Izinto ezingalukiwe zefayibha ezincibilikisiwe
Indlela yokuncibilika iyindlela ye-polymer eqonde ngqo endleleni ye-net, iwukuncibilika kwe-polymer ngokusebenzisa umoya oshisayo noma ezinye izindlela zokuncibilikisa amaconsi acindezelayo kanye nokwakheka kwe-fiber encane kakhulu, bese iqoqwa ibe yi-roller ye-net noma ikhethini le-net elenziwe kunethiwekhi ye-fiber, ekugcineni yenza umphumela wokunamathela uqiniswe njengoba i-fiber encibilikile ingasebenzi.
Umgomo wokwakha i-fusion-jet fiber
1. Ukufana nomehluko ngendlela ye-spunbonded
Indlela ehlanganisiwe
Eyaziwa nangokuthi indlela yokusonta ngqo ibe yindwangu, ukusetshenziswa kwezindlela zokusonta ezincibilikayo njengesigaba se-polymer ngokuncibilikisa ukwelula kokusonta kanye nokwakheka kwe-filament eqhubekayo yenethiwekhi, bese kuba ngokubopha, ukuqeda kanye neminye imikhiqizo eyenziwe ngezinqubo.
Okuvamile
I-polymer kumele ikhishwe yimbobo ye-spinneret esimweni esincibilikisiwe
(2) inethiwekhi yefayibha ingaba ukubopha okushisayo (ukubopha okungaphezulu noma ukubopha okuqondile) noma ukubopha kwayo kube ukuqinisa indwangu okungeyona eyolukiwe
umehluko B
Ngendlela ye-spunbond: umoya obandayo ngokuzumayo uyaphola, ngesikhathi esifanayo, welula, wakha intambo eqhubekayo, usakazeka ekhethinini elinetha
Indlela yokufutha encibilikisayo: ukufutha komoya oshisayo ngesivinini esikhulu, ngokwelula kakhulu, ukwakheka kwefayibha emfushane kakhulu, ngesivinini esikhulu kakhulu ukundiza ungene ekhethinini lenethi noma i-roller enethi ejiyile ukuze kwakheke inethiwekhi yefayibha
(2) indlela ye-spunbond: izindlela zokuqinisa inethiwekhi ye-fiber, ngaphezu kokubopha okushisayo, kodwa futhi thatha i-acupuncture, amanzi, ukubopha kwamakhemikhali nezinye izindlela
Indlela yokufafaza encibilikisayo: ikakhulukazi incike ekubopheni ukushisa noma ekubopheni ngokwakho
2. Inqubo yezobuchwepheshe yendabuko
Ukondla nge-polymer → ukuncibilikisa i-extrusion → ukwakheka kwefayibha → ukupholisa ifayibha → ukwakha i-mesh → ukubopha (i-mesh ehleliwe) → ukugoqa okunqenqemeni → ukuqedwa kwangemva kokuqeda noma okukhethekile
Ukudla kwe-polymer - i-polymer ngokuvamile yenziwa ibe yizicucu ezincane eziyindilinga, ezi-granular, ezithelwa ebhakedeni noma ehopheni, bese zifakwa ku-screw extruder
Ukwehliswa kwe-Melt -- ekugcineni kokudla kwe-screw extruder, isilayi se-polymer kufanele sixutshwe ne-stabilizer, i-agent yokwenza mhlophe nezinye izithasiselo, i-color masterbatch nezinye izinto zokusetshenziswa ezidingekayo, ngemva kokuxuba ngokuphelele kwi-screw extruder, kufudunyezwe kube yi-melt, bese ekugcineni ukuncibilika kuzofakwa kwi-spinneret ngepompo yokulinganisa ngesihlungi. Enkambisweni yokuncibilika nokufutha, i-extruder ejwayelekile nayo inciphisa isisindo sama-molecule se-polymer ngesenzo sayo sokucheba kanye nokuwohloka kokushisa.
Ukwakheka kwefayibha - ukuncibilika okuhlanzekile okuhlungiwe kudlula ohlelweni lokusabalalisa futhi kuphakelwa ngokulinganayo kusethi ngayinye yama-spinneret ukuze kukhiqizwe inani elifanayo lokukhipha i-spinneret ngayinye. I-spinneret yefayibha efuthwe nge-fusion ihlukile kwezinye izindlela zokuphotha, imigodi ye-spinneret kumele ihlelwe ngendlela eqondile, izinhlangothi eziphezulu nezingezansi zazo ezinemigodi ye-jet.
Ukupholisa ifayibha - inani elikhulu lomoya wokushisa kwegumbi lidonswa ezinhlangothini zombili ze-spinneret bese lixutshwa nomoya oshisayo oqukethe i-microfiber ukuze uphole. I-microfiber encibilikisiwe iyaphola futhi iqine.
Ukuhlanganisa inethi - ekukhiqizweni kwe-nonwovens ye-fiber eqhutshwe yi-fusion, ama-spinneret angabekwa ngokuvundlile noma ngokuvundlile. Uma ebekwe ngokuvundlile, i-microfiber ifuthwa esigubhuni sokuqoqa esiyindilinga ukuze kwakheke inethi. Uma ebekwe ngokuvundlile, imicu iwela esikrinini esihamba ngokuvundlile ukuze kwakheke inethi.
I-Adhesive (inethiwekhi ehleliwe) - ukuqinisa okunamathiselwe ngenhla okukhulunywe ngakho ngenhla, ngezinye izinjongo zendwangu yokufafaza encibilikayo kwanele, njengokuthi: izidingo zenethiwekhi yefayibha zinesakhiwo esithambile, ukugcinwa komoya okuhle noma isilinganiso se-void. Futhi kwezinye izinto eziningi, ukuzihlanganisa ngokwakho akwanele, kusadinga i-hot rolling agglutination, i-ultrasonic agglutination noma ezinye izindlela zokuhlanganisa. I-Hot glue
3. Izici zenqubo ye-melt-jet fiber nonwovens
(1) inqubo emfushane, ukusebenza kahle kokukhiqiza okuphezulu;
I-fiber incane kakhulu, ukufana kwe-fiber mesh kuhle, kuthambile, kuyahlunga, kuyabulala amagciwane, ukumuncwa kunezinzuzo ezinhle kakhulu;
Ukuma kwefayibha kuphansi, amandla enethiwekhi yefayibha aphansi;
Lokhu kuzodla amandla amaningi.
Imigomo eyinhloko yenqubo yokukhiqiza yendlela yokufafaza encibilikisiwe
1. Inkomba yokuncibilika (i-MFI)
Amandla kanye nobude lapho indwangu efuthwe nge-fusion yehla ngokwanda kwe-MFI. Ngakho-ke, i-MFI yezinto zokusetshenziswa iyadingeka ukuthi ibe phezulu ngangokunokwenzeka ukuze ukugeleza kokuncibilika okuncane kuthole uhlaka olungcono enqubweni ye-hot gas jet.
2. Isivinini sokugeleza kwegesi esishisayo
Ngaphansi kokushisa okufanayo, isivinini sesikulufu, ibanga lokwamukela kanye nezinye izimo:
Isivinini somoya oshisayo ↑ → ububanzi befayibha ↓ → Ukuzwa okungalukiwe kusuka kokunzima kuya kokuthambile, ukugoba kwefayibha kuyanda, inethiwekhi yefayibha iminyene, ibushelelezi, amandla akhuphukile
Kodwa ijubane lomoya likhulu kakhulu, kulula ukulibona njengezimbali ezindizayo, kuthinta kakhulu ukubukeka kwendwangu
3. I-engela yokujova umoya oshisayo
Kuthinta kakhulu umphumela wokuthamba kanye nesimo sefayibha
Izici kanye nokusetshenziswa kwe-melt-jet fiber (indwangu engalukiwe)
1. Izinto zokuhlunga
ISEBENZISA kakhulu isakhiwo sayo sefayibha esithambile kakhulu, okuyinkambu yayo yokuqala nenkulu kunazo zonke yokusetshenziswa. Isidingo sezinto ezintsha zokuhlunga futhi yisona sizathu esiyinhloko sokuthuthukiswa kwe-nonwovens yefayibha encibilikisiwe.
Akukho uboya obufushane bezinto zokuhlunga eziwela kugesi noma uketshezi oluhlanziwe ngemva kokuhlunga ngendwangu yokufafaza encibilikisiwe.
Njengamanje, kusetshenziswa amathani angaphezu kuka-20,000 ezinto zokuhlunga ze-melt-jet emhlabeni minyaka yonke, angu-65% awo asetshenziselwa ukuhlunga uketshezi, njengokuthi: ukuhlunga iziphuzo kanye nokuhlanzwa kokudla, ukuhlunga amanzi, ukuhlunga insimbi eyigugu, upende kanye nopende kanye neminye imikhiqizo yamakhemikhali; u-35% usetshenziselwa ukuhlunga igesi, njengokuthi: ukuhlunga umoya opholile wangaphakathi, ukuhlunga kokuhlukanisa umoya namanzi, ukuhlunga igumbi lokuhlanza.
2. Izinto zokwelapha
Njengamanje, iyinkambu yesibili ngobukhulu yokusebenzisa indwangu yokufutha encibilikayo.
Kule ndawo, umthamo omkhulu kakhulu yi-dressing yokuhlinzwa, amakhethini egumbi lokuhlinza kanye nendwangu yokuhlanza amagciwane, kanye nenani elincane le-bandage enwebekayo, i-tape, nefilimu yokunciphisa ukuvuvukala.
3. Izinto zokuhlanzeka
(1) kuma-napkin ahlanzekile
★ indwangu yokufafaza encibilikisiwe efakwe engxenyeni engaphakathi yokumunca ye-napkin ehlanzekile, ungqimba lokudlulisa ama-capillary
★ ukusetshenziswa kwendwangu yokufutha encibilikayo njengesivikelo engqimbeni yokuvimbela ukungena koketshezi, enezendlalelo ezimbili zendwangu yokufutha encibilikayo esikhundleni sefilimu engangenisi i-polyethylene
(2) maqondana namanabukeni abantu abadala
Enqubweni yokukhiqiza, imicu emifushane ye-pulp yokhuni ixutshwa ekugelezeni kwemicu ye-fusiform ukuze kwakhiwe indwangu ekhethekile ye-fusiform emunca kahle.
4. Izinto ezimunca uwoyela
Njengezinto ezimunca amafutha, amandla okumunca amafutha angafinyelela isisindo esiphindwe kayi-17 kunesisindo sawo.
Ngokuvamile, indwangu yokufutha efuthayo ifakwa epayipini elide elinemeshi elithungwe ngentambo ye-PET njengegridi yamanzi entantayo yokumelana namafutha nokumuncwa kwamafutha olwandle. Ingafakwa futhi ekhanda lokudonsa olwandle okwenziwe ngedivayisi yokuqoqa uwoyela wendwangu yokufutha encibilikisa i-PP, ukuhlanza uwoyela okuqhubekayo ebusweni.
5. Izinto zokugqoka
(1) izinto ezifudumele
Ukusetshenziswa okuphumelele kakhulu yindwangu ekhethekile efuthwe nge-fusion eyenziwe yinkampani ye-3M e-United States: enkambisweni ye-fusion-sprayed fiber, i-PET staple fiber ixutshwa ukuze kwakhiwe isakhiwo sokuvikela umoya esakhiwe yi-PET staple fiber enokuqina okuhle kanye ne-PP ultrafine fiber.
(2) izingubo zomsebenzi ezilahlwayo
Ukusetshenziswa okuyinhloko kwendwangu ehlanganisiwe ye-SMS, ngaphezu kwengubo yokusebenza, kusetshenziswe ngempumelelo ekusetshenzisweni kwezingubo zokuzivikela ezimbonini.
6, indwangu ehlanzekile
Ngokuyinhloko ukusetshenziswa kwe-PP ukumuncwa kwamafutha emvelo, okuhlukahlukene okusetshenziselwa ukungcola kwamafutha endaweni yokusebenza.
Ngokuthuthuka kobuchwepheshe bokucubungula ukuncibilikisa nokufutha, indwangu yokuncibilikisa nokufutha ye-PP enesakhiwo esithinta amanzi ingenziwa ngesengezo esifanele sokufaka umswakama, esingasetshenziswa ezibhedlela, emakamelweni okuhlanza kakhulu, ezingxenyeni ezinembile, ezinsimbini nasemakamelweni ekhompyutha.
