Zinc chloride na ya mkpa ụmụ mmadụ

Zinc chloride bụ a chemical compound nke abụọ ọcha - zinc na chlorine - na na-denoted site usoro ZnCl2. A ihe onwunwe bụ a na-acha ọcha kristal.

Zinc chloride ezi uche soluble na mmiri - na ụlọ okpomọkụ, ya solubility bụ 80%. Chloride agbaze na 322 ° C, na Juda na 722 Celsius C.

Zinc chloride na-enwetara na ụzọ abụọ. First n'onwe: zinc ma ọ bụ ya oxide soluble na hydrochloric acid, mgbe nke dapụtara ngwakọta ngwọta e Takọọ. Nke abụọ n'onwe: zinc (mmiri mmiri) bụ kpụ ọkụ n'ọnụ na a iyi nke chlorine.

Hydrolysis n'akparamagwa na zinc chloride na cation nwere ndị na-esonụ usoro: ZnCl2 + H2O = ZnOHCl + HCl. Wednesday dapụtara ngwọta - Acid.

Industrial mmepụta nke zinc chloride na-emepụta na abụọ iche: siri ike na mmiri mmiri. Na ihe siri ike ụdị, umi ga-abụ n'ụdị nke na-acha ọcha flakes, kwere a nta staining ọ bụla na agba. Na a ngwọta nke chloride kwesịrị colorless ma ọ bụ nwere a ìhè acha hue. Ihe ngwọta ya pụrụ ubé ekochiela ihu.

Na ihe siri ike ụdị, uka nta nke chloride ga-erughị 97,7%, na ngwọta - 50%. Zinc chloride abụghị flammable.

Umi bụ nnọọ ize ndụ maka gburugburu ebe obibi na ọdịdị mmadụ: siri ike nwere 2 toxicity. A umi na kọntaktị na akpụkpọ mucous membranes nke mmadụ ma ọ bụ anụmanụ, na-akpata iwe n'ihi na ogologo na kọntaktị na akpụkpọ akpata Burns, corrodes anụ ahụ. Guzobere ndị dị otú ahụ a ụzọ gwọọ ọnyá bụ nnọọ ike.

Danger na-anọchi anya umi abanye akụkụ okuku ume na tract. Na obere doses, ọ na-akpata a otighiti na imi na akpịrị na akpịrị, akọrọ ụkwara. Inhalation nke buru ibu nke chloride nwere ike dyspnoea na-akpọ bubbling respiration.

Ọ bụrụ na umi ka na-anya, na aja na-ele nnọọ oké ọnwụ mgbu. Ọ bụrụ na anya na-anaghị rinsed ozugbo, e nwere ike ịbụ mkpokọta ma ọ bụ ele mmadụ anya n'ihu ìsì.

N'ihi na toxicity nke zinc chloride, n'oge ya njem na ojiji oké ịkpachara anya ga-hụrụ. Crystalline zinc chloride packaged ke akpa ma ọ bụ rụọ nke carbon ígwè, ngwọta gaa pụrụ iche ígwè orù ma ọ bụ tankị.

Ụgbọ njem ihe a rụrụ site ma okporo ígwè na n'okporo ụzọ, na oké osimiri iga. The umi na-ebu naanị na mechiri emechi compartments na niile mgbe n'ikwusara ndị ọrụ onye na iwu ji ya nyochaa ike n'ezi ihe nke mkpo ya anya.

Mgbe na-arụ ọrụ na zinc chloride, ndị ọrụ na-achọrọ na-eyi ihe kwesịrị ekwesị larịị nke ịta nke umi ke ikuku overalls, roba uwe, ugogbe nchekwa na respirators.

Na nke ọ bụla ekwesịghị ikwe na kọntaktị na zinc chloride na mmiri ozu na nsị usoro.

Zinc chloride na-eji ọtụtụ ebe nke mmepụta. Ọ na-eji maka impregnation nke osisi akụkụ na nzube nke disinfection (e.g., osisi sleepers). Nke a na umi abuana ke imewe nke eriri, ọtụtụ e ji esiji ákwà, ọtụtụ eze cements, owu, zinc cyanide, aluminum na ọbụna vanillin. Ọzọkwa, zinc chloride na-eji ọcha metal ebupụta tupu sere, chromium plating na soldering. Ọrụ dị mkpa a umi na-arụ na-adi-ọcha nke mmanụ, coal nlele analysis na imewe nke electrochemical batrị.

Zinc chloride na-eji dyeing owu ibu, inweta viscose esiwọrọ dị ka ihe electrolyte - mgbe galvanizing. Ikekwe na ojiji nke umi ke ọgwụ - dị ka a ọgwụ na-akwụsị na ire ere; ugbo - ka micronutrient nri.

Ke adianade do, zinc chloride, n'ihi na nke na-ghar ejiri anyaukwu ike banye mmiri si ikuku na-eji dị ka desiccant. Ọzọkwa, ọ bụ irreplaceable ọkụ ikpe, dị ka a na-imewe nke ọkụ na-eguzogide ụfụfụ na impregnated akwa na katọn.
