Kev daws teeb meem tsis tu ncua rau kev txo qhov ceev ntawm TPU zaj duab xis pa luam yeeb (Tam sim no: 280; Lub hom phiaj: <200)
(Cov mis tam sim no: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Kev Tshawb Fawb Txog Qhov Teeb Meem Tseem Ceeb

1. Cov Kev Txwv ntawm Cov Qauv Tam Sim No:

• Aluminium hypophosphite: Feem ntau tiv thaiv hluav taws kom tsis txhob kis mus tab sis nws tiv thaiv pa luam yeeb tau tsawg.
• MCA: Ib qho tshuaj tiv thaiv hluav taws uas siv roj ua haujlwm tau zoo rau qhov kub tom qab (twb ua tiav lub hom phiaj lawm) tab sis tsis txaus rau kev txo cov pa luam yeeb.
• Zinc borateTxhawb kom muaj cov char tab sis tsis tau noj ntau dhau (tsuas yog 2 phr xwb), ua rau tsis muaj cov char txaus kom tshem tau cov pa luam yeeb.

1. Qhov Yuav Tsum Tau Ua:

• Txo qhov ceev ntawm cov pa luam yeeb los ntawmkev tshem tawm pa luam yeeb uas muaj char ntau dualos yogCov txheej txheem dilution roj-theem.

II. Cov Tswv Yim Txhim Kho

1. Kho Cov Qauv Uas Muaj Lawm

• Aluminium hypophosphite: Nce mus rau18–20 teev sawv ntxov(ua kom cov nplaim taws tsis kam ntawm cov khoom sib xyaw ua ke; saib xyuas kev ywj pheej).
• MCA: Nce mus rau6–8 phr(ua kom cov roj ua haujlwm zoo dua; ntau dhau yuav ua rau cov txheej txheem ua haujlwm tsis zoo).
• Zinc borate: Nce mus rau3–4 phr(ua kom cov char tsim muaj zog).

Piv txwv li Kev Kho Dua Qauv:

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

2. Taw qhia cov tshuaj tua pa luam yeeb zoo heev

• Cov tshuaj molybdenum(xws li zinc molybdate lossis ammonium molybdate):
• Lub Luag Haujlwm: Ua rau muaj cov pa roj av, tsim kom muaj ib daim ntaub thaiv ntom ntom los thaiv cov pa luam yeeb.
• Kev Siv Tshuaj: 2–3 phr (synergizes nrog zinc borate).
• Nanoclay (montmorillonite):
• Lub Luag Haujlwm: Kev thaiv lub cev kom txo cov pa roj uas yooj yim hlawv.
• Kev Siv Tshuaj: 3–5 phr (hloov kho qhov chaw rau kev sib kis).
• Cov tshuaj tiv thaiv hluav taws uas ua los ntawm silicone:
• Lub Luag Haujlwm: Txhim kho qhov zoo ntawm cov char thiab kev tswj pa luam yeeb.
• Kev Siv Tshuaj1–2 phr (zam tsis txhob poob pob tshab).

3. Kev Txhim Kho Lub Cev Sib Koom Tes

• Zinc borateNtxiv 1–2 phr kom sib xyaw nrog txhuas hypophosphite thiab zinc borate.
• Ammonium polyphosphate (APP)Ntxiv 1–2 phr kom txhim kho kev ua haujlwm ntawm theem roj nrog MCA.

III. Cov Qauv Uas Pom Zoo Kom Ua Tau Zoo

Cov Txiaj Ntsig Xav Tau:

• Cov pa luam yeeb kub hnyiab: ≤200 (ntawm char + roj-theem synergy).
• Qhov ceev ntawm cov pa luam yeeb tom qab ci ntsa iab: Tswj ≤200 (MCA + zinc borate).

IV. Cov Lus Qhia Txog Kev Txhim Kho Cov Txheej Txheem Tseem Ceeb

1. Kub Ua HaujlwmKub: Tswj kom 180–200°C kom tiv thaiv kom tsis txhob lwj ua ntej lub sijhawm uas hluav taws kub hnyiab.
2. Kev tawg tawm:

• Siv kev sib tov ceev ceev (≥2000 rpm) rau kev faib tawm nanoclay/molybdate sib xws.
• Ntxiv 0.5–1 phr silane coupling agent (piv txwv li, KH550) los txhim kho kev sib raug zoo ntawm cov khoom sau.

1. Kev Tsim Yeeb YamRau kev casting, txo qhov txias kom yooj yim rau kev tsim cov char txheej.

V. Cov Kauj Ruam Txheeb Xyuas

1. Kev Kuaj Hauv Chav Kuaj MobNpaj cov qauv raws li cov qauv pom zoo; ua qhov kev sim hlawv ntsug thiab pa luam yeeb ceev UL94 (ASTM E662).
2. Kev Ua Tau Zoo Sib Npaug: Sim lub zog tensile, elongation, thiab transparency.
3. Kev Txhim Kho Dua TshiabYog tias cov pa luam yeeb tseem siab, maj mam kho molybdate lossis nanoclay (± 1 phr).

VI. Tus nqi thiab kev ua tau

• Kev Cuam Tshuam ntawm Tus NqiZinc molybdate (~ ¥50/kg) + nanoclay (~ ¥30/kg) ua rau tag nrho cov nqi nce ntxiv <15% ntawm ≤10% loading.
• Kev Loj Hlob ntawm Kev Lag Luam: Sib xws nrog tus qauv TPU ua tiav; tsis tas yuav muaj cov khoom siv tshwj xeeb.

VII. Xaus Lus

Los ntawmnce zinc borate + ntxiv molybdate + nanoclay, ib qho kev ua haujlwm peb zaug (Kev tsim cov char + kev dilution roj + kev thaiv lub cev) tuaj yeem ua tiav qhov ceev ntawm cov pa luam yeeb uas tau teeb tsa (≤200). Muab qhov tseem ceeb rau kev simmolybdate + nanoclaykev sib xyaw ua ke, tom qab ntawd kho cov piv kom zoo rau kev sib npaug ntawm tus nqi thiab kev ua tau zoo.
