Flame Retardant Solutions for PET Sheet Films

Flame Retardant Solutions for PET Sheet Films

Umukiriya akora firime ya flame-retardant ya PET yerekana amashusho afite umubyimba uri hagati ya 0,3 na mm 1,6, ukoresheje hexaphenoxycyclotriphosphazene (HPCTP) ugashaka kugabanya ibiciro. Hano hepfo harasabwa ibisobanuro hamwe nisesengura rirambuye kuri firime ya flame-retardant ya PET:

1. Isesengura rya Flame Retardant Guhitamo

Hexaphenoxycyclotriphosphazene (HPCTP)

• Ibyiza: Foshazene ishingiye kuri flame retardants ikwirakwiza neza muri PET, ikomeza gukorera mu mucyo mwinshi. Uburyo bwa flame-retardant uburyo bukubiyemo kwishyiriraho icyiciro cya feri hamwe na gaz-fasi ya radical umutego, bigatuma bikwiranye na firime iboneye.
• Igipimo: Basabwe kuri 5% -10%. Umubare urenze urugero urashobora kugira ingaruka kumiterere.
• Igiciro: Ugereranije ni hejuru, ariko igiciro cyose gikomeza gucungwa kumitwaro yo hasi.

Aluminium Hypophosphite

• Ibibi: Ifu ya organic organique irashobora gutera igihu, bigira ingaruka kumucyo. Ingano nini cyane cyangwa ingano yo hejuru irashobora gukenerwa kugirango ikoreshwe.
• Ibisabwa: Ntabwo bisabwa wenyine; irashobora kuvangwa na HPCTP kugirango igabanye igiciro rusange (ikizamini cyo gukorera mu mucyo gisabwa).

2. Basabwe guhitamo

Ihitamo 1: Sisitemu imwe ya HPCTP

• Gutegura: 8% -12% HPCTP + PET ibikoresho fatizo.
• Ibyiza: Gukorera mu mucyo no gukora flame-retardant ikora neza (irashobora kugera kuri UL94 VTM-2 cyangwa VTM-0).
• Ikigereranyo cyibiciro: Kuri 10% yikuramo, kwiyongera kubiciro kuri kg ya PET ni hafi ¥ 10 (¥ 100 / kg × 10%).

Ihitamo 2: HPCTP + Ivanga rya Aluminium Hypophosphite

• Imiterere: 5% HPCTP + 5% -8% aluminium hypophosphite + PET ibikoresho fatizo.
• Ibyiza: Kugabanya ibiciro, hamwe na aluminium hypophosphite ifasha mukugabanya gazi-fase ya flame, bishobora kugabanya imikoreshereze ya HPCTP.
• Icyitonderwa: Gukorera mu mucyo bigomba kugeragezwa (aluminium hypophosphite irashobora gutera igihu gito).

3. Gutunganya no Kugerageza Ibyifuzo

• Uburyo bwo gutatanya: Koresha impanga-ebyiri kugirango ukwirakwize kimwe cya retardants kandi wirinde agglomeration igira ingaruka kumucyo.
• Kwipimisha Flame Retardancy: Suzuma ukurikije ibipimo bya UL94 VTM cyangwa Oxygene (OI), ugamije OI> 28%.
• Kwipimisha mu mucyo: Gupima igihu ukoresheje metero yumucyo, ukareba igihu <5% (uburebure bwa firime: 0,3-1,6 mm).

4. Kugereranya ibiciro

Flame Retardant Loading hamwe nigiciro cyo Kongera Imbonerahamwe

5. Umwanzuro

• Ihitamo ryatoranijwe: HPCTP yonyine kuri 8% -10%, iringaniza gukorera mu mucyo no kutagira umuriro.
• Ubundi buryo: Kuvanga HPCTP na aluminium hypophosphite, bisaba kugenzura neza no gukorera hamwe.

Icyifuzo: Umukiriya agomba kubanza gukora ibigeragezo bito, akibanda ku gucana umuriro (UL94 / OI) no gupima ibicu, hanyuma agahindura uburyo bwo gukora. Niba hakenewe kugabanurwa ibiciro, shakisha hejuru ya aluminium hypophosphite cyangwa fosifore ishingiye kuri flame retardants.
