二、活性炭半成品進(jìn)行活化
  
  活化是在有氧化劑的作用下，對碳化后的材料加熱，以生產(chǎn)活性炭產(chǎn)品。當(dāng)氧化過程的溫度在800-900℃時(shí)，一般用蒸汽或二氧化碳為氧化劑;當(dāng)氧化溫度在600℃以下時(shí)，一般用空氣做氧化劑。對于活化過程所起的作用，目前只有大致的理解。在活化過程中，燒掉了碳化時(shí)吸附的碳?xì)浠衔铮言锌障哆吷系奶細(xì)湓訜?，起了擴(kuò)大孔隙的作用，并把孔隙與孔隙之間燒穿。活化使活性炭變成一種良好的多孔結(jié)構(gòu)，碳化及活化后的晶體片狀結(jié)。

 二是要看蜂窩活性炭產(chǎn)品所產(chǎn)生的氣泡，如果產(chǎn)生的氣泡越多則產(chǎn)品的質(zhì)量就越好。我們可以做一個(gè)小實(shí)驗(yàn)，將一小把蜂窩活性炭產(chǎn)品投入水中，由于水滲透的作用，水會隨之浸入活性炭的孔隙中，以此來讓孔隙中的空氣排出，從而產(chǎn)生一連串的極為小的氣泡，在水中拉出一條細(xì)小的氣泡線，同時(shí)又發(fā)出了茲茲的氣泡聲，看著十分有趣。如果這種現(xiàn)象發(fā)生的很劇烈的話，而且持續(xù)的時(shí)間越長，那么就證明蜂窩活性炭產(chǎn)品的孔隙結(jié)構(gòu)非常發(fā)達(dá)，就是蜂窩活性炭的吸附性越好的表現(xiàn)。
  
  The two is to look at the honeycomb activated carbon products produced by the bubble, if the bubble is more the better the quality of the product. We can do a little experiment, a handful of honeycomb activated carbon products into the water, because the water penetration effect, water will be immersed in the pores of activated carbon, so the pore in the air, resulting in a series of very small bubbles, pulled out a tiny bubbles lines in the water, at the same time also issued Zizi bubble sound, looked very interesting. If this phenomenon is very serious, and the longer the duration, then it is proved that the honeycomb activated carbon product pore structure is very developed, that is, the better adsorption performance of honeycomb activated carbon.
