Chaw tsim tshuaj paus Zoo Nqe Ammonium Chloride CAS: 12125-02-9

Ammonium chloride, (qeb kev lag luam) Ammonium chloride (hu ua "chloramine", tseem hu ua halogen xuab zeb, tshuaj formula: NH4Cl) yog xim tsis muaj xim cubic siv lead ua lossis dawb crystalline hmoov.Nws saj qab ntsev thiab iab me ntsis thiab belongs rau acid ntsev.Nws tus txheeb ze ntom ntom yog 1.527.Nws yog soluble hauv dej, ethanol thiab kua ammonia tab sis insoluble hauv acetone thiab ether.Cov tshuaj aqueous yog qaug zog acidic, thiab nws cov acidity yog txhim kho thaum cua sov.Thaum rhuab mus rau 100 ° C, nws pib volatilize, thiab thaum rhuab mus rau 337.8 ° C, nws yuav dissociate mus rau hauv ammonia thiab hydrogen chloride, uas, nyob rau hauv txias raug, yuav rov ua ke los tsim me me hais ammonium chloride thiab cov pa luam yeeb dawb. uas tsis yooj yim rau tog thiab nyuaj heev kom yaj hauv dej.Thaum rhuab mus rau 350 ° C, nws yuav sublimate thiab thaum 520 ° C, nws yuav boil.Nws qhov nqus dej yog me me, thiab nyob rau hauv cov huab cua ntub dej tuaj yeem nqus dej noo rau lub ncuav mog qab zib.Rau cov ferrous hlau thiab lwm yam hlau, nws yog corrosive, uas, tshwj xeeb tshaj yog, muaj ntau dua corrosion ntawm tooj liab tab sis tsis muaj corrosion ntawm npua hlau.Ammonium chloride tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv tsis zoo ntawm ammonia thiab hydrogen chloride lossis ammonia thiab hydrochloric acid (kev sib npaug sib npaug: NH3 + HCl → NH4Cl).Thaum rhuab, nws yuav decompose rau hauv hydrogen chloride thiab ammonia cov tshuaj tiv thaiv (kev sib npaug: NH4Cl → NH3 + HCl) thiab cov tshuaj tiv thaiv tsuas yog rau sab xis yog tias lub thawv qhib.
Ammonium chloride feem ntau yog siv rau cov roj teeb qhuav, cov roj teeb cia, ammonium ntsev, tanning, plating, tshuaj, yees duab, electrodes, adhesives, thiab lwm yam.Nws yog physiological acidic fertilizer thiab haum rau hom qoob mog, nplej, pob kws, rapeseed thiab lwm yam qoob loo.Nws muaj cov teebmeem ntawm kev txhim kho fiber ntau toughness thiab nro thiab txhim kho zoo tshwj xeeb tshaj yog rau paj rwb thiab linen qoob loo.Txawm li cas los xij, vim qhov xwm txheej ntawm ammonium chloride, yog tias daim ntawv thov tsis raug, nws yuav ua rau muaj kev cuam tshuam tsis zoo rau cov av thiab cov qoob loo.
Cov xwm txheej txheej txheem: kev ua raws li cov neeg koom pheej ntawm Tuam Tshoj lub teb chaws tus qauv GB-2946-82.

Ammonium chloride yog siv los ua cov thickener thiab ua ib qho ntxiv hauv cov tshuaj tsis muaj cawv.Raws li cov tshuaj pleev ib ce, cov tshuaj ammonium muab cov tingling lossis stinging hnov ​​​​qab uas qee cov neeg koom nrog toners lossis aftershaves, thiab uas, hauv cov toners tsis tu ncua, feem ntau yog muab los ntawm cov ntsiab lus cawv.Kev siv ammonium chloride yog qhov tshwm sim ntawm kev nyiam hauv kev xav.
Ammonium Chloride yog lub khob noom cookie txias thiab cov khoom noj poov uas muaj nyob hauv cov xim tsis muaj xim lossis dawb crystalline hmoov.Kwv yees li 30-38 g yaj hauv dej ntawm 25 ° C.ph ntawm 1% tov ntawm 25 ° C yog 5.2.nws yog siv los ua ib lub khob noom cookie ntxiv dag zog thiab tsw enhancer nyob rau hauv ci khoom thiab raws li ib tug nitrogen qhov chaw rau poov xab fermentation.nws kuj yog siv nyob rau hauv condiments thiab relishes.Lwm lub sij hawm rau ntsev yog ammonium muriate.
Dawb crystals ua los ntawm ammonia ntsev ua raws li hydrochloric acid ua raws li crystallization.Ammonium chloride tseem hu ua sal ammoniac.Soluble hauv dej thiab cawv, ammonium chloride tau siv los ua halide hauv ntau cov txheej txheem, suav nrog cov ntawv ntsev, albumen ntawv, albumen opaltype, thiab cov txheej txheem gelatin emulsion.
