Urea, izwi kandi nka urea cyangwa karbamide, ifite formulaire ya chimique CH4N2O cyangwa CO (NH2) 2. Ni uruganda kama rugizwe na karubone, azote, ogisijeni, na hydrogen, kandi ni kirisiti yera.Kimwe mu bintu byoroshe kama kama ningirakamaro nyamukuru ya azote irimo amaherezo ya protein metabolism no kubora mu nyamaswa z’inyamabere n’amafi amwe.Nifumbire idafite aho ibogamiye, urea ikwiranye nubutaka butandukanye nibimera.Biroroshye kubungabunga, byoroshye gukoresha, kandi bifite ingaruka nke zangiza kubutaka.Nifumbire mvaruganda ya azote ifite imiti myinshi ikoreshwa nibirimo azote nyinshi.Urea ikomatanyirizwa hamwe mubihe bimwe na bimwe ikoresheje ammonia na dioxyde de carbone mu nganda.
Urea irashobora gukora hamwe na acide kugirango ikore umunyu.Ifite hydrolysis.Ku bushyuhe bwinshi, reaction ya kanseri irashobora gukorwa kugirango habeho biuret, triuret, na acide cyanuric.Shyushya kugeza 160 ℃ kubora, kubyara gaze ya amoniya no kuyihindura isocyanate.Kuberako iyi ngingo iboneka mu nkari zabantu, yitwa urea.Urea irimo azote 46% (N), ikaba irimo azote nyinshi mu ifumbire ya azote ikomeye.
Urea irashobora hydrolyze kubyara ammonia na karuboni ya dioxyde de acide, base, na enzymes (acide na base bisaba gushyuha).
Kubushyuhe bwumuriro, gushyushya 150-160 ℃ bizanduza biuret.Sulfate y'umuringa ikora hamwe na biuret mu ibara ry'umuyugubwe kandi irashobora gukoreshwa mu kumenya urea.Niba ashyutswe vuba, izashyirwa mu majwi na trimeric kugirango ikore ibice bitandatu bigize cyclicique, acide cyanuric.
Acetylurea na diacetylurea birashobora kubyara mugukora hamwe na acetyl chloride cyangwa anhydride ya acetike.
Mubikorwa bya sodium etanol, ifata na diethyl malonate kugirango itange malonylurea (izwi kandi nka acide barbituric, kubera aside).
Mubikorwa bya catalizike ya alkaline nka ammonia, irashobora kwitwara hamwe na formaldehyde hanyuma igahurira muri urea formaldehyde resin.
Kora hydratine hydratine kugirango utange aminourea.

1. Niba urea ibitswe nabi, biroroshye gukuramo ubuhehere no guhunika, bigira ingaruka kumiterere yambere ya urea kandi bigatera abahinzi igihombo runaka mubukungu.Ibi bisaba abahinzi kubika urea neza.Mbere yo gukoreshwa, birakenewe ko umufuka wapakira urea.Mugihe cyo gutwara, bigomba kwitabwaho neza, bikarindwa imvura, kandi bikabikwa ahantu humye, hahumeka neza hamwe nubushyuhe buri munsi ya 20 ℃.
2. Niba ibitswe ku bwinshi, ibiti bikozwe mu biti bigomba gukoreshwa mu gusunika hasi kuri santimetero 20, kandi hagomba kubaho icyuho cya santimetero zirenga 50 hagati yo hejuru n’igisenge kugirango byoroherezwe guhumeka no gutemba.Igice kigomba gusigara hagati yumurongo.Korohereza ubugenzuzi no guhumeka.Niba urea yamaze gukingurwa idakoreshejwe, birakenewe gufunga umunwa wumufuka mugihe gikwiye kugirango byoroherezwe gukoreshwa umwaka utaha.
3. Irinde guhura n'uruhu n'amaso.
Ifumbire: 90% ya urea yakozwe ikoreshwa nkifumbire.Yongewe kubutaka kandi itanga azote kubimera.Biuret nkeya (munsi ya 0,03%) urea ikoreshwa nkifumbire y amababi.Irashobora gushonga mumazi igashyirwa kumababi yibimera, cyane cyane imbuto na citrusi.
Ifumbire ya Urea ifite ibyiza byo gutanga azote nyinshi, ifite akamaro kanini mu guhinduranya ibimera kandi bifitanye isano itaziguye n'umubare w'ibiti n'amababi bikurura urumuri rwa fotosintezeza.Byongeye kandi, azote iboneka muri vitamine na proteyine, kandi ifitanye isano na poroteyine zirimo ibinyampeke.
Urea ikoreshwa muburyo butandukanye bwibihingwa.Ifumbire irakenewe kuko ubutaka butakaza azote nyinshi nyuma yo gusarura.Urea ibice bikoreshwa mubutaka, bigomba gukora neza kandi bikungahaye kuri bagiteri.Porogaramu irashobora gukorwa mugihe cyo gutera cyangwa kare.Noneho, urea iba hydrolyzed kandi ikabora.
Ugomba kwitondera mugihe ukoresheje urea neza kubutaka.Niba ikoreshejwe hejuru, cyangwa niba itinjijwe mubutaka hakoreshejwe imikoreshereze ikwiye, imvura, cyangwa kuhira, ammonia izashira kandi igihombo ni ngombwa cyane.Kubura azote mu bimera bigaragarira mu kugabanuka kw'ibibabi no kugabanuka kw'ibikorwa bya fotosintetike.
Gufumbira kw'amababi: Gufumbira amababi ni umuco wa kera, ariko muri rusange, gukoresha intungamubiri zijyanye n'ubutaka ni bike, cyane cyane mubyinshi.Nyamara, inyandiko zimwe mpuzamahanga zerekana ko gukoresha urea urea nkeya bishobora kugabanya ifumbire ikoreshwa mubutaka bitabangamiye imikorere, ingano, nubwiza bwimbuto.Ubushakashatsi bwerekanye ko gutera amababi hamwe na ureya nkeya bigira akamaro nko gutera ubutaka.Usibye gahunda nziza yo gusama, ibi byemeza imyitozo yo gukoresha ifumbire ifatanije nindi miti yubuhinzi.
Imiti na plastiki: Urea iboneka mubifata, plastiki, resin, wino, imiti, hamwe nibikoresho byo kurangiza imyenda, impapuro, nibyuma.
Ibiryo byamatungo byiyongera: Urea ivangwa mubiryo byinka kandi itanga azote, ningirakamaro mugukora poroteyine.
Umusaruro wa resin: Urea formaldehyde resin hamwe nibindi bisiga bifite porogaramu zitandukanye mubikorwa byinganda, nko gukora pani.Zikoreshwa kandi mu kwisiga no gusiga amarangi.
Chemwin irashobora gutanga ibintu byinshi bya hydrocarbone hamwe nu muti wa chimique kubakiriya binganda.Mbere yibyo, nyamuneka soma amakuru y'ibanze akurikira yerekeye gukora ubucuruzi natwe:
1. Umutekano
Umutekano nicyo dushyira imbere.Usibye guha abakiriya amakuru ajyanye no gukoresha ibicuruzwa byacu neza kandi bitangiza ibidukikije, twiyemeje kandi ko umutekano w’abakozi n’aba rwiyemezamirimo wagabanuka kugeza ku gipimo cyiza kandi gishoboka.Kubwibyo, turasaba abakiriya kwemeza ko ibipimo bikwiye byo gupakurura no kubika ibicuruzwa byujujwe mbere yo gutanga (nyamuneka reba umugereka wa HSSE mumagambo rusange nuburyo bwo kugurisha hepfo).Impuguke zacu HSSE zirashobora gutanga ubuyobozi kuri aya mahame.
2. Uburyo bwo gutanga
Abakiriya barashobora gutumiza no gutanga ibicuruzwa biva muri chemwin, cyangwa barashobora kwakira ibicuruzwa biva muruganda rwacu rukora.Uburyo buboneka bwubwikorezi burimo amakamyo, gari ya moshi cyangwa ubwikorezi butandukanye (ibintu bitandukanye birakurikizwa).
Mugihe cyibisabwa abakiriya, turashobora kwerekana ibisabwa bya barge cyangwa tanker hanyuma tugashyiraho umutekano wihariye / gusuzuma ibipimo nibisabwa.
3. Umubare ntarengwa wateganijwe
Niba uguze ibicuruzwa kurubuga rwacu, umubare ntarengwa wateganijwe ni toni 30.
4. Kwishura
Uburyo busanzwe bwo kwishyura ni kugabanywa bitarenze iminsi 30 uhereye kuri fagitire.
5. Inyandiko zitangwa
Inyandiko zikurikira zitangwa na buri gutangwa:
· Umushinga w'itegeko, CMR Waybill cyangwa izindi nyandiko zijyanye no gutwara abantu
· Icyemezo cyo gusesengura cyangwa guhuza (niba bikenewe)
· Inyandiko zijyanye na HSSE zijyanye n'amabwiriza
· Inyandiko za gasutamo zijyanye n'amabwiriza (niba bikenewe)
