Subizaimifuka ikozwe mubikoresho byinshi bya firime yoroheje, byumye cyangwa bifatanyirijwe hamwe kugirango bikore umufuka munini. Ibikoresho byo guhimba birashobora kugabanywamo ubwoko 9, nasubiramoumufuka wakozwe ugomba kuba ushobora guhangana nubushyuhe bwo hejuru hamwe nubushuhe butose. Igishushanyo mbonera cyacyo kigomba kandi kuba cyujuje ibyangombwa byo gufunga ubushyuhe bwiza, kurwanya ubushyuhe, kurwanya amazi, imbaraga nyinshi, no gukora inzitizi nyinshi.
1. PET firime
Filime ya BOPET ikorwa mugukuramo PET resin binyuze muri firime ya T no kurambura biaxically, ifite ibintu byiza cyane.
(1) Imikorere myiza yubukanishi. Imbaraga zingana za firime ya BOPET nimwe murwego rwo hejuru muri firime zose za plastiki, kandi ibicuruzwa bito cyane birashobora guhaza ibikenewe, hamwe no gukomera no gukomera.
(2) Kurwanya ubukonje nubushyuhe buhebuje. Ubushyuhe bukoreshwa bwa firime ya BOPET ni kuva kuri 70 kugeza kuri 150 ℃, ikomeza ibintu byiza byumubiri hejuru yubushyuhe bwagutse, bigatuma ikwiranye ninshi mubicuruzwa bipfunyika.
(3) Imikorere myiza ya barrière. Ifite imikorere myiza yo kurwanya amazi na gaze, bitandukanye na nylon, yibasiwe cyane nubushuhe. Igipimo cyacyo cyo kurwanya amazi gisa na PE, kandi coefficente yacyo ni nto cyane. Ifite inzitizi ndende ku mwuka n'impumuro, kandi ni imwe mu mpumuro nziza igumana ibikoresho.

2. Filime ya BOPA
Filime ya BOPA ni firime yo kurambura biaxial, ishobora kuboneka muguhina no kurambura biaxial icyarimwe. Firime irashobora kandi kuramburwa buhoro buhoro ikoresheje uburyo bwa T-mold yo gukuramo, cyangwa icyarimwe ikaramburwa ikoresheje uburyo bwo guhanagura. Ibiranga firime ya BOPA nibi bikurikira:
(1) Gukomera bihebuje. Imbaraga zingana, imbaraga zamarira, imbaraga zingaruka, nimbaraga zo guturika ya firime ya BOPA byose muribyiza mubikoresho bya plastiki.
.
.
(4) Ubushyuhe buringaniye, hamwe no gushonga bwa 225 ℃, kandi burashobora gukoreshwa igihe kirekire hagati ya -60 ~ 130 ℃. Imiterere yubukorikori bwa BOPA ikomeza guhagarara neza mubushyuhe buke kandi bwinshi.
(5) Imikorere ya firime ya BOPA yibasiwe cyane nubushuhe, cyane cyane mubijyanye no guhagarara neza hamwe ninzitizi. Nyuma yo kuba itose, firime ya BOPA muri rusange irambura kuruhande, usibye kubyimba. Kugabanya igihe kirekire, hamwe no kuramba kwa 1%.
3. Filime ya CPP
Filime ya CPP, izwi kandi nka firime ya polypropilene, ni firime idashobora kurambura, idafite icyerekezo cya polypropilene. Igabanijwe muri homopolymer CPP na copolymer CPP ukurikije ibikoresho fatizo. Ibikoresho nyamukuru byo guteka icyiciro cya CPP ni guhagarika kopolymer ingaruka irwanya polypropilene. Ibisabwa mu mikorere ni: ubushyuhe bworoheje bwa Vicat bugomba kuba hejuru yubushyuhe bwo guteka, kurwanya ingaruka bigomba kuba byiza, kurwanya hagati bigomba kuba byiza, kandi ijisho ry amafi hamwe na kristu bigomba kuba bike bishoboka.
4. Ifu ya aluminium
Aluminium foil nubwoko bwonyine bwicyuma mubikoresho byoroshye byo gupakira, bikoreshwa mugupakira ibintu hamwe nigihe kirekire cyo gusaba. Ifu ya aluminium ni icyuma gifite amazi atagereranywa, irwanya gaze, ikingira urumuri, hamwe nuburyo bwo kugumana uburyohe ugereranije nibindi bikoresho bipakira. Nibikoresho byo gupakira bidashobora gusimburwa rwose kugeza uyu munsi.
5. Ceramic evaporation coating
Ceramic vapor coating ni ubwoko bushya bwa firime yo gupakira, iboneka muguhumeka umwuka wa oxyde hejuru ya firime ya plastike cyangwa impapuro nka substrate mubikoresho bya vacuum. Ibiranga imyuka ya ceramic itwikiriye cyane harimo:
.
.
(3) Kugumana impumuro nziza. Ingaruka isa nugupakira ibirahuri, kandi ntabwo bizana umunuko nyuma yo kubika igihe kirekire cyangwa kuvura ubushyuhe bwinshi.
(4) Kubungabunga ibidukikije byiza. Ubushyuhe buke hamwe nibisigara bike nyuma yo gutwikwa.
6. Izindi firime zoroshye
(1) Ikaramu
Imiterere ya PEN isa na PET, kandi ifite ibintu bitandukanye bya PET, kandi hafi yabyo byose birarenze PET. Imikorere myiza yuzuye, imbaraga nyinshi, kurwanya ubushyuhe bwiza, gukora inzitizi nziza, no gukorera mu mucyo. Kurwanya UV idasanzwe ni ikintu kinini cyerekana PEN. Inzitizi ya PEN ku myuka y'amazi yikubye inshuro 3,5 iya PET, kandi inzitizi yayo ku myuka itandukanye ikubye inshuro enye PET.
(2) Filime ya BOPI
BOPI ifite ubushyuhe bwagutse cyane, kuva kuri -269 kugeza 400 ℃. Filime yarangije reaction ntigira aho ishonga, kandi ubushyuhe bwikirahure buri hagati ya 360 kugeza 410 ℃. Irashobora gukoreshwa mu kirere kuri 250 ℃ mu myaka irenga 15 nta mpinduka zikomeye zikorwa. BOPI ifite imikorere myiza yuzuye, imiterere yumubiri nubukanishi, irwanya imirasire, imiti irwanya imiti, ihindagurika ryimiterere, hamwe nubworoherane hamwe nubunini.
(3) Filime ya PBT
Filime ya PBT ni imwe muri firime ya thermoplastique polyester, aribyo firime ya butylene terephthalate. Ubucucike ni 1.31-1.34g / cm ³ point Ahantu ho gushonga ni 225 ~ 228 ℃, naho ubushyuhe bwikirahure ni 22 ~ 25 ℃. Filime ya PBT ifite imitungo isumba iyindi ugereranije na PET. PBT ifite ubushyuhe buhebuje, irwanya amavuta, kugumana impumuro nziza, hamwe nubushuhe bwo gufunga ubushyuhe, bigatuma bikenerwa no gupakira imifuka ikoreshwa mugukora ibiryo bya microwave. Filime ya PBT ifite inzitizi nziza kandi irashobora gukoreshwa mugupakira ibiryo biryoshye. Filime ya PBT ifite imiti irwanya imiti.
(4) Filime ya TPX
Filime ya TPX ikorwa na copolymerisation ya 4-methylpentene-1 hamwe na 2-olefin nkeya (3% ~ 5%), kandi ni plastike yoroheje ifite uburemere bwihariye bwa 0.83g / cm ³ ， Ibindi bikorwa nabyo ni byinshi cyane byiza. Byongeye kandi, TPX ifite imbaraga zo kurwanya ubushyuhe kandi ni ibikoresho birwanya ubushyuhe cyane muri polyolefine. Ifite kristu yo gushonga ya 235 ℃, imiterere myiza yubukanishi, modulus ndende kandi ndende ndende, kurwanya imiti ikomeye, kurwanya amavuta, kurwanya aside, alkali, namazi, hamwe no kurwanya hydrocarbone nyinshi. Irashobora kwihanganira ubushyuhe bugera kuri 60 ℃, ikarenza izindi plastiki zibonerana. Ifite umucyo mwinshi hamwe no kohereza 98%. Isura yayo irasobanutse neza, irimbisha, kandi ifite microwave ikomeye.
Niba ufite ibisabwa byose byo gusubiramo umufuka, urashobora kutwandikira. Nkumushinga wogupakira byoroshye mumyaka irenga 20, tuzatanga ibisubizo byukuri byo gupakira ukurikije ibicuruzwa byawe hamwe na bije.
