Mafotokozedwe Akatundu:
Urea, womwe umadziwikanso kuti carbamide, uli ndi formula yamankhwala CH4N2O. Ndi organic pawiri wopangidwa ndi carbon, nayitrogeni, mpweya, ndi haidrojeni. Ndi kristalo woyera.
Urea ndi feteleza wochuluka wa nayitrogeni, wosalowerera ndale, feteleza wosalowerera ndale, ndipo amathanso kugwiritsidwa ntchito popanga feteleza wamitundumitundu. Urea ndiyoyenera kuthirira feteleza wapansi ndi kuvala pamwamba, komanso nthawi zina ngati feteleza wambewu.
Monga feteleza wosalowerera ndale, urea ndi yoyenera ku dothi ndi zomera zosiyanasiyana. Ndi yosavuta kusunga, yosavuta kugwiritsa ntchito, ndipo siwononga pang'ono pa nthaka. Ndi feteleza wa nayitrogeni wa mankhwala omwe pakali pano amagwiritsidwa ntchito mochuluka. M'makampani, ammonia ndi carbon dioxide amagwiritsidwa ntchito popanga urea pansi pazifukwa zina.
Ntchito:
Ulimi ngati fetereza.
Phukusi:25 kgs / thumba kapena momwe mukufunira.
Posungira:Mankhwala ayenera kusungidwa pamthunzi ndi malo ozizira. Musalole kuti likhale padzuwa. Kuchita sikungakhudzidwe ndi chinyezi.
