Koj puas tau hnov ​​txog lub twj tso kua mis silicon carbide slurry? Vim li cas nws thiaj li 'tom rau ntawm cov pob txha tawv'?

Hauv kev tsim khoom hauv Hoobkas, yeej ib txwm muaj qee cov kua dej uas "nyuaj rau kev tswj" - xws li cov ntxhia sib xyaw nrog cov khoom me me, cov dej khib nyiab nrog cov av qias neeg, cov "slurries" uas ntxhib thiab av uas cov twj dej ib txwm tuaj yeem hnav tawm tom qab tsuas yog ob peb lub twj. Lub sijhawm no, nws yog qhov tsim nyog los vam khom cov "neeg ua si hardcore" tshwj xeeb -silicon carbide slurry twj tso kua mis– mus rau theem.
Tej zaum ib txhia neeg yuav nug tias, lub twj tso kua dej puas yog lub twj tso kua dej rau kev rho cov kua dej xwb? Qhov txawv ntawm kev ntxiv peb lo lus 'silicon carbide' yog dab tsi? Qhov tseeb, qhov tseem ceeb nyob hauv nws cov khoom "lub plawv" - cov khoom ntws, xws li lub cev twj tso kua dej, impellers, thiab lwm yam khoom uas kov ncaj qha rau cov kua dej, ntau yam uas ua los ntawm cov khoom siv silicon carbide.
Silicon carbide yog dab tsi? Hais yooj yim xwb, nws yog ib yam khoom siv ceramic tshwj xeeb uas tawv thiab tiv taus kev hnav, nrog rau qhov nyuaj thib ob tsuas yog pob zeb diamond, thiab tiv taus qhov kub siab thiab xeb. Txawm tias thaum ntsib nrog cov slag slurry nrog cov khoom ntse, nws tuaj yeem "tiv taus kev hnav thiab xeb". Cov khoom siv overcurrent ntawm cov twj tso kua dej ib txwm yog ua los ntawm hlau. Thaum ntsib cov khoom siv coarse slurry, lawv yuav raug zom sai sai ntawm qhov av thiab yuav tsum tau hloov sai sai; Cov khoom siv overcurrent ua los ntawm silicon carbide zoo li "lub tsho tiv thaiv mos txwv" ntsia rau ntawm cov twj tso kua mis, uas tuaj yeem ua rau lawv lub neej ua haujlwm ntev dua thiab txo qhov teeb meem ntawm kev saib xyuas thiab hloov pauv ntau zaus.

Txawm li cas los xij, lub twj tso kua silicon carbide slurry tsis yog ib yam dab tsi uas yuav tsum siv yooj yim, nws yog tsim raws li tus cwj pwm ntawm cov slurry. Piv txwv li, yog tias qee cov slag slurry yog ntxhib, nws yog qhov tsim nyog los ua kom txoj kev ntws tuab dua thiab tsim cov qauv kom du dua, yog li cov khoom me me tuaj yeem hla mus tau yooj yim yam tsis muaj kev cuam tshuam lub twj tso kua mis; Qee cov slag slurry yog corrosive, yog li kev kho mob tshwj xeeb yuav raug siv rau ntawm qhov chaw ntawm silicon carbide kom txhim kho nws txoj kev tiv thaiv corrosion.
Niaj hnub nim no, txawm tias nws yog kev thauj cov slurry thaum lub sijhawm khawb av, kev ua cov tshauv ya hauv cov chaw tsim hluav taws xob, lossis kev thauj cov slurry corrosive hauv kev lag luam tshuaj lom neeg, daim duab ntawm silicon carbide slurry twj tso kua mis tuaj yeem pom. Nws tsis yooj yim li cov twj tso kua mis dej ib txwm muaj, thiab tuaj yeem ua haujlwm ruaj khov hauv cov xwm txheej ua haujlwm hnyav no, pab cov chaw tsim khoom txo lub sijhawm tsis ua haujlwm thiab txo cov nqi tsim khoom.
Hauv kev tshuaj xyuas zaum kawg, qhov zoo ntawm cov twj tso kua nplaum silicon carbide yog nyob rau hauv "kev sib xyaw ua ke muaj zog" ntawm cov ntaub ntawv thiab kev tsim - siv cov khoom siv tiv taus thiab tiv taus corrosion ntawm silicon carbide los daws qhov teeb meem ntawm "tsis hnav" rau cov twj tso kua nplaum ib txwm muaj, ua rau kev thauj mus los ntawm cov slurry nyuaj dua thiab tsis txhawj xeeb. Qhov ntawd kuj yog vim li cas nws tau dhau los ua "tus pab cuam" tseem ceeb hauv ntau qhov xwm txheej kev lag luam uas xav tau "kev ua haujlwm nyuaj".
