CTPB cas 586976-24-1 Carboxyl-Terminated Polybutadiene CTPB
ʻO ka Carboxyl-terminated liquid polibutadiene rubber i kapa ʻia ʻo CTPB no ka pōkole. No ka mea aia nā carboxyl ma nā wēlau ʻelua o ka mole polymeric, ke hoʻomau nei kēia polymer i ka hoʻonohonoho ʻana ma ke ʻano o ka hui carboxyl, ua maʻemaʻe ka hoʻolaha ʻana o ka pūnaewele a me ka ʻole o kahi terminal manuahi. no laila he hana mechanical maikaʻi loa.
Hiki i nā hui hopena carboxyl ke hana me ka resin epoxy, kahi hopena paʻakikī maikaʻi ma ka resin epoxy. Ke hoʻohālikelike ʻia me CTBN, ʻoi aku ka haʻahaʻa o ka viscosity o CTPB, ʻoi aku ka maikaʻi o ka hana haʻahaʻa haʻahaʻa a me ka maʻalahi.
ʻAʻole hiki ke hoʻohana wale ʻia ka huahana i ka propellant rocket paʻa, akā hiki ke hoʻohana ʻia i nā elastomers, adhesives, sealing material, epoxy resin modification a me nā mea pale uila.
Hoʻopaʻa ʻia i loko o 50kg/pahu, 180kg/pahu, ʻO ka manawa mālama he 1 makahiki.
Nā kuhikuhi palekana:
Pono e mālama ʻia ma kahi anuanu, maloʻo a me ka ea. ʻO ke kūlana maikaʻi loa ma waena o -20 ~ 38℃. ʻO ke ola o ka papa he 12 mau mahina, inā pau, e hoʻohana mau ʻia inā kū i ke kūlana ma o ka hoʻāʻo hou ʻana. I ka wā e lawe ai, pono e pale i ka ua a me ka lā. Mai hoʻohuihui me ka oxidizer ikaika.
