Potassium Nitrate Dissolution

Yuav siv li cas

Kev tswj qhov kub ntawm qhov yuav tsum tau muaj cov kua dej txaus yog lwm qhov tseem ceeb ntawm qhov kev sim no, vim tias qhov kev sib cais ntawm cov poov tshuaj nitrate tau cuam tshuam rau qhov kub thiab txias. Tsis tas li ntawd, nrog rau cov ntsuas ntsuas dav dav thiab qhov tseeb calibration (tshwj xeeb tshaj yog distiller's grain thermometers), qhov kub ntawm ob lossis peb degrees saum toj no lossis qis dua yog qhov txaus los cuam tshuam rau kev suav cov txiaj ntsig.

(1) Yog li thaum lub sijhawm sim, nws raug nquahu kom ntsuas tus pas ntsuas kub, zoo dua los txheeb xyuas qhov yuam kev hauv tus pas ntsuas kub.

(2) Raws li cov khoom siv hluav taws xob zoo ntawm nitric acid bait yaj hauv dej, nws tuaj yeem yaj ncaj qha los npaj cov tshuaj saturated ntawm qhov kub thiab txias hauv lub caij ntuj no ntawm chav tsev kub (peb sim siv 10 milliliters dej distilled ntawm dej kub ntawm 15 tons). Dissolve nitric acid qe nyob rau hauv nruab nrab thiab tau ib tug saturated tov ntawm ib tug kub ntawm txog

Them mloog

Thaum muaj cov poov tshuaj nitrate dissolution, yuav tsum xyuam xim rau dab tsi

(1) tsuas yog ntsuas qhov ntsuas kub tsawg. Ntawm qhov kub thiab txias, cov dej kub hauv lub raj ntsuas yuav tsum ncav cuag qhov xav tau qhov kub thiab txias tas li ua ntej ntxiv KN0 muaju thiab nplawm nrog iav pas nrig.

(2) Nco ntsoov tias tom qab potassium nitrate dissolution, nws yog ib qho tsim nyog yuav tsum cia nws sawv ntsug li ob peb feeb kom ntseeg tau tias qhov sib npaug sib npaug mus txog ua ntej nchuav cov tshuaj. Thiab xyuam xim rau kev tswj qhov kub ntawm qhov ntsuas kub thaum lub sij hawm sawv ntsug.

(3) Qhia cov tub ntxhais kawm kom tsis txhob do nrog tus pas ntsuas kub, thiab nws yog qhov zoo tshaj kom tsis txhob ntxig tus pas ntsuas kub rau hauv cov pob zeb uas seem rau kev ntsuas kub.

(4) Thaum ntsuas qhov kub siab tshaj hauv chav tsev kub, sai li sai tau thaum lub raj xa dej tawm hauv chav da dej, qhov kub thiab txias tam sim ntawd poob thiab crystallization tshwm sim. Yog li ntawd, qhov kev txiav txim pouring ntawm cov tshuaj yuav tsum ceev ceev kom tsis txhob muaj qhov kub thiab txias sib txawv ntawm cov kua dej thiab cov tshuaj qub.

(5) Txoj kab uas hla ntawm lub raj xa mus siv yuav tsum loj dua, thiab lub raj ntsuas yuav tsum tsis txhob ntev dhau. Thawj qhov teeb meem ntawm '1978 Shenxue Technology' pom zoo siv 100-ml beaker los tuav dej da dej. Peb xav tias siv lub raj mis me me rau kev ua dej da dej tsis yooj yim, thiab cov nyhuv tsis zoo vim qhov nyuaj ntawm insulating cov dej da dej siv lub beaker me me.
