A capillary aluminum tube capable of high-speed flow of a gallium-based liquid metal containing an oxide layer and a preparation method thereof. The preparation method comprises the following steps: (1) pretreatment of the capillary aluminum tube; (2) electrochemical machining of the inner wall of the capillary aluminum tube (3) Anodizing processing of the inner wall of the capillary aluminum tube; Steps (2) and (3) jointly complete the preparation of the surface microstructure of the capillary aluminum tube, so that the inner wall surface of the capillary aluminum tube forms regular square grooves; (4) Surface modification The lipophilic modification of the inner wall of the capillary aluminum tube is completed, and (5) the surface pre-dipping solution is filled to complete the preparation of the super-smooth capillary aluminum tube. The invention realizes the application of gallium and gallium-based liquid metal in the aluminum-based capillary tube. Due to the existence of the surface oxide layer and the pre-injection liquid layer, the driving power consumption when the liquid metal is driven is effectively reduced, and the gallium-based liquid metal and the capillary are isolated. The direct contact of the aluminum tube prevents the occurrence of embrittlement reaction.

The invention discloses an outer water-cooling and inner thermal-insulating high-pressure and high-temperature expansion joint, which is characterized in that two ends of a corrugated pipe (1) are connected with two pressure bearing ring plates (7), the two pressure bearing ring plates (7) are mounted on the outer side walls of two connection tubes (4) respectively, the outer side end parts of the two connection tubes (4) are connected with respective corresponding flanges (3), water jackets (5) outside the connection tubes (4) are arranged between the pressure bearing ring plates (7) and the flanges (3), the inner side end parts of the two connection tubes (4) are connected with two lining cylinders (14) with partial crossed cylinder bodies, zirconium-containing fiber blanket assemblies (15) are arranged on the outer side walls of the lining cylinders, and corrugated inside clearances of the corrugated pipe (1) are filled with zirconium-containing cellucotton. After an aerodynamic pipeline adopts the expansion joint provided by the invention, the expansion joint has the advantages of no abnormal deformation and flexible and reliable compensation action, stress and moment of main equipment are decreased to the level below the allowable stress value and the allowable moment value, and the equipment and pipelines run stably.

The invention belongs to the technical field of fluorination equipment and discloses an online fluorination device for plastic containers. The online fluorination device for plastic containers includes a fluorination box, a sealed box door installed on the front of the fluorination box, a vacuum pump, and a gas generator. It communicates with the inside of the fluorination tank through the connecting pipe one. The online fluorination device for plastic containers is inserted into the container through the design of the positioning branch pipe and the support wire, and is supported by the container inside the container. The fluorinated reaction gas is released from the positioning branch pipe, and reacts preferentially with the inner wall of the container, and utilizes the impact of the gas The force and the elasticity of the support wire can help the container jump during the air intake process, and the support position of the support wire can be changed to ensure the uniform contact between the fluorinated gas and the inner wall of the container, without blind spots, and to avoid the fluorination effect of the support points of the components in the existing equipment bad question.
