer comprises a silicate afterglow material, the silicon resin mixture and cerium oxide; the surface layer comprises the silicone resin mixture, a cured product and short-segment resin fibers. According to the invention, a typical fiber reinforced composite material structure is formed by using the long-section fiber layer as a macroscopic skeleton and the short fiber in the packaging layer as a microcosmic reinforcement, so that cracks or defects caused by stress concentration on brittle luminescent material microcrystals are prevented.

This invention discloses a wear-resistant aluminum alloy power cable and its manufacturing equipment, relating to the field of cable manufacturing technology. A fixed wheel frame is slidably connected to the top of the centrifugal frame via two centrifugal sliding rods. A clamping wheel is rotatably installed inside the fixed wheel frame, and a clamping spring connects the fixed wheel frame to the top of the centrifugal frame. A gas collecting ring box is installed on the outside of the linkage plate, and a sealing ring is rotatably connected to the inside of the gas collecting ring box. Three gas distribution pipes are evenly spaced inside the sealing ring, and a plasma generator is connected in the middle of the gas distribution pipes. When the assembly frame stops rotating, the clamping springs rebound, and the clamping wheels tightly clamp and fix the steel strip, preventing it from loosening and improving the wrapping quality of the steel strip. Compressed air blows out the plasma generated by the plasma generator, which bombards the surface of the wrapped steel strip, forming a micro-uneven structure, allowing the outer sheath to better adhere to the steel strip armor layer, thus improving the quality of the finished cable.
