Zinc chloride kanye nekubaluleka kwalo ukuze abantu

Zinc chloride kuyinto ekhuthaza kwamakhemikhali izakhi ezimbili - zinc kanye chlorine - futhi luchazwa ngegama ifomula ZnCl2. Lokhu kwaziswa kuyinto zinhlayiya emhlophe.

Zinc chloride kuyinto okunengqondo oncibilikayo emanzini - ekamelweni lokushisa, solubility salo 80%. Chloride liyancibilika at 322 ° C, futhi amathumba at 722 ° C.

Zinc chloride etholwe ngezindlela ezimbili. Samuntu Okokuqala: zinc noma oxide yayo oncibilikayo hydrochloric acid, ngemva kwalokho ikhambi okuholela ingxube ukuthi ayahwamuka. Samuntu Okwesibili: zinc (liquid) uyabaselwa emfudlaneni chlorine.

Hydrolysis kwenzeka ngesikhathi chloride zinc kanye seka has le ndlela elandelayo: ZnCl2 + H2O = ZnOHCl + HCl. Okulingene, ikhambi etholwe - Acid.

Industrial ukukhiqizwa zinc chloride ikhiqizwa amafomu amabili: okuqinile futhi uketshezi. Ngesimo okuqinile, izidakamizwa kumele kube ngesimo ishq ezimhlophe, bavumela staining okuncane noma yimuphi umbala. Ngo isixazululo of chloride kufanele kube kungekho nto enemibala emihle noma ube luhlaza ukukhanya aphuzi. Isixazululo kungenzeka kancane empunga.

Ngesimo okuqinile, lo ingxenyenamba mass chloride akumelwe ibe ngaphansi kuka 97,7%, e isixazululo - 50%. Zinc chloride akuyona oluvuthayo.

Ingqikithi kuyingozi kakhulu for imvelo kanye ubunjalo babantu: okuqinile has 2 ubuthi. Into nabo isikhumba kanye nolwelwesi lwamafinyila abantu, noma izilwane, kubangela ukucasuka contact eside ngesikhumba kubangela ukusha, buqeda izicubu. Kwakheka ngendlela amanxeba kunzima kakhulu.

Ingozi futhi imele izidakamizwa ngokufaka ipheshana zokuphefumula. Ngemithamo emincane, kudala ukuhlekisa ku ekhaleni nomphimbo nomphimbo, isifuba esomile. Inhalation esiningi chloride bangezwa dyspnoea nalokho okubizwa ngokuthi kwezimila ogobhozayo.

Uma imfuyo kuzofanele amehlo, isisulu esinabo ngempela okukhulu ahlabayo ubuhlungu. Uma amehlo akho, engahashazanga ngokushesha, kungase kube ngokungaboni nhlobo noma ngokwengxenye.

Ngenxa ubuthi zinc chloride, phakathi zokuthutha kanye nokusebenzisa kwayo ngokucophelela okukhulu kufanele kuqashelwe. zinc Crystalline chloride zahlanganiswa ngo izikhwama noma imigqomo ka carbon steel, ikhambi uyiswa ekhethekile imiphongolo steel amathangi amakhulu amanzi.

Ethutha impahla wenziwa kokubili ngesitimela futhi umgwaqo, futhi ulwandle ezokuthutha. Ingqikithi is zithutha kuphela linezingxenye avaliwe futhi sonke leso sikhathi eveza umuntu ohluzekile unesibopho ukuqapha ubuqotho emaphaketheni.

Lapho ukusebenza zinc chloride, abasebenzi kudingeka ukugqoka nezinga elifanele lokuhlushwa izidakamizwa emoyeni ovaloli, amagilavu iraba, ukuphepha izibuko futhi respirators.

Kunoma yikuphi akufanele contact nge-zinc chloride emizimbeni amanzi nendle izinhlelo ezivumelekile.

Zinc chloride isetshenziswa ezindaweni eziningi ukukhiqizwa. Isetshenziselwa le impregnation izingxenye lokhuni ngenhloso magciwane (isib ukhuni belele). Le into ehilelekile womshini fibre, udayi eziningi, ukuqinisa eziningi yamazinyo, ukotini, zinc-cyanide, i-aluminiyamu ngisho vanillin. Ngaphezu kwalokho, i-zinc chloride isetshenziswa ukuhlanza metal evele phambi imidwebo, chromium Plating kanye nokunamathisela ngomthofu. indima ebalulekile yalolu ketshezi udlala ukuhlanzwa uwoyela, amalahle izibonelo zalokho ukuhlaziywa kanye womshini amabhethri electrochemical.

Zinc chloride ibuye isetshenziswe ukudaya izimpahla ukotini, ukuthola i-viscose Imicu yotshani njengenhlangano electrolyte - ngenkathi galvanizing. Mhlawumbe ukusetshenziswa ketshezi imithi - njengoba umuthi okuvimba bola; ingadi - njengoba Micronutrient umquba.

Ngaphezu kwalokho, i-zinc chloride, ngenxa yekhono layo brilliant babelamukela ukuncela umswakama emoyeni isetshenziswa njengoba desiccant. Futhi, ingaphambi Irreplaceable umlilo kunjalo, njengoba ehilelekile womshini Foam ukumelana nomlilo izindwangu elifakwe futhi amakhadibhodi.
