测定石棉纤维被强酸或强碱作用后的重量损失,比较其耐化学腐蚀性强弱,是评石棉矿物质量和决定其工业用途的重要指标,研究酸碱溶液对样品的腐蚀量,是评价其耐酸碱性能的主要方法。四川石棉矿和新康石棉矿是超基性岩型纤维蛇纹石石棉矿山。对两矿产出的石棉,前人也作过一些酸碱腐蚀试验,其中很多样品的腐蚀量均比一般矿区偏高,其原因一直未能搞明。为了搞清两矿纤维蛇纹石石棉的腐蚀性能及其影响因素,我们在两矿按不同采场取了
Determination of asbestos fibers by strong acid or alkali after the weight loss, compared with the strength of chemical resistance, is to assess the quality of asbestos minerals and determine their industrial use of an important indicator of the acid-base solution of the sample to assess the amount of corrosion is to evaluate its Acid and alkali resistance of the main methods. Sichuan asbestos ore and Xin Kang asbestos ore is an ultrabasic rock type fiber serpentine asbestos mine. Asbestos from the two mines, some predecessors also made some acid-base corrosion tests, of which many samples of corrosion are higher than the average mining area, the reason has been unable to figure out. In order to find out the corrosive properties of the two mineral fiber serpentine asbestos and its influencing factors, we took two mines according to different stopes
