MH-300T粉體真密度專用比重計MH-300T Hydrometer
適用于:多孔性顆粒、水泥業、防火材料、石材業、粉末理論真密度研究實驗室
值。
測試條件:
浸液法中,選擇不溶解試樣面易潤濕試樣顆粒表面的液體是十分重要的。
對于陶瓷原料如長石,石英和陶瓷制品一般可用蒸餾水作為液體介質。
對可能起作用的材料如水泥則可用煤油或二甲笨等有機液體介質。
對無機粉體一般多選用有機溶劑。
當粉末完全浸入液體中,必須完全排除其氣泡,才能確定其所排除的體積。
用瓷研缽研磨成粉末并通過240目標準篩,將粉樣裝入稱量瓶中,放入 105℃紅外線水份計內烘干,取出,稍冷,放人干燥器內冷卻到室。
超細粉體:根據1773年Bort.M.W.研究,比重瓶法不適應粒度小于5um的超細粉體。

MH-300T powder true density special hydrometer MH-300T Hydrometer
Suitable for: porous particles, cement industry, fireproof material, stone powder true density, theory research laboratory
Value.
Test conditions:
Immersion method, choose not to dissolve the samplesurface to surface wetting sample particles in the liquid isvery important.
For the ceramic raw materials such as feldspar, quartz and ceramic products commonly used distilled water asliquid medium.
On may play a role of materials such as cement usedkerosene or two toluene and other organic liquid medium.
The inorganic powder commonly used organic solvents.
When the powder was completely immersed in the liquid,the bubbles must be completely ruled out, in order to determine the excluded volume.
Powder and through 240 mesh sieve into a porcelain mortar grinding, the powder into the weighing bottle, put in 105 ℃ infrared moisture meter in drying, remove,slightly cold, people put the dryer is cooled to the room.
Superfine powder: according to a 1773 Bort.M.W. study,Pycnometer method can not meet the superfine powderparticle size of less than 5um.
