Tharollo e Hlophisitsoeng ea ho Fokotsa TPU Film Density ea Mosi

Tharollo e Hlophisitsoeng ea ho Fokotsa TPU Film Density Smoke (Hona joale: 280; Sepheo: <200)
(Moetso oa hajoale: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Tlhahlobo ea Taba ea Motheo

1. Meeli ea Tlhahiso ea Hona Joale:

• Hypophosphite ea aluminium: Haholo-holo e hatella ho ata ha lelakabe empa e na le khatello e fokolang ea mosi.
• MCA: Sehlahisoa sa lelakabe sa khase se sebetsang hantle bakeng sa ho khantša ka morao (se se se fihletse sepheo) empa se sa lekana bakeng sa ho fokotsa mosi o tukang.
• Zinc borate: E khothalletsa tlhahiso ea char empa e fokotsoe (2 phr feela), e hloleha ho theha char layer e lekaneng ho thibela mosi.

1. Tlhokahalo ea Bohlokoa:

• Fokotsa mosi o tukang ka ho sebelisakhatello e matlafalitsoeng ea mosikapamekhoa ea khase ea khase.

II. Mekhoa ea ho ntlafatsa

1. Fetola Litekanyetso tse Teng tsa Tlhahiso

• Hypophosphite ea aluminium: Eketsa ho18-20 phr(e ntlafatsa ho lieha ha lelakabe la condensed-phase; hlokomela ho feto-fetoha ha maemo).
• MCA: Eketsa ho6-8 phr(e matlafatsa ts'ebetso ea khase; chelete e ngata haholo e ka senya ts'ebetso).
• Zinc borate: Eketsa ho3–4 phr(e matlafatsa sebopeho sa char).

Moetso o Fetoletsoeng:

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

2. Hlahisa Lithethefatsi tsa Mosi tse sebetsang hantle haholo

• Metsoako ea molybdenum(mohlala, zinc molybdate kapa ammonium molybdate):
• Karolo: E matlafatsa sebopeho sa char, e theha tšitiso e teteaneng ho thibela mosi.
• Tekanyetso: 2–3 phr (e kopanya le zinki borate).
• Nanoclay (montmorillonite):
• Karolo: Tšitiso ea 'mele ea ho fokotsa ho lokolloa ha khase e tukang.
• Tekanyetso: 3–5 phr (boholimo-bo fetotsoe bakeng sa ho hasana).
• Li-retardants tsa lelakabe tse thehiloeng ho silicone:
• Karolo: E ntlafatsa boleng ba char le khatello ea mosi.
• Tekanyetso: 1–2 phr (e qoba tahlehelo ea pepenene).

3. Synergistic System Optimization

• Zinc borate: Eketsa 1–2 phr ho hokahanya le aluminium hypophosphite le zinki borate.
• Ammonium polyphosphate (APP): Kenya 1–2 phr ho ntlafatsa khato ea khase ka MCA.

III. Recommended Comprehensive Formation

Liphetho tse Lebeletsoeng:

• Boima ba mosi o tukang: ≤200 (ka char + khase-phase synergy).
• Bongata ba mosi oa afterglow: Boloka ≤200 (MCA + zinki borate).

IV. Lintlha tsa Ntlafatso ea Ts'ebetso ea Bohlokoa

1. Mocheso oa ho sebetsa: Boloka mocheso oa 180-200 ° C ho thibela ho senyeha ho sa lebelloang ho sa lebelloang.
2. Phasano:

• Sebelisa ho kopanya ka lebelo le phahameng (≥2000 rpm) bakeng sa kabo ea nanoclay / molybdate e tšoanang.
• Kenya 0.5–1 phr silane coupling agent (mohlala, KH550) ho ntlafatsa tšebelisano ea li-filler.

1. Tlhahiso ea Lifilimi: Bakeng sa ho lahlela, fokotsa sekhahla sa ho pholisa ho thusa ho theha char layer.

V. Mehato ea ho netefatsa

1. Tlhahlobo ea Lab: Lokisetsa lisampole ka mokhoa o khothaletsoang; etsa liteko tsa UL94 tsa ho chesa le ho chesoa ha mosi (ASTM E662).
2. Tekanyo ea Ts'ebetso: Lekola matla a ho tiea, bolelele, le ponaletso.
3. Phethahatso e Ikemetseng: Haeba boima ba mosi bo lula bo le holimo, fetola molybdate kapa nanoclay ka ho eketseha (± 1 phr).

VI. Litšenyehelo & Ho khoneha

• Tšusumetso ea Litšenyehelo: Zinc molybdate (~ ¥50 / kg) + nanoclay (~ ¥30 / kg) eketsa litšenyehelo tsohle ka <15% ho ≤10% ho kenya.
• Indasteri Scalability: E lumellana le ts'ebetso e tloaelehileng ea TPU; ha ho lisebelisoa tse khethehileng tse hlokahalang.

VII. Qetello

Kaho eketsa zinki borate + ho eketsa molybdate + nanoclay, tsamaiso ea liketso tse tharo (sebopeho sa char + dilution ea khase + mokoallo oa 'mele) e ka finyella sepheo sa sepheo sa ho chesa mosi (≤200). Beha pele liteko tsamolybdate + nanoclaymotsoako, ebe o etsa litekanyo tse nepahetseng bakeng sa tekanyo ea ts'ebetso ea litšenyehelo.
