Ngesicelo sekhasimende sokushintsha isistimu ye-antimony trioxide/aluminium hydroxide flame retardant nge-aluminium hypophosphite/zinc borate, okulandelayo wuhlelo lokuqalisa lobuchwepheshe oluhlelekile kanye namaphuzu okulawula abalulekile:
I. Idizayini Yesistimu Yokwenza Okuthuthukile
- Imodeli Yokulungisa Isilinganiso Esinamandla
- Isilinganiso sesisekelo: I-Aluminium hypophosphite (AHP) 12% + I-Zinc borate (ZB) 6% (P:B isilinganiso se-molar 1.2:1)
- Isidingo Esiphezulu Sokubuyiswa Kwelangabi: AHP 15% + ZB 5% (LOI ingafinyelela ku-35%)
- Isixazululo Esinezindleko Eziphansi: AHP 9% + ZB 9% (Ukusebenzisa inzuzo yezindleko ze-ZB, kunciphisa izindleko ngo-15%)
- I-Synergist Combination Solutions
- Uhlobo Lokucisha Intuthu: Engeza u-2% we-zinc molybdate + 1% nano-kaolin (ukuminyana kwentuthu kuncishiswe ngo-40%)
- Uhlobo Lokuqiniswa: Engeza i-3% ye-boehmite eguquliwe phezulu (amandla e-flexural anda ngo-20%)
- Uhlobo Olumelana Nesimo Sezulu: Engeza u-1% ovinjelwe ukukhanya kwe-amine (ukumelana nokuguga kwe-UV kunwetshwe ngo-3x)
II. Amaphuzu Okulawula Ukucubungula Okubalulekile
- I-Raw Material Pretreatment Standards
- I-Aluminium Hypophosphite: I-vacuum drying ku-120°C amahora angu-4 (umswakama ≤ 0.3%)
- I-Zinc Borate: Ukomisa ukugeleza komoya ku-80°C amahora angu-2 (ukuvikela ukulimala kwesakhiwo sekristalu)
- Iwindi Lenqubo Yokuxuba
- Ukuxuba Okuyinhloko: Ukuxuba okunejubane eliphansi (500 rpm) ku-60°C imizuzu emi-3 ukuqinisekisa ukungena okugcwele kwe-plasticizer
- Ukuxuba Kwesibili: Ukuxubana kwejubane eliphezulu (1500 rpm) ku-90°C imizuzu emi-2, ukuqinisekisa ukuthi izinga lokushisa alidluli ku-110°C
- I-Discharge Temperature Control: ≤ 100°C (ukuvimbela ukubola kwe-AHP ngaphambi kwesikhathi)
III. Amazinga Okuqinisekisa Ukusebenza
- I-Flame Retardancy Matrix
- Ukuhlolwa kwe-LOI Gradient: 30%, 32%, 35% ukwakheka okuhambisanayo
- Ukuqinisekiswa Kochungechunge Olugcwele lwe-UL94: Isilinganiso se-V-0 ku-1.6mm/3.2mm ukujiya
- Ukuhlaziywa Kwekhwalithi Yesendlalelo Soshar: Ukubhekwa kwe-SEM kokuminyana kwesendlalelo se-char (kunconyiwe ≥80μm isendlalelo esiqhubekayo)
- Izixazululo Zesinxephezelo Sokusebenza Komshini
- Ukulungiswa kwe-Elastic Modulus: Kukho konke ukukhuphuka okungu-10% kokubuyiswa komlilo, engeza u-1.5% DOP + 0.5% uwoyela wesoya epoxidized
- Ukuthuthukisa Amandla Okunomthelela: Engeza isilungisi se-ACR se-core-shell esingu-2%.
IV. Amasu Okuthuthukisa Izindleko
- Izixazululo Zokushintshwa Kwezinto Ezingavuthiwe
- I-Aluminium Hypophosphite: Kufikela ku-30% okungashintshwa nge-ammonium polyphosphate (izindleko zehliswe ngo-20%, kodwa ukumelana namanzi kufanele kubhekwe)
- I-Zinc Borate: Sebenzisa i-4.5% ye-zinc borate + 1.5% ye-barium metaborate (ithuthukisa ukucindezelwa kwentuthu)
- Izinqubo Zokunciphisa Izindleko
- I-Masterbatch Technology: Ama-pre-compound flame retardants abe yi-concentration masterbatch engu-50% (yehlisa ukusetshenziswa kwamandla ngo-30%)
- Ukusetshenziswa Kabusha Kwezinto Ezisetshenziswayo: Vumela ukungezwa kwe-regrind okungu-5% (kudinga ukugcwaliswa kwe-stabilizer engu-0.3%)
V. Izinyathelo Zokulawula Ubungozi
- Ukuvimbela Ukuwohloka Kwezinto
- I-Real-Time Melt Viscosity Monitoring: Ukuhlolwa kwe-torque rheometer, ukushintshashintsha kwe-torque kufanele kube <5%
- Umbala Wesexwayiso Mechanism: Engeza inkomba ye-pH engu-0.01%; ukushintsha kombala okungavamile kubangela ukuvala shaqa ngokushesha
- Izidingo Zokuvikela Izinsiza
- I-Chrome-Plated Screw: Ivimbela ukugqwala kwe-asidi (ikakhulukazi esigabeni sokufa)
- Isistimu Yokunciphisa Umswakama: Gcina indawo yokucubungula indawo yamazolo ≤ -20°C
Isikhathi sokuthumela: Apr-22-2025
