Faifi tambala (Ni) - ndi chinthu mankhwala kwa nthawi dongosolo la Mendeleev, zomwe zili m'gulu la wa ku Fe, Co, Ni. Faifi tambala ndi zitsulo za mtundu woyera ndi noticeable silvery Sheen. Izo zimapita bwino ndi zitsulo zina kupanga kasakaniza wazitsulo nthawi yomweyo.

Kupezeka kwa faifi tambala

faifi tambala miyala anali woyamba anatulukira ndi sayansi ku Sweden A. Cronstedt mu 1751. Kale Anthuwa ake oyambirira ku miyala Saxony ankadziwa bwino kuti kunja ankawoneka ngati mkuwa ndi. Ndi ntchito kupangira mankhwala steklovarami wobiriwira. Nthawi zambiri steelmakers nthawi kuti kuyesayesa kutuluka aloyi izi zamkuwa, koma zoyesayesa zawo zonse zalephera. Choncho, kumapeto kwa zaka za m'ma XVII. Faifi tambala zitsulo nalo dzina lake loyamba - ". Mdierekezi miyala" "kupfernikel" omwe anamasuliridwa njira Mineralogist Cronstedt akadali anakwanitsa kutenga okusayidi wobiriwira, ndipo ndi kuchepetsa yamasika chinapezeka mwa faifi tambala yokha.

atafufuza zitsulo chinkhoswe wasayansi Bergman. Kulandira mu maonekedwe ake angwiro, ndi kupeza kuti katundu wa faifi tambala pafupi ndi makhalidwe a chitsulo. Mwatsatanetsatane, zitsulo izi kuphunzira ndi ofufuza ena, kuyambira Proust. Pang'onopang'ono akaone katundu osiyanasiyana, kuphatikizapo kachulukidwe wa faifi tambala. Ndipotu, mawu akuti "Nikkel" ndi zauve mawu Anthuwa. Imachokera ndi olakwika Niccolaus natumikira dzina duplicitous, anthu achinyengo. Tanthauzo lachiwiri la Mau anali "mzimu wopulupudza," "slacker."

faifi tambala kachulukidwe ndi zina

Faifi tambala ali katundu monga ductility ndi malleability. zizindikiro zimenezi kophweka poyera malipiro ake. Kuyambira analandira mapepala zitsulo ndi machubu. Faifi tambala - m'malo cholimba zakuthupi. mphamvu kwamakokedwe ndi 450 MPa. Choncho vysokoplastichen, komanso ali mkulu dzimbiri kukana. The madutsidwe matenthedwe wa faifi tambala ndi 90,1 W / (m · K) (pa 25 ° C).

Ncho ores kumaphatikizapo isotopes asanu khola. Faifi tambala zimagawidwa monga zitsulo. Faifi tambala kachulukidwe ndi 8902 makilogalamu / mamita ^3. Ndi kawiri kuposa titaniyamu, koma phindu lake n'zosangalatsa kumva ndi wofanana ndi osalimba zamkuwa.

Kodi faifi tambala dzimbiri anaphimba?

Faifi tambala kugonjetsedwa ndi kutentha. Ngati zitsulo ichi ntchito m'malo mafakitale, nthawi zambiri yokutidwa ndi okusayidi film, ndi pang'ono kumathima. Nawonso si ataphimbidwa ndi dzimbiri. Sachita izo, ndi asidi - kaya organic kapena zochita kupanga. Dzimbiri sifikira zitsulo izi ngakhale mowa otentha. Choncho, faifi tambala kawirikawiri amagwiritsidwa ntchito makampani chakudya.

Kodi faifi tambala zikhoza kukhala dzimbiri?

Okwana pali ena mapangidwe kumene zitsulo akhoza anawonongedwa. Choyamba, ndi nyanja madzi. Ndiponso, zoipa amakhudza zamchere hypochlorite njira. Sulfa kumachititsanso dzimbiri, njira mchere, madzi ammonia.

kasakaniza wazitsulo faifi tambala

zitsulo Izi ndi zowonjezera zabwino zitsulo. Izo kumawonjezera ductility ake ndi mphamvu. Kuwonjezera faifi tambala ndi chromium kasakaniza wazitsulo kupereka mkulu dzimbiri kulimbikira steels. Chimagwiritsidwa ntchito mu makampani chromium-faifi tambala zitsulo zosapanga dzimbiri, zimene kukhala ndi mkulu mlingo wa thermostability.

umagwirira A odziwika kasakaniza wazitsulo kumene faifi tambala ndi mbali yaikulu. Kachulukidwe faifi tambala amalola ntchito zake kasakaniza wazitsulo ndi chitsulo, zotayidwa, manganese, chromium ndi pakachitsulo. kasakaniza wazitsulo oterowo ntchito polenga heaters. Iwo ndi mkulu mlingo wa permeability maginito. Ntchito chitsulo chosungunula zomangamanga, imene faifi tambala anawonjezera. Industrial yopanga zitsulo anayamba pafupifupi zaka zana zapitazo. Pafupifupi 80% ya faifi tambala ntchito yopangira zitsulo ndi faifi tambala kasakaniza wazitsulo.

zina za ntchito zitsulo

Faifi tambala ndi kasakaniza wazitsulo ake ntchito osati kwa kupanga zosapanga steels. Zitsulo ndi kasakaniza wazitsulo ntchito ndi sachita polenga zida mankhwala, shipbuilding. Nichrome ndi chromel ndi zinthu constituent za magetsi banja: toasters, zitsulo, ndi heaters danga. kasakaniza wazitsulo Other ntchito yomanga ziwiya panyanja. Faifi tambala zokutira kawirikawiri kukongoletsa.

zitsulo kawopsedwe

The wambirimbiri faifi tambala mwina mavuto pa thupi. Kuchuluka wokhutira chakudya akhoza kukamba za kuwopsyeza mwachindunji thanzi. Zotsatira zambiri zokhudzana kwambiri ndi thupi faifi tambala - izo ndi ziwengo. komanso amayambitsa matenda, matenda a impso, ndi khansa ya m'mapapo. Koma faifi tambala kawopsedwe kumaonekera pokhapokha ngati izo ziri mu thupi lalikulu zedi.
