HTPB Whakapūngaohia te Polybutadiene Whakamutua-Rōpū Hydroxyl Whakapūngaohia
Kua whakahauwaihia HTPB Polybutadiene Whakamutua-Rōpū Hydroxyl Whakahauwai
Ngā taipitopito hua:
Ingoa Matū: HTPB Whakahauwai
Momo: Putanga hauwai
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.)
Mō te HTPB kua whakahāngaihia ki te hauwai, he homopolymers kua whakahāngaihia ki te hauwai o te butadiene, he mutunga-rōpū hydroxyl e rua-mutunga, ā, he pai mō te whānuitanga o ngā whakamahinga. Nā te kī o te rōpū 1,2-vinyl, he tino pai te pumau matū o ēnei polibutadienes mō te wā roa.
Ngā Āhuatanga hei:
Hanganga tino ngāwari
Te koretake o te wai
Pūmau iti o te dielectric
He ātete matū pai
Ngā rōpū hydroxyl tauhohe
Te pumau mō te wā roa
Ngā whakarerekētanga kapia, ngā kapia urethane (peita, piripiri, kaihoko paninga), ngā rauemi ārai hiko, ngā elastomers TPU
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.
