Ngokombono womqondo:
I-PC (i-Polycarbonate): Lena ipulasitiki engenambala, esobala ebukekayo futhi ebushelelezi. Ngenxa yemvelo yayo engenabuthi futhi engenaphunga, kanye nezakhiwo zayo ezinhle kakhulu zokuvinjwa kwe-UV kanye nokugcina umswakama, i-PC inebanga lokushisa elibanzi. Ihlala inganqamuki ku -180°C futhi ingasetshenziswa isikhathi eside ku-130°C, okuyenza ibe yinto ekahle yokupakisha ukudla.
I-PET (i-Polyethylene Terephthalate) : Lena into ecwebe kakhulu, engenambala, futhi ebonisa ngale eqine ngokwedlulele. Ibukeka njengengilazi, ayinaphunga, ayinambitheki futhi ayinabo ubuthi. Iyakwazi ukuvutha, ikhiqize ilangabi eliphuzi elinonqenqema oluluhlaza okwesibhakabhaka lapho lishiswa, futhi linezici ezinhle zokuvimbela igesi.
Ngokombono wezici nezinhlelo zokusebenza:
PC: Inokumelana nomthelela omuhle kakhulu futhi kulula ukuyibumba, ukuyivumela ukuthi yenziwe ibe amabhodlela, izimbiza, kanye nezimo zesitsha ezihlukahlukene zokupakisha uketshezi olufana neziphuzo, utshwala, nobisi. I-drawback eyinhloko ye-PC ukuthambekela kwayo ekucindezelekeni kokuqhekeka. Ukuze unciphise lokhu ngesikhathi sokukhiqiza, kukhethwa izinto ezingavuthiwe ezisezingeni eliphakeme, futhi izimo ezihlukahlukene zokucubungula zilawulwa ngokuqinile. Ukwengeza, ukusebenzisa ama-resin anengcindezi ephansi yangaphakathi, njengamanani amancane e-polyolefin, inayiloni, noma i-polyester ukuze kuhlanganiswe ukuncibilika, kungathuthukisa kakhulu ukumelana kwayo nokuqhekeka kwengcindezi nokumuncwa kwamanzi.
I-PET: Ine-coefficient ephansi yokunwetshwa kanye nezinga eliphansi lokuncibilika lokubumba elingu-0.2% kuphela, okuyingxenye eyodwa kweshumi ye-polyolefin futhi ephansi kune-PVC nenayiloni, okuholela ebukhulu obuzinzile bemikhiqizo. Amandla ayo emishini abhekwa njengangcono kakhulu, anezindawo zokunweba ezifana ne-aluminium. Amandla aqinile amafilimu ayo aphindwe kayisishiyagalolunye kunawe-polyethylene futhi aphindwe kathathu kunawe-polycarbonate nenayiloni, kuyilapho amandla awo okubamba aphindwe kathathu kuya kahlanu kunamafilimu ajwayelekile. Ukwengeza, amafilimu ayo anokuvimbela umswakama kanye nezindawo zokugcina iphunga. Kodwa-ke, naphezu kwalezi zinzuzo, amafilimu e-polyester ayabiza kakhulu, kunzima ukuwashisa, futhi ajwayele ugesi omile, yingakho engavamile ukusetshenziswa yedwa; zivame ukuhlanganiswa nama-resin anokuvalwa okungcono kokushisa ukuze enze amafilimu ayinhlanganisela.
Ngakho-ke, amabhodlela e-PET akhiqizwa kusetshenziswa inqubo yokubumba i-biaxial stretching blowing angasebenzisa ngokugcwele izici ze-PET, enikeza ukucaca okuhle, isicwebezelisi esiphezulu, nokubukeka okufana nengilazi, okuwenza amabhodlela epulasitiki afaneleka kakhulu ukufaka esikhundleni samabhodlela engilazi.
