Konke malunga neZinc chloride: Ukusetyenziswa, iMathiriyeli ekrwada, kunye neendlela zokuGcina eziFanelekileyo

Iipropathi ze I-zinc chloride

I-Zinc chloride (ZnCl₂) yikristale emhlophe okanye engenambala ene-solubility ephezulu. Inokuchithwa ngokupheleleyo emanzini, i-ethanol kunye ne-glycerol. Izinzile ngokwekhemikhali, kodwa i-hygroscopic. Xa ibonakaliswe emoyeni, iya kutsala ngokuthe ngcembe amanzi ukwenza i-hydrates. I-zinc chloride inobungozi kakhulu, inokunyibilika iintlobo zetsimbi kunye ne-organic matter, kwaye inetyhefu, ngoko kufuneka iphathwe ngononophelo.

Ukusetyenziswa kwe-zinc chloride

I-zinc chloride inoluhlu olubanzi lwezicelo kwishishini. Kwintsimi yokulungiswa kwesinyithi, isetyenziswe njenge-flux ye-welding kunye ne-brazing, enokuthi isuse ngokufanelekileyo i-oxides kwindawo yesinyithi kunye nokuphucula umgangatho we-welding. Kwishishini lemichiza, i-zinc chloride iyona nto ibalulekileyo kwi-organic synthesis reactions kwaye ihlala isetyenziselwa ukuhlanganiswa kwedayi, iziqholo kunye ne-pharmaceutical intermediates. Ukongezelela, i-zinc chloride iphinda isetyenziswe njengento yokugcina imithi, i-rust remover kunye ne-electrolyte kwiibhetri. Kumzi mveliso welaphu, isetyenziselwa ukulinganisa ilaphu kunye nonyango ukonyusa amandla kunye nokunganyangeki kweentsinga.

Entla nasezantsi imathiriyeli ekrwada ye-zinc chloride

Ukuveliswa kwe-zinc chloride kufuna izinto ezimbini eziphambili: i-zinc kunye ne-hydrochloric acid. I-Zinc yeyona nto iphambili yemathiriyeli ekrwada imveliso ye-zinc chloride. Ngokuqhelekileyo ikhutshwa kwi-ore kwaye inyibilikiswe ukufumana i-zinc ecocekileyo. I-Hydrochloric acid yenye into ebalulekileyo ekrwada, eveliswa ngokusabela kwe-hydrogen kunye neklorini. Kwinkqubo yokuvelisa ngokwenene, i-zinc isabela nge-hydrochloric acid ukuvelisa i-zinc chloride kunye ne-hydrogen. Iimveliso ezisezantsi zibandakanya iimveliso ezahlukeneyo ze-zinc chloride ezisetyenziselwa i-welding, i-brazing, i-catalysts kunye nezinye iindawo. Ezi mveliso zidlala indima ebalulekileyo kwiinkalo ezahlukeneyo zoshishino.

Inkqubo yokuvelisa i-zinc chloride

Ukuveliswa kwe-zinc chloride kuqhutyelwa ikakhulu ngokudibanisa ngokuthe ngqo, oko kukuthi, ukusabela kwe-zinc yensimbi kunye ne-hydrochloric acid ukwenza isisombululo se-zinc chloride, kwaye i-zinc chloride eqinile ifunyenwe ngokunyuka kwe-evaporation kunye ne-crystallization. Iimeko zokusabela kufuneka zilawulwe ngokungqongqo ngexesha lenkqubo yokuvelisa ukuqinisekisa ukuba i-chloride ye-zinc eyenziwe inobunyulu obuphezulu kunye nomgangatho ozinzile. Imveliso ye-hydrogen eveliswa ngexesha lemveliso inokuphinda isetyenziswe njengegesi yeshishini ukuphucula izibonelelo zoqoqosho kwimveliso.

Indlela yokugcina i-zinc chloride

I-Zinc chloride i-hygroscopic kakhulu kwaye i-corrosion, ngoko ke kufuneka kuthathelwe ingqalelo ekhethekileyo xa uyigcina. I-zinc chloride kufuneka igcinwe kwindawo eyomileyo, enomoya ococekileyo ukuze ugweme ukudibanisa nokufuma. Izikhongozeli zokugcina kufuneka zenziwe ngezinto ezikwaziyo ukumelana nomhlwa njengeplastiki okanye iglasi kwaye zivalwe kakuhle ukuthintela ukufuma ekungeneni emoyeni. Iindawo zokugcina kufuneka zigcinwe kude nezinto ezinokutsha neziqhumayo kunye neekhemikhali ezinjengeeasidi ezinamandla kunye neealkali ukuthintela ukusabela okungalindelekanga.

Ukuphathwa ngokukhuselekileyo kweZinc chloride

Ekubeni i-zinc chloride inobuthi kwaye inetyhefu, amanyathelo afanelekileyo okukhusela kufuneka athathwe xa uphathwa. Abaqhubi kufuneka banxibe iimpahla ezikhuselayo, iiglavu kunye neglavu ukuphepha ukudibana ngokuthe ngqo kwesikhumba kunye namehlo nge-zinc chloride. Emva kokuba uqhagamshelwano lwenzeka, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza. Xa uphatha inkunkuma ye-zinc chloride, imimiselo yokukhusela indawo yendawo kufuneka ilandelwe kwaye unyango olufanelekileyo olungenabungozi kufuneka lwenziwe ukuze kuphephe ukungcoliswa kwendalo.

Uhlalutyo lweMarike yeZinc kloride

Imfuno yentengiso ye-zinc chloride igxile kakhulu kwimimandla ye-welding, i-brazing, i-catalysis yeekhemikhali kunye nokugcinwa kweenkuni. Ngophuhliso lwala mimandla yemizi-mveliso, imfuno yentengiso ye-zinc chloride ikwabonisa indlela yokunyuka. Ngokukodwa kumazwe asakhasayo, inkqubo yoshishino iyakhawuleza kwaye imfuno ye-zinc chloride ikhula ngokukhawuleza. Imithetho engqongqo yokusingqongileyo ikwakhuthaze imfuno yeemveliso ze-zinc chloride ezisulungekileyo. Lilonke, imakethi ye-zinc chloride inamathemba abanzi, kodwa ikwajongene nemingeni efana nokuguquguquka kwamaxabiso ezinto ezikrwada kunye nokunyuka kweendleko zemveliso.

Indlela yokuphuhlisa ikamva ye-zinc chloride

Kwixesha elizayo, iindawo zokusetyenziswa kwe-zinc chloride zinokukwandiswa ngakumbi. Ngokomzekelo, kwintsimi yeebhetri zamandla amatsha, i-zinc chloride kulindeleke ukuba isetyenziswe njengento entsha ye-electrolyte ukuphucula ukusebenza kunye nobomi beebhetri. Ngophuhliso loshishino lweekhemikhali eziluhlaza, ukusetyenziswa kwe-zinc chloride kwi-catalysts ehambelana nokusingqongileyo kunye neenkqubo zeekhemikhali eziluhlaza ziya kufumana ingqwalasela engakumbi. Inkqubo yokuvelisa i-zinc chloride iya kuphuhlisa kwindlela yokusebenza kakuhle, ukonga amandla kunye nokukhuselwa kwendalo ukuhlangabezana neemfuno zeemarike kunye neemfuno zokukhuselwa kwendalo.

ukuququmbela

Njengomathiriyeli obalulekileyo weekhemikhali kunye nephakathi, i-zinc chloride idlala indima ebalulekileyo kwishishini. Iimpawu zayo zeekhemikhali ezibalaseleyo kunye noluhlu olubanzi lwezicelo zenza ukuba ngumdlali obalulekileyo kwimarike. Ngokulungisa inkqubo yokuvelisa kunye nokomeleza ulawulo lokhuseleko, ukusebenza kakuhle kwemveliso kunye nomgangatho we-zinc chloride unokuphuculwa ngokufanelekileyo. Kwixesha elizayo, kunye nokuqhubela phambili kweteknoloji yezoshishino kunye nokuphuculwa kweemfuno zokukhusela indalo, amathuba okusetyenziswa kwe-zinc chloride aya kuba banzi.
