Mu myaka yashize, hari byinshi byiyongereyebyoroshyefirime zishobora kugororwa cyangwa kubumbabumbwa muburyo butandukanye kugirango zihuze inganda zitandukanye nikoranabuhanga.Izi filime zabonye porogaramu mu nganda nka electronics, kwerekana, imirasire y'izuba, hamwe no gupakira ubwenge, n'ibindi.Ubushobozi bwizi firime zunama zitabuze gukorera mu mucyo ningirakamaro kugirango batsinde muriyi porogaramu.Ariko ni mu buhe buryo izo filime zigera ku guhinduka?
Kugira ngo dusubize iki kibazo, dukeneye gucengera muburyo bwo gukora no gukora firime.Filime nyinshi zoroshye zibonerana zakozwe muri polymers, ni iminyururu ndende yo gusubiramo ibice bya molekile.Guhitamo ibikoresho bya polymer bigira uruhare runini muguhitamo guhinduka no gukorera mu mucyo.Bimwe mubikoresho bya polymer bisanzwe bikoreshwa muma firime yoroheje arimo polyethylene terephthalate (PET), polyethylene naphthalate (PEN), na polyimide (PI).
Ibikoresho bya polymer bitanga ibikoresho byiza byubukanishi, nkimbaraga zingana zingana hamwe no guhagarara neza, mugihe bikomeza gukorera mu mucyo.Iminyururu ya molekile ya polymer irapakiwe neza kandi itanga imiterere ikomeye kandi imwe kuri firime.Ubu busugire bwimiterere butuma firime ishobora kwihanganira kunama no kubumba bitavunitse cyangwa gutakaza umucyo.
Usibye guhitamo ibikoresho bya polymer, inzira yo gukora nayo igira uruhare muburyo bworoshye bwa firime.Filime isanzwe ikorwa hifashishijwe uburyo bwo gukuramo no kurambura.Mugihe cyo gukuramo, ibikoresho bya polymer byashongeshejwe hanyuma bigahatirwa binyuze mu gufungura gato bita gupfa, bikabigira urupapuro ruto.Uru rupapuro noneho rurakonja kandi rugakomera kugirango ukore firime.
Nyuma yuburyo bwo gukuramo, firime irashobora gutera intambwe ndende kugirango irusheho kunoza imiterere yayo.Kurambura bikubiyemo gukurura firime mubyerekezo bibiri perpendicular icyarimwe, ikagura iminyururu ya polymer ikayihuza mubyerekezo runaka.Ubu buryo bwo kurambura butangiza imihangayiko muri firime, byoroshye kunama no kubumba udatakaje umucyo.Urwego rwo kurambura hamwe nicyerekezo cyo kurambura rushobora guhinduka kugirango ugere kubyo wifuza muri firime.
Ikindi kintu kigira ingaruka kubushobozi bwo kugondafirime yorohejeni ubunini bwabo.Filime zoroheje zikunda guhinduka kurusha izibyimbye bitewe no kugabanuka kwabo kunama.Ariko, hariho ubucuruzi hagati yubunini nimbaraga za mashini.Filime yoroheje irashobora gukunda guturika cyangwa gutobora, cyane cyane iyo ikorewe ibihe bibi.Kubwibyo, abayikora bakeneye guhitamo ubunini bwa firime bashingiye kubisabwa byihariye.
Usibye imiterere yubukanishi nuburyo bwo gukora, gukorera muri firime biterwa nubuso bwayo.Iyo urumuri ruhuye nubuso bwa firime, birashobora kugaragara, kwanduzwa, cyangwa kwinjizwa.Kugirango ugere ku mucyo, firime ikunze gushyirwaho ibice bito byibikoresho bisobanutse, nka indium tin oxyde (ITO) cyangwa nanoparticles ya silver, ifasha kugabanya imitekerereze no kuzamura urumuri.Iyi myenda yemeza ko firime ikomeza kuba mucyo cyane nubwo yunamye cyangwa ibumba.
Usibye guhinduka kwabo no gukorera mu mucyo, firime yoroheje iboneka nayo itanga izindi nyungu nyinshi kurenza ibikoresho gakondo.Kamere yoroheje yabo ituma biba byiza mubikorwa aho kugabanya ibiro ari ngombwa, nko muri electronique yikuramo.Byongeye kandi, ubushobozi bwabo bwo guhuza nubuso bugoramye butuma igishushanyo cyibikoresho bishya kandi bizigama umwanya.Kurugero,firime yorohejeByakoreshejwe muburyo bugoramye, butanga uburambe bwo kureba.
Kwiyongera gukenewefirime yorohejeyateje imbere ubushakashatsi niterambere muriki gice, hamwe nabahanga naba injeniyeri baharanira kunoza imitungo yabo no kwagura ibikorwa byabo.Barimo gukora ibijyanye no guteza imbere ibikoresho bishya bya polymer hamwe no kurushaho guhinduka no gukorera mu mucyo, ndetse no gushakisha uburyo bwo gukora udushya kugira ngo umusaruro uhendutse.Nkibisubizo byizo mbaraga, ejo hazaza hasa nkicyizerefirime yoroheje, kandi turashobora kwitegereza kubona byinshi bishya mubikorwa bitandukanye.
Mu gusoza, guhinduka kwa firime zibonerana bigerwaho hifashishijwe ibintu byinshi, harimo guhitamo ibikoresho bya polymer, inzira yo gukora, ubunini bwa firime, nibiranga ubuso.Ibikoresho bya polymer bifite ibikoresho byiza byubukanishi byemerera firime kwihanganira kunama nta gutakaza umucyo.Ibikorwa byo gukora birimo gukuramo no kurambura kugirango turusheho kunoza imiterere.Ipitingi hamwe nuburyo bworoshye bikoreshwa kugirango bigabanye gutekereza no kongera urumuri.Hamwe nubushakashatsi niterambere bikomeje, ejo hazaza hafirime yorohejebirasa neza, kandi byashyizweho kugirango bihindure inganda nikoranabuhanga muburyo bwinshi.
