Hanganga Matū me ngā Āhuatanga o HTPB E pā ana ki ngā piripiri
Ka taea e koe te mārama ki te mana o HTPB mā te titiro ki tōna hanganga matū. He tūāpapa raina te nuinga o tēnei pūmua, engari ka kitea anō hoki ētahi manga. Mā tēnei hanganga ka taurite te āhua i waenga i ngā āhuatanga kirihou wera me te tūāpapa wera. Mā te tūāpapa ka āwhina i ngā piri kia mau tonu te kaha me te ngāwari. He tino iti te pāmahana whakawhiti karāhe a te HTPB, tata ki te -75°C. Ko te tikanga ka mau tonu te ngāwari o tō piri, ahakoa i roto i ngā āhuatanga hukapapa. Ko ngā pito o te HTPB He rōpū hydroxyl ngā mekameka. He tino tauhohe ēnei rōpū, ā, ka āwhina ki te hanga hononga matū kaha. Ka whiwhi hoki koe i te tuara hydrophobic, arā, kāore e ngāwari te pakaru o te piripiri e te wai. Ko te taumaha ngota o HTPB ka pā ki te kaha me te ngāwari o tō piripiri. Ina whakamahia e koe HTPB Ki te nui ake te taumaha ngota, ka nui ake te kaha me te ngāwari. Ko te maha o ngā rōpū hydroxyl, tata ki te 2.4 ki te 2.6 mō ia mekameka, e whakahaere ana i te nui o te hononga whakawhiti. Ko te tikanga o te nui ake o te hononga whakawhiti he roa ake te mau me te mahi.
Tohutohu: Ka taea e koe te whiriwhiri i ngā momo HTPB rerekē hei whakatutuki i ngā hiahia o tō piripiri. Mā ngā momo matotoru iti ka māmā ake te whakaranu me te hora, engari mā ngā momo matotoru teitei ka kaha ake.

Ngā Tikanga mō te Whakauru HTPBNgā Āhua Whakaora, Ngā Tauwehenga, me te Tukatuka
Me āta whai koe i ngā mahi ina tāpirihia te HTPB ki te piripiri. Tīmata mā te whakaranu i te HTPB ki te plasticizer me te catalyst. Whakamahia he ranunga planetary, he ranunga sigma-blade rānei i te 60°C pea. Tāpirihia ētahi atu kai, pērā i te ammonium perchlorate, te konumohe rānei, mārire mō ngā haora e rua ki te whā i raro i te korehau. Whai muri i te whakaranu, tāpirihia he matū whakaora, pērā i te isophorone diisocyanate (IPDI), i te 50–60°C. Whakaranua mō te 15–30 meneti. Kātahi, makahia te ranunga ki roto i ngā pokepokea ai, ka whakamaroke i te 60°C mō ngā rā e rima ki te whitu. Mō ngā hua pai rawa atu, puritia te piripiri ki te 50°C mō tētahi atu wiki, e rua rānei.
