Xalka Habaysan ee Yaraynta Cufnaanta Filimka TPU

Xalka Habaysan ee Yaraynta Cufnaanta Filimka TPU (Hadda: 280; Bartilmaameedka: <200)
(Qaabka hadda jira: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Falanqaynta Arrinta Muhiimka ah

1. Xaddidaadda Habaynta Hadda:

• Aluminium hypophosphite: Ugu horrayn waxa ay joojisaa ololka fidsan laakiin waxa ay leedahay xakamaynta qiiqa xaddidan.
• MCA: Dib u dhiga holaca wejiga gaaska oo wax ku ool u ah dhalaalka ka dib (oo horeba ula kulmay yoolka) laakiin kuma filna dhimista qiiqa gubashada.
• Zinc borate: Waxay kor u qaadaa samaynta char laakiin aad ayay u yartahay (kaliya 2 phr), ku guul daraystay in ay samayso lakab cufan oo cufan si loo xakameeyo qiiqa.

1. Shuruudaha Muhiimka ah:

• Iska yaree cufnaanta qiiqa gubanayaxakamaynta qiiqa kor u kacayamahababka milanka gaaska-wajiga.

II. Xeeladaha Wanaajinta

1. Hagaajin Saamiyada Habaynta Jirta

• Aluminium hypophosphite: Kordhi ilaa18-20 saac(waxay kordhisaa dib u dhigista ololka wejiga-kooban; la soco dabacsanaanta).
• MCA: Kordhi ilaa6–8 saac(waxay kordhisaa ficil-waji-gaas; xaddi xad-dhaaf ah ayaa laga yaabaa inay hoos u dhigto habka).
• Zinc borate: Kordhi ilaa3–4 phr(waxay xoojisaa samaynta char).

Tusaale Qaabaynta La Habeeyay:

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

2. Soo bandhig dawooyinka qiiqa cabbista oo tayo sare leh

• Iskudhisyada Molybdenum(tusaale, zinc molybdate ama ammonium molybdate):
• Doorka: Waxa ay kicisaa samayska dhuxusha, isaga oo abuuraya caqabad cufan si uu u xidho qiiqa.
• Qiyaasta: 2-3 phr (waxay isku daraysaa zinc borate).
• Nanoclay (montmorillonite):
• DoorkaCaqabad jidheed si loo yareeyo sii daynta gaasta gubanaysa.
• Qiyaasta: 3-5 phr (dusha-dusha oo wax laga beddelay si loo kala firdhiyo).
• Dab-demiska dabka ku salaysan ee Silikoon:
• Doorka: Waxay wanaajisaa tayada dhuxusha iyo xakamaynta qiiqa.
• Qiyaasta: 1-2 phr (waxay ka ilaalisaa luminta daahfurnaanta).

3. Hagaajinta Nidaamka Isku-dhafka

• Zinc borateKu dar 1–2 phr si aad ula mid noqoto aluminium hypophosphite iyo zinc borate.
• Ammonium polyphosphate (APP)Ku dar 1–2 phr si aad kor ugu qaaddo ficilka wajiga gaaska ee MCA.

III. Habaynta Dhamaystiran ee lagu taliyay

Natiijooyinka la filayo:

• Cufnaanta qiiqa gubanaya: ≤200 (iyada oo loo marayo char + isugeynta wejiga gaaska).
• Cufnaanta qiiqa dhalaalaysa: ilaali ≤200 (MCA + borate zinc).

IV. Qoraallada Hagaajinta Habraaca Furaha

1. Habaynta Heerkulka: Ilaali 180-200C si aad uga hortagto burburka ololka ee dhicisoobay.
2. Kala firdhiso:

• Isticmaal isku-darka xawaaraha sare leh (≥2000 rpm) qaybinta nanoclay/molybdate lebbiska ah.
• Ku dar 0.5-1 phr wakiilka isku xirka silane (tusaale, KH550) si loo horumariyo ku haboonaanta buuxinta.

1. Sameynta Filimka: Qaadista, yaree heerka qaboojinta si loo fududeeyo samaynta lakabka char.

V. Tallaabooyinka Xaqiijinta

1. Tijaabada ShaybaarkaDiyaarso muunado qaabkii lagu taliyey; Samee UL94 gubashada tooska ah iyo tijaabooyinka cufnaanta qiiqa (ASTM E662).
2. Dheelitirnaanta WaxqabadkaTijaabi xoogga xajinta, dhererka, iyo daahfurnaanta.
3. Kordhinta is-beddelka: Haddii cufnaanta qiiqa uu weli sarreeyo, si kordhin u hagaaji molybdate ama nanoclay (± 1 phr).

VI. Qiimaha & Suurtogalnimada

• Saamaynta Qiimaha: Zinc molybdate (~¥50/kg) + nanoclay (~¥30/kg) waxay kordhisaa wadarta qiimaha <15% at ≤10% rarida.
• Miisaanka warshadaha: La jaan qaada habka caadiga ah ee TPU; looma baahna qalab gaar ah.

VII. Gabagabo

Bysii kordhaya zinc borate + ku darista molybdate + nanoclay, nidaam saddex-laab ah (samaynta char + qasida gaaska + xannibaad jidheed) wuxuu gaari karaa bartilmaameedka cufnaanta qiiqa gubashada (≤200). Mudnaanta sii tijaabintamolybdate + nanoclayisku darka, ka dibna si fiican u habayn saamiga dheelitirka-waxqabadka kharashka.
