Vim tias tus nqi tooj dag ceev kom nce ntxiv, zinc alloy plating thev naus laus zis tau nce siab ntxiv. Tam sim no, feem ntau ntawm cov xauv lub tog raj kheej tau tso tseg kev siv tooj dag los ua khoom siv, tsis txhob siv cov zinc alloy. Daim ntawv no nthuav qhia lub ntsiab kev paub ntawm zinc alloy.
Firstly, cov yam ntxwv ntawm zinc alloys
1. Qhov ruaj khov ntawm cov yaj yuav tsum tau yog tsis siab. Melting ntawm 385 C tuaj yeem yooj yim tsim los ntawm tuag casting.
2. Lub zog muaj zog ntawm lub tshuab thiab hnav tsis kam ntawm qhov kub.
3. txheej txheem ntawm cov khoom siv
4. Lub luag haujlwm muaj nuj nqi yog muaj zog. Nws tuaj yeem tuag-cam khwb cia txhua yam meej thiab raug cov cuab yeej nrog cov qauv duab thiab nyias ntsa raws li kev xav tau sib txawv. Qhov saum npoo ntawm kev kos yog du thiab txheej txheem.
5. Tsis tas yuav nqus cov hlau hauv yaj thiab tuag casting lag luam, thiab nws tsis yooj yim rau lo.
6. Kev kho tau yooj yim saum npoo av, xws li electroplating, txau, pleev duab thiab lwm yam haujlwm.
