Gusimbuza sisitemu ya antimoni trioxide/aluminium hydroxide igabanya umuriro na aluminiyumu hypophosphite/zinc borate

Ku cyifuzo cy'umukiriya cyo gusimbuza sisitemu ya antimony trioxide/aluminium hydroxide fire retardant system na aluminiyumu hypophosphite/zinc borate, ibi bikurikira ni gahunda y'ikoranabuhanga ihamye yo gushyira mu bikorwa hamwe n'ingingo z'ingenzi zo kugenzura:

I. Igishushanyo mbonera cya sisitemu yo gukora imiterere ihanitse

1. Icyitegererezo cyo Guhindura Igipimo Gihinduka

• Igipimo cy'ibanze: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Ubusabe bwo Kudakoresha Umuriro Ukabije: AHP 15% + ZB 5% (LOI ishobora kugera kuri 35%)
• Igisubizo gihendutse: AHP 9% + ZB 9% (Gukoresha inyungu ya ZB, bigabanya ikiguzi ho 15%)

1. Ibisubizo byo guhuza Synergist

• Ubwoko bwo Kugabanya Umwotsi: Ongeraho 2% ya zinc molybdate + 1% ya nano-kaolin (ubucucike bw'umwotsi bwagabanutseho 40%)
• Ubwoko bwo Gukomeza: Ongeraho 3% bya boehmite yahinduwe ku buso (imbaraga zo kuzunguruka ziyongereyeho 20%)
• Ubwoko bw'Ikinyabutabire Kirwanya Ihindagurika ry'Ikirere: Ongeraho 1% by'umuti ugabanya ubukana bw'urumuri rwa amine (UV irwanya gusaza inshuro 3)

II. Ingingo z'ingenzi zo kugenzura uburyo bwo gutunganya

1. Amabwiriza yo Kwita ku Bikoresho Bisanzwe

• Hypophosfite ya aluminiyumu: Kumisha ifu ku bushyuhe bwa 120°C mu gihe cy'amasaha 4 (ubushuhe ≤ 0.3%)
• Borate ya Zinc: Kumisha umwuka kuri 80°C mu gihe cy'amasaha 2 (kugira ngo hirindwe kwangirika kw'imiterere ya kristu)

1. Idirishya ryo kuvanga

• Kuvanga by'ibanze: Kuvanga umuvuduko muto (500 rpm) kuri 60°C mu gihe cy'iminota 3 kugira ngo pulasitiki yuzuye yinjire
• Kuvanga kwa kabiri: Kuvanga umuvuduko mwinshi (1500 rpm) kuri 90°C mu gihe cy'iminota 2, ukareba ko ubushyuhe butarenga 110°C
• Kugenzura ubushyuhe bwo gusohora amazi: ≤ 100°C (kugira ngo hirindwe ko AHP ibora imburagihe)

III. Ibipimo ngenderwaho byo kugenzura imikorere

1. Matrix yo Kudashira kw'Umuriro

• Isuzuma rya LOI Gradient: 30%, 32%, 35% by'imiti ijyanye nayo
• Igenzura ry'uruhererekane rwa UL94 rwuzuye: Ingano ya V-0 ku bugari bwa 1.6mm/3.2mm
• Isesengura ry'Ubuziranenge bw'Urutonde rwa Char: Isuzuma rya SEM ry'ubucucike bw'urwego rwa char (cyanengwa ni ≥80μm urwego ruhoraho)

1. Ibisubizo by'Uburyo bwo Kwishyura Imikorere ya Mekaniki

• Guhindura Modulus Irashya: Kuri buri 10% by'izamuka ry'umucanwa ugabanya umuriro, ongeramo 1.5% DOP + 0.5% by'amavuta ya soya yakuwemo umwuka
• Kongera imbaraga z'ingaruka: Ongeraho 2% by'impinduka za ACR ku gikoresho cy'ibanze

IV. Ingamba zo kunoza ibiciro

1. Ibisubizo byo Gusimbuza Ibintu Bisanzwe

• Hypophosfite ya aluminiyumu: Kugeza kuri 30% bishobora gusimburwa na ammonium polyphosphate (igiciro cyagabanijweho 20%, ariko kwirinda amazi bigomba kwitabwaho)
• Borate ya Zinc: Koresha 4.5% ya zinc borate + 1.5% ya barium metaborate (ituma umwotsi ugabanuka)

1. Ingamba zo Kugabanya Ikiguzi mu Mikorere

• Ikoranabuhanga rya Masterbatch: Ibice bigabanya umuriro mbere y'uko utangira gukoreshwa mu buryo bwa masterbatch ku kigero cya 50% (bigabanya ikoreshwa ry'ingufu zo gutunganya umuriro ku kigero cya 30%)
• Gukoresha ibikoresho bishobora kongera gukoreshwa: Emera kongeramo 5% by'ibinyampeke (bisaba kongeramo 0.3% by'ibinyampeke bihamye)

V. Ingamba zo Kugenzura Ingaruka

1. Gukumira kwangirika kw'ibikoresho

• Gukurikirana Viscosity ya Melt mu gihe nyacyo: Gupima imiterere y'amajwi ...
• Uburyo bwo kuburira amabara: Ongeraho 0.01% pH indicator; ibara ridasanzwe rituma habaho gufunga ako kanya

1. Ibisabwa ku kurinda ibikoresho

• Screw ifite Chrome: Irinda kwangirika kwa aside (cyane cyane mu gice cy'umusemburo)
• Sisitemu yo gukuraho ubushuhe: Kubungabunga ibidukikije bitunganywa ku rugero rw'ikinyabutabire ≤ -20°C
