(Idasilẹ lọwọlọwọ: Aluminiomu hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Core Issue Analysis

1. Awọn idiwọn ti Ilana lọwọlọwọ:

• Aluminiomu hypophosphite: Ni akọkọ ṣe idinku itanka ina ṣugbọn o ni idinku eefin to lopin.
• MCA: A gaasi-alakoso iná retardant munadoko fun afterglow (tẹlẹ ipade afojusun) sugbon insufficient fun ijona idinku ẹfin.
• Zinc borate: Ṣe igbega didasilẹ char ṣugbọn ko ni iwọn lilo (2 phr nikan), ti o kuna lati ṣe agbekalẹ awọ ẹwa iwuwo to lati dinku ẹfin.

II. Awọn ilana Imudara

1. Ṣatunṣe Awọn ipin agbekalẹ ti o wa tẹlẹ

• Aluminiomu hypophosphite: Mu si18–20 phr(ṣe imudara idaduro ina-alakoso ti di-alakoso; ṣe atẹle irọrun).
• MCA: Mu si6–8 phr(igbelaruge gaasi-ipele igbese; nmu iye le degrade processing).
• Zinc borate: Mu si3–4 pqr(okun char Ibiyi).

Apeere Titunse Ilana:

• Aluminiomu hypophosphite: 18 phr
• MCA: 7 phr
• Zinc borate: 4 phr

2. Agbekale Ga-ṣiṣe Ẹfin Suppressants

• Molybdenum agbo(fun apẹẹrẹ, zinc molybdate tabi ammonium molybdate):
• Ipa: Catalyzes dida eedu, ṣiṣẹda idena ipon lati dènà ẹfin.
• Iwọn lilo: 2-3 phr (ṣepọ pẹlu borate zinc).
• Nanoclay (montmorillonite):
• Ipa: Ti ara idankan lati din flammable gaasi Tu.
• Iwọn lilo: 3–5 phr (iyipada-dada fun pipinka).
• Silikoni-orisun ina retardants:
• Ipa: Ṣe ilọsiwaju didara ẹwa ati idinku ẹfin.
• Iwọn lilo: 1–2 phr (yago fun pipadanu akoyawo).

3. Amuṣiṣẹpọ System ti o dara ju

• Zinc borateFikun-un 1-2 phr lati muṣiṣẹpọ pẹlu aluminiomu hypophosphite ati zinc borate.
• Ammonium polyphosphate (APP): Ṣafikun 1–2 phr lati mu iṣe ipele gaasi pọ si pẹlu MCA.

III. Niyanju okeerẹ agbekalẹ

Awọn esi ti a reti:

• Idapo ẹfin ijona: ≤200 (nipasẹ char + gaasi amuṣiṣẹpọ alakoso).
• Afterglow èéfín iwuwo: Ṣe itọju ≤200 (MCA + borate zinc).

IV. Awọn akọsilẹ Imudara Ilana bọtini

1. Sise iwọn otutu: Ṣe itọju 180-200 ° C lati ṣe idiwọ idibajẹ ti ina ti o ti tọjọ.
2. Pipin:

• Lo didapọ iyara to gaju (≥2000 rpm) fun pinpin nanoclay/molybdate aṣọ.
• Ṣafikun 0.5–1 phr silane asoju silane (fun apẹẹrẹ, KH550) lati mu imudara kikun kun.

1. Fiimu Ibiyi: Fun simẹnti, din itutu oṣuwọn lati dẹrọ char Layer Ibiyi.

V. Awọn Igbesẹ Afọwọsi

1. Idanwo Laabu: Mura awọn ayẹwo fun apẹrẹ ti a ṣe iṣeduro; ṣe UL94 sisun inaro ati awọn idanwo iwuwo ẹfin (ASTM E662).
2. Iwontunws.funfun Performance: Idanwo agbara fifẹ, elongation, ati akoyawo.
3. Imudara aṣetunṣe: Ti iwuwo ẹfin ba wa ni giga, tun ṣe atunṣe molybdate tabi nanoclay (± 1 phr).

VI. Iye owo & O ṣeeṣe

• Owo Ipa: Zinc molybdate (~¥50/kg) + nanoclay (~¥30/kg) pọ si iye owo lapapọ nipasẹ <15% ni ≤10% ikojọpọ.
• Iwontunwonsi ile-iṣẹ: Ni ibamu pẹlu boṣewa TPU processing; ko si ohun elo pataki ti o nilo.

VII. Ipari

Nipasẹnpo borate zinc + fifi molybdate + nanoclay, eto iṣe-mẹta (eedu Ibiyi + gaasi fomipo + ti ara idankan) le ṣaṣeyọri iwuwo ẹfin ijona ibi-afẹde (≤200). Prioritize igbeyewo awọnmolybdate + nanoclayapapo, lẹhinna awọn iwọn-tunne-itanran fun iwọntunwọnsi iṣẹ ṣiṣe idiyele.
