Chaw tsim tshuaj paus zoo li ammonium chloride CAS: 12125-02-9

Ammonium chloride, (qib qeb kawm) ammonium chloride (xa mus rau "chloramine", tseem muaj mis nyuj: NH4Cl) yog cov hmoov daj lossis dawb crystalline. Nws qab qab ntsev thiab me ntsis iab thiab belongs rau cov kua qaub acid. Nws tus txheeb ze ceev yog 1.527. Nws yog soluble hauv dej, ethanol thiab kua ammonia tab sis insoluble hauv acetone thiab ether. Cov kua tshuaj aque yog cov acidic tsis muaj zog, thiab nws cov acidity yog txhim kho thaum cua sov. Thaum rhuab 100 ° C, nws pib loj heev volatilize, thiab thaum rhuab rau ntawm Ammonia thiab hydrogen chliaide, yuav rov ua ke ntawm ammonium chloride thiab cov pa luam yeeb dawb Qhov ntawd tsis yooj yim rau tog thiab nyuaj heev kom yaj hauv dej. Thaum rhuab rau 350 ° C, nws yuav sublate thiab thaum 520 ° C, nws yuav rhaub. Nws nqus dej noo noo yog me me, thiab hauv huab cua ntub dej nag tuaj yeem nqus noo noo rau ncuav mog qab zib. Rau cov hlau ferrous thiab lwm yam hlau, uas yog, tshwj xeeb, muaj ntau dua corrosion tooj liab tab sis tsis muaj hlau ntawm npua hlau. Ammonium chloride tuaj yeem tau los ntawm kev saib xyuas nruab nrab ntawm ammooride lossis ammoorogen chloride lossis ammorodicic acid (tshuaj tiv thaiv kab sib npaug: NH3 + HCL → NH4Cl). Thaum rhuab, nws yuav decompose rau hydrogen chloride thiab ammonia kev tawm tsam (Tshuav: NH4CL → yog tias muaj txoj cai yog tias lub thawv yog qhib system.
Ammonium chloride yog siv rau cov roj teeb qhuav, tshuaj, pleev tshuaj, cov khoom siv nitrogen yog 24% rau 25%. Nws yog lub cev muaj sia ua chiv thiab haum rau cov nplej, nplej, pob kws, rapeseed thiab lwm cov qoob loo. Nws muaj qhov cuam tshuam ntawm kev txhim kho fiber ntau lub zog thiab nro thiab txhim kho kom zoo dua rau cov paj rwb thiab cov qoob loo linen. Txawm li cas los xij, vim muaj xwm txheej ntawm ammonium chloride, yog tias daim ntawv thov tsis yog, nws yuav coj qee qhov tsis zoo rau av thiab qoob loo.
Kev siv kev mob: Kev siv cov neeg koom pheej ntawm Tuam Tshoj lub teb chaws tus qauv GB-2946-82.

Ammonium Chloride yog siv los ua cov tuab thiab ua cov yeeb yaj kiab ntxiv hauv toners. Raws li cov tshuaj kom hniav zoo nkauj, cov kws ua haujlwm ammonium muab cov kev hnov ​​los yog ua lub toners, thiab twg, hauv cov toners ib txwm, feem ntau yog muab los ntawm cov ntsiab lus dej cawv. Ammonium chloride siv yog qhov tshwm sim ntawm kev nyiam ntawm kev tsim qauv.
Ammonium chloride yog lub khob noom cookie txias thiab cov poov xab cov zaub mov uas muaj xim muaju lossis cov hmoov dawb dawb. Kwv yees li 30-38 g yaj nyob rau hauv dej ntawm 25 ° C. Cov PHC ntawm 1% daws ntawm 25 ° C yog 5.2. Nws yog siv ua lub khob noom cookie dag zog thiab tsw ntxiv rau hauv cov khoom ci thiab ua cov nitrogen rau cov poov xab fermentation. Nws tseem siv nyob rau hauv cov khoom haum thiab relishes. Lwm lo lus rau ntsev yog amonium muriate.
Cov muaju xim dawb ua los ntawm ammooria salts ua yeeb yam ntawm hydrochloric acid ua raws li crystallization. Ammonium Chloride tseem muaj lub npe hu ua Salmiac. Soluble hauv dej thiab dej cawv, ammonium chloride tau siv los ua cov ntawv sau, xws li cov ntawv tshaj tawm, albumen oppospe, thiab gelatin emulsion cov txheej txheem.
