DMF Density piav qhia: Ib qho tob tob saib ntawm qhov ntom ntom ntawm Dimethylformamide
1. DMF yog dab tsi?
DMF, lub npe hu ua Suav Dimethylformamide (Dimethylformamide), yog cov xim tsis muaj xim, pob tshab thiab tsis tshua muaj hygroscopic kua siv dav hauv kev lag luam tshuaj, tshuaj, hluav taws xob thiab textile. Nws muaj cov solubility zoo thiab tuaj yeem yaj ntau yam organic thiab inorganic, yog li nws ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev lag luam.
2. Lub ntsiab lus tseem ceeb ntawm DMF ceev
Qhov ntom yog qhov piv ntawm huab hwm coj mus rau qhov ntim ntawm cov khoom, feem ntau yog qhia raws li qhov loj ntawm ib chav tsev ntim. Hauv kev lag luam tshuaj, nws yog ib qho tseem ceeb kom nkag siab txog qhov ceev ntawm DMF raws li nws cuam tshuam ncaj qha rau kev ntsuas, thauj thiab siv cov khoom siv.Qhov ceev ntawm DMF feem ntau qhia hauv g / cm³ lossis kg / m³. Ntawm qhov ntsuas kub (20 ° C), DMF muaj qhov ceev ntawm kwv yees li 0.944 g / cm³. Tus nqi no yuav txawv me ntsis nyob ntawm qhov kub thiab txias.
3. Qhov cuam tshuam ntawm qhov kub thiab txias ntawm DMF ceev
Qhov kub thiab txias muaj qhov cuam tshuam loj rau DMF ntom ntom. Raws li qhov kub thiab txias, qhov ceev ntawm DMF feem ntau txo qis. Qhov no yog vim qhov ceev molecular txav ntawm cov kua, uas ua rau muaj qhov sib txawv ntawm cov molecules thiab yog li tsawg dua ib chav tsev ntim. Rau cov ntawv thov kev lag luam, nws yog ib qho tsim nyog yuav tsum nkag siab qhov kev hloov pauv ntawm qhov ntom ntom ntawm DMF ntawm qhov sib txawv. Piv txwv li, thaum ua cov tshuaj tiv thaiv ntawm qhov kub thiab txias, qhov kev hloov ntawm DMF ceev yuav tsum raug coj mus rau hauv tus account kom ntseeg tau tias qhov tseeb metrological.
4. Kev cuam tshuam ntawm DMF ceev ntawm cov ntawv thov kev lag luam
DMF qhov ntom ntom muaj qhov cuam tshuam tseem ceeb hauv cov ntawv thov kev lag luam. Piv txwv li, DMF feem ntau yog siv los ua cov kuab tshuaj hauv kev npaj tshuaj. Nws qhov ceev cuam tshuam rau tus nqi thiab concentration ntawm cov kuab tshuaj, uas nyob rau hauv lem cuam tshuam qhov zoo thiab purity ntawm cov khoom kawg. Hauv kev tsim tshuaj lom neeg, qhov ntom ntawm DMF kuj muaj feem xyuam rau cov khoom thauj thiab khaws cia. Kev nkag siab txog qhov ceev ntawm DMF tuaj yeem pab txhim kho cov txheej txheem thiab txo cov nqi tsim khoom.
5. Yuav ntsuas qhov ceev ntawm DMF li cas?
Txhawm rau kom tau txais qhov tseeb ntawm DMF, kev ntsuas siv lub ntsuas qhov siab densitometer lossis lub raj mis tshwj xeeb yog tsim nyog. Nyob rau hauv ib qho chaw kuaj mob, qhov ntsuas kub tsis tu ncua thiab cov qauv ntshiab yuav tsum tau tswj xyuas kom ntseeg tau qhov kev ntseeg tau ntawm kev ntsuas ntsuas. Hauv kev lag luam ib puag ncig, kev saib xyuas lub sijhawm tiag tiag kuj tuaj yeem ua tiav nrog on-line densitometer kom cov txheej txheem tsis tuaj yeem hloov kho raws sijhawm.
6 Cov ntsiab lus
DMF ntom ntom yog ib qho tseem ceeb ntawm lub cev muaj zog ntawm dimethylformamide, ib qho tseem ceeb ntawm cov tshuaj, thiab kev nkag siab thiab kev paub txog nws cov yam ntxwv ceev yog qhov tseem ceeb rau kev tsim tshuaj thiab kev siv tshuaj. Los ntawm kev ntsuas qhov tseeb thiab kev tshawb fawb, peb tuaj yeem siv DMF zoo dua los txhim kho kev tsim khoom thiab ua kom cov khoom zoo. Hauv cov xwm txheej sib txawv ntawm kev lag luam, kev hloov pauv ntawm qhov ntom ntawm DMF tuaj yeem ua rau muaj kev cuam tshuam sib txawv, yog li nws tseem ceeb heev uas yuav tsum muaj kev nkag siab tob thiab tswj nws.
Los ntawm kev soj ntsuam saum toj no, peb tuaj yeem pom tau tias kev paub txog kev hloov pauv txoj cai thiab kev ntsuas ntawm DMF ntom ntom yog lub hauv paus rau kev ua kom muaj kev vam meej ntawm cov txheej txheem tsim tshuaj. Vam tias tsab xov xwm no tuaj yeem pab koj nkag siab zoo dua qhov tseem ceeb ntawm DMF ntom ntom thiab muab kev siv rau koj cov khoom tsim thiab kev tshawb fawb.
