一、可反复使用的黄金管 为了防止高压釜腐蚀及容器腐蚀而污染实验溶液,人们常使用比高压釜腔体尺寸略小的黄金管(或铂管、银管)作衬套,或将实验样品焊封在小金管中。前者由于容器体积较大需耗费较大量贵金属,同时因高压釜封口处的剪切力使衬套容易损坏,后者,由于弧焊或气焊使金管每次实验后至少要短5—8毫米,因而两、三次后金管就不能持续使用(管太短、内装水溶液而无法焊封)。为了延长金管使用寿命,
A reusable gold tube In order to prevent the autoclave corrosion and container corrosion and contamination of the test solution, people often use slightly smaller than the size of the autoclave chamber tube of gold (or platinum tube, silver tube) for bushing, or experiment The sample is welded in a small gold tube. The former due to the larger container requires a larger amount of precious metals, while the autoclave seal at the shear force so that the liner easily damaged, the latter, due to arc welding or gas welding so that after each experiment at least 5-8 mm short, Therefore, two or three times after the gold tube can not be used continuously (tube is too short, built-in solution and can not be welded). In order to extend the life of the gold tube,
