Dib-u-celiyayaasha Ololka Fosfooraska-Nitrogen-ku ma ku gaadhi karaan Qiimaynta V0 ee Rubber Silicone?
Marka macaamiishu wax ka weydiiyaan isticmaalka kaliya aluminium hypophosphite (AHP) ama AHP + MCA isku darka loogu talagalay dib u dhigista ololka halogen-la'aanta ee caagga silikoon si loo gaaro qiimeynta V0, jawaabtu waa haa-laakin hagaajin qiyaasta ayaa loo baahan yahay iyadoo lagu saleynayo shuruudaha dib u dhigista ololka. Hoos waxaa ah talooyinka gaarka ah ee xaaladaha kala duwan:
1. Isticmaalka Aluminium Hypophosphite (AHP) Kalidaa
Xaaladaha lagu dabaqi karo: Shuruudaha UL94 V-1/V-2 ama codsiyada xasaasiga u ah ilaha nitrogen (tusaale, ka fogaanshaha saamaynta xumbo ee MCA ee laga yaabo inay saamayso muuqaalka).
Habka lagu taliyay:
- Caag-saldhig: caag silikoon ah oo vinyl vinyl ah (VMQ, 100 phr)
- Aluminium hypophosphite (AHP): 20-30 phr
- Maadada fosfooraska sare (40%); 20 phr waxay siisaa ~ 8% maadada fosfooraska dib u dhacyada aasaasiga ah ee ololka.
- Wixii ah UL94 V-0, kor u kaca ilaa 30 phr (waxa laga yaabaa inay saamayso sifooyinka farsamada).
- Buuxiyaha xoojinta: silica qiiqaysan (10-15 phr, waxay ilaalisaa awoodda)
- Waxyaalaha lagu daro: Saliida silikoon ee Hydroxyl (2 phr, waxay wanaajisaa habaynta) + wakiilka daawada (peroxide ama nidaamka platinum)
Astaamaha:
- AHP kaligiis waxay ku tiirsan tahay dib u dhigista ololka wajiga-kooban (samaynta char), si weyn u wanaajinaya tusmada ogsijiinta (LOI) ee cinjirka silikoon laakiin leh xakamaynta qiiqa xaddidan.
- Qiyaasta sare (> 25 phr) waxay kordhin kartaa adkaanta walxaha; ku darida 3-5 phr zinc borate waxay hagaajin kartaa tayada lakabka char.
2. AHP + MCA Isku-dhafka
Xaaladaha lagu dabaqi karo: Shuruudaha UL94 V-0, ujeedadeedu tahay qiyaas yar oo lagu daro oo leh is-dhexgal gaas-waji-gaas ah.
Habka lagu taliyay:
- Caag salka: VMQ (100 phr)
- Aluminium hypophosphite (AHP): 12-15 phr
- Waxay bixisaa isha fosfooraska, waxay kor u qaadaa samaynta char.
- MCA: 8-10 phr
- Isha Nitrogen waxay la midowdaa AHP (saamaynta PN), oo sii daysay gaasas aan shaqayn (tusaale, NH₃) si loo xakameeyo fiditaanka ololka.
- Buuxiyaha xoojinta: silica la shiiday (10 phr)
- Waxyaabaha lagu daro: Wakiilka isku xirka Silane (1 phr, waxay hagaajisaa kala firdhisanaanta) + wakiilka daweynta
Astaamaha:
- Wadarta qiyaasta dib u dhigista ololka: ~ 20-25 phr, aad uga hooseeya AHP oo keliya.
- MCA waxay yaraynaysaa qiyaasta AHP laakiin waxa laga yaabaa inay wax yar saamayso daahfurnaanta (nano-MCA ayaa lagu taliyay haddii loo baahdo daahfurnaan).
3. Isbarbardhigga Halbeegga Furaha
| Samaynta | Dib u dhaca Ololka ee la filayo | Wadarta qiyaasta qiyaasta (phr) | Faa'iidooyinka & Khasaarooyinka |
|---|---|---|---|
| AHP kali ah (20 phr) | UL94 V-1 | 20 | Fudud, qiimo jaban; V-0 waxay u baahan tahay ≥30 phr, oo leh hoos u dhac ku yimaada waxqabadka. |
| AHP kali ah (30 phr) | UL94 V-0 | 30 | Dib u dhac holac oo sarreeya laakiin adkaanta oo kordhay iyo dhererka oo yaraada. |
| AHP 15 + MCA 10 | UL94 V-0 | 25 | Saamaynta isku-dhafka ah, waxqabadka dheellitiran-waxaa lagu talinayaa tijaabooyinka bilowga ah. |
4. Talooyin tijaabo ah
- Imtixaanka mudnaanta leh ee AHP + MCA (15+10 phr): Haddii V-0 la gaaro, si tartiib tartiib ah u yaree AHP (tusaale, 12+10).
- Xaqiijinta AHP oo keliya: Ka bilow 20 phr, ku kordhi 5 phr imtixaankiiba si loo qiimeeyo LOI iyo UL94, la socodka isbeddelada hantida farsamada.
- Baahida xakamaynta qiiqa: Ku dar 3-5 phr zinc borate hababka kor ku xusan si loo yareeyo qiiqa iyada oo aan waxyeello u geysanaynin dib u dhaca ololka.
5. Qaar ka mid ah Ammonium Polyphosphate oo dahaaran
Waxaan leenahay macaamiisha qaarkood si guul leh u isticmaalaya TF-201G caag silikon.
Si loo hagaajiyo, tixgeli in lagu daro xaddi yar oo aluminium hydroxide ah (10-15 phr) si loo yareeyo kharashyada guud, in kasta oo tani ay kordhinayso wadarta guud ee buuxinta.
