粉(fen)(fen)狀活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)具體內容是定量(liang)得(de)(de)活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)在標準碘(dian)液(ye)中吸(xi)附(fu)(fu)(fu)碘(dian)得(de)(de)多(duo)少，一般用來(lai)(lai)(lai)表示活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)對小(xiao)分(fen)子雜質的(de)(de)吸(xi)附(fu)(fu)(fu)能力(li)，實際對活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)得(de)(de)性(xing)(xing)(xing)(xing)(xing)能沒有(you)什么意義，也(ye)就(jiu)是說，碘(dian)值(zhi)高得(de)(de)活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)不見(jian)得(de)(de)就(jiu)是好，粉(fen)(fen)狀活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)碘(dian)值(zhi)表征活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)略大(da)于(yu)1.0nm微孔(kong)得(de)(de)發(fa)達程度。由(you)于(yu)碘(dian)分(fen)子大(da)小(xiao)為0.6nm左右。碘(dian)值(zhi)就(jiu)表征活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)大(da)于(yu)0.6nm的(de)(de)有(you)機物的(de)(de)吸(xi)附(fu)(fu)(fu)量(liang)，同時也(ye)表征了大(da)于(yu)該1nm活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)孔(kong)隙(xi)的(de)(de)多(duo)少。粉(fen)(fen)狀活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)碘(dian)值(zhi)的(de)(de)檢測(ce)方法粉(fen)(fen)狀活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)作為一種優良的(de)(de)物理、化學吸(xi)附(fu)(fu)(fu)劑，越來(lai)(lai)(lai)越受到(dao)人們的(de)(de)重視(shi)。隨著(zhu)活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)用途的(de)(de)增加，粉(fen)(fen)狀活(huo)(huo)性(xing)(xing)(xing)(xing)(xing)炭(tan)(tan)(tan)(tan)(tan)的(de)(de)檢測(ce)方法也(ye)越來(lai)(lai)(lai)越多(duo)。但(dan)不同的(de)(de)檢測(ce)方法有(you)可能會發(fa)生(sheng)不同的(de)(de)性(xing)(xing)(xing)(xing)(xing)能指標。

       碘(dian)值一直(zhi)是評估(gu)活(huo)性炭(tan)吸附能力的標(biao)(biao)準。碘(dian)值越(yue)高直(zhi)徑在2.0-8.0mm之(zhi)間，大(da)小誤差在5%之(zhi)間，顆粒越(yue)細(xi)越(yue)小果殼活(huo)性炭(tan)質量越(yue)好。六個(ge)指(zhi)標(biao)(biao)教你區分果殼活(huo)性炭(tan)的好壞催化載體(ti)活(huo)性炭(tan)。

       杏殼活性(xing)炭比表(biao)面積:

       比(bi)表面積是將一克(ke)果(guo)(guo)殼(ke)活性(xing)炭內部空間產開呈現一個面，這(zhe)個平面的面積就是果(guo)(guo)殼(ke)活性(xing)炭的比(bi)表面積，比(bi)表面積大的果(guo)(guo)殼(ke)活性(xing)炭質量就越好。

       機(ji)械(xie)強(qiang)度：機(ji)械(xie)強(qiang)度決定了果殼活性炭的(de)使用(yong)壽命，機(ji)械(xie)強(qiang)度越(yue)高，果殼活性炭強(qiang)度就(jiu)越(yue)高，質量就(jiu)越(yue)好。

       灰(hui)分(fen):灰(hui)分(fen)主要是過客活性炭燒制(zhi)后(hou)殘留物(wu)，灰(hui)分(fen)越低(di)說明果(guo)殼活性炭的(de)燒制(zhi)過程越規(gui)范，殘留物(wu)也就越少。

       決定果殼活性(xing)炭(tan)質(zhi)量(liang)的因素(su)又(you)很多，只有通(tong)過各方面的綜合對比，才能確保果殼活性(xing)炭(tan)的質(zhi)量(liang)。

       粉(fen)狀活性炭的(de)(de)微(wei)孔(kong)(kong)(kong)(kong)可(ke)以(yi)吸(xi)(xi)附(fu)低(di)分(fen)(fen)子(zi)(zi)量的(de)(de)氣(qi)體和溶液中(zhong)的(de)(de)小分(fen)(fen)子(zi)(zi)，但(dan)分(fen)(fen)子(zi)(zi)量較高的(de)(de)分(fen)(fen)子(zi)(zi)不能(neng)進入微(wei)孔(kong)(kong)(kong)(kong)內，中(zhong)孔(kong)(kong)(kong)(kong)提供進入微(wei)孔(kong)(kong)(kong)(kong)的(de)(de)通道，本(ben)身又(you)能(neng)吸(xi)(xi)附(fu)分(fen)(fen)子(zi)(zi)量較高的(de)(de)物質，大孔(kong)(kong)(kong)(kong)則兼有(you)(you)提供通道和吸(xi)(xi)附(fu)的(de)(de)作(zuo)用。如果用活性炭吸(xi)(xi)附(fu)小分(fen)(fen)子(zi)(zi)物質，例如某些(xie)氣(qi)體(毒(du)氣(qi)）和低(di)分(fen)(fen)子(zi)(zi)量的(de)(de)有(you)(you)機物，可(ke)以(yi)使用微(wei)孔(kong)(kong)(kong)(kong)較多的(de)(de)產品(pin)；但(dan)如果要吸(xi)(xi)附(fu)較大的(de)(de)分(fen)(fen)子(zi)(zi)，則要選用有(you)(you)較多中(zhong)孔(kong)(kong)(kong)(kong)的(de)(de)產品(pin)。
