合成晶種的方法--rubbing

|
完全不懂,誰(shuí)做過(guò)這種播種ZIF-8晶種的方法,求解答,大致用中文讓我明白什么意思也行, ZIF-8 membranes were prepared inside tubular α-alumina supports (0.2 μm pores, US Filter) by secondary seeded growth. Before synthesis, about 1 cm on each end of the supports was glazed (Duncan 1001N) to prevent membrane bypass and to provide a sealing surface for Orings. The permeate area was ~5.1 cm2. The glazed supports were calcined at 900oC for 30 min with controlled heating and cooling rates of 1 oC/min and boiled at 100oC for 1 hr and dried overnight at 100oC. Membranes were prepared by rubbing the inside surface of the support with dry ZIF-8 seeds and outside wrapped with teflon tape. |

通過(guò)二級(jí)種子生長(zhǎng)用ZIF-8膜制備內(nèi)管α型氧化鋁支架(0.2微米毛孔,美國(guó)過(guò)濾器)。合成前,在支撐各端約1cm為 釉面(鄧肯1001N),以防止膜旁路并提供一密封表面為O形圈。滲透面積為~5.1平方厘米。釉面載體煅燒在900℃進(jìn)行30分鐘,受控加熱和1攝氏度/分鐘的冷卻速率和在100℃沸騰1小時(shí),并在100攝氏度下干燥一夜。膜制備通過(guò)摩擦支持體的用干ZIF-8的種子的內(nèi)表面以及用特氟龍膠帶包裹的外表面。 翻譯的不是很地道,樓主在揣摩下 |
