Ammonium Bicarbonate (tseem hu ua Ammonium Carbonate, Acidic Ammonium Carbonate, abbreviated as ABC) yog ntau yam thiab raug nqi -cov khoom siv tshuaj inorganic zoo. Nws yog tsim nyob rau hauv peb qib loj - qib zaub mov, qib industrial, thiab qib kev ua liaj ua teb- thiab yog siv dav hauv kev ua zaub mov, tshuaj synthesis, kev cog qoob loo, thiab kev kho dej ib puag ncig.
I. Cov ntawv thov hauv Kev Lag Luam Kev Lag Luam (yav tas los siv ntau tshaj plaws)
1. Siv ua chiv nitrogen (ammonium nitrogen)
Muab nitrogen los txhawb kev loj hlob ntawm cov hauv paus hniav, stems, thiab nplooj.
Cov qoob loo siv tau: nplej, pob kws, nplej, zaub, thiab lwm yam.
Daim ntawv thov txheej txheem: basal daim ntawv thov, topdressing, daim ntawv thov trench, daim ntawv thov qhov.
Qhov zoo:
Tus nqi qis
Kev tso tawm sai sai
Tsawg acidification (piv nrog urea)
Kev txwv (ua rau txo qis kev thov):
Ceev ammonia volatilization (tsawg nitrogen-siv efficiency)
Nyuaj rau decompose thaum khaws cia thiab thauj
Tsis ua raws li cov kev cai ntawm kev ua liaj ua teb niaj hnub
Lub teb chaws txoj cai tab tom ua haujlwm qis - cov chiv ua tau zoo
Kev lag luam xwm txheej:
Kev siv ammonium bicarbonate raws li chiv txuas ntxiv zuj zus txhua xyoo, hloov los ntawm urea, ammonium nitrate, thiab lwm yam.
II. Cov ntawv thov hauv Kev Lag Luam Khoom Noj (kev loj hlob ruaj khov)
Ammonium bicarbonate yog dav siv los ua zaub mov additive E503(i).
1. Feem ntau yog siv los ua ib tug leavening neeg sawv cev
Nws decomposes raws li cua sov los tsim CO₂ + NH₃ + H₂O, muab cov khoom nthuav thiab crispness.
Yam khoom noj uas siv tau:
Biscuits, dej qab zib crackers
Cov ncuav pastries (xws li, Taosu, Xav Xav Mini buns)
Extruded khoom noj txom ncauj, paj kws
Cov zaub mov kib (hauv qee thaj tsam)
Daim ntawv thov nta:
Tsis tsim cov alkaline saj (tsis zoo li sodium bicarbonate)
Muaj zog leavening nyhuv thiab muaj peev xwm los tsim "hollow structures"
Haum rau cov khoom noj qhuav, nyias, lossis nkig
Kev lag luam yam ntxwv:
Cov zaub mov- qib kev ua lag luam yog me me tab sis ruaj khov, nrog cov kev xav tau zoo thiab muaj txiaj ntsig ntau dua piv nrog cov chiv thiab qib kev lag luam.
III. Daim ntawv thov hauv Kev Lag Luam Tshuaj (ntau lub luag haujlwm)
1. Raw khoom rau tshuaj synthesis
Siv nyob rau hauv kev tsim khoom ntawm:
Lwm cov ntsev ammonium (xws li ammonium carbonate, ammonium nitrate)
Catalyst cab kuj
Dyes thiab auxiliaries
2. pH regulator nyob rau hauv cov txheej txheem tshuaj
Muab me ntsis alkalinity tom qab decomposition.
3. Hlau ua thiab tu
Siv los ua tus neeg sawv cev buffering hauv cov txheej txheem kho mob hlau.
IV. Daim ntawv thov hauv Rubber thiab Plastics Industries (tus neeg saib xyuas tshuab tshuab)
Hauv kev tsim cov ntaub ntawv foamed (piv txwv li, khau khau, cushioning cov ntaub ntawv):
1. Ua raws li qhov qis-kub auxiliary tshuab tshuab
Siv ua ke nrog AC tshuab tshuab (azodicarbonamide), pab txo qis foaming kub thiab txhim kho cell uniformity.
Nta:
Tsawg decomposition kub, cia ua ntej tso pa tawm
Txhim kho cov qauv ua npuas ncauj
Cov khoom siv tseem ceeb:
EVA ua npuas ncauj khoom (slippers, khau khau)
PE / PP ua npuas ncauj
Roj hmab gaskets thiab cushioning Cheebtsam
V. Daim ntawv thov hauv Kev Tiv Thaiv Ib puag ncig (niche tab sis loj hlob)
1. Flue gas denitrification (kev txhawb nqa rau SNCR/SCR)
Decomposition tso NH₃, ua ib qho chaw ammonia rau denitrification systems.
Qhov zoo:
Kev ruaj ntseg cia piv nrog cov kua ammonia lossis dej ammonia
Tsis tau muab cais ua ib qho tshuaj lom neeg
2. Kev kho dej khib nyiab
Siv los ua ib qho me me alkaline lossis ammonium qhov chaw los kho pH thiab txhawb kev tiv thaiv nag lossis daus.
VI. Kev siv tshuaj thiab kev kuaj mob
1. Pharmaceutical excipient
Siv nyob rau hauv tej formulations rau foaming, loosening, los yog raws li ib tug intermediate.
2. Laboratory reagent
Siv nyob rau hauv analytical chemistry, ion pauv, thiab qauv pretreatment.
Daim ntawv thov Trend Summary
1. Kev siv chiv tseem pheej poob qis
Tsav los ntawm kev txwv txoj cai thiab kev txhawj xeeb txog kev ua haujlwm.
2. Kev siv khoom noj thiab tshuaj lom neeg nyob ruaj khov
Khoom noj khoom haus- qib kev siv me me tab sis qhia tau hais tias kev loj hlob ntawm cov kab.
3. Cov ntaub ntawv ua npuas ncauj thiab daim ntaub ntawv tiv thaiv ib puag ncig tau nce me ntsis
Tsav kev lag luam mus rau kev lag luam tshwj xeeb - cov ntawv thov qib.
4. Kev lag luam hloov mus rau siab -purity thiab stabilized khoom:
* Anti-caking ammonium bicarbonate
* Tsawg- noo noo, qis- qib impurity
* Ntxiv qhov tseem ceeb ntawm zaub mov-qib thiab kws tshuaj- ntawv pov thawj qib
