Introduction to standards:

This part is a part of the national standard GB/T19816 on sampling and testing of metal abrasives for blast cleaning. The types of metal abrasives and the requirements for each type are included in the various parts of ISO 11124. The ISO11124 and GB/T19816 series are a set of closely related standards for metal abrasives for blast cleaning. Information about all parts of these two series of standards can be found in Appendix A. This part of GB/T19816 specifies the method for determining the apparent density of metal abrasives for blast cleaning. The purpose of the test is to confirm the integrity of the metal abrasive. Internal shrinkage or hollow particles will reduce the apparent density.

Test methods for metal abrasives for blast cleaning Part 4: Determination of apparent density
This part is about the sampling and testing of metal abrasives for blast cleaning This part of GB/T 11686 specifies the method for determining the metal abrasive properties of blast cleaning materials. Particles with internal shrinkage or hollowness will reduce the apparent density. 2 Normative reference documents || tt || The clauses in the following documents become clauses of this part through reference to this part of GB/T 11686.

Add about 1m 7.3 Add the static water or the water from the manufacturer (2.1) into the pycnometer until it is completely full. Then shake the pycnometer gently to remove the air attached to the sample. After adding the water, pour out the remaining water through the paper tube. Carefully lower the outside of the pycnometer. Make sure there is no air in the pycnometer. Then weigh the contents of the pycnometer. 7.4 Empty the pycnometer and let the sample flow for ten seconds. Next, remove the traces of the loading material. Then keep the water or remove the water, and keep the car in a cool and dry place. According to the following, the weight of the bottle is higher than the weight of the car!). Note: Try not to have direct contact with the bottle to prevent it from being treated. The bottle, material and the original should be kept in the same room as much as possible. 8 Conclusion
The unit of the measured product density is expressed in dry grams per cubic meter (kg/m3), and the formula (1) is used for calculation:
px - (mm *p × 1ce
is the average value of the effective mass of the test bottle and the sample, in grams (g); the value of the pressure of the test bottle, the sample and the water, in grams (g); the mass of the water at the test temperature, in kg/m3 (kg/cm3). If the difference between the two test results exceeds 13)g/ml, repeat the operation according to the steps in the first chapter. Calculate the average time between the two effective test results.
