Gadzira mhando yakasiyana yeCTBN Carboxyl terminated butadiene nitrile rabha (CTBN) CAS 25265-19-4 Carboxyl-Terminated Butadiene-Acrylonitrile CAS 25265-19-4/68891-46-3
Butadiene acrylonitrile ine liquid carboxyl-terminated butadiene acrylonitrile imhando yerabha ine liquid rab ine carboxyl group se function group yayo, uye code yayo ndeye CTBN, inogona kushandiswa zvakanyanya mundege nenzvimbo dzemaindasitiri. Kazhinji CTBN inoiswa pamwe chete ne somatotype resin. CTBN ine active carboxyl-terminated group inogona kuita pa epoxy resin kuitira kuti iwedzere kuomarara kwayo.
CTBN inogona kushandiswa se:
- Zvinonamira, zvinosunga, zvinovhara, zvinopfapfaidza, zvinoisa muhari (nzvimbo yendege, mota, zvemagetsi/zvemagetsi, zvemaindasitiri, zvemugungwa uye zvekuvaka...)
- Mapendi (mushonga, upfu, mvura inoyerera)
- CTBN yakasimba pa epoxy resin uye ine kushanduka kwakanaka kwekuchinja kwema resins e thermosetting akadai se epoxy, phenolic, unsaturated polyester uye photosensitive resins.
1. Inowedzera kusimba uye kuchinjika kwemaresini ethermoset
2. Inovandudza kunamira kune substrates dzakaoma kubatana nadzo
3. Inowedzera kukanganiswa uye kuramba kutsemuka
4. Inovandudza kugara kwenguva refu (kuramba kuneta)
5. Inowedzera hunhu hwemakanika husingatsvedzi zvakanyanya
6. FDA version inowanikwa
1. CTBN imuchina wakanaka wekugadzirisa maresini ethermosetting akadai se epoxy, phenolic, unsaturated polyester uye maresini anonzwa chiedza. Inogona kuvandudza kusimba kweganda uye kuramba kupwanyika kwechigadzirwa chekupedzisira.
2. Nama yesimbi yakagadzirwa ne epoxy resin iyo inogadziriswa ne CTBN (huwandu hwe acrylonitrile i25%), ine kusimba kwakanaka, kuchinjika uye inodzivirira kuneta. Inogona kushandiswa kubatanidza zvikamu zveplane, pamwe ne organic glass ne terylene belt. Nama iyi inogonawo kushandiswa senama inonamira zvinhu zvakasiyana-siyana zvemachira zvakaita se glass fiber, terylene ne carbon fiber.
3. Namata inogadzirwa kubva kuCTBN uye epoxy resin inogona kugadzika patembiricha yakajairika, inogona kushandiswa kubatanidza zvinhu zvine aluminus, inosvika pakusimba kwakanyanya kwekunamira mushure memaawa makumi manomwe nemaviri. Kusimba kweganda i0.55MPa, uye kusimba kwekucheka i26.7MPa. Chinhu chemagetsi chinovhara chinogadzirwa neCTBN modified epoxy, chinowedzera kuramba kwekupwanyika, hachizove nekutsemuka mushure mekudzokororwa ka200 patembiricha iri pakati pe -55.0℃ kusvika 150℃.
4. CTBN inogona kushandiswa sechinamira mu grind ne cutting wheel, ine mabhenefiti ekuti haina kunamira zvakanyanya asi inodzivirira kukwesha zvakanyanya, pamwe nekushanda zvakanaka kwepolish, kudzivirira mvura inopisa.
5. CTBN inonyanya kushandiswa sechibatiso chezvishandiso zveroketi zvakasimba.
6. CTBN yeCoatings (mushonga, upfu, mvura inoyerera).
7. Uye mamwe marudzi akawanda ekushandiswa
Yakaputirwa mu50kg/dhiramu, 180kg/dhiramu, Nguva yekuchengetera igore rimwe chete.
Mirayiridzo yekuchengetedza:
Kuchengetera kunofanira kunge kuri panzvimbo inotonhorera, yakaoma uye inofefetedza mweya. Mamiriro akanaka ari pakati pe -20 ~ 38℃. Nguva yekuzorora ndeyemwedzi gumi nemiviri, kana yapera, ichiri kushandiswa kana yasvika padanho repamusoro kuburikidza nekuyedzazve. Kana kutakurwa kunofanirwa kudzivirira mvura, chiedza chezuva. Usasanganisa neoxidizer yakasimba.
