Kapangidwe ka zinthu zofunika kwambiri m'bokosi la ma CD a PET:
PET ndi polima yoyera ngati mkaka kapena yachikasu yopepuka yokhala ndi kristalo yokhala ndi pamwamba posalala komanso kowala. Yokhazikika bwino, yocheperako komanso yolimba kwambiri, yokhala ndi kulimba kwakukulu ngati thermoplastics: yoteteza bwino magetsi, yosagwirizana ndi kutentha. Yopanda poizoni, yolimbana ndi nyengo, yonyowa madzi pang'ono.
Ubwino wa bokosi la ma CD a PET:
1. Ili ndi mphamvu zabwino zamakina, mphamvu ya kukhudza ndi nthawi 3-5 kuposa mafilimu ena, kukana bwino kupindika;
2. Ndi kukana kutentha kwambiri komanso kotsika, ingagwiritsidwe ntchito kutentha kwa 120℃ kwa nthawi yayitali.
Kugwiritsa ntchito kwakanthawi kochepa kumatha kupirira kutentha kwa 150℃, kumatha kupirira kutentha kwa -70℃ kochepa, ndipo kutentha kwapamwamba ndi kotsika sikukhudza kwambiri mphamvu zake zamakanika;
4. Mpweya ndi nthunzi ya madzi sizilowa bwino, komanso zimalimbana bwino ndi mpweya, madzi, mafuta ndi fungo;
5. Kuwonekera bwino, kumatha kuletsa kuwala kwa ultraviolet, kunyezimira bwino;
6. Sizowopsa, zopanda kukoma, thanzi labwino komanso chitetezo, zitha kugwiritsidwa ntchito mwachindunji popangira chakudya.
PET imagwiritsidwa ntchito kwambiri mu ulusi, filimu ndi pulasitiki waukadaulo. Ulusi wa PET umagwiritsidwa ntchito kwambiri mumakampani opanga nsalu. Filimu ya PET imagwiritsidwa ntchito kwambiri muzinthu zamagetsi zotetezera kutentha, monga ma capacitor, kutchinjiriza chingwe, substrate ya waya wosindikizidwa, kutchinjiriza ma electrode groove ndi zina zotero. Gawo lina lomwe filimu ya PET imagwiritsidwa ntchito ndi wafer base ndi band, monga filimu yoyenda, filimu ya X-ray, tepi yomvera, tepi yamagetsi ya kompyuta, ndi zina zotero. Filimu ya PET imagwiritsidwanso ntchito kusamutsa aluminiyamu mu filimu yachitsulo, monga waya wagolide ndi siliva, filimu ya micro capacitor, ndi zina zotero. Filimuyi ingagwiritsidwe ntchito pazakudya zamitundu yonse, mankhwala, zinthu zopanda poizoni zosungiramo aseptic. PET yolimbikitsidwa ndi ulusi wagalasi ndi yoyenera mafakitale amagetsi ndi zamagetsi komanso magalimoto, yomwe imagwiritsidwa ntchito m'maselo osiyanasiyana a coil, transformer, TV, zida zojambulira ndi chipolopolo, chogwirira nyali zamagalimoto, lampshade, chogwirira nyali yoyera yotentha, zolumikizira, chowongolera kuwala kwa dzuwa, ndi zina zotero.
Mabokosi a PET ndi njira yabwino kwambiri. Pa moyo watsiku ndi tsiku, pali kufunika kwakukulu kwa kugwiritsa ntchito mabokosi opaka ma PET. Opanga ambiri ndi ogula amagwiritsa ntchito mabokosi opaka ma PET pokonza ndi kupanga, ndipo kufunika kwa mabokosi opaka ma PET pa moyo watsiku ndi tsiku n'kokwera kwambiri. Kapangidwe ndi kugwiritsa ntchito kwa mabokosi opaka ma PET pamwambapa.
