Kodi pali 925 zagolide

Golide kasakaniza wazitsulo GOST anapereka ena phindu n'zosangalatsa kumva - mayesero amenewa, omwe angathe kudziwa chiwerengero cha zidutswa za zitsulo zamtengo wapatali zopezeka m'madera 1000 aloyi golide. Choncho, Chitaganya cha Russia mwalamulo 925 golide palibe. Pa maonekedwe osiyanasiyana zodzikongoletsera pafupipafupi funso: "Kodi pali 925 golide?" Nthawi zina funso limeneli lili yankho: ". Ndi golide woyera" Ndithudi, woyera golide aloyi ndi a chitsulo wolemekezeka ndi wina woyera zitsulo: manganese, faifi tambala kapena palladium.

Zokha golide woyera anali mu 1920 ndipo tsopano wakhala chuma yapamwamba kwambiri zosiyanasiyana makampani zodzikongoletsera kuti kulenga katswiri wawo kuchoka kwa izo. Choncho, mankhwala amenewa ndi ayamba wotchuka pakati connoisseurs zodzikongoletsera zabwino. Mawu akuti "woyera" amatanthauza osiyanasiyana mwachilungamo lonse la mithunzi kuchokera wotumbululuka zofiirira ndi wotumbululuka chikasu, mungathe inadza wotumbululuka pinki. Nthawi zina makampani zodzikongoletsera kuti pamwamba woyera, ntchito ❖ kuyanika wa rhodium, omwe ndi ofunika kwambiri kuposa golide. ❖ kuyanika Izi zimamupatsa malonda walani, kumaonjezera kuuma awo ndi kuvala kukana, kuteteza zimakhalapo ndi kuwonongeka.

Kupeza woyera-mtundu golide aloyi zitsulo kawirikawiri amagwiritsidwa ntchito Kuwonjezera izo palladium. Ngakhale zambiri mitundu kwambiri choyera aloyi Kuwonjezera pulatinamu. Mu embodiments kwambiri ntchito wotchipa Kuwonjezera faifi tambala. Komabe, madokotala anakhazikitsa kuti pali siligwirizana ndi faifi tambala munthu mmodzi eyiti, kotero mu 2000 mu mayiko a ku Ulaya mu zodzikongoletsera lopangidwa ndi woyera golide faifi tambala anawonjezera ndikoletsedwa. Katundu wa kasakaniza wazitsulo woyera golide ndi osiyanasiyana malingana ndi kufanana ndi mitundu anawonjezera kuti aloyi zitsulo Koma 925 agolide Russia si inakhazikitsa, kuyambira zonse zagolide, kaya akhale a mtundu wawo, mogwirizana ndi kukhazikitsidwa zitha kukhala 375, 583, 585, 750 ndi 958 zitsanzo.

925 Ndi ambiri siliva nyemba. Poyamba, asanayambe woyera golide ndi siliva kawirikawiri amagwiritsidwa ntchito kupanga zodzikongoletsera diamondi, monga woyera amasonyeza bwino kwambiri malangizo amenewa Walani ndi amalenga zotsatira zina kuunikira. Zotsatira za diamondi anaikidwa mu zinthu za golide woyera ngati aloyi zagolide ndi palladium amakhala pulasitiki ndi zofewa, choncho ndi bwino makamaka mu tsamba la izo miyala yamtengo wapatali. Komabe, palibe ntchito 925 golide, ndipo ambiri 750. Izi aloyi ternary, kuyambira zambiri yophatikiza kuposa golide, mkuwa, siliva (nthawizina nthaka, faifi tambala ndi palladium), zingakhale ku mitundu yosiyanasiyana - kuchokera utoto zoyera.

Popanda iye, ndithu ambiri anayala aloyi golide 585. The zikuchokera golide 585 komanso chimakhala atatu njira, mtundu alinso osiyanasiyana mitundu yosiyanasiyana, malingana ligature ntchito - zofiira zoyera. Malinga kapangidwe kake, zingabweretse kuuma osiyana ndi kutentha osiyana kusungunuka, zambiri chotero aloyi ali kwambiri Yankho bwino zakudya. Otsika chitsanzo 375 ambiri ali ndi pang'ono asowetsedwa pabuka mtundu ndipo imvi kamvekedwe imfa ya kupukuta.

Chitsanzo chapamwamba golide - ndi aloyi mayesero 958, iyenso ternary aloyi ndi Kuwonjezera wa siliva ndi golide, mkuwa. Chifukwa okhutira mkulu wa golide ndi zofewa kwambiri choncho pogwiritsira ntchito zodzikongoletsera ku aloyi kupukuta kuwasunga yaitali. Nthawi zambiri ali abwino zofewa yowala mtundu wachikasu, amene ali pafupi ndi mtundu wa golide woyenga bwino, ndipo makamaka ntchito popanga mphete.
