Concentration ntawm zib mu thiab nws ntsuas

Baume degree, tseem hu ua zib ntab degree, yog chav tsev ntawm cov zib ntab, tab sis nws tau ceeb toom tshwj xeeb tias Baume degree tsis yog feem pua! Baume degree yog lwm chav tsev ntawm lub ntiajteb txawj nqus ntawm zib mu, thaum zib mu concentration yog hais txog feem pua ​​ntawm soluble solids nyob rau hauv zib mu. Qhov siab dua qhov concentration ntawm zib mu, ntau dua qhov tshwj xeeb gravity. Qhov concentration yog proportional rau Baume degree. Cov neeg hu ua Baume degree ntawm zib mu raws li qhov concentration ntawm zib mu hauv kev ua haujlwm tiag tiag, uas tau dhau los ua lub npe qub. Ob leeg sib txawv, tsis yog tib lub tswvyim.

Qhov concentration ntawm zib mu tuaj yeem txiav txim siab los ntawm Baume meter txoj kev, uas yog:

Kauj Ruam 1: Muab cov qauv coj mus kuaj rau hauv 500ml siab ntsuas lub tog raj kheej thiab nteg nws tiaj;

Kauj Ruam 2: Ntxig qhov qhuav thiab huv si Baume meter rau hauv cov qauv kawm tiav lub tog raj kheej thiab cia nws tog lawm;

Kauj Ruam 3: Thaum Baume meter tsis tso dej lawm, nyeem cov nplai tus lej nthuav tawm rau saum npoo ntawm cov qauv. Thaum cov qauv ntsuas kub yog 20 degree, qhov ntsuas tus naj npawb nthuav tawm ntawm qhov chaw yog qhov tseeb concentration tus lej;

Kauj Ruam 4: Cov concentration ntawm cov qauv tuaj yeem nce lossis txo los ntawm 0.0477 Baume degrees rau txhua 1 degree nce lossis txo qis hauv cov qauv ntsuas kub.

Lwm txoj kev yog siv lub tes tuav refractometer (raws li cov zib ntab refractometer qhia hauv qab) los ntsuas qhov concentration ntawm zib mu. Lub tes tuav refractometer feem ntau ntsuas nws cov ntsiab lus qab zib, thiab hloov nws cov concentration raws li qib qab zib cov ntsiab lus.
