CTPB Carboxyl-terminated polybutadiene(CTPB) CAS 586976-24-1
He rapa polibutadiene wai te CTPB, kei ngā pito e rua o te ngota ngā rōpū carboxyl, ā, he tino pai te ātete ki te makariri me te ngāwari.
Ka taea e ngā rōpū pito carboxyl te tauhohe ki te kapia epoxy, he pānga pakari pai ki te kapia epoxy. Ki te whakatauritea ki te CTBN, he iti ake te matotoru o te CTPB, he pai ake te mahi pāmahana iti me te ngāwari.
Ko te CTPB e whakamahia whānuitia ana hei whakakaha i ngā piripiri me ngā hiri o te kapia epoxy, ā, ka taea hoki te whakamahi motuhake mō te hanga rauemi hiri, piripiri, paninga, muka rapa me ngā rauemi horihori pērā i te hiako, te rapa whakarerekē, me ētahi atu.
Hei pūwero
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.
