GB/T 6609.2 alumina chemical analysis methods and determination of physical performance - Part 2. 300 ℃ and 1000 ℃ mass loss Determination (GB/T 6609.2-2009, ISO 806.2004, MOD) GB/T 6609.23 alumina preparation and storage of chemical analysis methods and determination of physical performance of the sample (GB/T 6609.23-2004, ISO 802. 1976, MOD) --- ISO 3310-3 Test sieves - Technical requirements and testing - Part 3. Electric forming screen

3 PRINCIPLE OF THE METHOD

With acetone, the alumina samples were sieved through a 20μm sieve of electroforming, after 300 ℃ drying to calculate the content on the screen material.

4 Reagents

4.1 acetone. AR. Note. Acetone is flammable, it should be used in the hood. 4.2 Desiccant. phosphorus pentoxide, molecular sieves or activated alumina applicable, silica NA. Warning. phosphorus pentoxide is toxic and should involve the safety instructions on the duration of this substance. 4.3 ethanol. Industrial pure.

5 Instruments

Sieve 5.1. ISO 3310-3 meet the requirements of a sieve, having a diameter of 75mm ~ 150mm, a pore diameter of 20μm mesh sieve electroforming. hole A round of sieve material requires an appropriate grid to maintain sufficient strength. Sieve material shall meet from chemical attack, and in At 110 ℃ no mechanical damage. Grid should tightly strapped to the frame of the screen, in order to prevent the particles from the connection through. Note. Normally there are two suitable mesh, # 317 and # 570, # 570 mesh aperture area of about 17% to # 317 3.5%, which sieve 570 # 317 # efficient but easier than the brittle fracture. 5.2 sieve brush. resistance to acetone, any paint on the brush should be cleaned. Note 1. The stiff brush child is not applicable, it can lead to high results and damage the sieve. Note 2. Black hair brush relatively easy to use, it can clearly be seen whether the brush is attached with aluminum oxide. 5.3 Oven. with air circulation can be controlled 300 ℃ ± 10 ℃. ......
