Unveiling the Core Technology of Oil Micro-Dej Detection: Professional Compatibility Ntawm GoldhomeHM401 thiab Karl Fischer Titration
Hauv kev ua haujlwm siab -cov khoom siv hluav taws xob hluav taws xob ua haujlwm thiab kev saib xyuas, cov dej noo hauv cov roj insulating ua haujlwm raws li "tsis pom txoj sia" txiav txim siab cov khoom siv kev nyab xeeb. Cov dej noo txo qis txo qhov tawg ntawm cov roj insulating, ua rau ib feem ntawm cov pa tawm, cov khoom siv aging, los yog luv luv - teeb meem hauv Circuit Court. Yog li ntawd, kev paub meej meej ntawm cov kab ya raws hauv cov roj yog qhov tseem ceeb heev. Goldhome tus kheej tsim HM401 Oil Trace Water Analyzer leverages qhov zoo ntawm Karl Fischer titration, tsim nws tus kheej raws li cov khoom nyiam rau kev ntsuas roj zoo hauv lub zog, roj av, thiab lwm yam lag luam. Kab lus no delves rau hauv cov ntsiab cai thiab cov khoom nta thaum qhia cov neeg siv khoom kom paub meej lawv cov kev xav tau kom tsis txhob yuam kev cov khoom nug.
I. Karl Fischer Titration: Qhov "Precision Standard" rau Trace Water Detection
Txoj kev Karl Fischer titration yog ib txoj kev tshawb nrhiav dej noo raws li cov tshuaj tiv thaiv electrolytic thiab Faraday txoj cai. Nws cov txiaj ntsig tseem ceeb suav nrog tshem tawm qhov xav tau rau kev npaj cov txheej txheem kev daws teeb meem thiab ua tiav microgram- qib kev txheeb xyuas qhov tseeb, ua rau nws tsim tshwj xeeb rau kev ntsuas qhov tseeb ntawm qis- cov qauv noo noo xws li cov roj insulating. Piv nrog rau cov txheej txheem volumetric ib txwm, nws muaj kev txhim kho tseem ceeb hauv kev tshawb pom kev ua haujlwm, cuam tshuam tsis kam, thiab automation. Nws cov ntsiab cai tshwj xeeb thiab cov yam ntxwv yog raws li hauv qab no:
1. Txoj Cai Ua Haujlwm tseem ceeb
Txoj kev no siv tas li -tam sim no electrolysis los tsim cov titrant (iodine), uas dhau los ua cov tshuaj lom neeg muaj pes tsawg leeg nrog cov dej noo hauv cov qauv: hauv reagent systems xws li methanol lossis imidazole, iodine reacts nrog dej hauv 1: 1 molar ratio los tsim hydroiodic acid. Cov cuab yeej ntsuas tau ntsuas cov dej noo los ntawm kev ntsuas cov nqi hluav taws xob siv thaum lub sij hawm electrolysis (raws li Faraday Txoj Cai:W = Q × M / (n × F),qhov twg Q yog them, M yog molar loj ntawm dej, thiab F yog Faraday qhov tas li). Thaum tag nrho cov dej noo hauv cov qauv raug noj, cov iodine ntau dhau ua rau muaj kev hloov pauv sai sai ntawm cov teeb liab electrode, ua rau lub ntsuas hluav taws xob nres thiab tso tawm qhov tshwm sim -tag nrho yam tsis muaj kev cuam tshuam los ntawm phau ntawv.
2. Technical Advantages thiab Application Scenarios
Lub zog tseem ceeb ntawm Karl Fischer titration method manifest nyob rau hauv peb yam:
Ua ntej, tshwj xeeb precision nrog kev tshawb nrhiav ntau yam 1ug txog 200mg. Rau cov qauv hauv 10ug txog 1000ug ntau yam, kev ntsuas qhov yuam kev yog tswj tsis pub dhau ± 3ug, ua kom pom cov kab ntub dej sib txawv hauv cov roj insulating.
Qhov thib ob, kev sim nrawm nrog ib qho kev tshuaj ntsuam feem ntau ua tiav hauv qab 60 vib nas this, ua tau raws li siab - zaus batch xeem xav tau.
Thib peb, tsawg kawg reagent noj raws li cov titrant tau txais los ntawm electrolysis, tshem tawm cov kev hloov nquag thiab muab sijhawm ntev - cov nqi zoo.
Txoj kev no yog qhov tshwj xeeb tshaj yog siv rau kev kuaj xyuas cov dej noo nyob rau hauv siab - cov khoom siv hluav taws xob hluav taws xob insulating roj (xws li roj transformer, cov roj hluav taws xob hluav taws xob), thaum tseem npog qis - cov qauv ntsuas dej noo hauv cov roj av thiab tshuaj lom neeg kev lag luam. Nws ua raws li cov qauv hauv tebchaws xws li GB / T 11133 rau coulometric titration siv Karl Fischer txoj kev.
II. HMDQ HM401: Cov Khoom Siv Ua Haujlwm Zoo rau Karl Fischer Coulometric Titration
Lub Goldhome HM401 Oil Trace Water Tester yog cov cuab yeej tshawb nrhiav kev cai -tsim rau lub siab -voltage hluav taws xob kev lag luam. Nws sib zog ua ke cov thev naus laus zis tseem ceeb ntawm Karl Fischer coulometric titration, ua tiav qhov kev hloov pauv hauv ob qho tib si kho vajtse thiab software ua haujlwm. Cov yam ntxwv tshwj xeeb muaj xws li:
1. Core Performance Parameters
Cov cuab yeej siv 0-400mA tsis siv neeg electrolytic tam sim no tswj ua ke nrog siab -precision electrode teeb liab kuaj xyuas circuitry kom ceev ceev titration endpoints, kom ntseeg tau tias ruaj khov thiab txhim khu kev qha. Nruab nrog 7-nti xim touchscreen txhawb ob hom lus Suav / lus Askiv hloov pauv, nws ua tau raws li kev thov thoob ntiaj teb. Cov kev ntsuas tuaj yeem teeb tsa thiab nkhaus spectra pom nrog lub teeb kov, ua kom muaj kev txawj ntse txawm tias cov neeg tshiab. Nws qhov kev ntsuas qhov tseeb ua tau raws li Karl Fischer titration cov qauv, nrog qhov kev ua yuam kev ntawm tsawg dua lossis sib npaug rau ± 3ug hauv 10ug-1000ug ntau thiab tsawg dua lossis sib npaug rau 0.3% rau cov qauv saum toj 1mg, qhia meej meej txog feeb hloov ntawm cov dej hauv cov roj insulating.
2. Kev lag luam-Tshwj xeeb zoo
Ua kom haum rau siab- cov khoom siv hluav taws xob hluav taws xob tu, HM401 nta txhim kho kev tiv thaiv- cuam tshuam tsim. Nws ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ntawm 10-35℃thiab txheeb ze cov av noo tsawg dua lossis sib npaug li 85%, ua kom haum rau ob qho tib si kev sim thiab kev sim ntsuas. Ua-hauv nkhaus spectrum tsom xam qhia tiag-lub sij hawm ya raws cov ntsiab lus, ua rau cov neeg ua haujlwm saib xyuas kom ntsuas cov roj sai sai. Txhawb kev tswj hwm cov txheej txheem thiab cov qauv ua piv txwv ntxiv / tso dej ua haujlwm kom ua haujlwm rau kev sim ua haujlwm thiab txhim kho kev sim ua haujlwm. Raws li cov khoom tseem ceeb ntawm nws tus kheej tsim los ntawm Goldhome, HM401 tau dhau los ua lub Hoobkas nruj thiab kev ntsuas kev ruaj ntseg kom xa cov kev daws teeb meem zoo rau kev ntsuas roj hauv kev lag luam hluav taws xob.
III. Lus Ceeb Toom Tseem Ceeb: Qhia meej txog qhov yuav tsum tau ua kom tsis txhob muaj kev nug txog cov khoom tsis raug
Thaum lub sij hawm sib tham txog cov cuab yeej siv tshuaj xyuas cov roj av noo, qee cov neeg siv khoom yuav ntsib cov lus pom zoo ntawm cov khoom tsis zoo vim tsis paub txog cov ntsiab lus thiab cov qauv kev qhia tshwj xeeb. Txhawm rau xyuas kom meej thiab ua haujlwm tau zoo, thov nco ntsoov cov hauv qab no:
1. Sib txawv ntawm kev tshawb nrhiav kom tsis txhob muaj kev ntxhov siab hauv kev xaiv tus qauv
Karl Fischer titration txoj kev tsuas yog tsim nyog rau kev kuaj xyuas cov kab ya raws (<0.5%). For samples with higher moisture content (>0.05%), xaiv lub volumetric Karl Fischer analyzer es tsis txhob HM401. Tsis tas li ntawd, tsis txhob cuam tshuam cov txheej txheem coulometric nrog rau lwm yam khoom siv ntsuas dej xws li distillation lossis centrifugal txoj kev. Cov txheej txheem sib txawv sib txawv heev hauv kev siv tau thiab qhov tseeb; kev xaiv yuav tsum yog raws li cov kev xav tau ntawm kev xeem tiag tiag.
2. Txheeb xyuas tus qauv Goldhome HM401 kom tsis txhob muaj cov khoom cuav lossis tsis sib xws
HM401 yog Goldhome tus qauv tshwj xeeb rau Karl Fischer titration -raws li roj taug qab ya raws nrhiav kom pom. Nws tsis yog npaj rau lwm yam kev xeem ntawv (xws li, dielectric poob, tawg voltage ntsuas). Thaum nug, cov neeg siv khoom yuav tsum tau hais meej meej "HMDQ HM401" thiab "Karl Kulen Titration Method Oil Moisture Tester" kom tsis txhob muaj kev ntxhov siab vim tsis meej pem cov npe lossis cov lus piav qhia ua haujlwm, uas yuav ua rau muaj kev nug txog cov khoom tsis raug (xws li, cov khoom ntsuas dej ntim lossis cov khoom cuav los ntawm lwm hom).
