Polymer nke Carboxyl-endated butadiene nitrile (CTBN) bụ elastomer nwere ezigbo iguzogide igwe, okpomọkụ na kemịkalụ. Njirimara pụrụ iche ndị a na-eme ka CTBN bụrụ ihe a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche. N'isiokwu a, anyị ga-enyocha ihe Carboxyl-endated butadiene nitrile bụ na ojiji ya n'ọtụtụ ọrụ dị iche iche.
butadiene nitrile nke a kwụsịrị na carboxylbụ copolymer nke butadiene na acrylonitrile nke na-eme usoro carboxylation n'oge mmepụta. Usoro a na-ewebata otu ọrụ carboxyl n'ime agbụ polymer, na-eme ka ikike ya dịkwuo mma. Copolymer nke na-esi na ya apụta nwere oke ibu molekul dị elu, obere polydispersity index, na ezigbo mgbaze na ihe mgbaze dị iche iche nke organic.
A maara polima butadiene nitrile nke Carboxyl kwụsịrị maka iguzogide okpomọkụ, mmanụ, mmanụ ọkụ, mmiri mmiri hydraulic na ọtụtụ kemịkalụ ndị ọzọ dị mma. Ike ya iguzogide okpomọkụ dị oke njọ site na -40°C ruo 150°C, yana ozone ya dị mma na iguzogide ihu igwe, na-eme ka ọ bụrụ ihe kacha mma maka ojiji siri ike.
Otu n'ime ojiji dị mkpa nke butadiene nitrile nke carboxy na-akwụsị bụ n'ime ụlọ ọrụ ụgbọelu. A na-ejikarị ya eme ihe dị ka ihe na-eme ka ọ sie ike maka resin epoxy nke e ji eme ihe n'imepụta ihe owuwu ụgbọelu. CTBN na-eme ka iguzogide mmetụta, ike mgbawa na ogologo oge nke ihe ndị a dị n'ime ya ka mma. Nkwụsi ike okpomọkụ ya na-enye ya ohere ịnọgide na-enwe ihe onwunwe ya ọbụlagodi n'ebe dị elu na n'oge mgbanwe okpomọkụ ngwa ngwa.
Ngwa ọzọ a ma ama nke butadiene nitrile nke carboxyl kwụsịrị bụ n'ụlọ ọrụ ụgbọ ala. A na-ejikarị CTBN eme ihe dị ka ihe dị mkpa na mkpuchi, ihe nrapado na ihe mkpuchi maka akụkụ ụgbọ ala. Mmanụ ya, mmanụ ọkụ na kemịkalụ dị mma, yana mgbanwe ya na ogologo oge ya, na-eme ka ọ bụrụ ihe kacha mma maka gaskets, mgbanaka O, akara na diaphragms. Ọ na-enyere aka hụ na akụrụngwa dị na injin, nnyefe na sistemụ hydraulic na-arụ ọrụ nke ọma na ogologo oge.
Ụlọ ọrụ eletriki na-eritekwa uru site na njirimara pụrụ iche nke nitriles butadiene nke carboxyl kwụsịrị. A na-eji elastomer a eme ihe nke ukwuu n'imepụta ihe mkpuchi waya na ihe mkpuchi. Polymer CTBN na-enye ezigbo iguzogide mmiri, mmanụ na kemịkalụ, yana ike dielectric dị elu na nkwụsi ike okpomọkụ. Njirimara ndị a na-eme ka ọ bụrụ ihe zuru oke maka ijide n'aka na sistemụ eletriki dị nchebe na ntụkwasị obi.
Na mgbakwunye na ụlọ ọrụ ndị a kpọtụrụ aha n'elu, butadiene nitrile nke a kwụsịrị na carboxylA na-ejikwa ya eme ihe n'imepụta agba, ihe mmado na ihe mkpuchi, ebe ndakọrịta ya na ọtụtụ ihe mgbaze organic bara uru karịsịa. A na-ejikwa ya eme ihe n'ịmepụta ihe ndị nwere rọba dị elu, na-enye mmụba iguzogide mmetụta na njupụta.
Na nchịkọta, carboxybutadiene nitrile bụ elastomer nwere ọtụtụ ọrụ, nke nwere ezigbo iguzogide igwe, okpomọkụ na kemịkalụ. Ọtụtụ ọrụ ya na mbara igwe, ụgbọ ala, eletriki na ụlọ ọrụ ndị ọzọ egosila na ọ bụ ihe a pụrụ ịtụkwasị obi na irè. Ka teknụzụ na-aga n'ihu ma ụlọ ọrụ na-achọ ihe arụmọrụ ka mma, CTBN na-aga n'ihu na-agbanwe ma na-enye aka na ụlọ ọrụ dị iche iche, na-eme ka ọ bụrụ ihe bara uru maka ọtụtụ ngwa.
