This application relates to a corrosion inhibitor for coolants, a method for preparing the same, and a coolant. The corrosion inhibitor comprises: 1 wt% to 5 wt% fatty acid, 0.05 wt% to 0.5 wt% aromatic acid, 0.1 wt% to 1.0 wt% benzotriazole derivative, and 0.1 wt% to 1.0 wt% additives. The benzotriazole derivative has the structural formula shown in Formula I below. In Formula I, R1 to R4 are each independently selected from at least one of fluorine, substituted or unsubstituted C1 to C5 alkyl groups. When substituted, the substituent is selected from fluorine. The corrosion inhibitor for coolants provided in this application, comprising a benzotriazole derivative, can form stable coordination bonds with metal ions in the coolant, thereby reducing the flow resistance of the coolant while improving its corrosion inhibition performance.

This invention discloses a method for preparing high-density, high-purity polycrystalline barite polymers under hot isostatic pressing conditions, wherein barite sample powder is compacted and sealed to a vacuum degree of 10. –3 The sample was placed in a steel cladding with dimensions of 55.89 mm outer diameter × 88.76 mm height × 3 mm wall thickness. The cladding was then placed inside the graphite furnace cylinder of a hot isostatic pressure vessel and sealed with a graphite cap. Using argon as the pressure transfer medium, a multi-gradient cylinder heating and pressurization method was employed to raise the temperature inside the sample chamber to 950 °C and the pressure to 112.5 MPa. This pressure and temperature were maintained for 6.0 hours. A multi-gradient cylinder cooling and depressurization method was then used to lower the temperature inside the sample chamber to 178 °C and the pressure to 71.1 MPa. The pressure was then released and the sample was cooled to room temperature to obtain a polycrystalline barite polymer. This method filled the technical gap in the preparation of bulk sulfate experimental samples of high-density polycrystalline barite polymers under high temperature and high pressure conditions.

This application relates to a rapid cooling and transfer device for MLCCs. The rapid cooling and transfer device for MLCCs described in this application includes a receiving pipe and an air blowing pipe. One end of the receiving pipe forms a receiving port, and the other end forms a discharge port. The air blowing pipe extends into the receiving pipe from the discharge port, and its end is closed. A discharge channel for MLCC movement is formed between the outer wall of the air blowing pipe and the inner wall of the receiving pipe. Multiple air blowing holes are provided around the periphery of the air blowing pipe, connecting an external air source to the discharge channel. The rapid cooling and transfer device for MLCCs described in this application enables high-temperature MLCCs to simultaneously undergo oxidation protection and rapid cooling during the transfer process, solving the two major bottlenecks of oxidation failure and low cooling efficiency in traditional transfer processes, and improving the performance of the processed MLCCs.
