Chemical formula: Zn
Molecular uremu: 65.38
Zvivakwa:
Zinc isimbi ine chena-chena ine hexagonal yepedyo-yakazara crystal chimiro. Iyo ine inonyungudika yenyaya ye1199.58 ° C, iyo inovhara ye 907 ° C, kuomarara kwe2,5, kupokana kwemagetsi kwe0,02 · · m · mmɨ / m, uye density of 7.14 g / cm³.
Zinc guruva pigment inouya mune maviri zvikamu zvimisikidzo: spherical uye flake-like. Firke-kunge guruva reZinc rine simba rakakura rekuvhara.
Makemikari, guruva reZinc rinofanira kuita chaizvo. Mumamiriro ezvinhu akajairwa emukati, anoumba mutete, dense denderedzwa reZinc carbonate pamusoro payo, iyo inotadzisa imwe oxidation, ichiita kuti iite zvakanyanya-zvinopesana mumhepo. Nekudaro, hazvisi kuramba kuora muacdic kana alkaline munyu. Inopaza muAcids Acids, zvigadziko, uye acetic acid asi haina kujekesa mumvura.
Zinc guruva rinopisa nemurazvo wakajeka wakachena mune yakachena okisijeni asi yakaoma kuendesa mumhepo yakajairika, saka haina kuiswa seyakaomarara. Munzvimbo dzakajairika, zinc guruva rinobata nemunyoro kana mvura yekugadzira hydrogen gasi, asi huwandu hwe hydrogen kugadzirwa kwehydrogen zvakanonoka, kushoma pane 1 l / (kg ·). Naizvozvo, guruva re zinc harina kujekeswa sechinhu chinoburitsa magasi anopisa paunonangana nemvura. Nekudaro, nekuda kwekuchengetedza kwakachengeteka uye kwekufambisa, zvinokurudzirwa kuti ubate sekirasi 4.3 ine njodzi zvinhu (zvinhu zvine njodzi kana zvakanyorova). Parizvino, mirairo yekuchengetedza uye yekufambisa yeZinc Powder inosiyana munzvimbo dzakasiyana muChina, pamwe nekuwedzera kushaya simba uye vamwe vanonyanya kuoma.
Zinc guruva rinogona kuputika mumhepo, maitiro anosanganisira gasi-phase conustion. Semuenzaniso, Micron-Sized zinc guruva ine yakakwana yekubvisa nguva yekurumidza nguva ye 180 ms, neyekuputika muganho we1500-2000 G / M³. Pakusangana kwe5000 g / m³, inosvika pakakwirira kuputika kumanikidzwa, yakanyanya kuputika indekwana index, iyo iri 0.481 mpa, 46.67 MPA / s, zvichiteerana. Iko kuputika kwenjodzi nzengozi yeiyo micron-sizoni zinc poda inogadziriswa seSt1, inoratidza njodzi yakaderera inoputika.
Maitiro Ekugadzira:
1. Upstream-zinc ore smelting:
China ine zvakawanda zinc ore zviwanikwa, accounting kweanenge makumi maviri muzana ematunhu epasi rose, yechipiri chete kuAustralia. China zvakare zvakare mugadziri mukuru we zinc ore, inopa pamusoro pechikamu chimwe chete muzvitatu chekugadzirwa kwepasirese, chinzvimbo chekutanga pasi rese. Maitiro ekunyepedzera anosanganisira kunatsa zinc ore kuti awane zinc sulfide sulfide, iyo yakabva yaderedzwa kusvika kuZinc yakachena kuburikidza neHyrometallurgical kana hydrometallurgical process, zvichikonzera mitsva yeZinc.
Muna 2022, zinc's zinc ingot kugadzirwa kusvika pamatani makumi matanhatu nemaviri emamiriyoni. Mutengo weZinc Ingots Kupedzisira inosarudza mutengo wechiSperical zinc poda, iyo inogona kufungidzirwa ku 1.15-1.2 nguva mutengo weZinc ingots ingots.
2. Zinc guruva-atomization nzira: **
Yakanyanya-Kuchena (99.5%) Zinc Ingots inoiswa kusvika 400-600 ° C mune revhubertory kana rotary choto kusvikira yakanyungudutswa. Iyo yakanyungudika zinc inobva yaendeswa kune inowanzoitika uye atomized pasi pemamiriro ekunze uye akaomeswa mamiriro, nemhepo yakamanikidzwa pakumanikidzwa kwe0.3-0.6 mpa. Iyo Atomized zinc poda inounganidzwa muguruva muunganidzi uye yakabva yadarika neyakawedzera-denging yakavanzika yekuzviparadzanisa muzvimiro zvakasiyana pamberi.
3. Zinc guruva-bhora yekugaya nzira: **
Iyi nzira inogona kuve yakaoma kana yakanyorova, inogadzira yakaoma furuva zinc guruva kana paste-senge flake zinc guruva. Semuenzaniso, bhora rebwe rinogona kuburitsa paste-kunge flake zinc guruva slurry. Atomized zinc poda yakasanganiswa nealiphatic hydrocarbon sol sol soles uye chidiki chidiki che lubricant mune bhora chigayo. Kamwe chete iyo yaunoda fiteness uye flake chimiro chinowanikwa, iyo slurry yakadzvanywa kuti iite chikero chefirita neinopfuura 90% zinc zvemukati. Keke yefaini inobva yasanganiswa kuti igadzire zinc guruva slurry yejasi, ine simbi yezvinyorwa zvinopfuura 90%.
Inoshandisa:
Ginc guruva rinonyanya kushandiswa mumakonzo ejasi, senge mu organic uye inorganic zinc-pfuma anti-corrosion colatings. Izvo zvinoshandiswawo mumadhadha, metallurgy, makemikari, uye mishonga yemishonga. Iwo maCoatings indasitiri maakaundi kweanenge 60% yeZinc Powder Fincess, inoteverwa nemakemikari indasitiri (28%) uye indasitiri yemishonga (4%).
Spherical zinc guruva rine zvimedu zvechinguvana, kusanganisira standard zinc guruva uye Ultra-yakanaka-yechiitiko zinc guruva. Iyo yekupedzisira ine yakakwira zinc zvemukati, zvakasvibiswa zvakadzika, zvakanyatsoita spherical zvimedu, chiitiko chakanaka, nzvimbo diki yekuparadzira, uye kuparadzaniswa kwakaringana, nekupararira kwakanaka, kuzviita chigadzirwa chakakwirira. Ultra-yakanaka-yechiitiko zinc guruva rinoshandiswa zvakanyanya mumatombo uye anti-corrosion application, kunyanya muZinc-pfuma primers kana yakananga kuAnti-Corrosion COatings. Mujasi, guruva zinc nechikamu chetsvina chisingasviki 28 μm chinowanzoshandiswa. Yakakwira-perform Ultra-yakanaka zinc guruva inochengetedza zviwanikwa, inovandudza kushanda zvakanaka, uye inosimbisa kubata kweanti-corrostion perinoita, kupa yakafara tarisiro yemusika.
Flake zinc guruva ine flake-seyakafanana nechimiro uye inogadzirwa nebhora yekugaya kana yemuviri vapor deposition (PVD). Iyo ine chikamu chakakwirira chiyero (30-100), kufukidza, nekuvhara, uye zvinonyanya kushandiswa muDacromet Coatings (Zinc-Aluminium Coatings). Flake zinc guruva inopa zvirinani kufukidzwa, kugona kugona, kugona kwekudzivirira, kugona kwekuchengetera, uye masimbi ekusimbisa achienzanisa nehure re zinc. MuDcromet Coatings, Flake Ginc guruva rakatambanudzwa Izvi zvinoguma zvaitika mune denser coating, yakawedzera nzira dzekudyidzana, yakawedzera zinc kudhinda uye kuunganidzira, uye kuvandudza midziyo yekuvandudza uye anti-corrosion zvivakwa. Mabhonzo eAnti-Corrostion akagadzirwa neFlake Ginc Gurumbha Anoratidzira zvakanyanya munyu Pfupi pane magetsi ekupaza kana kuti anopisa-madhiri ekusvibisa, kusanganisa zvinodiwa zvedziviriro zvemunharaunda.
