Chitsanzo 375 zagolide

Gold ndi zitsulo okha mu dziko, ndi wokongola yowala chikasu woyera popanda zina. golide Natural ali luster wabwino, umene kwambiri kumatheka chifukwa kupukuta. Childs, golide akamagwira masuku pamutu wa madipoziti achilengedwe, kapena kudutsa m'zigawo za miyala ina ku ores. Native golide zachilengedwe ndi ambiri si koyera, lili ngati zosafunika chachikulu cha mkuwa, siliva, komanso zina akukumana zinthu zina zambiri. Choncho, ncholinga kuyeretsedwa kwake golide pansi chithandizo chapadera (kuyenga) pa migodi golide.

golide woyengeka kale opangidwa 99,99% mu mawonekedwe a mipiringidzo waya, zojambulazo, Mzere ndi zakudya zina mayiko. Mu njira imeneyi ndi zofewa ndi ductile zitsulo, mwachitsanzo kuchokera galamu imodzi ya waya zitsulo akhoza anakoka ndi kutalika theka la makilomita atatu. Makampani zodzikongoletsera kwa kupanga chokongoletsera golide kale ntchito kasakaniza wazitsulo zosiyanasiyana. kasakaniza wazitsulo onsewa ndi zina golide okhutira, ndipo monga iwo amawatumiza chitsanzo. The zili pansi penipeni zitsulo ndi chamtengo wapatali 375 golide nyemba.

Kasakaniza wazitsulo wa nyemba ndi lopangidwa 37,5 yekha% golide woyenga bwino, zigawo zikuluzikulu zinanso ndi mkuwa, siliva. makampani Akatswiri zodzikongoletsera zina kuzitcha izo golide-mkuwa, siliva aloyi. Malinga ndi mfundo Russian 5 yonse ya kasakaniza wazitsulo limene 375 chitsanzo golide umagwiritsidwa ntchito. kasakaniza wazitsulo onsewa zambiri zokha mu mlengalenga yozungulira, kotero mbali kwambiri zimasokoneza ntchito yawo. Uthunthu wonse wa mitundu ya kasakaniza wazitsulo izi ranges ku chikasu wofiira, koma nthawi chikugwirizana kwakukulukulu ndi aloyi 585 otchedwa "samovar" golide wofiira. Kasakaniza wazitsulo ndi mtundu pinki, ndi cholimba kwambiri ndi kwambiri, iwo amalabadira zakudya.

Ngakhale kuti otsika zitsanzo golide, icho ntchito makampani zodzikongoletsera. Childs, kasakaniza wazitsulo awa ntchito popanga mphete. Latsopano la Russia palibe kasakaniza wazitsulo muyezo m'munsi nyemba, koma ku Ulaya ntchito golide zitsanzo 333, chomwenso ndi ntchito kuti zodzikongoletsera zokongoletsera. Gold kasakaniza wazitsulo nyimbo zosiyanasiyana amagwiritsidwa ntchito makampani zodzikongoletsera, monga pamene anawonjezera kuti mitundu yosiyanasiyana n'zotheka kupeza mbuye kasakaniza wazitsulo zosiyanasiyana: wofiira, pinki, zobiriwira kapena zoyera, komanso osiyanasiyana lalikulu la mitundu wapakatikati.

Nthawi zambiri chifukwa cha ulimi wa kasakaniza wazitsulo zodzikongoletsera ntchito, wopangidwa mwa zigawo zambiri. Ngati golide nyemba 375 analandira makamaka chifukwa Kuwonjezera zamkuwa ndi siliva aloyi, zitsanzo otsala monga ligatures amagwiritsidwa ntchito palladium, pulatinamu, nthaka, cadmium ndi faifi tambala. Aliyense zikuluzikulu za aloyi amatha kupatsa katundu osiyana. Silver zimapangitsa ductile aloyi golide ndi malleable ndi opepuka. Kuwonjezera zamkuwa kumawonjezera kuuma aloyi, koma wake kukana dzimbiri pamene kuwonongeka. Komanso, munthu wotero aloyi zikuchoka yowala hue wofiira.

Kuwonjezera cadmium zimapangitsa fusible aloyi ndi kawirikawiri amagwiritsidwa ntchito ngati golide-solder. Iwo amapereka katundu yemweyo, nthaka, mu Komanso kumachititsa ndi aloyi, zomwe zimathandiza kuti ntchito mu kupanga golide woyera. zitsulo izi mtengo monga pulatinamu ndi palladium-golide kasakaniza wazitsulo opatsa plasticity, elasticity ndi kwambiri kuwalitsa iwo. Komanso, kuwapatsa mkulu dzimbiri kukana. Komabe, golide 375 ndi chitsanzo amapangidwa powonjezera zitsulo izi. The Gawo ndi golide, siliva ndi mkuwa ake.
