Ingongoma ukunyibilika lead

Khokela - metal umbala oluhlaza ngenani elikhulu womxhuzulane ethile kanye nekuba kakhulu minimum (unqanyulwe ngemela). Ingongoma ukunyibilika lead Akuve ukuba kwenjenjalo ukunyibilikiswa emlilweni okanye ekhaya. phambili Pure ngokukhawuleza wambu kunye film oxide buze. Xa amaqondo yesiqhelo yipeyinti egalelwe ezininzi asidi.

Ingongoma ukunyibilika ilothe, ngokuba akukho ukungcola, malunga malunga 328 degrees. Ezibunjiweyo uhlobo intsimbi unalo castability elungileyo. Xa ukusebenzisa bakholelwe ukungunda Isanti iyimfuneko ukuba notyhidiweyo waba fluidity elungileyo, ngenxa yoku, baphele kwaziswa lobushushu ngaphezu kwindawo ukunyibilika nama-100-120 degrees. Lula ngomshini, kwaphunyezwa, aphezulu ductility metal laminate ivumela ukuba lincinane sheet ubukhulu lula.

Lokubila of yipeyinti kuluhlu 1749 °.

Xa urhulumente etyhidiweyo isiphathele hexa ebalulekileyo, nto leyo eyandisa kunye lobushushu. uthuli Lead, kunye iperi oxides bakhokelayo ezinobuhlungu ukuze umzimba womntu. Ukubakho kwi eziphilayo ka-0.3 g welothe okanye iincindi zalo, kukhokelela eziyityhefu kakhulu. Kwinkqubo crystallization abakhokele enkulu sinotyekelo shrinkage, oko ngokubanzi malunga ne-3.5%. eqweqweni okhokelayo Umhlaba ifumaneka rhoqo ngohlobo iikhompawundi, ekwimo esulungekileyo, zako inqabile.

Kuye kwafunyaniswa ukuba kakhulu ifumaneka ngohlobo sulfides ematyeni ezahlukeneyo.

Njengoko elimsulwa kulo kusenokuba izinto ezifana kwistibhiya, ubhedu, intsimbi, inkcenkce, bismuth, iarseniki, isodiyam, njl Uninzi ubumdaka ayinqweneleki, ngokukodwa xa kusenziwa kwiindawo ezibalulekileyo, ngokuba akhokelela umntu loyamano iimpawu yemichiza mechanical le sentsimbi. Izinki kunye bismuth ikhokelela nokunciphisa ukuxhathisa asidi. Ubukho wemagniziyam okanye calcium kukhokelela ekwandeni ngamandla, kunye nentsimbi exutyiweyo kunye kwistibhiya, esibonakala ukwanda ezininzi ngenxa yokuqaqadeka.

Copper kwandisa kweelana imveliso akhokelela acid sulphuric, barium kunye lithium nokwanda bobuso. Ingongoma yokunyibilika kwelothe phambi ubumdaka akuthethi enziwe iinguqu ezibalulekileyo. Uluhlu isicelo iimveliso ezivela ebanzi phambili ngokwaneleyo. abasebenzisi eziphambili zezi zixhobo zokufunda luthathwa cable ibhetri yemveliso, apho isetyenziswa njengoko esingxotyeni cable kunye nokuveliswa amacwecwe kwebhetri.

Made shot yepeyinti iimbumbulu. Ingongoma yokunyibilika aphantsi lead avunyelwe ngabazingeli ngaphambili kwenza iimbumbulu kunye shot.

ikhono Anticorrosive welothe kuvumela ukusetyenziswa kwayo ukuze isicelo umaleko olukhuselayo kwi izinto ezenziwe ngentsimbi. Ukongeza, le impahla lead lisetyenziswa ekwenziweni ipeyinti kunye ivanishi. A ingxenye enkulu nqanawa minium, leyo umbala inxalenye kwamanzi enqanaweni, kuba sombala esekelwe phambili.

Esingxotyeni salo phambili iyakwazi ngokukhuselwa ngokudleka sombane kunye yocingo wabeka phantsi komhlaba kunye namanzi-bume engentle. Ngeliphi lobushushu ukunyibilika bakhokele, nebhekile, bismuth kunye isiqalelo esithambileyo esimhlophe, ingqalelo xa kusenziwa iifyuzi zombane. Kude neebhetri namhlanje imfuno okhokelayo-acid kwi leemoto, ukhuselo kunye namanye amashishini amaninzi. Noko ke, kwiminyaka yakutshanje baqala ukusebenzisa ngokubonakalayo iibhetri nickel-isiqalelo esithambileyo esimhlophe.

Abakhokelayo ekwakhiweni ingxubevange lisetyenziswa ekwenziweni babbitt lokuzala solder of nebhekile kunye aluminium lead yoshicilelo. Sheets ezenziwe elikhokelela wasikhusela X-reyi kwaye radiation eqhumayo. Ingozi kwenzeka ngo-1986, xa iChernobyl, kunye radiation kakhulu radioactive, ukuze uyeke inkqubo kwi-reactor, esebenzisa iingxowa shot okhokelayo kunye okusilelayo bakhokele.

Ukukhusela abantu ntaka ufake lo mthwalo, nelothe sheets zasetyenziswa. Iimpawu ezizodwa lead kulo mzekelo yajika ufunwayo.
