Kub alkaline degreasing tso tsheb hlau luam tso rau tib lub sijhawm xav tau ntawm cov tshuaj tiv thaiv, kev hloov hluav taws xob, kev siv lub zog, thiab hluav taws xob rwb thaiv tsev. Acua sov phajuas yog nyias nyias yuav muaj kev ruaj ntseg txhua yam, thaum lub thickness ntau dhau tuaj yeem ua rau cov thermal kuj thiab qeeb hloov hluav taws xob.
Txoj haujlwm ua haujlwm engineering yog nrhiav qhov tuab uas txhawb nqa cov qauv uas yuav tsum tau ua yam tsis tsim cov thermal loading tsis tsim nyog.
Thickness Hloov Thermal Path
Thaum tshav kub kub generated nyob rau hauv lub cua sov phaj yuav tsum mus los ntawm cov khoom ua ntej nkag mus rau hauv lub alkaline tov.
Ib qho yooj yim thermal-kev sib raug zoo yog:
Rth=L / (kA)
qhov twg L yog cov khoom tuab, k yog thermal conductivity, thiab A yog qhov chaw ua haujlwm.
Raws li thickness nce, thermal kuj tseem nce thaum lwm yam hloov pauv tsis hloov.
Rau PTFE cua sov daim hlau, cov nyhuv no tsim nyog mloog vim PTFE muaj thermal conductivity tsawg piv nrog ntau cov hlau.
Nyias Kev Tsim Kho Txhim Kho Thermal Teb
Txo cov khoom thickness ua kom lub tshav kub- hloov txoj kev.
Qhov no tuaj yeem pab cov cua sov saum npoo teb sai dua tom qab siv fais fab.
Fast thermal teb yuav pab tau nyob rau hauv degreasing tso tsheb hlau luam uas muaj ib tug ntau zaus ntawm kub hloov los ntawm txias workpieces los yog chemical replenishment.
Txawm li cas los xij, thermal teb tsuas yog ib qho yuav tsum tau ua.
Lub phaj cua sov yuav tsum nyob twj ywm mechanically ruaj khov thaum lub sij hawm installation thiab rov qab thermal cycling.
Thickness ntau dua tuaj yeem txhim kho kev ruaj ntseg
Cov txheej txheem cua sov thicker yuav muab ntau dua rigidity thiab tsis kam mus deformation.
Qhov no tuaj yeem ua rau muaj txiaj ntsig zoo rau cov phiaj xwm cua sov loj uas tau teeb tsa vertically lossis kab rov tav hauv cov tso tsheb hlau luam.
Mechanical loading tej zaum yuav yog los ntawm cov kua txav, kev teeb tsa, kev vibration, tuav, thiab thermal expansion.
Qhov tseeb thickness yog li ntawd nyob ntawm ib feem ntawm lub cev loj thiab mounting txoj kev.
| Thickness Txoj Kev | Thermal Resistance | Mechanical Stability | Hom Kev Lag Luam -Tawm |
|---|---|---|---|
| Nyias | qis | qis | Teb ceev ceev |
| Nruab nrab | Sib npaug | Sib npaug | Kev siv dav dav |
| tuab | Siab dua | Siab dua | Tsawg thermal teb |
| Ntev dhau lawm | Siab | Muaj peev xwm tsis tsim nyog | Txo thermal efficiency |
Kev sib piv muab cov kev taw qhia dav dav dav dav es tsis yog universal thickness specification.
PTFE Chemical Resistance Tsis Tshem Tawm Thermal Limits
PTFE feem ntau yog siv rau alkaline cua sov daim ntaub ntawv vim hais tias ntawm nws muaj zog tshuaj tiv thaiv thiab hluav taws xob rwb thaiv tsev yam ntxwv.
Txawm li cas los xij, kev sib raug zoo tshuaj lom neeg thiab kev ua haujlwm thermal yog cov lus nug tsim tshwj xeeb.
Qib PTFE tuaj yeem tiv taus cov tshuaj alkaline zoo thaum tseem yuav tsum tau ua tib zoo tsim thermal ntawm qhov kub siab.
Kev khiav hauj lwm kub, lub sij hawm raug, concentration, thiab mechanical loading yuav tsum xav txog tag nrho.
Lub zog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom
Piv txwv li lub phaj cua sov xa 4 kW los ntawm thaj tsam ntawm 0.12 m².
Qhov nruab nrab kub flux yog kwv yees li:
4,000 ÷ 0.12=33.3 kW/m²
Yog tias cov khoom siv ntau dua ua rau cov thermal tsis kam, cov khoom siv cua sov sab hauv yuav tsum tau ua haujlwm ntawm qhov kub siab dua kom tswj tau qhov kub hloov mus rau hauv chav da dej.
Qhov no yog vim li cas thickness yuav tsum tsis txhob xaiv ntawm nws tus kheej los ntawm lub hwj chim ceev.
Ib qho hluav taws xob qis dua tuaj yeem muab cov txheej txheem thermal ntxiv thaum xav tau cov qauv tuab dua.
Degreasing da dej feem ntau muaj qhov xav tau thermal siab
Kub alkaline degreasing feem ntau ua haujlwm ntawm qhov kub siab thiab tuaj yeem ua cov khoom hlau tsis tu ncua.
Txias workpieces nkag mus rau hauv lub tank nqus cua sov:
Q=mCpΔT
Kev tsim khoom loj dua yog li ua kom rov qab xav tau.
Lub phaj cua sov uas muaj cov cua kub ntau dhau tuaj yeem siv sijhawm ntev dua los teb, thaum lub zog tsis txaus tuaj yeem ncua sijhawm rov qab.
Qhov zoo tshaj plaws configuration sib npaug cov khoom thickness, active cheeb tsam, thiab hluav taws xob tso zis.
Circulation pab tshem tawm cua sov los ntawm qhov chaw
Kev quab yuam kev tuaj yeem txhim kho cov cua sov hloov mus ib puag ncig ntawm lub phaj cua sov.
Thaum cov tshuaj alkaline ntws hla lub active nto, lub sov ciam txheej yog tsis tu ncua hloov.
Qhov no tuaj yeem txo qhov kub ntawm qhov sib txawv ntawm cov phaj thiab cov kua ntau.
Tsis muaj zog ncig muaj qhov cuam tshuam.
Rau cov txheej txheem PTFE tuab, kev ua haujlwm zoo ua qhov tseem ceeb tshwj xeeb vim tias txoj hauv kev thermal los ntawm cov khoom siv kuj tseem tiv taus.
Kev them nyiaj yug Mechanical tuaj yeem txo qhov xav tau ntawm cov tuab ntxiv
Kev nce thickness tsis yog tib txoj hauv kev los txhim kho cov qauv kev ruaj ntseg.
Ntxiv cov ntsiab lus mounting, qhov tsim nyog brackets, tswj kev txhawb nqa, lossis kev hloov pauv geometry tuaj yeem ua rau muaj qhov tsim nyog rau kev ua haujlwm nruj.
Txoj hauv kev no tuaj yeem tso cai rau cov qauv thermal ua haujlwm tau zoo.
Lub mounting system yuav tsum ua kom haum thermal expansion.
Thermal Cycling yuav tsum suav nrog
Degreasing tso tsheb hlau luam tuaj yeem rov ua dua ntawm qhov pib qhov kub thiab txias ua haujlwm.
Kev nthuav dav dua thiab kev cog lus tuaj yeem tsim kev ntxhov siab rau txhua yam.
Cov qauv tuab tuaj yeem zam qee qhov kev siv tshuab zoo dua, tab sis qhov sib txawv ntawm thermal expansion ntawm PTFE, conductors, terminals, thiab mounting hardware tseem xav tau kev saib xyuas.
Rigidly kho cov Cheebtsam nrog txawv expansion tus nqi tuaj yeem tsim kev ntxhov siab tsis hais qhov tuab.
Qhov Deposits tuaj yeem ua kom muaj txiaj ntsig zoo thermal
Alkaline degreasing cov kev daws teeb meem tuaj yeem tsim cov khoom seem lossis khaws cov kab mob sib kis nyob ntawm cov txheej txheem tsim khoom.
Ib txheej tso nyiaj ntxiv lwm qhov thaiv thermal.
Yog tias lub phaj cua sov twb tau tsim los nrog cov khoom siv loj, cov khoom tso tawm ntxiv tuaj yeem ua rau kom qhov kub thiab txias sib txawv ntawm cov khoom siv sab hauv thiab da dej.
Kev tshuaj xyuas niaj hnub yog li tseem ceeb txawm tias cov khoom siv phaj yog tshuaj tiv thaiv.
Tsis txhob xaiv Thickness ntawm Mechanical Strength ib leeg
Lub phaj cua sov tuab heev tuaj yeem tshwm sim los ntawm kev ua haujlwm zoo, tab sis tuaj yeem qhia qhov tsis tsim nyog thermal kuj.
Hloov pauv, xaiv cov qauv thinnest tuaj yeem tsim teeb meem kev teeb tsa lossis kav ntev.
The practical solution is a balanced thickness based on active area, power density, operating temperature, mounting conditions, chemical exposure, and expected thermal cycling.
Tswv yim Thickness xaiv
Rau cov kub alkaline degreasing tso tsheb hlau luam, cov khoom siv tuab tuab feem ntau yog qhov zoo dua thaum nws muab cov qauv kev ruaj ntseg txaus yam tsis tas yuav ua rau cov thermal tsis kam.
Qhov kawg tsim yuav tsum xav txog PTFE zog, xav tau wattage, active cheeb tsam, kev khiav hauj lwm kub, kua ncig, tank qhov ntev, mounting txoj kev, thiab thermal- voj voog zaus.
Rau cov cua kub kev cai, cov kev txwv no muab lub hauv paus txhim khu kev qha rau kev xaiv tuab dua li siv cov qauv tuab rau txhua lub tank. Cov qauv sib npaug tuaj yeem tswj xyuas cov tshuaj tiv thaiv thiab kev ruaj ntseg thaum khaws cia cov cua sov hloov mus rau hauv da dej alkaline.
