Maka arịrịọ onye ahịa ka ọ dochie antimony trioxide/aluminium hydroxide flame retardant system na aluminom hypophosphite/zinc borate, ihe na-esonụ bụ atụmatụ mmejuputa teknụzụ usoro na isi ihe njikwa:

I. Advanced Formulation System Design

Ihe Nlereanya Mmezi Ratio Dike

Isi Ratio: Aluminom hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P: B molar ratio 1.2:1)
Ọchịchọ nkwụghachi ọkụ dị elu: AHP 15% + ZB 5% (LOI nwere ike iru 35%)
Ngwọta dị ọnụ ala: AHP 9% + ZB 9% (Ịkwalite uru ọnụ ahịa ZB, na-ebelata ọnụ ahịa site na 15%)

Ngwọta Ngwakọta Synergist

Ụdị nkwụsị anwụrụ ọkụ: Tinye 2% zinc molybdate + 1% nano-kaolin (njupụta anwụrụ ọkụ belatara site na 40%)
Ụdị nkwado: Tinye 3% elu-gbanwetụrụ boehmite (ike mgbanwe na-abawanye site na 20%)
Ụdị na-eguzogide ihu igwe: Tinye 1% mgbochi amine ìhè stabilizer (UV ịka nká na-agbatị site na 3x)

II. Isi ihe njikwa nhazi

Ụkpụrụ Ngwọta Ngwa Ngwa

Aluminom hypophosphite: ihicha oghere na 120 ° C maka 4h (mmiri ≤ 0.3%)
Zinc borate: Ikuku ikuku na 80 Celsius C maka 2h (iji gbochie mmebi ihe owuwu kristal)

Window Usoro Ngwakọta

Ngwakọta nke iziziNgwakọta ọsọ dị ala (500 rpm) na 60 ° C maka 3min iji hụ na ntinye plasticizer zuru ezu.
Ngwakọta nke abụọNgwakọta ọsọ dị elu (1500 rpm) na 90 ° C maka 2min, na-ahụ na okpomọkụ anaghị agafe 110 ° C
Njikwa okpomoku mgbapu: ≤ 100°C (iji gbochie ire ere AHP akaghi aka)

III. Ụkpụrụ nkwenye arụmọrụ

Matrix retardancy ọkụ

Nnwale gradient LOI: 30%, 32%, 35% kwekọrọ ekwekọ
Nyocha usoro UL94 zuru oke: V-0 na ọkpụrụkpụ 1.6mm/3.2mm
Nyocha ogo Char Layer: Nleba anya SEM nke njupụta char oyibo (a na-atụ aro ≥80μm oyi akwa na-aga n'ihu)

Ngwọta nkwụghachi ụgwọ arụrụ arụ ọrụ

Ndozi Modulus Elastic: Maka 10% ọ bụla na-abawanye na ire ọkụ, tinye 1.5% DOP + 0.5% mmanụ soybean.
Nkwalite ike mmetụta: Tinye 2% isi-shell ACR mmetụta mgbanwe

IV. Atụmatụ nkwalite ọnụ ahịa

Ngwọta Ndozi Ngwa Ngwa

Aluminom hypophosphiteIhe ruru 30% nke ammonium polyphosphate nwere ike dochie ya (ọnụahịa belatara 20%, mana a ga-atụle nguzogide mmiri)
Zinc borate: Jiri 4.5% zinc borate + 1.5% barium metaborate (na-akwalite nkwụsị anwụrụ ọkụ)

Usoro Mbelata Mbelata Ọnụ ahịa

Teknụzụ Masterbatch: Ndị na-ere ọkụ na-ebu ụzọ gbakọta n'ime 50% itinye uche masterbatch (na-ebelata nhazi ike oriri site na 30%)
Iji ihe eji emegharịgharị: Kwe ka 5% regrind mgbakwunye (chọrọ 0.3% stabilizer replenishzer)

V. Usoro njikwa ihe egwu

Mgbochi mmebi ihe
