鄭州電鍍用粉末活性炭作用
如何識別粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)吸(xi)附值的(de)(de)(de)(de)(de)高低?1、直接看廠家提供的(de)(de)(de)(de)(de)指標;2、看體積(ji):要(yao)想(xiang)提高粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)的(de)(de)(de)(de)(de)吸(xi)附性(xing)(xing)能,只有盡可能多地在(zai)粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)上(shang)制造(zao)孔(kong)(kong)隙(xi)結構,孔(kong)(kong)隙(xi)越(yue)多,粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)越(yue)酥松,相對密度也就越(yue)輕,因此好(hao)(hao)的(de)(de)(de)(de)(de)粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)手感上(shang)會(hui)比(bi)較輕,在(zai)同(tong)等(deng)重量包裝的(de)(de)(de)(de)(de)情況下,性(xing)(xing)能好(hao)(hao)的(de)(de)(de)(de)(de)粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)會(hui)比(bi)劣質活(huo)性(xing)(xing)炭(tan)(tan)體積(ji)大許多。3、看氣(qi)泡(pao):將一小(xiao)(xiao)把活(huo)性(xing)(xing)炭(tan)(tan)投入水中(zhong),由于水的(de)(de)(de)(de)(de)滲(shen)透作(zuo)用(yong),水會(hui)逐漸浸入粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)的(de)(de)(de)(de)(de)孔(kong)(kong)隙(xi)結構中(zhong),迫使孔(kong)(kong)隙(xi)中(zhong)的(de)(de)(de)(de)(de)空(kong)氣(qi)排出,從(cong)而產生(sheng)一連串的(de)(de)(de)(de)(de)極(ji)為細小(xiao)(xiao)的(de)(de)(de)(de)(de)氣(qi)泡(pao),在(zai)水中(zhong)拉出一條細小(xiao)(xiao)的(de)(de)(de)(de)(de)氣(qi)泡(pao)線(xian),同(tong)時會(hui)發出絲絲的(de)(de)(de)(de)(de)氣(qi)泡(pao)聲,十分(fen)有趣。這種現象發生(sheng)得越(yue)劇烈,持續時間(jian)越(yue)長,粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)的(de)(de)(de)(de)(de)吸(xi)附性(xing)(xing)就越(yue)好(hao)(hao)。粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)普遍應用(yong)于食品、飲料、醫(yi)藥(yao)、自來水、糖、油(you)脂(zhi)等(deng)行業。鄭州電鍍(du)用(yong)粉(fen)末(mo)活(huo)性(xing)(xing)炭(tan)(tan)作(zuo)用(yong)
粉(fen)(fen)末活性炭(tan)以(yi)桃殼、杏殼等(deng)果(guo)核殼為(wei)原(yuan)(yuan)料(liao)(liao),經系列生產(chan)工(gong)藝精加工(gong)而成。外(wai)觀為(wei)黑色(se),呈顆粒狀,具有空隙(xi)發達、吸附性能好、經濟耐用(yong)(yong)(yong)等(deng)優點(dian)。產(chan)品主(zhu)要用(yong)(yong)(yong)于電(dian)廠鍋爐用(yong)(yong)(yong)水(shui),工(gong)業用(yong)(yong)(yong)水(shui),生活用(yong)(yong)(yong)水(shui),飲料(liao)(liao)用(yong)(yong)(yong)水(shui)及其(qi)他各種(zhong)工(gong)業廢(fei)水(shui)的(de)(de)凈(jing)化、提純、脫色(se)等(deng)。制(zhi)備粉(fen)(fen)末活性炭(tan)的(de)(de)原(yuan)(yuan)料(liao)(liao)十分(fen)(fen)普遍,含碳物(wu)質(zhi)(zhi)均可(ke)以(yi)成為(wei)制(zhi)備粉(fen)(fen)末活性炭(tan)的(de)(de)原(yuan)(yuan)料(liao)(liao),這些原(yuan)(yuan)料(liao)(liao)同樣(yang)也(ye)可(ke)適用(yong)(yong)(yong)于粉(fen)(fen)末活性炭(tan)的(de)(de)制(zhi)備,它們主(zhu)要分(fen)(fen)為(wei)兩(liang)大(da)類:煤(mei)質(zhi)(zhi)原(yuan)(yuan)料(liao)(liao)、木質(zhi)(zhi)原(yuan)(yuan)料(liao)(liao)。煤(mei)質(zhi)(zhi)原(yuan)(yuan)料(liao)(liao)主(zhu)要有無煙煤(mei)、煤(mei)泥、褐剁及石(shi)油焦及煤(mei)基類;木質(zhi)(zhi)原(yuan)(yuan)料(liao)(liao)主(zhu)要指核桃殼、木材、果(guo)殼、竹(zhu)質(zhi)(zhi)、農(nong)作物(wu)秸稈(gan)、含碳廢(fei)渣等(deng)。此外(wai),利用(yong)(yong)(yong)除(chu)塵灰(hui)分(fen)(fen)離炭(tan)粉(fen)(fen)和廢(fei)聚苯乙(yi)烯泡沫等(deng)原(yuan)(yuan)料(liao)(liao)也(ye)可(ke)以(yi)制(zhi)備出質(zhi)(zhi)量較(jiao)好的(de)(de)粉(fen)(fen)末活性炭(tan)。鄭州電(dian)鍍用(yong)(yong)(yong)粉(fen)(fen)末活性炭(tan)作用(yong)(yong)(yong)粉(fen)(fen)末活性炭(tan)對去(qu)除(chu)水(shui)中的(de)(de)色(se)、嗅、味(wei)及有機物(wu)具有較(jiao)好的(de)(de)效(xiao)果(guo)。
糖脫(tuo)色是粉(fen)(fen)末(mo)活性(xing)(xing)炭較古(gu)老的(de)(de)應用(yong)之一。糖液(ye)中(zhong)含有多(duo)種有色物質,如類(lei)黑精(jing)、焦糖和(he)鐵(tie)多(duo)酚絡合(he)物等(deng),其(qi)中(zhong)類(lei)黑精(jing)對糖晶(jing)體的(de)(de)色值影響(xiang)大。十(shi)八世紀前(qian)后,人們(men)已經使(shi)(shi)用(yong)骨炭和(he)木炭進(jin)行糖脫(tuo)色。從二十(shi)世紀開始,粉(fen)(fen)末(mo)活性(xing)(xing)炭逐漸取代骨炭。粉(fen)(fen)末(mo)活性(xing)(xing)炭孔隙(xi)結構(gou)發達且大孔、中(zhong)孔、微孔并存,使(shi)(shi)其(qi)對各種有色物質均可(ke)有效(xiao)脫(tuo)除,對類(lei)黑精(jing)的(de)(de)脫(tuo)附效(xiao)果尤其(qi)出色,因而(er)被普(pu)遍應用(yong)。粉(fen)(fen)狀粉(fen)(fen)末(mo)活性(xing)(xing)炭除了脫(tuo)色作用(yong)以外,還能夠脫(tuo)除糖液(ye)中(zhong)的(de)(de)膠質和(he)表面活性(xing)(xing)雜質,使(shi)(shi)糖液(ye)增加表面張力,減(jian)少蒸發時(shi)產生(sheng)的(de)(de)泡沫,提高潔凈速度(du),進(jin)而(er)改善(shan)食糖結晶(jing)與(yu)糖蜜的(de)(de)分離效(xiao)果。
粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)在(zai)(zai)我(wo)們的(de)(de)(de)(de)(de)日常生(sheng)活(huo)(huo)(huo)中應用非常普(pu)遍(bian),一(yi)(yi)般我(wo)們在(zai)(zai)新房裝修(xiu)后(hou)或(huo)買來的(de)(de)(de)(de)(de)木(mu)質衣柜中都會放(fang)一(yi)(yi)定的(de)(de)(de)(de)(de)粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)來去除屋(wu)內異味,以及甲醛等(deng)有(you)害氣(qi)體。粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan),是(shi)(shi)一(yi)(yi)種(zhong)吸(xi)附力(li)非常強的(de)(de)(de)(de)(de)無定型炭(tan)(tan)。粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)是(shi)(shi)一(yi)(yi)種(zhong)經(jing)過特(te)殊(shu)處(chu)理的(de)(de)(de)(de)(de)炭(tan)(tan)。粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)具有(you)一(yi)(yi)種(zhong)明顯的(de)(de)(de)(de)(de)“物理吸(xi)咐(fu)”和(he)(he)“分析(xi)化學(xue)吸(xi)咐(fu)”的(de)(de)(de)(de)(de)作用,可將一(yi)(yi)些分析(xi)化學(xue)化合物吸(xi)咐(fu)而(er)達到去除效果的(de)(de)(de)(de)(de)作用。粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)主要是(shi)(shi)指將有(you)機原料在(zai)(zai)與(yu)外界空氣(qi)隔(ge)離的(de)(de)(de)(de)(de)條件下進行加熱,并與(yu)氣(qi)體發(fa)生(sheng)反應,導致其(qi)表(biao)面(mian)(mian)生(sheng)成孔(kong)(kong)狀結(jie)構(gou)。也就(jiu)是(shi)(shi)發(fa)生(sheng)炭(tan)(tan)化與(yu)活(huo)(huo)(huo)化的(de)(de)(de)(de)(de)過程。經(jing)過活(huo)(huo)(huo)化的(de)(de)(de)(de)(de)粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)表(biao)面(mian)(mian)產生(sheng)了無數的(de)(de)(de)(de)(de)細(xi)小(xiao)孔(kong)(kong)隙。而(er)這些微孔(kong)(kong)直(zhi)徑大多在(zai)(zai)2~50nm之間,于是(shi)(shi)就(jiu)形成了巨(ju)大的(de)(de)(de)(de)(de)微孔(kong)(kong)表(biao)面(mian)(mian)。由于其(qi)這種(zhong)獨特(te)的(de)(de)(de)(de)(de)結(jie)構(gou)特(te)性(xing)(xing)(xing)(xing),因此被普(pu)遍(bian)應用生(sheng)產和(he)(he)生(sheng)活(huo)(huo)(huo)中。粉(fen)(fen)末活(huo)(huo)(huo)性(xing)(xing)(xing)(xing)炭(tan)(tan)在(zai)(zai)垃(la)圾焚燒發(fa)電(dian)和(he)(he)固(gu)廢垃(la)圾焚燒處(chu)理領域(yu)普(pu)遍(bian)使用。
