Epsom Ntsev vs Magnesium Sulphate: Qhov Tseem Ceeb Qhov Sib Txawv & Kev Siv Khoom

Ntau tus neeg siv cov lus "Epsom ntsev" thiab "magnesium sulphate" sib hloov, tab sis muaj qhov sib txawv tseem ceeb ntawm ob qhov tseem ceeb rau cov neeg yuav khoom thiab kawg - cov neeg siv nkag siab. Thaum Epsom ntsev yog ib hom magnesium sulphate, tsis yog tag nrho magnesium sulphate yog Epsom ntsev. Kev nkag siab txog qhov sib txawv no pab xyuas kom meej tias cov khoom tsim nyog raug xaiv rau cov ntawv thov kev lag luam tshwj xeeb, zam cov teeb meem kev ua haujlwm thiab cov nqi tsis tsim nyog.

 

Epsom ntsev yog daim ntawv heptahydrate ntawm magnesium sulphate, txhais tau tias nws muaj xya dej molecules ib chav tsev ntawm magnesium sulphate. Nws feem ntau yog muag li dawb, crystalline crystals thiab feem ntau yog txuam nrog kev saib xyuas tus kheej thiab kev siv hauv tsev, xws li da dej ntsev, cov leeg nqaij, thiab ua vaj. Epsom ntsev muaj cov ntsiab lus magnesium qis (nyob ib ncig ntawm 10%) piv rau anhydrous magnesium sulphate thiab soluble hauv dej, ua rau nws yooj yim rau siv hauv tshuaj pleev ib ce thiab kev ua liaj ua teb.

 

Magnesium sulphate, ntawm qhov tod tes, yog ib lo lus dav dav uas suav nrog ob qho tib si anhydrous thiab heptahydrate cov ntaub ntawv. Anhydrous magnesium sulphate tsis muaj dej molecules thiab cov ntsiab lus magnesium ntau dua (kwv yees li 20%), ua rau nws muaj zog dua thiab tsim nyog rau kev lag luam siv qhov chaw, qhov hnyav, thiab magnesium concentration yog qhov tseem ceeb. Tsis zoo li Epsom ntsev, anhydrous magnesium sulphate yog qhuav, hmoov uas yog hygroscopic heev (absorb noo noo los ntawm huab cua).

 

Qhov sib txawv tseem ceeb ntawm Epsom ntsev thiab magnesium sulphate nyob hauv lawv daim ntawv, magnesium cov ntsiab lus, thiab kev siv. Epsom ntsev (heptahydrate) yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau solubility siab thiab qis magnesium concentration, xws li kev saib xyuas tus kheej, kev ua liaj ua teb (foliar sprays), thiab kev ua vaj tsev. Anhydrous magnesium sulphate, ntawm qhov tod tes, yog qhov zoo dua rau cov txheej txheem kev lag luam, xws li kev kho dej, tshuaj synthesis, hluav taws kub retardants, thiab bulk export, qhov twg siab magnesium concentration thiab tsis tshua muaj noo noo cov ntsiab lus yog qhov tseem ceeb.

 

Lwm qhov sib txawv tseem ceeb yog khaws cia thiab tuav. Epsom ntsev yog hygroscopic tsawg dua li anhydrous magnesium sulphate, ua rau nws ruaj khov dua thaum khaws cia thiab tsheb thauj mus los. Nws tsis tas yuav ntim tshwj xeeb los tiv thaiv kev nqus dej noo, ua kom yooj yim dua thiab tus nqi ntau dua - siv tau rau cov ntawv thov me me -. Tsis muaj dejmagnesium sulfate, txawm li cas los xij, yuav tsum tau muab khaws cia rau hauv qhov sib khi, noo noo- cov thawv pov thawj los tiv thaiv clumping thiab tswj nws cov purity, uas ntxiv rau kev tuav thiab khaws cov nqi.

 

Rau cov neeg yuav khoom lag luam, xaiv ntawm Epsom ntsev thiab magnesium sulphate nyob ntawm lawv daim ntawv thov tshwj xeeb. Yog tias solubility thiab yooj yim ntawm kev siv yog qhov tseem ceeb, Epsom ntsev (heptahydrate) yog qhov kev xaiv zoo dua. Yog tias siab magnesium concentration, qhov chaw ua haujlwm, lossis kev thauj khoom loj yog qhov tseem ceeb, anhydrous magnesium sulphate yog qhov tsim nyog. Los ntawm kev nkag siab txog qhov sib txawv tseem ceeb no, cov neeg yuav khoom lag luam tuaj yeem xaiv cov khoom tsim nyog kom ua tau raws li lawv cov kev xav tau, ua kom muaj kev ua tau zoo thiab tus nqi- ua tau zoo.
