Potassium Nitrate nta

Ib qho tseem ceeb ntawm cov poov tshuaj nitrate yog nws lub peev xwm los ua lub zog oxidizer. Qhov no txhais tau hais tias nws tuaj yeem hnov ​​​​mob nrog lwm yam tshuaj los pab txhawb cov tshuaj lom neeg uas yuav nyuaj lossis tsis yooj yim sua. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo hauv ntau yam khoom sib txawv, suav nrog cov chiv, foob pob hluav taws, thiab foob pob hluav taws.

Lwm qhov tseem ceeb ntawm potassium nitrate yog nws solubility hauv dej. Qhov no ua rau nws yooj yim rau yaj thiab sib tov nrog lwm yam tshuaj, ua rau nws muaj cov khoom xyaw hauv ntau hom khoom sib txawv. Nws solubility kuj ua rau nws yooj yim rau siv nyob rau hauv nws cov ntshiab daim ntawv, tsis tas yuav tsum tau rau elaborate ua los yog refining cov tswv yim.

Potassium nitrate kuj yog ib qho chaw ruaj khov, txhais tau hais tias nws tsis decompose los yog tawg yooj yim thaum lub sij hawm. Qhov kev ruaj ntseg no ua rau nws muaj kev ntseeg siab hauv ntau daim ntawv thov sib txawv, los ntawm kev khaws zaub mov mus rau kev ua hlau.

Yuav siv li cas

Cov tshuaj muaj pes tsawg leeg ntawm cov as-ham yuav tsum nyob ntawm cov qoob loo cog. Ntxiv ntau cov chiv chiv rau 1000 litres dej melon: 800g potassium nitrate, 900g calcium nitrate, 150g dihydrogen phosphate, 500g magnesium sulfate, thiab 200g potassium dihydrogen phosphate. Cov chiv chiv muaj xws li 15g ntawm ferrous sulfate, 0.5g ntawm tooj liab sulfate, 2g ntawm manganese sulfate, thiab 0.2g ntawm zinc sulfate. Solanaceae: Ntxiv 600g ntawm poov tshuaj nitrate, 480g ntawm calcium nitrate, thiab 500g ntawm magnesium sulfate rau 1000 liv dej, nrog cov kab lus zoo ib yam li melons. Lwm cov qoob loo zaub: Ntxiv 400g ntawm poov tshuaj nitrate, 1000g ntawm calcium nitrate, 137g ammonium sulfate, 550g magnesium sulfate, thiab 150g ntawm poov tshuaj dihydrogen phosphate rau 1000 liters dej, nrog cov kab lus zoo ib yam li melons.

Them mloog

Thaum lub sij hawm kev loj hlob ntawm cov zaub, acidity thiab alkalinity ntawm cov as-ham uas tswj los ntawm lub lumbar qaum yog nyob nruab nrab ntawm 5 thiab 6.5. Ua ntej npaj cov kev daws teeb meem, siv lub ntsuas acidity los yog daim ntawv ntsuas pH. Thaum tus nqi pH siab dhau lawm, kho nws nrog sparse acid lossis phosphoric acid; Thaum tus nqi pH qis dhau, kho nws nrog dilute ammonia dej los yog caustic soda tov.

Thaum lub sij hawm kev loj hlob, qhov kub ntawm 15 thiab 25 degrees. Ntxiv cov as-ham thaum sawv ntxov thiab yav tsaus ntuj rau hnub kub thiab thaum tav su hauv lub caij ntuj no. Ntxiv 1-2 zaug hauv ib hnub, txhua zaus thov 1.2–1.5 kilograms ntawm cov as-ham rau ib square meter. Kev ywg dej txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm kev cog qoob loo tsis muaj av. Kev ywg dej yuav tsum tau ua thaum nruab nrab ntawm kev siv cov khoom noj khoom haus, feem ntau ib zaug thaum sawv ntxov thiab yav tsaus ntuj, 4-5 zaug hauv ib hnub nyob rau lub caij ntuj sov, thiab ob zaug hauv lub caij ntuj no. Tus nqi ntawm cov dej yog kwv yees li 2 kilograms ib square meter ib zaug.
