A copper foil surface micro-texture treatment and laminating process for low thermal expansion high-frequency copper-clad plate
PendingCN122279604Aincrease contact areaImprove the anchoring effectThermal dilatationCoated surface
This invention discloses a microtexturing treatment and lamination process for the copper foil surface of a low-thermal-expansion high-frequency copper-clad laminate (CCL). Belonging to the field of CCL manufacturing technology, it solves problems in existing CCL technologies, such as the difficulty in balancing peel strength and high-frequency transmission performance, excessively high coefficient of thermal expansion, easy delamination between layers, and patent conflicts. This invention employs a combined plasma etching and chemical micro-etching process to prepare a honeycomb-like pit-column-protrusion composite microtexture on the resin-coated surface of the substrate copper foil. After modification with a fluorine-containing and aminosilane coupling agent and mixed passivation treatment, a surface-modified copper foil is obtained. This foil is then laminated with a low-thermal-expansion high-frequency prepreg containing linear polyarylamide through a segmented preheating, gradual pressure curing, and slow cooling and depressurization process to prepare the CCL. This invention features a simple process, conforms to industrial practice, exhibits excellent overall performance, effectively avoids patent conflicts, and is suitable for high-end fields such as 5G communication and AI servers.

Hidden type hoisting ring of screw lock prestressed concrete square pile
ActiveCN224338219Uincrease frictionavoid collision riskBulkheads/pilesSafety gearPre stressArchitectural engineering
This utility model discloses a screw-locked prestressed concrete square pile with a concealed lifting ring, relating to the field of building engineering technology. It includes a screw-locked prestressed concrete square pile, a concealed groove, and a telescopic lifting ring. The screw-locked prestressed concrete square pile has a concealed groove, within which a telescopic lifting ring is pre-embedded. The telescopic lifting ring comprises a hooked rod cylinder, a straight rod body, and an arc-shaped rod body. This utility model, by creating a concealed groove on the concrete square pile and pre-embedding the telescopic lifting ring within it, allows the telescopic lifting ring to be manually extended before lifting, partially extending out of the concrete square pile. After lifting, the upper part of the telescopic lifting ring automatically retracts into the lower part under gravity, achieving concealment. After the lifting ring is concealed, the lower surface of the upper pile can directly and tightly fit with the upper surface of the lower pile, enhancing the friction between piles, improving stacking stability, avoiding the collision risk caused by the protrusion of traditional lifting rings, and eliminating the need for wooden supports, thus saving on wooden support costs.

An end-non-cured FRP bar anchoring system and anchoring method
ActiveCN118166969BImprove adhesionImprove the anchoring effectBuilding material handlingBuilding reinforcementsFiber bundleRebar
This invention discloses an end-uncured FRP rebar anchoring system and method. The anchoring system includes FRP rebar, a sleeve, a steel rod, a cap, an end plate, a positioning plate, and grout. The FRP rebar is divided into an uncured fiber bundle segment and a cured portion. The sleeve is an inner conical cylinder with a constant outer diameter and a reduced inner diameter, with a groove at the large-diameter end. During anchoring, one end of the FRP rebar is sequentially passed through the central holes of the end plate and positioning plate, and then exits through the large-diameter port of the sleeve. The uncured fiber bundle of the FRP rebar is then wound around the steel rod, and the end is adhered to the surface of the cured FRP rebar. The steel rod is then placed in the groove at the large-diameter end of the sleeve. Finally, grout is injected into the sleeve, and the cap is closed. Anchoring is completed after high-temperature curing and cooling. This invention performs "soft" and "hard" segmentation treatment on the FRP rebar, bending and winding the FRP rebar around the steel rod and bonding it with the grout, thus reducing the anchor length while anchoring the FRP rebar.
