Ammonium tshuaj dawb. Cov kev siv, cia thiab nqi

Ammonium tshuaj dawb nyob rau hauv lub ntim rau kev siv (technical ammonium tshuaj dawb) yog ib qho outwardly hmoov khoom tus me nyuam xaiv yog tau nyob rau hauv daim ntawv ntawm granules. Cov xim daj los yog liab, cov xim hloov nyob rau hauv lub npe ntawm cov khoom. Nws yog zoo yaj nyob rau hauv ammonia thiab dej, saj qab ntsev, tsis hnov tsw.

Neeg kho tshuab engineering thiab nonferrous metallurgy, tshuaj thiab hluav taws xob engineering, ntoo thiab txua ntoo, kev kho mob thiab ntau lwm yam lag luam yog siv nyob rau hauv lawv cov kev ntawm ammonium tshuaj dawb. Thoob plaws siv ntawm ammonium tshuaj dawb twb pom nyob rau hauv ua liaj ua teb raws li ib tug nitrogenous chiv, metallurgy siv nws thaum lub sij hawm hlau etching. Domestic textiles yuav poob brightness ntaub so ntswg yog tias tso tseg kev siv ntawm no compound. Ammonium tshuaj dawb tau pom daim ntawv thov nyob rau hauv qhov siv thiab ua qhuav roj teeb, nws copes nrog tinned steel qhov chaw nrog flux (ZnCl2). Raws li ib tug kho mob lub cuab tam, nws yog siv nyob rau hauv cov tshuaj, kws kho rau edema, qhov uas yog txuam nrog rau cov chaw ua hauj lwm ntawm lub plawv, NH4Cl kuj pab tau kev txiav txim ntawm ib co diuretics. Qhuav ntawm ib co cov xim tsev thiab adhesives raws li nyob rau kev siv ntawm ammonium tshuaj dawb nyob rau hauv muaj pes tsawg leeg hardeners.

Thauj thiab cia nyob rau hauv warehouses NH4Cl yuav ntim ntawm lub substance nyob rau hauv lub neej coj multilayer hnab ntawv los yog hnab yas. Lawv cov luj, feem ntau tsis ntau tshaj 25 kg. Nws yog tseem tau mus siv pov tseg mos mos tshwj xeeb ntim.

Kev mus los rau ammonium tshuaj dawb tso cai rau siv ib tug ntau ntawm cov tsheb gated (tsis suav cov huab cua). Thov mos tshwj xeeb ntim tso cai rau thauj cov mobile muaj pes tsawg leeg ntawm qhib hom uas tsis muaj transshipment rau qhov lawv.

Cov chav nyob rau hauv uas ammonium tshuaj dawb yog yuav tsum tau muab, yuav tsum xyuas kom meej cov kev tiv thaiv ntawm dej ingress rau nws. Chaw rau cia, koj yuav tsum xub luaj lub protruding cov khoom uas ntse hau uas yuav ua kev puas ntawm daim tawv nqaij lub hnab. Lub pov tseg ntim tshwj xeeb tshuaj yuav tsum tau muab cia txawm tawm sab nraud.

Thaum lub sij hawm zus tau tej cov dej qab zib-product muaj pov thawj yuav tsum tau ammonium tshuaj dawb. Kev npaj ntawm no cov ntaub ntawv uas yog nqa tawm los ntawm evaporation ntawm cov niam dej cawv. NH4Cl ywj siab synthesis cov tshuaj tiv thaiv yog tias ammonia reacts nrog hydrochloric acid.

Txoj kev tshawb no ntawm nyob rau hauv vitro zog NH4Cl yuav tsum tau txhim khu kev qha txoj kev los mus txiav txim nws xub ntiag. Zoo tshuaj tiv thaiv nrog ammonium tshuaj dawb, feem ntau txiav txim hauv lub xub ntiag ntawm ammonium ntawv NH4 +.

Yog hais tias thaum lub sij hawm lub ntsev nrog alkali ntsws sis thaum lub sij hawm sov li ammonia yog tso tawm, nws yog tau hais nrog certainty lub xub ntiag ntawm lub substance nyob rau hauv thawj zaug tshuaj ntawm lub ntawv NH4 +. Ammonia vapors yuav pleev xim ntub litmus ntawv, los so rau tam sim no ntawm cov roj ua, nyob rau hauv xiav xim.

Txiav txim seb ib tug thib ob feem ntawm NH4Cl, ib tug chloride anion, ua tau, los ntawm ua yeeb yam nyob rau hauv lub analyzed nyiaj tshuaj. Cov tshuaj tiv thaiv tsos ntawm dawb caseous precipitate qhia namely nag lossis daus nyiaj chloride. Tsis tas li ntawd ntawm ib tug tov nrog cov precipitate ntawm sodium thiosulfate los yog ammonia yuav ua rau nws nyias mus nyias.

Txawm nyob rau hauv cov phau ntawv nyeem nyob rau hauv inorganic Science News for KIDS high school, koj muaj peev xwm nrhiav tau ib tug ntau ntawm cov muaj kev ntsuam xyuas mus rau ntsiab Cheebtsam ntawm ammonium chloride, uas qhia cov txheeb ze muaj kev ruaj ntseg ntawm cov khoom no rau tib neeg.

Tab sis tu thaum kov nws yog tsim nyog, raws li ntog rau ntawm daim tawv nqaij los yog nyob rau hauv lub ob lub qhov muag, nws yuav ua rau voos. Cov kev txaus ntshai yuav tsim secreted lom ammonia roj (4 koom kev ruaj chav kawm ntawv), nws txawm me me ntau ua rau voos ntawm qhov muag thiab Upper pa ib ntsuj av tau, ib tug siab concentration leads mus rau ib exciting txiav txim nyob rau hauv central lub paj hlwb.
