粉狀(zhuang)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)具體內容是定(ding)量得(de)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)在標準碘(dian)液中吸(xi)附碘(dian)得(de)多(duo)少，一般用來表(biao)(biao)示(shi)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)對小分子雜質(zhi)的(de)(de)(de)吸(xi)附能(neng)力，實際對活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)得(de)性(xing)(xing)(xing)(xing)(xing)能(neng)沒有(you)什(shen)么意(yi)義，也(ye)(ye)就是說(shuo)，碘(dian)值高(gao)得(de)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)不(bu)(bu)見(jian)得(de)就是好，粉狀(zhuang)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)碘(dian)值表(biao)(biao)征活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)略(lve)大(da)于1.0nm微(wei)孔得(de)發(fa)達程(cheng)度。由于碘(dian)分子大(da)小為(wei)0.6nm左右。碘(dian)值就表(biao)(biao)征活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)大(da)于0.6nm的(de)(de)(de)有(you)機物的(de)(de)(de)吸(xi)附量，同時也(ye)(ye)表(biao)(biao)征了大(da)于該1nm活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)孔隙的(de)(de)(de)多(duo)少。粉狀(zhuang)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)碘(dian)值的(de)(de)(de)檢(jian)測(ce)方法粉狀(zhuang)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)作(zuo)為(wei)一種優良的(de)(de)(de)物理、化(hua)學吸(xi)附劑，越來越受到人們的(de)(de)(de)重視。隨著(zhu)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)用途的(de)(de)(de)增(zeng)加，粉狀(zhuang)活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)的(de)(de)(de)檢(jian)測(ce)方法也(ye)(ye)越來越多(duo)。但不(bu)(bu)同的(de)(de)(de)檢(jian)測(ce)方法有(you)可能(neng)會發(fa)生(sheng)不(bu)(bu)同的(de)(de)(de)性(xing)(xing)(xing)(xing)(xing)能(neng)指(zhi)標。

       碘(dian)值一直(zhi)是(shi)評估活(huo)性炭吸附能(neng)力(li)的標準。碘(dian)值越高直(zhi)徑在2.0-8.0mm之間(jian)，大(da)小誤差在5%之間(jian)，顆(ke)粒越細越小果殼活(huo)性炭質量越好(hao)。六個指標教你(ni)區分(fen)果殼活(huo)性炭的好(hao)壞催(cui)化載體活(huo)性炭。

       杏殼(ke)活性(xing)炭比表(biao)面積:

       比表(biao)面(mian)(mian)積是將一克果殼活性炭內部空(kong)間(jian)產開呈現(xian)一個面(mian)(mian)，這個平面(mian)(mian)的(de)面(mian)(mian)積就是果殼活性炭的(de)比表(biao)面(mian)(mian)積，比表(biao)面(mian)(mian)積大(da)的(de)果殼活性炭質量(liang)就越好。

       機(ji)械強度(du)：機(ji)械強度(du)決定了果殼活(huo)性(xing)炭的(de)使用壽命，機(ji)械強度(du)越(yue)高(gao)(gao)，果殼活(huo)性(xing)炭強度(du)就(jiu)越(yue)高(gao)(gao)，質量就(jiu)越(yue)好。

       灰(hui)(hui)分(fen)(fen)(fen):灰(hui)(hui)分(fen)(fen)(fen)主要(yao)是(shi)過客活性(xing)炭燒制后殘留物，灰(hui)(hui)分(fen)(fen)(fen)越低說明果殼活性(xing)炭的燒制過程越規(gui)范，殘留物也就越少。

       決定果(guo)(guo)殼(ke)活性(xing)炭(tan)質量的因素又(you)很多，只有通(tong)過各方面的綜合對比，才能確保果(guo)(guo)殼(ke)活性(xing)炭(tan)的質量。

       粉狀活性炭(tan)的(de)微(wei)孔(kong)(kong)可(ke)以(yi)吸(xi)附低分(fen)子(zi)(zi)量(liang)的(de)氣(qi)體(ti)和(he)(he)溶液中(zhong)(zhong)的(de)小分(fen)子(zi)(zi)，但分(fen)子(zi)(zi)量(liang)較(jiao)(jiao)高(gao)的(de)分(fen)子(zi)(zi)不能進入微(wei)孔(kong)(kong)內，中(zhong)(zhong)孔(kong)(kong)提供進入微(wei)孔(kong)(kong)的(de)通道，本身又能吸(xi)附分(fen)子(zi)(zi)量(liang)較(jiao)(jiao)高(gao)的(de)物質(zhi)，大孔(kong)(kong)則兼有(you)提供通道和(he)(he)吸(xi)附的(de)作用(yong)(yong)。如果(guo)用(yong)(yong)活性炭(tan)吸(xi)附小分(fen)子(zi)(zi)物質(zhi)，例如某些(xie)氣(qi)體(ti)(毒(du)氣(qi)）和(he)(he)低分(fen)子(zi)(zi)量(liang)的(de)有(you)機物，可(ke)以(yi)使用(yong)(yong)微(wei)孔(kong)(kong)較(jiao)(jiao)多的(de)產品(pin)；但如果(guo)要吸(xi)附較(jiao)(jiao)大的(de)分(fen)子(zi)(zi)，則要選用(yong)(yong)有(you)較(jiao)(jiao)多中(zhong)(zhong)孔(kong)(kong)的(de)產品(pin)。
