Gusimbuza antimoni trioxide / aluminium hydroxide flame retardant sisitemu na aluminium hypophosphite / zinc borate

Kubisaba umukiriya gusimbuza antimoni trioxide / aluminium hydroxide flame retardant sisitemu na aluminium hypophosphite / zinc borate, ibikurikira ni gahunda yo gushyira mubikorwa tekiniki ya sisitemu hamwe ningingo zingenzi zo kugenzura:

I. Igishushanyo mbonera cya sisitemu yo hejuru

1. Ikigereranyo cyimikorere yo Guhindura Icyitegererezo

• Ikigereranyo fatizo: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P: B igipimo cya molar 1.2: 1)
• Icyifuzo cyo Kurinda Umuriro mwinshi: AHP 15% + ZB 5% (LOI irashobora kugera kuri 35%)
• Igisubizo gito: AHP 9% + ZB 9% (Gukoresha inyungu za ZB, kugabanya ibiciro 15%)

1. Gukomatanya Ibisubizo

• Ubwoko bwo Kurwanya Umwotsi: Ongeramo 2% zinc molybdate + 1% nano-kaolin (ubucucike bwumwotsi bwagabanutseho 40%)
• Ubwoko bwo gushimangira: Ongeraho 3% yubuso bwahinduwe boehmite (imbaraga za flexural ziyongereyeho 20%)
• Ubwoko bw'Ibihe: Ongeramo 1% ibangamira urumuri amine (UV gusaza irwanya 3x)

II. Ingingo z'ingenzi zo gutunganya

1. Ibipimo fatizo byo kubanziriza ibikoresho

• Aluminium Hypophosphite: Kuma Vacuum kuri 120 ° C kuri 4h (ubuhehere ≤ 0.3%)
• Zinc Borate: Kuma umwuka wumuyaga kuri 80 ° C kuri 2h (kugirango wirinde kwangirika kwimiterere)

1. Kuvanga inzira Idirishya

• Kuvanga Ibanze: Kuvanga umuvuduko muke (500 rpm) kuri 60 ° C kuri 3min kugirango plastike yuzuye
• Kuvanga kabiri: Kuvanga umuvuduko mwinshi (1500 rpm) kuri 90 ° C kuri 2min, kureba ko ubushyuhe butarenga 110 ° C.
• Gusohora Ubushyuhe: ≤ 100 ° C (kugirango wirinde kwangirika kwa AHP imburagihe)

III. Ibipimo byo kugenzura imikorere

1. Matrix Retardancy Matrix

• Ikizamini cya LOI: 30%, 32%, 35% byateganijwe
• UL94 Igenzura ryuzuye: V-0 igipimo cya 1,6mm / 3.2mm z'ubugari
• Isesengura ryiza rya Char: SEM kwitegereza ubwinshi bwa char layer (bisabwa ≥80μm ikomeza)

1. Imikorere yimikorere yindishyi

• Guhindura Modulus: Kuri buri 10% kwiyongera kwa flame retardant, ongeramo 1.5% DOP + 0.5% amavuta ya soya ya epoxisize
• Ingaruka zo Kongera imbaraga: Ongeraho 2% yibanze-shell ACR impinduka

IV. Ingamba zo Gukwirakwiza Ibiciro

1. Ibisubizo byo gusimbuza ibikoresho

• Aluminium Hypophosphite: Kugera kuri 30% byasimburwa na amonium polyphosifate (igiciro cyagabanutseho 20%, ariko hagomba gutekerezwa kurwanya amazi)
• Zinc Borate: Koresha 4.5% zinc borate + 1.5% barium metaborate (itezimbere guhagarika umwotsi)

1. Inzira Igiciro-Kugabanya Ingamba

• Ikoranabuhanga rya Masterbatch: Imbere ya compound flame retardants muri 50% yibanze (kugabanya ingufu zitunganya 30%)
• Gukoresha Ibikoresho Byakoreshejwe: Emerera 5% kongeraho (bisaba 0.3% kuzuza stabilisateur)

V. Ingamba zo kugenzura ingaruka

1. Kwirinda Ibikoresho

• Kugenzura-Igihe-Gushonga Viscosity Gukurikirana: Torque rheometero yipimisha, ihindagurika rya torque rigomba kuba <5%
• Uburyo bwo Kuburira Ibara: Ongeraho 0,01% igipimo cya pH; ibara ridasanzwe ritera guhagarika ako kanya

1. Ibisabwa Kurinda Ibikoresho

• Imashini ya Chrome: Irinda kwangirika kwa aside (cyane cyane mu gice cyo gupfa)
• Sisitemu yo Kwangiza: Komeza ibidukikije bitunganya ikime ≤ -20 ° C.
