Xal Nidaamsan oo lagu Yaraynayo Cufnaanta Qiiqa Filimka TPU

Xal Nidaamsan oo lagu Yaraynayo Cufnaanta Qiiqa Filimka TPU (Hadda: 280; Bartilmaameed: <200)
(Qaabka hadda jira: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Falanqaynta Arrimaha Muhiimka ah

1. Xaddidaadaha Qaabaynta Hadda:

• Aluminium hypophosphite: Waxay ugu horreyn xakameysaa faafitaanka ololka laakiin waxay leedahay xakameyn xaddidan oo qiiqa ah.
• MCA: Qalab gaas-waji ah oo wax ku ool u ah iftiinka dambe (horeba u daboolay bartilmaameedka) laakiin aan ku filnayn yaraynta qiiqa gubashada.
• Zinc borate: Waxay kor u qaadaa sameynta char laakiin waa la yareeyay (kaliya 2 phr), iyadoo aan sameynin lakab char oo ku filan oo cufan si loo xakameeyo qiiqa.

1. Shuruudaha Muhiimka ah:

• Yaree cufnaanta qiiqa gubashada iyada oo loo marayoxakamaynta qiiqa oo si fiican loo xoojiyayamafarsamooyinka kala-soocidda wejiga gaaska.

II. Istaraatiijiyadaha Hagaajinta

1. Hagaaji Saamiyada Qaaciddada ee Jira

• Aluminium hypophosphiteKordhi ilaa18–20 fiidnimo(waxay kor u qaadaysaa dib u dhigista ololka wejiga la isku daray; la soco dabacsanaanta).
• MCAKordhi ilaa6–8 fiidnimo(waxay kor u qaaddaa ficilka marxaladda gaaska; xaddi badan ayaa laga yaabaa inay hoos u dhigto habaynta).
• Zinc borateKordhi ilaa3–4 saacadood(waxay xoojisaa sameynta hiddaha).

Tusaalaha Qaabaynta La Hagaajiyay:

• Aluminium hypophosphite: 18 saacadood
• MCA: 7 fiidnimo
• Zinc borate: 4 saacadood

2. Soo Bandhig Daawooyinka Cabbiyaha Qiiqa ee Waxtarka Sare leh

• Isku-dhafka Molybdenum(tusaale, zinc molybdate ama ammonium molybdate):
• Doorka: Waxay kicisaa sameynta wasakhda, iyadoo abuurta caqabad cufan si loo joojiyo qiiqa.
• Qiyaasta: 2–3 phr (wuxuu la shaqeeyaa zinc borate).
• Nanoclay (montmorillonite):
• Doorka: Caqabad jireed si loo yareeyo sii deynta gaaska guban kara.
• Qiyaasta: 3–5 phr (dusha sare wax laga beddelay si loo kala firdhiyo).
• Daawooyinka dab-damiya ee ku salaysan silikoon:
• Doorka: Waxay hagaajisaa tayada kulaylka iyo xakamaynta qiiqa.
• Qiyaasta: 1–2 phr (wuxuu ka hortagaa luminta hufnaanta).

3. Hagaajinta Nidaamka Isku-dhafka ah

• Zinc borate: Ku dar 1–2 phr si aad ula falgasho aluminium hypophosphite iyo zinc borate.
• Ammonium polyphosphate (APP): Ku dar 1–2 phr si aad u xoojiso ficilka marxaladda gaaska iyadoo la adeegsanayo MCA.

III. Qaacido Dhammaystiran oo lagu taliyay

Natiijooyinka la filayo:

• Cufnaanta qiiqa gubanaya: ≤200 (iyada oo loo marayo isku-dhafka char + gaaska-wajiga).
• Cufnaanta qiiqa ka dib iftiinka: Ku hay ≤200 (MCA + zinc borate).

IV. Qoraallada Muhiimka ah ee Hagaajinta Habka

1. Heerkulka Habaynta: Ku hay 180–200°C si looga hortago burburka ololka ee dhicisoobay.
2. Kala Fidsanaan:

• Isticmaal isku-darka xawaaraha sare leh (≥2000 rpm) si aad u hesho qaybinta nanoclay/molybdate oo isku mid ah.
• Ku dar wakiilka isku xidhka 0.5–1 phr silane (tusaale ahaan, KH550) si loo hagaajiyo iswaafajinta buuxinta.

1. Samaynta Filimada: Si aad u shubto, yaree heerka qaboojinta si aad u fududeyso sameynta lakabka char.

V. Tallaabooyinka Xaqiijinta

1. Baaritaanka Shaybaarka: Diyaari muunado sida ku xusan qaacidada lagu taliyay; samee tijaabooyinka gubashada toosan iyo cufnaanta qiiqa ee UL94 (ASTM E662).
2. Dheelitirka Waxqabadka: Tijaabi xoogga jiidista, dheereynta, iyo hufnaanta.
3. Hagaajinta Soo Noqnoqda: Haddii cufnaanta qiiqu ay sarreyso, si tartiib tartiib ah u hagaaji molybdate ama nanoclay (±1 phr).

VI. Qiimaha & Suurtagalnimada

• Saamaynta Kharashka: Zinc molybdate (~ ¥ 50/kg) + nanoclay (~ ¥ 30/kg) waxay kordhisaa wadarta kharashka iyadoo <15% marka la raro ≤10%.
• Cabbiraadda Warshadaha: Ku habboon habaynta TPU-ga caadiga ah; qalab gaar ah looma baahna.

VII. Gunaanad

Bykordhinta zinc borate + ku darista molybdate + nanoclay, nidaam saddex-fal ah (sameynta dabeecadda + kala-baxa gaaska + caqabad jireed) waxay gaari kartaa cufnaanta qiiqa gubashada ee bartilmaameedka ah (≤200). Mudnaanta sii tijaabintamolybdate + nanoclayisku darka, ka dibna si fiican u hagaaji saamiga dheelitirka kharashka iyo waxqabadka.
