铂铑丝的含量:铂占80～90%,铑占10～20%,主要用于测温热电偶材料及冶炼厂的高温炉温传感显示材料。使用时间长或断丝,就失去了作用,成为可再生资源。我们把它回收,送到有关厂家进行分离提纯成纯铂、纯铑。我们从现有条件出发,反复试验,摸索了一些简便的鉴别方法,归纳有五种:一、外观法鉴别铂与铂铑丝。热电偶有二根金属丝构成。软的为铂,硬的是铂铑丝。二、火烧法:用打火机烧红一部分丝,冷却后,擦净丝上的灰黑色,与未烧的丝比较,一模
Platinum and rhodium wire content: platinum accounted for 80 to 90%, rhodium accounted for 10 to 20%, mainly used for temperature measurement thermocouple materials and smelting furnace temperature sensor display materials. Use a long time or broken wire, it lost its role as a renewable resource. We take it back, sent to the manufacturers for separation and purification into pure platinum, pure rhodium. We start from the existing conditions, repeated testing, exploring some simple identification methods, summarized in five ways: First, the appearance of platinum and platinum identification of platinum wire. Thermocouple has two wires. Soft for platinum, hard is platinum rhodium wire. Second, the fire method: with a lighter red part of the roasted silk, after cooling, wiping the gray on the black wire, and not burning silk, a mold
