1 Scope

This section GB/T 21782 specifies the method of screening method for the determination of particle size distribution of the powder coating. This method can distinguish between 32μm ~ The particle size within the range of 300μm. This method can also be used as a simplified procedure to use that only a single sieves sieve residue (pass/fail) test.

3 Instrument

3.1 Test sieves. a 200mm diameter cylindrical screen surface. Test sieve sieve sieve wall and should be metallic. Mesh aperture range should be in between 32μm ~ 300μm, and in line with GB/T 6005-1997 (see Appendix A) requirements. Test sieves should be transparent cover. Mesh choice will depend on the actual situation. If you know the size distribution of the sample, then only with compatible size range Test sieve. For certain purposes, but also allows selection of test sieves with the agreed manner to obtain sufficient data, which agreed upon by the two parties concerned. 3.2 airflow screening device (see Figure 1). composed of a cylindrical drum with a test sieve (3.1) in.

1 air screen

At the bottom of the barrel (connected fan) should have an outlet and an inlet for air flow in and out. Air inlet and a speed 20r/min ~ 25r/min jet device is connected, by a sharp slit-like nozzle configuration, this should be close to the screen and export longitudinally mounted in the bottom of the screen GB/T 21782.1-2008/ISO 8130-1.1992 ......
