CTBN ipolymer inoshanda zvakasiyana-siyana inosanganisa zvinhu zvebutadiene uye acrylonitrile. Inoshandiswa zvakanyanya seanoomesera mu epoxy resins, thermoplastics uye zvimwe zvinhu kuti zviwedzere kusimba kwazvo, kukanganisa kuramba uye kushanduka. Iyi elastomer inowanikwa mumagiredhi akasiyana-siyana ane huremu hwemamorekuru akasiyana uye zviri mukati mecarboxyl kuti ipe zvigadziriso zvakagadziridzwa zvichibva pane zvinodiwa.
Chimwe chezvinhu zvakakosha zveCTBN ndiyo yakanakisa kudzika-tembiricha kuchinjika. Iyo inoramba ichichinjika uye elastic kunyangwe mukutonhora kwakanyanya, ichiita kuti ive yakanakira nzvimbo dzeArctic kana maapplication uko kuratidzwa kune yakaderera tembiricha inotarisirwa. Ichi chivakwa chinovimbisa kuti zvinhu zvine CTBN zvinochengetedza kuvimbika kwavo uye kuita kunyangwe pasi pemamiriro akaomarara.
Pamusoro pezvo, CTBN ine yakanakisa kunamatira kune dzakasiyana siyana zvinhu, zvinosanganisira simbi, mapurasitiki uye macomposites. Iyi inonamira pfuma inoita kuti ive yekuwedzera yakakosha mumachira, zvinonamira uye zvisimbiso, inovandudza chisungo chavo uye hupenyu hwebasa. Kuenderana kweCTBN nemhando dzakasiyana-siyana dzezvinhu zvinowedzera kubatsira kwayo mumaindasitiri akasiyana.
Pamusoro pezvo, CTBN inozivikanwa nekunaka kwayo kupikisa. Inotora uye inoparadzira simba rekukanganisa, kudzivirira zvinhu kubva pakuputika nekupwanya. Ichi chivakwa chakanyanya kukosha mukushandisa uko kukanganisa uye kukanganisa kuramba kwakakosha, senge aerospace, mota, uye zvemitambo. Nekubatanidza CTBN mune izvi zvinhu, vagadziri vanogona kuve nechokwadi chekuti zvigadzirwa zvavo zvinokwanisa kumira sevhisi yakaoma.
Imwe nzvimbo apoCTBN excels iri mukupa kuomarara uye elasticity kune akaomarara mapolymer. Nekusanganisa CTBN ne thermoset polymers senge epoxy resins, macomposites anozobuda anoratidza kusimba kwakawedzera uye kuramba kutsemuka. Ichi chivakwa chinobatsira zvakanyanya mukugadzira zvinhu zvakaita semichina inorema, zvimiro zvemukati uye magetsi insulators.
Iyo yakasarudzika musanganiswa wezvivakwa zvinopihwa neCTBN inoita kuti ive yakakosha zvinhu mumhando dzakasiyana siyana. Mainjiniya emuchadenga anoshandisa CTBN yezvisimbiso elastomeric, gaskets uye vibration-damping components. Muindasitiri yemotokari, CTBN inoshandiswa mukubata zvinobatisa, underbody coatings uye mafuta system zvikamu.CTBNinoshandiswawo zvakanyanya mukugadzirwa kwezvinhu zvemitambo zvemhando yepamusoro, zvinosanganisira mabhora egorofu, tsvimbo dzehockey uye shangu dzemitambo.
Muchidimbu, CTBN (carboxyl-terminated butadiene acrylonitrile) iine versatile elastomer iyo inowedzera zvinhu zvenyama. Iine yakanakisa kudzika-tembiricha kuchinjika, kunamatira, kukanganisa kupikisa uye kuoma, CTBN inoshandiswa zvakanyanya mumaindasitiri akadai seaerospace, mota nemitambo. Sezvo tekinoroji ichifambira mberi uye kudiwa kwezvinhu zvekushanda kwepamusoro kunowedzera, CTBN ingangoramba ichiita basa rakakosha mukuvandudza kuvimbika uye kusimba kwezvakasiyana zvigadzirwa.
Isu tiri mutengesi wepamusoro weCTBN muChina, tinopa akasiyana mavhezheni eCTBN uye zvimwe zvinhu zvine hukama senge.HTPB,ATBN,ATPB , nezvimwewo. Zvichakadaro isu tinogona kutsvagisa nekugadzira iyo CTBN nyowani maererano nezvinodiwa zvakakosha zvevatengi vedu. Heano mamwe mamakisi edu eCTBN, kune zvimwe ndapota taura kuburikidzainfo@theoremchem.com
