U-Urea, owaziwa nangokuthi u-Urea noma i-Carbamide, unefomula yamakhemikhali Ch4N2O noma i-CO (NH2) 2. Kuyinto ehlanganisiwe ye-organ. Enye yezinhlanganisela ezilula ze-organic ngumkhiqizo ophambili we-nitrogen oqukethe ama-protein metabolism kanye nokubola kwezilwane ezincelisayo kanye nezinhlanzi ezithile. Njengomanyolo ongathathi hlangothi, urea ulungele inhlabathi ehlukahlukene nezitshalo. Kulula ukulondolozwa, elula ukuyisebenzisa, futhi inomphumela omncane obhubhisayo emhlabathini. Kungumanyolo wamakhemikhali we-nitrogen ngenani elikhulu lokusetshenziswa kanye nokuqukethwe okuphezulu kakhulu kwe-nitrogen. U-Urea uguqulwa ngaphansi kwezimo ezithile usebenzisa i-ammonia nekhabhoni diokdide embonini.
U-Urea angaphendula ngama-acid ukuze akhe usawoti. Ine-hydrolysis. Emazingeni okushisa aphezulu, ukusabela kwamandla kungenziwa ukukhiqiza i-biuret, trieret, ne-cyanuric acid. Ukushisa ku-160 ℃ ukubola, kukhiqize igesi ye-ammonia futhi ukuguqula kube yi-isocyanate. Ngoba le nto ikhona emchameni wabantu, ibizwa ngokuthi urea. I-Urea iqukethe ama-46% nitrogen (n), okungukuthi okuqukethwe okuphezulu kakhulu kwe-nitrogen phakathi komanyolo oqinile we-nitrogen.
I-Urea ingakwazi ukukhiqiza i-ammonia nekhabhoni i-dioxide ngaphansi kwesenzo sama-acid, izisekelo, nama-enzymes (ama-acid nezisekelo zidinga ukufudumeza).
Ukuze kungazinzile okushisayo, ukufudumeza kuya ku-150-160 ℃ kuzokwanda ku-biuret. I-Copper Sulfate isabela nge-biuret ngombala onsomi futhi ingasetshenziselwa ukukhomba u-Urea. Uma kufuthelwa ngokushesha, kuzobe kubangelwa ama-deamanmonised kanye nosizi ukwakha i-cyclic ye-cyclic eyilungu lesithupha, i-cyanuric acid.
I-acetylurea kanye ne-diacetylurea kungenziwa nge-acytyl chloride noma i-acetic anhydride.
Ngaphansi kwesenzo se-sodiumthan ethanol, iphendula nge-diethyl malonate ukukhiqiza i-malowerlure (eyaziwa nangokuthi i-barbitic acid, ngenxa ye-acidity yayo).
Ngaphansi kwesenzo se-Alkaline Catalysts efana ne-ammonia, kungasabela nge-formaldehyde futhi kususwe e-Urea ForkdehydeDehyde Resin.
Baphendule nge-hydrazine hydrate ukukhiqiza i-Aminourea.

1. Uma u-urea ugcinwa ngokungafanele, kulula ukumunca umswakama kanye nesiqu, okuthinta ikhwalithi yasekuqaleni ye-urea futhi kubangele ukulahleka okuthile komnotho kwabalimi. Lokhu kudinga abalimi ukugcina kahle urea. Ngaphambi kokusebenzisa, kuyadingeka ukugcina isikhwama sokupakisha urea siqinile. Ngesikhathi sokuhamba, kufanele kusingathwe ngokunakekela, ivikelwe emvuleni, futhi igcinwe endaweni eyomile, enomoya omuhle ngokushisa ngaphansi kwama-20 ℃.
2. Uma igcinwe ngamanani amakhulu, amabhlogo okhuni kufanele asetshenziselwe ukucwazimula ezansi cishe amasentimitha angama-20, futhi kufanele kube negebe lamasentimitha angaphezu kwangu-50 phakathi kwe-top kanye nophahla lokuqalisa umoya kanye nomswakama. Indima kufanele ishiywe phakathi kwezitaki. Ukwenza lula ukuhlolwa nomoya omncane. Uma i-Urea esele ivuliwe ayisetshenziswanga, kuyadingeka ukusayina ngomlomo wesikhwama ngesikhathi esifanele ukwenza lula ukusetshenziswa ngonyaka olandelayo.
3. Gwema ukuxhumana nesikhumba namehlo.
Umanyolo: 90% ye-Urea ekhiqizwayo isetshenziswa njengomanyolo. Ingezwe enhlabathini futhi ihlinzeka nge-nitrogen yezitshalo. I-biuret ephansi (ngaphansi kuka-0.03%) urea usetshenziswa njengomanyolo wefoliya. Kuyancibilika emanzini futhi isetshenziswa emaqabungeni ezitshalo, ikakhulukazi izithelo kanye ne-citrus.
Umanyolo we-Urea unethuba lokuhlinzeka ngokuqukethwe okuphezulu kwe-nitrogen, okubaluleke kakhulu nge-metabolism yezitshalo futhi kuhlobene ngqo nenombolo yeziqu namaqabunga amunca ukukhanya kwe-photosynthesis. Ngaphezu kwalokho, i-nitrogen ikhona kumavithamini nakumaprotheni, futhi ihlobene nokuqukethwe kwamaprotheni.
I-Urea isetshenziswa ezinhlotsheni ezahlukahlukene zezilimo. Ukuvundiswa kuyadingeka ngoba inhlabathi ilahlekelwa yi-nitrogen eningi ngemuva kokuvunwa. Izinhlayiya ze-Urea zisetshenziswa emhlabathini, okufanele zisebenze kahle futhi zicebe kuma-bacteria. Uhlelo lokusebenza lungenziwa ngesikhathi sokutshala noma ngaphambili. Ngemuva kwalokho, u-Urea unama-hydrolyzed futhi ubolile.
Kufanele kuthathwe ukunakekelwa lapho ufaka i-urea kahle enhlabathini. Uma isetshenziswa ebusweni, noma ingafakwa emhlabathini ngokusetshenziswa okufanele, imvula, noma ukunisela, i-ammonia izoshintsha futhi ukulahleka kubaluleke kakhulu. Ukuntuleka kwe-nitrogen ezitshalweni kuboniswa ekwehleni kweqabunga kanye nokwehla komsebenzi we-photosynthetic.
Ukuvundiswa kweqabunga: Ukuvundiswa kweqabunga kuwumkhuba wakudala, kepha ngokuvamile ukukhuluma, ukusetshenziswa kwezakhi zomhlabathi ezihlobene nenhlabathi kuncane, ikakhulukazi ngokuya ngamanani amakhulu. Kodwa-ke, amanye amarekhodi aphesheya akhombisa ukuthi ukusetshenziswa kwe-urea ye-urea ephansi kunganciphisa inani lomanyolo osetshenziswa enhlabathini ngaphandle kokuyekethisa ukusebenza, usayizi, nekhwalithi yezithelo. Ucwaningo selukhombisile ukuthi ukufafaza ngemali elinenani elincane le-urea kuyasebenza njengokufafaza kwenhlabathi. Ngaphezu kwezinhlelo ezisebenzayo zomanyolo, lokhu kuqinisekisa umkhuba wokusebenzisa umanyolo ngokuhlangana namanye amakhemikhali ezolimo.
Amakhemikhali namapulasitiki: U-Urea ukhona ezinamathelayo, amapulasitiki, ama-resins, ama-inks, amakhamishini, kanye nama-ejenti wokuqeda izindwangu, iphepha nezinsimbi.
Isengezo sokudla seLivestock: Urea uxutshwe nokuphakelwa kwenkomo futhi uhlinzeka nge-nitrogen, ebaluleke kakhulu ekwakhekeni kwamaprotheni.
I-Resin Production: I-Urea Forkdehyde Resin namanye ama-resins banezicelo ezahlukahlukene embonini, njengokukhiqizwa kwe-plywood. Zisetshenziswa nezimonyo kanye nopende.
IChemWin inganikeza uhla olubanzi lwezinqwaba ze-hydrocarbons nama-solvents amakhemikhali amakhasimende wezimboni.Ngaphambi kwalapho, sicela ufunde imininingwane elandelayo eyisisekelo ngokwenza ibhizinisi nathi:
1. Ezokuphepha
Ukuphepha kuyinto eza kuqala kithi. Ngaphezu kokuhlinzeka amakhasimende ngolwazi mayelana nokusetshenziswa okuphephile nakwezemvelo kwemikhiqizo yethu, futhi sizibophezele ekuqinisekiseni ukuthi izingozi zokuphepha zabasebenzi nosonkontileka zincishiswa ubuncane obunengqondo nezenzeka. Ngakho-ke, sidinga ikhasimende ukuthi liqinisekise ukuthi amazinga afanele okulayisha kanye namazinga okuphepha okugcina ahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke kwi-HSSE Isithasiselo ngemigomo nemibandela yokuthengisa engezansi). Ochwepheshe bethu be-HSSE banganikeza ukuholwa kulezi zindinganiso.
2. Indlela Yokulethwa
Amakhasimende angakwazi uku-oda futhi alethe imikhiqizo kusuka ku-Cheminjin, noma angathola imikhiqizo kwisitshalo sethu sokukhiqiza. Izindlela ezitholakalayo zokuhamba zifaka iloli, isitimela noma ezokuhamba ze-multimodal (izimo ezihlukile ziyasebenza).
Endabeni yezidingo zamakhasimende, singacacisa izidingo zamabhande noma amathangi futhi sisebenzise amazinga okuphepha akhethekile / wokubuyekezwa nezidingo.
3. Ubuncane be-oda
Uma uthenga imikhiqizo kwiwebhusayithi yethu, inani eliphansi le-oda lingamathani angama-30.
4.Fay
Indlela yokukhokha ejwayelekile ukuncishiswa okuqondile kungakapheli izinsuku ezingama-30 ku-invoice.
5. Imibhalo Yokulethwa
Imibhalo elandelayo ihlinzekwa ngokulethwa ngakunye:
· I-Bill of Lading, CMR Waybill noma enye incwadi efanele yokuhamba
· Isitifiketi sokuhlaziywa noma ukuhambisana (uma kudingeka)
Imibhalo ehlobene ne-HSSE ngokuhambisana nemigomo
· Imibhalo yamasiko ehambisana nemigomo (uma kudingeka)
