Kodi carboxyl-terminated butadiene nitrile imagwiritsidwa ntchito bwanji?

Carboxyl-terminated butadiene nitrile (CTBN) polima ndi elastomer yokhala ndi makina abwino kwambiri, kutenthetsa komanso kukana mankhwala. Zinthu zapaderazi zimapangitsa CTBN kukhala yogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. M'nkhaniyi, tiwona kuti carboxyl-terminated butadiene nitrile ndi chiyani komanso ntchito zake m'magawo osiyanasiyana.

 Carboxyl-kuthetsedwa butadiene nitrile ndi copolymer ya butadiene ndi acrylonitrile yomwe imalowa mu carboxylation panthawi yopanga. Izi zimabweretsa magulu ogwirira ntchito a carboxyl mu unyolo wa polima, kukulitsa mphamvu zake zotanuka. Copolymer yomwe imachokera imakhala ndi kulemera kwakukulu kwa maselo, index yotsika ya polydispersity, komanso kusungunuka kwabwino muzosungunulira zosiyanasiyana.

Carboxyl-terminated butadiene nitrile polima amadziwika chifukwa chokana kutentha, mafuta, mafuta, madzi amadzimadzi ndi mankhwala ena ambiri. Kutha kupirira kutentha kwambiri kuchokera -40 ° C mpaka 150 ° C, kuphatikiza ndi ozoni wake wabwino kwambiri komanso kukana kwanyengo, kumapangitsa kuti ikhale chinthu chofunikira kwambiri pakufunsira ntchito.

Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi carboxyl-terminated butadiene nitrile ndi ntchito yazamlengalenga. Nthawi zambiri amagwiritsidwa ntchito ngati chothandizira cholimba cha ma epoxy resins omwe amagwiritsidwa ntchito popanga zida zamagulu a ndege. Kuwonjezera kwaMtengo CTBN  imathandizira kukana kukhudzidwa, kulimba kwa fracture ndi kulimba kwathunthu kwa zophatikizika izi. Kukhazikika kwake kwa kutentha kumapangitsa kuti ikhalebe ndi makina ake ngakhale pamtunda wapamwamba komanso pakusintha kutentha kwachangu.

Kugwiritsiridwa ntchito kwina kodziwika kwa carboxyl-terminated butadiene nitrile kuli m'makampani amagalimoto. CTBN imagwiritsidwa ntchito nthawi zambiri ngati chinthu chofunikira kwambiri pakupangira zokutira, zomatira ndi zosindikizira pamagalimoto. Mafuta ake abwino kwambiri, mafuta ndi kukana kwa mankhwala, kuphatikizapo kusinthasintha kwake ndi kukhazikika kwake, kumapangitsa kukhala chinthu choyenera kwa ma gaskets, O-rings, zisindikizo ndi diaphragms. Imathandiza kuonetsetsa kuti magwiridwe antchito ndi moyo wautali wazinthu zamainjini, ma transmissions ndi ma hydraulic systems.

Makampani opanga zamagetsi amapindulanso ndi zinthu zapadera za carboxyl-terminated butadiene nitriles. Elastomer iyi imagwiritsidwa ntchito kwambiri popanga kutchinjiriza kwa chingwe ndi zida za sheathing. Ma polima a CTBN amapereka kukana kwambiri chinyezi, mafuta ndi mankhwala, komanso mphamvu ya dielectric yayikulu komanso kukhazikika kwamafuta. Zinthuzi zimapangitsa kuti zikhale zofunikira kwambiri kuti zitsimikizire chitetezo ndi kudalirika kwa machitidwe a magetsi.

Kuphatikiza pa mafakitale omwe tawatchulawa,carboxyl-terminated butadiene nitrile amagwiritsidwanso ntchito popanga utoto, zomatira ndi zosindikizira, komwe kumagwirizana ndi mitundu yosiyanasiyana ya zosungunulira za organic kumakhala kopindulitsa kwambiri. Amagwiritsidwanso ntchito popanga mankhwala opangira mphira apamwamba kwambiri, omwe amapereka kukana kwamphamvu komanso kukhazikika.

Mwachidule, carboxybutadiene nitrile ndi multifunctional elastomer yokhala ndi makina abwino kwambiri, kutentha komanso kukana mankhwala. Ntchito zake zambiri muzamlengalenga, zamagalimoto, zamagetsi ndi mafakitale ena zatsimikizira kudalirika kwake komanso kuchita bwino. Popeza kupita patsogolo kwaukadaulo komanso mafakitale kumafuna zida zapamwamba zogwirira ntchito, CTBN ikupitilizabe kusinthika ndikuthandizira m'mafakitale osiyanasiyana, ndikupangitsa kuti ikhale yofunikira pazogwiritsa ntchito zambiri.
