I-Ammonium Chloride: IMichiza yeBanga leShishini eliNxulunyanisiweyo

I-ammonium chloride(ebizwa ngokuba yi "ammonium", ekwabizwa ngokuba yi-halogen, ikhemikhali: NH4Cl) yikristale engenambala yetyhubhu okanye umgubo omhlophe wekristale.Incasa inetyuwa kwaye iyakrakra, i-asidi -uhlobo lwetyuwa.Uxinzelelo olunxulumeneyo yi-1.527.Kulula ukunyibilika emanzini kunye ne-ethanol, i-soluble kwi-ammonia engamanzi, kwaye ayinyibiliki kwi-pyruis kunye ne-ether.Isisombululo esinamanzi sibuthathaka kwaye si-acidic, esiphuculweyo xa sifudumeza.Xa ufudumeza ukuya kwi-100℃, iqala ukuguquguquka kakhulu.Xa 337.8 ℃ Chemicalbook, inyibilika ibe ammonia kunye hydrogen chloride.Emva kwengqele, iphinda ivele ivelise iammonium chloride encinci kakhulu.I-Essence Heat ukuya kwi-350 ℃ sublimation, kwaye indawo yokubila yi-520 ° C. Incinci emanzini, kodwa inokufunxa ukufuma kwimozulu yemvula emanzi.I-Corrosion kwintsimbi emnyama kunye nezinye iintsimbi, ngakumbi i-corrosion ye-copper, kwaye ayinayo i-corrosion effect kwi-iron ekrwada.

I-Ammonium chloride1Umlinganiswa:ikristale engenambala okanye umgubo omhlophe wegranular, yi-electrolyte eyomeleleyo enyibilikiswa kwi-ion hydropower kunye ne-chloride ion.Kuya kuba nomsi omhlophe xa kusenziwa i-ammonia kunye ne-hydrogenation ye-hydrogen chloride.Akukho vumba.Incasa inetyuwa kwaye iyakrakra kancinci.Incinci kumanzi afunxayo, kodwa inokufunxa nokufuma kwimozulu yemvula emanzi.I-Pluffal ammonium chloride kulula kakhulu ukuyicombulula, ngakumbi iimveliso eziqeqeshiweyo zininzi kakhulu.Inqaku le-hygroscopic ngokubanzi malunga ne-76%.Xa ukufuma okunxulumene nomoya kungaphezulu kwendawo yokufuma, i-ammonium chloride ivelisa ukufunxa ukufuma kwaye kulula ukuqhina.Inokuthi i-sublimated (okwenene inkqubo yokubola kunye nokulungiswa kwakhona kwe-ammonium chloride) ngaphandle kwamanqaku okunyibilika.Uxinzelelo olunxulumeneyo yi-1.5274.Ixabiso lesaphulelo yi-1.642.Ityhefu ephantsi, isiqingatha sokufa (iimpuku, i-meridian) 1650mg/kg.Iyacaphukisa.Ukufudumala ukuya kwi-350 ℃ sublimation, kwaye indawo yokubila yi-520℃.

Kulula ukunyibilika emanzini, i-soluble kancinane kwi-ethanol, i-soluble kwi-ammonia engamanzi, ayinyibiliki kwi-acetone kunye ne-ether.I-Hydrochloric acid kunye ne-sodium chloride inokunciphisa ukunyibilika kwayo emanzini.Ukunyibilika emanzini yi-29.4g ku-0℃, 33.2g ku-10℃, 37.2g ku-20℃, 41.4g ku-30℃, 45.8g ku-40℃, 50.4g ku-50℃, 60.3g ngo-60℃. 70℃ kunye ne-65.6g ku-80℃.71.2g ku-90℃ kunye ne-77.3g kwi-100℃).Xa ishushubezwa ukuya kutsho kwi-100℃, iqalisa ukubola.Xa ishushubezelelwa kwi-337.8℃, inokubola ngokupheleleyo ibe yigesi yeammonia kunye nehydrogen chloride.Xa kubanda, iphinda iphinde yenze i-ammonium chloride enamasuntswana amancinci kakhulu kwaye iveze umsi omhlophe, ongelula ukutshona kwaye akulula ukunyibilika emanzini.

I-PH yesisombululo esinamanzi: Ngenxa yokuba i-ayoni ye-ammonium hidrolyzed emanzini emanzini yenza ukuba isisombululo sibonakale sineasidi, ixabiso le-pH lesisombululo se-ammonium chloride esihluthiweyo phantsi kobushushu obuqhelekileyo buba malunga ne-5.6.Kwi-25 ° C, i-1% yi-5.5, i-3% yi-5.1, i-10% yi-5.0.I-ammonium chloride ngokwayo ingasetyenziselwa njenge-reagent ezinzileyo yeekhilikithi kunye ne-pupa (ukubonelela nge-chloride ion ukuhambelana, kunye ne-compounds iyachithwa kwi-dilute hydrochloric acid kunye ne-chloride ngexesha lokusetyenziswa).

Iimpawu zekhemikhali:

Isisombululo se-aqueous sinobunzima be-asidi, ephuculweyo xa kushushu.I-Corrosion kwintsimbi emnyama kunye nezinye iintsimbi, ngakumbi i-corrosion yobhedu, kwaye ayinayo i-corrosion effect kwi-iron eluhlaza;ukuxuba igesi ye-ammonia kunye negesi ye-hydrogen chloride iya kuveliswa ngumsi omhlophe, kwaye umsi omhlophe yi-ammonium chloride;

Isicelo:

1. Ingasetyenziswa njengezinto eziluhlaza, ukuvelisa iibhetri ezomileyo kunye neebhetri, ezinye iityuwa ze-ammonium, izongezo ze-electroplating, iifeldients zensimbi ze-welding;

2. Kwizongezo zokudaya, kukwasetyenziselwa i-tin-plated kunye negalvanized, isikhumba solusu, iyeza, amakhandlela, izinto zokuncamathelisa, i-chromium -seepage, kunye ne-precision casting;

3. Amayeza, ibhetri eyomileyo, ukuprintwa kwelaphu kunye nokudaya, isepha;

I-Industrial grade ammonium chloride isetyenziswa ikakhulu kwiibhetri, i-electroplating, ukudaya, ukugalela, iyeza, ukuthontelana, i-fluff, i-chemical intermediates njalo njalo.

I-Ammonium chloride ingasetyenziswa njengesichumiso senitrogen kwezolimo, kwaye indlela yayo iyafana neye-ammonium sulfate, kodwa ukusetyenziswa kwe-ammonium chloride kubangela ukuba umhlaba ube neasidi embi ngakumbi kune-ammonium sulfate.Ingasetyenziswa njengesichumiso esisisiseko, isichumiso sokufaka phezulu, asinakusetyenziswa njengesichumisi sembewu.Ukongezelela, kwizityalo ezixhathisa i-chlorine (icuba, iswekile, iitapile, njl.) ayinakusetyenziswa ngobuninzi.

Ukupakisha:Isingxobo ngasinye singama-25Kg okanye ama-50Kg afakwe ingxowa yeplastiki kunye nengxowa elukiweyo yangaphandle.

Ammonium chloride2Kwinkampani yethu, sibonelela ngenqanaba eliphezulu lemveliso ye-ammonium chloride ukuhlangabezana neemfuno zeshishini lakho.Imveliso yethu ihlangabezana nayo yonke imigangatho yoshishino kwaye ifumaneka ngeendlela ezahlukeneyo, kuquka iikristale kunye nomgubo.

Ukuqukumbela, i-ammonium chloride yikhemikhali yomgangatho wemveliso eguquguqukayo kunye noluhlu oluninzi lokusetyenziswa.Iyinxalenye ebalulekileyo yemizi-mveliso yanamhlanje, nto leyo eyenza ukuba ibe yimpahla exabisekileyo kwihlabathi lanamhlanje elikhawulezayo.Khetha imichiza ye-ABC kuzo zonke iimfuno zakho ze-ammonium chloride, kwaye ube namava okuzinikela kwethu kumgangatho kunye nenkonzo.
