Kev tu thiab tu ntawm Stainless Hlau Mesh: Phau Ntawv Qhia Txog Lub Neej

Kev teeb tsa ntawm lub siab - zoo stainless hlau screen yog ib qho tseem ceeb peev peev, tab sis nws cov kev ua tau zoo nyob rau lub sij hawm tag nrho yog nyob ntawm qhov nruj ntawm nws txoj kev tswj xyuas. Txawm hais tias stainless hlau muaj npe nrov rau nws cov kav ntev, nws tsis yog "haum thiab tsis nco qab" cov khoom. Hauv kev lag luam ib puag ncig, cov ntxaij vab tshaus raug cuam tshuam los ntawm cov neeg kho tshuab kev ntxhov siab, raug tshuaj lom neeg, thiab cov khoom sib xyaw ua ke uas tuaj yeem ua rau muaj tus mob hu ua "dig muag" lossis "pegging." Yog tsis muaj lub tswv yim zoo txog kev ua neej nyob, txawm tias tus nqi kim tshaj Qib 316L mesh yuav thaum kawg poob nws qhov permeability, ua rau muaj zog poob siab thiab muaj peev xwm ua tsis tiav.

Phau ntawv qhia 1,500 lo lus no ua haujlwm raws li phau ntawv qhia txog kev saib xyuas cov ntaub ntawv xov hlau. Peb yuav tshawb xyuas cov txheej txheem kev tshaj lij rau kev tu, cov tshuaj lom neeg cov logic tom qab passivation, thiab cov txheej txheem tshuaj xyuas siv los kwv yees qhov kawg ntawm lub vijtsam lub neej kev pabcuam. Los ntawm kev txav los ntawm kev kho reactive rau tus qauv kev saib xyuas, cov koom haum tuaj yeem txuas ntxiv lub neej ntawm lawv cov cuab yeej mesh, ua kom cov khoom zoo sib xws, thiab txo qis tag nrho cov tswv cuab.

Lub cev sib tw ntawm Particle Accumulation

"Qhov muag tsis pom kev" tshwm sim thaum cov khoom zoo, cov dej noo, los yog cov nplaum nplaum nplaum rau saum npoo ntawm cov xov hlau, zoo sealing lub apertures thiab tiv thaiv cov dej ntws. Qhov no yog ib qho teeb meem tshwm sim hauv kev ua zaub mov thiab tshuaj lag luam uas cov roj thiab cov protein tuaj yeem tsim cov yeeb yaj kiab tawv ncauj. Yog tias sab laug tsis kho, qhov sib txuam no tsim qhov tsis sib xws ntawm kev faib tawm thoob plaws lub vijtsam, uas tuaj yeem ua rau lub mesh "lub hnab" los yog ncab, mus tas li rhuav tshem nws cov geometric raug. Kev nkag siab txog qhov tshwj xeeb ntawm cov khoom siv dig muag -txawm nws yog cov organic, ntxhia, lossis nws yog xim hlau- yog thawj kauj ruam ntawm kev xaiv qhov tseeb tu zaus thiab txoj hauv kev los kho qhov screen rau nws qhov qub "qhib cheeb tsam" specifications.

Lub Phenomenon ntawm Pegging hauv Vibratory Systems

"Pegging" yog ib qho kev nruj dua ntawm kev thaiv qhov uas nyob ze - cov khoom me me dhau los ua cov txheej txheem hauv cov mesh qhib. Qhov no yog tshwj xeeb tshaj yog nyob rau hauv mining thiab aggregate tshuaj ntsuam qhov twg cov hais yog ib tug nyuaj thiab irregularly zoo li. Tsis zoo li qhov muag dig muag, pegged hais tsis tuaj yeem txhuam tau yooj yim; lawv xav tau txhua yam zog los yog thermal expansion yuav tsum tau dislodged. Yog tias cov khoom no nyob twj ywm, lawv ua raws li "kev ntxhov siab risers," tsim kom muaj kev sib haum xeeb hauv cheeb tsam uas tuaj yeem ua rau cov hlau qaug zog thiab kev tawg thaum kawg. Pab pawg tu yuav tsum tau cob qhia kom paub qhov txawv ntawm ob qho xwm txheej no, vim tias kev siv tshuab nruj heev uas yuav tsum tau ua kom tshem tawm pegging tuaj yeem ua rau qee zaum ua kom zoo nkauj zoo nkauj -mesh cov ntxaij vab tshaus yog tias tsis siv nrog qhov tseeb.

Lub zog ntawm Ultrasonic Cleaning Technology

Ultrasonic tu yog dav suav hais tias yog "tus qauv kub" rau kev kho kom zoo -mesh stainless hlau cov ntxaij vab tshaus. Cov txheej txheem no siv siab - zaus suab nthwv dej los tsim ntau lab lub tshuab nqus tsev vacuum hauv cov tshuaj ntxuav tu-ib qho tshwm sim hu ua cavitation. Thaum cov npuas no tawg tawm tsam cov hlau nto, lawv tso tawm lub zog tawg ntawm lub zog uas "scrubs" tshem cov kab mob txawm tias los ntawm qhov tsawg tshaj plaws ntawm qhov 635-mesh screen. Txoj kev no yog qhov tshwj xeeb "zoo" vim nws tsis yog- abrasive; nws cleans lub sab hauv ntawm lub weave yam tsis xav tau hnyav txhuam uas yuav tshem tau cov xov hlau. Rau cov ntxaij lim dej tseem ceeb siv hauv aerospace lossis kev tsim khoom siv kho mob, kev tu ultrasonic feem ntau yog tib txoj kev pom zoo los xyuas kom meej qhov kev tshem tawm ntawm cov khoom seem.

Tshuaj Pickling thiab Degreasing raws tu qauv

Nyob rau hauv ib puag ncig uas mesh raug rau cov roj hnyav, roj, lossis cov nplais ntxhia, kev tu txhua yam ib leeg feem ntau tsis txaus. Kev siv tshuaj degreasing yog siv cov kuab tshuaj tshwj xeeb lossis cov tshuaj ntxuav alkaline uas rhuav tshem cov kab mob molecular ntawm cov kab mob organic. Tom qab degreasing, "pickling" tej zaum yuav tsum tau tshem tawm tob -seated metallic oxides los yog nplai. Qhov no suav nrog kev siv cov tshuaj acidic (feem ntau yog ib qho kev sib xyaw ntawm nitric thiab hydrofluoric acids) uas tshem tawm cov txheej microscopic ntawm hlau nto. Thaum lub suab nrov nrov, nws yog cov txheej txheem tswj xyuas uas ua kom lub hauv paus stainless hlau huv si zoo kawg nkaus thiab npaj rau qhov rov ua dua - tsim ntawm nws cov txheej txheem oxide tiv thaiv. Nws yog ib qho tseem ceeb uas yuav tsum tau siv cov tshuaj muaj tseeb kom tsis txhob "dhau -etching," uas tuaj yeem ua rau cov xov hlau nyias nyias thiab hloov qhov ntsuas micron ntawm lub lim.

Siab-Ntxhiab rov qab-Pulsing thiab Rov Qab-Xav

Rau cov ntxaij vab tshaus sib xyaw ua ke rau hauv cov tshuab ntws tsis tu ncua, xws li cov hauv cov roj refineries lossis cov chaw kho dej, kev tu "offline" tsis yog ib qho kev xaiv. Cov tshuab no cia siab rau rov qab-kev ntxuav, qhov twg cov kev taw qhia ntawm cov kua dej ntws rov qab ib ntus ntawm qhov siab dua. Qhov kev tawm dag zog ntawm lub zog no tau ntim cov khoom tawm ntawm lub mesh apertures los ntawm "sab huv" mus rau "sab qias neeg." Thaum ua tau zoo, rov qab-kev ntxhua khaub ncaws tuaj yeem tswj tau qhov kev tshuaj ntsuam kev ua tau zoo rau lub hlis yam tsis muaj kev cuam tshuam tag nrho. Txawm li cas los xij, pab pawg saib xyuas yuav tsum ua tib zoo saib xyuas "Delta P" (kev poob siab) kom ntseeg tau tias lub nraub qaum - ntxuav lub siab yog siab txaus kom tshem tawm cov khib nyiab tab sis qis txaus kom tsis txhob "shucking" lub mesh-ib qho kev puas tsuaj uas lub mesh tau ripped tawm ntawm nws cov qauv kev txhawb nqa los ntawm kev quab yuam ntau dhau.

Kev sib piv xaiv Matrix rau Mesh Cleaning Methods

Lub Logic ntawm Surface Chemistry Restoration

Stainless hlau tsis kam mus corrosion tsis tas li; nws nyob ntawm kev noj qab haus huv "passive txheej" ntawm chromium oxide. Thaum lub sijhawm ua haujlwm, cov khoom siv abrasive lossis cov tshuaj hnyav tuaj yeem ua rau cov txheej txheem no, ua rau cov hlau hauv qab tsis zoo rau xeb. Passivation yog tus txheej txheem ntawm immersing lub ntxuav mesh nyob rau hauv ib tug me ntsis oxidant, xws li nitric los yog citric acid. Cov tshuaj kho mob no ua haujlwm rau ob lub hom phiaj: nws dissolves ib qho "tramp hlau" (microscopic hais txog carbon steel los yog hlau) uas tej zaum yuav tau embedded nyob rau hauv lub nto, thiab nws yuam kev loj hlob sai ntawm ib tug tuab, uniform chromium - oxide zaj duab xis. Yog tias tsis muaj kev cuam tshuam tsis tu ncua, lub vijtsam 316L nyob rau hauv ib puag ncig saline yuav nws thiaj li tsim "tshuaj yej staining" lossis pitting, ua rau nws lub neej ua haujlwm luv.

Citric vs. Nitric Acid Passivation

Tau ntau xyoo, nitric acid yog tus qauv kev lag luam rau kev ua haujlwm, tab sis nws muaj kev phom sij rau kev ua haujlwm thiab kev puas tsuaj ib puag ncig. Cov txheej txheem txij nkawm niaj hnub no tau hloov mus rau citric acid-raws li tshuab. Citric acid yog "zoo" vim tias nws yog cov organic, biodegradable, thiab muaj kev nyab xeeb rau cov neeg ua haujlwm, tab sis nws muaj txiaj ntsig zoo ntawm "chelating" (binding) dawb hlau yam tsis muaj kev tawm tsam cov chromium lossis npib tsib xee hauv cov hlau. Hauv kev lag luam zaub mov thiab dej haus, citric acid passivation yog nyiam vim tias nws tsis muaj tshuaj lom. Txawm hais tias siv cov kua qaub, tus yuam sij rau lub neej ua haujlwm tau zoo yog ua kom lub ntsej muag kom huv si thiab qhuav tom qab cov txheej txheem, vim tias cov kua qaub seem nyob rau hauv lub weave tuaj yeem ua rau muaj kev cuam tshuam hauv zos ntau dua li tiv thaiv nws.

Kev soj ntsuam pom thiab "Linen Tester" Kev Ntsuam Xyuas

Daim ntawv tseem ceeb tshaj plaws tseem ceeb tshaj plaws ntawm kev saib xyuas yog qhov kev tshuaj xyuas tsis tu ncua ntawm cov mesh. Cov kws kho mob yuav tsum siv "Linen Tester"- lub iav tsom iav tshwj xeeb nrog kev tsim- hauv nplai- txhawm rau txheeb xyuas "xaim tsiv teb tsaws chaw" lossis "txoj kab streaks." Sij hawm dhau mus, qhov nro ntawm lub vijtsam tuaj yeem ua rau cov xaim hloov pauv, tsim kom loj dua - dua li - qhov tshwj xeeb uas tso cai rau cov khoom loj dhau mus. Los ntawm kev suav txhua lub lim tiam ntawm cov xov hlau nyob hauv ib qho -inch square, pab pawg saib xyuas tuaj yeem txheeb xyuas thaum twg lub vijtsam tau pib poob nws qhov kev ncaj ncees geometric. Qhov kev kuaj xyuas zoo no tuaj yeem tiv thaiv "tso tawm" thaum lub sijhawm tsim khoom, uas yuav ua rau muaj kev ua tiav ntawm cov khoom raug tsis lees paub vim muaj kev sib kis.

Ntsuas Hlau Txoj kab uas hla rau hnav txwv

Hauv cov ntawv thov abrasive, xws li sifting xuab zeb lossis hmoov hlau, cov xov hlau ntawm lub vijtsam ua haujlwm zoo li lub tread ntawm lub log tsheb - lawv maj mam hnav. Raws li txoj kab uas hla (d) txo qis, qhov aperture loj (w) nce, thiab tag nrho cov neeg kho tshuab lub zog ntawm cov mesh poob. Ib qho tseem ceeb ntawm kev tswj xyuas lub neej yog siv lub micrometer los ntsuas cov hlau tuab ntawm cov ntsiab lus ntawm kev sib txhuam siab tshaj plaws. Feem ntau cov qauv kev lag luam pom zoo tias lub vijtsam yuav tsum tau so haujlwm thaum cov xov hlau poob 15% mus rau 20% ntawm lawv cov tuab tuab. Dhau li ntawm qhov no, qhov kev pheej hmoo ntawm kev puas tsuaj "tawg" nyob rau hauv siab nce exponentially. Kev khaws cov ntaub ntawv keeb kwm ntawm cov kev ntsuas no tso cai rau cov kws ua choj los kwv yees qhov tseeb "Lub Sijhawm Nruab Nrab Nruab Nrab" (MTBF) thiab teem sijhawm hloov pauv thaum lub sijhawm teem sijhawm.

Lub sijhawm ntev - kev ua tau zoo ntawm lub vijtsam stainless hlau yog qhov cuam tshuam ncaj qha ntawm qhov zoo ntawm nws cov kev saib xyuas. Raws li peb tau tshawb nrhiav hauv phau ntawv qhia no, lub vijtsam "zoo" tuaj yeem yooj yim los ua lub luag haujlwm yog tias qhov muag tsis pom kev, yog tias kev ntxuav yog ua nrog cov tshuaj tsis raug cai, lossis yog tias cov qauv hnav ntawm cov xov hlau tsis raug saib xyuas. Kev hloov pauv los ntawm kev xav txog kev saib xyuas tsis zoo- qhov twg lub vijtsam tsuas yog hloov tom qab nws tawg - mus rau txoj hauv kev tswj hwm lub neej muaj txiaj ntsig kev lag luam loj. Nws ua kom ntseeg tau tias qhov "qhib cheeb tsam" tseem nyob ib puag ncig, uas ua rau kom ruaj khov ntawm kev siv lub zog ntawm cov twj thiab cov kiv cua uas yuav tsum thawb cov kua dej los ntawm cov mesh.

Thaum kawg, kev saib xyuas yog ib qho ntawm kev khaws cia "engineered precision" ntawm lub mesh. Txawm hais tias los ntawm microscopic tu lub zog ntawm ultrasonics, cov tshuaj rov qab los ntawm passivation, los yog kev kuaj xyuas nruj ntawm micrometer ntsuas, txhua kauj ruam hauv kev tu lub voj voog ua haujlwm los tiv thaiv kev ncaj ncees ntawm cov txheej txheem. Los ntawm kev kho cov tshuaj ntsuam stainless hlau ua ib qho khoom muaj txiaj ntsig zoo dua li cov khoom siv pov tseg, cov tswv lag luam tuaj yeem ua kom muaj kev nyab xeeb ntawm lawv cov khoom, lub neej ntev ntawm lawv cov cuab yeej, thiab tag nrho cov txiaj ntsig ntawm lawv cov khoom lag luam thoob ntiaj teb. Qhov zoo-cov tshuaj ntsuam xyuas yog lub cim ntawm lub ntiaj teb-chav tsev tsim khoom.
