Yiziphi amasampula esiliva? Imininingwane amasampula esiliva

Ezinye Kungase kukumangaze yokuthi ubucwebe kuyaqabukela ekhiqizwa kusuka impahla okumsulwa. Lokhu kungenxa izakhiwo ngokwabo namatshe ayigugu, nokuthi noma isiliva okumsulwa akuvamile ukukhiqiza. imikhiqizo Clean ngokuvamile aba lowehlukile futhi izindlela ezihlukene.

Yiziphi amasampula isiliva lapho wavela khona na?

Isiliva, efana nezinye izinsimbi eziyigugu, indaba alloying kungenziwa buhlanjululwe cishe Infinitum isikhangiso. Impela, olimaza ukubaluleka kwayo. Yesilinganiso ukuhlukanisa izinga yesiliva kubantwana "alulaze" kuyinto elula kangaka cha.

Ukuze ngandlela-thile ukuhlukanisa mbumbulu kusukela umkhiqizo yangempela, futhi izibonelo zalokho uhlelo yethulwa. Isebenza kusukela 1927 futhi esasebenza nanamuhla endaweni Russia nase CIS amazwe. Ngokwe-metric, izinga lomkhiqizo kunqunywa eziyigugu umthamo impahla abahlanzekile 1000 amagremu. Okusho ukuthi, uma isampuli yomkhiqizo 925, kusho ukuthi kwelinye kilogram i ingxubevange ezifana isiliva 925 amagremu 75 izinsimbi alloying.

Lapho ubheka ikusasa, ethi aphakeme esiliva Assay - 960. Kodwa kungani 1000? Isiliva ngokwawo impahla soft kakhulu, ngakho-ke kuyadingeka ukuba 'liqinise "nickel, ithusi, zinc noma aluminium. Elivame ukusetshenziswa kakhulu zethusi. Ngokubambisana namakhamphani izinsimbi ezinjalo, uzuza amandla. Kuyaphawuleka ukuthi Alloys 80% -S 'non-ngibazisa ngokusemthethweni eRussia.

esiliva lobuchwepheshe

Isiliva ngaphandle isampula, iphesenti umthamo ngezansi 80, okuthiwa metal lobuchwepheshe. Ukuze yokukhiqiza imigexo izinto ezinjalo alisetshenziswa. Kodwa inkulumo mayelana izinga yayo ompofu akukalungi kahle efanele. Iqiniso ukuthi liye landa ngamandla. Metal ngenxa impahla yayo ngokomzimba - i material ekahle womshini izingxenye for umsakazo. Silver isetshenziswa kukhiqizwe edluliselwe.

Lezi amalungelo ke wathola ngenxa ukukhanya okusezingeni eliphezulu conductivity kagesi.

Kwakucatshangwa ukuthi kusukela kule esiliva zingaba nezinto zokuhloba uma ungeyena isampula ayisisekelo. Kodwa-ke kufanele kuqashelwe ukuthi metal akubhekwa eziyigugu.

Amafomu amasampuli esiliva

Imininingwane amasampula esiliva (okuyizinto amasampula esiliva) ukukhuluma okwengeziwe.

I sensimbi, okuyinto kubhekwa eziyigugu, kumakwe ngale ndlela:

• 800 - sezipuni;
• 830 - esetshenziswa akhiqize glassware nezinto zokuhloba engabizi;
• 875 - yasekhaya;
• 925 - ubucwebe, owande;
• 960 - isampula esiphezulu;
• 999 - isiliva esivelele.

Imininingwane amasampula esiliva

Yiziphi amasampula esiliva, sithole. Manje, cabangela injongo yabo.

1. Isiliva 800 m "inhlamba" kusho ukuthi akuyona esingaphansi ngo-80% okumsulwa. Kuyinto, eliqinile kakhulu futhi has a high asakazwe izakhiwo. Kodwa kukhona lokususa - ngokushesha oxidized endaweni evulekile. Kungenxa yokuthi esiliva alisetshenziswa ngokwenza ubucwebe. Esinye isizathu - has a umthunzi esasenza ephuzi ukuze ithusi, ngakho kalula esihlukile izinhlobonhlobo ubucwebe.
2. Kusobala ukuthi ukwengeza amaphesenti amathathu esiliva ingxubevange, hhayi kakhulu okushintsha izakhiwo ngokomzimba we umkhiqizo osuphelile. Ngakho-ke, injongo eyinhloko isampuli - yokukhiqiza izimfoloko, nezinkezo nemimese.
3. Uma uhlu isampula esiliva - iziphi izinhlobo - the 875-mina isetshenziselwa ubucwebe. Umhlobiso plan onjalo kufanele ngokuthi "ikilasi umnotho". Iqiniso lokuthi ukubaluleka imikhiqizo ingaphansi futhi ngenxa yezikhwepha anda, uma kuqhathaniswa nabangu yakuthatha, kunzima ukwenza filigree umsebenzi.
4. 925-mina sampuli esiliva - okuvame kakhulu ebhizinisini ubucwebe. Okokuqala, amandla eliphansi nezinye izinsimbi odlulisela isici esihle esiliva bezinto. A ukungaguquguquki sasivumela ezithambile kwenza kube nokwenzeka ukukhiqiza imihlobiso ekhexisayo. Ukuphishekela konke lokhu kwenza, isiliva omkhulu kugcina ezakheke.
5. 960-mina sampuli ejwayelekile lwemigexo. izakhiwo Visual nezingokwenyama ke kufana 925-th. Nokho, usengozini yokuthola umonakalo lokukhanda. Inzuzo kuphela - cishe akusho oxidize futhi, ngenxa yalokho, yini abamnyama.

Amasampula zesiliva ukuthi kuyini nokuthi lokho ukusetshenziswa? Umbuzo likubeka ngokucacile. Wonke umuntu kumele ngokuzimela unqume ukuthi izakhiwo kumele abe umkhiqizo ukuthi ukulungele ukuthenga.

isiliva esivelele

Manje uyazi izinhlobo esiliva. Yiziphi isampula esiliva nendlela isampuli ibekwe ku umkhiqizo osuphelile - ezitholakele. Manje, ake sixoxe metal okumsulwa.

Isiliva, kwasho isampula 999th, uthambile. Kuyinto metal okumsulwa, ngakho-ke alisetshenziswa ngokwenza ubucwebe. Its lula kakhulu ukuze agobe noma aphule. Uma wenza uhlelo nomhlobiso esiliva esihle, ngaphezu kwalokho, ngeke ngokushesha ulahlekelwe umumo, futhi ngokushesha eshintsha umbala waso: metal oxidizes ngokushesha bese uba libe buthuntu.

esiliva Pure osetshenziselwa sokuncibilikisa ingots noma ngalendoda zemali. Ngamandla abo, lezi izinto azisetshenziswa ekuphileni kwansuku zonke, okuyinto enciphisa ukulimala ebusweni.

Indlela ukunquma izinga yendlu esiliva?

ubuchwepheshe besimanje ukuvumela ukukopisha ubucwebe ukuze cishe akunakwenzeka ukuhlukanisa kubo kusukela into yangempela. Kodwa namanje ukubuyela umkhiqizo ezinsukwini ezingu-14 engakaze kukhanselwe ngoba, ngibuyele ekhaya futhi inciphise injabulo zobuchwepheshe ezikhiqizwa njalo, sincoma ukuthi afeze isivivinyo esilula ukusiza ukuthola indlela yokwakheka obakhathalelayo.

Manje ngoba sewuyazi ukuthi yiziphi isampula esiliva. Kodwa singababona kanjani ubuqiniso umkhiqizo?

1. Eyokuqala futhi omunye isivivinyo ephumelela kunazo - hlola uzibuthe. esiliva Real ngeke akhangwe. Nokho, lesi akusona metal kuphela oluwashalazelayo "ukukhanga" kukazibuthe. Ngakho ukuthi kufanele kube khona ukuhlolwa eyengeziwe.
2. Ungadlala futhi conductivity ezishisayo. Isiliva ngokushesha uthatha phezu ezingeni lokushisa elifanele. Ngamafuphi - kweso ukufuthelana esandleni futhi ngokushesha kuphole ngamanzi abandayo.
3. Kungenjalo, ingase inkomba esetshenziswa iodine. Ukwehla iodine izohamba endaweni emnyama. Kodwa khumbula, futhi lokho ukuhlanza ibala ngisho simple.

Asincomi eguqa futhi notching umkhiqizo. Uma kuba inkohliso, kuyobe sekuba i-kungenzeki ukubuyela, futhi ugcine umkhiqizo spoilt - baphonse imali phansi abakhwabanisi.

Manje sonke siyazi ngalokhu metal kuyinto: yiziphi amasampula esiliva, ezisetshenziswa. Ngakho, lapho uthenga imikhiqizo uzokwazi ukwenza ukukhetha okufanele.
