Vim li cas Vuam Fume yog daim ntawv thov tawv
Feem ntau welding fumes yog dominated los ntawmultrafine hais(feem ntau hauv qab 1 μm, nrog cov ntsiab lus feemqis dua 0.5 m), ntxiv rau condensed hlau oxides uas tuaj yeem coj tacky ntawm lub lim dej. Qhov kev sib xyaw ua ke no ua rau peb qhov mob tshwm sim:
Kev poob siab nrawm nce siab (thaum pib zoo li "zoo," ces nce nrawm)
Cov plua plav tsis zoo tso tawm hauv qab mem tes (khoom qab zib yuav tsis tawg kom huv)
Thaum ntxov qhov muag tsis pom kev (tshwj xeeb tshaj yog cov av noo, roj pos huab, los yog flux residue)
Hauv cov ntsiab lus siv plua plav collector, koj xav tau cov xov xwm uas:
1.captures nplua particles tsis sib sib zog nqus loading, thiab
2. tso lub ncuav mog qab zib kom ntseeg tau thaum ntaus nrog mem tes.
Qhov ntawd yog qhov filtration.
Nto filtration hauv Plain Terms
Qhov "surface filtration" txhais tau li cas
Qhov tseeb qhov chaw-filtration media ua lub ncuav mog qab zib hmoov avnyob saumntawm media, tsis tob hauv nws. Qhov ntawd ua rau lub qhov hws qhib thiab ua rau pulse - ntxuav kom zoo.
Thaum pom hloov mus rau qhov tob -loading:
• cov khoom embed hauv fiber ntau matrix,
• Cov xov xwm yuav nyuaj dua los ntxuav,
• Kev poob siab nce siab thiab tsis zoo siab tom qab pulsing.
Peb cov engineers feem ntau pomcov chaw ua phem rau cov mem tes li qub lossis cov cua compressed, thaum qhov teeb meem tiag tiag yog cov xov xwm xaiv tau txhawb qhov tob -loading hauv submicron daim ntawv thov.
Khoom Description
H3 Microscopic qauv
Nanofiber media feem ntau yog ananofiber txheej tso rau hauv cellulose/polyester substrate. Txoj kab uas hla ntawm fiber ntau yog qhov me me piv rau cov pa spunbond fibers, uas ua rau thaj tsam ntawm qhov chaw thiab txo qhov pore loj ntawm cov txheej saum toj kawg nkaus.
H3 Yuav ua li cas nws lim vuam fume
• Cov txheej nanofiber txhim khopib efficiencyrau nplua particle.
•Nws thawb pom mus raunto ncuav mog qab zib tsim, tshwj xeeb tshaj yog piv nrog dawb spunbond polyester.
• Hauv vuam fumes, qhov no feem ntau txhais tau tiaszoo dua thaum ntxov -stage capturethiab ib tug qeeb drift rau hauv embedded loading.
H3 Lub zog hauv cov nroj tsuag tiag
Nanofiber feem ntau muaj zog haum thaum:
• fume loading yog nruab nrab,
• cov plua plav yog "qhuav" thiab tsis oily,
• koj xav tau ibsib npaug ntawm cov nqi thiab kev ua haujlwm.
Nws tuaj yeem xa cov kev ua tau zoo yam tsis muaj tus nqi them nqi ntawm daim nyias nyias - yog tias daim ntawv thov kev tswj xyuas nyob twj ywm.
PTFE Membrane Media: Microstructure thiab Nws Ua Haujlwm li cas
H3 Microscopic qauv
PTFE membrane media siv amicroporous PTFE zaj duab xis laminated rau hauv substrate(feem ntau polyester). Xav tias nws yog ib txheej txheej txheej uas muaj kev tswj hwm micro- pores.
H3 Yuav ua li cas nws lim vuam fume
Lub membrane coj zoo li ibzoo ib yam nto barrier, txo qhov tob -loading.
Cov khoom zoo raug ntes ntawm / ze ntawm qhov chaw thiab tsim lub ncuav mog qab zib uas tuaj yeem tso tawm thaum lub sijhawm ua pa.
Vim hais tias daim nyias nyias yog nyias txheej, nws nyhavruaj khov nyob thoob plaws ntau hom hmoov av.
H3 Lub zog hauv cov nroj tsuag tiag
PTFE membrane feem ntau yog qhov kev xaiv zoo dua thaum:
cov fume zoo heev (xws li hnyav sub-0.5 μm feem),
koj pom cov av noo swings lossis qee zaus roj pos huab,
koj xav tau cov mem tes uas kwv yees tshaj plaws - ntxuav rov qab.
Khoom Description
Pulse tu yog ib qho kev tshwm sim txhua yam: qhov tawg luv luv ntawm huab cua tsim ib qho kev poob siab thiab flex hauv xov xwm, tawg lub ncuav mog qab zib dawb.
Nrogultrafine hmoov av, lub ncuav mog qab zib tuaj yeem coj tus cwj pwm zoo li cov pa luam yeeb nyob hauv - nyias, sib sib zog nqus, thiab qee zaum nplaum. Media xaiv txiav txim seb lub ncuav mog qab zib puas huv si los yog smears rau hauv cov qauv.
H3 Nanofiber hauv qab mem tes
Hauv ntau qhov vuam fume systems:
•Nanofiber tuaj yeem ntxuav tau zoo thaum ntxov hauv lub neej cartridge.
• Kev ua tau zoo nyob ntawm qhov hnyavhuab cua-rau- ntaub piv, mem tes siab, thiab plua plav tej yam kev mob.
•Yog hais tias ib puag ncig qhia cov roj, noo noo, los yog tacky condensables, nanofiber yuav maj mam hloov mus rau embedded loading.
Tswv yim kos npe:DP nce tsis tu ncua thiab lub suab tsis rov qab pib dua li tom qab ob peb lub lis piam / hli.
H3 PTFE membrane hauv qab mem tes
• PTFE membrane nyhav rau:
• Khaws cov plua plav ntawm qhov chaw ntev dua,
• khaws cov mem tes kom zoo dua qub,
• tiv thaiv "smearing" piv rau fiber ntau-tsuas yog cov qauv.
Tswv yim kos npe:DP qauv yog qhov ruaj khov dua thiab rov zoo dua tom qab hloov pauv ntawm lub neej ntawm daim cartridge.
H3 Txoj cai yooj yim ntawm tus ntiv tes xoo
•Yog tias koj xav tau qhov kev nyab xeeb tshaj plaws nrog cov pa taws sub-0.5 μm,PTFE membrane feem ntau yog qhov kev zam txim ntau dua.
•Yog tias koj cov txheej txheem ruaj khov thiab qhuav thiab koj xav tau tus nqi - txhim kho zoo los ntawm cov qauv polyester,nanofiber feem ntau txaus.
Dab tsi Cov Chaw Engineers Yuav Tsum Sib Piv (Tshaj Tawm Daim Ntawv Muag Khoom)
Thaum cov neeg yuav khoom sib piv cov xov xwm, lawv feem ntau tsom rau kev thov kev ua haujlwm. Rau vuam fume, qhov sib piv muaj txiaj ntsig zoo dua yog DP tus cwj pwm nyob rau lub sijhawm.
Nug cov ntsiab lus no:
• Thaum xub thawj tsis kam (siab poob) ntawm ib tug txhais tau tias airflow
• DP kev cia siab(Nws nce sai npaum li cas hauv cov ntawv thov zoo sib xws)
•Pulse- ntxuav rov qab(DP puas poob rov qab tom qab lub voj voog mem tes)
•Lub zog substrate thiab kev sib txuas zoo (tseem ceeb rau kev qaug zog ntawm lub plawv)
Yog tias tus neeg muag khoom tsis tuaj yeem tham txog cov ntsiab lus no, koj yuav twv yuav raug hu.
Daim ntawv pom zoo: Vuam vs Laser Txiav
H2 Vuam (MIG/TIG/Arc) - Qhov peb feem ntau pom zoo
Vuam fumes feem ntau siab nyob rau hauv ultrafine hlau oxide hais.
Pom zoo: PTFE membranethaum:
• koj muaj lub luag haujlwm siab,
• koj pom DP nquag nquag,
•koj khiav cua siab dua- rau- cov ntaub ntawv piv,
•los yog koj cov plua plav yuav ua rau dig muag.
Pom zoo: nanofiberthaum:
•koj xav tau kev txawj ntse los ntawm tus qauv polyester,
• ib puag ncig yog qhuav,
•koj tau tswj huab cua- mus rau- ntaub thiab lub plawv dhia ruaj khov.
Cov ntsiab lus tseem ceeb:Yog tias koj tab tom nrhiav kev hloov pauv ntev dua thiab ruaj khov DP, cov xov xwm membrane feem ntau yeej.
H2 Laser Txiav - Dab tsi hloov
Laser txiav tuaj yeem ua kom paub cov khoom zoo heev ntxiv rau cov txheej txheem- tshwj xeeb condensables nyob ntawm cov khoom siv thiab cov pa roj.
Pom zoo: PTFE membranethaum:
• cov plua plav coj cov nplaum,
• muaj cov seem uas pom,
• lossis koj pom cov xwm txheej dig muag sai.
Nanofiber tuaj yeem ua haujlwmthaum:
• cov hmoov av qhuav thiab nkig,
• loading yog nruab nrab,
• koj ua qhov tseem ceeb ntawm tus nqi qis dua.
Peb cov engineers feem ntau pomlaser txiav kab txhim kho tau zoo heev los ntawm kev txav los ntawm cov polyester dawb mus rau ib qho chaw- pom cov xov xwm. Qhov thib ob dhia (nanofiber → membrane) feem ntau yog kev ncaj ncees thaum cov plua plav lossis ib puag ncig tsis tshua pom tau.
Yuav Ua Li Cas Xaiv Ntawm Nanofiber thiab PTFE hauv Ib nplooj ntawv
H3 Xaiv nanofiber yog tias koj xav tau:
• tus nqi -zoo nto- pom kev hloov pauv
•good ntxov-kev ua tau zoo rau lub neej rau cov khoom zoo
• txhim kho ncuav mog qab zib tsim vs txheem polyester
• Kev ua tau zoo ntawm cov khoom qhuav, ruaj khov
H3 Xaiv PTFE membrane yog tias koj xav tau:
• qhov ua tau zoo tshaj plaws nrog sub-0.5 μm fume
• zoo dua tiv thaiv qhov muag tsis pom kev nyob rau hauv qhov sib txawv ntawm cov av noo / roj pos huab
• muaj zog pulse- ntxuav kev ruaj khov nyob rau lub sijhawm ua haujlwm ntev
• Kev pheej hmoo tsawg dua thaum kev ua haujlwm hloov pauv
Cov kab hauv qab:Rau vuam fume extraction lim qhov twg downtime yog kim,PTFE membrane feem ntau yog qhov kev nyab xeeb dua. Nanofiber feem ntau yog tus nqi zoo tshaj plaws thaum muaj kev tswj hwm thiab lub hom phiaj yog kev hloov kho tam sim ntawd los ntawm cov txheej txheem xov xwm.
Spec Notes Cov neeg yuav khoom yuav tsum muab tso rau hauv RFQ
Peb tsim cov khoom siv lim hauv -lub tsev thiab txhawb OEM / ODM cov haujlwm rau kev sau cov plua plav thiab cov cua tshuab. Qhov ntawd txhais tau tias:
Hoobkas- tus nqi ncaj qha(tsis muaj tus neeg nruab nrab markup),
zoo ib yam tswj nyob rau hauvISO 9001 Daim ntawv pov thawj,
kev cai qhov ntev, lub kaus mom kawg, gaskets, thiab ntim rau koj tus neeg sau khoom,
ceev sampling rau validation ua ntej bulk xaj.
Yog tias koj qhia koj tus qauv sau, qhov ntev ntawm daim cartridge, thiab koj qhov kev poob siab tam sim no, peb yuav pom zoo rau cov xov xwm zoo (nanofiber vs PTFE) thiab hais ib qho zoo li - rau -zoo li hloov.
