Uburyo bwo kugabanya ubucucike bw'umwotsi wa TPU Film

Uburyo bwo kugabanya ubucucike bw'umwotsi wa TPU Film (Ubusanzwe: 280; Intego: <200)
(Ubu buryo bugezweho: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Isesengura ry'Ikibazo cy'Ingenzi

1. Imbogamizi z'uburyo bwo gukora ubu:

• Hypophosfite ya aluminiyumu: Mbere na mbere igabanya ikwirakwira ry'umuriro ariko igabanya umwotsi muke.
• MCA: Umuriro ugabanya ikirere ukoresheje gazi (gas phase) ufasha mu kugabanya umwijima nyuma y’aho uturutse (wamaze kugera ku ntego) ariko ntuhagije mu kugabanya umwotsi utwika.
• Borate ya zinki: Itera imbere kurema kwa char ariko igabanywa dose nkeya (dose 2 gusa), ntikora urwego rw'icyar ruhagije kugira ngo ihagarike umwotsi.

1. Ibisabwa by'ingenzi:

• Gabanya ubucucike bw'umwotsi utwika ukoreshejekugabanya umwotsi mu buryo bwa "char-enhanced char"cyangwauburyo bwo gusohora gazi mu cyiciro cya gazi.

II. Ingamba zo kunoza imikorere

1. Hindura ibipimo by'ikoreshwa ry'ibinyabutabire biriho

• Hypophosfite ya aluminiyumu: Ongera kuriIbice 18–20(yongerera ubushobozi bwo kudakoresha umuriro mu gihe cy'ingufu; igenzura imiterere y'umuriro).
• MCA: Ongera kuriIbice 6–8(byongera imbaraga mu mikorere ya gaze; ingano irenze urugero ishobora kwangiza itunganywa).
• Borate ya zinki: Ongera kuriIbice 3–4(bikomeza imiterere y'inyuguti).

Urugero rw'ikoreshwa ryahinduwe:

• Hypophosfite ya aluminiyumu: 18 phr
• MCA: 7 phr
• Borate ya zinki: 4 phr

2. Shyiramo imiti igabanya umwotsi neza cyane

• Ibinyabutabire bya Molybdenum(urugero, zinc molybdate cyangwa amonium molybdate):
• Uruhare: Itera imbaraga mu kurema ibara ry'umukara, igatuma habaho uruzitiro rurerure rwo gukumira umwotsi.
• Igipimo: 2–3 phr (ihuza na zinc borate).
• Nanoclay (montmorillonite):
• Uruhare: Inzitizi ifatika yo kugabanya isohoka ry'imyuka ishobora gushya.
• Igipimo: 3–5 phr (yahinduwe ku buso kugira ngo ikwirakwizwe).
• Ibintu bigabanya umuriro bishingiye kuri silikoni:
• Uruhare: Yongera ubwiza bw'isuku no kugabanya umwotsi.
• Igipimo: 1–2 phr (yirinda gutakaza ubushobozi bwo gukorera mu mucyo).

3. Guteza imbere sisitemu ihuriweho

• Borate ya zinki: Ongeraho 1–2 phr kugira ngo ihuzwe na aluminium hypophosphite na zinc borate.
• Ammonium polyphosphate (APP): Ongeraho 1–2 phr kugira ngo wongere imikorere ya gas-phase hamwe na MCA.

III. Uburyo bwo gusesengura busabwa ku buryo burambuye

Ibisubizo byitezwe:

• Ubucucike bw'umwotsi utwika: ≤200 (binyuze kuri char + ubufatanye bwa gaze-phase).
• Ubucucike bw'umwotsi nyuma y'urumuri: Gufata ≤200 (MCA + zinc borate).

IV. Inyandiko z'ingenzi zo kunoza inzira

1. Ubushyuhe bwo gutunganya: Bika ubushyuhe bwa 180–200°C kugira ngo wirinde ko umuriro utangira kubora.
2. Gutatana:

• Koresha uburyo bwo kuvanga bukoresha umuvuduko mwinshi (≥2000 rpm) kugira ngo ukoreshe nanoclay/molybdate imwe.
• Ongeraho 0.5–1 phr silane coupling agent (urugero, KH550) kugira ngo wongere ubwuzuzanye bw'ibinure.

1. Gutunganya filime: Ku bijyanye no gusuka, gabanya igipimo cyo gukonjesha kugira ngo worohereze ikorwa ry'urutonde rw'ibumba.

V. Intambwe zo kwemeza

1. Gupima muri laboratwari: Tegura ingero hakurikijwe uburyo bwatanzwe; kora ibizamini bya UL94 byo gutwika no gupima ubucucike bw'umwotsi (ASTM E662).
2. Ingano y'Imikorere: Gerageza imbaraga zo gukurura, kurekura, no kubona ibintu mu buryo buboneye.
3. Guhindura Iterambere: Niba ubucucike bw'umwotsi bukomeje kuba bwinshi, hindura buhoro buhoro molybdate cyangwa nanoclay (± 1 phr).

VI. Ikiguzi n'ubushobozi bwo gukora

• Ingaruka ku Giciro: Zinc molybdate (~¥50/kg) + nanoclay (~¥30/kg) byongera ikiguzi cyose ho <15% kuri ≤10% by'umubyigano.
• Uburyo bwo kwagura inganda: Ihuye n'uburyo busanzwe bwo gutunganya TPU; nta bikoresho byihariye bikenewe.

VII. Umwanzuro

Kugeza kurikongera zinc borate + kongeramo molybdate + nanoclay, sisitemu y'ibikorwa bitatu (ikorwa ry'ibara ry'umukara + igabanuka ry'umwuka + imbogamizi ifatika) ishobora kugera ku bucucike bw'umwotsi utwikwa (≤200). Shyira imbere igeragezamolybdate + nanoclayguhuza, hanyuma utunganye ibipimo by'ikiguzi n'imikorere.
