Kev xaiv cov khoom siv dej tank rau hluav taws xob cua sov raj

Rau cov ntaub ntawv siv los tsim hluav taws xob cua sov raj, cov tuam ntxhab tam sim no yuav xaiv cov khoom lag luam tus qauv uas muaj nyob hauv khw. Txawm li cas los xij, muaj lwm yam tshwj xeeb uas yuav tsum tau siv los ua cov khoom siv rau cov kav dej cua sov hauv cov kav dej, feem ntau yog siv cov kav dej stainless hlau thiab magnesium hmoov ua piv txwv.

1 stainless hlau yeeb nkab

Kev tiv thaiv corrosion ntawm hluav taws xob cua sov raj yuav tsum ua tau raws li qhov yuav tsum tau ua. Nyob rau hauv cov nqe lus ntawm kev tswj kav kav dej, fluorescence spectroscopy tsom xam ntawm cov ntaub ntawv tuaj yeem txiav txim siab rau cov kav dej. Qhov tseem ceeb tshaj, nws yuav tsum muaj qhov tsim nyog hardness thiab tensile lub zog, thiab tswj kev sib xws hauv txhua pawg ntawm cov ntaub ntawv. Lub zog tensile tsis raug tuaj yeem ua rau microcracks thaum lub sijhawm khoov thiab tsim cov txheej txheem hluav taws xob cua sov, uas tuaj yeem ua rau tsis ua haujlwm, corrosion, lossis tawg tom qab siv sijhawm. Rau cov ntaub ntawv, cov ntaub ntawv nrog qhov sib txawv hardness tuaj yeem ua rau qhov tsis sib xws thaum lub sij hawm cov raj xa dej sib txuas, ua rau muaj qhov yuam kev ntev hauv cov kav hluav taws xob cua sov thiab nce cov nqi seem.

2 magnesium hmoov

Magnesium hmoov, raws li kev rwb thaiv tsev thiab cov khoom siv thermal conductive hauv hluav taws xob cua sov, muaj qhov tseem ceeb. Txawm hais tias lub tshuab hluav taws xob cua sov tsuas yog dej kub xwb, qhov kub thiab txias tsis yog siab npaum li cov hlab ntsha qhuav, thiab tsis muaj kev txwv nruj rau magnesium hmoov. Txawm li cas los xij, txhawm rau kom ntseeg tau tias lub neej ua haujlwm ntev ntawm cov kav hluav taws xob cua sov, nws yog ib qho tsim nyog yuav tsum tswj qee yam tseem ceeb. Piv txwv li, nyob rau hauv cov nqe lus ntawm kev tswj pub, nws yog ib qhov tsim nyog los soj ntsuam cov tshuaj muaj pes tsawg leeg ntawm txhua batch ntawm cov ntaub ntawv los xyuas kom meej tias magnesium ntsiab lus mus txog 96% los yog ntau tshaj, thiab nruj me ntsis tswj cov teeb meem xws li boron thiab sulfur nyob rau hauv cov khoom xyaw. Vim tias qhov kub tsis kam ntawm boron, qhov kub tsis kam ntawm magnesium oxide thaum siv hluav taws xob thiab siv yuav txo qis, thiab nyob rau hauv cov xwm txheej hnyav, nws tuaj yeem ua rau to. Sulfur yog corrosive, thiab corrosion ntawm cov hlau tsis kam yuav txo cov kev pab cuam lub neej ntawm cov khoom.

welded cev

Kev sib txuas ntawm hluav taws xob cua sov raj yog tus yuam sij rau kev tswj cov txheej txheem tsim hluav taws xob cua sov raj. Lub tshuab hluav taws xob ua kom muaj ntau qhov ntau yog welded, yog li nws tseem ceeb heev kom ntseeg tau tias vuam zoo. Qee qhov chaw vuam yuav zoo li du rau ntawm qhov muag liab qab, tab sis qhov tseeb, muaj micropores. Zuag qhia tag nrho, tej zaum yuav muaj qee qhov tsis zoo, xws li tsis muaj qhov tseeb vuam, tsis tsim nyog vuam sib tshooj, thiab lwm yam, uas cuam tshuam rau lub zog ntawm vuam seam. Hauv kev tswj cov txheej txheem, eddy cov cuab yeej ntsuas tam sim no yog siv los tshuaj xyuas qhov vuam zoo, thiab kev tshuaj xyuas metallographic ua rau ntawm qhov vuam los txiav txim siab lawv cov mob.

Resistance hlau

Yog tias qhov kev faib tawm ntawm cov xaim hluav taws xob nrog cov hluav taws xob cua sov hauv lub tshuab hluav taws xob cua sov yog qhov tsis sib xws, ces qhov kub thiab txias ntawm cov cua sov raj tsis sib xws. Yog tias ua txhaum cai, nws yuav ua rau txo qis hauv kev ua haujlwm ntawm lub tshuab hluav taws xob cua sov, thiab txawm tias hluav taws xob tsis ua haujlwm. Yog li ntawd, los ntawm kev siv cov khoom siv X-ray fluoroscopy, qhov kev sib cais ntawm cov kab hauv nruab nrab tuaj yeem raug soj ntsuam rau kev txiav txim.
