Potassium nitrate rau cov nroj tsuag yog cov xim tsis muaj xim lossis cov hmoov dawb thiab tsis deliquescence hauv huab cua. Lub melting kub yog 2.11g / cm3 ntawm 334 degree, thiab decomposes rau poov tshuaj nitrite thiab oxygen ntawm 338 degree los yog siab dua. Lub solubility ntawm poov tshuaj nitrate txo qis nrog qhov nce ntawm nitric acid concentration, thiab nce thaum tus nqi qis tshaj yog mus txog, thiab solubility ntawm poov tshuaj nitrate hauv dej nce nrog qhov kub thiab txias. Cov khoom muaj tsawg kawg yog 46.0% potassium oxide thiab 13.5% nitrogen.
Cov txheej txheem ntau lawm
1. Neutralization txoj kev
Txoj kev no neutralizes poov tshuaj nitrate thiab dej los ntawm neutralization ntawm nitric acid thiab potassium hydroxide.
2. Ammonium nitrate conversion method (txoj kev decomposition nyuaj)
Ammonium nitrate thiab potassium chloride yog decomposed los tsim poov tshuaj nitrate. Cov khoom lag luam yog ammonium chloride.
3. Ion txauv txoj kev
Los ntawm kev siv ion exchange resin los yog zeolite, poov tshuaj chloride thiab nitrate yog siv los ua raw cov ntaub ntawv thiab cov cation txauv resin muaj ib tug heev adsorbability rau poov tshuaj ammonium ion. Los ntawm cov nyhuv ntawm cation txauv resin, poov tshuaj ammonium chloride thiab nitrate tov nyob rau hauv cov tshuaj ntawm poov tshuaj chloride thiab nitrate hloov mus rau ib leeg nyob rau hauv lub ion exchange resin, thiab poov tshuaj nitrate tov yog tau.

Daim ntawv thov
Potassium nitrate rau cov nroj tsuag yog ib qho tseem ceeb chlorine-free potassium nitrogen compound fertilizer. Txog 75% ntawm lub ntiaj teb cov poov tshuaj nitrate yog siv rau hauv kev ua liaj ua teb chiv, poov tshuaj nitrate rau kev ua liaj ua teb yog cov chiv zoo, thiab tsis muaj qhov seem tom qab siv, nws yog cov chiv zoo rau cov qoob loo chlorine xws li haus luam yeeb, kas fes, txiv lws suav, txiv hmab txiv ntoo. , citrus, tshuaj yej nplooj, thiab lwm yam Potassium nitrate tsis yog tsuas yog muaj cov ntsiab lus ntawm cov poov tshuaj, tab sis kuj muaj nitrogen-potassium compound chiv, dej solubility zoo, tsis muaj acidity ntawm cov tshuaj, yooj yim rau absorbed los ntawm cov nroj tsuag, haum rau tej qoob loo thiab tej lub caij.
