Kusintha dongosolo la antimony trioxide/aluminum hydroxide lawi loletsa moto ndi aluminium hypophosphite/zinc borate

Pa pempho la kasitomala loti asinthe dongosolo la antimony trioxide/aluminum hydroxide flame retardant ndi aluminium hypophosphite/zinc borate, izi ndi ndondomeko yoyendetsera bwino ukadaulo ndi mfundo zazikulu zowongolera:

I. Kapangidwe ka Makina Opangira Zinthu Mwapamwamba

1. Chitsanzo Chosinthira Chiŵerengero Cha Mphamvu

• Chiŵerengero cha Maziko: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Kufunika Kwambiri kwa Kubweza Moto: AHP 15% + ZB 5% (LOI ikhoza kufika 35%)
• Yankho Lotsika Mtengo: AHP 9% + ZB 9% (Kugwiritsa ntchito phindu la mtengo wa ZB, kumachepetsa mtengo ndi 15%)

1. Mayankho Ophatikizana a Synergist

• Mtundu Woletsa Utsi: Onjezani 2% zinc molybdate + 1% nano-kaolin (kuchuluka kwa utsi kumachepetsedwa ndi 40%)
• Mtundu Wolimbitsa: Onjezani 3% ya boehmite yosinthidwa pamwamba (mphamvu yopindika yawonjezeka ndi 20%)
• Mtundu Wosagonja ku Nyengo: Onjezani 1% yoletsa kuwala kwa amine (kukana kukalamba kwa UV kumakulitsidwa ndi katatu)

II. Mfundo Zofunikira Zowongolera Kukonza

1. Miyezo Yopangira Zinthu Zo ...

• Aluminiyamu HypophosphiteKuumitsa kwa vacuum pa 120°C kwa maola 4 (chinyezi ≤ 0.3%)
• Zinc BorateKuumitsa kwa mpweya pa 80°C kwa maola awiri (kuti mupewe kuwonongeka kwa kapangidwe ka kristalo)

1. Zenera Losakaniza Njira

• Kusakaniza KoyambaKusakaniza kothamanga pang'ono (500 rpm) pa 60°C kwa mphindi zitatu kuti pulasitiki ilowe bwino
• Kusakaniza KwachiwiriKusakaniza mwachangu (1500 rpm) pa 90°C kwa mphindi ziwiri, kuonetsetsa kuti kutentha sikupitirira 110°C
• Kulamulira Kutentha kwa Magazi: ≤ 100°C (kupewa kuwonongeka kwa AHP msanga)

III. Miyezo Yotsimikizira Magwiridwe Antchito

1. Matrix ya Kubwerera kwa Moto

• Kuyesa kwa LOI Gradient: 30%, 32%, 35% mankhwala ofanana
• Kutsimikizira kwa UL94 Full-Series: V-0 mlingo pa makulidwe a 1.6mm/3.2mm
• Kusanthula kwa Ubwino wa Char Layer: Kuwona kwa SEM kwa kuchuluka kwa zigawo za char (koyenera kuti ≥80μm wosanjikiza wopitilira)

1. Mayankho Othandizira Kulipira Magwiridwe Antchito a Makina

• Kusintha kwa Elastic Modulus: Pa kuwonjezeka kulikonse kwa 10% kwa choletsa moto, onjezerani 1.5% DOP + 0.5% ya mafuta a soya osungunuka.
• Kupititsa patsogolo Mphamvu ya Mphamvu: Onjezani 2% core-shell ACR impact modifier

IV. Njira Zokonzera Mtengo

1. Mayankho Osinthira Zinthu Zopangira

• Aluminiyamu Hypophosphite: Mpaka 30% yomwe ingasinthidwe ndi ammonium polyphosphate (mtengo wake wachepetsedwa ndi 20%, koma kukana madzi kuyenera kuganiziridwa)
• Zinc BorateGwiritsani ntchito 4.5% zinc borate + 1.5% barium metaborate (imathandiza kuchepetsa utsi)

1. Njira Zochepetsera Mtengo

• Ukadaulo wa Masterbatch: Zoletsa moto zomwe zingagwiritsidwe ntchito popanga masterbatch ya 50% (zimachepetsa kugwiritsa ntchito mphamvu ndi 30%).
• Kugwiritsa Ntchito Zinthu Zobwezerezedwanso: Lolani 5% iwonjezeredwenso (imafuna kubwezeretsanso 0.3% stabilizer)

V. Njira Zowongolera Zoopsa

1. Kupewa Kuwonongeka kwa Zinthu

• Kuwunika Kukhuthala kwa Kusungunuka kwa Nthawi Yeniyeni: Kuyesa kwa torque rheometer, kusinthasintha kwa torque kuyenera kukhala <5%
• Njira Yochenjeza Mitundu: Onjezani chizindikiro cha pH cha 0.01%; kusintha kwa mtundu kosazolowereka kumayambitsa kutseka nthawi yomweyo

1. Zofunikira pa Chitetezo cha Zipangizo

• Chokulungira Chokhala ndi Chrome: Zimaletsa dzimbiri la asidi (makamaka m'gawo la die)
• Dongosolo Lochotsa ChinyeziSungani malo ogwirira ntchito ngati mame ≤ -20°C
