(Ubungakanani bereferensi yesicelo 'ukusetyenziswa kwemveliso')
① Ukubunjwa, umlingiswa kunye nomxholo wezondlo ziyafana, ukukhutshwa kwezondlo kunye nemodi yokufunxa iyafana, kwaye umxholo wamanzi, ukuqina, umxholo wothuli kunye nokuthuthwa kunye nokugcinwa kokugcinwa kwamasuntswana ahlukeneyo.
② Izinga lokuchithwa, izinga lokukhutshwa kwezondlo kunye nezichumisi zeengqungquthela zihluke, kwaye izinga lokuchithwa kwamancinci amancinci ngokukhawuleza kwaye umphumo ukhawuleza; Ukunyibilika kwamasuntswana amakhulu kucotha kwaye ixesha lokuchumisa lide.
③ Umxholo we-urea biuret enkulu ingaphantsi kuneencinci ezincinci, ezisetyenziswa njengesichumisi esisisiseko, okanye iinqununu ezinkulu zisetyenziselwa ukuveliswa kwezichumisi ezixutywe. Ukulungiswa komphezulu, i-urea encinci yegranular isetyenziselwa ukutshiza ngamahlamvu, ukufaka umngxuma, ukufaka umsele kunye nokuchumisa, kunye nokugungxulwa kwamanzi.
④ I-particle enkulu ye-urea inothuli oluphantsi xa kuthelekiswa ne-particle-particle urea, amandla aphezulu acinezelayo, i-fluidity enhle, inokuthuthwa ngobuninzi, akulula ukuyiqhekeza kunye ne-caking, kwaye ifanelekile ukuchumisa ngoomatshini.

Ukusetyenziswa kweMveliso
Ulawulo lokuchumisa
[Uhlengahlengiso lwesixa seentyatyambo] Ukuze uphumelele unyaka omkhulu kunye nomncinci wentsimi ye-apile, ukutshiza i-0.5% yesisombululo se-urea emanzini kwiiveki ezi-5-6 emva kokutyatyamba (ixesha elibalulekileyo lokwahlukana kwentyatyambo ye-apula, ukukhula kwamahlumela amatsha kuyacotha okanye kuyeka, kunye nomxholo we-nitrogen wamagqabi ubonisa ukuhla), ukutshiza kabini ngokulandelelana, kunokunyusa umthamo we-nitrogenc wentyatyambo, ukukhula kwentyatyambo ye-nitrogen. ukwahlula, kwaye wenze isixa seentyatyambo sonyaka omkhulu ngokufanelekileyo.
[Intyatyambo neziqhamo ziyancipha] Izitho zeentyatyambo zepesika zinovakalelo ngakumbi kwi-urea, kodwa ukusabela kucotha, ngoko ke ipesika yangaphandle kunye novavanyo lwe-urea, iziphumo zibonisa ukuba intyatyambo yepesika kunye ne-nectarine kunye neziqhamo zincinci, zidinga ugxininiso olukhulu (7.4%) ukubonisa iziphumo ezilungileyo, ugxininiso olufanelekileyo luyi-8% -12%, iiveki ezi-1-2 emva kokutshiza, ukuphumeza injongo yentyatyambo kunye neziqhamo zokunciphisa iziqhamo.
[Imveliso yembewu yerayisi] Kubuchwephesha bemveliso yembewu yerayisi exutyiweyo, ukwenzela ukuba kuphuculwe izinga lokuwela kwabazali, ukuze kwandiswe isixa semveliso yembewu yerayisi exutyiweyo okanye isixa sokuchuma semigca eyinyumba, umfuniselo wenziwa nge-urea endaweni yegibberellin, kunye nokusetyenziswa kwe-1.5% ukuya kwi-2% ye-urea kwinqanaba lokukhulelwa kunye nenqanaba lokuqala lendlebe (20% ye-earfertility effect), i-20% ye-earfertility effect ayizange iphumelele. ukwandisa ukuphakama kwesityalo.
[Abalawuli berhorho] Nge urea, ukuhlamba umgubo, amanzi 4: 1:400, emva kokuxuba, kunokuthintela imithi yeziqhamo, imifuno, iintwala zomqhaphu, izigcawu ezibomvu, izinambuzane ikhaphetshu kunye nezinye izinambuzane, isiphumo insecticidal ngaphezu kwe-90%. [Isichumiso sentsimbi ye-Urea] I-Urea yenza i-iron echelated nge-Fe2+ ngendlela entsonkothileyo. Olu hlobo lwesichumisi se-iron organic lunexabiso eliphantsi kunye nefuthe elihle ekuthinteleni ukusilela kwentsimbi kunye nokulahleka okuluhlaza. Impembelelo yokulawula i-chlorosis ingcono kune-0.3% ye-ferrous sulfate.
Ukuprintwa kwe-textile kunye nokudaya
① Inokusetyenziswa njengenani elikhulu le-melamine, i-urea-formaldehyde resin, i-hydrazine hydrate, i-tetracycline, i-phenobarbital, i-caffeine, i-VAT emdaka BR, i-phthalocyanine B, i-phthalocyanine Bx, i-monosodium glutamate kunye nezinye iimveliso zokuvelisa izinto eziluhlaza.
② Inomphumela oqaqambileyo kwi-chemical polishing yensimbi kunye nensimbi engenasici, kwaye isetyenziswe njenge-corrosion inhibitor kwi-pickling yensimbi, kwaye isetyenziselwa ukulungiswa kwe-palladium activation liquid.
③ Kushishino, ikwasetyenziswa njengemathiriyeli ekrwada ukwenza urea-formaldehyde resins, polyurethanes kunye nemelamine-formaldehyde resins.
④I-ejenti ekhethiweyo yokunciphisa i-denitrification yegesi yokutshisa igesi, kunye ne-automotive urea, eyenziwe yi-32.5% ye-high-purity urea kunye ne-67.5% yamanzi adibeneyo.
⑤ Ukwahlula iparafini wax (kuba iurea inokwenza iiclathrates), imathiriyeli, iinxalenye zesibaso se-injini yokhuselo lokusingqongileyo, iinxalenye zemveliso yamazinyo amhlophe, izichumisi zekhemikhali, izinto ezincedisayo ekudayweni nasekushicileleni.
⑥ Umzi-mveliso welaphu lolona lubalaseleyo lwedayi yokunyibilikisa/i-agent yehygroscopic/i-viscose fayibha yokwandisa i-agent, i-resin finishing agent, inoluhlu olubanzi losetyenziso. Ukuthelekiswa kweempawu ze-hygroscopic ze-urea kunye nezinye i-hygroscopic agents kwi-textile industry: umlinganiselo kubunzima bayo.
Ibakala lokuthambisa (izithako zokuthambisa)
I-Dermatology isebenzisa ii-agent ezithile ezine-urea ukwandisa ukufuma kwesikhumba. Ukugqoka okuvaliweyo okusetyenziselwa izikhonkwane ezingasuswanga ngotyando kuqulethe i-40% ye-urea. I-Urea sisithako esilungileyo sokuthambisa, ikhona kwicuticle yolusu, yeyona nto iphambili yolusu yokuthambisa iNMF.
