I-Urea, ekwabizwa ngokuba yi-Urea okanye i-carbamide, inefomula yekhemikhali i-ch4n2O okanye i-conbun, i-hitrogen, ioksijini, kunye ne-hystal emhlophe. Enye yezinto eziluncedo ezilula zeyona mveliso iphambili ye-nitrogen ene-nitrogen ye-metabolism ye-metabolism kunye nokuhombisa kwizilwanyana ezincancisayo kunye neentlanzi ezithile. Njengesichumisi esingathathi hlangothi, urea ulungele imihlaba eyahlukeneyo kunye nezityalo. Kulula ukuyigcina, ilungele ukusebenzisa, kwaye inefuthe elincinci elitshabalalisayo emhlabeni. Sisichumisi se-nitrogen yekhemikhali esinexabiso elikhulu lokusetyenziswa kunye nomxholo ophezulu we-nitrogen. I-Urea iyaqengqeleka phantsi kweemeko ezithile zisebenzisa i-ammonia kunye nekharbon diokside kwishishini.
Urea unokusabela nge-AIDS ukuba yenze ityuwa. Ine-hydrolysis. Kwiqondo lobushushu eliphakamileyo, ukufundisa ngenjongo kunokwenziwa ukuze kufuneke i-chauret, i-triuret, kunye ne-cyaniric acid. Ubushushu ukuya kwi-160 ℃ ye-Demoration, ukuvelisa igesi ye-ammonia kwaye uyiguqulele ibe ye-casonate. Kuba le nto ikhona kumchamo womntu, kubizwa ngokuba nguIrea. I-Urea iqulethe i-46% initrogen (n), eyona nto iphakamileyo ye-nitrogen phakathi kwezichumisi eziqinileyo zenitrogen.
I-Urea inokuthi i-hydrolyze ivelise i-ammonia kunye nekharbon diokside phantsi kwesenzo see-asidi, iziseko, kunye ne-enzymes (Acids kunye neziseko zifuna ukufudumeza).
Ukungazinzi kwe-shirmal, ukufudumeza ukuya kwi-150-160 ℃ iya kongamela i-chauret. I-Copper Sulfate iphinda iphindwe nge-chairest kumbala omfusa kwaye inokusetyenziselwa ukuchonga urea. Ukuba ivutha ngumsindo ngokukhawuleza, iya kuncitshiswa kwaye inqamleze ukuba yenze i-cyclic compling emithandathu ye-cyclic efihlakeleyo, i-SCyanic Acid.
I-AcetyLherea kunye ne-Diacetylika inokuveliswa ngokuphendula nge-acetyl chloride okanye i-acetic adhydride.
Phantsi kwesenzo se-sodium ethanol, iphendula nge-Diegyyl Maloni ukuba ivelise i-malonylurea (ebizwa ngokuba yi-barbiric acid, ngenxa ye-aciditye yayo).
Phantsi kwesenzo seAlkaline Catallspes enjenge-ammonia, inokusabela nge-formaldehyde kunye ne-urea ye-urealdehyde iphinde yenziwa.
Yenza i-hydrazne hydrate yokuvelisa i-amnouar.

1. Ukuba i-Urea igcinwe ngokungafanelekanga, kulula ukuyifumana umswakama kunye ne-chump, echaphazela umgangatho we-Urea kwaye obangela ilahleko ethile yezoqoqosho kumafama. Oku kufuna ukuba amafama agcine i-IERA ngokuchanekileyo. Ngaphambi kokusetyenziswa, kuyimfuneko ukugcina ingxowa ye-Urea ye-Urea ye-UNCACS. Ngexesha lokuhamba, kufuneka ithathelwe ingqalelo ngononophelo, ikhuselwe kwimvula, igcinwe kwindawo eyomileyo, enomoya enomoya kunye neqondo lobushushu eliphantsi kwe-20 ℃.
2. Ukuba igcinwe izixa ezikhulu, iibhloko zokhuni kufuneka zisetyenziselwe ukuthwala emazantsi kangangeesentimitha ezingama-20, kwaye kufanele kubekho umsantsa weesentimitha ezingaphezulu kwe-50 phakathi kwendawo ephezulu kunye nophahla lokungasebenzi. Isicatshulwa kufuneka sishiywe phakathi kwezitokhwe. Ukulungiselela ukuhlolwa kunye nokungena umoya. Ukuba i-Urea esele ivuliwe ayisetyenziswanga, kuyimfuneko ukutywina umlomo webhegi ngexesha elifanelekileyo ukulungiselela ukuba usetyenziswe kunyaka olandelayo.
3. Kulumkele ukunxibelelana nolusu kunye namehlo.
Isichumisi: Iipesenti ezingama-90 ze-Urea ezivelisiweyo zisetyenziswa njengesichumisi. Yongezwa emhlabeni kwaye ibonelela nge-nitrogen kwizityalo. I-irect ephantsi (ngaphantsi kwe-0.03%) i-urea isetyenziswa njengesichumisi se foliaar. Inyibiliza emanzini kwaye ifakwe kumagqabi kwezityalo, ngakumbi iziqhamo kunye neCitrus.
I-Ireatilizer inenzuzo yokubonelela ngomxholo ophakamileyo we-nitrogen, obaluleke kakhulu kwimetabolism yesityalo kwaye inxulumene ngqo nenani leziqu kunye namagqabi afumana ukukhanya kwefotosinthes. Ukongeza, i-nitrogen ikhona kwiivithamini kunye neeproteni, kwaye inxulumene nomxholo weprotheyini.
I-Urea isetyenziswa ngeendlela ezahlukeneyo zezityalo. Ukuchumisa imfuneko kuba umhlaba uphulukana ne-nitrogen eninzi emva kokuvunwa. Amasuntswana asetyenziswayo asetyenziswa emhlabeni, ekufuneka esebenza kakuhle kwaye abe sisityebi kwi-bacteria. Isicelo singenziwa ngexesha lokutyala okanye ngaphambili. Emva koko, u-Urea uHydrolyzed kwaye ehluthiwe.
Inkathalo kufuneka ithathwe xa kusenziwa isicelo se-Urea emhlabeni. Ukuba isetyenziswa kumphezulu, okanye ukuba ayifakwanga emhlabeni ngokusetyenziswa okufanelekileyo, imvula, okanye ukunkcenkceshela, i-ammonia iya kuphulukana nelahleko kubaluleke kakhulu. Ukunqongophala kwe-nitrogen kwizityalo kubonakaliswa ngokwehla kwindawo yegqabi kunye nokwehla komsebenzi we-photosynthetic.
Ukuchumisa amagqabi: Ukuchumisa amagqabi ngumsebenzi wakudala, kodwa ngokubanzi, ukusetyenziswa kwezakha mzimba ezinxulumene nomhlaba kuncinane, ngakumbi ngokwezimali ezinkulu. Nangona kunjalo, ezinye iirekhodi zamanye amazwe zibonisa ukuba ukusetyenziswa kwe-urea ephantsi ku-Urea kunciphisa isixa sezichumiso sisetyenzisiwe emhlabeni ngaphandle kokusebenza kakuhle, ubukhulu kunye nomgangatho weziqhamo. Uphando lubonakalisile ukuba ukutshiza kwe-foliar ngenani elincinci le-urea kusebenza njengomhlaba wokutshiza. Ukongeza kwizicwangciso zokuchumisa ezomeleleyo, oku kusebenza ngokuqhelekileyo kusetyenziswa izichumisi ngokudibeneyo nezinye iichemicals zezolimo.
Iikhemikhali kunye nePlastiki: I-Urea ifumaneka kwiPlastives, iPlastic, i-Inks, i-inki, amayeza, kunye neearhente zamaphepha, kunye nezinyithi.
Imfuyo yokutya imfuyo: Urea uxutywe kwinkomo yokondla kwaye unike i-nitrogen, ebaluleke kakhulu ekuqulunqweni kweprotein.
Imveliso yokuphelisa: I-Ugcini formaldehyde Retin kunye nezinye ii-resins zinezicelo ezahlukeneyo kumzi mveliso, njengemveliso ye-plywood. Ziyasetyenziswa nakwiicosmetics kunye neepeyinti.
I-cheswin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ze-chydrocarbons kunye neechimi zemichiza kubathengi bemizi-mveliso.Ngaphambi koko, nceda ufunde le ngcaciso ilandelayo malunga neshishini kunye nathi:
1. Ukhuseleko
Ukhuseleko yinto yethu ephambili. Ukongeza ekunikezeleni abathengi ngolwazi malunga nokusetyenziswa okukhuselekileyo nokusingqongileyo kweemveliso zethu, sizibophelela ekuqinisekiseni ukuba umngcipheko wokukhuseleka kwabasebenzi kunye neekhontrakthi zincitshiswa ubuncinci kwaye zincitshiswe ubuncinci bezinto ezifanelekileyo. Ke ngoko, sifuna ukuba umthengi aqinisekise ukuba imigangatho yokhuseleko efanelekileyo kwaye ifezekisiwe ngaphambi kokuba ihanjiselwe (nceda ujonge kwisihlomelo se-HISCEXIX ngokwemigaqo ngokubanzi yentengiso engezantsi). Iingcali zethu ze-HZE zinokubonelela ngesikhokelo kule migangatho.
I-2. Indlela yokuhambisa
Abathengi banoku-odola kwaye bahambise iimveliso ezivela kwiComwin, okanye banokufumana iimveliso kwisityalo sethu semveliso. Iindlela ezikhoyo zothutho zibandakanya ilori, uloliwe okanye izithuthi ezininzi (iimeko ezahlukeneyo ziyasebenza).
Kwimeko yeemfuno zabathengi, sinokuchaza iimfuno zebhanti okanye iitanki kwaye zisebenzise imigangatho yoKhuseleko eKhuseleko / yokuPhononongwa kunye neemfuno.
