Cov Zoo thiab Cov Tsis Zoo ntawm Tungsten Hlau rau Cov Khoom Siv Hnyav
Tungsten, paub los ntawm nws lub cim tshuaj W thiab atomic number 74, yog ib qho ntawm cov hlau tawv tshaj plaws thiab tiv taus cua sov tshaj plaws pom muaj nyob hauv lub ntiaj teb. Nws kuj tseem hu ua wolfram. Hauv kev lag luam, tshwj xeeb tshaj yog hauv kev tsim kho khoom siv hnyav, tungsten pom ntau yam kev siv vim nws cov khoom tshwj xeeb. Txawm hais tias nws muaj ntau yam zoo, tungsten kuj muaj nws qhov tsis zoo. Tsab xov xwm no yuav piav qhia txog qhov zoo thiab qhov tsis zoo ntawm tungsten hlau thaum siv rau hauv cov khoom siv hnyav.
Cov txiaj ntsig ntawm Tungsten Hlau
1. Lub zog thiab kev ruaj khov zoo kawg
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm tungsten yog nws lub zog. Tungsten muaj qhov kub yaj ntawm kwv yees li 3.422 degrees Celsius, qhov siab tshaj plaws ntawm txhua yam hlau. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev tiv taus kub siab, xws li hauv cov khoom siv hnyav ua haujlwm hauv qab qhov xwm txheej hnyav lossis hauv cov khoom siv cav uas muaj kev sib txhuam siab.
Hauv cov khoom siv hnyav, lub zog no tso cai rau tungsten siv rau hauv cov khoom uas yuav tsum tiv taus qhov siab thiab cov khoom hnyav, xws li cov cuab yeej txiav lossis cov laum. Qhov zoo no tsis yog tsuas yog ua kom muaj kev ua haujlwm zoo xwb tab sis kuj ua rau lub neej ntawm cov khoom ntev dua, txo qhov xav tau kev saib xyuas ntau zaus.
2. Kev Ceev Ceev
Tungsten muaj qhov ceev siab, kwv yees li 19,3 grams ib cubic centimeter, yuav luag zoo ib yam li kub. Hauv kev siv, qhov ceev no muaj qhov zoo hauv kev ruaj khov thiab txuag qhov chaw. Piv txwv li, hauv cov khoom siv hnyav xws li excavators lossis bulldozers, tungsten reciprocating tuaj yeem siv los tsim qhov chaw qis dua ntawm lub ntiajteb txawj nqus yam tsis ntxiv qhov ntim tseem ceeb, txhim kho cov khoom siv ruaj khov thaum lub sijhawm ua haujlwm.
3. Tiv taus xeb
Tungsten muaj kev tiv thaiv zoo heev rau kev xeb thiab oxidation, tshwj xeeb tshaj yog thaum kub siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv qhov chaw ua haujlwm corrosive lossis hnyav heev. Hauv cov khoom siv hnyav, cov khoom tungsten tuaj yeem siv tau ntev dua thaum raug rau cov khoom ib puag ncig hnyav, xws li dej ntsev, cov tshuaj lom neeg hnyav, lossis cov huab cua noo siab.
4. Kev Nyuaj Siab Siab
Qhov tawv ntawm tungsten kuj ua rau nws tsim nyog rau cov khoom siv hnyav. Nws qhov tawv yog siab dua li lwm yam hlau, xws li hlau. Qhov tawv no tso cai rau tungsten siv rau hauv cov khoom uas xav tau kev tiv thaiv kev hloov pauv, xws li hauv kev tsim cov khoom siv tshuab thiab cov cuab yeej uas koom nrog kev tuav cov khoom hnyav.
Cov Kev Tsis Zoo ntawm Tungsten Hlau
1. Tus nqi kim heev
Ib qho ntawm cov teeb meem tseem ceeb tshaj plaws ntawm tungsten yog nws tus nqi siab. Nws cov txheej txheem khawb av thiab ua cov txheej txheem nyuaj, nrog rau cov khoom khaws cia tsawg, ua rau tungsten yog cov khoom siv kim heev hauv kev ua lag luam. Qhov no tuaj yeem ua rau muaj kev cov nyom loj hauv kev lag luam khoom siv hnyav, tshwj xeeb tshaj yog thaum nyiaj txiag yog qhov tseem ceeb. Yog li ntawd, kev siv tungsten feem ntau txwv rau cov khoom lossis cov khoom uas xav tau cov hlau cov yam ntxwv tshwj xeeb.
2. Kev nyuaj hauv kev ua tiav
Tungsten yog ib hom hlau uas tawv heev, thiab qhov tawv no kuj ua rau muaj kev cov nyom hauv kev siv tshuab. Kev txiav, kev tsim, thiab kev vuam tungsten xav tau cov khoom siv tshwj xeeb thiab cov txheej txheem nyuaj dua li lwm yam hlau xws li hlau lossis txhuas. Qhov no tsis yog tsuas yog ua rau cov nqi tsim khoom ntau ntxiv xwb tab sis kuj xav tau cov neeg ua haujlwm txawj ntse ntau dua.
3. Kev lom
Txawm hais tias feem ntau tungsten yog ib qho hlau uas muaj kev nyab xeeb, qee hom tungsten compounds tuaj yeem ua rau tib neeg thiab tsiaj txhu lom. Qhov no yuav tsum tau ceev faj ntxiv thaum tuav thiab pov tseg, tshwj xeeb tshaj yog thaum lub sijhawm ua cov khoom hauv cov chaw tsim khoom lossis yog tias cov khoom uas muaj tungsten puas tsuaj thiab yuav tsum tau muab pov tseg.
4. Kev ua haujlwm ntawm qee qhov kub thiab txias
Txawm hais tias tungsten tiv taus kub heev, ntawm qee qhov kub, tshwj xeeb tshaj yog thaum ua ke nrog lwm cov ntaub ntawv, nws tuaj yeem ua rau muaj kev cuam tshuam. Piv txwv li, ntawm qhov kub siab tshaj 500 degrees Celsius, tungsten tuaj yeem tsim tungsten oxide, uas tuaj yeem cuam tshuam rau cov khoom ntawm cov khoom. Qhov no xav tau kev tsim qauv zoo thiab cov ntaub ntawv ntxiv thaum tungsten siv ntawm qhov kub siab heev.
5. Kev Ceev Hnyav
Txawm hais tias qhov ceev siab yog qhov zoo dua hauv kev ruaj khov, nws kuj tuaj yeem ua qhov tsis zoo hauv qee qhov kev siv. Nws qhov hnyav loj txhais tau tias kev thauj mus los thiab kev teeb tsa cov khoom tungsten xav tau cov khoom siv ntxiv thiab cov nqi. Qee zaum, nws qhov hnyav siab tuaj yeem ua teeb meem hauv cov qauv nrog kev txwv qhov hnyav lossis hauv cov khoom siv hnyav uas xav tau kev txav mus los sai thiab agile.
Cov Ntawv Thov Tungsten Hauv Cov Khoom Siv Hnyav
Txawm hais tias muaj qhov tsis zoo uas yuav tsum xav txog, ntau lub lag luam tseem xaiv tungsten vim nws cov txiaj ntsig zoo tshaj plaws. Qee qhov kev siv tungsten hauv cov khoom siv hnyav suav nrog:
– Cov Cuab Yeej Txiav thiab Cov Khoom Siv Drilling: Hauv kev tsim kho thiab kev lag luam mining, tungsten carbide feem ntau yog siv los ua cov khoom siv rau cov laum me me, cov cuab yeej txiav, thiab cov khawb. Nws txoj kev tiv taus cua sov thiab kev hnav ua rau nws zoo dua hauv cov ntawv thov uas cuam tshuam nrog kev drilling lossis txiav cov khoom tawv.
– Cov Khoom Siv Sib Npaug Thiab Qhov Hnyav: Hauv cov tshuab hnyav xws li cranes lossis forklifts, cov khoom siv tungsten yog siv los txhim kho qhov sib npaug thiab kev ruaj khov.
– Cov Cheebtsam Cav: Qee cov khoom siv cav uas muaj kev kub siab thiab kub siab siv tungsten rau lub neej ntev thiab kev ua haujlwm zoo tshaj plaws.
