The invention relates to the technical field of recycled asphalt, and particularly discloses a high-temperature-resistant large-dosage RAP recycled asphalt mixture and a gradient activation preparation method thereof, and the recycled asphalt mixture comprises the following components in parts by weight: 70-90 parts of an RAP material, 5-26 parts of a new aggregate, 4-5 parts of SBS modified asphalt and 0.04-0.05 part of a composite regenerant. The composite regenerant and the bio-oil-based regenerant provided by the invention can recover the flexibility of the aged asphalt; after the silane coupling agent is hydrolyzed, silicon hydroxyl (Si-OH) formed by the silane coupling agent and the bio-oil-based regenerant can be bonded with hydroxyl (Si-O-Si bond) on the surface of the aggregate to form a bonded network, so that the interface adhesion strength is improved, the interface slippage is reduced, the skeleton of the mixture is more stable, the stripping resistance of the interface is enhanced, the dynamic stability and the water stability are improved, and the service life of the mixture is prolonged. And after the recycling agent recovers the flexibility of the asphalt, a bonding network formed by the silane coupling agent endows the recycled asphalt mixture with a high-elasticity characteristic, and the risk of fatigue cracking is reduced.

The application provides a formation method of a nickel-hydrogen battery and a nickel-hydrogen battery formed by the method. The formation method of the nickel-hydrogen battery comprises the following steps: performing normal-temperature activation treatment on a nickel-hydrogen battery primary product to obtain a first-stage nickel-hydrogen battery; performing first heating activation treatment on the first-stage nickel-hydrogen battery to obtain a second-stage nickel-hydrogen battery; performing charging formation on the second-stage nickel-hydrogen battery to obtain a third-stage nickel-hydrogen battery; and performing second heating aging treatment on the third-stage nickel-hydrogen battery to obtain the nickel-hydrogen battery. The pre-charging and 3-4 charging and discharging formation processes are reduced, the charging formation is directly performed after the normal-temperature activation and the heating activation, the charging and discharging is not required to be repeatedly performed for multiple times, and then the heating aging is performed. Compared with the prior art, the formation method of the nickel-hydrogen battery in the application greatly reduces the equipment investment and the power consumption, simplifies the production process, reduces the production period, and improves the production efficiency under the condition that the normal formation effect of the nickel-hydrogen battery is achieved.

This invention belongs to the field of formaldehyde removal technology, specifically a formaldehyde removal agent quantitative release device, comprising a shell structure; the shell has an inner liner connected to it, which together with the inner wall of the shell forms a sandwich space for diverting the incoming formaldehyde removal agent; the inner sidewall of the inner liner is evenly distributed with multiple atomizing nozzles; in this invention, a liquid pump accurately delivers formaldehyde removal agent mixed with a photocatalyst, which is atomized by the atomizing nozzles and flows to the diversion pipe under the drive of the internal swirling flow, and the first fin rotates to expand the diffusion range and accelerate the diffusion speed, and works with the first lamp to activate the photocatalyst, achieving full mixing of the agent with the air, enhancing the formaldehyde removal effect; the various functional components achieve coordinated action through mechanical linkage, reducing dependence on additional power sources, with a compact structure and good operational coordination; the overall equipment forms a highly efficient and coordinated purification system in terms of dust removal, formaldehyde removal, photocatalytic activation, and agent diffusion.
