Ntsev ugleammoniynye: hauj lwm, muaj pes tsawg leeg, uas

Zoo tsis muaj ntau lawm kev lag luam ua tsis tau yam uas tsis muaj sib active tshuaj. Additives siv nyob rau hauv ua liaj ua teb, khoom noj khoom haus kev lag luam, thaum lub sij hawm tanning, nyob rau hauv kev tsim kho thiab nyob rau hauv ntau lwm spheres ntawm tib neeg kev ua si. Ntawm tag nrho ntawm lawv nyob ib tug tshwj xeeb qhov chaw ugleammoniynye ntsev, uas yog universal.

Ugleammoniynaya ntsev

Ugleammoniynaya ntsev - inorganic compound yog dawb, nkag soluble nyob rau hauv dej, yog cov tshuaj tiv thaiv cov khoom ntawm carbonic acid thiab ammonium ntsev.

Muaju tshuaj nraum zoov decompose sai heev tso loj nyiaj ntawm ammonia thiab carbon dioxide, thiab ces qhuav. Muaj ob hom tshuaj tebchaw:

1. Ntsev ugleammoniynye hom B, uas muaj kev koom siv nyob rau hauv lub steel kev lag luam thaum lub sij hawm tsuas ntawm uranium ore mus rau lub flotation txheej txheem, cov neutralization ntawm chrome tawv thiab coloring khoom.
2. Ntsev ntawm hom A, uas yog siv rau cov organic khoom, synthesizing tshuaj.

Tag nrho cov hom ntawm cov tshuaj tebchaw yog tsis soluble nyob rau hauv ethanol thiab acetone. Npaj tshuaj pib ntawm redox tshua ntawm ammonium ntsev thiab carbonic acid.

tshuaj nyob tus yeees

Nyob rau hauv raws li tsoom fwv cov qauv, ntsev ugleammoniynye yuav tsum tau raws li nyob rau hauv lub qhuav rau lub substance ntawm tsawg kawg 99% ammonium bicarbonate, ammonium carbonate - tsis muaj ntau tshaj li 1%, thiab khi dej rau hauv molecular theem yog tsis ntau tshaj li 3%.

Lub caij nyoog tshuaj nyob tus yeees ntawm cov nuj nqis tej zaum yuav txawv nyob ntawm seb daim ntawv thov crystal-substance. Yog li, rau cov zaub mov kev lag luam nyob rau hauv muaj pes tsawg leeg yuav tsum muaj tsawg kawg yog 20,9% NH _3. Pawg feem ntawm lwm yam tebchaw yog nruj me ntsis tswj lub moj khaum thiab yuav tsum tsis txhob ntau tshaj li nram qab no qhia:

• hnyav hlau - 5 * 10 ^-4;
• Arsenic - 1 x 10 ^-4;
• valent hlau thiab nws cov tebchaw - 1 * 10 ^-3;
• tshuaj thiab chlorides - 1 * 10 ^-3;
• dej insoluble tebchaw - 5 * 10 ^-3.

Cov ntsuas txhais TU U 6-04687873.025-95 tshuaj mis - NH ₄ HCO _3.

Lub cev thiab tshuaj tsis

Ugleammoniynye ntsev muaj tsis uas txiav txim yuav ua li cas lawv kev tshuaj:

• Hawj txawm siv lead ua cov ntaub ntawv uas muaj peev xwm yuav sawv cev los ntawm dawb, liab, los yog txho zas;
• qhov loj feem ntawm ammonia rau cov pab pawg A yuav tsum tau raws li 21% rau B qib - 20.7%;
• loj tshuav nyiaj li cas tom qab calcination yuav tsum tsis ntau tshaj li 0,008% rau hom A, thiab tsis ntau tshaj 0,02 rau lub hom B.

Tsuas yog ib yam khoom uas coj mus rau cov tsis yuav tau txhais raws li ugleammoniynaya ntsev. GOST 9325-79 tsim cov kev cai, raws li tau zoo raws li regulates cov kev cai ntawm qhuav, thauj thiab cia, ceev faj thiab kev nyab xeeb.

Scope

Cov feem ntau lug ugleammoniynaya ntsev tau nyob rau hauv cov zaub mov kev lag luam thiab ua liaj ua teb. Nyob rau hauv thawj cheeb tsam nws yog thov nyob rau hauv lub guise E503 additives feem ntau xyoo cov khoom noj khoom haus poov xab thiab ammonium carbonate zaub mov. Yog xav thov cov tshuaj yeeb dej caw yog yaj nyob rau hauv dej nyob rau hauv 20 ^{° C} thiab saum toj no, thiab ces ntxiv rau cov mis sib tov ua ntej nag lossis daus hmoov.

Lub cev thiab tshuaj tsis ugleammoniynoy ntsev pub nws siv li ib tug fertilizer. Plaug tshuaj muaju tau slowing los yog tiav siv ceev xwmphem cov txheej txheem ntawm tsub zuj zuj ntawm nitrites nyob rau hauv cov av, uas beneficially cuam tshuam rau tus nqi ntawm cov qoob loo maturation, thiab:

1. Loo nce los ntawm 15-45%.
2. Cov thawj zaug rau theem ntawm fruiting cov qoob loo coj tom ntej los ntawm ib lub lim tiam los yog ob tug.
3. Nws thiaj li qhov yuav tsum tau rau cov av phosphorus chiv.
4. Nws yeej txhawb lub tsim ntawm humus.

Nyob rau hauv peb lub teb chaws, zus tau tej cov chiv rau hauv lub hauv paus ugleammoniynoy ntsev yog teem rau lub domestic ua lag luam, vim li cas tus nqi ntawm cov khoom yog qis tshaj tus nqi ntawm txawv teb chaws analogues.

precautionary ntsuas

Ugleammoniynye ntsev xa mus rau lub 4 chav kawm ntawv ntawm kev txaus ntshai. Nyob rau hauv lawv cov qauv muaj ob tej rau tib neeg noj qab haus huv - ammonia thiab carbon dioxide. Tus thawj lub caij no mas lom thaum nqus tau cov pa ua rau voos. Yog hais tias lom muaj feem xyuam rau lub hauv paus poob siab system, muaj yog ib tug mob taub hau, qhov muag los kua, tu-sauv thiab lwm yam kev mob.

Carbon dioxide muaj ib tug narcotic thiab soporific nyhuv. Nyob rau hauv loj qhov ntau destabilizing lub ntsws chaw, ua txhaws qa thiab yuav ua rau txoj kev tuag los ntawm tsis muaj oxygen.

Yog li ntawd, siv ntawm ntsev ugleammoniynye tau tsuas yog nyob rau hauv tshwj xeeb khaub ncaws, tsom iav qhov muag, hnab looj tes, resistant rau alkalis, qhov ncauj qhov ntswg. Tom qab ua hauj lwm cov kev cai ntawm tus kheej kev tu cev, zoo tshaj plaws sov da dej.
