1. Is mandatory calibration required for argon gas cylinder flow meters used in welding?
Yes. According to the verification regulations for flow meters, it is necessary to conduct mandatory metrological identification for argon gas cylinder flow meters used in welding. Argon gas is used for inflating light bulbs and for arc welding of stainless steel, magnesium, aluminum, etc. with infiltration, also known as "Tan Sunji argon arc welding". Kaicong
2. What equipment is needed to prepare rubidium sulfide
Core equipment such as reaction vessels, heating equipment, gas supply control equipment, grinding equipment, and vacuum equipment are needed to prepare rubidium sulfide Reaction vessel: Generally, quartz tubes or specially designed metal reaction vessels are used to provide a sealed space for chemical reactions to occur. Quartz tubes have stable chemical properties and can withstand certain temperatures and pressures; Metal reaction vessels tend to have better strength and sealing performance compared to banquet stools. Heating equipment: commonly used muffle furnaces and tube furnaces are used to provide the required high temperature conditions for the reaction. Muffle furnace can accurately control temperature and adapt to various heating reactions; Tube furnaces are more suitable for conducting reactions in specific atmospheres. Gas supply and control equipment includes gas cylinders and gas flow meters. During the preparation process, inert gases such as argon are usually required to protect the reaction system and prevent rubidium from being oxidized. Gas steel celery travel bottles are used to store protective gases, and flow meters can accurately control the flow rate of gases. Grinding equ
