hoʻomohala i kahi mana like ʻole o CTBN Carboxyl terminated butadiene nitrile rubber (CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 25265-19-4/68891-46-3
ʻO ka wai carboxyl-terminated butadiene acrylonitrile kekahi ʻano o ka laholio wai nona ka hui carboxyl ma ke ʻano he hui hana, a ʻo kāna code ʻo CTBN, hiki ke hoʻohana nui ʻia ma nā wahi mokulele a me nā ʻoihana kīwila. ʻO ka maʻamau, hoʻopili ʻia ʻo CTBN me ka resin somatotype. Hiki i ka CTBN nona ka hui carboxyl-terminated ikaika ke hana ma ka resin epoxy i mea e hoʻonui ai i ka paʻakikī.
Hiki ke hoʻohana ʻia ka CTBN ma ke ʻano he:
- Nā mea hoʻopili, hoʻopaʻa, sila, pīpī, hoʻomoʻa ʻana (aerospace, kaʻa, uila/uila uila, ʻoihana, moana a me nā noi kūkulu hale...)
- Nā uhi (wai hoʻonā, pauka, wai)
- He paʻakikī ka CTBN i ka epoxy resin a he hoʻololi maʻalahi loa ia i nā resins thermosetting e like me ka epoxy, phenolic, unsaturated polyester a me nā resins photosensitive.
1. Hoʻonui i ka paʻakikī a me ka maʻalahi o nā resins thermoset
2. Hoʻomaikaʻi i ka hoʻopili ʻana i nā substrates i paʻakikī ke hoʻopaʻa
3. Hoʻonui i ka hopena a me ke kūpaʻa i ka haki
4. Hoʻomaikaʻi i ke kūpaʻa (pale ʻana i ka luhi)
5. Hoʻonui i nā waiwai mechanical haʻahaʻa haʻahaʻa
6. Loaʻa ka mana FDA
1. He mea hoʻololi maʻalahi maikaʻi loa ʻo CTBN no nā resins thermosetting e like me ka epoxy, phenolic, unsaturated polyester a me nā resins photosensitive. Hiki iā ia ke hoʻomaikaʻi i ke kūpaʻa ʻana i ka brittleness a me ke kūpaʻa ʻana i ka haki ʻana o ka huahana hope loa.
2. ʻO ka mea hoʻopili metala i hana ʻia mai ka resin epoxy i hoʻololi ʻia e CTBN (ʻo ka nui o ka acrylonitrile he 25%), he paʻakikī maikaʻi, maʻalahi a me ke kūpaʻa luhi. Hiki ke hoʻohana ʻia e hoʻopaʻa i nā ʻāpana o ka mokulele, a me ke aniani organik a me ke kāʻei terylene. Hiki ke hoʻohana ʻia kēia mea hoʻopili ma ke ʻano he mea hoʻopili seeping o nā mea lole like ʻole e like me ke aniani fiber, terylene a me ke kalapona fiber.
3. Hiki i ka mea hoʻopili i hana ʻia mai ka CTBN a me ka epoxy resin ke hoʻōla i ka mahana maʻamau, hiki ke hoʻohana ʻia e hoʻopaʻa i nā mea aluminous, e hiki i ka ikaika hoʻopili kiʻekiʻe loa ma hope o 72 mau hola. ʻO ka ikaika peel he 0.55MPa, a ʻo ka ikaika ʻoki he 26.7MPa. ʻO ka mea sila uila i hana ʻia e ka CTBN modified epoxy, ka mea e hoʻoikaika ai i ke kū'ē ʻana i ka haki ʻana, ʻaʻohe haki ma hope o 200 mau manawa hana hou ʻana ma ka mahana ma waena o -55.0℃ a i 150℃.
4. Hiki ke hoʻohana ʻia ka CTBN ma ke ʻano he mea hoʻopili i ka wili a me ka ʻoki ʻana i ka huila, loaʻa iā ia nā pono o ka mea hoʻopili liʻiliʻi akā ʻoi aku ka pale ʻana i ka abrasion, a me ka hana o ka polish maikaʻi, ke kūpaʻa wai wela.
5. Hoʻohana nui ʻia ʻo CTBN ma ke ʻano he mea hoʻopaʻa no nā mea hoʻoulu rocket paʻa.
6. CTBN no nā Uhi (wai hoʻonā, pauka, wai).
7. A me nā ʻano hoʻohana ʻē aʻe he nui
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.
