Ka taea e ngā ārai mura o te Phosphorus-Haitogen te whakatutuki i te whakatauranga V0 i roto i te rapa silicone?
Ina pātai mai ngā kaihoko mō te whakamahi i te konumohe hypophosphite (AHP) me ngā huinga AHP + MCA rānei mō te aukati mura kore-halogen i roto i te rapa silicone hei whakatutuki i te whakatauranga V0, ko te whakautu he āe—engari me whakarerekē te horopeta i runga i ngā whakaritenga aukati mura. Kei raro nei ngā taunakitanga motuhake mō ngā āhuatanga rerekē:
1. Te Whakamahi i te Konumohe Hypophosphite (AHP) Anake
Ngā āhuatanga e tika ana: Mō ngā whakaritenga UL94 V-1/V-2, mō ngā tono rānei e pāngia ana e ngā pūtake hauota (hei tauira, te karo i ngā pānga huka mai i te MCA ka pā kino ki te āhua).
Te hanganga i tūtohutia:
- Rapa turanga: Rapa methyl vinyl silicone (VMQ, 100 phr)
- Konumohe hypophosphate (AHP): 20–30 phr
- He nui te ihirangi phosphorus (40%); 20 phr e whakarato ana i te ~8% o te ihirangi phosphorus hei ārai i te mura taketake.
- Mō te UL94 V-0, whakapiki ake ki te 30 phr (tērā pea ka pā ki ngā āhuatanga ā-pūkaha).
- Whakakī whakapakari: Te silica kua whakakāhia (10–15 phr, ka mau tonu te kaha)
- Ngā Tāpiri: Hinu hydroxyl silicone (2 phr, whakapai ake i te tukatuka) + kaihoko whakamaroke (pūnaha peroxide, platinum rānei)
Ngā Āhuatanga:
- Ko te AHP anake e whakawhirinaki ana ki te ātete mura ā-wāhanga-whakapoto (te hanganga waro), ka whakapai ake i te taupū hāora (LOI) o te rapa silicone engari he iti noa te pehi paowa.
- Mā te horopeta nui (>25 phr) ka pakari ake te rauemi; mā te tāpiri i te 3–5 phr o te konutea borate ka pai ake te kounga o te paparanga waro.
2. Huinga AHP + MCA
Ngā āhuatanga e tika ana: Ngā whakaritenga UL94 V-0, e whai ana kia iti te horopeta tāpiri me te mahi tahi ātete mura hau-āhua.
Te hanganga i tūtohutia:
- Rapa turanga: VMQ (100 phr)
- Konumohe hypophosphate (AHP): 12–15 phr
- Ka whakarato i te pūtake o te whākōkī, ka whakatairanga i te hanganga waro.
- MCA: 8–10 ōrau
- Ka mahi tahi te pūtake hauota me te AHP (pānga PN), ka tukuna ngā hau kore mahi (hei tauira, NH₃) hei pehi i te horapa o te mura.
- Whakakī whakapakari: Hiraka kua pāngia (10 phr)
- Ngā Tāpiri: Kaihoko honohono silane (1 phr, whakapai ake i te horapa) + kaihoko whakamaroke
Ngā Āhuatanga:
- Te horopeta katoa o te ātete mura: ~20–25 phr, he iti iho i te AHP anake.
- Ka whakaitihia e te MCA te horopeta AHP engari ka pā pea ki te māramatanga (e taunakihia ana te nano-MCA mēnā e hiahiatia ana te māramatanga).
3. Whakataurite Tawhā Matua
| Te hanga | Te Ātete Mura e Tumanakohia ana | Inenga Katoa (phr) | Ngā Painga me ngā Huakore |
|---|---|---|---|
| AHP anake (20 phr) | UL94 V-1 | 20 | Māmā, iti te utu; e hiahiatia ana e te V-0 he ≥30 phr, ā, ka heke te mahi. |
| AHP anake (30 phr) | UL94 V-0 | 30 | He ātete mura nui engari he pakeke ake, he roa ake hoki. |
| AHP 15 + MCA 10 | UL94 V-0 | 25 | Pānga mahi tahi, mahi taurite—e taunakitia ana mō ngā whakamātautau tuatahi. |
4. Ngā Taunakitanga Whakamātautau
- Whakamātautau matua mō te AHP + MCA (15+10 phr): Ki te tutuki te V-0, whakaitihia mārire te AHP (hei tauira, 12+10).
- Manatoko AHP anake: Tīmata i te 20 phr, whakapiki ake mā te 5 phr mō ia whakamātautau hei aromatawai i te LOI me te UL94, me te aroturuki i ngā huringa āhuatanga miihini.
- Ngā mea e hiahiatia ana hei pehi i te paowa: Tāpirihia te 3–5 phr o te konutea borate ki ngā whakatakotoranga o runga ake nei hei whakaiti i te paowa, me te kore e whakararu i te ātete mura.
5. Ētahi Haukinia Polyphosphate Panipanihia
He maha ā mātou kiritaki kua angitu ki te whakamahi i te TF-201G mō te rapa silicon.
Hei whakapai ake i te kounga o te whakakī, whakaarohia te tāpiri i ngā iti noa o te konumohe hauwai (10–15 phr) hei whakaiti i ngā utu katoa, ahakoa ka piki ake te nui o te whakakī katoa.
