Kuponya platinamu kumachitika pogwiritsa ntchito njira ya masitepe ambiri yomwe imaphatikizapo zida zapadera komanso chidziwitso chachikulu cha momwe zitsulo zamtengo wapatali, monga platinamu, zimasungunukira. Njira yopangira platinamu imaphatikizapo masitepe otsatirawa: Chitsanzo cha sera ndi kukonzekera kuponya.

Kuponyera Zodzikongoletsera za Platinamu

Masitolo ogulitsa zodzikongoletsera ndi opanga zodzikongoletsera ena akufuna kusintha mapangidwe awo mwachangu kukhala zinthu zenizeni zomwe zingagulitsidwe. Makampani opanga zinthu zopangidwa ndi platinamu, monga Casting House, angathandize mabizinesi ndi opanga awa kupanga zinthu zapadera kapena kupanga zinthu zazikulu mwa kupereka mwayi wopeza ntchito zapamwamba zopanga zinthu.

Kumvetsetsa Njira Yopangira Platinum

Kupaka platinamu kumachitika pogwiritsa ntchito njira yopangira zinthu zambiri zomwe zimaphatikizapo zida zapadera komanso chidziwitso chochuluka cha momwe zitsulo zamtengo wapatali, monga platinamu, zimasungunukira.

Njira yopangira platinamu imaphatikizapo njira zotsatirazi:

Njira yopangira zodzikongoletsera za platinamu ndi yofanana ndi yopangira zodzikongoletsera zagolide ndi siliva. Kusiyana kwakukulu kokha ndikuti kutentha kwa platinamu kumafunika kwambiri komwe kuli pafupifupi madigiri 1800 Celsius, izi ziyenera kuchitika ndi Hasung Tilting Vacuum Pressure Casting Machine.

Chitsanzo cha sera ndi kukonzekera kuponyera. Chovala cha platinamu chimayamba ndi kupanga chitsanzo cha sera cha momwe chidutswa chomalizidwa chidzawonekere. Chitsanzochi chimalumikizidwa ku tsinde la sera ndi sprue yomwe imapanga njira yomwe platinamu yosungunuka imadzazira mu nkhungu. Nthawi zina mitundu yambiri ya sera imalumikizidwa ku tsinde lomwelo kuti ipangidwe kuponyera kambirimbiri.
Ndalama Zogulira. Chitsanzo cha sera chikayikidwa pa tsinde, chimayikidwa mu botolo ndipo zinthu zogulira zimathiridwa mozungulira. Zinthu zogulira pambuyo pake, chimakhala nkhungu yomwe platinamu yamadzimadzi idzathiridwamo. Kugwiritsa ntchito zipangizo zoyenera zogulira popangira platinamu ndikofunikira kwambiri chifukwa cha kutentha kwakukulu komwe platinamu imasungunula. Komabe, platinamu isanathiridwe mu nkhungu, chitsanzo choyambirira cha sera chiyenera kutenthedwa mu uvuni wapadera. Sera yonse ikasungunuka ndikuwotchedwa, imasiya dzenje mu zinthu zogulira zomwe zimagwiritsidwa ntchito ngati nkhungu.
Kusungunula. Pali mitundu ingapo ya aloyi yodziwika bwino yomwe imagwiritsidwa ntchito popanga platinamu. Yodziwika 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. Aloyi ikasungunuka, imatha kutsanuliridwa mu nkhungu kapena kukakamizidwa kugwiritsa ntchito imodzi mwa njira zingapo.
Kuponya. Ngakhale kuti chitsulo chamadzimadzi chimangothiridwa mu nkhungu, njira zosiyanasiyana zimapereka kuponya kwapamwamba kwambiri polamulira kuyenda kwa chitsulo mu nkhungu. Kuponya kwa centrifugal kumagwiritsa ntchito centrifuge kuzunguliza botolo ndikugwiritsa ntchito mphamvu ya centrifugal kufalitsa chitsulo mofanana mu nkhungu yonse. Kuponya kothandizidwa ndi vacuum kumakoka chitsulo mu nkhungu pogwiritsa ntchito kupopera. Kuponya kwa pressure kumaika botolo mkati mwa chipinda chopanikizika. Casting House imagwiritsa ntchito njira zonse zitatuzi komanso kuponya tochi, komwe kumagwiritsa ntchito tochi kusungunula chitsulo chochepa kwambiri chomwe chimathiridwa mu nkhungu.
Kuchotsa zinthu m'malo mwake Izi zimaphatikizapo kuchotsa zinthu zomwe zayikidwa mu ndalama zomwe zayikidwa, kaya pogwiritsa ntchito njira zakuthupi kapena zamankhwala. Ndalamazo zitha kumenyedwa, kuphwanyidwa ndi madzi kapena kugwedezeka, kapena opanga angagwiritse ntchito yankho kuti asungunuke. Mpweya womwe uli pa chidutswa chilichonse umadulidwa ndikubwezeretsedwanso kuti ugwiritsidwenso ntchito mtsogolo, ndipo chidutswa chomalizidwacho chimatsukidwa kuti chichotse zolakwika zilizonse.
Kufunika kophatikiza chidziwitso chapadera ndi mwayi wopeza zida zinazake kumatanthauza kuti masitolo ambiri osungira zodzikongoletsera ndi opanga zinthu amadalira makampani opanga zinthu za platinamu kuti achite ntchitoyi. Akatswiri omwe amagwira ntchito m'makampani opanga zinthu za platinamu awa ali ndi chidziwitso chofunikira popanga zodzikongoletsera zapamwamba kwambiri. Alinso ndi mwayi wopeza ukadaulo wapamwamba kwambiri wopangira zinthu ndi wa photopolymer.
