Iipropathi, iindlela zokuvelisa, kunye nokusetyenziswa kothuli lwe-zinc

Ifomula yekhemicali: ZN

Ubunzima bemolekyuli: 65.38

Iipropathi:
I-zinc yintsimbi emhlophe ebomvu enesakhiwo esise-hexagonal esineekristali. Inendawo yokunyibilikisa engama-419.58 ° C, indawo yokubila i-907 ° C, ubuqili be-2,5, ukugela kombane kwe-0.02 ωm² / m, kunye nobunzima be-7.14 g / cm³.

I-ZINC SUTHIME SPOSTERS ZIKHONA IZAKHONO ZESIBINI: ISIQINISEKISO NE-FLAKE-NJENGOTHANDO. I-Slake-njengothuli lwe-zinc linamandla amakhulu okugubungela.

Ngokucacileyo, uthuli lwe-zinc lusebenza. Kwiimeko eziqhelekileyo zemospicic, ziyinto ecekeceke, inqabile, ye-munse ye-zinc carbonate yomgangatho wayo, ethintela i-oxidotion, eyenza ukuba ichaphazele kakhulu emzimbeni. Nangona kunjalo, ayinyangeki ukunyanzelwa kwi-acidic okanye i-alkaline ye-alkaline. Inyibilikisa kwi-Inorganic acid, iziseko, kunye ne-acetic acid kodwa ingena emanzini.

Uthuli lwe-zinc luvutha ngedangatye elimhlophe eliqaqambileyo kwi-oxysigen ecocekileyo kodwa kunzima ukunxiba ngomoya oqhelekileyo, ngoko ke awuchazwanga njengesixhobo esinokutsha. Kwimeko eziqhelekileyo, uthuli lwe-zinc uphinda-phinda umswakama okanye amanzi ukuvelisa igesi ye-hydrogen, kodwa ireyithi yemveliso ye-hydrogen icotha, ingaphantsi kwe-1 l / (kg · h. Ke ngoko, uthuli lwe-zinc aluqheliswanga njengento evelisa iigesi ezivuthayo xa unxibelelana namanzi. Nangona kunjalo, ukhuseleko olukhuselekileyo kunye nezothutho, kuyacetyiswa ukuba ikwazi ukuyiphatha njengeklasi 4.3 Izixhobo eziyingozi (izinto eziyingozi xa zimanzi). Okwangoku, imigaqo ekugcinweni kunye nokuhamba kwe-zinc powder iyahluka kuyo yonke imimandla eyahlukeneyo eTshayina, nabanye baba yinto ebaluleke ngakumbi.

Uthuli lweZinc lunokuqhuma emoyeni, inkqubo ebandakanya i-charsution yesigaba segesi. Umzekelo, uthuli lwe-milron-scred lunexesha lokulibazisa ngokugqibeleleyo lwe-180 ms, kunye nomda wokuqhushumba we-1500-2000 g / m³. Kuxinzelelo lwe-5000 G / M³, ifikelela kuxinzelelo oluphezulu lokuqhushumba, i-Plomion Sokuqhumelo Ukunyuka kwenqanaba, kunye ne-0.481 Mpa / 46.67 Mpa / S, ngokulandelelana. Inqanaba le-shozard enobungozi le-minc poder ye-minc ihlelwe njenge-ST1, ibonisa umngcipheko wokuqhuma ophantsi.

Iindlela zemveliso:
I-1. I-ORTREAM-ZINC OR SMBLET:
I-China inezixhobo ezininzi ze-zinc, inika ingxelo phantse i-20% yoovimba behlabathi, yesibini kuphela e-Australia. I-China ikwangumvelisi omkhulu we-zinc ore, igalelo kwisinye kwisithathu semveliso yehlabathi, i-Spapaki yokuqala kwihlabathi liphela. Inkqubo yokunyibilikisa ibandakanya ukucoca i-zulc ore yokufumana i-chinc gxinile, emva koko incitshisiwe kwi-zinc ye-zunc ye-pyromestal okanye i-hydromestalgalsulical, ikhokelela kwi-zincits.
Ngo-2022, i-China ye-chinc ingot ifikelela kwi-6.72 yeetoni ezigidi. Ixabiso le-zinc Ingona ekugqibeleni libeka ixabiso le-chinec powder ye-chinec powder, enokuqikelelwa kwi-1.15-1.2 amaxesha ixabiso le-zincics.

I-2. I-ZINC-KINCY YOKWENZA INDLELA YOKUZIPHATHA: **
I-chalty ecocekileyo (99.5%) ye-ZINCTS ikhathazwa kwi-400-600 ° C kwi-reverberatory okanye i-terberatory de the velete. I-shoton zunc idluliselwe kwi-Atomictory enqabileyo kwaye ifakwe phantsi kweemeko ezishushu kunye ne-inshurensi, ngomoya oxinzelelweyo kwi-0.3-0.6 MPA. Umgubo we-Atomid Winc uqokelelwa kumqokeleli wothuli waza emva koko wadlula kwi-SEARTINA YOKUGQIBELA YOKUZIPHATHA NGOKUGQIBELA UKUZE UQEQESHE APHA NGaba ukupakisha.

I-3. I-Zinc nothuli lweLill
Le ndlela inokuba yomile okanye imanzi, ivelise uthuli lwe-fincly elc okanye icofe i-slake zinc uthuli. Umzekelo, imilinga yamanzi emanzi inokuvelisa i-paste-njenge-slake ye-fincree uthuli. I-Atomited i-zinc powder ixutywe ne-Aliiphatic hydrocarbon izinyibilikisi kunye nenani elincinci le-oyile kwilitha yebhola. Nje ukuba ubuhle obunqwenelekayo kunye nolwakhiwo lweflaki lufezekiswa, i-slirry icociwe ukuba yenze ikhekhe lokucoca ngaphezulu kwe-90% ye-zinc. Ikhekhe lokucoca i-filter emva koko ixutywe ukuvelisa uthuli lwe-zinc

IISEBE:
Uthuli lweZinc ngokuyintloko lusetyenziswa kwishishini lempahla, njengokusebenzisa i-organic kunye ne-inorganic ze-winc-chines anti-combooings anti-scoasions. Ikwasetyenziswa nakwidasi, i-metallgy, iikhemikhali, kunye namayeza. Ishishini le-Poats i-Akhawunti malunga neepesenti ezingama-60 zeBango loMgubo weZinc, ilandelwa lishishini lekhemikhali (28%) kunye neshishini lamachiza (4%).

Uthuli lwe-zinc luqhutywa phantse amasuntswana aphambili, kubandakanya uthuli lwe-zinc oluqhelekileyo kunye ne-ultra-tench right right uthuli. Le yokugqibela inemixholo ephezulu ye-zinc, ukungcola okuphantsi, i-chirical egudileyo, umsebenzi olungileyo, umphezulu we-oxidation, ubungakanani be-subrow ye-insudation, kunye nemveliso yokusebenza kakuhle. Uthuli lwe-Iltra oluphezulu lwe-Ultra lusetyenziswe ngokubanzi kwi-cayishini kunye nezicelo zokulwa nokuchasana nezixhobo ze-zinc okanye zisetyenziswa ngokuthe ngqo kwi-anti-scoation pays. Kwingubo, uthuli lwe-zinc kunye nobungakanani obungaphantsi kwe-28 μm isetyenziswa ngokuqhelekileyo. Ukusebenza kakuhle kwe-Ultra-Colly Colly LinC igcina izixhobo, iphucule indlela yokusebenzisa izixhobo, kunye nokuphucula ukuqeqesha ukuntywila kokuntywila, ukuhambisa amathemba entengiso ngokubanzi.

I-Flake Zinc Uluthuli lunesakhiwo esiseflethi kwaye iveliswa yimali yokugaya ibhola okanye i-Vapor yomzimba (PVD). Inomyinge ophezulu (30-100), ukusasazeka okugqwesileyo, ukugubungela, kunye nokukhusela iipropathi, kwaye isetyenziswa ikakhulu kwi-dacromet coatings (i-hinc-aluminum). I-Flake Zinc Uthuli lubonelela ngokugubungela okungcono, amandla okudada, ubudoda obungena bukhali, ubuchule bokukhusela, kunye ne-metallic luster xa kuthelekiswa nomgubo we-zinc powder chinc poder. Kwi-dacromet coatings, uthuli lwe-Flake Zin lusasaza ubugqwirha, lwenza uluhlu lwezinto ezininzi ezifanayo ngoqhakamshelwano lobuso ngobuso, ukuphucula ukuqhutywa kobuso phakathi kwe-zinc kunye ne-suble yentsimbi kunye namasuntswana e-zini. Oku kukhokelela kwi-Debser Coating, indlela eyandisiweyo ye-corrosion, ukusetyenziswa kwe-zinc efanelekileyo kunye nokusebenzisa ubungqingqwa, kunye nokukhusela izinto ezikhuselweyo kunye nokuchasa. I-anti-corrosion coatings eyenziwe nge-flake zinc yothuli lothuli olungcono lokutshiza kune-elektroniki okanye i-dip-dip-dipvanings, i-Depan-Points esezantsi, intlanganiso yoKhuseleko loNgezelelweyo.
