583 kuyesedwa kwa golide

Kuwonongeka kumatanthauza kuchuluka kwa golidi mu alloy yomwe miyala yodzikongoletsera imapangidwira. Mu mawonekedwe ake apamwamba kwambiri, chitsulo chamtengo wapatali ndi chofewa kwambiri ndipo chotero sichiyenera kuzipanga zodzikongoletsera kawirikawiri ntchito tsiku ndi tsiku. Kuti apereke mphamvu zofunikira, zilembo zimapangidwa ndi zitsulo zina, zomwe zimagwiritsa ntchito mkuwa ndi siliva. Nthaŵi zambiri, zitsulo zina zimawonjezeredwa ku golide kuti apange mithunzi yosiyana (mwachitsanzo woyera kapena wofiira) ndi katundu wa alloys. Ndalama ya golidi yomwe ili m'zinthu zoterezi ndi kuwonongeka. Mu USSR, 583 zitsanzo za golide zinali zofala kwambiri .

Ndipo ngakhale kale, zinthu za golidi zodzikongoletsera zamtengo wapatali zinkatsimikiziridwa mu magalasi, pamene zinkaganiziridwa kuti 100% golide ndizofanana ndi magalasi 24, ndipo kupezeka kwa zonyansa zilizonse zachepetsa chiwerengero cha makatoni, malingana ndi kuchuluka kwa zowonjezera zina. Machitidwewa alipo mpaka tsopano ku United Kingdom, United States ndi mayiko ena. Mu Ufumu wa Russia, ndipo mpaka 1927 mu Soviet Union, zitsanzo zazitsulo zamtengo wapatali zinatsimikiziridwa mothandizidwa ndi slide dongosolo, la alloy lomwe linali logawidwa magawo 96, osati 24.

Kenaka ku USSR ndi m'mayiko ambiri anayamba kugwiritsa ntchito njira yamakono yolondola. Idawonetsa za chiwerengero cha zigawo zazitsulo zamtengo wapatali mu 1000 zigawo za alloy. Ndi chiwerengero cha ziwalo zomwe golide amatsimikiziridwa, omwe amaveka zodzikongoletsera. Malingana ndi kachitidwe kotero, zimapezeka kuti golidi mu carats 14 imayenderana ndi 583 golide zitsanzo, 18 carats kuti 750 zitsanzo ndi zina zotero. Izi zikufotokozera chiyambi cha zizolowezi zomwe kale sizikudziwika bwino zamatriki. Pamene machitidwe awiriwa akufanizidwa, kutanthauzira kwa golidi woyenga bwino ndi kosavuta. Momwemonso, chitsanzo cha 1000 chiyenera kufanana ndi golidi mu makatata 24, koma mwakuchita sitingathe kupeza golidi wotero ndipo motero nthawi zambiri amatchedwa golide "wangwiro" wa 999 (niti zitatu), ndipo nthawizina ngakhale golide wangwiro wa makotolo 24 amatchedwa chitsanzo 990.

Zida zonse zagolidi zomwe zimagwiritsidwa ntchito popanga zodzikongoletsera zimayikidwa bwino. Kale ku USSR panali mayesero 958, 750, 585, 583 ndi 375. Pa nthawi imodzimodziyo, 583 zitsanzo za golidi zinagawidwa kwambiri. Zitsulo zazitsulozi zingakhale ndi mtundu wosiyana malinga ndi kuchuluka kwa zitsulo zosalimba zomwe zili mkati mwake. Mwachitsanzo, ngati aloyiyi ali ndi magawo 58.3 a golidi, 5.7 mbali zamkuwa ndi magawo 36 a siliva, ili ndi chobiriwira chobiriwira, chiri ndi pinki tinge ndi zokwanira 23.4 zigawo za mkuwa ndi 18.3 magawo a siliva, ndipo zili ndi 33 , Magawo 4 a mkuwa ndi 8.3 magawo a siliva ali kale pabuka.

Pofuna kupeza golidi woyera, omwe amagwiritsidwa ntchito kwambiri popanga zodzikongoletsera ndi diamondi, zitsanzo za golide za 583 zinagwiritsidwanso ntchito. Anali ndi zigawo 16 zamkuwa, siliva 23.7-28.7 mbali, nthaka 8.7 ziwalo, komanso 13-18 mbali ya nickel kapena palladium. M'tsogolomu, m'mayiko onse omwe kale anali Soviet Union, zitsulo 583 za golidi zidasinthidwa ndi 585 zitsanzo, ndipo golidi inayamba kutchuka ndi zitsanzo 750. Tisaiwale kuti mtundu wa golide sikuti umagwirizananso ndi kuwonongeka kwake. Ndi chitsanzo chomwecho, chikhoza kukhala chofiira ndi chachikasu, choyera, chobiriwira komanso chofiirira kapena chakuda.

Chikhalidwe choyambirira cha mtundu wa golidi wodalirika pa chitsanzo chake chinapangidwa pa USSR, pamene malonda a golidi ankapanga golidi ndi mtundu wofanana ndi mtundu uliwonse: 750th mu chikasu, 583 wofiira ndi 375 mu pinki. Koma tsopano pakupanga zodzikongoletsera zomwe zimagwiritsa ntchito mitundu yosiyanasiyana, choncho mtundu wa golidi ungathe kukhala wosiyana ndi zitsulo zopindulitsa zomwe zili mkati mwake, ndipo zitsanzo zomwezo zimakhala zoyera ndi zakuda.
