Carboxyl-terinated butadiene nitrile (CTBN) polymer is elastomer ine yakanakisa mechaniki, inopisa uye makemikari kuramba. Izvi zvakasiyana zvivakwa zvinoita kuti CTBN ive chinhu chinoshandiswa zvakanyanya mumaindasitiri akasiyana. Muchikamu chino, tichaongorora kuti chii chinonzi carboxyl-terminated butadiene nitrile uye mashandisirwo ayo munzvimbo dzakasiyana.
Carboxyl-yakapera butadiene nitrile is a copolymer yebutadiene uye acrylonitrile iyo inosangana necarboxylation process panguva yekugadzira. Izvi zvinounza mapoka e-carboxyl anoshanda muketani yepolymer, achiwedzera elasticity yayo. Iyo inokonzeresa copolymer ine yakakwira molecular huremu, yakaderera polydispersity index, uye yakanaka solubility mune akasiyana organic solvents.
Carboxyl-terinated butadiene nitrile polymers anozivikanwa nekuramba kwawo kupisa, mafuta, mafuta, hydraulic fluid uye mamwe akawanda makemikari. Kugona kwayo kumira tembiricha yakanyanyisa kubva -40 ° C kusvika 150 ° C, pamwe neakanakisa ozone uye kuramba kwemamiriro ekunze, inoita kuti ive chinhu chakakodzera chekushandisa chinoda.
Imwe yemashandisirwo makuru ecarboxyl-terminated butadiene nitrile iri muindasitiri yezvemuchadenga. Iyo inowanzoshandiswa sechinhu chinoomesera cheepoxy resins inoshandiswa mukugadzirwa kwezvimiro zvinoumbwa nendege. Kuwedzera kweCTBN inovandudza kupikisa kwemaitiro, kusimba kwekutsemuka uye kusimba kwese kweaya macomposites. Kugadzikana kwayo kwekushisa kunobvumira kuchengetedza maitiro ayo emagetsi kunyange pakakwirira uye panguva yekukurumidza kuchinja kwekushisa.
Imwe yakakurumbira kushandiswa kwecarboxyl-terinated butadiene nitrile iri muindasitiri yemotokari. CTBN inowanzoshandiswa sechinhu chakakosha mumachira, zvinonamira uye zvisimbiso zvezvikamu zvemotokari. Iyo yakanakisa mafuta, mafuta uye makemikari kuramba, akasanganiswa nekuchinjika kwayo uye kusimba, inoita kuti ive chinhu chakanakira gaskets, O-mhete, zvisimbiso uye diaphragms. Inobatsira kuve nechokwadi chekushanda kwakakodzera uye hupenyu hurefu hwezvikamu muinjini, kutapurirana uye hydraulic masisitimu.
Indasitiri yemagetsi inobatsirawo kubva kune yakasarudzika zvimiro zvecarboxyl-terinated butadiene nitriles. Iyi elastomer inoshandiswa zvakanyanya mukugadzira tambo yekuvharisa uye sheathing zvinhu. CTBN polymers inopa yakanakisa kuramba hunyoro, mafuta uye makemikari, pamwe neakakwira dielectric simba uye kugadzikana kwemafuta. Zvinhu izvi zvinoita kuti ive chinhu chakanakira kuve nechokwadi chekuchengetedza uye kuvimbika kwemagetsi masisitimu.
Pamusoro pemaindasitiri ataurwa pamusoro apa,carboxyl-yakapera butadiene nitrile inoshandiswawo mukugadzirwa kwependi, adhesives uye sealants, uko kuwirirana kwayo nemhando dzakasiyana-siyana dzemakemikari zvinonyungudutsa zvinonyanya kubatsira. Inoshandiswawo mukugadzirwa kwepamusoro-inoita rubber makomisheni, ichipa yakawedzera kukanganisa kupikisa uye elasticity.
Muchidimbu, carboxybutadiene nitrile ndeye multifunctional elastomer ine yakanakisa mechanical, thermal and chemical resistance. Kuwanda kwayo kwakasiyana-siyana kwekushandisa mune aerospace, mota, magetsi uye mamwe maindasitiri zvakaratidza kuvimbika kwayo uye kushanda kwayo. Sezvo tekinoroji ichifambira mberi uye indasitiri inoda zvekushandisa zvakanyanya, CTBN inoramba ichishanduka uye nekubatsira kune akasiyana maindasitiri, ichiiita chinhu chakakosha chekushandisa kwakawanda.
