Tātai：
Pūāhua: Kaituku Whakamanahia o Haina / Raihana kaweake HTPB
Paerewa: GB (Paerewa Ā-iwi) / GJB (Paerewa Hōia/ GJB 1327A-2003)
He pūhui wai maikuku mamao te HTPB, te rapa wai hou. He rerekē ngā āhuatanga nā te mea he ranunga te HTPB, ehara i te matū parakore, ā, he mea hanga kia tutuki ai ngā whakaritenga motuhake a ngā kiritaki. Ko te HTPB noa ko te R-45M me ia pito o te mekameka e mutu ana ki te rōpū hydroxyl [OH]. PS: ka taea e mātou te hanga i tētahi putanga o te HTPB e ai ki ngā tono a ngā kiritaki, me te hoahoa hou i te HTPB me te mekameka kotahi o te hydroxyl -OH. I taua wā, ka taea e mātou te hanga hauwai i te HTPB.)
Ka taea e te kaihopu toronga mekameka, te kaihopu honohono i roto i te pāmahana rūma, i te tauhohenga pāmahana teitei rānei te whakaputa i te hanganga whatunga 3D o te ihirangi whakaora. He tino pai ngā āhuatanga miihini o te ihirangi whakaora, he ātete pai ki te waikura, he ātete waikawa me te kawakore, he ātete kakahu, he ātete pāmahana iti me te whakamarumaru hiko pai.
Ka taea te hanga i ngā polyurethane i hangaia mai i te HTPB mō ngā āhuatanga ā-tinana motuhake; ka taea e ngā polyurethane te tino pīngore, te pakari, me te mārō. Ko ētahi o ngā hua ko: ngā panera whakamahana pahuka mārō; ngā wira me ngā potae elastomeric pakari (e whakamahia ana mō ngā papa reti, ngā arawhata, ngā papa reti, me ētahi atu); ngā pū whakatārewatanga motuka; ngā matū whakakī hiko; ngā piripiri mahi-teitei; ngā paninga mata me ngā hiri mata; ngā muka hangai (hei tauira, Spandex); te whāriki papa raro; ngā wāhanga kirihou mārō (hei tauira, mō ngā taputapu hiko).
Ko tētahi whakamahinga nui o te HTPB kei roto i te pūwero rōkete totoka. Ka herea e ia te matū whakahāngai, te wahie me ētahi atu kai hei papatipu totoka engari he ngāwari i roto i te nuinga o ngā pūnaha pūwero hiato. Ka mahi te polyurethane kua rongoatia hei wahie i roto i aua ranunga. Hei tauira, ko te pūwero he "HTPB/AP/Al=12/68/20", ko te tikanga, i whakaritea e te papatipu, HTPB me te 12% whakaora (te here me te wahie), te ammonium perchlorate 68% (te whakahāngai), me te paura konumohe 20% (te wahie).
Ko ngā pūwero rite, e mōhiotia whānuitia ana ko te APCP (pūwero whakakotahi ammonium perchlorate) e whakamahia ana i roto i ngā tauira rōkete nunui. E 2–3 ngā wā ka puta i te APCP noa te kaha motuhake o te pūwero paura pango e whakamahia ana i roto i te nuinga o ngā motuka rōkete iti.
Ka whakamahia hoki te HTPB hei wahie rōkete ranu.
Ko ngā āhuatanga mahi o te HTPB e whai ake nei:
1. Te koretake o te wai
2. Ngā rōpū hyroxyl tauhohe
3. Te pāmahana whakawhiti karāhe iti
4. Tae iti - wai matotoru mārama teitei
5. Ātete ki te waikura
6. Ātete pāmahana iti
7. He iti te uruhanga o te makuku
8. Ātete ki ngā waikawa me ngā kawakore wai
9. Ātete kaha ki te kakahu
10. He piri pai ki ngā momo papa
11. Ngā āhuatanga ārai hiko
Ka taea te whakamahi i te HTPB i roto i:
- Ngā paninga
- Ngā piripiri
- Pūwero
- Polyurethane (PU)ngā elastomer
- Ngā Here
- Ngā hiri
- Ngā rauemi ārai hiko
- Ngā hua rapa
- Ngā rauemi hanganga i roto i ngā motuka me ngā waka rererangi
- Ngā rauemi hanga whare(ātete wai, ārai waikura, ārai wera)
- Te whakatō me te whakakī i te ipu
- Whakarerekētanga Pūmua
- me te tini ētahi atu ngā momo whakamahinga.
Te tākai:
I tākaihia ki te 50kg/pahu, 170kg/pahu, Ko te wā rokiroki he 1 tau.
Ngā tohutohu haumaru:
Me penapena ki te wāhi matao, maroke, ā, me te hauhautanga. Ko te pāmahana pai rawa atu kei waenganui i te -20 ~ 38℃. E 12 marama te roa o te rokiroki, ki te pau te wā, ka whakamahia tonu mēnā kua tutuki i te paerewa mā te whakamātautau anō. Me karo i te ua, i te rā rānei i te wā e kawe ana. Kaua e whakaranua ki te waikura kaha.
