Zothetsera

Kuponyera platinamu kumachitika pogwiritsa ntchito njira zingapo zomwe zimaphatikizapo zida zapadera komanso chidziwitso chambiri cha momwe zitsulo zamtengo wapatali, monga platinamu zimasungunuka. Kuponyera kwa platinamu kumaphatikizapo izi: Chitsanzo cha sera & kukonzekera kuponya.

Kuponyera Zodzikongoletsera za Platinum

Malo ogulitsa zodzikongoletsera ndi ena opanga zodzikongoletsera amafuna kuti azitha kutembenuza mwachangu mapangidwe awo kukhala zinthu zakuthupi zomwe zingagulitsidwe. Makampani opanga ma platinamu, monga Casting House, atha kuthandiza mabizinesi ndi opanga mabizinesi awa kupanga zidutswa zamagulu kapena ntchito zazikulu zopanga popereka mwayi wopeza ntchito zoyambira.

Kumvetsetsa Njira Yopangira Platinum

Kuponyera platinamu kumachitika pogwiritsa ntchito njira zingapo zomwe zimaphatikizapo zida zapadera komanso chidziwitso chambiri cha momwe zitsulo zamtengo wapatali, monga platinamu zimasungunuka.

Njira yopangira platinamu imakhala ndi izi:

Njira yopangira zodzikongoletsera za platinamu ndi yofanana ndi golide & zodzikongoletsera zasiliva. Kusiyana kwakukulu ndi kutentha kwa platinamu ndikokwera kwambiri komwe kumafunikira pafupifupi. 1800 degree celsius, izi ziyenera kuchitidwa ndi Makina a Hasung Tilting Vacuum Pressure Casting.

Wax chitsanzo & kuponyera kukonzekera. Chidutswa cha zodzikongoletsera za platinamu chimayamba ndi kupanga chitsanzo cha sera cha momwe chidutswa chomaliza chidzawoneka. Chitsanzochi chimamangiriridwa ku tsinde la sera ndi sprue kuti apange njira yomwe platinamu yosungunuka imadzaza mu nkhungu. Nthawi zina mitundu ingapo ya sera imalumikizidwa ku tsinde lomwelo popanga kangapo.
Investment. Sera ikayikidwa pa tsinde, imayikidwa mu botolo ndipo ndalama zogulira zimatsanuliridwa mozungulira. Pambuyo poyika ndalama zogulira, imakhala nkhungu yomwe platinamu yamadzimadzi idzatsanuliridwa. Kugwiritsa ntchito zida zoyenera zogulira popanga platinamu ndikofunikira kwambiri chifukwa cha kutentha kwakukulu komwe platinamu imasungunuka Kutentha. platinamu isanatsanulidwe mu nkhungu, komabe, phula loyambirira liyenera kutenthedwa mu uvuni wapadera. Sera yonse ikasungunuka ndi kutenthedwa, imasiya kabowo kamene kamakhala ngati nkhungu.
Kusungunuka. Pali ma aloyi angapo omwe amagwiritsidwa ntchito popanga platinamu. Zofala kwambiri ndi Platinum 900 Iridium, yomwe imasungunuka pa madigiri 3,250 Fahrenheit; Platinum 950 Iridium, yomwe imasungunuka pa madigiri 3,236 Fahrenheit; Platinum 950 Ruthenium, yomwe imasungunuka pa madigiri 3,245 Fahrenheit; ndi Platinum 950 Cobalt, yomwe imasungunuka pa madigiri 3,182 Fahrenheit. Aloyiyo ikasungunuka, imatha kutsanuliridwa mu nkhungu kapena kukakamizidwa kugwiritsa ntchito njira zingapo.
Kuponya. Ngakhale zitsulo zamadzimadzi zimatha kutsanuliridwa mu nkhungu, njira zosiyanasiyana zimapereka zopangira zapamwamba kwambiri poyendetsa kutuluka kwachitsulo mu nkhungu. Kuponyera kwa centrifugal kumagwiritsa ntchito centrifuge kupota botolo ndikugwiritsa ntchito mphamvu ya centrifugal kufalitsa zitsulo mofanana mu nkhungu. Kuponyera mothandizidwa ndi vacuum kumakokera zitsulo mu nkhungu pogwiritsa ntchito kuyamwa. Kuponyera kokakamiza kumayika botolo mkati mwa chipinda choponderezedwa. Casting House imagwiritsa ntchito njira zitatuzi komanso kuyatsa nyali, komwe kumagwiritsa ntchito nyali kusungunula chitsulo chochepa kwambiri chomwe chimatsanuliridwa mu nkhungu.
Kuchotsera Izi zikuphatikizapo kuchotsa kutaya mu ndalamazo, kaya mwakuthupi kapena mankhwala. Ndalamazo zimatha kunyulidwa, kuphulika ndi jeti yamadzi kapena kugwedezeka, kapena opanga angagwiritse ntchito njira yothetsera vutoli. Chidutswa chilichonse chimadulidwa ndikusinthidwanso kuti chidzapangidwenso mtsogolo, ndipo chidutswacho chimatsukidwa kuti chichotse zolakwika zilizonse.
Kufunika kophatikiza chidziwitso chapadera ndi mwayi wopeza zida zenizeni kumatanthauza kuti masitolo ambiri odzikongoletsera ndi opanga amadalira makampani opanga platinamu kuti achite izi. Akatswiri omwe amagwira ntchito m'makampani opanga platinamuwa ali ndi chidziwitso chofunikira kuti apange zodzikongoletsera zapamwamba kwambiri. Amakhalanso ndi mwayi wogwiritsa ntchito matekinoloje opangira ma photopolymer.
