Hauv cov teb kev lag luam xws li kev khawb av, metallurgy, thiab fais fab, cov twj tso kua mis slurry yog cov khoom siv tseem ceeb rau kev thauj cov khoom siv hnav thiab cov khoom siv corrosive heev. Txawm hais tias cov twj tso kua mis hlau ib txwm muaj lub zog siab, lawv feem ntau ntsib teeb meem ntawm kev hnav sai thiab lub neej luv luv thaum ntsib cov xwm txheej ua haujlwm nyuaj. Nyob rau hauv xyoo tas los no, kev siv cov khoom siv tshiab -silicon carbide ceramics- tau coj qhov ruaj khov thiab ua haujlwm tau zoo ntawm cov twj tso kua mis mus rau ib theem tshiab.
1, Silicon carbide ceramics: los ntawm "cov hniav lag luam" mus rau cov khoom siv lub cev twj tso kua mis
Silicon carbide (SiC) yog lub npe hu ua "cov hniav lag luam", nrog rau qhov nyuaj thib ob tsuas yog pob zeb diamond tab sis sib dua li cov hlau. Cov khoom siv no tau siv thawj zaug rau cov log sib tsoo thiab cov cuab yeej txiav. Tom qab ntawd, cov kws tshawb fawb tau pom tias nws qhov kev tiv thaiv kev hnav thiab kev ruaj khov tshuaj lom neeg tuaj yeem daws cov teeb meem mob ntawm cov twj tso kua mis slurry:
Hnav tsis kam thiab tiv taus corrosion: Nws qhov nyuaj yog qhov thib ob tsuas yog pob zeb diamond, thiab nws tuaj yeem yooj yim tiv taus kev yaig ntawm cov xov xwm uas muaj xuab zeb, xuab zeb, thiab cov khoom me me;
Kev tiv thaiv xeb ntuj: Nws muaj zog tiv taus cov kua qaub muaj zog thiab lwm yam kev daws teeb meem, zam kev teeb meem xeb ntawm cov twj tso kua hlau;
Tsim qauv sib dua: Qhov ceev tsuas yog ib feem peb ntawm cov hlau, txo cov khoom siv thauj khoom thiab kev siv zog.
2, Peb qhov zoo ntawm cov twj siv silicon carbide ceramic
1. Ntev lub neej ntev dua ntau zaus
Cov twj tso kua hlau ib txwm yuav xav tau hloov cov impellers thiab cov casings twj tso kua mis hauv ntau lub hlis thaum thauj cov slurries abrasive, thaum cov ntaub ntawv silicon carbide tuaj yeem ua haujlwm ruaj khov rau ntau xyoo, txo qhov zaus ntawm kev poob haujlwm thiab kev txij nkawm.
2. Txo cov nqi kho
Vim tias txo qhov hnav thiab tsim kua muag, lub voj voog hloov pauv ntawm cov khoom siv tau ntev dua, thiab cov khoom siv ceramic tsis tas yuav tsum tau kho cov xeb ntau zaus, ua rau txo qis cov nqi kho tag nrho.
3. Kev ua haujlwm ruaj khov dua
Qhov du ntawm cov khoom siv ceramics yog qhov siab heev, thiab kev siv mus sij hawm ntev tsis yooj yim ua rau muaj qhov lossis kev hloov pauv. Nws ib txwm tswj txoj kev thauj mus los nruab nrab kom tsis txhob muaj kev puas tsuaj.
3、 Cov xwm txheej twg xav tau cov twj siv silicon carbide ceramic ntau dua?
Cov xwm txheej hnyav heev: xws li kev thauj mus los ntawm cov tailings mining, kev kho cov thee slurry hauv cov nroj tsuag ntxuav thee
Ib puag ncig muaj zog corrosive: kev thauj mus los ntawm cov kua qaub muaj zog thiab lwm yam xov xwm hauv kev lag luam tshuaj lom neeg, kev ncig ntawm desulfurization slurry
Qhov yuav tsum tau ua kom huv si: Cov yam ntxwv inert ntawm cov khoom siv ceramic tuaj yeem zam kev sib kis ntawm cov hlau ion ntawm cov khoom nruab nrab
4, Cov Lus Ceeb Toom rau Kev Xaiv
Txawm hais tias cov twj siv silicon carbide ceramic muaj kev ua tau zoo heev, lawv yuav tsum tau phim raws li cov xwm txheej ua haujlwm tshwj xeeb:
Nws raug pom zoo kom xaiv cov tshuaj tiv thaiv sintered silicon carbide (nrog rau kev cuam tshuam muaj zog dua) ua cov khoom me me ultrafine
Yuav tsum tau ua tib zoo saib xyuas cov ntaub ntawv sealing thiab kev tsim qauv hauv qhov chaw kub siab.
Tsis txhob muaj kev sib tsoo loj thaum lub sijhawm teeb tsa (cov khoom siv ceramic yog brittle dua li hlau)
xaus lus
Raws li "tus neeg saib xyuas uas tsis yooj yim hnav" hauv kev lag luam, cov twj tso kua mis silicon carbide ceramic slurry txhawb kev txhim kho ntawm cov lag luam ib txwm muaj mus rau kev ua haujlwm siab thiab kev tiv thaiv ib puag ncig nrog lub neej ua haujlwm ntev dua thiab kev siv hluav taws xob tsawg dua. Rau cov lag luam, kev xaiv hom twj tso kua mis uas tsis yooj yim hnav tsis yog tsuas yog txhais tau tias txuag cov nqi khoom siv, tab sis kuj yog qhov lav tseem ceeb rau kev ua haujlwm txuas ntxiv thiab kev nyab xeeb.
Shandong Zhongpengtau koom nrog tob hauv kev ua haujlwm ntawm cov ntaub ntawv hnav-resistant rau ntau tshaj kaum xyoo, thiab txaus siab los muab cov kev daws teeb meem mus sij hawm ntev rau koj cov teeb meem kev thauj mus los hauv kev lag luam nrog cov thev naus laus zis tshiab.
