Te Whakamahinga o te HTPB i roto i te Whakatō/ te Whakakī i ngā Rauemi Hiko
HTPB (Polibutadiene Kua Whakamutua ki te Hydroxyl), hei elastomer mahi-teitei, ka tukuna he painga ahurei i roto i ngā tono kohua mō ngā rauemi hiko, inā koa i roto i ngā horopaki e hiahia ana ki te ngāwari, te ātete ki te huarere, me te whakamarumaru hiko. Kei raro nei he whakarāpopototanga o ngā kōrero matua e pā ana ki te whakamahinga o HTPB mō te kohua hiko:
**1. Ngā Āhuatanga me ngā Painga o te HTPB mō te Whakatō Kohua**
1. - Ngāwari me te Ātete Pānga: Kia maroke, HTPB ka hanga he elastomer e mimiti ana i te ahotea ā-pūkaha, hei tiaki i ngā wāhanga hiko tairongo (hei tauira, ngā pūoko, ngā papa ara iahiko) mai i te wiri, i te whānui rānei o te wera.
2. - Ārai Hiko: He ātete nui ki te rōrahi (>10¹⁴ Ω·cm), he pai mō te ārai hiko ngaohiko teitei, te tuku tohu auau teitei rānei.
3.- Ātete Matū me te Ātete Huarere: Ātete ki ngā waikawa, ngā kawakore, me ngā hihi UV, he mea tino pai mō ngā taputapu hiko o waho (hei tauira, ngā pouaka hononga PV, ngā hiko motuka).
4.- He iti te whakahekenga o te whakamaroke: Ka whakaiti i te ahotea o roto i muri i te whakatō, ka ārai i te hurihanga o te wāhanga, te ngatata rānei.
5.- Ātete ki te makuku me te puehu: He parenga whai hua ki ngā poke o te taiao.
**2. Hoahoa Hanga Rauemi Whakatō**
- Kōwhiringa Pūnaha Whakaora:
- Ngā Isocyanates (hei tauira, TDI, IPDI): Ka hanga whatunga polyurethane; me whakahaere te ōwehenga NCO/OH (te tikanga 1.05–1.1:1) kia taurite ai te pakeke me te ngāwari.
- Te Whakamaroke i te Peroxide: He pai mō ngā whakamahinga pāmahana teitei engari ka whakaiti pea i te ngāwari.
- Ngā Tāpiri Whakakī:
- Ngā Whakakī Arahi Wera: Boron nitride (he ārai me te arahi wera), alumina (he utu iti).
- Ngā Ārai Mura: He hauwai konumohe, he ārai mura kei roto he ūkuikui hei whakatutuki i ngā paerewa UL94 V-0.
- Ngā mea whakakirikiri: hei tauira, DOA (Dioctyl Adipate) hei whakaiti i te modulus, ahakoa me arotake ngā mōrearea hekenga.
**3. Ngā Whakamahinga Noa**
- Ngā Hikohiko Hōia/Rererangi: Te whakamahi i ngā ara iahiko pere, ngā wāhanga radar, te whakamahi i ngā mea hou HTPBte awhe pāmahana whānui (-50°C ki te 80°C).
- Rāngai Pūngao Hou: Te whakakākahu i te pākahiko lithium, te tiakitanga o te waeine utu, te whakamarumaru taurite me te mimiti ru.
- Taputapu o raro i te wai: He kohua hononga taura raro i te wai, he ātete ki te waikura o te wai tote, ā, he ātete hoki ki te wai.
- Ngā papa hiko tānga (PCB)
- Te Whakawhitiwhiti Kōrero me te Hanganga Whatunga
- Pūngao Whakahou me te Hikohiko Mana
- Ngā Hikohiko Moana
- Ngā Hikohiko Kaihoko Tino-Pai
**4. Ngā Whakaaro mō te Tukanga**
- Tango Mirumiru: Whakakore hau mā te korehau (-0.095 MPa, 10–20 meneti) hei ārai i ngā putunga hau i muri i te whakamaroke.
- Ngā Tikanga Whakamaroke: Mā te whakamahana (60–80°C) ka whakaitihia te wā whakamaroke ki te 4–8 hāora.
- Te Maimoatanga Piripiri i mua: Me whakamahi te maimoatanga plasma, ngā paninga rānei mō ngā papa kore-porowhita (hei tauira, PE) hei whakapakari i te hononga.
**5. Te Whakataurite ki Ētahi Atu Rauemi Whakatō Kohua**
| Taonga | Resin Epoxy | Rapa Hiraka | |
| Te ngāwari | Tino pai (>200% te roa) | Rawakore (pakaru) | Tino pai (>300%) |
| Ātete ki te pāmahana teitei | Te pāmahana waenga (100°C) | Tino pai (150–200°C) | Tino pai (200–250°C) |
| Utu | Waenga | Iti | Teitei |
| Uauatanga o te Tukanga | Waenga (whakahaere haumākū) | Iti | Waenga (whakakorikori konukawata) |
**6. Ngā Rautaki Whakapai**
- Nano-Whakarerekētanga: Te whakauru i te nano-SiO₂ hei whakarei ake i te kaha ā-pūkaha (hei tauira, ka piki ake te kaha kume mai i te 5 MPa ki te 8 MPa).
- Ngā Pūnaha Whakaranu: Te whakakotahitanga-pūhui me te epoxy (hei tauira, EP/HTPB ngā whatunga uru) hei whakataurite i te pakari me te pakari.
HTPB He tino pai ngā rauemi kohua mō te tiaki hiko i roto i ngā taiao hihiri, ā, me arotau ngā hanganga i runga i ngā whakaritenga mahi motuhake.
Kei te tuku tā mātou kamupene HTPB i roto i ngā momo taumata, ā, e whakarato ana i te hanga ritenga i runga i ngā whakaritenga a te kiritaki.
