Calcium nitrate (calcium nitrate) yog crystalline, zoo heev, dawb compound uas tsis muaj ntxhiab.
Cov tshuaj no yog hygroscopic heev thiab yaj yooj yim hauv dej. Nws yuav tsum raug sau tseg tias calcium nitrate tuaj yeem ua kom sai sai. Hauv qhov no, peb hom crystalline hydrates yog tsim. Nws qhov tsis zoo tseem ceeb yog cov cuab yeej ntawm caking. Qhov no yuav tsum tau coj mus rau hauv tus account kom tsim nyog cia. Yog li, calcium nitrate yuav tsum muab cia rau hauv cov pob tshwj xeeb kaw (polypropylene hnab).
Nws tseem yuav tsum tau muab sau tseg tias nyob rau hauv ib txwm muaj qhov sib xyaw no yog hluav taws kub thiab tawg-pov thawj, tsis-flammable thiab ruaj khov nyob rau hauv -60 - +155 ° C, tab sis thaum ua hauj lwm nrog nws, koj yuav tsum siv tag nrho, ib yam nkaus. raws li cov khoom siv tiv thaiv tus kheej.
Calcium nitrate: daim ntawv thov
Calcium nitrate muaj 15% nitrogen thiab 26% CaO, uas tso cai rau nws siv dav hauv kev ua liaj ua teb kom them nyiaj rau qhov tsis muaj cov ntsiab lus hauv av, nrog rau kev pub zaub mov.
txaus nitrogen concentration yog tsim nyog rau kev loj hlob ntawm nplooj nplooj,synthesis ntawm amino acids, proteins thiab chlorophyll. Calcium yog lub luag haujlwm rau kev tsim cov hlwb tshiab, pab txhawb lub cev thiab cov hauv paus hniav ntawm cov nroj tsuag. Muab qhov no, calcium nitrate yog siv rau yellowing ntawm nplooj thiab lawv curling rau hauv ib lub ringlet, cov tsos ntawm punctate necrosis nyob rau hauv daim ntawv ntawm me me puag ncig tsaus xim av me ntsis, raws li zoo raws li rau ib tug qaug zog paus system, nws lwj thiab cessation ntawm cov nroj tsuag qia. kev loj hlob. Tsis tas li ntawd, kev siv cov chiv no tiv thaiv kev loj hlob ntawm paj paj xaus rau hauv txiv lws suav, nrog rau kev kub nyhiab ntawm nplooj lettuce. Nws tseem tsim nyog sau cia tias calcium nitrate, thaum siv rau cov av acidic, tshem tawm ntau tshaj ntawm cov hlau thiab manganese.
Calcium nitrate yog siv rau hauv daim ntawv ntawm cov kua hauv paus lossis foliar hnav khaub ncaws. Nyob rau hauv rooj plaub no, drip irrigation systems, tshwj xeeb installation, hose, kiv cua los yog knapsack sprayers yuav siv tau. Kuv yuav tsum hais tias tus qauv ntawm kev ua haujlwm ntawm calcium nitrate feem ntau lees txais thiab nyob ntawm hom hnav khaub ncaws saum toj kawg nkaus thiab hom nroj tsuag.
Nws tseem yuav tsum tau muab sau tseg tias calcium nitrate yog ib qho physiological alkaline chiv, yog li nws tuaj yeem siv rau txhua hom av. Nws tsis tuaj yeem ua ke nrog cov superphosphate yooj yim, tab sis nws raug tso cai ua ke calcium nitrate nrog lwm cov chiv tam sim ua ntej siv. Tom qab ua haujlwm tiav lawm, ntxuav koj lub ntsej muag thiab txhais tes kom huv si nrog xab npum thiab dej.
Kuv yuav tsum hais tias calcium nitrate tsis yog siv los ua chiv rau cov nroj tsuag xwb. Nws kuj yog ib qho admixture rau pob zeb, uastso cai rau koj kom nce nws lub zog loj. Tsis tas li ntawd, qhov sib xyaw no tiv thaiv kev txhim kho corrosion, tiv thaiv cov khoom siv hauv tsev los ntawm qhov kub thiab txias, yog siv rau hauv kev tsim cov tub yees brine, ntau yam reagents thiab fiberglass, thiab kuj yog ib qho tseem ceeb ntawm cov khoom tawg.
