Kusuka ekubukeni komqondo:
I-PC (polycarbonate): Lesi yipulasitiki engenamibala, esobala ejabulisa ngobuhle futhi ebushelelezi. Ngenxa yendalo yayo engeyona yobuthi kanye nephunga, kanye nezakhiwo zayo ezinhle kakhulu ze-UV-blocking kanye nomswakama, i-PC inebanga lokushisa elibanzi. Ihlala ingafinyeleleki ku -180 ° C futhi ingasetshenziswa isikhathi eside ngo-130 ° C, okwenza kube yinto efanelekile yokupakishwa kokudla.
Pet (polyethylene terephthalate) : Lesi yi-Crystallines kakhulu, engenamibala, futhi ebonakalayo enzima kakhulu. Inokubukeka okufana nengilazi, ayinampule, ayinambitha, futhi ayinobuthi. Kuyavutha, kukhiqiza ilangabi eliphuzi elinonqenqemeni oluhlaza okwesibhakabhaka lapho lushisiwe, futhi lunezakhiwo ezinhle zokuvimba igesi.
Ngokombono wezimpawu kanye nezicelo:
PC: Inokumelana nomthelela omuhle kakhulu futhi kulula ukubumba, ukuvumela ukuthi kukhiqizwe amabhodlela, izimbiza, kanye nemidwebo ehlukahlukene yezitsha zokufaka iziphuzo ezinjengeziphuzo, utshwala nobisi. Ukubuyiselwa imali okuyinhloko kwe-PC kuyinto yokuqina kwayo ukugcizelela ukuqhekeka. Ukunciphisa lokhu ngesikhathi sokukhiqiza, kukhethwe izinto zokuhlanza okuphezulu okuphezulu, futhi izimo ezahlukahlukene zokucubungula zilawulwa ngokuqinile. Ngokwengeziwe, usebenzisa ama-resins ngengcindezi yangaphakathi ephansi, efana namanani amancane ama-polyolefins, i-nylon, noma i-polyester ngokuncibilikisa ukuxubana, kungathuthukisa kakhulu ukumelana kwayo ekuqhekekeni kwengcindezi nokumuncwa kwamanzi.
Thinta ngothando: Ine-coefficient ephansi yokunwetshwa kanye nesilinganiso esiphansi sokubumba amanani e-0,2% kuphela, okuyingxenye yeshumi e-polyolefins futhi ephansi kune-PVC ne-nylon, okuholela ekutheni kube nezinto ezinzile zemikhiqizo. Amandla ayo emishini abhekwa njengawe-Best, ngezakhiwo ezandiswa ezifana ne-aluminium. Amandla ashubile amafilimu alo anezikhathi eziyisishiyagalolunye ze-polyethylene kanye namahlandla amathathu e-polycarbonate ne-nylon, ngenkathi amandla awo anomthelela kungamafilimu amathathu kuya kwayisihlanu. Ngaphezu kwalokho, amafilimu awo anezakhiwo zomswakama kanye ne-Aroma Returnution Properties. Kodwa-ke, naphezu kwalezi zinzuzo, amafilimu we-polyester abiza kakhulu, kunzima ukushisa uphawu lwe-seal, futhi athambekele kugesi oqinile, yingakho asetshenziswa kaningi ngowodwa; Zivame ukuhlanganiswa nama-resins anokubekezela okungcono ukushisa ukudala amafilimu ahlanganisiwe.
Ngakho-ke, amabhodlela ezilwane zasekhaya akhiqizwa esebenzisa inqubo yokubumba evuthayo ye-biaxial angasebenzisa ngokuphelele izici zesilwane sasekhaya, enikeza ukucaca okuhle, ukucwebeza okuphezulu, nokubukeka okufana nengilazi, kubenza bavele amabhodlela epulasitiki afanelekile ukuze athathe amabhodlela epulazi.
