Molecular Luj: 60.05
Khoom siv:Urea
Related lus:nitrogen rau vaj zaub, urea yog cov organic chiv, Urea chiv rau cov nroj tsuag
Cov mis mos molecular:CH4N2O
Molecular Luj:60.05
Khoom:Cov organic sib xyaw ua ke ntawm carbon, nitrogen, oxygen, thiab hydrogen yog siv lead ua dawb. Ib qho ntawm cov organic tebchaw yooj yim tshaj plaws yog lub ntsiab nitrogen-muaj cov khoom kawg ntawm cov protein metabolism hauv cov tsiaj txhu thiab qee cov ntses. Nws tseem yog cov chiv nitrogen uas muaj cov ntsiab lus siab tshaj nitrogen.
Raws li ib tug nruab nrab fertilizer, urea yog haum rau txhua yam av thiab nroj tsuag. Nws yog ib qho yooj yim rau khaws cia, siv tau yooj yim, kev puas tsuaj rau cov av me me, yog qhov loj ntawm kev siv tshuaj nitrogen chiv tam sim no. Hauv kev lag luam, ammonia roj thiab carbon dioxide yog siv los ua ke urea nyob rau hauv qee yam mob
Daim ntawv thov
Urea yog siv los ua lub hauv paus chiv thiab topdressing, thiab qee zaum ua cov noob chiv. Ua ntej kev hloov pauv ntawm urea yog lub xeev molecular, tsis tuaj yeem adsorbed los ntawm cov av, yuav tsum tiv thaiv nrog dej poob.
Urea siv tau rau tag nrho cov qoob loo thiab tag nrho cov av, tuaj yeem siv tau los ua cov chiv chiv thiab tshuaj pleev ib ce, cov paj qhuav tuaj yeem siv tau.
Urea (nitrogen chiv) tuaj yeem txhawb kev faib tawm ntawm tes thiab kev loj hlob, ua rau cov nplooj ntoo loj hlob luxuriantly. Nws tuaj yeem siv los ua raw khoom rau melamine, urea formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, Caffeine, Txo Brown Br, Phthalocyanine B, Phthalocyanine Bx, monosodium glutamate thiab lwm yam khoom.

Cia:
1. Yog tias qhov khaws cia ntawm urea tsis tsim nyog, nws yooj yim rau nqus dej noo thiab caking, uas yuav cuam tshuam rau qhov zoo ntawm urea thiab coj qee qhov kev lag luam poob rau cov neeg ua liaj ua teb. Nco ntsoov khaws lub hnab urea kom zoo ua ntej siv, tuav maj mam thaum lub sijhawm thauj mus los, los nag pov thawj, thiab khaws cia rau hauv qhov chaw qhuav, qhov cua zoo nrog qhov kub hauv qab 20 degrees.
2. Yog tias nws muaj ntau qhov chaw cia, cov hauv qab no yuav tsum siv cov ntaub ntawv ntoo txog li 20 cm, sab sauv thiab lub ru tsev kom tawm ntau tshaj 50 cm ntawm qhov chaw, txhawm rau txhawm rau kom muaj cua thiab noo noo, nruab nrab ntawm pawg thiab pawg. tawm ntawm txoj kev. Rau kev soj ntsuam thiab qhov cua. Twb tau qhib lub hnab urea yog tias tsis siv, yuav tsum muab lub hnab ntim rau lub sijhawm, thiaj li yuav siv tau rau xyoo tom ntej.
Ntim:25/50KG woven hnab lined nrog cov hnab yas, lossis raws li cov neeg siv khoom xav tau.

FAQ
Q1: Puas yuav muaj cov tshuaj phem hauv kev siv cov khoom no mus ntev?
A: Tsis muaj teeb meem tshuaj nyob hauv av, thiab daim ntawv thov mus ntev tsis muaj kev cuam tshuam.
Q2: Kuv yuav tsum xyuam xim rau dab tsi thaum siv cov khoom no?
A: Urea yog cov organic nitrogen chiv, los ntawm cov av urease, hydrolyzed rau hauv ammonium carbonate lossis ammonium bicarbonate, tuaj yeem nqus tau los ntawm cov qoob loo. Yog li ntawd, urea yuav tsum tau siv 4 mus rau 8 hnub ua ntej cov qoob loo xav tau chiv. Cov khoom no tsis tuaj yeem ua cov noob chiv, yub chiv thiab nplooj chiv. Urea hydrolysis tsim ammonium nitrogen, thiab daim ntawv thov nto yuav ua rau ammonia volatilization, tshwj xeeb tshaj yog nyob rau hauv alkaline av. Yog li ntawd, urea yuav tsum tau siv tob rau hauv cov av, thiab cov nplej teb yuav tsum tau siv tob rau hauv cov txheej uas txo qis.
