Peb yuav ua li cas kom tsis txhob muaj teeb meem caking hauv kev ua chiv, khaws cia thiab kev thauj mus los?Qhov teeb meem caking muaj feem xyuam rau cov khoom siv chiv, av noo, kub, sab nraud siab thiab lub sijhawm cia.Peb yuav qhia luv luv txog cov teeb meem no.
Cov khoom siv feem ntau siv hauv kev tsim cov chiv yog ammonium ntsev, phosphate, kab keeb ntsev, poov tshuaj ntsev, thiab lwm yam, uas muaj crystalline dej thiab zoo li agglomerate vim noo noo nqus.Xws li phosphate yog yooj yim rau agglomerate, phosphate thiab kab kawm sib ntsib, yooj yim rau agglomerate thiab ua insoluble nyob rau hauv dej tshuaj, urea ntsib kab ntsev yog ib qho yooj yim rau precipitate tawm ntawm dej thiab agglomerate, feem ntau urea hloov cov kab keeb ntsev siv lead ua dej thiab ua. paste, thiab ces agglomerate.Fertilizer ntau lawm feem ntau tsis kaw ntau lawm, nyob rau hauv cov txheej txheem ntau lawm, huab cua noo ntau dua, cov chiv muaj feem yuav nqus dej noo thiab caking, huab cua qhuav los yog qhuav cov ntaub ntawv raw, chiv tsis yooj yim rau caking.
Qhov kub ntawm chav tsev ntau dua, qhov kev sib cais zoo dua.Feem ntau cov khoom siv raw dissolves hauv nws tus kheej cov dej crystalline thiab ua rau caking.Thaum cov nitrogen kub dua, cov dej evaporates, thiab nws nyuaj rau agglomerate, qhov kub yog feem ntau siab dua 50 degrees Celsius, thiab peb feem ntau yuav tsum tau cua sov kom tau qhov kub ntawd.
Qhov siab dua ntawm cov chiv, qhov kev sib cuag ntawm cov muaju yooj yim dua, yooj yim dua rau caking;qhov tsawg lub siab, qhov tsawg dua yuav agglomerate.
Cov chiv ntev dua yog muab tso rau, nws yooj yim dua rau caking, thiab ua kom lub sij hawm luv, qhov tsawg dua yuav ua rau caking.
