Amafilimu ahlukahlukene ajwayele ukusetshenziswa empilweni yansuku zonke. Yiziphi izinto zokwakha amafilimu azenziwe ngawo? Yiziphi izici zokusebenza ngakunye? Lokhu okulandelayo ukwethulwa okuningiliziwe kwamafilimu epulasitiki asetshenziswa kakhulu empilweni yansuku zonke:
Ifilimu lepulasitiki liyifilimu eyenziwe nge-polyvinyl chloride, i-polyethylene, i-polypropylene, i-polystyrene namanye ama-resins, esetshenziselwa ukupakisha, njll.
Ifilimu yepulasitiki ingahlukaniswa
Ifilimu ye -Industrial: ifilimu elishaywayo, ifilimu elithambile, ifilimu eleluliwe, ifilimu le-cast, njll;
- Ifilimu le-Ezolimo Eletheli, ifilimu ye-mulch, njll;
-Films yokufaka (kufaka phakathi amafilimu ahlanganisiwe wokupakishwa kwemithi, amafilimu ahlanganisiwe wokupakishwa kokudla, njll.).
Izinzuzo kanye nokubi kwefilimu yepulasitiki:
Izici zokusebenza kwamafilimu aphambili epulasitiki:
Ifilimu le-piaxed plypropylene (BOPP)
I-Polypropylene iyi-resin ye-thermoplastic resin ekhiqizwa yi-polymerization ye-propylene. Izinto ze-Copolymer PP zinokushisa okuphansi kokushisa okuphansi (okungu-100 ° C), ukucaca okuphansi, isicwebezelisi esiphansi, kanye nokuqina okuphansi, kepha amandla aphansi, futhi amandla we-PP anamandla, futhi amandla anomthelela we-PP ayanda ngokuqukethwe kwe-ethylene. Amazinga okushisa athambile we-PP ayi-150 ° C. Ngenxa yesilinganiso esiphakeme se-crystallity, lokhu okuqukethwe kunokuqina okuhle kakhulu komhlaba kanye nezakhiwo zokumelana nokwehlela. I-PP ayinayo izinkinga zokuqhekeka kwengcindezi yemvelo.
Ifilimu le-pilypropylene elisezingeni eliphakeme (i-BOPP) liyinto eguqukayo yokupakisha eguqukayo eyenziwe ngawo-1960s. Isebenzisa umugqa okhethekile wokukhiqiza ukuze uhlanganise izinto zokwakha i-polypropylene eluhlaza kanye nezithasiselo ezisebenzayo, zincibilike futhi zixoxile zibe ngamashidi, bese ziyelula kumafilimu. Kusetshenziswa kabanzi ekuphaketheni kokudla, uswidi, ugwayi, itiye, ujusi, ubisi, izindwangu, njll., Futhi inedumela "lokufaka iNdlovukazi". Ngaphezu kwalokho, futhi futhi lungasetshenziswa kulungiselelo lwemikhiqizo esebenza ngenani eliphakeme efana nolwelwesi lukagesi kanye nolwelwesi olungama-microporous, ngakho-ke amathemba wokuthuthuka kwamafilimu e-BOPP abanzi kakhulu.
Ifilimu le-BOPP aligcini nje ngokuba nezinzuzo zobukhulu obuphansi, ukumelana kahle nokugqwala okumnandi nokuphikiswa okuhle kokushisa kwe-PP resin, kepha futhi kunezakhiwo ezinhle ze-optical, amandla aphezulu okuqukethwe okucebile kwezinto ezisetshenziswayo. Ifilimu le-BOPP lingahlanganiswa nezinye izinto ezinezakhiwo ezikhethekile ukuze zithuthukise noma zithuthukise ukusebenza. Izinto ezisetshenziswayo ezisetshenziswayo zifaka ifilimu ye-PE, i-orivating polypropylene (CPP) ifilimu, i-polyvinylidene chloride (PVDC), ifilimu ye-aluminium, njll.
Ifilimu eliphansi eliphansi polyethylene film (LDPE)
Ifilimu le-polyethylene, okungukuthi i-PE, inezici zokumelana nomswakama kanye nomswakama ophansi wokuqina.
I-Low-density polyethylene (LPDE) iyi-resin yokwenziwa i-resin etholwe yi-ethylene radical polymerization ngaphansi kwengcindezi ephezulu, ngakho-ke iphinde ibizwe ngokuthi "i-polyethylene ephezulu". I-LPDE i-molecule efakwe ngamagatsha ubude obuhlukile ku-main chain, eno-15 kuye kwangama-30 ethyl, ama-butyl noma amagatsha amade kuma-athomu wekhabhoni ayi-1000 eketani elikhulu. Ngoba i-chain yama-molecular iqukethe amaketanga amade futhi amafushane afakwe ngamafutheni, umthamo unawo ama-density aphansi, ukumelana okuphansi, ukumelana kahle kwamakhemikhali, ukuqina okuqinile kwe-oxidizing (ngaphandle kokuqina komoya, ukuqina kukasawoti, kunezindawo ezinhle zokufakelwa kukagesi. I-Translucent futhi icwebezelayo, inokuqina okuhle kwamakhemikhali, ukuncipha kokushisa, ukumelana kwamanzi kanye nokumelana komswakama, ukumelana nokuqhwala, futhi kungabiliswa. Ububi balo obukhulu buyisithiyo sabo esimpofu ku-oksijini.
Imvamisa isetshenziswa njengefilimu yangaphakathi yesendlalelo yezinto zokwenziwa eziguqukayo eziguqukayo, futhi futhi iyifilimu esetshenziswa kabanzi futhi esetshenziswa kakhulu yepulasitiki njengamanje, i-accounting for ezingaphezu kwama-40% zokusetshenziswa kwamafilimu okupakisha epulasitiki. Kunezinhlobo eziningi zamafilimu okupakisha i-polyethylene, futhi imisebenzi yawo nayo ihlukile. Ukusebenza kwefilimu elingqimba elilodwa akushadile, futhi ukusebenza kwefilimu eyinhlanganisela kuyahambisana. Kuyinto ebaluleke kakhulu yokupakishwa kokudla. Okwesibili, ifilimu ye-polyethylene nayo isetshenziswa emkhakheni wobunjiniyela bomphakathi, njengeGeomembrane. Isebenza njenge-materproof in engineering yomphakathi futhi ine-permeability ephansi kakhulu. Ifilimu yezoLimo isetshenziswa kwezolimo, ezingahlukaniswa nge-Shed Shed Film, ifilimu le-mulch, ifilimu elinomunyu, ifilimu yokugcina eluhlaza nokunye.
Ifilimu le-Polyester (Pet)
Ifilimu le-Polyester (Pet), elaziwa ngokuthi i-polyethylene terephthalate, iyipulasitiki yobunjiniyela be-thermoplastic. Kuyinto ebonakalayo yefilimu eyenziwe ngamashidi aminyene ngokukhishwa bese yelulwa kakhulu. Ifilimu le-polyester libonakaliswa yizakhiwo ezinhle kakhulu zemishini, ukuqina okukhulu, ukuqina nobulukhuni, ukumelana nokushisa okuphezulu, ukumelana kwamazinga okushisa, ukumelana namafutha, ukuqina komoya kanye nokugcinwa komoya kanye nokugcinwa komoya. Enye yezinto ezihlanganisiwe zefilimu ezihlanganisiwe, kepha ukumelana kwe-corona akukuhle.
Intengo yefilimu ye-polyester iphakeme kakhulu, futhi ubukhulu bawo bungu-0,12 mm. Imvamisa isetshenziswa njengento engaphandle yokupakishwa kokudla kwamaphakeji, futhi inokuphrinta okuhle. Ngaphezu kwalokho, ifilimu le-polyester livame ukusetshenziswa njengokuphrinta nokupakisha okudlayo okufana nefilimu lokuvikela imvelo, ifilimu elimhlophe, futhi kusetshenziswa kabanzi ezimbonini ezifana nezimpawu ze-fiber eziqinisiwe, izinto zokwakha, kanye nomuthi kanye nempilo.
Ifilimu lePulastiki leNylon (ony)
Igama lamakhemikhali le-nylon yi-polyamide (PA). Njengamanje, kunezinhlobo eziningi ze-nylon ezikhiqizwayo, futhi izinhlobo eziyinhloko ezisetshenziselwa ukukhiqiza amafilimu yi-nylon 6, i-nylon gloss, nokuphikiswa okuphezulu, ukumelana nokulimala okuphezulu, ukumelana kawoyela kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa kwe-organic kanye nokuphikiswa komoya. Ukumelana Nokugqoka Okuhle Kakhulu kanye nokumelana kwe-puncture, okuthambile okuthambile, kepha izithiyo ezinhle kakhulu ze-oksijini, ukudonsa okuphezulu komswakama, ukudla okushisayo komswakama, ukudla okunomswakama, ukudla okuthosiwe, ukudla okwenziwe nge-vacum, njll.
I-Cast Polypropylene film (CPP)
Ngokungafani nenqubo ye-polypropylene yefilimu ye-polypropylene yefilimu (i-BOPP), i-polypropylene film (CPP) ifilimu elingemuva elingalinganiswanga, elingezinhle, elingathathelwanga elikhiqizwa ngokuncibilika ukulahla nokucishwa. Kuboniswa ngejubane lokukhiqiza elisheshayo, okuphuma okuphezulu, ukuvezwa kwefilimu okuhle, ukufana, ukufana, ukulingana okuhle, nokulinganisela okuhle kwezindawo ezahlukahlukene. Ngoba ifilimu eyisicaba, umsebenzi wokulandela njengokuphrinta nokuhlanganisa kulula kakhulu. I-CPP isetshenziswa kabanzi ekuphaketheni kwezindwangu, izimbali, ukudla kanye nezidingo zansuku zonke.
Ifilimu lepulasitiki le-aluminium
Ifilimu e-Aluminised inezimpawu zombili zefilimu yepulasitiki kanye nezimpawu zensimbi. Iqhaza le-aluminium plating ebusweni befilimu livikela ukukhanya futhi livikele imisebe ye-ultraviolet, ngaphandle kokulungiselela impilo yeshede yokuqukethwe, kepha futhi ithuthukisa ukukhanya kwefilimu. Ngakho-ke, ifilimu eli-Aluminised lisetshenziswa kabanzi ekuphangethweni okuhlanganisiwe, ikakhulukazi ezisetshenziswa ngokupakishwa kokudla owomile nokhukhumezekile njengamabhisikidi, kanye nokupakishwa kwangaphandle kweminye imithi nezimonyo.
