Ib txoj kev zoo rau kev npaj ammonium polyphosphate sulfate suspensions, uas raug tshem tawm yog tsim nyog siv rau hauv cov huab cua txias, uas txheej txheem muaj yeej tseem ceeb ntawm ib txhij khoom.
Ntawm qhov kub thiab txias ntawm kwv yees li 50 ° F txog 200 ° F., muaj dej ntawm anhydrous ammonia rau cov yeeb nkab-khaub lig-tsho ntawm cov yeeb nkab-hla, feem ntau tag nrho entalpy ntxiv rau nws tshaj thiab saum toj kawg nkaus uas tau muab los ntawm kev kub nyhiab ib puag ncig ntawm kev txav ntawm kev txauv txhais tau tias kev sib txuas lus nrog rau ib kab hais yav tom ntej hais txog cov kua fertilizer reactor; ib txhij khoom, ntawm qhov kub siab li ntawm 50 ° F mus txog 200 ° F., ib tug kwj ntawm cov phomphoric acid ntawm tus tub lag luam phosphoric acid rau seem ntawm cov yeeb nkab-hla dej, hais tias phosphoric acid muaj P 2 O 5 cov ntsiab lus qhov ntawm thaj tsam li ntawm 50 feem pua mus txog 58 feem pua, feem ntau tag nrho cov entalpy ntxiv rau qhov tshaj thiab saum toj kawg nkaus uas tau txais los ntawm qhov chaw sov kub kub nkag los ntawm tshav kub pauv txhais tau tias kev sib txuas lus nrog ib lub suab qis dua kua tshuaj tom qab txhais tau tias; ua ke ib ntus, ntawm qhov kub li ntawm 50 ° F mus txog 100 ° F., ib tug kwj ntawm sulfuric acid rau hais tias qhov cross section ntawm cov yeeb nkab-cross reactor, said sulfuric acid uas muaj li ntawm 90 txog 130 feem pua ntawm qhov hnyav H 2 SO 4 , said ntws ntawm phosphoric acid thiab sulfuric acid hu tau hais tias anhydrous ammonia qhia tau hais tias feem ntau cov yeeb nkab ntawm kev hais tias cov yeeb nkab-cov yeeb hla ntawm kev tshuam ntawm qhov hais tias cov yeeb nkab-hla reactor ntawm qhov kub txaus kom txaus kom ntxiv dej tsis tsim nyog rau kev khiav hauj lwm nrawm thiab nyob rau hauv ntau qhov sib npaug ntawm ib leeg rau ib leeg rau hauv cov txiaj ntsig ntawm cov khoom tiav ammonium polyphosphate sulfate tsim nyob rau hauv ib kauj ruam tom qab-hais ib qho N: P 2 O 5 piv rau ntawm 0.35 txog 0.39; tom qab qhia txog cov tshuaj tiv thaiv los ntawm kev hu rau anhydrous ammonia, phosphoric acid, thiab sulfuric acid mus rau hauv ib lub raj txuas ntxiv ntawm cov yeeb nkab-cross reactor kom paub tseeb tias kev sib cuag ntawm kev sib txuas ntawm kev sib txuas; tom qab kev tso tawm los ntawm qhov nqes kawg ntawm kev hais tias vaporization tubular ncua qhov tseem ceeb anhydrous molten ammonium polyphosphate sulfate thiab qhia tau hais tias tawm ntawm tsev pheebsuab sulfate ua kua dej ua kua reactor txhais tau tias; ib txhij nrog said hais txog kev sulfate, qhia rau hauv said kua chiv reactor txhais tau hais tias ib tug kwj ntawm aqueous medium nyob rau hauv qhov ntau mus muab dej ntawm formulation thereto txaus rau cov tsim ntawm kua chiv nominally ntawm qib 12-30-0- (2-8) S; tom qab ntxiv ntxiv rau said nominal qib ntawm 12-30-0- (2-8) S txog 11/2 feem pua los ntawm hnyav gelling clay; intimately mixing said av nplaum nrog hais tias kua chiv thiab ua rau cov tsim muaj cov kua qoob loo ntawm cov khoom ua kua; said tias ua tau kua chiv raug rho tawm qhov khoom ntawm qhov tseeb tias qhov sib zog ntawm qhov khoom kub ntawd yog li -25 ° F.
Raws li ib tug tshiab muaj pes tsawg leeg ntawm ib qho ammonium polyphosphate sulfate paus kua los yog raug ncua cov chiv muaj txij li 10 txog 60 feem pua ntawm cov P 2 O 5 qhov nqis uas nyob rau hauv daim ntawv ntawm polyphosphate tsiaj, muaj cov phlu ntsiab lus ntawm li 3 txog li 8 feem pua, muaj N: P 2 O 5 phaus piv ntawm li 0.38 txog li 0.39, thiab muaj qhov kub kom txias ntawm -25 ° F.
