Ka Wehewehena a me ke ʻAno o HTPB
E noʻonoʻo paha ʻoe i ke kumu o ka HTPB kūikawā. ʻO HTPB ke kū nei no ka hydroxyl-terminated polibutadiene. He ʻano kūikawā ko kēia mea e hāʻawi ana iā ia i nā waiwai pono he nui.

Ke hoʻohālikelike ʻoe HTPB (Hydroxyl-terminated polybutadiene CAS 69102-90-5) i nā polyols ʻē aʻe, ʻike ʻoe i nā ʻokoʻa nui i kā lākou hana. Hāʻawi ʻo HTPB iā ʻoe i kahi mahana hoʻololi aniani haʻahaʻa, ʻo ia hoʻi ke kūpaʻa nei kāu mau elastomers i nā kūlana hau. ʻOi aku ka kiʻekiʻe o nā mahana hoʻololi aniani o nā polyols ʻē aʻe, no laila hiki iā lākou ke paʻakikī a palupalu paha ke anu.
ʻIke pū ʻoe i kēlā HTPBʻOi aku ka maikaʻi o ka hoʻopili ʻana o nā elastomers i hoʻokumu ʻia a me ke kūpaʻa kemika. No ka laʻana, loaʻa iā HTPB kahi helu 5B ma ka hoʻāʻo hoʻopili ASTM D3359, ʻoi aku ka kiʻekiʻe ma mua o ka hapa nui o nā polyols ʻē aʻe. ʻO ke ʻano kēia e pipili maikaʻi aʻe kāu mau uhi a i ʻole nā mea hoʻopili a lōʻihi ka lōʻihi.
