Sodium nitrate yog cov khoom siv dav siv hauv kev lag luam tshuaj. Nws cov mis molecular yog NaNO3, uas yog ib qho ionic compound uas muaj ib tug nitrogen oxide ion thiab ob sodium ions. Sodium nitrate muaj ntau yam siv hauv kev lag luam, vim nws tuaj yeem siv los ua cov khoom siv tshuaj lom neeg, nrog rau cov chiv thiab hmoov phom. Hauv tsab xov xwm no, peb yuav tham txog kev siv sodium nitrate hauv kev tsim khoom thiab lwm yam.
Cov khoom ntawm sodium nitrate
Nyob rau hauv lub crystal ntawm sodium nitrate, nitrogen oxide ions thiab sodium ions nyiam ib leeg los ua ionic muaju. Cov muaju ntawm sodium nitrate tshwm tsis muaj xim, dawb, los yog lub teeb daj, nrog lub cubic crystal qauv. Nyob rau hauv chav tsev kub, sodium nitrate tsis yooj yim volatile, tab sis yooj yim soluble hauv dej. Sodium nitrate daws tshwm tsis muaj xim lossis lub teeb daj, thiab nthuav tawm cov yam ntxwv ntawm cov tshuaj acidic, ua rau nws tsis muaj zog acid.
Kev siv ntawm sodium nitrate
Sodium nitrate yog ib qho tseem ceeb ntawm cov khoom nruab nrab hauv ntau cov txheej txheem tsim khoom. Nws tuaj yeem siv los ua tus neeg sawv cev nitrating hauv kev tsim cov kua qaub dyes, dye precursors, tshuaj tua kab, txuj lom, thiab tawg. Nws tseem tuaj yeem siv los tsim cov khoom siv roj hmab, cov tshuaj lom neeg cov tshuaj reagents, thiab cov pyrotechnic combustion pab, thiab tseem siv los ua coagulant, txo tus neeg sawv cev, thiab oxidant koom nrog cov organic synthesis.
Sodium nitrate kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tu qhov chaw ntawm cov ntaub ntawv xws li tooj liab oxide thiab nyiaj phaj. Sodium nitrate yog ntxiv rau cov tshuaj ntxuav cov kua qaub, tso cai rau cov lag luam los daws qhov nyuaj los ntxuav qhov chaw yam tsis tas yuav siv cov tshuaj ntxuav hnyav heev.
Sodium nitrate kuj tau siv dav ua chiv hauv kev ua liaj ua teb. Sodium nitrate fertilizer yog ib qho zoo nitrogen chiv uas tuaj yeem txhawb cov cag ntoo loj hlob thiab txhim kho qoob loo thiab zoo los ntawm kev ntxiv sodium nitrate rau hauv av. Hauv qee lub tebchaws, sodium nitrate fertilizer tuaj yeem siv los hloov cov compost los txhim kho cov av fertility thiab txo cov pa phem ib puag ncig.
Sodium nitrate kuj tau siv dav hauv kev tsim cov foob pob hluav taws thiab foob pob hluav taws, nrog rau hauv kev tsim phom thiab phom phom. Hauv cov foob pob hluav taws thiab foob pob hluav taws, sodium nitrate ua cov oxidant tuaj yeem txhawb kev tawg thiab tawg. Hauv kev npaj cov mos txwv rau cov phom thiab phom, sodium nitrate yog ib qho tseem ceeb ntawm cov khoom tawg, muab lawv lub zog puas tsuaj.
