Izakhiwo ze-Melt blown Nonwovens | JINHAOCHENG

Yiziphi izici zeizinto ezingezona ezelukiwe eziqhunyisiweNamuhla, ake sibheke okulandelayo. Ngithemba ukuthi kuzokusiza.

Izici zokusebenza kwe-Melt blown Nonwovens

Izinto ezingalukiwe ezincibilikisiwe luhlobo oluthileizinto ezingezona ezelukiwengesakhiwo sefayibha esicolekile kakhulu, esilungiswa ngenqubo yokuncibilika kanye nokudweba komoya oshisayo ocindezelwe kakhulu. Ama-nonwovens ancibilikisiwe asephenduke into yokuhlunga ebaluleke kakhulu ngenxa yokusebenza kwayo okuhle kakhulu kokuhlunga, isivuno esikhulu kanye nobuchwepheshe bokucubungula obulula. Izinto zokuhlunga ezilungiselelwe ngendlela yokuncibilika zinenzuzo yokuqina kwefayibha okulungisekayo, isakhiwo esingcolile nesithambile esinezinhlangothi ezintathu kanye nokusebenza kahle kokuhlunga okuphezulu. Idlala indima ebalulekile kwezokwelapha nasempilweni, embonini yamakhemikhali okudla, kuma-microelectronics, ekuvikelweni kwemvelo nakweminye imikhakha.

Ngaphansi kwesisekelo sokuthi ezinye izimiso zenqubo azishintshi, ingcindezi yomoya oshisayo inethonya elikhulu ezimpahleni ze-nonwovens. Ngokwanda kwengcindezi yomoya oshisayo, ukungena komoya komkhiqizo kwehla kancane kancane, okungukuthi, ukungena komoya kuyancipha. Ngemva kokuba i-fiber ikhishwe emgodini we-spinneret, iyanwebeka futhi icwengisiswe ngaphansi kokudonsa komoya oshisayo. Ingcindezi yomoya oshisayo ephezulu izuzisa kakhulu ekucwengisisweni kwe-fiber. Ngakho-ke, ngokwanda kwengcindezi yomoya oshisayo, ububanzi be-fiber buba buncane. Lapho imicu eminingi igcwele futhi inqwabelana ngokungajwayelekile emishinini ye-mesh ukuze kwakheke ama-nonwoven ancibilikisiwe, lapho imicu inciphile, kulula ukwakha ama-nonwovens ane-porosity ephezulu nendawo ephezulu yobuso, futhi ububanzi be-pore obakhiwe phakathi kwemicu buncane kakhulu. Ngakho-ke, ukusebenza kahle kokubanjwa kwezinhlayiya nakho kuphakeme.

Ngaphansi kwesisekelo sokuthi ezinye izilinganiso zenqubo azishintshi, umfutho womoya oshisayo unethonya elikhulu ezimpahleni zezingubo ezingezona ezelukiwe. Njengoba izinga lokushisa lomoya oshisayo likhuphuka kancane kancane.

Ukuvuleka komoya komkhiqizo kwehla kancane kancane, okungukuthi, ukuvuleka komoya kwehla. Ngemva kokuba i-fiber ikhishwe emgodini we-spinneret, iyaqhubeka icwengisiswa ngaphansi kokudonsa komoya oshisayo. Izinga lokushisa lomoya oshisayo eliphakeme linganikeza ukushisa okwengeziwe, okunciphisa inqubo yokupholisa ye-fiber futhi kusiza kakhulu ekudonsweni nasekulungisweni kwe-fiber. Ngakho-ke, ngokwanda kancane kancane kokushisa komoya oshisayo, ububanzi be-fiber buba buncane. Lapho i-fiber engenakubalwa ihlanganiswa ngokungahleliwe futhi iboshwe emishinini ye-mesh ukuze yakhe i-nonwovens encibilikisiwe, lapho i-fibers iba ncane kakhulu, kulapho kungenzeka khona ukuthi yakhe i-nonwovens ene-porosity ephezulu kanye nesakhiwo sendawo ethile ephezulu, futhi ubukhulu be-pore phakathi kwe-fibers buncane kakhulu. Ngakho-ke, ukusebenza kahle kokubanjwa kwezinhlayiya nakho kuphakeme.

Uma ama-nonwoven aqhunyiswe yi-PET melt blowed elungiswa ngendlela yokuqhunyiswe yi-melt, umfutho womoya oshisayo, izinga lokushisa lomoya oshisayo kanye ne-resin viscosity kunethonya elikhulu ezimpahleni zama-nonwoven aqhunyiswe yi-PET melt blowed. Ukwandisa umfutho womoya oshisayo kanye nezinga lokushisa kanye nokunciphisa i-viscosity ye-PET resin kuyasiza ekwakhekeni kwesakhiwo sefayibha enobubanzi obuncane futhi kuthuthukise ukusebenza kahle kokubanjwa kwezinhlayiya.

Lokhu okungenhla kungeniswa kwezimpawu ze-nonwovens ezipheshulwe nge-melt blown. Uma ufuna ukwazi kabanzi nge-nonwovens ezipheshulwe nge-melt blown, sicela ukhululeke ukuxhumana nathi.
