Embodiment 1
[0039] In this embodiment, the national standard glass bead type A is selected as the evaluation object, and the specific test method is as follows:
[0040]Weigh about 300g of glass beads, and place them at a temperature of 105-110°C for 1 hour to dry. The pore diameters of the sieves are 0.85mm, 0.6mm, 0.3mm, and 0.106mm. Then, put the dried glass beads in the sieve, cover the test sieve cover, and start the vibrating sieve machine. The shaking frequency of the vibrating sieve machine is 290 times / min, the beating frequency is 156 times / min, and the vibration is 5min. Then remove the test sieve from the vibrating sieve machine, weigh the mass of the remaining sample on each sieve and the mass of the sample remaining on the tray after sieving, with an accuracy of 0.1g. If the mesh is blocked by glass beads, it can be brushed out from below with a brush as the remaining sample on the sieve. If the total mass of glass beads in the remaining samples on each test sieve after sie...
Embodiment 2
[0056] The present embodiment selects American standard glass bead type B as evaluation object, and concrete test method is as follows:
[0057] Weigh about 300g of glass beads, and place them at a temperature of 105-110°C for drying for 1 hour. The apertures of the composed screens are 1.18mm, 0.85mm, 0.6mm, 0.425mm, 0.3mm, 0.18mm, 0.15mm . Then, put the dried glass beads in the sieve, cover the test sieve cover, and start the vibrating sieve machine. The shaking frequency of the vibrating sieve machine is 290 times / min, the beating frequency is 156 times / min, and the vibration is 5min. Then remove the test sieve from the vibrating sieve machine, weigh the mass of the remaining sample on each sieve and the mass of the sample remaining on the tray after sieving, with an accuracy of 0.1g. If the mesh is blocked by glass beads, it can be brushed out from below with a brush as the remaining sample on the sieve. If the total mass of glass beads in the remaining samples on each t...
Embodiment 3
[0073] The present embodiment selects American standard glass bead type C as evaluation object, and concrete test method is as follows:
[0074] Weigh about 300g of glass beads, and place them at a temperature of 105-110°C to dry for 1 hour. The pore diameters of the sieves are 1.4mm, 1.18mm, 1.0mm, 0.85mm, 0.71mm, and 0.6mm. Then, put the dried glass beads in the sieve, cover the test sieve cover, and start the vibrating sieve machine. The shaking frequency of the vibrating sieve machine is 290 times / min, the beating frequency is 156 times / min, and the vibration is 5min. Then remove the test sieve from the vibrating sieve machine, weigh the mass of the remaining sample on each sieve and the mass of the sample remaining on the tray after sieving, with an accuracy of 0.1g. If the mesh is blocked by glass beads, it can be brushed out from below with a brush as the remaining sample on the sieve. If the total mass of glass beads in the remaining samples on each test sieve after s...
