Kev Txij Nkawm thiab Kev Kho Mob Ntawm Nitrogen Taag Flasks

Lub Nitrogen Rabk yog ib qho tseem ceeb ntawm Kjeldahl Nitrogen Analyzer, thiab nws txij nkawm yog qhov ua haujlwm ib txwm muaj ntawm qhov ntsuas thiab qhov tseeb ntawm qhov ntsuas tau. Cov hauv qab no yog cov hau kev tshwj xeeb rau kev tswj hwm nitrogen flasks:

1. Ib feem kev ntxuav
Nquag tu lub nitrogen rabas yog ib kauj ruam tseem ceeb heev. Tom qab siv, yaug tam sim ntawd nrog cov kais dej kom tshem cov khoom seem thiab reagents kom huv si nrog distilled dej lossis qhuav kom tiv thaiv kom tsis txhob muaj kua.
2. Tshawb xyuas huab cua thiab dej ntws
Txawm hais tias ntu no yog tsom xam rau kev saib xyuas ntawm tag nrho cov Kjeldahl Nitrogen Analyzer, nws yog tsis muaj huab cua lossis dej sib txuas nrog cov roj nitrogen. Kev tshuaj xyuas cov kab hluav taws xob no rau kev laus lossis kev puas tsuaj, thiab hloov kho qhov teeb meem twg.
3. Zam kev kub siab thiab ncaj qha tshav ntuj
Cov raj nplaim hluav taws xob yuav tsum muab tso rau hauv ib puag ncig nrog cov ntsuas kub ruaj khov thiab av noo. Feem ntau, qhov kub yuav tsum tau tswj ntawm 15-35 degree thiab cov av noo yuav tsum yog nruab nrab ntawm 40% {2}}%. Nyob rau tib lub sijhawm, cov flask yuav tsum tau zam ntawm kev tso rau hauv tshav ntuj ncaj qha lossis hauv ib cheeb tsam uas txias dhau los yog kev tiv thaiv kev ua haujlwm lossis kev ua tsis tau zoo.
4. Kev tuav tom qab siv sijhawm ntev
Tom qab siv ntev, kev ntsuas hluav taws xob yuav tshwm sim ntawm lub rhaub, uas tuaj yeem txo qhov ua cua sov. Cov Descaling tsis tu ncua: tua lub zog thaum lub tshuab hluav taws xob chav hluav taws xob raug muab tua thiab tshem cov ntsaws rau saum lub zog hluav taws xob. Ntxig ib qho me me funnel thiab txhaj tiv thaiv tus neeg saib xyuas mob siab los yog glacial acetic acid (diluted sulfuric acid kuj tseem siv tau) kom huv cov nplai. Qhib lub qhov cub Valve ntawm lub hau hluav taws xob sab hauv cov chassis, ntws cov dej ua kom tiav, thiab tom qab ntawd yaug nrog cov dej huv ntau zaus.
5. Kev ua kom huv
Nquag ntxuav lub alkali tov tank thiab boric acid tank los xyuas kom meej tias tsis muaj kev txuam nrog ntawm sediment. Ntxuav cov thoob los tiv thaiv impurities los ntawm kev cuam tshuam qhov tseeb ntawm cov qauv tshuaj xyuas.
6. Kev nyab xeeb ceev faj
Thaum tuav cov flasces nitrogen, tsim nyog cov cuab yeej ntawm tus kheej tas li, nrog cov khaub ncaws antifrois, los tiv thaiv tus kheej ntev los ntawm kev phom sij ntawm cov tshuaj lom neeg.
Thaum siv cov khoom siv hluav taws xob ruaj khov, ua kom muaj kev nyab xeeb zoo hauv ib puag ncig ib puag ncig kom tiv thaiv cov roj teeb meem thiab cov kev pheej hmoo muaj kev noj qab haus huv.
Los ntawm kev ua raws li kev saib xyuas txij nkawm sab saud, lub neej kev pabcuam ntawm cov nitrogen freat tuaj yeem txuas ntxiv, thiab qhov tseeb thiab kev ntseeg tau ntawm cov ntaub ntawv sim tuaj yeem ua kom tiav. Ib qho ntxiv, kev saib xyuas yuav tsum tau them nyiaj rau kev ua haujlwm raws li cov lus qhia muab los ntawm cov khw kom ua tiav cov nyhuv zoo tshaj plaws.
