Ko te taapiri o te konumohe hypophosphite me te MCA ki te taapiri epoxy ka puta te nui o te paowa paowa. Ko te whakamahi i te zinc borate hei whakaiti i te kiato o te auahi me te tukunga ka taea, engari me arotau te whakatakotoranga o naianei mo te tauwehenga.
1. Hangaia te whakakore i te auahi o te Zinc Borate
Ko te konutea borate he pehi auahi pai me te whakahiato mura. Kei roto i ona tikanga:
- Whakatairanga Whakatairanga Char: Ka hanga i te paparanga waro matotoru i te wa ngingiha, te wehe i te hāora me te wera, me te whakaiti i te tuku hau mura.
- Aukati auahi: Ka whakakorikori i nga tauhohenga hono-whakawhiti ki te whakaiti i te hanga matūriki auahi, te whakaheke i te kiato auahi (he tino whai hua mo nga polymers penei i te epoxy).
- Pānga Synergistic: Whakarei ake i te mura o te mura ina honoa ki te ūkuikui (hei tauira, konumohe hypophosphite) me te hauota (hei tauira, MCA) nga whakamahana mura.
2. Ko etahi atu, Tāpirihia ranei nga Kaipupuhi auahi
Mo te arotautanga ake o te whakakore i te auahi, whakaarohia nga otinga honohono e whai ake nei:
- Pūhui Molybdenum(hei tauira, zinc molybdate, molybdenum trioxide): He pai ake i te zinc borate engari he utu nui ake; e taunaki ana kia hanumi ki te zinc borate (hei tauira, zinc borate : zinc molybdate = 2:1).
- Konumohe / Konupora Hydroxide: Me nui te utaina (20-40 phr), tera pea ka pa ki nga ahuatanga miihini o te epoxy—kia tupato te whakatika.
3. Nga Whakaritenga Whakaritenga Whakaritea
Ki te whakaaro ko te whakatakotoranga taketakekonumohe hypophosphite + MCA, kei konei nga tohutohu arotautanga (i runga i nga waahanga 100 epoxy resin):
Kōwhiringa 1: Ko te taapiri tika o te Zinc Borate
- Konumohe hypophosphite: Whakaitihia mai i te 20-30 phr ki15-25 ph
- MCA: Whakaitihia mai i te 10-15 haora ki te8-12 ph
- Zinc borate: Tāpiri5-15 ph(Timatahia te whakamatautau i te 10 haora)
- Katoa nga ihirangi aukati mura: Kia mau ki30-40 ph(kaore i te nui o nga moni e pa ana ki te mahi whakapiri).
Kōwhiringa 2: Zinc Borate + Zinc Molybdate Synergy
- Konumohe hypophosphite:15-20 ph
- MCA:5-10 ph
- Zinc borate:8-12 ph
- Konutea molybdate:4-6 ph
- Katoa nga ihirangi aukati mura:30-35 ph.
4. Inenga Whakamana Matua
- Te mura o te mura: UL-94 tahu poutū, whakamātautau LOI (whāngai: V-0 LOI ranei>30%).
- Totote auahi: Whakamahia he kaiwhakamatau kiato auahi (hei tauira, te ruuma auahi NBS) hei whakataurite i te whakahekenga o te Whakatauranga Totote auahi (SDR).
- Nga Taonga Miihini: Me whakarite kia tutuki te kaha tensile me te kaha piri ki nga whakaritenga i muri i te rongoa.
- Te Tukatuka: Whakapumautia te marara rite o nga parenga mura me te kore e pa ki te potata, ki te wa whakaora ranei.
5. Nga whakaaro
- Mana Rahi Matūriki: Whiriwhiria mo te mitanano-rahi konutea borate (hei tauira, te rahi matūriki <1 μm) hei whakapai ake i te marara.
- Whakarereketanga Mata: Whakapaihia te zinc borate me tetahi kaihoko hono silane hei whakarei ake i te hototahi ki te kapia epoxy.
- Whakaritenga Ture: Me whakarite kia tutuki nga mura ahi kua tohua ki te RoHS, REACH, me etahi atu ture.
6. Tauira Hanga (Reference)
| Waehanga | Te rahi (phr) | Mahi |
|---|---|---|
| kapia epoxy | 100 | kapia matrix |
| Konumohe hypophosphite | 18 | Te mura o te mura tuatahi (i runga-P) |
| MCA | 10 | Wāhanga hau-auana mura (N-tau) |
| Zinc borate | 12 | He kaitutei pehi auahi |
| Kai whakaora | Ka rite ki te hiahia | Kua tohua i runga i te punaha |
7. Whakarāpopototanga
- Ko te Zinc borate he whiringa whai hua hei whakaiti i te pahū auahi. Tūtohu tāpiri10-15 phi te whakaiti i te ihirangi konumohe hypophosphite/MCA.
- Mo te pehi auahi atu, hanumi ki nga pūhui molybdenum (hei tauira,4-6 ph).
- Me whai whakamanatanga whakamatautau ki te taurite i te mura o te mura, te aukati auahi, me nga taonga miihini.
