Ukutshintsha inkqubo ye-antimony trioxide/aluminum hydroxide flame retardant nge-aluminium hypophosphite/zinc borate

Kwisicelo somthengi sokutshintsha inkqubo ye-antimony trioxide/aluminum hydroxide flame retardant nge-aluminium hypophosphite/zinc borate, oku kulandelayo sisicwangciso sokusetyenziswa kobugcisa esicwangcisiweyo kunye neendawo zolawulo eziphambili:

I. Uyilo lweNkqubo yoBuchule obuPhambili

1. Imodeli yoLungiso lweDynamic Ratio

• Ireyithingi yeSiseko: I-Aluminium hypophosphite (AHP) 12% + I-Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Imfuno yokuBuyiselwa kweLanga eliPhezulu: AHP 15% + ZB 5% (i-LOI ingafikelela kwi-35%)
• Isisombululo Esixabiso Liphantsi: AHP 9% + ZB 9% (Ukusebenzisa inzuzo yeendleko zeZB, kunciphisa iindleko nge-15%)

1. Izisombululo zoMdibaniso weSynergist

• Uhlobo lokuCima umsi: Yongeza i-2% ye-zinc molybdate + 1% ye-nano-kaolin (ubuninzi bomsi buncitshiswe ngama-40%)
• Uhlobo loQinisekiso: Yongeza i-3% ye-boehmite eguqulweyo kumphezulu (amandla okugoba anyuswe ngama-20%)
• Uhlobo Olumelana Nemozulu: Yongeza i-1% ye-hindled amine light stabilizer (ukumelana nokuguga kwe-UV kwandiswe kathathu)

II. Amanqaku Olawulo Lokucubungula Okubalulekileyo

1. Imigangatho Yonyango Lwangaphambi Kokwenziwa Kwezinto Eziluhlaza

• I-Aluminium Hypophosphite: Ukomisa nge-vacuum kwi-120°C kangangeeyure ezi-4 (ukufuma ≤ 0.3%)
• I-Zinc Borate: Ukomisa komoya kwi-80°C kangangeeyure ezi-2 (ukuthintela umonakalo kwisakhiwo sekristale)

1. Ifestile yeNkqubo yokuxuba

• Ukuxuba okuPhambili: Ukuxuba ngesantya esiphantsi (500 rpm) kwi-60°C imizuzu emi-3 ukuqinisekisa ukungena kweplastiki ngokupheleleyo
• Ukuxuba okwesibini: Ukuxuba ngesantya esiphezulu (1500 rpm) kwi-90°C kangangemizuzu emi-2, ukuqinisekisa ukuba ubushushu abudluli kwi-110°C
• Ulawulo lobushushu bokukhupha: ≤ 100°C (ukuthintela ukubola kwe-AHP ngaphambi kwexesha)

III. Imigangatho yoQinisekiso lokuSebenza

1. I-Flame Retardancy Matrix

• Uvavanyo lweGradient ye-LOI: 30%, 32%, 35% yeefomyula ezihambelanayo
• Ukuqinisekiswa kochungechunge olupheleleyo lwe-UL94: Uvavanyo lwe-V-0 kubukhulu be-1.6mm/3.2mm
• Uhlalutyo loMgangatho weChar Layer: Ukuqwalaselwa kwe-SEM kobuninzi beleyara ye-char (kucetyiswa ukuba kubekho ileyara eqhubekayo eyi-≥80μm)

1. Izisombululo zeMbuyekezo yoMsebenzi woMatshini

• Uhlengahlengiso lweModulus ye-Elastic: Xa unyuka nge-10% ye-10% ye-flame retardant, yongeza i-1.5% DOP + 0.5% ye-epoxidized soy oil
• Ukuphuculwa kwamandla empembelelo: Yongeza i-2% ye-core-shell ACR impact modifier

IV. Amaqhinga okuphucula iindleko

1. Izisombululo zokutshintsha izinto eziluhlaza

• I-Aluminium Hypophosphite: Ukuya kuthi ga kwi-30% enokutshintshwa nge-ammonium polyphosphate (ixabiso lincitshiswe ngama-20%, kodwa ukumelana namanzi kufuneka kuqwalaselwe)
• I-Zinc BorateSebenzisa i-4.5% ye-zinc borate + i-1.5% ye-barium metaborate (iphucula ukuthintela umsi)

1. Amanyathelo okunciphisa iindleko zeNkqubo

• Ubuchwepheshe beMasterbatch: Izithinteli zomlilo ezihlanganisiweyo ngaphambi kokuba zibe yi-50% ye-masterbatch yoxinzelelo (kunciphisa ukusetyenziswa kwamandla okucubungula nge-30%)
• Ukusetyenziswa kwezinto ezisetyenzisiweyo: Vumela ukongeza i-5% yokugaya kwakhona (ifuna ukuphinda kuzaliseke i-0.3% yokuqinisa)

V. Amanyathelo oLawulo loMngcipheko

1. Ukuthintela ukubola kwezinto

• Ukubeka iliso kwi-Melt Viscosity ngexesha langempelaUvavanyo lwe-torque rheometer, ukuguquguquka kwe-torque kufuneka kube <5%
• Indlela Yokulumkisa Ngombala: Yongeza isalathisi se-pH esingu-0.01%; ukutshintsha kombala okungaqhelekanga kubangela ukuvala ngokukhawuleza

1. Iimfuneko zoKhuseleko lweZixhobo

• Isikrufu esine-Chrome-Plated: Ithintela ukubola kwe-asidi (ingakumbi kwicandelo lokufa)
• Inkqubo yokususa ubumanzi: Gcina indawo yokucubungula inqanaba lombethe ≤ -20°C
