Izixazululo Zokubuyiswa Kwamalangabi Zamafilimu Eshidi Le-PET

Ikhasimende likhiqiza amafilimu eshidi le-PET angavimbeli ilangabi anogqinsi ukusuka ku-0.3 kuya ku-1.6 mm, lisebenzisa i-hexaphenoxycyclotriphosphazene (HPCTP) futhi lifuna ukuncishiswa kwezindleko. Ngezansi kukhona ukwakheka okunconyiwe nokuhlaziya okuningiliziwe kwamafilimu e-PET angavimbeli ilangabi:

1. Ukuhlaziywa Kokukhetha Okubuyiswa Kwelangabi

I-Hexaphenoxycyclotriphosphazene (HPCTP)

• Izinzuzo: Ama-flame retardants asuselwa ku-Phosphazene ahlakazeka kahle ku-PET, agcina ukubonakala okuphezulu. Indlela evimbe amalangabi ihlanganisa ukushaja kwesigaba esijiyile kanye nokucupha okunamandla kwesigaba segesi, okuyenza ifanele amafilimu abonisa ngale.
• Umthamo: Kunconywe ku-5% -10%. Amanani eqile angase athinte izakhiwo zemishini.
• Izindleko: Ziphezulu ngokuqhathaniswa, kodwa izindleko eziphelele zihlala zilawuleka ekulayisheni okuphansi.

I-Aluminium Hypophosphite

• Ukungalungi: Izimpushana ezingaphili zingadala inkungu, ziphazamise ukubonakala. Usayizi wezinhlayiyana ocwebe kakhulu noma ukulungiswa kwendawo kungadingeka ukuze kusetshenziswe okungenzeka.
• Ukusebenza: Akunconyiwe yedwa; ingahlanganiswa ne-HPCTP ukuze kwehliswe izindleko zizonke (ukuhlola obala kuyadingeka).

2. Izinketho Zokwakha Ezinconyiwe

Inketho 1: Uhlelo olulodwa lwe-HPCTP

• Ukwakhiwa: 8% -12% HPCTP + PET base material.
• Izinzuzo: Ukukhanya okuphezulu nokusebenza kahle kwe-flame-retardant (kungafinyelela i-UL94 VTM-2 noma i-VTM-0).
• Isilinganiso Sezindleko: Ekulayisheni okungu-10%, ukukhuphuka kwezindleko ngekhilogramu ye-PET cishe ku-¥10 (¥100/kg × 10%).

Inketho 2: I-HPCTP + Aluminium Hypophosphite Blend

• Ukwakhiwa: 5% HPCTP + 5% -8% aluminium hypophosphite + PET base material.
• Izinzuzo: Ukwehliswa kwezindleko, nge-aluminium hypophosphite esiza ekubambezelekeni komlilo wesigaba segesi, okungenzeka kunciphise ukusetshenziswa kwe-HPCTP.
• Qaphela: Ukucaca kufanele kuhlolwe (i-aluminium hypophosphite ingase ibangele inkungu encane).

3. Izincomo Zokucubungula Nokuhlola

• Inqubo Yokusabalalisa: Sebenzisa i-twin-screw extruder ukuze uqinisekise ukuhlakazeka okufanayo kwama-flame retardants futhi ugweme i-agglomeration ephazamisa ukubonakala.
• Ukuhlolwa Kokubuyiswa Kwelangabi: Linganisa ngokwezinga le-UL94 VTM noma I-Oxygen Index (OI), uqondise ku-OI > 28%.
• Ukuhlolwa Kokungafihli: Kala inkungu usebenzisa imitha yehaze, uqinisekise ukuthi inkungu <5% (ugqinsi lwefilimu: 0.3-1.6 mm).

4. Ukuqhathaniswa Kwezindleko

Ithebula Lokulayishwa Kwe-Flame Retardant kanye Nokwenyuka Kwezindleko

5. Isiphetho

• Inketho Ekhethwayo: I-HPCTP iyodwa ku-8% -10%, ukulinganisa obala kanye nokuncipha komlilo.
• Enye Inketho: Ingxube ye-HPCTP ne-aluminium hypophosphite, edinga ukuqinisekiswa kokusobala kanye nemiphumela ye-synergistic.

Okutuswayo: Ikhasimende kufanele lenze uvivinyo oluncane kuqala, ligxile ekubambezeleni ilangabi (UL94/OI) nokuhlola inkungu, bese lilungiselela ukwakheka nenqubo. Uma kudingeka okunye ukuncishiswa kwezindleko, hlola i-aluminium hypophosphite eguquliwe phezulu noma amanoveli e-phosphorus-based flame retardants.
