Kev Siv Tshuab Laser Cladding: Kev Tsim Kho Tshiab Ntsuab uas Muab Cov Khoom Siv Petrochemical nrog "High-Performance Armor"
Hauv kev lag luam petrochemical, ib qho kev lag luam tseem ceeb rau kev ruaj ntseg lub zog hauv tebchaws thiab lub neej ntawm cov lag luam yooj yim, kev ua haujlwm ntev thiab ruaj khov ntawm cov khoom siv tsim khoom yog txoj sia rau kev ua haujlwm zoo thiab muaj kev nyab xeeb. Txawm li cas los xij, qhov chaw ua haujlwm hnyav heev - kub siab, siab siab, xeb hnyav, thiab kev puas tsuaj ntawm cov xov xwm - tas li sim qhov ruaj khov ntawm cov khoom siv tseem ceeb. Twj tso kua mis, cov li qub, cov kav dej, cov reactors, thiab lwm yam khoom ua haujlwm ua "cov hlab ntsha" thiab "lub plawv" ntawm cov txheej txheem tsim khoom, thiab kev ncaj ncees ntawm lawv cov nto sab hauv ncaj qha txiav txim siab lub neej ua haujlwm thiab kev ntseeg siab ntawm tag nrho chav tsev. Cov kev daws teeb meem ib txwm muaj, xws li siv cov ntaub ntawv ua tau zoo thoob plaws lossis xav tau lub sijhawm tsis ua haujlwm rau kev hloov khoom, tsis yog tsuas yog kim xwb tab sis kuj siv sijhawm ntau. Tawm tsam qhov keeb kwm yav dhau los no, laser cladding technology, ua ib qho kev tsim kho nto siab heev thiab kev tsim kho dua tshiab, tab tom muab cov kev daws teeb meem tshiab rau kev txuas lub neej thiab ua kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm cov khoom siv petrochemical nrog nws cov kev ua tau zoo tshaj plaws.
I. Cov Kev Sib Tw Loj: "Qhov Mob Uas Muaj Los Ntawm" ntawm Cov Khoom Siv Petrochemical
Cov khoom siv roj av ntsib kev puas tsuaj feem ntau los ntawm kev tawm tsam tshuaj lom neeg thiab lub cev los ntawm cov xov xwm sab hauv:
Kev Tshuaj Lom ZemThaum ua cov roj av lossis cov khoom siv tshuaj lom neeg uas muaj cov tshuaj corrosive xws li sulfur, chlorine, acid, thiab alkali, cov hlau substrate ntawm cov khoom siv (feem ntau yog carbon steel lossis stainless steel) tuaj yeem raug kev xeb sib xws, pitting, thiab intergranular corrosion, ua rau phab ntsa nyias, perforation, thiab txawm tias tsis ua haujlwm.
Kev Hnav Khaub Ncaws: Cov dej ntws ceev ceev ntawm cov khoom me me ntawm cov catalyst, slurry, pa dej, thiab lwm yam xov xwm txuas ntxiv ua rau cov kav dej sib tsoo thiab hnav cov kav dej, cov kav dej ntws, cov qhov rooj kaw lub qhov rooj, thiab lwm yam khoom, ua rau cov khoom poob thiab cov qauv puas tsuaj.
Kev Oxidation Kub Siab thiab Kev Nkees Thermal: Cov reactors thiab cov kav dej kub kub ua haujlwm nyob rau hauv qhov kub siab tas li, ua rau cov khoom siv hlau yooj yim rau oxidation thiab creep, thiab txawm tias thermal qaug zog tawg thaum lub sijhawm kub uas cuam tshuam nrog kev pib thiab kaw. Cov kev puas tsuaj no feem ntau ua rau cov khoom siv tseem ceeb tsis ua haujlwm ua ntej lub sijhawm, yuam kom cov tuam txhab feem ntau kaw rau kev kho. Txhua lub sijhawm tsis tau npaj tseg tuaj yeem ua rau muaj kev poob nyiaj txiag ntau lab yuan thiab ua rau muaj kev pheej hmoo kev nyab xeeb.
II. Cov thev naus laus zis tseem ceeb: Yuav ua li cas laser cladding tsim ib lub "lub cev uas tsis puas tsuaj"
Laser cladding yog ib qho thev naus laus zis tsim khoom ntxiv uas siv lub teeb laser muaj zog siab ua qhov chaw kub kom yaj cov hmoov hlau thiab ib txheej nyias nyias ntawm qhov chaw substrate, yog li tsim cov txheej txheem sib txuas ua ke zoo ntawm qhov chaw substrate. Lub hauv paus ntsiab lus ntawm nws daim ntawv thov hauv kev tiv thaiv cov khoom siv petrochemical tuaj yeem sau ua ke raws li hauv qab no:
1. Kev tswj lub zog kom meej: Lub zog ntawm lub teeb laser muaj zog heev, qhov kub thiab txias ceev heev, qhov nkag ntawm cua sov thiab thaj chaw cuam tshuam los ntawm cua sov rau lub substrate me me heev, thiab kev hloov pauv ntawm cov khoom ua haujlwm thiab kev ua haujlwm poob qis raug zam.
2. Cov Kev Zoo ntawm Kev Sib Txuas Hlau: Cov txheej cladding thiab cov khoom siv hauv paus yaj thiab sib kis mus rau ib leeg ntawm qhov kub siab, tsim cov hlau sib txuas muaj zog. Cov kev sib txuas no muaj zog dua li cov kev sib txuas tshuab uas ua tiav nrog cov txheej txheem ib txwm muaj xws li kev txau thiab electroplating, thiab cov txheej tsis yooj yim rau tev tawm.
3. Kev ywj pheej ntawm kev tsim cov khoom siv: Koj tuaj yeem "kho kom haum" raws li cov xwm txheej ua haujlwm tshwj xeeb thiab xaiv cov hmoov hlau uas tiv taus corrosion, hnav-resistant lossis kub-resistant (xws li nickel-based, cobalt-based, hlau-based alloys thiab hlau-ceramic composites) rau cladding kom ua tiav qhov kev sib xyaw ua ke zoo tshaj plaws ntawm "kev coj tus kheej matrix zoo heev thiab kev coj tus kheej muaj zog".
Rau cov khoom siv petrochemical, tshwj xeeb tshaj yog cov nplaim sab hauv ntawm cov kav dej thiab cov reactors, cov khoom siv laser cladding tshwj xeeb sab hauv feem ntau yog siv los ua kom tiav cov txheej txheem tsis siv neeg thiab sib xws hauv cov chaw nyuaj thiab kaw, kom ntseeg tau tias muaj cov txheej txheem zoo thiab tsis muaj qhov tsis xws luag.
III. Cov txiaj ntsig ntawm daim ntawv thov: txhaj tshuaj tshiab rau hauv cov khoom siv tseem ceeb
Kev siv cov thev naus laus zis laser cladding rau ntau yam khoom siv petrochemical tuaj yeem coj cov txiaj ntsig tam sim ntawd thiab mus sij hawm ntev:
Cov twj tso kua mis (cov twj tso kua mis centrifugal, cov twj tso kua mis reciprocating): Kev siv cov hlau cam khwb cia hlau chromium siab, tungsten carbide thiab lwm yam khoom siv uas tsis yooj yim hnav rau ntawm qhov chaw ntawm cov khoom ntws xws li cov twj tso kua mis thiab cov impellers tuaj yeem tiv taus kev yaig ntawm cov slurry thiab cov khoom me me, thiab txuas ntxiv lub sijhawm poob qis ntau zaus.
Cov li qub (cov li qub pob, cov li qub rooj vag, cov li qub ntiaj teb): Cov hlau nplaum uas muaj cobalt xws li Stellite raug muab tso rau ntawm qhov chaw kaw ntawm lub rooj zaum valve thiab lub plawv valve (pob) kom ntseeg tau tias nws tiv taus kev hnav thiab kev xeb zoo heev, tshem tawm cov dej xau sab hauv, thiab ua tiav kev kaw nruj.
Cov kab ke kav dej (cov kav dej ncaj, lub luj tshib, cov tees): Tshwj xeeb tshaj yog ntawm lub luj tshib uas yooj yim rau kev yaig, cladding nrog cov txheej tiv taus hnav thiab tiv taus corrosion tuaj yeem tiv thaiv tag nrho phab ntsa sab hauv, daws qhov teeb meem ntawm kev tawg ua ntej los ntawm cov nyhuv "skirting" hauv zos, thiab ua kom lub neej kav dej ntev dua 3-5 zaug.
Lub tshuab ua kom sov (lub cev ntawm lub lauj kaub, lub tshuab ua kom sov, cov khoom sab hauv): Phab ntsa sab hauv yog clad nrog ib txheej ntawm Hastelloy lossis 625 alloy uas tiv taus kub siab, carburization, thiab acid thiab alkali corrosion, zoo tiv taus kev yaig ntawm cov tshuaj tiv thaiv, tswj hwm qhov chaw ib puag ncig ntshiab, thiab xyuas kom meej cov khoom zoo.
IV. Dhau Kev Tiv Thaiv: Kev Dhia Mus Rau Hauv Tus Nqi Tag Nrho
Tus nqi ntawm cov thev naus laus zis laser cladding mus deb tshaj qhov "kho". Nws tseem yog ib qho kev tiv thaiv "active protection" thiab "remanufacturing" zoo heev, coj ntau yam kev txhim kho rau cov tuam txhab petrochemical:
Txuas ntxiv lub voj voog txij nkawm thiab xyuas kom meej tias kev ua haujlwm mus sij hawm ntev: Qhov kev txhim kho tseem ceeb hauv kev ntseeg siab ntawm cov khoom siv tau ua kom ntev lub voj voog kho dua tshiab los ntawm 1-2 xyoos dhau los mus rau 3-4 xyoos lossis ntev dua, uas ua tau raws li "kev nyab xeeb, ruaj khov, ntev, puv thiab zoo heev" kev ua haujlwm ntawm kev lag luam tshuaj niaj hnub.
Txo nqi, txhim kho kev ua haujlwm tau zoo, thiab kev txhim kho kom ruaj khov: Piv rau kev hloov cov khoom kim heev uas muaj cov hlau nplaum ntau tag nrho, cov laser cladding tsuas yog ua kom lub ntsej muag muaj zog xwb, txuag tau ntau dua 70% ntawm cov nqi khoom siv. Nws kuj tso cai rau kev rov ua dua cov khoom pov tseg, muab kev ua tau zoo dua li cov tshiab, raws li cov ntsiab cai ntawm kev lag luam ncig thiab kev txhim kho ntsuab.
Txhim kho cov teeb meem kev nyab xeeb: Tshem tawm cov kev phom sij zais cia ntawm cov xwm txheej loj xws li kev xau nruab nrab, hluav taws thiab tawg los ntawm kev nyias nyias ntawm cov khoom siv phab ntsa tuab thiab kev xeb perforation, thiab tsim kom muaj kev thaiv kev ruaj khov rau kev nyab xeeb kev tsim khoom.
Xaus lus
Cov thev naus laus zis laser cladding, nrog nws cov yam ntxwv digital, meej, thiab yoog tau, tab tom hloov pauv kev saib xyuas cov khoom siv hauv kev lag luam petrochemical. Nws nruab cov khoom siv tseem ceeb no nrog "kev ua haujlwm siab" uas tsim tshwj xeeb, ua rau lawv tuaj yeem tiv taus cov xwm txheej ua haujlwm nyuaj tshaj plaws. Nrog rau kev siv cov thev naus laus zis thiab kev ua kom zoo dua qub, laser cladding tau npaj los ua ib qho ntawm cov thev naus laus zis tseem ceeb uas ua kom muaj kev nyab xeeb, txo nqi, txhim kho kev ua haujlwm zoo, thiab kev txhim kho kom ruaj khov rau cov tuam txhab petrochemical, txhaj tshuaj muaj zog thev naus laus zis rau hauv kev ua haujlwm ruaj khov ntawm Tuam Tshoj lub zog thiab kev lag luam tshuaj lom neeg.
