Izisombululo ezithintela ilangatye kwiifilimu zephepha lePET

Umthengi uvelisa iifilimu zePET ezibonisa ukukhanya okungabonakaliyo ezinobukhulu obuqala kwi-0.3 ukuya kwi-1.6 mm, esebenzisa i-hexaphenoxycyclotriphosphazene (HPCTP) kwaye ufuna ukunciphisa iindleko. Apha ngezantsi kukho iindlela ezicetyiswayo kunye nohlalutyo oluneenkcukacha lweefilimu zePET ezibonisa ukukhanya okubonakalayo okubonakalayo okubonakalayo:

1. Uhlalutyo loKhetho oluBandakanya iLanga

I-Hexaphenoxycyclotriphosphazene (HPCTP)

• Iingenelo: Izinto ezithintela ilangatye ezisekelwe kwiPhosphazene zisasazeka kakuhle kwiPET, zigcina ukukhanya okuphezulu. Indlela yokusebenza ethintela ilangatye ibandakanya ukutsha kwesigaba esidityanisiweyo kunye nokubamba igesi nge-radical, nto leyo eyenza ukuba ifaneleke kwiifilimu ezibonisa ukukhanya.
• Umlinganiselo: Kucetyiswa ukuba ube yi-5%-10%. Ubungakanani obugqithisileyo bunokuchaphazela iimpawu zoomatshini.
• Ixabiso: Liphezulu kakhulu, kodwa ixabiso lilonke lihlala lilawuleka xa umthwalo uphantsi.

I-Aluminium Hypophosphite

• Iingxaki: Iipowder ezingezizo zendalo zinokubangela inkungu, nto leyo echaphazela ukucaca. Ubungakanani beentwana ezincinci kakhulu okanye ukuguqulwa komphezulu kunokufuneka ukuze kusetyenziswe.
• Ukusetyenziswa: Akukhuthazwa kuphela; ingaxutywa ne-HPCTP ukunciphisa iindleko zizonke (kufuneka uvavanyo lokungafihlisi).

2. Iindlela ezicetyiswayo zoKwakha

Ukhetho 1: Inkqubo ye-HPCTP enye

• Ukwenziwa: 8%-12% HPCTP + PET izinto ezisisiseko.
• Iingenelo: Ukukhanya okugqibeleleyo kunye nokusebenza kakuhle okubangela ukuba ilangabi lingabi namandla (kunokufikelela kwi-UL94 VTM-2 okanye kwi-VTM-0).
• Uqikelelo lweendleko: Xa ulayisha nge-10%, ukunyuka kweendleko ngekhilogram nganye yePET kumalunga ne-¥10 (¥100/kg × 10%).

Ukhetho 2: HPCTP + Aluminium Hypophosphite Blend

• Ukwenziwa: 5% HPCTP + 5%-8% aluminiyamu hypophosphite + izinto ezisisiseko zePET.
• Iingenelo: Ukunciphisa iindleko, kunye ne-aluminium hypophosphite enceda ekubambezelekeni komlilo wegesi, okunokunciphisa ukusetyenziswa kwe-HPCTP.
• Qaphela: Ukucaca kufuneka kuvavanywe (i-aluminiyam hypophosphite inokubangela inkungu encinci).

3. Iingcebiso zokucubungula nokuvavanya

• Inkqubo yokuSasaza: Sebenzisa isixhobo sokukhupha umlilo esinezikrufu ezimbini ukuqinisekisa ukusasazeka okufanayo kwezinto ezithintela ilangatye kwaye uphephe ukuhlangana okuphazamisa ukukhanya.
• Uvavanyo lokuBuyiselwa yiLanga: Vavanya ngokwemigangatho ye-UL94 VTM okanye i-Oxygen Index (OI), ujolise kwi-OI > 28%.
• Uvavanyo lokungafihli nto: Linganisa umngxuma usebenzisa imitha yomngxuma, uqinisekise umngxuma < 5% (ubukhulu befilimu: 0.3-1.6 mm).

4. Uthelekiso lweendleko

Itheyibhile yokulayisha engapheliyo kunye nokunyuka kweendleko

5. Isiphelo

• Ukhetho olukhethwayo: I-HPCTP yodwa kwi-8%-10%, ilungelelanisa ukukhanya kunye nokungacimi komlilo.
• Enye indlela: Umxube we-HPCTP kunye ne-aluminium hypophosphite, efuna ukuqinisekiswa kokungafihlisi kunye nemiphumo yokusebenzisana.

Ingcebiso: Umthengi kufuneka enze uvavanyo oluncinci kuqala, egxile ekuthinteleni ilangabi (UL94/OI) kunye novavanyo lwe-haze, aze alungise indlela esetyenziswa ngayo kunye nenkqubo. Ukuba kufuneka kuncitshiswe iindleko ngakumbi, jonga i-aluminium hypophosphite eguqulweyo kumphezulu okanye i-phosphorus-based flame retardants entsha.
