1. Kev Kho Mob
Kev siv cov tshuaj noj muaj qee cov tshuaj muaj urea kom nce cov tawv nqaij noo noo. Kev hnav khaub ncaws sib khi siv rau qhov tsis yog
Kev phais Ntsia Rauv Hloov muaj 40% urea. 2. Cheeb tsam ua liaj ua teb
Urea yog qhov siab siab nitrogen fertilizer, uas yog nruab nrab sai ua yeeb yam chiv thiab tseem tuaj yeem ua tau
siv los tsim ntau cov compound chiv. Tsis muaj cov tshuaj phem tseem nyob hauv av, thiab lub sijhawm ntev ntev tsis muaj teebmeem tsis zoo. Cov tsiaj cov tsiaj tuaj yeem siv los ua cov ruminants.3. Kev tiv thaiv thiab tswj cov kab tsuag
Tom qab sib xyaw nrog urea, cov tshuaj ntxhua khaub ncaws, thiab dej hauv qhov sib piv ntawm 4: 1: 400, nws tuaj yeem tiv thaiv cov txiv ntoo, zaub, thiab paj rwb, nrog cov tshuaj ntxuav tawm ntawm ntau dua 90%.
4. Urea hlau chiv
Urea cov ntaub ntawv chelated hlau nrog fe 2+ hauv daim ntawv ntawm ib txoj. Cov organic hlau chiv muaj tus nqi qis thiab a
Cov nyhuv zoo ntawm kev tiv thaiv kev tiv thaiv hlau tsis txaus thiab ntsuab. 5. Pub tshuaj ntxiv
Qhov tsis txaus ntseeg ntawm tib neeg cov zaub mov thiab protein kuj tseem ua rau muaj kev sib tw loj hauv kev lag luam pub.
Kev lag luam nquag nrhiav cov khoom tshiab thiab nthuav mus rau nitrogen cov peev txheej tshaj cov protein, xws li urerogen urea. 6. Kev lag luam thaj chaw
Nws tuaj yeem siv rau hauv cov khoom muaj ntau li cov khoom siv raw rau ntau lawm cov khoom lag luam xws li melamine,
urea formendehyde cob, hydrazine hydrate, tetralycline, txo qis xim daj br, Phalocyanine B, Phthalocyanine BX, Monosodium Glutamate, thiab lwm yam. 7. Daim ntawv thov hauv Tshuaj pleev ib ce
Urea yog ib qho txiaj ntsig cov dej noo uas muaj nyob hauv stratum ntawm cov tawv nqaij ntawm daim tawv nqaij thiab yog qhov loj

Cov cuab yeej tshuaj
|
Urea tuaj yeem hnov mob nrog cov kua qaub los ua cov ntsev. Nws muaj cov nyhuv nruab hydrolysis. Thaum kub siab, kev ua kom pom kev cuam tshuam tuaj yeem nqa tawm los tsim biuret, triuret, thiab cyanuric acid. Thaum tshav kub kub mus rau 160 degree rau kev rhuav tshem, tsim cov roj ammonia thiab hloov nws mus rau hauv Isocyanate. Vim tias cov tshuaj no nyob hauv tib neeg cov zis, nws npe urea. Urea muaj 46% nitrogen (n), uas yog cov nitrogen zoo tshaj plaws hauv cov khoom noj nitrogen chiv.

1. Ua ntej siv, nws yog qhov tsim nyog los khaws cov urea ntim hnab lawm thiab tsis muaj kev puas tsuaj. Thaum lub sijhawm thauj mus los, nws yuav tsum tau daws nrog kev saib xyuas, tiv thaiv los ntawm nag, thiab muab ventilated qhov chaw nrog kub hauv qab no 20 degree.
2. Yog khaws cia rau hauv cov chaw loj, cov ntoo yuav tsum tau siv rau cushion hauv qab ntau dua 50 cm, thiab muaj kev sib txawv ntawm ntau dua 50 cm, thiab muaj kev sib tw kom yooj yim dim pa thiab noo noo dissipation. Ib zaj yuav tsum tau sab laug ntawm cov pawg. Txhawm rau pab txhawb kev tshuaj xyuas thiab dim pa.
3. Zam kev sib cuag nrog tawv nqaij thiab qhov muag.
