Ingoganizirani kukhala ndi mphete yomwe singakande ndipo idzakhalabe yokongola ngati tsiku lomwe mudangogula kumene.
Tungsten yoyera ndi chitsulo cholimba kwambiri chachitsulo chomwe chimapanga kachigawo kakang'ono kakang'ono ka dziko lapansi (pafupifupi 1/20 ounce pa thanthwe). Tungsten sichimachitika ngati chitsulo choyera mwachilengedwe. Nthawi zonse imaphatikizidwa ngati cholumikizira ndi zinthu zina. Kukana kwambiri ndikukhala kolimba kumapangitsa kukhala kosankha zodzikongoletsera. Chitsulocho chimapangidwa ndi cholumikizira chapamwamba kwambiri kuti apange chodzikongoletsera cholimba, cholimba komanso chokulirapo.
Platinamu, palladium kapena mphete zagolide zimatha kukanda, kupindika komanso kupindika mosavuta. Mphete za Tungsten sizigwada ndipo zimangokhala zowoneka bwino kwambiri ngati tsiku lomwe mudagula koyamba. Tungsten ndichitsulo cholimba komanso cholimba. Mutha kumva khalidweli polemera kwambiri mu tungsten. Mukaphatikiza kulemera kolimba komanso kupukutira kosatha kwa tungsten limodzi mu mphete imodzi, mumapanga chizindikiro chabwino cha chikondi chanu ndi kudzipereka kwanu.
Zambiri Zokhudza Tungsten:
Chizindikiro Cha Mankhwala: W
Nambala ya Atomiki: 74
Kusungunuka: Madigiri 10,220 Fahrenheit (5,660 madigiri Celsius)
Kuchulukitsitsa: ma ola 11.1 pa mainchesi imodzi (19.25 g / cm)
Isotopes: Isotopu Zachilengedwe Zisanu (pafupifupi isotopu yokumba makumi awiri ndi chimodzi)
Dzina Loyambira: Liwu loti "tungsten" limachokera ku mawu achiSweden akuti tung ndi sten, kutanthauza "mwala waukulu"
Njira Yopangira:
Tungsten ufa amadzazidwa mu mphete zolimba zachitsulo pogwiritsa ntchito njira yotchedwa sintering. Makina osindikizira mwamphamvu amanyamula ufa mu mphete yopanda kanthu. Mpheteyo imatenthedwa m'ng'anjo ya 2,200 degrees Fahrenheit (1,200 degrees Celsius). Magulu achikwati a tungsten ali okonzeka kuchita sintering. Njira yogwiritsira ntchito sintering imagwiritsidwa ntchito. Izi zimaphatikizapo kupititsa mphamvu yamagetsi molunjika pa mphete iliyonse. Pakuchulukirachulukira, mpheteyo imawotcha mpaka 5,600 madigiri Fahrenheit (3,100 madigiri Celsius), ndikulowa mphete yolimba pomwe ufa umafinya.
Kenako mpheteyo amaipanga ndi kuipukuta pogwiritsa ntchito zida za diamondi. Kwa mphete zokhala ndi siliva, golide, palladium, platinamu kapena zolowetsa magane, zida za diamondi zimakumba njira pakati pa mpheteyo. Chitsulo chamtengo wapatali chimakulungidwa mu mphete pansi pa kupanikizika ndikukonzanso.
Mphete za Tungsten motsutsana Tungsten Carbide mphete?
Pali kusiyana kwakukulu pakati pa mphete ya tungsten ndi mphete ya tungsten carbide. Tungsten mu mawonekedwe ake opangira ndi chitsulo chofiirira chomwe chimakhala chowuma komanso chovuta kugwira nawo ntchito. Chitsulo chachitsulo chimapanga ndikuchigaya kukhala ufa ndikuphatikizira ndi zinthu za kaboni ndi ena. Zonsezi ndizopanikizika limodzi kuti apange tungsten carbide. Kawirikawiri simudzapeza mphete ya tungsten yoyera, koma ilipo. Mphete za Tungsten carbide ndizolimba komanso zosagwira kuposa mphete ina iliyonse.
Chimodzi mwazinthu zazikulu kwambiri za mphete ya tungsten carbide ndikumakana. Pali zinthu zochepa chabe padzikoli zomwe zingakande mphete ya tungsten monga daimondi kapena china chovuta kufanana.
Aliyense wa tungsten mphete athu ndi chitsimikizo kuposa kale lonse la moyo. Chilichonse chikachitika ku mphete yanu, ingotidziwitsani ndipo tidzasamalira.
Kodi mphete zanu za tungsten zili ndi cobalt?
Ayi sichoncho! Pali mphete zambiri za tungsten pamsika zomwe zimakhala ndi cobalt. Tilibe cobalt m'mphete zathu. Cobalt ndi chotchipa chotchipa ogulitsa ena ambiri amagwiritsa ntchito kutulutsa mphete za tungsten. Cobalt mkati mwa mphete zawo imagwirizana ndimatumbo achilengedwe ndipo idzawononga, ipangitsa mphete yako kukhala imvi ndikusiya zipsera zofiirira kapena zobiriwira chala chanu. Mutha kupewa izi pogula imodzi tungsten carbide mphete zomwe mulibe cobalt.
