摘要： Featured is a refrigerant injection device which is particularly suitable for use in a refrigerant destruction facility using an incinerator. Such an injection device includes a storage device which stores the refrigerant and a decompressor fluidly coupled to the storage device. The injection device further includes two flow meters and a cutoff-valve that are fluidly coupled to the decompressor. The cutoff valve is configured to cut off the injection of refrigerant. The injection device further includes bypass flow members that are fluidly coupled to the two flow meters. The bypass flow members and flow meters are configured and arranged to selectively measure the flow rate and to perform flow meter calibration without stopping the feeding of refrigerant to the injection device.

摘要： The present disclosure relates to a silver powder preparation method comprising: a silver powder preparation step of preparing a silver salt, which comprises silver ions, and then reducing the silver ion so as to precipitate silver particles; a silver powder recovery step of separating silver particles from an aqueous solution or a slurry, which comprises the precipitated silver particles, and then washing and drying same to recover silver powder; and a silver powder coating step of injecting a pH adjuster into the recovered silver powder to adjust the pH, and then injecting a coating agent to coat after the pH adjustment. The pH adjuster is used in the silver powder coating step to adjust the pH, and thus, when silver power is used in a conductive paste, as the rate of change in viscosity over time is low, a conductive paste having excellent viscosity stability can be provided.
