1. Gabatarwa zuwa Zinc Zinc, alamar sunadarai Zn, lambar atomic 30, ƙarfe mai juyawa ne. Zinc ana rarraba shi sosai a cikin yanayi kuma yana ɗaya daga cikin mahimman abubuwan da ke cikin halittu masu zaman kansu. Ana amfani dashi sosai a masana'antu na masana'antu, gini, sufuri, magani da sauran filayen. Sunan zinc ya fito ne daga Latin "zinco", wanda ke nufin "tin-kamar ƙarfe" saboda a zamanin da, zinc yana da sau da yawa rikicewa tare da tin.
2. Kayan jiki na launi na zinc na launi da luster: tsarkakakken zinc na da siliki fari tare da ƙarfe luster. A cikin iska, zinc surface zai sannu a hankali oxidize, samar da fim-farin-farin zinc oxokode fim. Yawansu da Melting Points: yawan zinc kusan 7.14g / cm³, meling aya shine 907 ℃. Wannan yana sa zinc yana da kayan aiki mai kyau a yanayin zafin wuri kuma ya dace da masana'antun masana'antu. Cutar ciki da aiki: Zinc yana da wasu tsattsauran ra'ayi da aiki kuma ana iya kusantar da su cikin filaye ko kuma an matse shi cikin gilashin tagulla da aluminum. Taurin kai: Zinc yana da ƙarancin ƙarfi, amma wuya da ƙarfin sa da ƙarfi za a iya ƙaruwa ta hanyar biyan bukatun filaye daban-daban.
3. Abubuwan sunadarai na zinc suna da oxygen: zinc na iya amsawa da oxygen a cikin iska don samar da oxide. 2Zn + ₂ = 2ZNo yana amsawa tare da acid: zinc na iya amsawa tare da marasa kututtukan da ba a wadataccen o} acid din zinc silts da hydrogen. ZN + H₂so₄ = zno₄ + H₂↑
Zn + 2hcl = zncl₂ + H₂↑ zai iya amsawa da alkalin bayani mai warkarwa da gas. Zn + 2Taoh = Na₂zno₂ + H₂↑ na iya yin amsa da gishiri: Magani mai narkewa da gishiri, da kuma maganin gishiri, da sauransu zn + cuso₄ = zno₄ + cu
Zn + 2Arno₃ = zn (no₃) ₂ + 2ag
4. Kasancewa da tsari da hakar zinc (1) Rayuwa SPHARERLALE: ZTTH YANZU NE A STHERAITE. Babban bangaren na sparlerite shine zinc sulfide (Zns), wanda yawanci ya ƙunshi wasu abubuwa na baƙin ƙarfe da kuma jagoranta. Sauran ma'adinai: zinc kuma ya kasance a wasu ma'adanai, kamar Smithsonite (babban aiki shine zn₄si₂o₇ (₂ स · HOTO), tsari (na biyu), da sauransu (2) MINED Daga nawa ya karye, nunawa, grading da sauran hanyoyin, ore tare da mafi girma zinc zinc zinc. Tushen: zaɓaɓɓen ƙirar an gasa don inganta ragi da daraja na nor. Smelting: Yi amfani da pyrtretallurgy ko hydrometallurggy don canza sulfiyar zinc na ƙarfe cikin ƙarfe zinc. Pyrtretallgy yafi haɗa da matakai kamar distillation da raguwa; Gydrometallurgy galibi suna amfani da reacts na sinadarai don narke zinc daga nor. 2zns + 3o₂ = 2ZNo + 2so₂↑
Zno + c = zn + co ↑
5. Aikace-aikace na zinc (1) Aikace-aikacen Galvanizing a rayuwar yau da kullun: zinc yana da kyau a lalata juriya, saboda haka ana amfani da shi don galvanizing jiyya a kan ƙarfe. Misali, galvanized ir bututun, bututun ƙarfe, da sauransu: zinc yana taka muhimmiyar rawa a cikin masana'antar batir. Misali, batura bushe, batutuwa na ajiya, da sauransu duk suna amfani da zinc a matsayin mummunan abu na electrode. Alloy kayan: zinc alloy mai kyau na kyawawan kayan jefa kuri'a da kayan masarufi kuma ana amfani dashi sosai wajen sarrafa sassa daban-daban da kayan ado. (2) Aikace-aikacen Aikace-aikacen SMELTING: Zinc ana amfani dashi azaman deoxizer da desulfurizer a cikin smulting tsari, wanda zai inganta inganci da aikin ƙarfe. An yi amfani da masana'antar sinadarai: zinc ana amfani dashi sosai a cikin masana'antu, dyes, castysts, da sauransu A matsayin shiga cikin tsare-tsaren ayyukan enzyme da inganta aikin kwayar rai. Sabili da haka, an yi amfani da zinc sosai a cikin Kiwon lafiya, kamar kula da karancin zinc da rashin kariya.
