Kev paub txog Refractometer
Lub refractometer, tseem hu ua refractometer, yog ib qho cuab yeej siv lub teeb los ntsuas qhov concentration ntawm cov kua. Nws yog siv los ntsuas qhov refractive index, birefringence, thiab optical zog. Lub refractive index yog ib qho tseem ceeb ntawm lub cev tsis tu ncua ntawm cov khoom. Ntau cov tshuaj ntshiab muaj ib qho kev ntsuas refractive. Yog hais tias cov khoom muaj impurities, lub refractive index yuav hloov, thiab yuav muaj deviations. Qhov ntau impurities, qhov ntau dua qhov sib txawv.
Refractometers feem ntau yog tsim los ntawm siab refractive index prisms (cov iav txhuas los yog cubic zirconia), prism tsom iav, lo ntsiab muag, nplai (cov nplais sab hauv lossis cov nplais sab nraud), thiab eyepieces.
Refractometers suav nrog tes tuav refractometers, qab zib refractometers, zib ntab refractometers, gemstone refractometers, digital zaub refractometers, tsis siv neeg refractometers thiab online refractometers.
Yuav ua li cas lub refractometer ua haujlwm
Lub hauv paus ntsiab lus: Thaum lub teeb nkag mus rau lwm qhov nruab nrab pob tshab los ntawm ib qho nruab nrab pob tshab, refraction tshwm sim, uas yog tshwm sim los ntawm qhov sib txawv ntawm lub teeb nyob rau hauv ntau yam xov xwm. Refractive index yog hais txog qhov sib piv ntawm qhov ceev ntawm lub teeb hauv huab cua mus rau qhov ceev hauv lwm yam khoom. Refractive index yog qhov sib piv ntawm qhov ceev ntawm lub teeb nyob rau hauv cov huab cua mus rau qhov ceev ntawm lub teeb nyob rau hauv lub ntsuas khoom los yog qhov ratio ntawm lub sine ntawm qhov teeb meem lub kaum sab xis mus rau lub sine ntawm lub refraction lub kaum sab xis thaum lub teeb hla los ntawm cov khoom ntsuas los ntawm huab cua nyob rau hauv lub sine. Cov xwm txheej ntawm sodium spectrum D kab thiab 20 degree .
Hais txog kev ua haujlwm, nws txais cov xim ua kua siv lead ua kua thiab kov vaj huam sib luag, thiab USB thiab LAN yog cov qauv sib txuas los tiv thaiv ntau yam khoom siv nthuav dav.
Refractometer txoj cai ntawm refraction
Yog tias koj muab xaum rau hauv ib khob dej, lub taub yuav tshwm nkhaus. Tom qab ntawd yog tias koj muab cov dej qab zib tso rau hauv lub khob thiab sim tib qhov kev sim, qhov ntxeev ntawm tus cwj mem yuav tsum tshwm sim ntau dua. Qhov no yog ib qho piv txwv ntawm qhov tshwm sim ntawm refractive index.
Lub refractometer tau muab tso rau hauv cov tswv yim siv vim yog kev saws los ntawm ib hom tshiab ntawm optical system. Lub solubility ntawm cov tshuaj ntsuam xyuas yog ntsuas los ntawm kev hloov cov kev sib raug zoo ntawm cov refractive index ntawm cov tshuaj thiab nws solubility. Thaum qhov ceev ntawm ib yam khoom nce, nws refractive index nce proportionally.
Refractometers siv txoj kev xav ntawm refraction uas lub prism tuav ib tug siab dua refractive index tshaj qhov kev ntsuam xyuas; los ntawm kev hloov dua siab tshiab los ntsuas qhov solubility lossis refractive index ntawm cov tshuaj ntsuam xyuas.
Thaum cov tshuaj ntsuam xyuas yog diluted, lub refractive Performance index ntawm cov tshuaj ntsuam xyuas yog siab dua li ntawm lub prism, yog li lub kaum sab xis ntawm refraction kuj loj.
Thaum cov tshuaj ntsuam xyuas yog qhov tuab, qhov ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas qhov ntsuas yog qis dua li ntawm lub prism, yog li lub kaum sab xis ntawm refraction yog me me.
Qhov muaj pes tsawg leeg ntawm refractometer
1. Lub teeb nkag nkag
2. Refractive prism
3. Zero adjustment ntsia hlau
4. Lub qhov muag
5. Lub tes tsho roj hmab 2. Yuav siv li cas
1) Thaum siv lub tes tuav refractometer, tuav lub tes tsho roj hmab nrog plaub ntiv tes ntawm sab laug tes thiab kho lub qhov muag nrog sab tes xis kom tiv thaiv lub cev kub los ntawm kev nkag mus rau qhov ntsuas thiab cuam tshuam qhov ntsuas qhov tseeb.
2) Qhib lub teeb inlet phaj thiab so lub refracting prism huv si nrog ib tug mos flannelette.
3) Muab ob peb tee dej distilled rau ntawm refracting prism, maj mam kaw lub teeb inlet phaj, thiaj li hais tias cov kev daws yog sib npaug zos rau ntawm qhov chaw ntawm lub prism, thiab tsom lub teeb inlet phaj ntawm lub teeb los yog qhov chaw kaj, thiab saib xyuas thaj tsam ntawm kev pom los ntawm lub qhov muag, yog tias txoj kab sib faib nruab nrab ntawm lub teeb thiab tsaus ntuj ntawm qhov pom tsis meej, tig lub qhov muag kom pom qhov pom tseeb, thiab tom qab ntawd tig lub xoom hloov ntsia hlau los teeb qhov kev faib. kab nruab nrab ntawm lub teeb thiab tsaus ntuj ntawm xoom. Tom qab ntawd so cov dej distilled thiab hloov nrog cov tshuaj ntsuam xyuas. Nyob rau lub sijhawm no, thaj chaw saib nyob ntawm txoj kab ciam teb, thiab qhov sib npaug ntawm qhov sib faib ntsuas tus nqi yog qhov concentration tus nqi thiab qhov ntom ntom ntawm cov tshuaj ntsuam xyuas.
4. Ceev faj Qhov ntsuas no yog qhov ntsuas qhov muag pom tseeb. Thaum siv thiab tu, cov khoom hauv qab no yuav tsum tau them rau:
1. Hauv kev siv, koj yuav tsum tau ceev faj thiab siv nws nruj me ntsis raws li cov lus qhia. Tsis txhob xoob qhov sib txuas ntawm qhov ntsuas qhov kev txiav txim siab, thiab tsis txhob poob, sib tsoo, lossis ua nruj ua tsiv.
2. Tom qab siv, nws yog nruj me ntsis txwv tsis pub muab tso rau hauv dej ncaj qha rau kev ntxuav. Nws yuav tsum tau wiped huv si nrog ib tug huv mos ntaub flannel dampened nrog dej. Qhov saum npoo ntawm qhov chaw kho qhov muag yuav tsum tsis txhob khawb lossis khawb.
3. Cov cuab yeej yuav tsum tau muab cia rau hauv qhov chaw qhuav, tsis muaj plua plav, tsis muaj roj thiab tsis muaj kua qaub kom tsis txhob muaj corrosion lossis mildew ntawm qhov chaw kho qhov muag.
