Sababta oo ah sunta ah ee chromium chromium-ka hexavalen ee jinc-chrc-chromium-ka, wadamada adduunka si tartiib tartiib ah ayey u joojinayaan wax soo saarka iyo isticmaalka xirmooyinka chromium-ka. Teknolojiyadda 'chromium-aluminium' ee 'zinc-aluminium' waa nooc cusub oo ah "cagaaran" tikniyoolajiyad daaweyn dusha sare ah. Waa dabool sheeko zinc-aluminium oo si fiican u fuliya oo buuxiya shuruudaha ilaalinta deegaanka, taasoo ka dhigeysa isbeddel lagu beddelo dharkaaga zinc-chromium. Soosaarka koofiyadaha 'chcimium-aluminium' waxay u baahan tahay waxyaabo kala duwan oo ceyriin ah, oo leh budada zinc ee zinc ah oo ah midka ugu muhiimsan.
Zinc | Biro-bir-cawlan oo leh luster metallic ah oo ku yaal iskutallaabta-qaybta, kaas oo ka sameysan lakabka cufan ee filimka carbonate ee ku yaal dusha sare ee heerkulka qolka, bixinta saameynta kahortaga. Barta dhalaalaysa zinc waa 419.8 ° C, oo cufnaanta waa 701 g / m³. Heerkulka qolka, waa wax aad u burbursan, jilcisa 100-150 ° C oo mar labaad noqo heerkulka ka sarreeya 200 ° C. Zinc waxay leedahay sedex dowladood oo crystallonene: α, β, iyo γ, iyo γ, oo leh heerkulka isbedelka ee 170 ° C iyo 330 ° C. Wadahadalka korantada ee zinc waa 27.8% taas oo ah lacagta, iyo horumarka ay ku jirtaa ayaa ah 24.3% oo ah lacagtaas.
Noocyada boodhka zinc
Sida ku xusan qaabka iyo codsiga, budada zinc waxaa lagu tilmaami karaa budo zerguik zincing, budada zinc-ka, iyo budada zinc-batteriga. Qaababka wax soo saarka ee kala duwan ayaa soo saari kara budada zinc ee qaabab kala duwan, walxaha, iyo codsiyada.
Inta badan midabka macdanta metallic waxay isticmaalaan boodh bir ah oo bir ah. Booska zinc ee zinc waxaa loo sameeyay jaakad ka dibna codsatay. Qeybku wuxuu ka samaysan yahay filim ku saabsan dusha sare ee substrate, halkaas oo boodhka biraha ah ee biraha ah ay ku dhegan tahay lakabyo isbarbar dhiga dusha sare, abuurista saameyn gaashaan-galiya. Qaab dhismeedka diyaaradda laba-geesoodka ah ee u gaarka ah, boodhka zinc zinc waxay soo bandhigtaa caymis wanaagsan, adhesion, oo milicsanaanta, iyo saamiga weyn ee weelka ah (50-200).
Guryaha indhaha | Budadaha macdanta ah badankood waxay leeyihiin guryo indhaha ah oo wanaagsan, oo ah mid ka mid ah kartida iftiinka iftiinka. Tusaale ahaan, jaakadaha zinc-aluminiumka ayaa soo bandhiga saameynta lunta-ka-baxa ee macdanta.
Difaaca guryaha | Marka boodhka zinc ee zinc loo sameeyo jaakad oo lagu dabaqayo si loo sameeyo filim, boodhka biraha ah ee biraha ah ayaa ku habboon lakabyada isbarbar dhiga dusha sare, abuurista saameyn gaashaan-galeenka.
Guryaha saboolka ah | Astaamo kale oo muhiim ah oo ah boodhka zinc ee zinc waa awood ay tahay in lagu sabbo, taasoo u oggolaanaysa inay ku sii jirto dusha sare ee qalabka side.
Garsooraha Gaarka ah | Qaab dhismeedka diyaaradda laba-geesood ee laba-geesoodka ah, zinc zinc waxay leedahay caymis aad u wanaagsan, adhesion, waxyeelo weyn, iyo kacsanaan, oo ay weheliso iska caabbinta xasaasiga ah.
