Xav txog yam muaj lub nplhaib uas yuav tsis khawb thiab yuav nyob zoo nkauj ib yam li hnub koj nyuam qhuav yuav nws.
Lub ntsej muag tawv yog lub phom ntev ruaj khov cov xim txho hlau ua rau lub ntsej muag me me ntawm lub ntiaj teb ua kaub puab (ncig 1/20 ooj haujlwm ntawm cov pob zeb). Tungsten tsis tshwm sim los ua cov hlau ntshiab hauv qhov. Nws yog ib txwm koom ua ke nrog kev sib txuas nrog lwm yam ntsiab lus. Lub siab khawb tsis kam thiab cov kav ntev ua rau nws zoo tshaj plaws xaiv rau cov hniav nyiaj hniav kub. Cov hlau yog siv nrog lub npov nickel siab dua los tsim ib qho nyuaj, ruaj khov thiab khawb qhov tawv ntawm cov hniav nyiaj hniav kub.
Platinum, palladium los yog kub ib ncig muaj peev xwm yooj yim khawb, kaus hniav thiab khoov. Tungsten rings tsis khoov thiab yuav nyob twj ywm saib raws nraim li qhov zoo nkauj txij li hnub koj tau yuav nws thawj zaug. Tungsten yog cov hlau uas tawv thiab hnyav. Koj tuaj yeem hnov qhov zoo hauv qhov hnyav hnyav hauv tungsten. Thaum koj muab cov khoom sib xyaw xim hnyav thiab xim ruaj khov ntawm tungsten ua ke hauv ib lub nplhaib, koj tsim lub cim zoo tshaj plaws ntawm koj txoj kev hlub thiab kev cog lus.
Cov Lus Qhia Txog Tungsten:
Tus Qauv Cim Tshuaj: W
Tus Npauj Laim: 74
Melting Point: 10,220 degrees Fahrenheit (5,660 degrees Celsius)
Qhov ceev: 11.1 ooj ib cubic nti (19.25 g / cm)
Isotopes: Tsib Isotopes Ntuj (ib puag ncig nees nkaum ib isotopes dag)
Lub Npe Keeb Kwm: Lo lus "tungsten" los ntawm cov lus Swedish tung thiab sten, txhais tau tias "pob zeb hnyav"
Cov Txheej Txheem Txheej Txheem:
Tungsten hmoov yog ntim rau hauv cov hlau sib dhos siv cov txheej txheem hu ua sintering. Cov xovxwm khov kho ntim cov hmoov kom txav mus rau hauv lub nplhaib. Lub nplhaib yog rhuab hauv qhov cub hluav taws xob ntawm 2,200 degrees Fahrenheit (1,200 degrees Celsius). Lub tungsten kab tshoob bands tau npaj txhij rau kev ua txhaum. Cov txheej txheem sintering ncaj qha yog siv. Qhov no cuam tshuam nrog kev hla lub tshuab hluav taws xob ncaj qha los ntawm txhua lub nplhaib. Raws li qhov tam sim no nce, lub nplhaib siab txog 5,600 degrees Fahrenheit (3,100 degrees Celsius), shrinking mus rau hauv lub nplhaib muaj zog raws li cov hmoov sau.
Lub nplhaib puab tau puab thiab polished siv cov cuab yeej siv pob zeb diamond. Rau cov nplhaib nrog nyiaj, kub, palladium, platinum lossis mokume gane inlays, pob zeb diamond cuab yeej khawb ib channel mus rau hauv nruab nrab ntawm lub nplhaib. Cov hlau uas muaj nqi yog inlaid rau hauv lub nplhaib hauv qab siab thiab rov ua haujlwm dua.
Tungsten Rings Vs Tungsten Carbide Rings?
Muaj qhov sib txawv ntawm lub nplhaib tungsten thiab lub nplhaib tungsten carbide. Tungsten hauv nws daim ntawv nyoos yog grey hlau uas yog nkig thiab nyuaj ua haujlwm nrog. Lub grey hlau forged los ntawm sib tsoo nws mus rau hauv cov hmoov thiab txuas nws nrog carbon ntsiab thiab lwm tus. Cov no yog txhua qhov suav ua ke los ua tungsten carbide. Tsis tshua muaj koj yuav pom lub nplhaib tungsten ntshiab, tab sis lawv muaj nyob. Tungsten carbide rings muaj zog dua thiab ntau khawb tiv dua lwm lub nplhaib.
Ib qho ntawm cov yeeb yam zoo tshaj plaws ntawm lub nplhaib tungsten carbide yog nws khawb tsis kam. Tsuas muaj qee yam ntawm lub ntiaj teb no uas tuaj yeem khawb cov nplhaib tungsten xws li lub pob zeb diamond lossis ib yam dab tsi ntawm cov tawv tawv sib npaug.
Txhua ntawm peb lub nplhaib tungsten tuaj nrog lub neej tsis muaj qhov xav tau tas sim neej. Yuav tsum muaj dab tsi tshwm sim rau koj lub nplhaib, tsuas yog qhia rau peb paub thiab peb yuav saib xyuas nws.
Koj lub tungsten rings puas muaj cobalt?
Tsis yog! Muaj ntau ntau lub tungsten carbide rings hauv kev ua lag luam uas muaj cov cobalt. Peb tsis muaj cobalt hauv peb cov nplhaib. Cobalt yog qhov pheej yig dua ntau lwm cov chaw muag khoom siv los tsim cov tungsten rings. Lub cobalt hauv lawv cov ntiv nplhaib cuam tshuam nrog lub cev tso tawm lub cev thiab yuav tarnish, tig koj lub nplhaib kom lub ntsej muag tsis xim thiab tawm xim av lossis ntsuab lo rau ntawm koj tus ntiv tes. Koj tuaj yeem zam qhov no los ntawm kev yuav khoom ib qho peb lub tungsten carbide rings uas tsis muaj cov cobalt.
