Fertilizer Prilled Urea
Urea muaj ammonia tsw thiab qab ntsev. Thaum tshav kub kub yog siab tshaj nws melting point,
Nws yog decomposed rau hauv biuret, ammonia thiab cyanic acid. 1g soluble hauv 1mL dej, 10ml 95% ethanol, 1ml 95%
Boiling ethanol, 20mL anhydrous ethanol, 6ml methanol thiab 2mL glycerol. Soluble nyob rau hauv concentrated hydrochloric
acid, yuav luag insoluble hauv ether thiab chloroform. pH ntawm 10% aqueous tov yog 7.23. Kab mob.

Ureayog siv nyob rau hauv kev tsom xam rau antimony thiab tin. Kev txiav txim siab ntawm txhuas, calcium, tooj liab, gallium, phosphorus, iodide thiab
nitrate. Kev txiav txim siab ntawm cov ntshav urea nitrogen, nrog rau kev daws teeb meem, kev txiav txim siab ntawm cov ntshav bilirubin. Kev cais ntawm
hydrocarbons. Nitric oxide thiab nitrous acid siv los decompose nitrogen hauv kev tsom xam. Npaj qhov nruab nrab. Folin
Txoj kev rau kev txiav txim siab ntawm uric acid stabilizer, homogeneous nag lossis daus.
Lub cev muaj zog: Tsis muaj xov tooj cua dawb, dawb ntws, dawb los ntawm cov khoom tsis zoo coated, kheej kheej & zoo ib yam, 100% kho tiv thaiv caking.
Kev Siv: Nws yog siv ncaj qha los ua chiv lossis raw khoom ntawm NP / NPK chiv. Nws tseem yog qhov chaw ntawm polywood, Adblue, Yas, Resin, Pigment, Pub additive thiab Tshuaj Kev Lag Luam.
Pob: nyob rau hauv tej, hauv 50kg / 1,000kg woven hnab lined nrog puab hnab yas raws li cov neeg thov.
1. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm granular urea yog nws cov solubility siab hauv dej thiab ntau yam cawv, ua rau nws yooj yim rau kev thov thiab ua kom muaj txiaj ntsig zoo ntawm cov as-ham los ntawm cov nroj tsuag.
2. Nws versatility thiab compatibility nrog ntau daim ntawv thov txoj kev xws li kev tshaj tawm, kev hnav khaub ncaws saum toj kawg nkaus los yog fertigation ua rau nws yog thawj qhov kev xaiv rau cov neeg ua liaj ua teb tab tom nrhiav kom zoo dua kev tswj cov chiv.
3. cov tshuaj muaj pes tsawg leeg ntawmgranular urea, nrog rau nws cov decomposition mus rau hauv biuret, ammonia thiab cyanic acid ntawm qhov kub thiab txias, qhia txog nws lub peev xwm rau kev tswj kev tso tawm thiab kev cuam tshuam ntev rau cov khoom noj khoom haus. Qhov no ua rau nws zoo tagnrho rau cov khoom noj khoom haus tas mus li thoob plaws lub caij cog qoob loo, txo qhov kev xav tau ntawm kev rov ua dua tshiab.
1. Hauv kev ua liaj ua teb, kev siv cov chiv yog qhov tseem ceeb los txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv thiab ua kom cov qoob loo ntau tshaj plaws.
2.Granular urea muaj ib qho txawv ammonia thiab qab ntsev thiab yog nitrogen-nplua nuj chiv uas ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev loj hlob ntawm cov nroj tsuag. Thaum siv rau hauv av, nws dhau los ua cov txheej txheem hydrolysis, tso ammonium ions uas yooj yim absorbed los ntawm cov hauv paus hniav. Qhov no nce nitrogen uptake, yog li txhawb cov qoob loo loj hlob thiab kev loj hlob.
3.Hauv kev ua liaj ua teb, kev siv cov chiv yog qhov tseem ceeb los txhawb kev loj hlob ntawm cov nroj tsuag noj qab haus huv thiab ua kom cov qoob loo ntau tshaj plaws.
