Tshuaj mis: Zn
Molecular hnyav: 65.38
Khoom:
Zinc yog lub bluish-dawb hlau nrog lub hexagonal kaw-prystal qauv. Nws muaj lub ntsiab lus melting ntawm 419.58 ° C, lub qhov cub npau npau ntawm 907 ° C, Mohs Distuctivity ntawm 0.02 ω resist²² / m, thiab qhov txawv ntawm 7.14 g / cm³.
Zinc Plua Plav Pigments Los hauv ob qho qauv me me: kheej kheej thiab flake-zoo li. Fine-zoo li zinc plua plav muaj ntau lub zog sib luag.
Chincically, Zinc Plua Av yog ntau heev. Nyob rau hauv ib txwm atmospheric muaj kev mob, nws ua ib qho nyias nyias, ntom txheej ntawm nws cov npoo, uas tiv thaiv kev pab oxidation ntxiv, ua rau nws muaj kev tiv thaiv zoo hauv cov cua. Txawm li cas los xij, nws tsis tiv taus corrosion hauv acidic lossis alkaline ntsev. Nws yaj nyob rau hauv inorganic acids, gases, thiab acetic acid tab sis yog insoluble hauv dej.
Zinc Plua Plav Burns nrog lub nplaim taws ci ntsa iab dawb rau hauv cov pa ntshiab tab sis nyuaj rau cov huab cua ib txwm muaj, yog li nws tsis raug cais tawm cov tawv tawv. Nyob rau hauv ib puag ncig ib puag ncig, zinc plua plav rov qab nrog noo noo los yog dej los tsim hydrogen roj av, tab sis tus nqi ntawm hydrogen roj hmab yog qeeb, deb dua 1 l / (kg h). Yog li ntawd, cov plua plinc plua plav tsis tau cais raws li cov khoom uas tsim cov roj ntsha uas tuaj yeem siv cov dej. Txawm li cas los xij, rau kev nyab xeeb thiab kev thauj mus los, nws raug nquahu kom kho nws ua chav kawm 4.3 cov khoom siv uas muaj kev phom sij thaum ntub dej). Tam sim no, cov cai nyob rau hauv lub chaw khaws khoom thiab tsheb thauj ntawm zinc hmoov sib txawv thoob plaws thaj tsam sib txawv hauv Suav teb, nrog qee tus neeg muaj ntau yam ntxiv.
Zinc Plua Plav tuaj yeem tawg hauv huab cua, tus txheej txheem cuam tshuam nrog roj-theem kev sib txuas. Piv txwv li, micron-medized Ntawm kev sib haum xeeb ntawm 5000 g / mp, nws mus txog qhov siab tshaj plaws tawg siab, ntau kawg yog 0.481 MPa / s, thiab 12.67 mpa · txiv / s, feem ntau. Cov Tawg cov teeb meem txaus ntshai ntawm cov micron-qhov loj zinc hmoov tau cais raws li ST1, qhia tau tias tsis tawg kev pheej hmoo.
Cov Qauv Ntau Lawm:
1. Upsstream-zinc ore smelting:
Tuam Tshoj muaj ntau cov peev txheej zoo tshaj plaws Zinc, cov nyiaj txiag rau ze li 20% ntawm ntiaj teb cov peev txheej, thib ob rau Australia. Tuam Tshoj kuj tseem yog ib qho tseem ceeb tshaj plaws ntawm zinc ore, pab txhawb dua ib feem peb ntawm kev sib luag ntawm lub ntiaj teb, qeb duas thawj thoob ntiaj teb. Cov txheej txheem smelting cuam tshuam nrog zinc ee kom tau zinc sulfide mloog lossis hydrometallurgical cov txheej txheem, ua rau cov txheej txheem zinc.
Xyoo 2022, Tuam Tshoj txoj kev siv Zinc Ntau lawm tau mus txog 6.72 lab tons. Tus nqi ntawm cov Sincing Intots kawg txiav txim siab tus nqi ntawm spherical zinc hmoov, uas tuaj yeem kwv yees ntawm 1.15-12 tus nqi ntawm cov nqi zinc.
2. Zinc plua plav-atomization txoj kev: **
High-Purity (99.5%) Zinc Ingots yog rhuab rau 400-600 ° C hauv kev sib tw lossis cov huab cua rauv kom txog thaum molten. Tus Molten Zinc yog pauv mus rau ib qho kev sib dhos ua ke ntawm cov crucible thiab atomized nyob rau hauv rhuab thiab insulated cua nyob rau ntawm lub siab ntawm 0.3-0.6 mpa. Lub atomized zinc hmoov yog sau rau hauv cov plua plav collector thiab tom qab ntawd dhau los ntawm ntau-txheej vibrating sab nrauv kom nyias muaj ntau thiab tsawg ua ntej ntim.
3. Zinc Plua Plav-Pob Milling txoj kev: **
Hom no tuaj yeem qhuav los yog ntub dej, ua kom qhuav flake Zinc Pluard lossis paste-zoo li taws flake zinc hmoov av. Piv txwv li, ntub pob milling tuaj yeem tsim cov tshuaj txhuam-zoo li flake zinc plua plav slurry. Atomized zinc hmoov yog tov nrog aliphaatic hydrocarbon cov kuab tshuaj thiab cov roj nplua nyeem me me hauv pob zeb. Thaum qhov xav tau cov txiaj ntsig zoo nkauj thiab cov kab nrig sib xyaw ua tiav, cov slurry yog lim los ua cov khoom siv lim nrog ntau tshaj 90% zinc cov ntsiab lus. Lub lim ncuav mog qab zib yog tom qab tov los tsim cov plua plinc plua plav slurry rau txheej, nrog cov hlau nplaum ntawm 90%.
Siv:
Zinc Plua Plav feem ntau yog siv nyob rau hauv cov txheej txheem kev lag luam, xws li hauv cov organic thiab inorganic zinc-nplua nuj los tiv thaiv corrosion. Nws tseem siv nyob rau hauv dyes, metallurgy, tshuaj lom neeg, thiab kws tshuaj. Cov txheej txheej ua lag luam rau txog 60% ntawm zinc fow xav tau, ua raws li los ntawm kev lag luam tshuaj (28%) thiab kev lag luam tshuaj).
Kev sib yuav Zinc Plua Plav muaj ntawm ze li kev sib dhos, suav nrog cov qauv zinc plua plav thiab cov dej siab zoo tshaj plaws zinc plua plav. Cov tom kawg muaj cov ntsiab lus ntau dua, cov khoom siv oxerical, thiab cov khoom lag luam me me, ua rau nws muaj kev ua haujlwm siab. Ultra-kev ua kom zoo siab zoo Zinc Plua Plav yog siv dav hauv cov ntawv thov corrosion thiab kev tiv thaiv corrosion, tshwj xeeb tshaj yog siv rau kev tiv thaiv corrosion. Hauv cov tsho tiv no, zinc plua plav nrog cov me me ntawm tsawg dua 28 μm feem ntau siv. High-ense ultra-nplua zinc Plua Plav Cov Khoom Siv, Txhim Kho Txheej Txheem Kev Siv Los Tiv Thaiv, thiab txhim kho cov txheej txheem tiv thaiv kev ua haujlwm, thiab txhim kho cov kev ua tau zoo, muaj kev lag luam dav.
Fleake zas Nws muaj qhov piv txwv siab (30-100), kis zoo heev, npog, thiab tsuas yog siv hauv dacromet txheej (zinc-coquings). Flake Zinc Plua Plav Muaj cov kev pab them zoo dua, kev muaj peev xwm ua tau zoo nkauj, muaj peev xwm hloov pauv hloov, thiab xim hlau thiab nws yog xim hlau zinc hmoov. Hauv dacromet txheej, fig zinc hmoov kis tau tav toj, txhim kho kev sib cuag nrog cov zinc thiab cov hlau substrate thiab ntawm cov ntaub ntawv zinc. Qhov no ua rau txheej txheej Denser, txuas txoj kev kho kom zoo, kho kom zoo thiab cov phuam tuab thiab txhim kho kev tiv thaiv corrosion. Kev tiv thaiv cov txheej txheem corrosion ua nrog flake Zinc Plar Cov tshuaj txau lossis kub-quav av ntau, nrog kev tiv thaiv qis dua, ntsib kev tiv thaiv qis dua.
