Ammonium nitrate: daim ntawv thov thiab hom kev tsim khoom

Hnub no, ib qho ntawm feem ntau cov chiv yog ammonium nitrate. Nws daim ntawv thov yog ua raws li cov nyhuv qhia rau ntawm cov qoob loo. Nws siv ho ua rau kom rov qab los ntawm txhua qhov hectare ntawm agricultural av. By xa ammonium nitrate - ib tug thib ob lub npe uas yog ammonium nitrate (daim ntawv thov nws yog heev nrov hnub no) - nws nruab nrab yog muaju tsis muaj xim. Lawv muaj lub zoo hygroscopicity, yog li lawv nqus cov cua atmospheric zoo thiab dissolve sai hauv dej.

Cov cuab yeej ntawm cov khoom ntawm cov khoom siv no muaj xws li lub nruab nrab ntawm cov kua qaub los ntawm ammonia thiab tom qab evaporation ntawm kev daws. Ammonium nitrate yog granulated hauv cov khoom txawb tshwj xeeb, tom qab uas nws tau txias thiab them nrog tshuaj muaj pes tsawg leeg los ntawm kev tuav. Los ntawm ib mus rau plaub millimeters - qhov loj me me li qhov me me, nyob rau hauv daim ntawv uas tau tsim cov ammonium nitrate. Nws siv yog tsuas yog vim lub high school cov ntsiab lus ntawm nutrient nitrogen thiab qhov zoo friability ntawm fertilizer. Tom qab ntawd cov khoom ntim rau hauv cov thawv ntim ntau (cov thawv ntim, hnab) lossis xa mus rau tus neeg tau txais kev pab nyob rau hauv daim ntawv tshwj xeeb wagons.

Nyob rau hauv lub qhuav ntawm tej additives yuav tau txais ammonium nitrate, nws cov nqi nyob rau hauv rooj plaub no yuav yog nyob ntawm seb hom ntxiv muaj. Feem ntau cov feem ntau, qhov no txias neeg sawv cev muaj ib tug magnesium sulphate (tej zaum nrog phosphates), poov hlau. Thaum pom zoo nrog tus neeg tau txais kev pab, lwm cov khoom ntxiv tshiab tsis muab los ntawm cov txheej txheem technologies.

Vim yog qhov muaj zog oxidizing cov khoom uas ammonium nitrate muaj, kev siv thiab tuav ntawm cov khoom no yuav tsum tau nqa tawm nrog cov kev xyuam phaj. Hauv particular, nws tsis tuaj yeem cia rau ntev (ntau tshaj 6 lub hlis) thiab nyob rau hauv loj pawg, txij li thaum lub sij hawm caking no cov ntaub ntawv ua tseem tawg heev. Lub tsev nyob rau hauv uas nws yog khaws cia yuav tsum zoo ventilated thiab qhuav. Khaws thiab thauj ammonium nitrate cais los ntawm lwm yam tshuaj. Ntxiv rau, cov neeg uas ua hauj lwm nrog kev siv cov tshuaj no, koj yuav tsum tau ua raws li lawv tus kheej txoj kev nyab xeeb (hnav ib ce tiv thaiv, ua pa hnyuv, tsom iav).

Cov qoob loo ntau yog qhov kev lag luam tseem ceeb uas ua rau cov tshuaj ammonium nitrate. Yuav nws feem ntau xav kom cov neeg ua liaj ua teb koom nrog hauv cov av ua zaub ua mov. Nws yuav siv tau rau tag nrho cov hom ntawm cov av. Raws li txoj cai, nws yog siv raws li ib tug to top hnav khaub ncaws rau lub caij ntuj no cov qoob loo los yog raws li lub ntsiab fertilizer rau tag nrho cov hom cereals. Zoo heev ammonium nitrate cuam tshuam cov hauj lwm zoo ntawm nce lub caij nplooj ntoos hlav hom qoob mog. Nws daim ntawv qhia zoo tsis kam mus fungal kab mob thiab muaj zog stems los ntawm cereals. Tshwj xeeb tshaj yog zoo yog ib tug ua ke ntawm ammonium nitrate nrog phosphate thiab poov tshuaj chiv. On acidic xau nws yog pom zoo kom ntxiv calcareous hmoov. On teeb lub teeb, lub fertilizer yuav tsum tau siv tam sim ntawd ua ntej sowing.

Dhau li ua liaj ua teb nws yog, vim hais tias ntawm nws cov oxidizing zog, thiab yog dav siv nyob rau hauv qhov kev lag luam (rau zus tau tej cov explosives, roj).
