Dab tsi yog qhov cuam tshuam rau kev ntsuas qhov ntsuas ntawm refractometer?
Refractive index yog ib txoj hauv kev yooj yim thiab raug rau kev txheeb xyuas qhov purity ntawm cov organic tebchaw. Rau ntau lub tshuab binary, muaj kev sib raug zoo ntawm qhov ntsuas qhov ntsuas thiab qhov sib xyaw ua ke, thiab yog li nws kuj tau siv los ua qhov ntsuas ntsuas cov khoom. Lub refractive index yog ib qho tseem ceeb ntawm cov khoom siv kho qhov muag ntawm cov ntaub ntawv pob tshab. Thaum lub refractive Performance index ntawm cov khoom ntsuas yog nyob nruab nrab ntawm 1.3000 thiab 1.7000, tag nrho cov kev xav txog txoj kev muaj qhov zoo ntawm kev yooj yim thiab ceev ceev, tsis tshua muaj kev xav tau rau ib puag ncig tej yam kev mob, thiab tsis xav tau lub teeb monochromatic. Abbe refractometer yog ib qho cuab yeej siv tag nrho txoj kev xav los ntsuas qhov ntsuas qhov ntsuas ntawm cov pob tshab lossis cov kua pob tshab. Kev ntsuas qhov ntsuas qhov ntsuas ntawm cov kua siv lub Abbe refractometer los txiav txim siab nws cov khoom muaj pes tsawg leeg yog ib qho ntawm cov kev siv tshuaj ntsuam xyuas thiab kev tshawb pom hauv kev tsim khoom thiab kev tshawb fawb xws li petrochemical thiab cov khoom noj khoom haus.
Yam cuam tshuam thiab tswj
kub
Ntawm qhov sib txawv ntawm qhov kub thiab txias, qhov ntsuas qhov ntsuas ntawm tib qhov nruab nrab yog qhov sib txawv, yog li nws yog qhov tsim nyog los sib piv cov refractive index ntawm cov xov xwm sib txawv raws li qhov kub thiab txias. Lub refractive index ntawm cov ntaub ntawv pob tshab yog ze ze rau lawv cov kub thiab muaj pes tsawg leeg. Feem ntau, qhov refractive index ntawm cov kuab tshuaj yog ntsuas nyob rau hauv qhov kub thiab txias ntawm ({0}}) degree . Lub Abbe refractometer yuav tsum tau khaws cia ntawm qhov sib thooj rau ob teev ua ntej nws tuaj yeem siv rau kev ntsuas.
Teeb meem lub teeb wavelength
Kev cuam tshuam ntawm kev tshaj tawm ntawm kev nthuav tawm ceev ntawm lub teeb ntawm qhov sib txawv wavelengths sib txawv, yog li ntsuas qhov ntsuas qhov ntsuas ntawm tib qhov nruab nrab siv qhov teeb meem teeb meem ntawm qhov sib txawv wavelengths txawv. Lub Abbe refractometer xaiv D-line 589.3mm ntawm sodium daj lub teeb raws li qhov teeb meem teeb los ntawm Amish dispersion prism
Cov kev xav tau rau qhov ntsuas qhov ntsuas ntawm cov khoom yuav tsum tau kuaj
Lub refractive index ntau yam khoom uas ntsuas tau los ntawm ib tug refractometer yog 1.30 ~ 1.70iii.
txheeb ze humidity
Qhov yuav tsum tau muaj rau cov av noo: Tus qauv ua haujlwm nkhaus ntawm lub refractometer nrog cov av noo ntawm tsawg dua 85 feem pua. Ua ntej, ntawm atmospheric siab thiab kub ntawm 30 degree, lub refractive index ntawm binary tov tov nrog sib txawv proportions thiab concentrations yog ntsuas los ntawm ib tug Abbe refractometer. Kev sib raug zoo ntawm cov molar muaj pes tsawg leeg ntawm cov tshuaj thiab cov refractive index yog txiav txim, thiab tus qauv nkhaus ntawm molar muaj pes tsawg leeg ntawm cov tshuaj thiab cov refractive index ntawm qhov kub thiab txias yog tau.
