Ua ntej cov khoom hlau yog adhesively bonded rau hauv cov qauv dav hlau, lawv tau dhau los ua qhov kev npaj ua kom nruj- feem ntau cuam tshuam nrog deoxidizing hauv cov kua qaub, tom qab ntawd yaug dej kub. Txhua yam kab mob hlau nyob hauv cov dej yaug tuaj yeem ua rau cov nplaum nplaum ntawm cov kab ntawv sib txuas, ua rau tsis muaj zog lossis ua tsis tiav. HauvPTFE rhaub deoxidizing yaug aerospacecov txheej txheem, thermal tswj yog ncaj qha mus rau daim ntawv cog lus durability thiab cov qauv kev ntseeg tau.
Lub luag hauj lwm ntawm Post-Deoxidizing yaug hauv Adhesive Bond Preparation
Tom qab kev kho mob hauv chav da dej deoxidizing-feem ntau muaj nitric-hydrofluoric acid sib tov- cov khoom siv hlau khaws cov khoom seem ntawm cov khoom siv tshuaj tiv thaiv thiab cov khoom paug. Cov residues yuav tsum tau muab tshem tawm ua ntej cov nplaum nplaum los xyuas kom meej qhov kev ua kom zoo.
Rinsing yog ua tam sim ntawd tom qab deoxidizing, feem ntau yog siv deionized (DI) dej los tiv thaiv ionic paug. Txhawm rau txhim kho tus cwj pwm kom qhuav thiab txo qhov pom dej, cov tso tsheb hlau luam yaug feem ntau ua haujlwm ntawm qhov kub siab ntawm 60℃thiab 80 degree.
Ntawm qhov kub thiab txias no, kev tshem tawm dej yog nrawm dua, thiab kev huv ntawm qhov chaw tau zoo dua ua ntej kev sib txuas ua haujlwm.
Qhov tseem ceeb ntawm cov khoom siv cua sov hauv Cov Dej purity
Kev zam Ionic Contamination ntawm Bond Interface
Hauv kev ua haujlwm ntawm kev sib txuas ua ke, cov dej zoo yog txuas ncaj qha rau daim ntawv cog lus ruaj khov. Txhua yam yaj ntawm cov hlau ions tau qhia thaum lub sij hawm yaug tuaj yeem nyob ntawm qhov chaw substrate thiab cuam tshuam nrog cov nplaum curing chemistry.
Cov cua sov hlau ua rau muaj kev pheej hmoo nyob rau theem no. Corrosion lossis degradation tuaj yeem tso cov hlau, tooj liab, lossis lwm yam ions rau hauv dej yaug. Cov kab mob no tuaj yeem tso rau hauv cov hlau uas huv huv, tsim cov ntsiab lus tsis muaj zog hauv zos lossis corrosion- cuam tshuam cuam tshuam thaum siv cov nplaum.
Cov kev sib kis no tuaj yeem txo cov kev sib raug zoo thiab kev cuam tshuam kev ua raws li cov qauv hauv aerospace, suav nrog ASTM thiab OEM kev sib txuas lus tshwj xeeb.
A PTFE rhaub deoxidizing yaug aerospaceconfiguration tshem tawm qhov kev pheej hmoo no los ntawm kev muab tag nrho inert wetted nto. PTFE tsis tso cov hlau ions thiab tseem muaj tshuaj lom neeg ruaj khov txawm tias muaj cov kua qaub residual los ntawm theem deoxidizing.
Thermal Performance nyob rau hauv DI Dej Rinse Systems
Cov cua sov ruaj khov ntawm 60-80℃Kev Ua Haujlwm Ntau Yam
Cov tso tsheb hlau luam yaug feem ntau yog khaws cia ntawm 60℃thiab 80 degree, ntau yam xaiv los sib npaug kom ziab kom zoo, kev huv huv, thiab kev nyab xeeb ntawm cov txheej txheem. PTFE immersion heaters yog zoo haum rau daim ntawv thov no vim lawv muaj peev xwm ua hauj lwm yam xyuam xim txog li ntawm 110 degree, muab txaus thermal margin rau ruaj khov.
Temperature uniformity yog qhov tseem ceeb. Cov cua kub tsis sib xws tuaj yeem ua rau muaj kev kub ntxhov hauv zos lossis stratification, uas tuaj yeem cuam tshuam rau kev ua haujlwm zoo thiab qhov sib xws. Lub tank agitation los yog ncig yog feem ntau ua hauj lwm los xyuas kom meej homogeneous kub faib.
Lub tshuab rhaub cua sov yog tsim los tswj kom ruaj khov thermal tej yam kev mob es tsis txhob kub kub flux, kom ntseeg tau tias rov ua kom rov ua tau zoo nyob rau hauv ntau lawm.
Kev txiav txim siab zoo hauv kev npaj daim ntawv cog lus
Conductivity Control thiab Water Purity Verification
Ib qho tseem ceeb ntawm kev ruaj ntseg zoo hauv kev ua haujlwm ntawm lub tank yog kev soj ntsuam tas li ntawm dej conductivity. Kev ntsuas kev coj ua tau muab qhov qhia ncaj qha ntawm ionic contamination theem hauv DI dej systems.
Ua ntej cov nplaum nplaum, cov dej ntws yaug tau raug txheeb xyuas kom ntseeg tau tias ua raws li kev ua kom huv huv uas tau teev tseg los ntawm cov qauv tsim hauv aerospace. Cov qib siab conductivity yuav qhia tau tias muaj kab mob los ntawm cov txheej txheem nqa khoom, cov khoom siv tank, lossis cov khoom siv cua sov.
Kev tuav cov conductivity tsawg yog qhov tseem ceeb los xyuas kom meej tias tsis muaj cov khoom seem nyob hauv qhov chaw uas tuaj yeem cuam tshuam cov nplaum ntub dej lossis kev coj tus cwj pwm.
Kev koom ua ke rau hauv Aerospace Bonding txheej txheem
Ua kom muaj kev ncaj ncees ntawm qhov chaw ua ntej daim ntawv thov nplaum
Nyob rau hauv aerospace structural bonding ua hauj lwm, lub sij hawm yaug ua hauj lwm raws li ib tug zaum kawg tshuaj txias kauj ruam ua ntej daim ntawv nplaum. Ib qho kev sib kis tau qhia nyob rau theem no yuav raug kaw mus tas li ntawm daim ntawv cog lus interface.
PTFE immersion heaters muab qhov chaw ruaj khov thiab inert cua sov uas khaws cov dej purity thoob plaws hauv kev ua haujlwm. Qhov no ua kom pom tseeb tias qhov chaw tseem muaj tshuaj huv si thiab npaj rau kev sib txuas ua ke.
Los ntawm kev tshem tawm cov kev pheej hmoo ntawm cov hlau tsis huv, PTFE cov cua sov ua haujlwm ncaj qha rau cov ntawv cog lus rov ua tau zoo thiab ntev - lub sijhawm ua haujlwm ntawm cov qauv.
Xaus: Cov Cuab Yeej Huv Huv rau Kev Pom Kev Tsis Pom Zoo -Line Integrity
PTFE immersion heaters sawv cev rau ib qho me me tab sis tseem ceeb hauv cov khoom siv nplaum nplaum. Los ntawm kev xa cov cua sov kom huv, tswj cov cua sov hauv deoxidizing lub tank, qhov kev pheej hmoo ntawm kev sib kis tau raug txo kom tsawg thiab kev ua kom zoo ntawm qhov chaw yog khaws cia.
Hauv kev tsim khoom hauv aerospace, kev ntseeg siab ntawm cov nplaum nplaum tsis yog nyob ntawm qhov nplaum nws tus kheej nkaus xwb tab sis ntawm kev huv ntawm txhua kauj ruam ua ntej. Qhov kev ncaj ncees ntawm cov qauv kev sib raug zoo yog qhov kawg txhais los ntawm qhov purity ntawm qhov chaw nyob rau lub caij sib koom, qhov twg txawm tias cov kab mob sib kis tuaj yeem txiav txim siab ntev - lub sijhawm ua haujlwm.
