Shrink firimu, inozivikanwawo sekuti shrink wrap kanakupisa kupisa firimu, chinhu chakasiyana-siyana chekurongedza chinoshandiswa mumaindasitiri akasiyana siyana kuchengetedza nekuchengetedza zvigadzirwa panguva yekuchengetedza nekufambisa.Yakagadzirwa nepurasitiki yepolymer inodzika zvakasimba kune chinhu chainovhara kana ichipisa.Izvi zvinogadzira yakachengeteka uye inyanzvi-inotaridzika pasuru.Imwe yeakanakisa masosi ekutora shrink firimu ndeyekurongedza mafirimu mafekitori.
Mufekitari yekurongedza firimu, iyo nzira yekugadzira ye shrink firimu inosanganisira akawanda matanho.Heino tarisiro yemagadzirirwo anoita iyo shrink firimu repacking film fekitori.Zvadaro, tichakurukura muchidimbu kuti mutengo wekupisa shrink kurongedza firimuinotengeswa zvakananga nemugadziri akaiswa.
Nhanho yekutanga mukugadzira maitiro ndeyekugadzira musanganiswa wepolymer.Mhando yepurasitiki inonyanya kushandiswa kugadzira firimu re shrink polyolefin, polymer inogona kutambanudza uye kuderera nyore nyore.Iyo mbishi inoiswa muhopi, iyo inonyungudutswa uye yakasanganiswa nezvimwe zvinowedzera kuti ipe iyo firimu zvinhu zvinodikanwa, seUV resistance, puncture resistance kana kujeka.
Mushure mekunge musanganiswa wepolymer wagadzirwa, unodyiswa mune extruder, iyo inopisa uye inoumba iyo polymer kuita pepa rakatetepa, rinoramba riripo.Iyo shiti inogona kutambanudzwa kana kutariswa munzira dzakasiyana siyana kuwedzera simba rayo uye kushanduka.Mushure meizvi, iyo firimu inotonhorera uye yakakungurutswa pahombe spools, yakagadzirira kuenderera mberi.
Nhanho inotevera mukugadzirwa kwekugadzira ndeyekudhinda firimu.Kana iyo shrink firimu ichizodhindwa ine logo, ruzivo rwechigadzirwa, kana mamwe magirafu, ichapfuura nemuchina wekudhinda isati yakungurutswa padiki roll.Iyi nhanho inoda kunyatsojeka uye kutarisisa kune zvakadzama kuti ive nechokwadi chekudhinda kwakaringana uye kunoenderana pane yega roll yefirimu.
Mushure mekudhinda, iyo firimu inoiswa kune corona discharge kurapwa kuti ivandudze kunamatira kwayo.Iyi nhanho yakakosha sezvo ichibatsira iyo firimu kunamatira zvirinani kune chigadzirwa sezvo ichipisa uye ichiderera.Mushure mekugadzirisa, firimu inochekwa kusvika pahupamhi hunodiwa uye urefu, uye inoputirwa uye inotumirwa kune vatengi.
Kana zvasvikayakananga-ku-factory shrink wrap film, zvinhu zvakawanda zvinobatanidzwa.Mutengo wekugadzira zvigadzirwa, vashandi, uye pamusoro zvese zvinokanganisa mutengo wekupedzisira weiyo shrink firimu.Mukuwedzera, saizi yefirimu, ukobvu uye kudhinda zvinodiwa zvinokanganisawo mutengo.
Vatengi vanogona kuchengetedza mari nekutenga shrink firimu zvakananga kubvakurongedza mafirimu mafekitoripamitengo yekare yefekitari.Nekupfuura vagovanisi nevatengesi, vatengi vanogona kutora mukana wekutengesa mitengo uye nekugona kutaurirana chibvumirano chiri nani zvichienderana nezvavanoda uye vhoriyamu zvinodiwa.
Muchidimbu, shrink firimu chinhu chakakosha chekurongedza chinoshandiswa mumaindasitiri akasiyana.Maitiro ekugadzira mune yekurongedza firimu chirimwa anosanganisira akawanda matanho, anosanganisira kugadzira polymer musanganiswa, extruding firimu, kudhinda, kugadzirisa, kucheka uye kurongedza.Fekitari yakananga kutengesa kwekupisa shrink kurongedza firimu kunokanganisa nezvakawanda zvinhu, asi vatengi vanogona kuchengetedza mari nekutenga zvakananga kubva kumugadziri.Izvi zvinovabatsira kuwana emhando yepamusoro shrink mafirimu pamitengo yemakwikwi.
