Txoj kev PurificationPotassium Nitrate

Tam sim no invention nthuav tawm ib txoj kev purification rau poov tshuaj nitrate. Vim nws cov khoom tshwj xeeb, kev siv cov khoom siv potassium nitrate tau siv dav hauv ntau yam kev lag luam.

Ua raws li cov kauj ruam hauv qab no: dissolving 68-78 qhov chaw los ntawm qhov hnyav ntawm potassium nitrate khoom uas muaj impurities nyob rau hauv 32-44 qhov chaw los ntawm qhov hnyav ntawm dej, cua sov kom txog thaum cov tshuaj boils; Khaws cov tshuaj npau npau, ntxiv 5-8 qhov chaw los ntawm qhov hnyav ntawm precipitant, thiab kho tus nqi pH ntawm cov tshuaj mus rau 8-11. Do thiab hnov ​​​​mob rau 1-3 teev, tom qab ntawd cia nws sawv ntsug rau 0.8–1.5 teev kom tau txais cov tshuaj potassium nitrate los ntawm cov kua dej sib cais. Crystallize thiab qhuav cov tshuaj poov tshuaj nitrate kom tau cov poov tshuaj nitrate crystals. Txoj kev no tuaj yeem tau txais ntau dua-purity potassium nitrate piv rau cov txheej txheem recrystallization, uas ua rau muaj kev purity ntau dua 99.5% rau cov khoom siv poov tshuaj nitrate.

Muaj ntau yam kev siv cov khoom siv poov tshuaj nitrate, xws li kev tsim phom phom, hlau vuam pab, hluavtaws ammonia catalysts, iav khoom, ceramics, thiab lwm yam.

Keeb kwm

Potassium nitrate yog ib qho tseem ceeb ntawm cov khoom siv raw khoom. Kev siv cov poov tshuaj nitrate yog dav siv hauv kev tiv thaiv hauv tebchaws, kev lag luam tub rog, kev lag luam, kev ua liaj ua teb, khoom noj khoom haus additives, tshuaj, pub additives, optical iav, hluav taws xob kev lag luam, thiab lwm yam.
