Ifilimu ephefumulayo yenziwe nge-polyethylene resin (PE) njengesithwali, ingeza izihlungi ezinhle (ezifana ne-CaC03) futhi ziyikhiphe ngokuphonsa indlela yokubumba yokupholisa.Ngemuva kokwelula isikhathi eside, ifilimu inesakhiwo esiyingqayizivele se-microporous.Lawa ma-micropores akhethekile ane-high density distribution awakwazi nje ukuvimba ukuvuza koketshezi, kodwa futhi avumele ama-molecule egesi afana nomhwamuko ukuba adlule.Ngaphansi kwezimo ezijwayelekile, izinga lokushisa lefilimu liyi-1.0-1.5 ° C eliphansi kunefilimu engaphefumuli, futhi isandla sizwakala sithambile futhi amandla okukhangisa anamandla.
Njengamanje, izinkambu eziyinhloko ezisetshenziswayo zamafilimu epulasitiki aphefumulayo zifaka imikhiqizo yokunakekelwa kwenhlanzeko yomuntu siqu, imikhiqizo yokuzivikela yezokwelapha (njengamatilasi wezokwelapha, izingubo zokuzivikela, izingubo zokuhlinza, amashidi okuhlinza, ukuminyanisa okushisayo, imicamelo yezokwelapha, njll.), imigqa yezingubo, nezinsiza. emaphaketheni emithi.Ukuthatha imboni yemikhiqizo yokunakekelwa kwenhlanzeko yomuntu siqu njengesibonelo, izingxenye zomzimba womuntu ukuthi le mikhiqizo zihlangana nazo kulula ukuzalanisa amagciwane ahlukahlukene ngenxa yomswakama.Imikhiqizo eyenziwe ngamakhemikhali e-fiber textile materials inomoya omubi, ukuze umswakama okhishwe isikhumba awukwazi ukumuncwa futhi uhwamuke, okuholela ekushiseni okudlulele, okungagcini nje ukunciphisa induduzo, kodwa futhi kukhuthaze kalula ukukhiqizwa kwamagciwane futhi kuvuselele isikhumba.Ngakho-ke, ukusetshenziswa kwezinto eziphefumulayo ukwandisa ukoma nokunethezeka kwendawo yesikhumba kuye kwaba enye yezindlela ezibalulekile ekuthuthukisweni kwemboni yanamuhla yemikhiqizo yokunakekelwa komuntu siqu.
Ifilimu yepulasitiki ephefumulayo ivumela umhwamuko wamanzi ukuba udlule ngaphandle kokuvumela amanzi awuketshezi ukuba adlule, futhi ikhipha umhwamuko wamanzi ongqimbeni olubambayo lwemikhiqizo yokunakekelwa kwenhlanzeko ngokusebenzisa ifilimu ukugcina ungqimba oluthinta isikhumba lomile kakhulu, okwenza ubuso besikhumba bome futhi. ngempumelelo kakhudlwana.Ivimbela ukukhula kwamagciwane futhi iqinise ukuvikelwa kwesikhumba.Ngaphezu kwalokho, ukuthamba kwayo okufana nosilika akuhambisani nezinye izinto ezifanayo njengamanje.
Njengefilimu engezansi yemikhiqizo yokunakekelwa kwezempilo, ifilimu ephefumulayo isetshenziswe kabanzi eYurophu, eMelika, eJapane, eNingizimu Korea, eMpumalanga Ekude kanye nasezifundeni zezwe lami zaseHong Kong naseTaiwan.Kwezinye izingxenye zomhlaba, ngokuthuthukiswa okuqhubekayo kwezinga lokuphila kwabantu eminyakeni yamuva, ukukhiqizwa nokusetshenziswa kwamafilimu epulasitiki aphefumulayo kuye kwanda unyaka nonyaka.Akugcinanga nje ngokukhulisa ukunakwa ekuvikelweni kwempilo kamama nezinsana, kodwa futhi kwakhuthaza ukusetshenziswa kwamafilimu epulasitiki aphefumulayo.
