Khoom Paub meej
Zinc alloy muaj cov yam ntxwv ntawm qhov me me crystallization kub ntau, qis melting point, yooj yim sau thiab molding, tsis yooj yim rau looseness thiab pwm sticking, thiab muaj peev xwm mus cuag lub neej ntawm cov tuag-casting pwm.
Zinc alloy tuag-casting
Zinc alloy tuag-casting muaj cov cuab yeej siv siab thiab tuaj yeem siv los tua ntau yam nyuaj thiab nyias-walled castings. Cov castings tuaj yeem raug rau ntau yam kev kho saum npoo, tshwj xeeb tshaj yog muaj cov khoom siv electroplating zoo, thiab muaj kev ua haujlwm zoo hauv chav tsev.
Tom qab zinc alloy tuag-cam khwb cia rau hauv lub casting, nws yuav shrink nyob rau hauv loj, thiab cov alloy muaj feem xyuam rau qhov loj me me. Qhov loj ntawm zinc alloy castings uas tsis muaj tooj liab yog qhov ruaj khov, thiab qhov loj ntawm zinc-aluminium alloy castings tsis hloov ntau.
Tuag-cam khwb cia zinc alloy khoom
Tuag-cam khwb cia zinc alloy yog ib hom engineering alloy, feem ntau muaj zinc, txhuas, tooj liab, magnesium, thiab lwm yam. Cov hauv qab no yog cov khoom siv zinc alloy tuag-cam khwb cia:

- Cov saum toj no yog qee qhov kev tuag-cam khwb cia zinc alloy khoom qauv. Cov qauv sib txawv muaj cov yam ntxwv sib txawv thiab kev siv. Cov khoom tsim nyog tuaj yeem xaiv tau raws li qhov tshwj xeeb daim ntawv thov scenarios. Feem ntau, zinc alloy tuag-cam khwb cia cov ntaub ntawv tuaj yeem siv los tsim ntau yam khoom sib txawv, suav nrog cov khoom siv hluav taws xob, cov khoom siv tsheb, cov khoom siv hauv tsev, cov cuab yeej siv, thiab cov khoom siv tshuab.
Zinc alloy khoom
Kev ua haujlwm ntau ntawm zinc alloy yog nqaim. Thaum qhov kub thiab txias qis dua 0 degree, nws qhov cuam tshuam toughness txo qis, thiab thaum kub siab tshaj 100 degree, cov khoom siv kho tshuab txo qis heev.
Zinc alloy yog nquag mus rau kev laus, thiab cov aging tshwm sim yog tshwm sim los ntawm ntim expansion, lub zog txo, thiab plasticity txo. Qhov laj thawj tseem ceeb yog qhov solubility ntawm impurities xws li txhuas, tin, thiab cadmium hauv zinc tsawg dhau. Yog li ntawd, cov ntsiab lus impurity yuav tsum nruj me ntsis tswj thaum xaiv cov khoom thiab smelting.
Lub luag haujlwm thiab kev cuam tshuam ntawm zinc alloy tuag-casting ntsiab
Ntawm cov zinc alloy Cheebtsam, cov ntsiab lus zoo yog aluminium, tooj liab, thiab magnesium; Cov khoom tsis zoo yog txhuas, cadmium, tin, thiab hlau.
- Lub luag haujlwm ntawm cov ntsiab lus alloy: Aluminium yog lub ntsiab alloying hauv zinc alloy. Nws tuaj yeem txhim kho fluidity ntawm zinc kua, yog li txhim kho nws cov kev ua tau zoo casting. Thaum cov ntsiab lus txhuas yog 5%, eutectic alloy muaj qhov zoo tshaj plaws fluidity, tab sis qhov cuam tshuam lub zog yog tsawg. Aluminium nyob rau hauv thaj tsam ntawm 3.9% mus rau 4.3%, ntawm ib sab, ntxiv dag zog rau cov hlau, zoo refines cov nplej, thiab txhim kho lub zog; ntawm qhov tod tes, nws ua rau cov alloy kom muaj cov khoom zoo dua. Aluminium muaj qhov cuam tshuam ntawm cov nplej ua kom zoo dua qub thiab cov kev daws teeb meem muaj zog, uas tuaj yeem txo qhov ceev ntawm cov tshuaj tiv thaiv ntawm zinc thiab hlau. Thaum cov ntsiab lus txhuas ntau tshaj 4.3%, cov hlau ua nkig thiab castings nyuaj rau txheej txheem. Thaum cov ntsiab lus txhuas tsawg dua 3.9%, cov phab ntsa nyias nyias yog qhov nyuaj rau kev tsim thiab tuaj yeem tawg thaum txias tom qab casting.
- Kev ua haujlwm ntawm magnesium yog txhawm rau txo qis kev sib txhuam, ua kom zoo dua cov qauv ntawm zinc alloy, txhim kho cov khoom tiv thaiv hnav ntawm zinc alloy, thiab ua kom lub zog thiab
- tawv. Nws feem ntau tswj tau nyob rau hauv thaj tsam ntawm {{0}} 03% ~ 0.08%. Yog tias nws siab tshaj 0.08%, nws yuav yooj yim ua rau thermal brittleness, thermal cracking, thiab txo fluidity.
- Copper tuaj yeem txhim kho lub zog, hardness, hnav tsis kam, thiab corrosion kuj ntawm alloy. Thaum cov ntsiab lus tooj liab ntau dua 1.25%, qhov loj me ntawm qhov casting tsis ruaj khov thiab cov fluidity ntawm alloy yog txo.
- Lead yog nyob rau hauv daim ntawv ntawm zoo kheej kheej hais los yog nto zaj duab xis faib ntawm grain ciam teb thiab dendrites, ua rau intergranular corrosion.
- Tin thiab zinc tsim ib qho qis melting point (198 degree) eutectic, ua rau intergranular corrosion los txo toughness thiab ua rau thermal embrittlement.
- Cadmium muaj nyob rau hauv ib qho kev daws teeb meem. Ua rau thermal brittleness, txo corrosion kuj thiab fluidity, thiab ua rau intergranular corrosion.
- Hlau thiab zinc daim ntawv sib txuas, tsim cov ntsiab lus nyuaj hauv kev tuag castings, cuam tshuam rau kev ua thiab electroplating polishing. Tsis tas li ntawd, hlau kuj reacts nrog txhuas los tsim FeAl thiab dross, ua rau cov ntsiab lus txhuas ntawm cov casting txo.
Cov teeb meem ntawm impurity ntsiab lead, tin, thiab cadmium
Lead, tin, thiab cadmium cov ntsiab lus yog impurity ntsiab nyob rau hauv zinc alloys thiab yuav tsum tau tswj nyob rau hauv cov qauv ({{0}}.004%). Yog tias cov hmoov txhuas thiab cov tin ntau tshaj tus qauv (0.007%), nws yuav tsis muaj kev cuam tshuam rau cov khoom thiab ua rau plating blistering nyob rau lub sijhawm luv luv. Txawm li cas los xij, cov khoom xa rov qab los ntawm electroplating yuav maj mam hlwv tom qab khaws cia rau lub sijhawm. Yog hais tias cov hlau lead thiab tin ntsiab lus tshaj tus qauv los ntawm ntau tshaj kaum los yog kaum ob lub sij hawm, cov pressed castings yuav kub tawg, tawg, thiab blackened. Qhov saum npoo yuav raug pitted tom qab polishing thiab intergranular corrosion yuav tshwm sim sab hauv, ua rau blistering tom qab electroplating.
Kev xaiv ntawm zinc alloy yog ib feem tseem ceeb ntawm kev ua cov khoom siv electroplated. Alloy electroplating khoom yog kiag li tsis pub tshaj tus qauv ntawm txhuas thiab tin. Nws yog ib qho tsim nyog los tswj cov khoom siv nozzle rov qab mus rau qhov cub, thiab cov khoom tsis huv ntawm cov hlau lead, tin, thiab cadmium coj mus rau hauv cov khoom pov tseg electroplating.
