This invention belongs to the field of micro-coating protection and discloses an organosilicon aerosol coating for waterproofing precision instruments and its preparation method. The organosilicon aerosol coating comprises, by weight, 4-6 parts of fluorinated organosilicon, 2-3 parts of organosilicon-acrylate resin, 30-40 parts of a first solvent, 20-30 parts of a second solvent, 1-1.5 parts of a release agent, 0.5-1 parts of a leveling agent, and a certain amount of propellant. This invention uses a first solvent and a second solvent with different volatility properties to improve the self-leveling and film-forming quality of the microfilm after spraying, reducing surface micropore defects caused by excessive evaporation and forming a good waterproof layer. Through the synergistic effect of fluorinated organosilicon and organosilicon-acrylate resin as film-forming materials, the waterproof coating formed with the release agent and leveling agent possesses both long-lasting waterproofing and peelability. When used for the protection of precision instruments, the coating can be peeled off after a certain protection period without leaving residual pollution on the instrument surface.

The present application provides a sunlight-resistant colored electrochemical energy storage fabric based on recycled cotton powder and a preparation method thereof, belonging to the technical fields of flexible electronic textiles and electrochemical energy storage. The preparation method first deposits a TiO2 film on the recycled cotton powder by ALD technology, and then performs mild hydrothermal synthesis to obtain a TMOs@TiO2@CP composite powder with a three-layer nested structure. Among them, the TiO2 film protects the internal recycled cotton powder from erosion during the hydrothermal reaction and is tightly combined with the TMOs functional layer through Ti-O-TM covalent bonds, improving the structural stability and interfacial bonding force of the composite powder. The present application uses the inherent color characteristics of different transition metal oxides to replace traditional black carbon-based materials, endowing the energy storage fabric with rich color choices and meeting the aesthetic and design requirements of high-end textiles. The process route of the present application avoids the damage to the inherent flexibility and structure of cotton fabrics by drastic means such as high-temperature carbonization.

This utility model relates to the field of surface treatment technology for cast iron parts, and discloses a surface treatment device for cast iron parts, including a base. Two support rods are fixedly connected to the top of the base. A centering mechanism is provided on the outer adjacent side of the two support rods. Cleaning mechanisms are provided on both outer sides of the two support rods. A grinding mechanism is provided on the top of the base. A placement plate is fixedly connected to the top of the centering mechanism. The centering mechanism includes a sliding plate, which is slidably connected to the outer adjacent side of the two support rods. Sliding grooves are formed inside the two support rods. In this utility model, the support plate, support block, and rotating rod are linked by a telescopic rod, enabling the two centering frames to accurately clamp the cast iron parts, improving centering accuracy and stability, and effectively preventing the cast iron parts from shifting during grinding. The sliding rod and extension rod in the extension assembly can be flexibly adjusted according to the height of the cast iron parts.

The application relates to a photovoltaic frame, which comprises a first frame, a second frame, and a corner code. The first frame comprises a first corner code mounting part. The second frame comprises a second corner code mounting part. The corner code comprises a first mounting part, a second mounting part, and a first photovoltaic fixing part. The inner wall of the first corner code mounting part is entirely covered with a first glue layer. The second mounting part comprises a buckle sleeve, a connecting column, and a second photovoltaic fixing part. The inner wall of the second corner code mounting part is entirely covered with a second glue layer. The connecting column is inserted into the second corner code mounting part. The first photovoltaic fixing part comprises a first connecting surface. The plane of the first connecting surface and the first direction form a first included angle. The second photovoltaic fixing part comprises a second connecting surface. The plane of the second connecting surface and the first direction form a second included angle. The second mounting part is connected with the first mounting part to make the first connecting surface and the second connecting surface fit together. Water vapor can be prevented from entering the inside of the photovoltaic frame, and the waterproof effect is improved.

This application relates to the technical field of marine equipment, and in particular to a marine anchor chain cleaning device, which includes a cleaning tank installed at the anchor winch location and a cleaning device installed inside the cleaning tank. The cleaning tank is filled with a cleaning fluid for cleaning anchor chains. The cleaning device includes a brush assembly installed inside the cleaning tank. The anchor chain to be cleaned passes through the brush assembly and is immersed in the cleaning fluid in the cleaning tank. This application has the effect of improving the ability to clean anchor chains.

This utility model discloses a double-locking anti-loosening power connector, including a plug, one end of which is connected to a connector base. Both sides of the plug are provided with elastic latches. A socket panel is fixedly connected to one side of the connector base. The socket panel has a semi-circular protrusion, and a protruding ring is fixedly connected to the socket panel. A locking groove is formed between the connector base and the protruding ring. The application of springs in this utility model not only provides necessary cushioning for the electrodes but also ensures tight contact between the electrodes and their corresponding interfaces. When the connector is subjected to external impact or vibration, the springs can effectively absorb these external forces, preventing electrode damage or displacement caused by direct impact, greatly improving the durability and stability of the device.
