Kaddarorin:
Zinc wani farin ƙarfe ne mai launin shuɗi tare da tsarin hexagonal mai kusa-keɓewa. Yana da ma'anar narkewar 419.58 ° C, wata tafasasshen 907 ° C, wani mawuyacin hali na 2.5, da yawa na 7.14 g / cm³.
Al'adar zinc na zinc ya zo cikin tsarin barbashi biyu: mai sihiri da flake-kamar. Flake-kamar ƙurar zinc yana da ikon sutura mafi girma.
Chise, ƙura zinc a yi sakaci sosai. A cikin yanayin yanayi na yau da kullun, yana samar da bakin ciki, m Layer na asali zinc carbonate a farfajiyar sa, wanda ke hana ci gaba hadawan abu, yin shi sosai lalata a cikin yanayi. Koyaya, ba mai tsayayya da lalata a cikin acidic ko alkalin alkaline. Yana narke a cikin Inorganic acid, bots, da kuma acetic acid amma shine insolble cikin ruwa.
Alinc ƙura da ke ƙonewa tare da farin harshen wuta a cikin oxygen amma yana da wuya a kunna iska a cikin iska, don haka ba a rarraba shi azaman mai ƙarfi. A cikin yanayin al'ada, ƙurar zinc ɗin yana aiki da danshi ko ruwa don samar da iskar gas, amma yawan kayan hydrogen ne in mun gwada da 1 l / (KG · h. Sabili da haka, an rarraba ƙurar zinc a matsayin abu wanda yake samar da gas mai harshen wuta akan ruwa. Koyaya, don ajiya mai aminci da sufuri, yana da kyau a bi da shi azaman aji 4.3 masu haɗari lokacin rigar). A halin yanzu, ƙa'idodi akan ajiya da jigilar zinc na zinc foda ya bambanta a cikin yankuna daban-daban a China, tare da wasu mafi mahimmancin aiki da sauransu suna ƙaruwa.
Dorwar zinc zai iya fashewa a cikin iska, tsari da ya shafi batun haduwa da gas. Misali, micron-sized zinc na sized zinc yana da kyakkyawan jinkirin da aka yi bata lokaci na 180 ms, tare da iyakar fashewar fashewar 1500-2000 g / m m³. A maida hankali ne na 5000 g / M³, ya kai matsayin matsanancin tashin hankali, matsakaicin faduwa ta tashi, kuma mafi girman bayanan watsawa, 46.67 Mpap / s, da kuma 12.47 Hadarin fashewar fashewar Micron-sized zinc foda yana rarrabewa kamar yadda ST1, wanda ke nuna haɗarin fashewar fashewar cuta.
Hanya Hanya:
1. UPSTREAM-zinc ore smelting:
Kasar Sin tana da yawan albarkatun zinc na zinc na zinc na zinc, na kusan kusan kashi 20% na ajiyar duniya, na biyu kawai Australia. Kasar Sin kuma babbar masana'antar zinc ore, tana ba da gudummawa sama da kashi daya bisa uku na samarwa duniya, duniya ta fara. Tsarin smelting ya shafi sake fasalin zinc ore don samun zinc sulfide mai da hankali, wanda a rage zuwa tsarkakakkiyar zinc ta hanyar hydretallatchatics, sakamakon shi da zinc etuns.
A shekarar 2022, Zinot Ingot ya kai talakawa 6.72 miliyan. Kudin zinc na zinc na ƙarshe yana yanke hukunci game da farashin foda mai narkewa, wanda za a iya kiyasta a 1.15-1.2 sau farashin zinc ens.
2. Hanyar zinc
Babban tsarkakakku (99.5%) Ingantaccen zinc yana mai zafi zuwa 400-600 ° C a cikin maimaitawa ko wutar muryar ruwa har sai da narkar da. An canza zinc ana canjawa zuwa mai tsauri da kuma atomized a ƙarƙashin mai mai zafi da kuma haɗawa da yanayi, tare da iska mai zurfi a matsin lamba na 0.3-0.6 MPa. An tattara foda da atomized zinc yana tattarawa a cikin mai karbar ƙura sannan ya wuce sieve mai siyar da ɗaci mai yawa don raba shi cikin daban-daban barbashi mai girma dabam kafin ɗaukar hoto.
3. Hanyar zinc na ƙura-ƙura
Wannan hanyar na iya zama ko dai bushe ko rigar, samar da bushe bushe flake zinc ƙura ko manna-kamar flake zinc ƙura. Misali, down ball milling na iya samar da manna-kamar flake zinc ƙura slurry. A atomized zinc foda yana hade da aliphatic hydrocarts da karamin adadin mai tsami a cikin injin mill. Da zarar an sami nauyin da ake so da flake tsari, slurry yana tace don samar da kayan tacewa tare da sama da 90% zinc zinc zinc zinc zinc zinc zinc zinc zinc. An haɗu da cake ɗin tace don samar da ƙurar zurin zinc na slurry don mayafin gashi, tare da abun ciki na ƙarfe sama da 90%.
Amfani:
Dorwar zinc da farko ana amfani da shi a cikin masana'antar suttura, kamar a cikin kwayoyin halitta da na ciki mai lalata da aka lalata. Hakanan ana amfani dashi a cikin Dyes, Metallgy, sunadarai, da magunguna. Asusun masana'antu na cyings na kusan kashi 60% na Buƙatun abinci na Zinc na Zinc na Zinc
Alincin zinc zinc ya ƙunshi ƙananan ƙwayoyin cuta masu tsari, gami da ƙura ƙura ƙura da ɗaci-mai kyau high-dust. Latterarshe tana da abun cikin zinc na zinc, ƙananan barbashi, kyakkyawan aiki, kunkuntar girman barbashi, da kuma kyakkyawan samfurin. Ultra-mai kyau high-aiki ana amfani dashi sosai a cikin coxroation da rigakafin aikace-aikacen lalata, musamman a cikin firayim da aka yi amfani da shi kai tsaye ga rigakafin rigakafin sanyaya. A cikin suttura, zinc ƙura tare da girman barbashi ƙasa da 28 μm ana amfani da shi. Babban aiki mai kyau-lafiya zinc yana adana albarkatu, yana inganta haɓakar amfani, da haɓaka ke da aikin anti-corroups, suna ba da babban cigaba.
Flakey zinc na ƙura mai kama da tsarin flake yana da tsari mai haske kuma ana samar da shi ta hanyar Milling Milling ko ajiyar jiki (PVD). Yana da babban al'amari rabo (30-100), mai kyau mai yaduwa, rufe, da kariya kaddarorin, kuma ana amfani dashi a cikin sutturar suttur. Flakey ƙura ƙura, ikon iyawar wuta, ikon haɗakar aiki, ikon kare, kariya, ƙarfin kare, da kuma ƙarfe mai ƙarfi idan aka kwatanta da spherical zinc foda. A Dancromet sutturori, flake zinc onits kwance kwance, samar da yadudduka iri ɗaya tare da hulda da fuska, inganta fuska tsakanin zinc da kuma a tsakanin zinc na zinc. Wannan yana haifar da hanyar shafi mai denser, ƙayyadadden hanyoyin lalata lalata hanyoyin lalata da kuma amfani da kauri, da haɓakar kariya da kaddarorin lalata. Anti-Colosion sutturar da aka yi da ƙurar ƙura mai gishiri mafi kyau fiye da gishirin, tare da ƙananan matakan sanannun kaya, tare da ƙananan buƙatun karewar muhalli, haɗuwa da bukatun kariya na muhalli.
