Isiliva Kutheni mnyama

Kutheni isiliva emnyama? Umba exhalabisa bonke abanikazi zexabiso ezenziwe olu.

Silver - metal wohlobo kunye reactivity ephantsi ngokwaneleyo ukuba yintshukumo oxidant ziqhelekileyo - amanzi kunye nomoya. Nangona kunjalo, phambi kwabo, kunjalo, lula idityaniswe nenye into - i-sulphur divalent. Indlela abasabela ngenxa ivelisa Ag2S - emanzini yesilivere, nto leyo into emnyama. Phantsi kweemeko eziqhelekileyo, izivatho eyenziwe emanzini yesilivere abunjwe ngokucothayo kakhulu. Okokuqala, uqala nihombisa enento inkungu kunzima perceptible ndiyingwevu, ngoko uba patina phantse abamnyama.

Ukuze siqonde isizathu sokuba isilivere ebumnyameni, kufuneka uqonde ukuba kuba imele njenge element imichiza, ekwaziyo lokunxibelelana kunye eziyingqongileyo. Utshaba engundoqo amanene umbala Isilivere H2S sulphur umthengisi (emanzini), nto leyo ekhokelela igcwala yayo. Apho emanzini owomileyo akuthethi ukuba ukusabela enjalo. Ukuze benze oku, ubukho ukufuma. Indlela abasabela Izinga ekwaziyo ukunyusa iqondo lobushushu apho ukwanda emanzini umhlwa unako kukhawuleziswa kakhulu. Umzekelo, ukuba ubushushu ukusuka degrees-20 ukuya ku-40, izinga lwephanyazo konyuso umhlwa layi-25!

Xa umoya sikhulule izinto ezikhoyo ezifana ozone, ammonia, hydrogen chloride, emanzini, sulphur dioxide , nesalfure free. Kuxhomekeka uyazikhomba ezo izinto ukufuma umhlwa yesilivere unako mkhulu okanye okuncitshiswe. Igcwala ngenxa Ag2S metal ekuhambeni kwexesha kwandisa ukutyabeka umaleko wenqaku.

Ngoko kutheni mnyama isilivere kucaca. Kodwa ngaphandle uthe hydrogen sulphide siqulethe umoya namanzi. Le ke into elandelayo. Xa umxholo aphezulu amanzi yendalo basebenzisa oku umchiza njenge amayeza - sulfides (emanzini) amanzi.

Lo mthombo uphambili ezikhutshwayo emanzini emoyeni - amashishini kwimizi avelisa ifayibha ngumntu, izicokisi oyile kunye nezityalo coke, kwakunye phantse kuzo zonke izithuthi. Kulo mzekelo, kubonakala ngathi kwimveliso yokubola into ephilayo (inkunkuma).

Ukususela oko mnyama isilivere kwiimeko eziqhelekileyo, ukuba anithanga ukuthintela ukuba adibane ngamanzi? Yenzani umboniso emanzini kwi isihombiso kwaye contact okanye kufutshane nje ukufumana izinto eziphilayo, umzekelo, iikhompawundi irabha, iiplastiki.

Musa ukulibala ukuba umzimba wethu ngokwawo wokuvelisa nesalfure. It engena evela ngaphandle komzimba kunye nokutya okanye iziyobisi (streptotsidom, sulphadimezin Sulfazin, namafutha aqholiweyo ezahlukeneyo kunye namanye amalungiselelo. Ekuhambeni ukutya, nesulfure ukuze kuncitshiswa abe H2S obuphuma umphezulu isikhumba kunye umbilo, apho wadibana emakhonkcweni, amaso kunye nezinye othandekayo imihombiso zethu.

Emva kokuhlolisisa zonke iintshaba zesilivere, ngoku ukuqonda ukuba kutheni isilivere elimnyama, kodwa siyaqonda ukuba siphephe loo Browning nzima. Ngenxa asinako ukuphila ngaphandle umoya, amanzi, kwaye akanako umva abasabela ngayo umzimba wayo siqu.

Kodwa akukho zonke izizathu zesilivere kutheni mnyama. Ekubeni eli izinto wentsimbi alisetyenziswa ngendlela esulungekileyo, kodwa kuphela aluminiyamu, ngokufuthi ezikuyo zezobhedu. Emoyeni kubhaliwe oxidized ku Cu2O, ukufumana nombala bubomvu. Ukuba imveliso kungakhankanywanga umaleko ibakhusela, umzekelo, Radium okanye palladium, baya kusoloko ukungcolisa. I onguwumbi kunikwa.

Yintoni onokuyenza ukuze uyolule ubomi zesilivere, kunye nokugcina ubuhle lokuqala izacholo kulo? Kufuneka ukuba uqiniseke ukuba imveliso hayi nge welding, zange kwiindawo ezimanzi. Emva nabo kufuneka zicocwe ukusuka netuwa esikhumbeni. Kwakhona luncedo kakhulu ngamaxesha nokucoca ukuthatha umhombiso ezivenkileni izacholo okanye ukucoca kubo ngokusebenzisa amanzi anesepha kongezwe ammonia.
