Yuav hloov lub antimony trioxide/aluminum hydroxide flame retardant system nrog aluminium hypophosphite/zinc borate.

Rau cov neeg siv khoom qhov kev thov kom hloov lub antimony trioxide / aluminium hydroxide flame retardant system nrog aluminium hypophosphite / zinc borate, cov hauv qab no yog cov phiaj xwm kev siv tshuab thiab cov ntsiab lus tseem ceeb tswj hwm:

I. Kev Tsim Qauv Txheej Txheem Qib Siab

1. Qauv Kev Kho Kom Zoo Dua Dynamic Ratio

• Qhov Piv Txwv: Aluminium hypophosphite (AHP) 12% + Zinc borate (ZB) 6% (P:B molar ratio 1.2:1)
• Kev Xav Tau Hluav Taws Kub Siab: AHP 15% + ZB 5% (LOI tuaj yeem ncav cuag 35%)
• Kev daws teeb meem pheej yig: AHP 9% + ZB 9% (Siv ZB txoj kev zoo dua, txo tus nqi los ntawm 15%)

1. Kev daws teeb meem sib xyaw ua ke ntawm Synergist

• Hom Kev Tswj Pa Luam YeebNtxiv 2% zinc molybdate + 1% nano-kaolin (cov pa luam yeeb tsawg dua 40%)
• Hom Kev Txhawb NqaNtxiv 3% boehmite uas hloov kho qhov chaw (lub zog khoov tau nce ntxiv 20%)
• Hom Tiv Thaiv Huab CuaNtxiv 1% hindered amine light stabilizer (UV aging resistance txuas ntxiv los ntawm 3x)

II. Cov Ntsiab Lus Tswj Xyuas Kev Ua Haujlwm Tseem Ceeb

1. Cov Qauv Ua Ntej Raw Khoom Siv

• Aluminium Hypophosphite: Siv lub tshuab nqus tsev kom qhuav ntawm 120°C rau 4 teev (dej noo ≤ 0.3%)
• Zinc BorateCua tshuab kom qhuav ntawm 80°C rau 2 teev (kom tiv thaiv kev puas tsuaj rau cov qauv siv lead ua)

1. Qhov Rai Txheej Txheem Sib Tov

• Kev Sib Tov Thawj ZaugKev sib tov qeeb qeeb (500 rpm) ntawm 60 ° C rau 3 feeb kom ntseeg tau tias cov khoom yas nkag mus rau hauv tag nrho
• Kev Sib Tov Thib ObKev sib tov ceev ceev (1500 rpm) ntawm 90 ° C rau 2 feeb, xyuas kom meej tias qhov kub tsis tshaj 110 ° C
• Kev Tswj Kub thiab Txias: ≤ 100 ° C (kom tiv thaiv kev lwj ua ntej lub sijhawm AHP)

III. Cov Qauv Txheeb Xyuas Kev Ua Haujlwm

1. Hluav Taws Kub Retardancy Matrix

• Kev Ntsuas Gradient LOI: 30%, 32%, 35% cov qauv sib xws
• Kev Txheeb Xyuas Tag Nrho UL94V-0 qib ntawm 1.6mm/3.2mm tuab
• Kev Tshuaj Xyuas Zoo ntawm Cov Txheej Char: SEM kev soj ntsuam ntawm cov txheej char ceev (pom zoo ≥80μm txheej txuas ntxiv)

1. Kev daws teeb meem kev them nyiaj rau kev ua haujlwm ntawm lub tshuab

• Kev Kho Kom Zoo Dua Elastic ModulusRau txhua 10% nce ntxiv ntawm cov tshuaj tiv thaiv hluav taws, ntxiv 1.5% DOP + 0.5% roj taum pauv epoxidized
• Kev Txhim Kho Lub Zog Cuam TshuamNtxiv 2% core-shell ACR impact modifier

IV. Cov Tswv Yim Txhim Kho Tus Nqi

1. Kev Hloov Khoom Siv Raw

• Aluminium Hypophosphite: Hloov tau txog li 30% nrog ammonium polyphosphate (tus nqi txo qis 20%, tab sis yuav tsum xav txog kev tiv thaiv dej)
• Zinc BorateSiv 4.5% zinc borate + 1.5% barium metaborate (txhim kho kev tshem pa luam yeeb)

1. Cov Kev Ntsuas Txo Tus Nqi Txheej Txheem

• Kev Siv Tshuab MasterbatchCov tshuaj tiv thaiv hluav taws ua ntej rau hauv 50% concentration masterbatch (txo kev siv zog ua haujlwm los ntawm 30%)
• Kev Siv Khoom Siv Rov Qab: Tso cai rau 5% rov sib tsoo ntxiv (yuav tsum tau 0.3% stabilizer replenishment)

V. Kev Tswj Xyuas Kev Pheej Hmoo

1. Kev Tiv Thaiv Kev Poob Qis ntawm Cov Khoom Siv

• Kev Soj Ntsuam Xyuas Qhov Yaj Viscosity Tiag TiagKev sim torque rheometer, qhov kev hloov pauv ntawm torque yuav tsum <5%
• Lub Tswv Yim Ceeb Toom XimNtxiv 0.01% pH qhia; qhov tsis zoo li qub ua rau kaw tam sim ntawd

1. Cov Kev Cai Tiv Thaiv Khoom Siv

• Cov Ntsia Hlau Chrome-PlatedTiv thaiv kom tsis txhob muaj kua qaub xeb (tshwj xeeb tshaj yog nyob rau hauv seem tuag)
• Lub Tshuab Dehumidification: Tswj qhov chaw ua haujlwm kom cov dej noo noo tsawg dua -20°C
