Ammonium hydroxide thiab nws siv

Ob peb cov neeg paub hais tias ib tug tshuaj compound nrog ib tug complex mis NH4OH hu ua ammonium hydroxide ua nyob rau hauv peb lub neej txhua hnub nyob rau hauv ntau guises. Qhov no fertilizer rau qos yaj ywm thiab qab zib beet, nws yog ammonia, cov khoom noj no additive, nkaum nyob rau hauv lub Hoobkas khoom noj nyob rau hauv lub mysterious pseudonym E527, thiab txawm ... dej ntsuab. Rau cov tshuaj kev lag luam uas tshuaj tebchaw rho tshuaj synthetically. Thiab nws ua hauj lwm pab raws li ib tug raw khoom rau pa thee. Nyob rau hauv coke ncu thee tawm ammonia, thiab cov uas twb noo nrog dej nyob rau hauv ntau yam proportions.

Raws li ntub txaus ammonium hydroxide - ib co ntawm nws, thiab tau txais. Piv txwv li, E527, yog li ntawd peb mej nqus ib questionable zoo tuav yog ib tug 25% ammonia tshuaj. A 18% tshuaj Ib txhia housewives thiab thov lawv tus kheej - nws yog lub npe hu raws li ib tug ua noj ammonia dej. Hais txog qhov feem pua muaj pes tsawg leeg ntawm lub substance yog mixed rau hauv cov tsiaj pub. Raws li chiv ammonia dej twb siv nyob rau hauv 20,5% tshuaj. Nyob rau hauv cov hauj lwm zoo ntawm nws yog tsis inferior chiv nyob rau hauv cov hmoov daim ntawv - nitrates thiab ammonia.

Nyob rau hauv kev lag luam, ammonium hydroxide yog siv nyob rau hauv qhuav ntawm dyes, Ferro-manganese. Nws yog siv los tsim dej qab zib tshauv. Cov kev siv ntawm cov ammonia dej yog siv los tiv thaiv lub valve tiv thaiv corrosion. Nws kuj ntxiv mus rau lub MAAs, yog li ntawd nws yog lawm hardens thiab nws yog ib qho yooj yim rau nruab. Muaj ntau cov neeg tsav tsheb yuav tau nrog cov tshuaj ntawm no veschestva- nws yog siv rau zus tau tej cov dej ntsuab. Nws tseem yog tseem ceeb rau txoj kev loj hlob ntawm nitrate.

Nyob rau hauv cov tshuaj, ammonium hydroxide yog pom luag lub feem ntau lug siv. Kaum feem pua tshuaj rho los ntawm syncope thiab ntuav noj raws li pungent tsis hnov tsw ntawm ammonia tsub kom tus nqi ntawm kev ua pa thiab elevates cov ntshav siab. Txawm li cas los, paj rwb ntaub plaub nrog ammonia yog tsim nyog los coj mus rau lub qhov ntswg ntawm tus neeg mob mob: nyob rau hauv ib co, tab sis yog ib tug neeg, tus neeg mob, nws muaj peev xwm, on qhov tsis tooj, ua rau ua pa raug ntes. Yuav kom ntxias ib tug gag reflex, ib yam khoom uas xav diluted nrog dej - undiluted ammonia yuav ua rau kub yus lub plab thiab txoj hlab nqos mov phab ntsa, adversely cuam tshuam lub siab. Kab tom, myositis neuralgia thiab cov tshuaj no yog siv raws li muab tshuaj pleev thiab cov neeg phais ntxuav lawv ob txhais tes ua ntej phais nyob rau hauv dej sov so thiab daws qhov teebmeem ntawd ntsev. Tab sis lub yam khoom uas yog txhob nyob rau hauv ib co daim tawv nqaij kab mob (xws li eczema), thiab nws tsis yog tsim nyog yuav tau mus thov nws nyob rau hauv daim tawv nqaij nrog txiav thiab raug mob.

Ib tug hais txog sounding ammonium hydroxide, txawm li cas los, ib tug kiag li nyias muaj nyias ib yam khoom uas yog ammonium carbonate (kuj hu ua ammonium carbonate). Nws kuj tau lug siv nyob rau hauv cov zaub mov kev lag luam, tab sis nyob rau hauv ib tug txawv code xov tooj emulsifier: E 503. Lawm, lub manufacturers hais tias lub emulsifier yog kiag li txawm rau kev kho mob. Lwm emulsifier E 503, ib co unscrupulous manufacturers ntawm npias Brewer lub poov xab hloov. Yav tas los E503 rau ncuav thiab wafers ua los ntawm nqaij offal, thiab tam sim no nws yog tau los ntawm tshuaj synthesis. Tsis muaj kob muaju hostess ammonium yog siv raws li ib tug ci hmoov. Tsis tas li ntawd, qhov no compound yog siv nyob rau hauv lub tua hluav taws thiab rau qhov kev npaj ntawm ammonium ntsev.

Far ntawm Science News for KIDS tej zaum yuav tsis meej pem npe ammonium hydroxide thiab silicon hydroxide. Txawm li cas los, koj yuav tau xwb yeej yam npe. Los ntawm hom ntawm lub caij tshuaj favorably nrog emulsifier rho tawm los ntawm cov thee, thiab tus ntxhiab tsw - ntawm ammonia. Nws kiag li tsis tau noj. Tab sis nws yog zoo yuav tsum tau hnav nyob rau ntawm cov ntiv tes, lub caj dab los yog pob ntseg! Hydroxides thiab oxides ntawm silicon tsim ib tug ncaj sab pab pawg neeg ntawm cov zaub mov nyob ze rau quartz. Qhov no muaj xws li ib tug shimmering gloss matte opal thiab liab carnelian thiab pa taws chalcedony thiab amethyst los yog kom meej raws li ib tug los kua muag, rhinestone.
