Kodi butadiene nitrile yomwe imachotsedwa ndi carboxyl imagwiritsidwa ntchito pa chiyani?

Polima ya Carboxyl-terminated butadiene nitrile (CTBN) ndi elastomer yokhala ndi mphamvu yabwino kwambiri yolimbana ndi makina, kutentha komanso mankhwala. Makhalidwe apaderawa amapangitsa CTBN kukhala chinthu chogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. M'nkhaniyi, tifufuza zomwe carboxyl-terminated butadiene nitrile ndi momwe imagwirira ntchito m'magawo osiyanasiyana.

 Nitrile ya butadiene yochotsedwa ndi carboxylndi copolymer ya butadiene ndi acrylonitrile yomwe imadutsa mu njira ya carboxylation panthawi yopanga. Njirayi imayambitsa magulu ogwira ntchito a carboxyl mu unyolo wa polima, ndikuwonjezera mphamvu zake zotanuka. Copolymer yomwe imachokera imakhala ndi kulemera kwakukulu kwa mamolekyulu, kuchuluka kochepa kwa polydispersity, komanso kusungunuka bwino mu zosungunulira zosiyanasiyana zachilengedwe.

Ma polima a butadiene nitrile omwe amachotsedwa ndi carboxyl amadziwika kuti ndi olimba kwambiri ku kutentha, mafuta, mafuta, madzi amadzimadzi ndi mankhwala ena ambiri. Kutha kwake kupirira kutentha kwambiri kuyambira -40°C mpaka 150°C, kuphatikiza ndi ozone yake yabwino komanso kukana nyengo, kumapangitsa kuti ikhale chinthu chabwino kwambiri chogwiritsidwa ntchito molimbika.

Chimodzi mwa zinthu zazikulu zomwe zimagwiritsidwa ntchito kwambiri ndi butadiene nitrile yomwe imachotsedwa ndi carboxyl ndi mumakampani opanga ndege. Nthawi zambiri imagwiritsidwa ntchito ngati chomangira cha epoxy resins chomwe chimagwiritsidwa ntchito popanga zinthu zopangidwa ndi ndege. CTBN Zimathandiza kuti zinthuzi zisamavutike kugwedezeka, kulimba kwa ming'alu komanso kulimba kwa zinthuzi. Kukhazikika kwa kutentha kwake kumathandiza kuti zisunge mphamvu zake ngakhale pamalo okwera komanso kutentha kukasintha kwambiri.

Ntchito ina yodziwika bwino ya butadiene nitrile yomwe imachotsedwa ndi carboxyl ndi mumakampani opanga magalimoto. CTBN imagwiritsidwa ntchito kwambiri ngati chopangira chofunikira kwambiri pakuphimba, zomatira ndi zomatira pazida zamagalimoto. Kukana kwake mafuta, mafuta ndi mankhwala, kuphatikiza kusinthasintha kwake komanso kulimba kwake, kumapangitsa kuti ikhale chinthu chabwino kwambiri chopangira ma gasket, ma O-rings, zisindikizo ndi ma diaphragm. Imathandiza kuonetsetsa kuti zigawo za injini, ma transmissions ndi ma hydraulic system zikugwira ntchito bwino komanso kukhala ndi moyo wautali.

Makampani opanga magetsi amapindulanso ndi zinthu zapadera za butadiene nitriles zomwe zimachotsedwa ndi carboxyl. Elastomer iyi imagwiritsidwa ntchito kwambiri popanga zinthu zoteteza mawaya ndi zokutira. Ma polima a CTBN amapereka kukana bwino chinyezi, mafuta ndi mankhwala, komanso mphamvu ya dielectric yambiri komanso kukhazikika kwa kutentha. Zinthu zimenezi zimapangitsa kuti ikhale chinthu chabwino kwambiri chotsimikizira chitetezo ndi kudalirika kwa makina amagetsi.

Kuwonjezera pa mafakitale omwe atchulidwa pamwambapa, butadiene nitrile yochotsedwa ndi carboxylimagwiritsidwanso ntchito popanga utoto, zomatira ndi zotsekera, komwe kugwirizana kwake ndi mitundu yosiyanasiyana ya zosungunulira zachilengedwe kuli kopindulitsa kwambiri. Imagwiritsidwanso ntchito popanga mankhwala a rabara ogwira ntchito kwambiri, zomwe zimapangitsa kuti ikhale yolimba komanso yolimba.

Mwachidule, carboxybutadiene nitrile ndi elastomer yogwira ntchito zambiri yokhala ndi kukana kwabwino kwa makina, kutentha ndi mankhwala. Ntchito zake zosiyanasiyana m'mafakitale a ndege, magalimoto, zamagetsi ndi mafakitale ena zatsimikizira kudalirika kwake komanso kugwira ntchito bwino. Pamene ukadaulo ukupita patsogolo komanso mafakitale akufuna zipangizo zogwirira ntchito bwino, CTBN ikupitilizabe kusintha ndikuthandizira m'mafakitale osiyanasiyana, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri pa ntchito zambiri.
