Nciphisa ifilimu, owaziwa nangokuthi ukugoqa okunciphile nomaukushisa shwabanisa ifilimu, iyinto yokupakisha eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene ukuvikela nokuvikela imikhiqizo ngesikhathi sokugcina nokuhamba.Yenziwe ngepulasitiki ye-polymer eshwabana iqine entweni eyimbozayo lapho ishiswa.Lokhu kudala iphakheji evikelekile futhi ebukeka kahle.Omunye wemithombo engcono kakhulu yokuthola ifilimu enciphayoizimboni zamafilimu zokupakisha.
Embonini yefilimu yokupakisha, inqubo yokukhiqiza ifilimu enciphayo ibandakanya izinyathelo eziningi.Nasi isifinyezo sendlela ifilimu eshwabene yefekthri yokupakisha yamafilimu enziwa ngayo.Okulandelayo, sizoxoxa kafushane ukuthi intengo yeukushisa shwabanisa ifilimu yokupakishaithengiswe ngqo ngumkhiqizi isethiwe.
Isinyathelo sokuqala senqubo yokukhiqiza ukwakha ingxube ye-polymer.Uhlobo oluvame kakhulu lwepulasitiki olusetshenziselwa ukwenza ifilimu enciphayo i-polyolefin, i-polymer ekwazi ukwelula futhi inciphe kalula.Izinto ezingavuthiwe zifakwa ku-hopper, lapho zincibilika futhi zixutshwe nezinye izithasiselo ukuze kunikezwe ifilimu izinto ezifiselekayo, njengokumelana ne-UV, ukumelana nokubhoboza noma ukukhanya.
Ngemva kokuba ingxube ye-polymer isilungisiwe, ifakwa ku-extruder, eshisa futhi ilolonge i-polymer ibe ishidi elincanyana, eliqhubekayo.Ishidi linganwetshwa noma liqondiswe ngezindlela ezihlukahlukene ukuze lithuthukise amandla alo kanye nokuvumelana nezimo.Ngemuva kwalokhu, ifilimu iyapholiswa futhi igoqwe kuma-spools amakhulu, ilungele ukucutshungulwa okwengeziwe.
Isinyathelo esilandelayo kwinqubo yokukhiqiza ukuphrinta ifilimu.Uma ifilimu enciphayo izophrintwa ngelogo, ulwazi lomkhiqizo, noma ezinye ihluzo, izodlula emshinini wokuphrinta ngaphambi kokuba igingqelwe kumqulu omncane.Lesi sinyathelo sidinga ukunemba nokunaka imininingwane ukuze kuqinisekiswe ukuphrinta okunembile nokungaguquguquki kuwo wonke umqulu wefilimu.
Ngemuva kokuphrinta, ifilimu ingaphansi kokwelashwa kokukhishwa kwe-corona ukuze kuthuthukiswe ukunamathela kwayo.Lesi sinyathelo sibalulekile ngoba sisiza ifilimu ukuthi ibambelele kangcono emkhiqizweni njengoba ishisa futhi incipha.Ngemuva kokucubungula, ifilimu isikwa ububanzi nobude obudingekayo, bese ihlanganiswa futhi ithunyelwe kumakhasimende.
Uma kufikaifilimu yokugoqa eqondile eya embonini, kunezici ezimbalwa ezisebenzayo.Izindleko zokukhiqiza izinto ezingavuthiwe, abasebenzi, kanye nezindleko eziphezulu konke kuthinta intengo yokugcina yefilimu eshwabene.Ngaphezu kwalokho, usayizi wefilimu, ukuqina kanye nezidingo zokuphrinta nazo zithinta izindleko.
Amakhasimende angonga imali ngokuthenga ifilimu enciphayo ngqo kuyoizimboni zamafilimu zokupakishangamanani angaphambili embonini.Ngokudlula abasabalalisi nabathengisi, amakhasimende angakwazi ukusebenzisa intengo yezitolo ezinkulu futhi akwazi ukuxoxisana ngedili elingcono ngokusekelwe ezidingweni zawo ezithile kanye nezidingo zevolumu.
Kafushane, ifilimu ye-shrink iyinto ebalulekile yokupakisha esetshenziswa ezimbonini ezahlukahlukene.Inqubo yokukhiqiza embonini yefilimu yokupakisha ihlanganisa izinyathelo eziningi, okuhlanganisa ukudala inhlanganisela ye-polymer, ukukhipha ifilimu, ukuphrinta, ukucubungula, ukusika nokupakisha.Ukuthengiswa okuqondile kwasefekthri kwefilimu yokupakisha ye-heat shrink kuthintwa izici eziningi, kodwa amakhasimende angonga imali ngokuthenga ngokuqondile kumkhiqizi.Lokhu kubasiza ukuthi bathole amafilimu ekhwalithi ephezulu ngamanani ancintisanayo.
