Vim li cas cov txheej txheem coulometric rau Oil Moisture Tester hauv cov khoom siv roj yog tus qauv kub?
Karl Fischer titration method yog thawj zaug luam tawm los ntawm German chemist Karl Fischer nyob rau hauv 1935. Tus thawj txoj kev siv volumetric titration mus txog rau thaum lub coulometric version tau tsim nyob rau hauv 1959, tshwj xeeb tshaj yog rau kev txiav txim ntawm cov kab ya raws.
Cov khoom siv tseem ceeb muaj xws li microprocessor, dual-circuit balanced titration system, thiab anti-leakage electrolytic cell. Nws koom ua ke tsis siv neeg calibration, cov ntaub ntawv khaws cia (ntau tshaj 1000 nkag), tso saib ntawm electrolytic curves, thiab thermal printing functions. Los ntawm kev hloov kho tsis siv neeg ntawm cov hluav taws xob tam sim no (0-430mA) thiab cov cuab yeej saib xyuas lub sijhawm tiag tiag, nws ua rau kev txiav txim siab sai ntawm cov qauv noo noo, thiab txhawb nqa khoom, kua, thiab gaseous qauv compatibility.
Cov kev ceev faj yuav tsum tau ua dab tsi thaum siv?
1) Cov qauv yuav tsum tau kos siv lub syringe qhuav kom tsis txhob ya raws ntawm huab cua (txoj kev coulometric yog rhiab rau ambient humidity).
2) Ketone- thiab aldehyde- muaj cov roj ua rau cov tshuaj methanol, ua rau kev nyeem ntawv tsis tseeb; Tshwj xeeb Karl Fischer (KF) reagents los yog qhov cub txoj kev yuav tsum tau siv xwb.
3) Ua ib qho nyiaj npliag drift (siv tsawg dua 10 feeb) txhua zaus lub ntsuas hluav taws xob tau siv los ua kom lub hauv paus ruaj khov.

Dab tsi yog cov teeb meem tshwj xeeb thiab cov kev daws teeb meem cuam tshuam nrog kev ntsuas cov dej hauv cov khoom siv roj?
Roj qauv insoluble nyob rau hauv reagent
Roj yog ib yam uas tsis yog -cov organic polar thiab yog immiscible nrog Karl Fischer reagents (polar solvents)
Siv roj- cov tshuaj reagents uas muaj chloroform, hexane, lossis xylene; nce stirring siv
Nyuaj txhaj tshuaj siab -cov roj viscosity
viscosity ntawm iav roj, roj, thiab lwm yam, tuaj yeem ncav cuag 100,000
Kub cov qauv inlet (60 degree) kom txo viscosity; siv ib tug dav - tho syringe; dilute nrog hnyav ua ntej txhaj tshuaj
Kev cuam tshuam los ntawm cov roj additives
Qee cov tshuaj tua kab mob antioxidants thiab cov tshuaj ntxuav tes yuav raug cuam tshuam nrog Karl Fischer reagents
Siv ketone-raws li reagents (pyridine-cov tshuaj dawb) kom txo qis kev phiv; optimize qhov kawg kev txiav txim algorithm
Puas yog kev saib xyuas tau ua ib zaug los txo cov nqi?
Txhua hnub: Hloov cov molecular sieve ziab raj; xyuas cov xim electrolyte (hloov yog tias nws tsaus).

Cov neeg siv khoom siv roj Moisture Tester nyob qhov twg?
1) Cov tuam txhab hluav taws xob / cov chaw tsim hluav taws xob: Cov dej noo ntau dhau hauv cov roj transformer yog thawj qhov ua rau dielectric tawg; ASTM D1533 yog qhov yuav tsum tau xeem.
2) Roj manufacturers / lubricant distributors: ASTM D6304 yuav tsum lubricant noo noo cov ntsiab lus yuav tsum tau<200–500 ppm.
3) Petrochemical / Pharmaceutical industries: Cov dej noo hauv cov kuab tshuaj, esters, thiab lithium- ion roj teeb electrolytes yuav tsum yog<30–100 ppm.
4) Thib peb-cov chaw kuaj sim tog: Siv rau ISO 17025 kev lees paub; yuav tsum tau traceable calibration cov ntaub ntawv.
FAQ
Q1: Dab tsi yog qhov txawv ntawm txoj kev coulometric thiab volumetric?
A: The coulometric method generates iodine via in-situ electrolysis and is suitable for trace water levels ranging from 1 ppm to 0.1%; the volumetric method relies on a burette and is suitable for moisture content >0.1%. Transformer roj tsom xam yuav tsum siv txoj kev coulometric (ASTM D1533).
Q2: Dab tsi ntawm precision (hauv ppm) tuaj yeem ua tiav?
A: Cov cuab yeej muaj qhov rhiab heev ntawm 0.1 ug, tso cai rau kev kuaj pom qhov txwv ntawm 0.1 ppm rau 1 mL roj qauv. Kev ntsuas qhov tseeb ntawm cov qauv dej hauv thaj tsam 10-100 ug qhia qhov sib txawv ntawm Tsawg dua lossis sib npaug rau ± 1 ug, ua tau raws li tus qauv tsawg dua lossis sib npaug rau 10 ppm rau cov roj tshiab.
Q3: Nws puas ua raws li cov qauv thoob ntiaj teb?
A: Nws ua raws li ASTM D1533 (cov roj insulating), ASTM D6304 (cov khoom siv roj av), IEC 60814, GB / T 7600, thiab SH / T 0246 .
