Ukufaka esikhundleni sesistimu ye-antimony trioxide/aluminium hydroxide flame retardant nge-aluminium hypophosphite/zinc borate

Ngesicelo sekhasimende sokufaka esikhundleni sesistimu ye-antimony trioxide/aluminium hydroxide flame retardant nge-aluminium hypophosphite/zinc borate, okulandelayo uhlelo lokusebenzisa ubuchwepheshe oluhlelekile kanye namaphuzu okulawula abalulekile:

I. Umklamo Wesistimu Yokwakheka Okuthuthukisiwe

1. Imodeli Yokulungiswa Kwesilinganiso Esiguquguqukayo

• Isilinganiso Esiyisisekelo: I-aluminium hypophosphite (AHP) 12% + i-Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Isidingo Sokuvinjelwa Kokushisa Okuphezulu: AHP 15% + ZB 5% (i-LOI ingafinyelela ku-35%)
• Isixazululo Esingabizi Kakhulu: AHP 9% + ZB 9% (Ukusebenzisa inzuzo yezindleko ze-ZB, kunciphisa izindleko ngo-15%)

1. Izixazululo Zokuhlanganiswa Kwe-Synergist

• Uhlobo Lokucindezela Intuthu: Engeza i-2% ye-zinc molybdate + 1% ye-nano-kaolin (ubuningi bentuthu buncishiswe ngo-40%)
• Uhlobo Lokuqinisa: Engeza i-boehmite eguquliwe ebusweni engu-3% (amandla okugoba akhuliswe ngo-20%)
• Uhlobo Olumelana Nesimo Sezulu: Engeza i-1% ye-hindled amine light stabilizer (ukumelana nokuguga kwe-UV kwandiswe kathathu)

II. Amaphuzu Okulawula Ukucubungula Okubalulekile

1. Amazinga Okwelapha Izinto Ezingavuthiwe

• I-Aluminium Hypophosphite: Ukomisa nge-vacuum ku-120°C amahora ama-4 (umswakama ≤ 0.3%)
• I-Zinc Borate: Ukomisa komoya ku-80°C amahora ama-2 (ukuvimbela umonakalo wesakhiwo sekristalu)

1. Iwindi Lenqubo Yokuxuba

• Ukuxuba Okuyinhloko: Ukuxuba ngesivinini esiphansi (500 rpm) ku-60°C imizuzu emi-3 ukuqinisekisa ukungena kwe-plasticizer egcwele
• Ukuxuba Kwesibili: Ukuxuba ngesivinini esiphezulu (1500 rpm) ku-90°C imizuzu emi-2, ukuqinisekisa ukuthi izinga lokushisa alidluli ku-110°C
• Ukulawula Izinga Lokushisa Lokukhipha Igesi: ≤ 100°C (ukuvimbela ukubola kwe-AHP ngaphambi kwesikhathi)

III. Izindinganiso Zokuqinisekisa Ukusebenza

1. I-Flame Retardancy Matrix

• Ukuhlolwa kwe-LOI Gradient: 30%, 32%, 35% amafomula ahambisanayo
• Ukuqinisekiswa Kochungechunge Olugcwele lwe-UL94: Isilinganiso se-V-0 kubukhulu obungu-1.6mm/3.2mm
• Ukuhlaziywa Kwekhwalithi Yesilayidi Se-Char: Ukuqashelwa kwe-SEM kobuningi besendlalelo se-char (kunconywa isendlalelo esiqhubekayo esingu-≥80μm)

1. Izixazululo Zokunxephezela Ukusebenza Kwemishini

• Ukulungiswa kweModulus Enwebekayo: Ngokwanda ngakunye okungu-10% kwe-flame retardant, engeza i-1.5% DOP + 0.5% uwoyela wesoya ofakwe i-epoxidized
• Ukuthuthukiswa Kwamandla Omthelela: Engeza i-2% core-shell ACR impact modifier

IV. Amasu Okuthuthukisa Izindleko

1. Izixazululo Zokufaka Izinto Ezingavuthiwe

• I-Aluminium Hypophosphite: Kufika ku-30% ongashintshwa nge-ammonium polyphosphate (izindleko zincishiswe ngo-20%, kodwa ukumelana namanzi kumele kucatshangelwe)
• I-Zinc Borate: Sebenzisa i-4.5% zinc borate + 1.5% barium metaborate (ithuthukisa ukucindezela intuthu)

1. Izindlela Zokunciphisa Izindleko Zenqubo

• Ubuchwepheshe be-Masterbatch: Izithibi zomlilo ezihlanganisiwe zibe yi-masterbatch yokuhlushwa engu-50% (kunciphisa ukusetshenziswa kwamandla okucubungula ngo-30%)
• Ukusetshenziswa Kwezinto Ezisetshenziswe Kabusha: Vumela ukwengeza okungu-5% kokugaya kabusha (kudinga ukuphinda kugcwaliswe okungu-0.3% kokuqinisa)

V. Izinyathelo Zokulawula Ingozi

1. Ukuvimbela Ukuwohloka Kwezinto Ezibonakalayo

• Ukuqapha Ukuthambekela Kokuncibilika Kwe-Melt Kwesikhathi Sangempela: Ukuhlolwa kwe-torque rheometer, ukushintshashintsha kwe-torque kufanele kube ngaphansi kuka-5%
• Indlela Yokuxwayisa Ngombala: Engeza inkomba ye-pH engu-0.01%; ukushintsha kombala okungavamile kubangela ukuvala ngokushesha

1. Izidingo Zokuvikela Imishini

• Isikulufu Esifakwe I-Chrome: Kuvimbela ukugqwala kwe-asidi (ikakhulukazi esigabeni sokufa)
• Uhlelo Lokususa Umswakama: Gcina indawo yokucubungula isezingeni lamazolo ≤ -20°C
