Puas muaj qhov tsis zoo rau kev siv cov khoom siv raw, pheej yig graphite?
Pheej yiggraphite foob pob ua ntxaij nozzlesmuaj ntau impurities thiab purity ntawm graphite tsis siab. Cov impurities no yuav cuam tshuam rau cov conductivity, kub tsis kam thiab tshuaj stability ntawm graphite, thiab ua tsis zoo nyob rau hauv ib co kev lag luam daim ntaub ntawv.
Tsawg-zoo graphite muaj cov qauv tsis sib xws thiab muaj qhov ua rau tawg lossis tawg hauv qhov kub thiab txias ib puag ncig, cuam tshuam rau nws lub neej kev pabcuam.
Tsis zoo-zoo graphite foob pob ua ntxaij nozzles tsis tau ua zoo los yog kho, thiab lawv hnav tsis kam thiab oxidation kuj tsis zoo. Lawv nquag hnav lossis oxidation thaum siv, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias.
Thaum siv cov graphite pheej yig, cov txheej txheem tsim khoom yog qhov yooj yim, uas yuav ua rau muaj kev hloov pauv loj ntawm cov khoom, ua rau nws nyuaj rau kev ruaj ntseg zoo, cuam tshuam rau nws daim ntawv thov hauv precision teb.
Yuav ua li cas yog cov kab nrib pleb tshwm nyob rau hauvgraphite foob pob hluav taws nozzle?
1. Yog tias pom muaj kab nrib pleb, kev siv yuav tsum tau nres tam sim ntawd txhawm rau tiv thaiv kev nthuav dav ntxiv ntawm cov kab nrib pleb lossis ua rau lub nozzle tsis ua haujlwm thaum lub sijhawm ya.
Siv cov kev ntsuas tsis muaj kev puas tsuaj los xyuas qhov loj, qhov tob thiab kev faib tawm ntawm cov kab nrib pleb thiab ntsuas qhov kev puas tsuaj rau cov graphite nozzle.
Tshawb xyuas qhov zoo ntawm cov khoom siv graphite, nrog rau kev ua kom huv, kev ua haujlwm sib xws, thiab lwm yam, txhawm rau txiav txim siab seb cov kab nrib pleb yog tshwm sim los ntawm cov khoom tsis zoo.
2. Ntsuam xyuas seb puas muaj cov txheej txheem tsis xws luag hauv cov txheej txheem nozzle tsim, xws li tsis sib xws sintering, kev nyuaj siab concentration, thiab lwm yam.
Tshawb xyuas cov kev ua haujlwm ntawm lub cav, suav nrog seb puas muaj qhov ntsuas kub thiab siab tshaj qhov siab ntawm cov khoom siv nozzle, ua rau tawg.
3. Rau cov kab nrib pleb me me, koj tuaj yeem sim sau cov kab nrib pleb nrog cov ntaub ntawv kub kub refractory. Txoj kev no feem ntau tsuas yog kev daws teeb meem ib ntus xwb.
Yog tias cov kab nrib pleb loj lossis tob, nws raug nquahu kom hloov tag nrho graphite foob pob hluav taws nozzle lossis qhov puas. Kev kho yuav tsis rov qab ua qhov qub ntawm lub nozzle thiab muaj kev pheej hmoo ntau dua.
4. Cov khoom yuav tsum xaiv cov khoom siv high-purity thiab uniformly graphite cov ntaub ntawv los txo qhov tsis xws luag thiab kev ntxhov siab concentration hauv cov khoom.
Hauv kev tsim thiab tsim cov txheej txheem, txo qis kev ntxhov siab thiab siv cov txheej txheem tsim khoom txhim khu kev qha kom tsis txhob muaj qhov tsis xws luag hauv cov khoom.
Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua yuav tsum tau ua ntawm graphite foob pob ua ntxaij nozzles ua ntej thiab tom qab siv txhawm rau txhawm rau txheeb xyuas thiab daws cov kab nrib pleb lossis lwm yam kev puas tsuaj raws sijhawm.
Vim li cas graphite foob pob hluav taws nozzles yuav tsum tau ua los ntawm graphite?
1. Graphite muaj qhov siab tshaj plaws melting point ntawm tag nrho cov ntaub ntawv. Lub nozzle yuav raug kub heev thaum lub sijhawm ua haujlwm. Lub siab kub tsis kam ntawm graphite tuaj yeem nyob ruaj khov hauv qhov kub thiab txias.
2. Lub thermal expansion coefficient ntawm graphite foob pob ua ntxaij nozzles yog tsawg heev, thiab nws tsis yooj yim rau deform los yog tawg nyob rau hauv drastic kub hloov.
3. Graphite muaj cov thermal conductivity zoo, uas tuaj yeem tawg sai sai, txo cov cua sov hauv zos, thiab zam cov khoom siv hauv zos tsis ua haujlwm. Nws yog ib qho tseem ceeb heev kom muaj kev ruaj ntseg thiab lub neej ntawm lub nozzle.
4. Tom qab kev kho mob antioxidant los yog txheej txheej, nws cov kav ntev hauv qhov kub thiab txias oxidizing ib puag ncig tuaj yeem txhim kho tau zoo. Nws muaj corrosion kuj zoo rau ntau yam tshuaj.
5. Cov khoom siv tau yooj yim machined rau hauv cov duab complex, uas yog heev haum rau manufacturing cov khoom uas yuav tsum tau precision tsim
7. Piv nrog rau lwm cov khoom siv high-temperature resistant, tus nqi ntawm graphite kuj tsis tshua muaj nqi, yog li nws muaj qee qhov zoo ntawm cov nqi-zoo.
