It can also be used as a high and low temperature lubricant between various materials, a lubricant for plastic manufacturing, and a shock-proof damping material for precision machinery and instruments.
NO.04
Product identification method
Take 0.5g of this product, add 0.5ml sulfuric acid and 0.5ml nitric acid, slowly burning, that is, to form a white fiber, and finally leave a white residue.
Take 0.5g of this product, put it in a test tube, heat it on low heat until white smoke appears. Invert the test tube on another test tube containing 0.1% sodium chromic acid and sulfuric acid solution lml, so that white smoke comes into contact with the solution.
Shake the second tube for 10 seconds, heat the water bath for 5 minutes, and the solution will appear purple. The infrared light absorption pattern of this product should be consistent with the control pattern (spectral set 10 figure).
