Kungakanani kuyinto igremu zesiliva - impahla nezindinganiso ezingokomoya

Indoda ozihambela emigwaqeni, kucatsanisa, indlela amagremu kakhulu isiliva eyodwa igremu zegolide, ukhetha metal ezibizayo. Igolide, yebo, ezibizayo okuningi: umkhiqizo ke, akubona bonke abantu angaba namandla okuwunikela.

Eqinisweni, esiliva bekulokhu metal ezibalulekile, hhayi ngokwezinto ezibonakalayo kuphela kodwa nangokomoya. Kwaba inombolo yakhe ibonisa isimo izicukuthwane ocebile namakhosi. Abanye abantu bakuleli zwe metal lasendulo kwaba uphawu zenyanga futhi njengengcwele. Uhlanzekile nobumsulwa esiliva livele isonto zaqala ukucabangela lesi metal yesihle. izimfanelo Engcwele kwale nto asetshenziswa zonke izinkolo zezwe kube yilolu suku. Ngakho-ke, indlela amagremu kakhulu zesilivere, ukuze kholwa nakanjani asihlobene.

ngezici zawo zokwelapha ziye eyaziwa kusukela ezikhathini zasendulo, futhi ukuthuthukiswa baye wabonakalisa ngezimanga ososayensi ubuchwepheshe. Ikhono esiliva decontaminated amanzi namanzi ekhona esiliva - ukuphulukiswa futhi ekuvuseleleni umzimba, zaziwa kubo bonke. Namuhla, ama-ion esiliva kunezelwa izimonyo nemithi.

Okwamanje izinqolobane emhlabeni esiliva bomdabu Akukho lutho olusele cishe ngokuphelele: kuphela kwamanye amazwe, zikhona izimali ezifakwa kwezohwebo. Kuze kube manje, kungenzeka kakhulu ukwamukela metal njengoba leyavela e ukucutshungulwa imikhando ezithile. Lokhu kuhlanganisa ukukhiqizwa ithusi, phambili, i-zinc negolide. Ngakho, kokucutshungulwa isilinganiso mayelana amathathu amakhilogramu zethusi noma ukuhola-zinc-ore, ukunikeza 1 igremu esiliva. Ngenxa okuqukethwe okunjalo enkulu izindleko metal kuyinto kakhulu.

Isiliva injalo emsulwa nezimo kakhulu futhi ethambile izici mechanical, ngakho ukwenziwa zokuhloba ke engeza nezinye izinsimbi. Ukuba khona ukungcola ezengeziwe kubonisa amagremu kangakanani esiliva. Imikhiqizo kokuba evamile 925, iqukethe ukubunjwa yayo ayisihiyagalolunye nambili nesigamu amaphesenti esiliva elicwengekileyo, asele eyisikhombisa nengxenye per cent - zethusi. ubucwebe Kwimakethe yomhlaba ngokuyisisekelo nje ukuhlolwa okunjalo.

Ukwehlukahluka kwezimangaliso imikhiqizo ahlinzekwa ngeke nentshisekelo zonke umthengi, ngisho uma ethanda igolide. Ezokudla izinto, isikhumbuzo izibaya kanye umentshisi ingane nezinkezo futhi rattles ku izinyo wengane yokuqala, kweqa, amasongo, namacici, amaketanga namasongo - lokhu akulona lonke uhlu uhla atholakalayo. Ukuba yinkimbinkimbi, okwakhe kanye nekhwalithi umsebenzi inquma amagremu kangakanani esiliva kulesi sihloko.

Kukhona isampula futhi aphansi. Kule esiliva ezinsukwini ubudala, ngokuvamile kakhulu ekhiqizwa zemali nezinto. Abavubukuli bathole zemali lasendulo emihlanu wokuhamba isampuli, uhhafu kuphela eziqukethe esiliva, bonke abanye - ikakhulukazi ithusi. zemali zomlando, izinto umhlobiso kanye tableware, ekhiqizwa eRussia tsarist, kungase kube 750, 800, 830, 900, 916 isampula. izinto zesiliva ekukhiqizweni ngesikhathi Soviet engenanzuzo engaphezu kwamashumi amabili amaphesenti amanyela. Yeka ukuthi kuyinto 1 igremu esiliva esetshenziswa kule mikhiqizo luncike zomlando eziligugu into.
