Preparation of steel substrates before application of paints and related products—Test methods for metallic blast-cleaning abrasives—Part6:Determination of foreign matter

This part is a part of the national standard GB/T 19816 on the sampling and testing of metallic abrasives for blast cleaning. The types of metallic abrasives and the requirements for each type are contained in the various parts of ISO 11124. ISO 11124 and GB/T 19816 are a series of standards on metallic abrasives for blast cleaning. The degree of contamination of all specified abrasives in these two series of standards by foreign impurities. The content of foreign impurities such as oxides, smelting residues, etc. is determined by magnetic separation.

3 Equipment
Except for routine experiments In addition to laboratory instruments and glassware, the following equipment should also be included. 3.1 Balance, weighing accuracy of 0.18
3.2 Magnetic support.
4 Sampling
Take representative samples of the tested products according to the provisions of GT/T19H76, 1-305. 5 Preparation of products
If it is believed or suspected that there is moisture, the sample should be dried before the test. 6 Steps
Take the sample for determination by the indirect method.
6.1 Use a balance (3.1) to take (100 ± 3.)g of the sample. 6.2 Put 6.3 Place the iron (3.2) on a piece of paper with a small amount of sample (about 2) and pass it through the surface of the paper to remove the gold particles. Keep the residue. III: All gold particles are absorbed by the pressure. 6.4 Repeat the steps in 6.2 and 6.3 until all the sample is separated. During the use of the magnet, it should be kept away from the environment to prevent the accumulation of gold particles.
GB/T19816.6—2005/1SO11125-6:19936.5 When all the obvious gold particles are separated from the sample, thinly place the residue on the paper. In the paper soil, the bacteria can be used to teach the full from its surface, remove all the drug properties,
5.5 stable will remain, calculate the percentage of foreign impurities. 7 Test report
