Just got into the subject group, the coach gave you a set of keys: "go get that big iron cabinet up to 900 degrees and stay warm for two hours."
Newman: isn't this an industrial oven
As a result, the furnace door was opened, cracks were broken; or the gas went wrong, triggering the alarm jump; and, worse, the program was directly powdered after the sample... Don't laugh, 90 per cent of the new researcher was caught up in high-temperature heat treatment。
Today's article is not about complex thermodynamics, but about the types of high-temperature equipment that really go on every day in the university lab. Students involved in materials, chemistry, ceramics and new energy sources are advised to collect them before they go on board. We can keep the equipment, the data, the safety
Muffle furnace - laboratory's basic refinery
Tube furnace - "climate control" primer
️ vacuum / acoustic blast - high level
(c) high-temperature equipment, “surviving” sop (preliminary to a new man on board), looks at the atmosphere selection furnace: air/inertity/recession/vacuity, wrong direct destruction sample + injury equipment. Materials selection packagings: gon yu is 1,600°c but afraid of strong alkaline, quartz is afraid of hydroflonic acid and sudden cold, and graphite burns ash in air. Temperature is more important than warming: natural cooling is the safest and forced cooling is limited to specific equipment. Cold = fragmentation = end of life. Record! Record! Record! The missing data can be reworked and the equipment blew up to write review + pay. First emergency response: odor/acoustic/negative/super-temperature? Don't panic! Just shoot the stop button, turn off the power and evacuate the ventilation. Don't open the panel
The last sentence is true
High-temperature thermal treatment equipment is not “large kitchen appliances”, but “core reaction module” in the scientific chain. It knows no one but the parameters, and does not turn back, but leaves marks. Use it, good data, good graduation; use it wrong, do it the wrong way, do it the wrong way, and it's a security accident。
Which one of your group's most used? The hottest, cooling, air-tightening pits? Welcome to the review area to share a “laboratory history of blood and tears” and, if there is a need to purchase laboratory high-temperature thermal treatment equipment, find a matchable microenrichment
