Zinc alloy
Zinc alloy muaj qhov qis melting point, zoo fluidity, thiab yooj yim fusion vuam.
Cov txheej txheem tsim khoom tuaj yeem muab faib ua zinc alloy thiab deformation zinc alloy. Casting zinc alloy muaj zoo fluidity thiab corrosion kuj, haum rau tuag casting instrumentS, tsheb qhov chaw shells, thiab hais txog. Deformed zinc alloy muaj zoo plasticity thiab ductility. Nws yog tsuas yog siv rau roj teeb plhaub, luam ntawv boards, ru tsev boards, thiab cov khoom siv niaj hnub.
Cov txiaj ntsig ntawm cam khwb cia hlau yog ntau dua li ntawm deformed alloy. Rau FMCG cov khoom siv, cov hlau deformed tsis tshua siv. Yog li ntawd, cov nram qab no tsuas yog rau tuag-cam khwb cia zinc alloy. Qhov ceev ntawm zinc alloy yog 6.3 ~ 6.7g / cm, lub zog tensile yog 28{11}} ~ 440MPa, lub melting point yog tsawg, melting ntawm 385 degree, yooj yim rau tuag casting. Zinc alloy muaj qhov loj tshaj plaws thiab qhov zoo tshaj plaws fluidity ntawm plaub alloys piav nyob rau hauv daim ntawv no. Nws muaj kev ua haujlwm zoo casting thiab tuaj yeem tuag-casting complex thiab nyias-walled precision qhov chaw, thiab nto ntawm lub casting yog du. Lub thinnest phab ntsa thickness ntawm zinc alloy tuag-casting tsuas yog 0.4 hli. Zinc alloy muaj lub zog zoo ntawm chav tsev kub. Nws yuav tsum tau muab sau tseg tias zinc alloy yuav tsum tsis txhob siv nyob rau hauv siab thiab tsis kub (qis dua 0 degree) ua hauj lwm ib puag ncig, zinc alloy muaj zoo mechanical zog ntawm chav tsev kub. Txawm li cas los xij, lub zog tensile thiab kev cuam tshuam kev ua haujlwm tau txo qis ntawm qhov kub thiab txias. Zinc alloy muaj qhov tsis zoo corrosion kuj. Thaum lub impurity ntsiab ntawm txhuas, cadmium thiab tin nyob rau hauv lub alloy tshaj tus qauv, casting aging thiab deformation yuav tshwm sim. Zinc alloy tuag casting muaj cov nyhuv aging thiab aging phenomenon, uas yog, lub zog poob lawm tom qab ib tug ntev lub sij hawm thiab ua nkig. Qhov no yog vim li cas thiaj xaiv kom deb li deb tau thaum kho kom zoo nkauj txhua tus, tsis txhob xaiv zinc alloy. Muaj coob tus neeg tso dag tias thaum hloov zinc alloy faucet, nkig tawg feem ntau tshwm sim, ua rau cov xov ib feem ntawm tus kais dej nyob hauv cov yeeb nkab dej tsis tuaj yeem tawm.
Tam sim no, cov txheej txheem ntawm castings tau muab faib ua ob pawg: ZAMAK alloy thiab ZA series alloy. ZAMAK alloys yog ZAMAK 2, ZAMAK 3, ZAMAK5 thiab ZAMAK 7. ZA series suav nrog ZA-8, ZA-12, ZA{10}} thiab ZA-35. Za-8 feem ntau yog siv rau kub chamber tuag casting, thaum ZA-12 thiab ZA{14}} tsuas yog siv tau rau chav txias txias tuag casting vim lawv cov kev xav tau tshwj xeeb melted. Za-35 feem ntau yog siv rau lub ntiajteb txawj nqus castings. ZAMAK alloy tau tsim ua ntej tshaj ZA series alloy, feem ntau yog siv rau siab casting. Feem ntau siv yog zinc alloy no. 3.
ZAMAK 2: siv rau cov khoom siv kho tshuab nrog cov kev xav tau tshwj xeeb rau cov khoom siv kho tshuab, cov kev xav tau siab rau hardness, zoo hnav tsis kam thiab cov kev cai dav dav rau qhov raug qhov tseeb.
ZAMAK 3: Zoo fluidity thiab mechanical zog. Siv los ua cov khoom siv hluav taws xob tsis tshua muaj zog, xws li cov khoom ua si, teeb thiab teeb ci, kho kom zoo nkauj, thiab qee qhov hluav taws xob.
ZAMAK 5: Zoo fluidity thiab zoo mechanical zog. Siv rau castings nrog tej yam yuav tsum tau ntawm txhua yam muaj zog, xws li tsheb qhov chaw, electromechanical qhov chaw, mechanical qhov chaw, thiab hluav taws xob Cheebtsam.
ZA8: Nws muaj kev cuam tshuam zoo zog thiab qhov ruaj khov, tab sis tsis muaj dej txaus. Nws yog tsim rau tuag casting workpieces nrog me me, siab precision thiab siab mechanical zog, xws li hluav taws xob qhov chaw.
Superloy: zoo tshaj plaws fluidity, haum rau tuag casting nyias-walled, loj loj, siab precision, complex zoo workpieces, xws li hluav taws xob Cheebtsam thiab lawv cov thawv.
