Zotayidwa carbide

Zotayidwa carbide ndi bayinare zochita kupanga mpweya ndi aluminum pawiri. chilinganizo ake mankhwala monga lemba Al4C3, zikuwoneka ngati wotumbululuka chikasu kapena zofiirira galasi kukhala zovuta structural gululi. Ndi kuzilepheretsa nyamuka kutentha kwa 1400 ° C pa osalimba a 2,36 g / cm³. Monga mbali ya latisi ake maatomu mpweya alipo monga anions apawokha mpweya. pawiri Izi zakonzedwa ndi zimene mwachindunji mpweya ndi aluminum mu Arc ng'anjo, kumakhalanso zazing'ono kuchuluka zosafunika alipo kashiamu carbide chiyambi luso.

Carbide zotayidwa: Makhalidwe ndi tanthauzo

Electrolytic zotayidwa kupanga kumafuna kudzipatula pawiri monga mankhwala dzimbiri mu maelekitirodi graphite. Ngati kumene carbide zotayidwa ndi anachitira ndi madzi kapena kuchepetsa asidi, dziko aumbike. Komanso, pawiri amachitira ndi mpweya ndi wa hydrogen, ndipo mu nkhani ya anachita ndi madzi ndi kumvana hydroxide ndi sodium anapanga mchere zovuta, wotchedwa tetragidroksoalyuminatom methane ndi sodium wochuluka. Mwachibadwa, pawiri ali katundu yeniyeni thupi, amanena kuti ndi akalozera refractive zokhudzana ndi sodium wochuluka D-mzere, nufikira 20 ° C. Pa nthawi yomweyo kuganizira muyezo Gibbs mphamvu ndi muyezo mphamvu zosagwiritsika ntchito mapangidwe, zizindikiro 196 ndi kufikira 88,95Dzh / mol / K. Kukonzekera pawiri zimenezi monga mankhwala mokakamizidwa zosiyanasiyana zovuta mankhwala.

Makamaka, zitsulo masanjidwewo nsanganizo zochokera zotayidwa masanjidwewo ndipo anatsindika ndi carbides zitsulo monga boron carbide ndi pakachitsulo carbide, zimachititsa kuti carbide zotayidwa monga mchitidwe oipa. Zinthu ngati n'zotheka nkhani ya mpweya CHIKWANGWANI, imene adalowa anachita ndi masanjidwewo zotayidwa pa kutentha choposa 500 ° C, komanso amatipatsa cholinga pawiri. Pa ndime ya mankhwala anachita pakati zotayidwa ndi kuponyedwa pakachitsulo carbide wosanjikiza akhoza kukhala carbide aluminiyamu, izo kuphimba pakachitsulo carbide tinthu ndi kuchepetsa mphamvu zakuthupi.

Komabe, zotsatira izi zikhoza kuchepetsedwa ndi wokutira pakachitsulo okusayidi particles abwino kapena preoxidation kukhazikitsa silika ❖ kuyanika. Kudziwa mmene madzi muli tritium, pawiri ndi pansi hydrolysis, chifukwa mu zotayidwa carbide dziko. Pankhaniyi, pawiri ntchito ngati mankhwala reagent mu anachita ndi pawiri inaimitsidwa ndi madzi amapereka tritium ndi dziko. Zotayidwa carbide, omwazika pa masanjidwewo zotayidwa, kumatithandiza kusunga osalimba a chuma, makamaka ngati pamodzi ndi particles wa pakachitsulo carbide.

zipangizo gulu la carbide zotayidwa angathe kupeza kudzera kasakaniza wazitsulo makina zochokera ufa zotayidwa ndi tinthu graphite. Pamodzi ndi pawiri ichi ntchito monga abrasive kwa mkulu-liwiro kudula zipangizo, kuwapatsa kuuma topazi. munda wina wa ntchito ndi pawiri la pyrotechnics, apa timatha kupeza zotsatira za Firefly, zomwe zimachititsa yatsoka kwambiri kwa kukhefula. Onani kuti pa nthawi zosiyanasiyana mu pyrotechnics, iye wakhala ntchito yosiyana kwambiri. Ambiri, pawiri ichi wapeza ntchito lonse makampani mankhwala ndi munda ulimi. Ichi ndi chifukwa makhalidwe mankhwala a carbide zotayidwa, kupereka katundu wake wapadera omwe si khalidwe la mitundu ina ya mankhwala carbide gulu.
