Koj Paub Ntau npaum li cas txog Tungsten Carbide Powder?

Tungsten carbide yog lub npe hu ua ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws nyob rau hauv lub ntiaj teb no, thiab tib neeg paub zoo txog cov khoom siv no. Tab sis li cas txog tungsten carbide hmoov, cov khoom siv raw ntawm tungsten carbide khoom? Hauv tsab xov xwm no, peb yuav paub qee yam txog tungsten carbide hmoov.

Raws li cov khoom siv raw

Cov khoom siv tungsten carbide yog txhua yam ua los ntawm tungsten carbide hmoov. Hauv kev tsim khoom, qee cov hmoov yuav ntxiv rau cov hmoov tungsten carbide ua cov ntaub ntawv sib txuas kom sib xyaw cov tungsten carbide hais nruj heev. Nyob rau hauv qhov zoo tagnrho, qhov kev faib ua feem ntau dua ntawm tungsten carbide hmoov, qhov kev ua tau zoo ntawm tungsten carbide cov khoom yuav zoo dua. Tab sis qhov tseeb, ntshiab tungsten carbide yog tsis yooj yim sua. Qhov no yog vim li cas binder muaj. Lub npe ntawm qib ib txwm tuaj yeem qhia koj tus lej ntawm cov binders. Zoo li YG8, uas yog cov qib siv los tsim cov khoom siv tungsten carbide, muaj 8% ntawm cobalt hmoov. Ib qho nyiaj ntawm titanium, cobalt, lossis npib tsib xee tuaj yeem hloov pauv kev ua haujlwm ntawm tungsten carbide. Siv cobalt ua piv txwv, qhov zoo tshaj plaws thiab feem ntau feem ntau ntawm cobalt yog 3% -25%. Yog tias cov cobalt ntau dua 25%, tungsten carbide yuav mos vim muaj ntau cov binders. Qhov tungsten carbide no tsis tuaj yeem siv los tsim lwm yam cuab yeej. Yog tias tsawg dua 3%, cov khoom tungsten carbide nyuaj rau khi thiab cov khoom tungsten carbide tom qab sintering yuav nkig heev. Ib txhia ntawm koj tej zaum yuav tsis meej pem, vim li cas manufacturers hais cov tungsten carbide hmoov nrog binders yog tsim nrog 100% ntshiab raw cov ntaub ntawv? 100% raw cov ntaub ntawv ntshiab txhais tau hais tias peb cov ntaub ntawv raw tsis rov siv dua los ntawm lwm tus.

Ntau tus kws tshawb fawb tab tom sim nrhiav txoj hauv kev tsim khoom zoo dua los txo cov nqi ntawm cobalt, thaum tseem khaws cov kev ua yeeb yam zoo ntawm tungsten carbide.

Kev ua yeeb yam ntawm tungsten carbide hmoov

Tungsten carbide muaj ntau yam ntxwv, yog li nws tsis yooj yim rau kev xav tias tungsten carbide hmoov kuj muaj ntau yam zoo thiab cov yam ntxwv. Tungsten carbide hmoov tsis yog soluble, tab sis nws yog yaj hauv aqua regia. Yog li cov khoom tungsten carbide yeej ib txwm muaj tshuaj lom neeg ruaj khov. Tungsten carbide hmoov muaj qhov melting point ntawm ib ncig ntawm 2800 ℃ thiab lub boiling point ntawm ib ncig ntawm 6000 ℃. Yog li cobalt yooj yim yaj thaum tungsten carbide hmoov tseem nyob rau hauv qhov kub thiab txias.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
