Uduce dusanzwe two gukurura ifumbire mvaruganda turimo uduce duto two gukurura ifumbire mvaruganda hamwe n’uduce duto two gukurura ifumbire mvaruganda. Mu gihe cyo gutunganya ifumbire mvaruganda, utu duce dushobora kongera ibintu bya azote bitewe n’ibikenewe, kandi bamwe bakoresha urea nk’isoko y’ibintu bya azote, bishobora kwinjiza ubushuhe mu kirere bigatuma uduce duto tw’ifumbire mvaruganda dufatana. Kubwibyo, bikunze kuvugwa ko uduce duto two gukurura ifumbire mvaruganda ari uduce duto two gukurura ifu yumye, dufite ingaruka nziza mu gutunganya uduce duto tw’ibikoresho fatizo bifite ubushuhe buri munsi ya 10%. Ku bikoresho bitose, hagomba gukorwa ikoranabuhanga rikenewe ryo kurwanya ubushuhe. Kugira ngo ibike uduce duto tw’ifumbire mvaruganda turimo ubushuhe nk’ibikoresho fatizo by’ifumbire mvaruganda, ni ngombwa kwirinda gukomera.
Ihame n'ibisabwa by'amazi ku ngano zitunganya ifumbire mvaruganda
Ihame ry'imikorere ya granulator yo gusohora ni ifu yumye cyane cyane nk'ibikoresho by'ibanze. Iyo ibikoresho byoroshye bipfundikiye, igice cy'uduce turashwanyaguzwa, maze ifu nziza yuzura icyuho kiri hagati y'uduce duto. Muri iki gihe, niba imigozi y'ibinyabutabire ku buso bushya idashobora kwihuta cyane hifashishijwe atome cyangwa molekile ziturutse mu kirere gikikije, ubuso bushya buhura bugakora imigozi ikomeye yo gusubiranamo. Ku bijyanye no gusohora k'umugozi, uruhu rw'umugozi rufite umuyoboro unyuranyije, usohoka mu ishusho y'umugozi, kandi uduce dusohoka mu gice cy'inyuma (impeta) tuba turi mu nkingi.Gusohora amazi bisaba ubushuhe buke. Iyo ubushuhe buri hejuru cyane, ni ngombwa kongeramo uburyo bwo kumisha mu ikoranabuhanga ryo kuyatunganya.
Umuti ku ngaruka mbi zo kwinjiza ubushuhe bw'isoko rya azote mu buryo bwo gukurura ifumbire mvaruganda
Ipfundo ry’ingufu mu ifumbire mvaruganda ahanini ni ubwinshi bw’amazi aterwa n’amazi aturuka kuri azote akuramo urea. Mu buryo bwa tekiniki, gutangira no kwihuta kw’ifumbire mvaruganda ntibiyongera iyo ammonium nitrate na potasiyumu chloride byiyongera. Urugero, uruvange rurimo ammonium nitrate 80% na potasiyumu chloride 20% ntabwo rushya, ahubwo rurimo uruvange rwa 30% by’ubutaka bwa diatomaceous, 55% ammonium nitrate, na 15% potasiyumu chloride bitanga "ubushyuhe bukabije".
Uduce tw’ifumbire mvaruganda dufite urea nk’isoko ya azote tugira ubushobozi bwo kuyungurura cyane kandi ntidushobora koroha; biuret na adducts byoroshye kubaho iyo ubushyuhe buri hejuru; urea izashiramo amazi iyo ubushyuhe buri hejuru, bigatuma amoniya ibura.
Ibi ni ngombwa kugira ngo hakemurwe ingano y'amazi menshi aterwa n'amazi akuramo azote. Kugabanya isoko ya azote Iyo kalisiyumu superphosphate ihari, fosifore ishongera mu mazi irangirika; iyo ikora ifumbire mvaruganda ya urea-common calcium superphosphate, fosifore isanzwe igomba kuvurwa mbere, nka ammoniation, ishobora gukuraho imiyoboro. Gukora, cyangwa kongeramo fosifore ya calcium magnesium kugira ngo ihagarike aside yigenga ya superphosphate, no guhindura amazi yigenga mo amazi ya kristu, kunoza ubwiza bw'umusaruro, cyangwa kongeramo ammonium sulfate, ishobora kugabanya ubushuhe bw'umusaruro urangiye no kongera ubukana bw'umusaruro urangiye; iyo hari chlorine Iyo ammonium ihinduwe, urea na chlorine bikora umuyoboro, wongera crystallization, bigatuma ifumbire yongera gushyuha byoroshye gutera ubwinshi bw'umusaruro urangiye mu gihe cyo kubika; bityo, ifumbire mvaruganda ifite urea nk'isoko ya azote igomba kwita cyane ku buryo bwo kumisha no gukonjesha.Urugero, ubushyuhe bwo kumisha ntibugomba kuba buri hejuru cyane, igihe cyo kumisha ntigikwiye kuba kirekire cyane, ubushuhe bwavuzwe mu gipimo cy’ubuziranenge bugomba kuba bwujuje ibisabwa, ikintu cyo gushonga mu gihe cyo gukora kigomba kwirindwa, kandi nta kubika imigati mu gihe cyo kubika.
Izi nizo mpamvu zituma habaho ubushuhe bwinshi mu gikorwa cyo gukurura ifumbire mvaruganda, bigatuma ipfundika. Uburyo bw'ingenzi bwo kwirinda gupfundika ni ugukoresha uburyo bwo kumisha. Gutunganya ibikoresho mbere yo kubitunganya, kongeramo ibintu n'ubundi buryo, kugira ngo habeho gutunganya no kubungabunga uduce tw'ifumbire mvaruganda tudasenya.
