活性炭對空氣中的苯、甲醛有害物質達到凈化室內空氣的目的

  據浩(hao)合(he)元果殼(ke)活性炭(tan)了解(jie)，空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器采(cai)取的(de)過(guo)(guo)濾(lv)系統(tong)不(bu)同，其(qi)去除的(de)空(kong)(kong)(kong)氣(qi)污染種類也不(bu)同。主要有(you)(you)三種類型，一(yi)(yi)是(shi)(shi)過(guo)(guo)濾(lv)式(shi)空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器，通常是(shi)(shi)以活性炭(tan)作為過(guo)(guo)濾(lv)材料(liao)。通過(guo)(guo)活性炭(tan)過(guo)(guo)濾(lv)掉空(kong)(kong)(kong)氣(qi)中(zhong)的(de)苯、甲醛等(deng)有(you)(you)害物(wu)(wu)質，達到凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)室內(nei)空(kong)(kong)(kong)氣(qi)的(de)目(mu)的(de)。二(er)是(shi)(shi)靜電式(shi)空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器，是(shi)(shi)通過(guo)(guo)吸(xi)(xi)附方式(shi)將空(kong)(kong)(kong)氣(qi)中(zhong)的(de)灰(hui)塵(chen)集(ji)中(zhong)在(zai)集(ji)塵(chen)板(ban)、并(bing)由集(ji)塵(chen)板(ban)上的(de)強電場(chang)殺(sha)死細(xi)菌和(he)病毒(du)，從而達到凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)空(kong)(kong)(kong)氣(qi)的(de)目(mu)的(de)。但(dan)這種空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器對(dui)甲醛、苯等(deng)有(you)(you)害物(wu)(wu)質的(de)吸(xi)(xi)附效果要比過(guo)(guo)濾(lv)式(shi)空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器差一(yi)(yi)些。三是(shi)(shi)光觸(chu)媒式(shi)空(kong)(kong)(kong)氣(qi)凈(jing)(jing)(jing)化(hua)(hua)(hua)(hua)(hua)器，其(qi)對(dui)各(ge)種有(you)(you)害物(wu)(wu)質進(jin)行吸(xi)(xi)附后可以通過(guo)(guo)一(yi)(yi)系列的(de)化(hua)(hua)(hua)(hua)(hua)學(xue)反應將其(qi)轉化(hua)(hua)(hua)(hua)(hua)為無(wu)害的(de)水和(he)二(er)氧化(hua)(hua)(hua)(hua)(hua)碳。但(dan)必(bi)須在(zai)陽光照射或紫外線照射下才(cai)起作用，而且對(dui)于(yu)細(xi)菌的(de)作用也不(bu)太理想。

相(xiang)關(guan)統(tong)(tong)計數(shu)據顯示，近(jin)兩年(nian)(nian)空氣凈化器過(guo)濾(lv)系統(tong)(tong)占比從(cong)(cong)多重(zhong)向二重(zhong)及以下過(guo)濾(lv)系統(tong)(tong)轉變(bian)，尤其(qi)是單純具有(you)活性炭過(guo)濾(lv)系統(tong)(tong)的凈化器越來(lai)越受歡迎。從(cong)(cong)2010年(nian)(nian)至2012年(nian)(nian)前(qian)三季度，活性炭過(guo)濾(lv)系統(tong)(tong)空氣凈化器零售量占比從(cong)(cong)25.1%上升至48.9%。而觸媒(mei)過(guo)濾(lv)系統(tong)(tong)和其(qi)他過(guo)濾(lv)系統(tong)(tong)市場占有(you)率則一路下跌。
