Barta barafku ka mid ah hogaanka

Hoggaami - biraha cado buluug ayaa weyn cuf gaar ah iyo qalbi engegnaantooda xooga ugu yar (waa laga gooyn karo mindi). barta barafku ka mid ah hogaanka Waa sida in ay ku dhalaali kara dabka ama guriga. hogaanka ka daahirane ah waxaa si deg deg daboolay film xabagta iyo dhaawoco. At heerkulka caadiga ah hogaanka waa inert in acids ugu.

barta barafku ka mid ah hogaanka, isagoo nijaas, ma, qiyaastii ku saabsan 328 digrii. The shubay foomka of biraha ayaa castability wanaagsan. Marka hogaanka shubtay galay caaryada cammuudda waa lagama maarmaan in biraha lahaa isbeddello wanaagsan, in ay dhamaadka this, dhalaalisa la soo geliyo si heerkul ka sarreeya dhibic barafku qiyaastii 100-120 digrii ah. Si fudud machined, been abuurtay, laminate biraha ductility sare u ogolaanaya in ay sheet oo dhumucdiisuna waxay ugu yar ee si fudud.

Ujeedadu waxay karaya ee hogaanka waa kala duwan 1749 °.

In gobolka shubay waxa ay leedahay Degenaansho weyn, taas oo kordhinaysa heerkulka. busta sunta rasaasta, iyo labo ka mid ah oxides hogaanka waa sun ah in jidhka bini'aadamka. Joogitaanka ku shaqeeyo of 0.3 g of hogaanka ama qaybaha, waxay keenaysaa in lagu sumoobo daran. In habka crystallization hogaanka weyn u nugul yaraanshaha ah, guud ahaan waxay ku saabsan tahay 3.5%. The dhulka udubyadiisa hogaanka waxaa inta badan laga helaa foomka xeryahooda, qaab saafi ah, waa arrin naadir ah.

Waxa la ogaaday in inta badan waxaa laga helaa qaab sulfides dhagaxyada kala duwan.

Sida nijaasta waxa ku jira xubno laga yaabaa in sida midabyo, copper, birta, iyo waxa daasadda, bismuth, arsenic, sodium, iwm Inta badan nijaasta ah waa loo baahnayn, gaar ahaan soo saaridda ee qaybo ka mid muhiim ah, maxaa yeelay, waxay keeni beddelid ka mid ah guryaha kiimikada iyo farsamo ee biraha. Zinc iyo bismuth hogaanka yareeyo caabiga acids. Joogitaanka magnesium ama calcium keenaysaa in la kordhiyo xoog, iyo biraha alloyed leh midabyo, lagu gartaa kororka badan qalbi engegnaantiinna aawadeed.

Copper kordhisaa iska caabin ah ee alaabta hogaanka in acid sulfuric, barium iyo lithium engegnaantiinna kordhay. barta barafku ka mid ah hogaanka ay goobjoog ka ahaayeen nijaasta ma mari isbedel la taaban karo. kala duwan ee codsiga ee alaabta ka soo hogaanka balaadhan oo ku filan. macaamiisha Major ee wax this waxaa loo arkaa inay cable iyo batari-soo-saarka, halkaasoo loo adeegsaday sida galkeeda cable iyo soo saaridda of taarikada batteriga.

Dhammeeyey shot iyo rasaas hogaanka. barta barafku yar yahay ee hogaanka u ogol yahay ee la soo dhaafay by ugaarsadaha dhigi rasaas iyo shot.

awoodda Anticorrosive ee hogaanka u ogolaan isticmaalkeeda codsan lakabka ilaaliya alaabta bir ah. Intaa waxaa dheer, hantida this of hogaanka waxaa si balaadhan looga isticmaalaa in soo saaridda ee rinjiga iyo varnishes. Qayb ka mid ah minium markab, taasoo midabka qaybta quuska ee doonnida, waa Midabka ku salaysan hogaanka.

galkeeda hoggaanka awood u difaacato korontada daxalka iyo telefoonka cable dhigay ka hooseeya dhulka iyo biyaha ee jawi colaadeed. Marka waxa heerkulka aad u cabsiiyey hogaanka, iyo waxa daasadda, bismuth iyo cadmium, tixgelinayo in soo saaridda ee fiyuusyada korontada. Ilaa baytariyada baahida maanta hogaanka-acid ee baabuurta, difaaca iyo warshadaha kale oo badan. Si kastaba ha ahaatee, sannadihii la soo dhaafay waxa ay bilaabeen in ay si firfircoon u isticmaalaan baytariyada nickel-cadmium.

Lead in Halabuurka daawaha waxaa si balaadhan looga isticmaalaa in soo saaridda ee Alxan Babbitt dhalista ah iyo qasacad iyo Alloys hogaanka daabacaadda. Sheets ee X-rays hogaanka-gaashaan iyo dhigtay shucaaca radioactive. shil ka dhacay 1986, ee Chernobyl, Ulasocto shucaaca radioactive daran, si ay u joojiso habka labaad ee warshadan, iyadoo la isticmaalayo bacaha of shot hogaanka iyo meelaha banaan hogaanka.

Si loo ilaaliyo dadka ku helicopter ah culus u hoydeen, go'yaal hogaanka la isticmaalay. The guryaha gaarka ah ee hogaanka ay dhacdo in this soo baxday in lagama maarmaan.
