微孔(kong)折(zhe)疊濾(lv)(lv)(lv)芯(xin)是一(yi)種廣泛(fan)應用于水處(chu)理、氣體分離等領域的(de)(de)(de)過濾(lv)(lv)(lv)元件。其生產工藝流(liu)程主要(yao)包括以下步(bu)驟：1.原材(cai)料(liao)準備，包括聚（PP）或(huo)尼龍（PA）、無紡布以及保(bao)護性涂層(ceng)材(cai)料(liao)；2.將原料(liao)熔融擠出成(cheng)中空纖維膜片材(cai)；3.用機(ji)械拉伸法將薄膜進一(yi)步(bu)拉制(zhi)成(cheng)高精度薄壁管(guan)狀結構(gou)；4.在多通(tong)道(dao)模具(ju)的(de)(de)(de)折(zhe)彎槽內對上述細(xi)長的(de)(de)(de)超高壓平直單絲(si)進行壓褶(zhe)成(cheng)型并加熱固(gu)化形成(cheng)密閉空間作為(wei)液體流(liu)動的(de)(de)(de)空間;高通(tong)透性的(de)(de)(de)紙(zhi)質(zhi)墊片的(de)(de)(de)包裹固(gu)定好確保(bao)與被過濾(lv)(lv)(lv)的(de)(de)(de)介質(zhi)完全接觸從而構(gou)成(cheng)一(yi)個(ge)獨立(li)完整的(de)(de)(de)過濾(lv)(lv)(lv)單元體。

微孔(kong)折疊濾芯(xin)的(de)(de)工(gong)作原理主(zhu)要(yao)受(shou)兩個因素影(ying)響：1.過(guo)濾精度。隨著溫度的(de)(de)升(sheng)高，直徑較(jiao)小的(de)(de)顆粒在(zai)(zai)水中(zhong)(zhong)分散懸浮(fu)性(xing)提高，微孔(kong)折疊濾芯(xin)訂做(zuo)，更(geng)容(rong)易滲(shen)透進濾材中(zhong)(zhong)吸(xi)附、結合和沉積下(xia)來(lai)形(xing)成(cheng)沉淀物；而一(yi)些大(da)(da)粒徑固體雜質則容(rong)易卡死或堵塞住進水口小孔(kong)。當液(ye)體流過(guo)這(zhe)些由被截留物質組成(cheng)的(de)(de)網狀通道時（即(ji)納米(mi)級溝槽），液(ye)體的(de)(de)壓(ya)力(li)能轉化為(wei)動(dong)能與粘滯阻力(li)克服膜(mo)壁阻力(li)和凹凸不平處(chu)產生(sheng)的(de)(de)切應力(li)，大(da)(da)慶(qing)微孔(kong)折疊濾芯(xin)，實現(xian)固-液(ye)分離。因此(ci)，微孔(kong)折疊濾芯(xin)定做(zuo)，如果選擇不當可(ke)能會對不同黏度的(de)(de)物料產生(sheng)堵嘴(zui)現(xian)象使泵吸(xi)不上(shang)來(lai)料導致無(wu)法正常工(gong)作。2.材料本身性(xing)能的(de)(de)影(ying)響主(zhu)要(yao)體現(xian)在(zai)(zai)以下(xia)幾(ji)個方面：（i）親水性(xing)好/憎水性(xing)強—易洗脫；（ii）壓(ya)差增(zeng)大(da)(da)快(kuai)—更(geng)換周期短；（iii）出水電導率(lv)上(shang)升(sheng)明(ming)顯—不穩定。（iv)出水量下(xia)降很快(kuai)，（v）反沖(chong)徹凈度低；(vi)使用(yong)壽命大(da)(da)大(da)(da)縮短。

水(shui)處理微孔折疊濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)在使(shi)(shi)用(yong)(yong)(yong)(yong)過程中需(xu)要(yao)注意以下(xia)(xia)問題：1.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的清(qing)潔(jie)(jie)(jie)：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)需(xu)要(yao)定期清(qing)潔(jie)(jie)(jie)，以保證(zheng)其(qi)過濾(lv)(lv)(lv)(lv)(lv)效(xiao)(xiao)果(guo)(guo)。清(qing)潔(jie)(jie)(jie)時(shi)(shi)應(ying)使(shi)(shi)用(yong)(yong)(yong)(yong)清(qing)水(shui)或者適(shi)當(dang)的清(qing)潔(jie)(jie)(jie)劑，微孔折疊濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)廠(chang)，避免(mian)使(shi)(shi)用(yong)(yong)(yong)(yong)硬物刮(gua)擦濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)。2.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的更換(huan)：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)有限，需(xu)要(yao)定期更換(huan)。更換(huan)濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)時(shi)(shi)應(ying)確保新(xin)濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的尺寸和(he)類型與舊濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)相同，以保證(zheng)過濾(lv)(lv)(lv)(lv)(lv)效(xiao)(xiao)果(guo)(guo)。3.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的儲(chu)存：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)在不使(shi)(shi)用(yong)(yong)(yong)(yong)時(shi)(shi)應(ying)儲(chu)存在干燥、清(qing)潔(jie)(jie)(jie)的環(huan)境(jing)中，避免(mian)陽光直射(she)和(he)潮濕。4.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的安裝：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的安裝應(ying)正確，避免(mian)安裝不緊密導致過濾(lv)(lv)(lv)(lv)(lv)效(xiao)(xiao)果(guo)(guo)下(xia)(xia)降或者濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)。5.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的質(zhi)量(liang)：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的質(zhi)量(liang)直接影響其(qi)過濾(lv)(lv)(lv)(lv)(lv)效(xiao)(xiao)果(guo)(guo)和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)，應(ying)選(xuan)擇(ze)質(zhi)量(liang)可靠的濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)。6.濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的使(shi)(shi)用(yong)(yong)(yong)(yong)環(huan)境(jing)：濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)的使(shi)(shi)用(yong)(yong)(yong)(yong)環(huan)境(jing)也(ye)會影響其(qi)過濾(lv)(lv)(lv)(lv)(lv)效(xiao)(xiao)果(guo)(guo)和(he)使(shi)(shi)用(yong)(yong)(yong)(yong)壽(shou)命(ming)，應(ying)根據實際(ji)使(shi)(shi)用(yong)(yong)(yong)(yong)環(huan)境(jing)選(xuan)擇(ze)合適(shi)的濾(lv)(lv)(lv)(lv)(lv)芯(xin)(xin)(xin)(xin)。
