indlela yokwenza ilaphu elinyibilikisiweyo
1. Ifayibha kufuneka ilunge, izinga lokunyibilika kwezinto eziluhlaza kunye nobubanzi bepleyiti yespinneret ziyahambelana, kwaye inkqubo yespinneret iyalungiswa, ukuze ifayibha ifikelele kwi-0.3um.
2. Ukudibanisa izixhobo ze-electret ezilungileyo nokukhetha i-electret masterbatch elungileyo. I-electret master particle elungileyo kufuneka ibe nakho ukugcina itshaja kwaye ivelise intsimi yombane ngokusisigxina.
3. Ixesha lokusebenza kwemaski kwi-electret lixhomekeke kakhulu kumxholo we-electret masterbatch. I-Electret masterbatch ifana nebhetri, ukongeza umlinganiselo kuya kumisela ubomi bayo kunye nomthamo wokufunxa.
4. Yomisa ilaphu elinyibilikisiweyo uze uligcine. Alinakudibana nokufuma komoya wangaphandle. Ukupakisha i-vacuum yeyona nto ilungileyo. Ukufuma emoyeni kunye netshaja kwilaphu elinyibilikisiweyo kuya kuguqulwa kube yi-ions ezingezizo, kwaye ukulahleka kwetshaja kuya kuchaphazela ukusebenza kakuhle kokuhluza.
3. Izizathu zelaphu elinyibilikisiweyo elingaphantsi komgangatho
1. Izixhobo zeSpinneret kunye nezixhobo ezinyibilikisiweyo
2.izixhobo ze-electrostatic electret
3.Izixhobo ze-electrostatic electret master zexesha elide
4.izinto zokutshiza ezinyibilikayo okanye izinto zefayibha yomnwe ezinyibilikayo kakhulu
5.ingcali kunye namava okulungisa umatshini
6. Ulawulo lwesiza semveliso enyibilikisiweyo
indlela yokukhetha izinto ezinyibilikisiweyo
1.ukunyibilika: i-polypropylene ngokongeza i-peroxides thermal degradation okanye indlela yokulungisa i-hydrogen ye-metallocene, ukunyibilika kwe-polypropylene ukufikelela kwinqanaba eliphezulu elifanelekileyo, kunokuvelisa i-nanoscale fiber.
2. Iqondo lokunyibilika kwamasuntswana kufuneka lincitshiswe libe phakathi kwe-150-170°C.
3. Emva kokongeza i-electret master particle, ilaphu elinyibilikayo liya kuvelisa ukusebenza kwe-electrostatic adsorption ngesixhobo se-electret ukuthintela intsholongwane.
4.Emva kokuguqulwa kwamasuntswana e-polypropylene, ifayibha ekhutshwa ngumatshini welaphu elinyibilikisiweyo kubushushu obuphezulu kunye noxinzelelo oluphezulu ilungile kwaye inde.
5. Ifayibha yolwelo ekhutshwa kwi-nozzle yokuzinyibilikisa kwezinto eluhlaza ithambile, iqinile kwaye iqinile.
6.ukubulala iintsholongwane kubushushu obuphezulu.
ukhetho lwebhetshi ye-electret master
1. ixesha lomthwalo we-electrostatic, nokuba ingatshajwa ixesha elide ukuya kuthi ga kunyaka omnye nangaphezulu.
2. i-electret masterbatch ayiwuvali umngxuma we-meltblown, itshaja yomthwalo welaphu le-meltblown, ingenza njani ukuba itshaja entle ihlale ixesha elide kwilaphu le-meltblown, ingenza njani
Emva kweenyanga ezintandathu okanye emva konyaka kungekho lahleko yentlawulo, yiba yi-test electret master batch kunye ne-electret process key index.
3. Umjikelo webhloko ende, i-electret enesiphumo esinde, i-PFE idlula i-95.
Unyango lwenkqubo ye-Electret
1. Eyona ndlela isetyenziswa kakhulu yindlela yokutshaja i-corona xa kunyangwa ilaphu elinyibilikisiweyo ngombane. I-voltage yokutshaja, ixesha lokutshaja, umgama wokutshaja kunye nokufuma kokusingqongileyo konke oku kunefuthe kwisiphumo sonyango lokutshaja ngombane.
I-voltage yokutshaja inefuthe elicacileyo kwisiphumo se-electret, umgama wokutshaja unefuthe eliphakathi, kwaye ixesha lokutshaja linefuthe elincinci. Nika ingqalelo xa ulungisa umatshini.
2. Ukufuma okungqongileyo kunempembelelo ekuvelisweni nasekulahlekeni kombane ongashukumiyo. Ishishini lelaphu eliqhushumbisiweyo kufuneka lijonge ubushushu kunye nokufuma kwindawo yokusebenzela ngamaxesha onke. Yandisa izixhobo ezifanelekileyo ukugcina ubushushu kunye nokufuma kwindawo yokusebenzela kuluhlu oluthile.
izinto ezinyibilikisiweyo
1. Ukuba i-meltblown polypropylene ihlala kubushushu obuphezulu kunye noxinzelelo ixesha elide, kulula ukuyitshisa kwaye iyenze ibe yi-carbonize.
2. Xa ulungisa ubushushu bomatshini, okokuqala, kuyimfuneko ukumisela ukuba ubushushu bokwenyani bomgqomo kunye nesikhunta kumatshini oqhushumbisiweyo buhambelana nobushushu obumiselweyo. Ngokwesiqhelo ubushushu obuncinci bokubonisa izixhobo eziqhushumbisiweyo kunye nobushushu bokwenyani buya kwahluka kakhulu.
3. Ukunyibilika kubhekisa kwi-polypropylene eyi-1500, ukuba ubushushu bubekwe ngaphezulu kwama-270℃, buphezulu kancinci.
Ukukhetha izixhobo zokuvuthela ezinyibilikayo
1. Uqwalaselo kufuneka lugqitywe: i-extruder → i-screen changer (filter)→ i-metering pump → i-die head → i-distribution plate (umoya oshushu oncedisayo)→ i-spinneret → isixhobo se-mesh sokwenza ilaphu elinyibilikisiweyo.
2. isantya sokukhupha amanzi, iiparameter zepompo yokulinganisa, iingenelo kunye neziphene zentloko yedayi, iiparameter zobushushu kunye nesantya sokuhamba komoya oshushu, i-Angle yentloko yedayi, i-Angle yeblade yomoya, umgama wokufumana izinto ezinyibilikisiweyo, iiparameter zokufunxa phantsi kwesixhobo sokwenza inethi njalo njalo zimisela umgangatho welaphu lokutshiza elinyibilikisiweyo.
Oku kungentla yinkqubo yokuvelisa ilaphu elingalukwanga elinyibilikisiweyo. Singumvelisi welaphu elingalukwanga ochwepheshileyo, iHuizhou Jinhaocheng Non-woven Co., Ltd. Ndiyathemba ukuba eli nqaku libe luncedo kuwe.
