Izakhiwo:
I-Zinc iyinsimbi emhlophe eluhlaza okwesibhakabhaka enesakhiwo se-hexagonal esondelene ne-crystal. Inendawo yokuncibilikisa engu-419.58 ° C, iphuzu elibilayo lika-907 ° C, Ubulukhuni be-MOHS abangu-2,5, ukumelana kagesi kuka-0.02 ω ω · mm² / m, kanye nobunzima be-7.14 g / cm³.
Imibala yothuli lwe-Zinc iza ezinhlanganweni ezimbili eziyizinhlayiyana: okuyindilinga nezimbali. I-Whake-Lint Zinc Uthuli Unamandla Okweqile.
Amakhemikhali, uthuli lwe-zinc lusebenza kahle. Ezimweni ezijwayelekile zomoya, kwakha ungqimba oluncane, olunye oluyisisekelo lwe-zinc carbonate yalo ebusweni bawo, okuvimbela ezinye i-oxidation, okwenza kube nokulimaza kakhulu emoyeni. Kodwa-ke, akumelene nokugqwala kusawoti we-acidic noma we-alkali. Iyancibilika kuma-inorganic acid, izisekelo, kanye ne-acetic acid kepha ayinakufakwa emanzini.
I-Zinc uthuli ivutha ngelangabi elimhlophe eliqhakazile ku-oxygen emsulwa kepha kunzima ukusula emoyeni ojwayelekile, ngakho-ke akuhlukaniswa njengokuqinile okuqinile. Ezindaweni ezijwayelekile, uthuli lwe-zinc luphendula ngomswakama noma amanzi ukukhiqiza igesi ye-hydrogen, kepha izinga lokukhiqizwa kwe-hydrogen lihamba kancane, lingaphansi kwe-1 l / (kg · h). Ngakho-ke, uthuli lwe-zinc aluhlukaniswa njengento ekhiqiza amagesi avuthayo lapho axhumana namanzi. Kodwa-ke, ngokugcina okuphephile kanye nokuhamba, kungakuhle ukukuphatha njenge-Class 4.3 Izinto eziyingozi (izinto eziyingozi uma zimanzi). Njengamanje, imithethonqubo ekugcinweni nasekuthuthweni kwe-zinc powder kuyahlukahluka ngezindawo ezahlukahlukene eChina, kanti ezinye ziba namandla ngokwengeziwe nabanye.
I-Zinc Pust ingaqhuma emoyeni, inqubo ehilela ukuhlanganiswa kwegesi-isigaba segesi. Isibonelo, uthuli lwe-zinc-ubukhulu lwe-micron lunesikhathi esifanelekile sokulibala kwama-180 ms, ngomkhawulo wokuqhuma kwe-1500-2000 g / m³. Eqoqweni elingu-5000 g / M³, lifinyelela ekucindezelweni okukhulu kakhulu kokuqhuma, kanye ne-Polight Express Pressure Index, okuyi-0.481 MPA, 46.67 MPA / 12.67 Mpa · · MPA / ngokulandelana. Ileveli yengozi yokuqhuma kwezinga le-zinc-sises ye-zinc ihlukaniswa njenge-ST1, ekhombisa ubungozi obuphansi bokuqhuma.
Izindlela Zokukhiqiza:
1. Upstream-Zinc ore Smorelting:
I-China inezinsizakusebenza eziningi ze-zinc, i-accounting cishe ama-20% ezindawo zokugcina zomhlaba, owesibili kuphela e-Australia. I-China futhi ingumkhiqizi omkhulu we-zinc ore, enikela ngengxenye eyodwa kwezintathu yokukhiqizwa komhlaba wonke, isikhundla sokuqala emhlabeni jikelele. Inqubo yokushintshana ibandakanya ukuphindaphinda i-zinc ore ukuthola i-zinc sulfide gxila, bese incishiswa ku-zinc emsulwa noma izinqubo ze-hydrometallurlurlical, okuholele eZincots Ingots.
Ngo-2022, ukukhiqizwa kwe-Icot kwe-Zinc Ingot kwafinyelela kumathani ayizigidi eziyi-6.72. Izindleko ze-Zinc Ingots ekugcineni zinquma intengo ye-zinc powder eyindilinga, engalinganiselwa ku-1.15-1.2 izikhathi zentengo ze-zinc ingots.
2. Indlela ye-Zinc Drust-atomization: **
Ukuhlanzeka okuphezulu (99.5%) I-Zinc Ingots ifudunyezwa ku-400-600 ° C in isithando somlilo noma esijikelezayo kuze kuncibilike. I-zinten zinc bese idluliselwa ku-refractical ebekiwe futhi ingena ngaphansi kwezimo ezifudumele nezifakwayo, ngomoya ocindezelwe engcindezini engu-0.3-0.6 MPA. I-atomised zinc powder iqoqwe umqoqi wethuli bese idlula ngesihlungo esivuthayo se-multi-ungqimba sokuyihlukanisa ibe ngamasayizi ahlukene ngezinhlayiya ngaphambi kokupakisha.
3. Indlela ye-Zinc Dust-Ball Minsing: **
Le ndlela ingaba yomile noma imanzi, ikhiqize i-flake ye-zinc yomile noma unamathisele othuli lwe-flake. Isibonelo, ukugaywa kwebhola okumanzi kungakhiqiza unama-flake afana noFlake Zinc Slurry. I-atomized zinc powder ixutshwe ne-aliphatic hydrocarbon solvents kanye nenani elincane lokugcotshwa kwesigayo sebhola. Lapho ukwakheka okufisayo nesakhiwo esifiselekayo kufinyelelwa, ama-slurry ahlungwa ukuze akhe ikhekhe lokuhlunga elinokuqukethwe okungaphezulu kwama-90. Ikhekhe lokuhlunga liphinde lixutshwe ukuze likhiqize iZinnc Dust Slurry ngezigqoko, ngokuqukethwe kwensimbi okungaphezulu kwama-90%.
Sebenzisa:
I-Zinc Pust isetshenziswe ngokuyinhloko embonini yezambatho, njengaku-organic kanye ne-inorganic-zi-anti-corolusion anti-corolusion. Iphinde isetshenziswe kumadayi, metallurgy, amakhemikhali, kanye nemithi yezemithi. Imboni ye-Coatings ibeka cishe ama-60% okufunwa yi-zinc powder, elandelwa imboni yamakhemikhali (28%) kanye nomkhakha wezemithi (4%).
I-Spherical Zinc Pust iqukethe izinhlayiya ezicishe zibe yi-spherical, kufaka phakathi uthuli olujwayelekile lwe-zinc kanye nomoya ophakeme we-zinc ophakeme. Lesi sakamuva sinokuqukethwe okuphezulu kwe-zinc, ukungcola okuphansi, izinhlayiya ezibushelelezi, umsebenzi omuhle, i-oxidation encane ye-oxidation, ukusatshalaliswa kosayizi omncane, kanye nokusatshalaliswa okuhle kakhulu, okwenza kube ngumkhiqizo ophakeme kakhulu. I-Ultra-Fine-Fight-Phina Esebenzayo i-Zinc Pust isetshenziswa kabanzi kuzinkungu kanye nezinhlelo zokusebenza zokulwa nokuwohloka, ikakhulukazi kuma-primers acebile noma asetshenziswe ngokuqondile ezimbozweni zokulwa nokukhulisa. Ezinkotsheni, uthuli lwe-zinc ngosayizi wezinhlayiyana ezingaphansi kwama-28 μm kuvame ukusetshenziswa. Ukusebenza okuphezulu kwe-Ultra-Fine Zinc kugcina izinsizakusebenza, kuthuthukisa ukusebenza kahle, futhi kuthuthukisa ukusebenza kwe-anti-toporion, okunikeza amathemba abanzi emakethe.
I-Flake Zinc uthuli inesakhiwo esifana ne-flake futhi ikhiqizwa yibhola lokugaya kwebhola noma umdwebo we-VVD (PVD). Inesilinganiso esiphakeme kakhulu (30-100), ukusakazeka okuhle kakhulu, ukumboza, kanye nokuvikela izakhiwo, futhi kusetshenziswa ikakhulukazi egqoke ama-dacromet (izimbobo ze-zinc-aluminium). I-Flake Zinc uthule inikezela ukumboza okungcono, amandla athambile, amandla okubopha, amandla okuvikela kanye ne-luster yensimbi uma kuqhathaniswa ne-zinc powder eyindilinga. Ezambeni ze-DACROMET, uthuli lwe-zinc lusakazeka ngokuvundlile, kwakha izingqimba eziningi ezihambisanayo ngokuxhumana ubuso nobuso, ukwenza ngcono ukusebenza phakathi kwe-zinc kanye ne-substrate yensimbi. Lokhu kuphumela ekuhlanganiseni okude, izindlela ezengeziwe zokugqwala, ukusetshenziswa kwe-zinc okulungiselelwe kahle kanye nokuqina okunama-coating, kanye nezakhiwo ezivinjelwe zokuvikelwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokulwa nokubhuka. Imidwebo yokulwa nokugqwala eyenziwe nge-flake zinc uthuli lukhombisa ukumelana nosawoti okungcono kakhulu kune-electropplated noma eshisayo ye-galvanized, enamazinga okungcola aphansi, okuhambisana nezidingo zokuvikelwa kwemvelo.
