Zinc Plua Av

Vim yog cov tshuaj lom ntawm hexavalent chromium hauv Zinc-Chromium txheej, cov teb chaws thoob plaws lub ntiaj teb tau tsim thiab siv cov chromium-muaj txheej txheej. Lub chromium-Dawb Zinc-Aluminium txheej thev naus laus zis yog hom tshiab ntawm "ntsuab" cov thev naus laus zis deg. Nws yog phau ntawv qhia tshiab zinc-txhuas uas ua tau zoo thiab ua tau raws li kev tiv thaiv ib puag ncig, ua rau nws los hloov zinc-chromium txheej. Zeem zus ntawm cov chromium-dawb zinc-txhuas txheej yuav tsum muaj ntau cov khoom siv raw, nrog flake zinc hmoov yog qhov tseem ceeb tshaj plaws.

Zinc | Ib qho nyiaj-grey hlau nrog nws yog xim hlau lus ntawm cov ntoo khaub ncaws, uas ua rau cov yeeb yaj kiab uas zawv zawg ntawm cov duab zaj yeeb yaj kiab, muab cov yeeb yaj kiab sov, muab cov teebmeem kev tiv thaiv chav sov, muab cov teebmeem tiv thaiv chav sov, muab cov kev tiv thaiv. Lub ntsiab lus melting ntawm zinc yog 419.8 ° C, thiab nws qhov ntom ntom yog 701 g / m³. Nyob rau hauv chav tsev kub, nws yog qhov loj me, softening ntawm 100-150 ° C thiab ua braintle dua ntawm qhov kub tshaj 200 ° C. Zinc muaj peb lub xeev crystalline: α, β, thiab γ, nrog kev hloov pauv kub ntawm 170 ° C. Qhov hluav taws xob cuam tshuam ntawm Zinc yog 27.8% ntawm nyiaj, thiab nws thermal conductivity yog 24.3% ntawm nyiaj.

Cov Hom Zin Dust

Raws li cov duab thiab daim ntawv thov, zinc categorized rau hauv spherical zinc hmoov, flake zinc f hmoov, thiab roj teeb-qib zinc hmoov. Cov txheej txheem ntau lawm tuaj yeem ua rau cov hmoov cua zinc ntawm ntau yam duab, kev sib xyaw, thiab cov ntawv thov.

Feem ntau yog xim hlau pigments siv cov hmoov av sib xyaw. Fleake zinc hmoov av yog tsim rau hauv cov txheej txheem thiab tom qab ntawd thov. Cov txheej txheej txheej ua ib zaj duab xis nyob rau sab saum npoo av, qhov chaw nplaim taws qhov chaw nyob rau hauv cov txheej txheem sib dhos nrog cov txheej txheem tiv thaiv kab, tsim cov ntaub thaiv npog. Vim nws qhov tshwj xeeb ob-seem phiaj xwm qauv, flake zinc Plua Plav Cov Qauv Ua Kom Zoo Kev Tiv Thaiv Zoo, Adhesion, thiab ib qho kev sib piv loj (50-200).

Qhov chaw kho qhov muag | Feem ntau cov txiv neej muaj hmoov muaj cov khoom siv kho tshiab, ib qho yog lub teeb pom kev zoo. Piv txwv li, zinc-txhuas txheej ua pov thawj pom cov metallic cov nyhuv nyhuv.

Kev thaiv cov khoom | Thaum flinc hmoov av yog tsim rau cov txheej txheem thiab ua ntawv thov ua ib zaj yeeb yaj kiab, cov hmoov nplej nrog cov txheej txheem sib dhos nrog cov khoom sib dhos.

Nto Floating cov khoom | Lwm qhov tseem ceeb ntawm flake Zinc Pluard yog nws lub peev xwm los ntab, cia nws nyob twj ywm ntawm cov khoom muaj cov khoom muaj.

Cov Khoom Tshwj Xeeb | Vim nws qhov tshwj xeeb ob kab npog, flake zinc dist muaj cov teebmeem zoo heev, cov tshuaj nplaum, nrog rau cov kev tiv thaiv corrosion.
