Isisombululo esicwangcisiweyo sokunciphisa i-TPU yeFilimu yoMsi woMsi

Isisombululo esicwangcisiweyo sokunciphisa i-TPU yeFilimu yoMsi wokuxinwa komsi (Okwangoku: 280; Ithagethi: <200)
(Ukwenziwa kwangoku: I-Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Uhlalutyo lweMiba enguNdoqo

1. Imida yoLwakhiwo lwangoku:

• I-aluminium hypophosphite: Ngokuyintloko icinezela ukusasazeka kwedangatye kodwa icuthe umsi omncinci.
• MCA: Igas-phase flame retardant esebenzayo emva kokuvutha (sele ifikelele ekujoliswe kuyo) kodwa ayonelanga ukunciphisa umsi wokutsha.
• I-zinc borate: Ikhuthaza ukwenziwa kwe char kodwa idosi kancinane (kuphela 2 phr), iyasilela ukwenza intlako exineneyo eyaneleyo yokucinezela umsi.

1. Imfuneko ephambili:

• Nciphisa ukuxinana komsi wokutsha ngokusebenzisaukuthomalalisa umsi owomeleziweyookanyeiindlela zokuhlanjululwa kwesigaba segesi.

II. IziCwangciso zokuSebenza

1. Lungisa uLwayisho olukhoyo olukhoyo

• I-aluminium hypophosphite: Yandisa ku18–20 phr(uphucula ukuncitshiswa komlilo wesigaba esincitshisiweyo; ukujonga ukuguquguquka).
• MCA: Yandisa ku6–8 phr(yonyusa intshukumo yesigaba segesi; izixa ezigqithisileyo zinokuthoba umgangatho wokuqhuba).
• I-zinc borate: Yandisa ku3–4 phr(yomeleza ukwakheka kwe char).

Uyilo oluLungisiweyo loMzekelo:

• I-aluminium hypophosphite: 18 phr
• MCA: 7 phr
• I-zinc borate: 4 phr

2. Yazisa iziXhobo zoMsi eziSebenza ngokuPhezulu

• Iikhompawundi zeMolybdenum(umzekelo, i-zinc molybdate okanye i-ammonium molybdate):
• Indima: Yenza ukwakheka kwe char, kudala umqobo oshinyeneyo ukuvala umsi.
• Umthamo: 2-3 phr (idibanisa ne-zinc borate).
• Nanoclay (montmorillonite):
• Indima: Isithintelo somzimba sokunciphisa ukukhutshwa kwegesi enokutsha.
• Umthamo: 3–5 phr (umphezulu-uguqulelwe ukusasazwa).
• I-silicone-based retardants yomlilo:
• Indima: Iphucula umgangatho we-char kunye nokunciphisa umsi.
• Umthamo: 1-2 phr (ugwema ilahleko elubala).

3. I-Synergistic System Optimization

• I-zinc borate: Yongeza i-1–2 phr ukudibanisa ne-aluminium hypophosphite kunye ne-zinc borate.
• I-Ammonium polyphosphate (APP): Yongeza i-1–2 phr ukwandisa isenzo sesigaba segesi kunye ne-MCA.

III. Uqulunqo oluBanzi oluCetyisiweyo

Iziphumo ezilindelekileyo:

• Uxinzelelo lomsi wokutsha: ≤200 (nge-char + i-gas-phase synergy).
• Ukuxinana komsi emva kokuvutha: Gcina i-≤200 (MCA + zinc borate).

IV. Amanqaku oPhuculo lweNkqubo engundoqo

1. Ukuqhuba Ubushushu: Gcina i-180-200 ° C ukuthintela ukubola kwangaphambi kwexesha lomlilo.
2. Ukusasazwa:

• Sebenzisa ukuxuba ngesantya esiphezulu (≥2000 rpm) kwi-nanoclay efanayo / ukusabalalisa kwe-molybdate.
• Yongeza i-0.5-1 phr i-agent yokudibanisa i-silane (umzekelo, i-KH550) ukuphucula ukuhambelana kokuzalisa.

1. Ukwenziwa kweFilimu: Ukuphosa, nciphisa izinga lokupholisa ukuququzelela ukwakheka kwe-char layer.

V. Amanyathelo okuqinisekisa

1. Uvavanyo lwaseLab: Lungisa iisampulu ngokuqulunqwa okucetyiswayo; ukuqhuba i-UL94 ukutshisa ngokuthe nkqo kunye neemvavanyo zokuxinana komsi (ASTM E662).
2. Ulungelelwaniso lokuSebenza: Vavanya amandla okuqina, ubude, kunye nokungafihli.
3. UPhuculo oluphinda-phindayo: Ukuba ukuxinana komsi kuhlala kuphezulu, lungisa ngokuthe kratya i-molybdate okanye i-nanoclay (± 1 phr).

VI. Iindleko & Nokwenzeka

• Iindleko zeMpembelelo: I-Zinc molybdate (~ ¥50 / kg) + i-nanoclay (~ ¥30 / kg) yandisa iindleko ezipheleleyo nge-<15% kwi-≤10% yokulayisha.
• I-Industrial Scalability: Iyahambelana nenkqubo ye-TPU eqhelekileyo; akukho zixhobo zikhethekileyo zifunekayo.

VII. Ukuqukumbela

Nguukwandisa i-zinc borate + ukongeza i-molybdate + nanoclay, inkqubo yesenzo esiphindwe kathathu (ukubunjwa kwe-char + dilution yegesi + umqobo womzimba) unokufezekisa ubuninzi bomsi ojoliswe kuwo (≤200). Ukubeka phambili uvavanyo lwemolybdate + nanoclayindibaniselwano, emva koko i-fine-tune ratios ye-cost-performance balance.
