空氣(qi)過(guo)濾棉??過濾布??主要是(shi)過濾空(kong)氣(qi)(qi)中(zhong)(zhong)的(de)塵埃粒子。空(kong)氣(qi)(qi)過濾棉(mian)根據材(cai)質的(de)區(qu)別分為：無紡布，合(he)成纖(xian)維過濾棉(mian)、玻璃纖(xian)維過濾棉(mian)、活性炭過濾棉(mian)、合(he)成纖(xian)維高(gao)(gao)溫(wen)過濾棉(mian)等。空(kong)氣(qi)(qi)過濾棉(mian)按國(guo)標(biao)（GB/T14295）可(ke)分為：初（粗）效，中(zhong)(zhong)效，高(gao)(gao)效，按歐標(biao)可(ke)分為：G1,G2,G3,G4,F5,F6,F7,F8。

初（粗(cu)）效過(guo)(guo)(guo)濾(lv)(lv)(lv)棉(mian)主(zhu)要(yao)過(guo)(guo)(guo)濾(lv)(lv)(lv)大于(yu)(yu)5μm的塵埃(ai)粒子，一般用(yong)(yong)于(yu)(yu)通風設備(bei)和(he)空(kong)氣控制系統吸(xi)入口處作為(wei)預過(guo)(guo)(guo)濾(lv)(lv)(lv)或(huo)粗(cu)過(guo)(guo)(guo)濾(lv)(lv)(lv)等(deng)(deng)直接和(he)室外空(kong)氣接觸的地方(fang)；也多用(yong)(yong)于(yu)(yu)板式過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)，折(zhe)疊板式過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)，袋式過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)等(deng)(deng)過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)材(cai)的濾(lv)(lv)(lv)料。中(zhong)效過(guo)(guo)(guo)濾(lv)(lv)(lv)棉(mian)主(zhu)要(yao)過(guo)(guo)(guo)濾(lv)(lv)(lv)1μm-5μm的塵埃(ai)粒子，一般用(yong)(yong)于(yu)(yu)粗(cu)效過(guo)(guo)(guo)濾(lv)(lv)(lv)之后的二級或(huo)結束(shu)過(guo)(guo)(guo)濾(lv)(lv)(lv)，也多用(yong)(yong)于(yu)(yu)板式過(guo)(guo)(guo)濾(lv)(lv)(lv)器(qi)的濾(lv)(lv)(lv)料。高效用(yong)(yong)于(yu)(yu)小于(yu)(yu)1μm的塵埃(ai)，用(yong)(yong)于(yu)(yu)光(guang)電、lcd液晶制造、生物醫(yi)學、精密儀器(qi)、飲(yin)料食品、pcb印刷等(deng)(deng)行(xing)業無塵凈化車間

典型應(ying)用(yong)：

表面處理和(he)涂裝(zhuang)行業、空氣過濾(lv)與凈化行業是空氣過濾(lv)棉應用很廣泛的行業。
