Umahluko phakathi kwe-PET kunye ne-PI yefilimu yokufudumeza yombane

I-PET kunye ne-PI yeyaba mabini efilimu yokufudumeza ngombane. Kodwa yintoni umahluko phakathi kwalo filimu yokufudumeza kombane kunye namanzi ahlukeneyo?
Okokuqala, masiqale ngokuqonda isilwanyana sasekhaya kunye ne-PI: I-PET sisifinyezo saseBritane kwi-Polythyene Terephthalate (PET) okanye i-PETP. I-Poly (Terephthalic Acid) iquka i-Poly (i-Ethylene Terephthaite) I-Dister Petter kunye ne-Poly (i-polynene Terephthaite). I-Poly (i-Ethylene Terephthalate) idla ngokubizwa ngokuba yi-Polyester Retin kwaye ihlala ibizwa ngokuba yi-polyester resin. Yi-prosances Polymer ye-Terephthayic i-Acid nase-Ethylene Glycol. Kunye ne-PBT yaziwa njenge-thermoplastic polyster okanye i-polyester egxunyekileyo.

I-Polymimide (Polymimide), idla ngokubizwa ngokuba yiPI ngesiTshayina, yi-heterocyclic colound equlathe ikhonkco elinemigangatho. Igama lesiNgesi Polylimide (PI) linokwahlulwa kuba ziintlobo ezine ze-PI: i-pi, i-pi, i-Polyamifimide (Pai) kunye nePolyetherimim (Pei).

Umahluko phakathi kwe-PET kunye ne-PI inokwahlulwahlulwahlulwa kwezi zinto zimbini zilandelayo:
Okokuqala, ukusuka kwindawo engaphandle kwefilimu: Ifilimu yokuthabatha yombane wezilwanyana zasekhaya yifilimu yokufudumeza, ngelixa ifilimu yokuthabatha yombane yifilimu ye-opaque yombane.
Okwesibini, umahluko wokunganyangeki kobushushu: Isilwanyana sasekhaya sinokufumana ifilimu yokufumana amanzi ngombane, sinokumelana neqondo lokushisa elisezantsi, ifilimu yokuthabatha yombane wezilwanyana zasekhaya inokuthi ifakwe I-thermostat, iqondo lobushushu lefilimu yokufudumeza izilwanyana ngama-50 + 5c. Ifilimu ye-PI yifilimu ephezulu yokufudumeza, inokusetyenziswa ixesha elide. Iqondo lobushushu lifikelela kwi-degrees engama-250, kodwa ngenxa yezizathu zokhuseleko, ukuseta okuqhelekileyo kweqondo lefilimu ye-PI yi-120 + 5 degrees celsius
