Ulayini wefilimu ophefumulayo unenqubo ye-extrusion efanayo neminye imigqa yefilimu yabalingisi, kodwa ifakwe iyunithi ye-MDO (ukuqondisa umshini).Igcwaliswe nge-appr.Amaphesenti angu-50% we-CaCo3, ifilimu inwetshwa iyunithi ye-MDO ukwenza izimbotshana ezincane ngaphakathi.Lezo zimbotshana ezincane ezixinene kakhulu kufilimu zivumela igesi noma umhwamuko ukuthi udlulise kodwa umise ukugeleza koketshezi.Ngakho ithola igama ngokuthi "ifilimu ephefumulayo".Izici zayo ezivelele azitholakali kuphela "ekuphefumuleni", kodwa futhi nasekuzizweni kwesandla okufana nendwangu, okwenza kube i-backsheet efanelekile ye-diaper ne-sanitary napkin.
Izinkambu eziyinhloko ezisetshenziswayo zamafilimu epulasitiki aphefumulayo zihlanganisa imikhiqizo yokunakekela inhlanzeko yomuntu siqu, imikhiqizo yokuzivikela yezokwelapha (njengomatilasi bezokwelapha, izingubo zokuzivikela, izingubo zokuhlinza, amashidi okuhlinza, ukuminyanisa okushisayo, imicamelo yezokwelapha, njll.), imigqa yezingubo, nezinsiza zokupakishwa kwemithi. .
Ulayini wokukhiqiza ifilimu ophefumulayo we-Wellson usebenzisa uhlelo olukhethekile lokulawula isikulufa se-bimetallic extrusion.Ngokwenza kahle ukwakheka kwesiteshi sokugeleza, kungathuthukisa kangcono izinga lokuncibilika kokuncibilika kanye nomthelela we-plasticizing wezinto ezingavuthiwe, futhi ihlangabezane nezidingo ezikhethekile zokukhishwa kwe-resin eluhlaza.Ngokwamukela idizayini yomgijimi elengayo esezingeni lomhlaba, inhloko ye-die head ezenzakalela ngokugcwele kanye nesistimu yokubona ukushuba okuzenzakalelayo nokulawula okunembayo okuphezulu kungalandelela ngempumelelo futhi ilawule ukufana okuvundlile nokuma kwefilimu, ngaleyo ndlela iqinisekise izinga layo eliphezulu. .Lokhu kubalulekile ukuze kuqinisekiswe ukucutshungulwa okulandelayo kanye nokwelula okungenazinkinga kwefilimu.
Ifilimu ephefumulayo isetshenziswa kakhulu kuleyo mikhakha efana nenabukeni lomntwana, i-sanitary napkin, izambatho zezokwelapha, kanye nolwelwesi olungangeni manzi ukuze kufakwe ngaphansi kophahla.

Ukuphawula: Abanye osayizi bemishini bayatholakala uma ucelwa.
I-1) Isistimu yokushisa yamafutha yeyunithi ye-MDO
2) Iyunithi ye-MDO enokwelula okuvundlile
3) Ukuqopha okujulile okuku-inthanethi kuyakhethwa.
4) Lamination in-line nge nonwoven uyazikhethela
