Khoom Txheej Txheem

Urea, tseem hu ua urea lossis carbamide, muaj tshuaj organic ch4n2o lossis co (NH2) 2. Nws yog hydrogen, thiab yog ib tug dawb siv lead. Ib qho ntawm cov organic yooj yim yog lub ntsiab nitrogen-muaj cov khoom kawg ntawm cov protein metabolism thiab decomposition hauv cov tsiaj thiab qee cov ntses. Ua ib qho nruab nrab chiv, urea haum rau ntau cov av thiab nroj tsuag. Nws yog ib qho yooj yim los khaws cia, yooj yim siv, thiab muaj kev cuam tshuam me me rau cov av. Nws yog tshuaj nitrogen fertilitilizer nrog cov nqi ntau thiab cov ntsiab lus nitrogen ntau tshaj plaws. Urea yog synthesized nyob rau hauv qee qhov xwm txheej uas siv ammonia thiab carbon dioxide hauv kev lag luam.

Tus cwj pwm

Urea tuaj yeem hnov mob nrog cov kua qaub los ua cov ntsev. Nws muaj 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 ℃ rau kev txiav txim siab, 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 siab tshaj plaws ntawm cov khoom noj nitrogen chiv.
Urea tuaj yeem hydrolyze los tsim cov ammonia thiab carbon dioxide nyob rau hauv qhov kev txiav txim ntawm kev txiav txim ntawm cov acids, lub hauv paus, thiab cov kua qaub thiab hauv paus yuav tsum tau cua sov).
Rau thermal instabilability, cua sov rau 150-160 ℃ yuav tiv thaiv biuret. Tooj liab sulfate reacts nrog biuret nyob rau hauv ib tug xim xim thiab tuaj yeem siv los txheeb xyuas urea. Yog tias nrawm nrawm, nws yuav yog cov neeg ua kom zoo nkauj thiab trimeric los ua tus qauv canclic sib txuas, cyanuric acid.
Acetylurea thiab diacetylenyfurea tuaj yeem tsim los ntawm kev siv nrog acetyl chloride lossis acetic anhydride.
Raws li qhov kev txiav txim ntawm sodium ethothol, nws reacts nrog diohlal malonate los tsim Malonhlurea (tseem hu ua Barituric Acid, vim nws cov acidity).
Nyob rau hauv qhov kev txiav txim ntawm alkaline catalysts xws li ammonia, nws tuaj yeem hnov mob nrog formaldehyde thiab condense mus rau urea formaldehyde cob.
Hnov mob nrog hydrazine hydrate los tsim aminourea.

Torage Txuj Ci

1. Yog hais tias urea tau khaws cia tsis raug, nws yog ib qho yooj yim los nqus noo noo thiab pob, cuam tshuam rau cov thawj urea thiab ua rau qee qhov kev lag luam poob rau cov neeg ua liaj ua teb. Qhov no yuav tsum tau cov neeg ua liaj ua teb los khaws urea kom raug. Ua ntej siv, nws yog qhov tsim nyog los khaws cov urea ntim hnab lawm. Thaum lub sijhawm thauj mus los, nws yuav tsum tau daws nrog kev saib xyuas, tiv thaiv los ntawm nag, thiab muab tso rau hauv qhov chaw qhuav, zoo siv nrog kub hauv qab no 20 ℃.
2. Yog tias nws tau khaws cia rau hauv cov chaw loj, cov ntoo yuav tsum tau siv rau Cushion hauv qab thiab muaj ntau dua li 50 centimeters, thiab yuav tsum muaj kev sib txawv ntawm qhov chaw siab dua thiab noo noo tsis txaus ntseeg. Ib zaj yuav tsum tau sab laug ntawm cov pawg. Txhawm rau pab txhawb kev tshuaj xyuas thiab dim pa. Yog tias urea uas twb qhib lawm tsis raug siv lawm, nws yog qhov tsim nyog los tuav lub hnab ntim lub qhov ncauj raws sijhawm siv rau lwm xyoo.
3. Zam kev sib cuag nrog tawv nqaij thiab qhov muag.

Aerosol tshuaj tsuag

Chiv: 90% ntawm cov urea tsim yog siv los ua chiv. Nws yog ntxiv rau cov av thiab muab cov nitrogen rau cov nroj tsuag. Tsawg biuret (tsawg dua 0.03%) urea yog siv los ua cov foliar fertilizer. Nws yog soluble hauv dej thiab thov rau nplooj ntawm cov nroj tsuag, tshwj xeeb txiv hmab txiv ntoo thiab citrus.
Reasea fertilizer muaj qhov kom zoo dua ntawm kev muab cov ntsiab lus nitrogen, uas yog ncaj qha rau cov nroj tsuag metabolism thiab nplooj uas nqus lub teeb rau photosynthesis. Ib qho ntxiv, nitrogen yog tam sim no nyob rau hauv cov vitamins thiab cov protein, thiab muaj feem xyuam rau cov protein cov ntsiab lus.
Urea siv nyob rau hauv ntau hom qoob loo. Kev uaert yog tsim nyog vim tias cov av tsis muaj txiaj ntsig ntawm cov nitrogen tom qab sau. Urea hais tau siv hauv av, uas yuav tsum ua haujlwm tau zoo thiab muaj kev nplua nuj nyob hauv cov kab mob. Daim ntawv thov tuaj yeem ua thaum cog lossis ua ntej. Tom qab ntawd, area yog hydrolyzed thiab decomposed.
Yuav tsum tau saib xyuas thaum thov urea kom raug rau cov av. Yog tias nws siv nyob rau saum npoo, lossis yog tias nws tsis tau koom rau hauv av los ntawm kev siv tsim nyog, dej nag, lossis dej tsis zoo uas yaj tau zoo heev. Cov tsis muaj nitrogen hauv cov nroj tsuag tau pom nyob rau hauv ib qho kev txo qis hauv thaj chaw thiab txo qis hauv Photosynthetic kev ua si.
Nplooj Qaus: nplooj chiv yog qhov kev coj ua ib txwm, tab sis feem ntau hais lus, siv cov av uas muaj cov av me me, tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm cov nyiaj loj. Txawm li cas los xij, qee cov ntaub ntawv thoob ntiaj teb qhia tias kev siv cov tshuaj urea tsawg thov kom cov av tsis muaj kev cuam tshuam, loj thiab txiv hmab txiv ntoo ua tau zoo. Kev tshawb fawb tau pom tias cov neeg txau uas muaj tshuaj tsuag me me ntawm urea yog qhov ua tau zoo ib yam li av txau. Ntxiv nrog rau cov phiaj xwm fertilization zoo, qhov no ua tau cov kev coj ua ntawm kev siv chiv ua ke nrog lwm cov tshuaj ua liaj ua teb.
Tshuaj lom neeg thiab cov ntaub ntub dej: urea yog tam sim no hauv cov nplaum, cov yas, cov inks, thiab cov neeg sawv cev, thiab cov ntawv sib dhos, thiab cov hlau.
Cov zaub mov noj tau haus: urea tau sib xyaw ua ke rau hauv nyuj pub thiab muab cov nitrogen, uas yog qhov tseem ceeb rau kev tsim cov protein.
Resin Production: urea formaldehyde cob thiab lwm yam Resins muaj ntau cov ntawv thov hauv kev lag luam, xws li plywood ntau lawm. Lawv tseem siv hauv cov tshuaj pleev ib ce thiab cov xim pleev xim rau.
