Ma awoodaan in Fosfooraska-Nitrogen-ka ay ku guuleystaan Qiimeynta V0 ee Cinjirka Silikoon?
Marka macaamiishu ay wax ka weydiiyaan isticmaalka kaliya isku-darka aluminium hypophosphite (AHP) ama AHP + MCA ee loogu talagalay dib-u-celinta ololka aan halogen lahayn ee caagga silikoon si loo gaaro qiimeynta V0, jawaabtu waa haa - laakiin hagaajinta qiyaasta ayaa loo baahan yahay iyadoo lagu saleynayo shuruudaha dib-u-celinta ololka. Hoos waxaa ku qoran talooyin gaar ah oo loogu talagalay xaalado kala duwan:
1. Isticmaalka Aluminium Hypophosphite (AHP) Keli ahaan
Xaaladaha khuseeya: Shuruudaha UL94 V-1/V-2 ama codsiyada xasaasiga u ah ilaha nitrogen (tusaale ahaan, ka fogaanshaha saameynta xumbo ka timaadda MCA ee saameyn karta muuqaalka).
Qaaciddada lagu taliyay:
- Cinjirka salka ah: Cinjirka silikoonka Methyl vinyl (VMQ, 100 phr)
- Aluminium hypophosphite (AHP): 20–30 hr
- Fosfooraska oo aad u sarreeya (40%); 20 phr wuxuu bixiyaa ~ 8% maadada fosfooraska ee loogu talagalay dib u dhigista ololka aasaasiga ah.
- UL94 V-0, kordhi ilaa 30 phr (waxay saameyn kartaa sifooyinka farsamada).
- Buuxiye xoojinaya: Silica la shiiday (10-15 phr, waxay ilaalisaa xooggeeda)
- Waxyaabaha lagu daro: Saliidda silikoonka ee Hydroxyl (2 phr, waxay wanaajisaa habaynta) + wakiilka bogsashada (nidaamka peroxide ama platinum)
Astaamaha:
- AHP kaliya waxay ku tiirsan tahay dib-u-celinta ololka wejiga la isku daray (samaynta dabeecadda), taasoo si weyn u hagaajinaysa tusmada oksijiinta (LOI) ee caagga silikoon laakiin leh xakamaynta qiiqa oo xaddidan.
- Qiyaasta sare (>25 phr) waxay kordhin kartaa adkeysiga walxaha; ku darista 3-5 phr zinc borate waxay hagaajin kartaa tayada lakabka char.
2. Isku-darka AHP + MCA
Xaaladaha khuseeya: Shuruudaha UL94 V-0, oo ujeedadoodu tahay qiyaas yar oo lagu daro oo leh isku-xidhka gaaska-wajiga dabka.
Qaaciddada lagu taliyay:
- Cinjirka salka: VMQ (100 phr)
- Aluminium hypophosphite (AHP): 12–15 hr
- Waxay xoojisaa habka dheef-shiidka waxayna ka hortagtaa sameynta fosfooraska.
- MCA: 8–10 hr
- Isha Nitrogen-ka waxay la shaqaysaa AHP (saamaynta PN), iyadoo sii deysa gaasaska aan firfircoonayn (tusaale ahaan, NH₃) si loo xakameeyo faafitaanka ololka.
- Buuxiye xoojinaya: Silica la shiiday (10 phr)
- Waxyaabaha lagu daro: Wakiilka isku xidhka Silane (1 phr, wuxuu hagaajiyaa kala firdhinta) + wakiilka bogsashada
Astaamaha:
- Wadarta qiyaasta daawada dab-damiska: ~20–25 phr, si weyn uga hooseeya AHP oo keliya.
- MCA waxay yareysaa qiyaasta AHP laakiin waxay si yar u saameyn kartaa hufnaanta (nano-MCA ayaa lagula talinayaa haddii hufnaanta loo baahdo).
3. Isbarbardhigga Halbeegga Muhiimka ah
| Qaaciddada | Dib-u-dhaca Ololka ee la filayo | Wadarta Qiyaasta (phr) | Faa'iidooyinka & Qasaarooyinka |
|---|---|---|---|
| AHP keliya (20 saacadood) | UL94 V-1 | 20 | Fudud, kharash yar; V-0 waxay u baahan tahay ≥30 phr, iyadoo waxqabadka hoos u dhacayo. |
| AHP keliya (30 saacadood) | UL94 V-0 | 30 | Dab-damis badan laakiin adkaanta ayaa korodhay iyo dhererka oo yaraada. |
| AHP 15 + MCA 10 | UL94 V-0 | 25 | Saameyn isku mid ah, waxqabad dheellitiran - ayaa lagula talinayaa tijaabooyinka bilowga ah. |
4. Talooyin Tijaabo ah
- Tijaabada mudnaanta leh ee AHP + MCA (15+10 phr): Haddii V-0 la gaaro, si tartiib tartiib ah u yaree AHP (tusaale ahaan, 12+10).
- Xaqiijinta AHP oo keliya: Ka bilow 20 phr, kordhi 5 phr imtixaankiiba si aad u qiimeyso LOI iyo UL94, la soco isbeddellada hantida farsamada.
- Baahida xakamaynta qiiqa: Ku dar 3-5 phr zinc borate qaacidooyinka kor ku xusan si loo yareeyo qiiqa iyada oo aan wax u dhimayn dabacsanaanta ololka.
5. Ammonium Polyphosphate oo dahaar leh
Waxaan haynaa macaamiil si guul leh u isticmaalaya TF-201G caagga silicon.
Si aad u sii wanaajiso, tixgeli inaad ku darto xaddi yar oo aluminium hydroxide ah (10-15 phr) si loo yareeyo kharashyada guud, inkastoo tani ay kordhinayso wadarta guud ee buuxinta.
