Methylene Urea (MU) yog tsim los ntawm urea thiab formaldehyde nyob rau qee qhov xwm txheej. Yog tias siv urea ntau dua thaum muaj tshuaj tiv thaiv urea thiab formaldehyde, cov saw luv urea formaldehyde qeeb tso chiv yuav tsim tawm.

Nyob ntawm qhov sib txawv ntawm cov kua nitrogen hauv dej, nitrogen tuaj yeem muab faib ua dej soluble nitrogen (WN), dej tsis yaj nitrogen (WIN), dej kub yaj nitrogen (HWN), thiab dej kub tsis haum nitrogen (HWIN). Dej txhais tau tias 25 ± 2 ℃ dej, thiab dej kub txhais tau tias yog 100 ± 2 ℃ dej. Kev tso tawm qeeb qeeb tau qhia los ntawm tus lej ntsuas ua haujlwm (AI). AI = (Yeej-HWIN)/Yeej*100%. Cov txiaj ntsig AI sib txawv txiav txim siab qib qis ntawm methylene urea nitrogen. Cov saw hlau luv yog qhov yooj yim dua thiab daws tau yooj yim los ntawm cov kab mob me me hauv av, raws li cov saw ntev dua yog cov dej tsis haum thiab xav tau sijhawm ntxiv los daws cov kab mob me.

Peb cov txheej txheem tsim khoom MU lees paub peb tsim cov thev naus laus zis uas tau lees paub, uas muaj cov txheej txheem yooj yim thiab cov yam ntxwv ntawm kev tswj tau yooj yim. Peb tuaj yeem tsim cov hmoov me me thiab hmoov MU, uas muaj dej txias tsis txaus nitrogen ntau ntawm 20% mus rau 27.5%, kev ua haujlwm ntsuas ntau ntawm 40% txog 65% thiab tag nrho cov nitrogen ntau ntawm 38% txog 40%.

 Cov txheej txheem tshuaj tiv thaiv siv cov yam ntxwv ntawm urea cov cua sov ntawm kev daws thiab tso tawm cua sov hauv cov txheej txheem tshuaj tiv thaiv kom txaus, uas siv lub zog qis. Cov khoom tsim tawm muaj qhov ua tau zoo thiab muaj plua plav me me.

MU hauv cov ntawv me muaj qhov loj me ntawm 1.0mm txog 3.0mm, thiab hmoov sib txawv ntawm 20 mesh mus rau 150 mesh.

MU yog qhov tseem ceeb qeeb tso nitrogen cov peev txheej. Nitrogen peev txheej ntawm MU tso tawm thiab ua rau qeeb qeeb hauv kev ua dej thiab kab mob me me hauv av. Purified MU yog dawb thiab tuaj yeem ua rau hauv cov hmoov lossis cov hmoov. Feem ntau ntawm lawv tau siv los sib xyaw lossis sib xyaw rau hauv N, NP, NK lossis NPK chiv. Kev ua tau zoo dua yog mus txog thaum MU tau sib xyaw nrog lwm qhov chaw nitrogen daws. Los ntawm kev sib xyaw ntau qhov sib txawv lossis qhov sib piv ntawm MU, kev tshuaj xyuas NPK sib txawv thiab feem pua ​​ntawm Kev Tso Tawm Qub Nitrogen tuaj yeem ncav cuag.

Tau txais txiaj ntsig

Nitrogen hauv MU tuaj yeem tso tawm qeeb, uas zam kev hlawv tsob ntoo hauv paus lossis nplooj, loj hlob ntawm cov nroj tsuag, thiab ntws tawm ntawm cov chiv. MU muaj qhov ruaj khov thiab nyab xeeb tso cov nitrogen qis, uas ua tau raws li ntau daim ntawv thov, suav nrog kev cog qoob loo, cog qoob loo loj, txiv hmab txiv ntoo, paj, nyom thiab lwm yam nroj tsuag. Yog li ntawd, peb MU tau siv ntau dua thiab ntseeg tau.

l Txo qhov poob ntawm nitrogen rau cov nroj tsuag

l Ua kom muaj txiaj ntsig zoo dua qub

l Ntev ntev tshaj tawm nitrogen

l Txo tus nqi ntawm kev ua haujlwm

l Txo kev pheej hmoo ntawm kev hlawv tsob ntoo

l High uniformity rau blending
