Ese Fosifore-Azote Flame Retardants ishobora kugera ku gipimo cya V0 muri Rubber ya Silicone?
Iyo abakiriya babajije ibijyanye no gukoresha gusa aluminium hypophosphite (AHP) cyangwa AHP + MCA ikomatanyirijwe hamwe na halogen idafite flame retardancy muri rubber ya silicone kugirango igere ku gipimo cya V0, igisubizo ni yego - ariko birakenewe ko hahindurwa dosiye hashingiwe kubisabwa kugirango umuriro ubuze. Hano haribisobanuro byihariye kubintu bitandukanye:
1. Gukoresha Aluminium Hypophosphite (AHP) Wenyine
Ibihe byakurikizwa: Kubisabwa UL94 V-1 / V-2 cyangwa porogaramu zumva amasoko ya azote (urugero, kwirinda ingaruka zifuro zituruka kuri MCA zishobora kugira ingaruka kumiterere).
Basabwe gukora:
- Rubber shingiro: Methyl vinyl silicone reberi (VMQ, interuro 100)
- Aluminium hypophosphite (AHP): interuro 20-30
- Ibirimo fosifore nyinshi (40%); Imvugo 20 itanga ~ 8% ya fosifore yibikoresho byibanze bya flame.
- Kuri UL94 V-0, ongera kuri 30 interuro (irashobora kugira ingaruka kumiterere).
- Kuzuza ibyuzuzo: silika yuzuye (interuro 10-15, ikomeza imbaraga)
- Ibyongeweho: Amavuta ya Hydroxyl silicone (interuro 2, atezimbere gutunganya) + imiti ikiza (sisitemu ya peroxide cyangwa platine)
Ibiranga:
- AHP yonyine yishingikiriza ku cyiciro cya flame retardancy (char form), itezimbere cyane ogisijeni (LOI) ya reberi ya silicone ariko ikumira umwotsi muke.
- Igipimo kinini (> 25 interuro) gishobora kongera ubukana bwibintu; wongeyeho 3-5 interuro zinc borate irashobora kuzamura ubwiza bwa char layer.
2. Guhuza AHP + MCA
Ibikurikizwa: UL94 V-0 ibisabwa, bigamije kugabanura dosiye nkeya hamwe na gaz-fase flame retardant synergy.
Basabwe gukora:
- Rubber shingiro: VMQ (interuro 100)
- Aluminium hypophosphite (AHP): interuro 12-15
- Itanga isoko ya fosifore, iteza imbere gushiraho char.
- MCA: 8-10 interuro
- Inkomoko ya azote ihuza na AHP (PN ingaruka), irekura imyuka ya inert (urugero, NH₃) kugirango ihagarike ikwirakwizwa ryumuriro.
- Kuzuza ibyuzuzo: silika yuzuye (interuro 10)
- Inyongeramusaruro: Umukozi wo guhuza Silane (interuro 1, atezimbere gutatanya) + imiti ikiza
Ibiranga:
- Igipimo cya flame retardant dosage: ~ 20-25 interuro, munsi cyane ya AHP yonyine.
- MCA igabanya dosiye ya AHP ariko irashobora kugira ingaruka nkeya mumucyo (nano-MCA isabwa niba gukorera mu mucyo bisabwa).
3. Kugereranya Ibyingenzi Kugereranya
| Gutegura | Biteganijwe ko Flame idindira | Umubare wuzuye (interuro) | Ibyiza & Ibibi |
|---|---|---|---|
| AHP wenyine (interuro 20) | UL94 V-1 | 20 | Biroroshye, igiciro gito; V-0 isaba ≥30 interuro, hamwe no gutesha agaciro imikorere. |
| AHP wenyine (30 interuro) | UL94 V-0 | 30 | Umuriro mwinshi cyane ariko wongereye ubukana no kugabanya kuramba. |
| AHP 15 + MCA 10 | UL94 V-0 | 25 | Ingaruka ya synergiste, imikorere iringaniye-isabwa kubigeragezo byambere. |
4. Ibyifuzo byubushakashatsi
- Ikizamini cyibanze kuri AHP + MCA (15 + 10 interuro): Niba V-0 igerwaho, gabanya buhoro buhoro AHP (urugero, 12 + 10).
- AHP yonyine igenzura: Tangira kuri 20 interuro, ongeraho interuro 5 kuri buri kizamini kugirango usuzume LOI na UL94, ukurikirane impinduka zumutungo wubukanishi.
- Kurwanya umwotsi bikenewe: Ongeramo 3-5 interuro ya zinc borate kumurongo wavuzwe haruguru kugirango ugabanye umwotsi utabangamiye ububi bwa flame.
5. Bimwe mu Bifunitse Amonium Polyphosifate
Dufite abakiriya bamwe bakoresha neza TF-201G kuri reberi ya silicon.
Kugirango urusheho kunozwa, tekereza gushyiramo hydroxide ya aluminium (10-15) kugirango ugabanye ibiciro muri rusange, nubwo ibi byongera ibyuzuye.
