Indwangu ehlanganisiwe ye-polypropylene eyinhlanganisela ye-spunbond engalukiwe

Ngenxa yokwakheka kwe-saturated carbon single bond ye-polypropylene, ukwakheka kwayo kwamangqamuzana okuhlobene kuzinzile futhi kunzima ukuwohloka ngokushesha. Nakuba le ndwangu elula ye-polypropylene spunbond nonwoven iletha lula ukukhiqizwa nokuphila kwabantu, iphinde ibangele ukungcoliswa kwemvelo okuthile. Ngakho-ke, ukulungiswa nokucwaninga kwendwangu engalukwanga engalukiwe ye-polypropylene eyinhlanganisela ye-polypropylene eyinhlanganisela ye-spunbond ebaluleke kakhulu. I-Polylactic acid iyi-polymer e-biodegradable ene-biocompatibility enhle kakhulu kanye nezakhiwo zemishini. Ingahlanganiswa nezinto zokusetshenziswa ze-polypropylene ukuze kulungiswe izindwangu ze-polypropylene eziyinhlanganisela ye-spunbond nonwoven nonwoven biodegradable, ngaleyo ndlela kuncishiswe ukungcoliswa kwemvelo okubangelwa yi-polypropylene spunbond izindwangu ezingalukiwe.

Ukusebenza kwendwangu engalukiwe ye-polypropylene eyinhlanganisela ye-spunbond engalukiwe

Enqubweni yokulungisa i-biodegradable polypropylene composite spunbond nonwoven fabric, izici ezifana nesivinini sephampu yemitha, izinga lokushisa elishisayo eliginqikayo, nezinga lokushisa elijikelezayo kungaba nomthelela omkhulu ezimpahleni ezibonakalayo zendwangu engalukiwe ye-spunbond. Lungisa ngokuya ngezidingo zekhasimende ezifana nesisindo, ukujiya, amandla aqinile, njll.

Umthelela wejubane lephampu yemitha

Ngokusetha isivinini sephampu yemitha ehlukene, izici zefayibha zemicu yefayibha eyinhlanganisela elungisiwe, njengokuminyana komugqa, ububanzi befayibha, namandla okuphuka kwefayibha, ziyahlaziywa ukuze kutholwe isivinini sephampu yemitha elilungile ukuze kusebenze imicu yefayibha eyinhlanganisela elungisiwe. Ngasikhathi sinye, ngokusetha isivinini sephampu yemitha ehlukene ukuze kuhlaziywe izinkomba zokusebenza ezifana nesisindo, ukujiya, namandla aqinile endwangu ehlanganisiwe eyinhlanganisela ye-spunbond nonwoven, isivinini esilungile sepompo yemitha singatholwa ngokuhlanganisa izakhiwo zefiber kanye nezakhiwo ezingalukiwe zendwangu eyinhlanganisela ye-spunbond engalukiwe.

Umthelela wezinga lokushisa elishisayo

Ngokulungisa amanye amapharamitha wenqubo yokulungiselela kanye nokubeka izigayo eziginqikayo ezihlukene kanye namazinga okushisa okushisa okushisayo, umthelela wokushisa okushisa oshisayo ezimpahleni zemicu yefiber eyinhlanganisela elungisiwe iyafundwa futhi ihlaziywe. Uma izinga lokushisa elishisayo lokuqiniswa komshini wokugaya liphansi kakhulu, imicu egoqwayo ayikwazi ukuncibilika ngokuphelele, okuholela kumaphethini angacacile kanye nokungezwani kahle kwesandla. Ukuthatha ukulungiswa kwe-biodegradable polylactic acid/additive/polypropylene composite spunbond non-woven wendwangu njengesibonelo, uma izinga lokushisa elishisayo eliginqikayo lifinyelela ku-70 ℃, imigqa yefayibha eyinhlanganisela icacile futhi kunokunamathela kancane kumqulu, ngakho-ke umkhawulo wokushisa ongu-70 ℃ usufinyelele izinga lokushisa elingaphezulu.

Ithonya lokushisa lokuphotha

Umthelela wamazinga okushisa ahlukene okuphotha ezakhiweni zokuminyana kwentambo yefayibha eyinhlanganisela, ububanzi befayibha, namandla okuphuka kwefayibha, kanye nezakhiwo zendwangu ye-biodegradable polypropylene composite spunbond nonwoven, kuyilapho kulungiswa ezinye izinhlaka zenqubo yokulungiselela.

Ukugeleza kobuchwepheshe benqubo ye-biodegradable polypropylene composite spunbond nonwoven fabric

(1) Sika i-polylactic acid, i-polypropylene, ne-maleic anhydride graft copolymer futhi ukuhlanganise ngezilinganiso ezifanele;

(2) Sebenzisa i-extruder ukuze uthole imbudumbudu kanye nomshini wokuphotha ukuze uphothe;

(3) Hlunga ngesihlungi esincibilikayo bese wenza i-mesh ngaphansi kwesenzo sephampu yemitha, isomisi esishisayo, kanye nokwelula komoya okugeleza okuhamba ngesivinini esiphezulu;

(4) Khiqiza izindwangu ezifanelekile ze-spunbond ezingalukiwe ngokusebenzisa i-hot rolling bonding reinforcement, i-winding, kanye nokusikwa kokuhlehla.
