CTPB Carboxyl-terminated polybutadiene(CTPB) CAS 586976-24-1
He ʻano wai polibutadiene ka CTPB me nā hui carboxyl ma nā wēlau ʻelua o ka molekala, nona ke kūpaʻa anu a me ka elasticity 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.
Hoʻohana nui ʻia ka CTPB ma ke ʻano he mea hoʻoikaika no nā mea hoʻopili a me nā mea hoʻopaʻa epoxy resin, hiki ke hoʻohana ʻokoʻa ʻia no ka hana ʻana i nā mea sila, nā mea hoʻopili, nā uhi, nā olonā elastic, a me nā mea hana i ka ʻili, nā mea hoʻololi rubber, a pēlā aku.
Ma ke ʻano he mea hoʻoulu
Hoʻopaʻa ʻia i loko o 50kg/pahu, 170kg/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.
