Txoj kev kho deg ntawm aluminium alloy tuag casting

Kev kho saum npoo ntawm aluminium alloy tuag castings tuaj yeem muab faib ua ua ntej -kev kho thiab tom qab- kho. Kev kho ua ntej -kev kho yog tshem tawm cov nplai thiab roj ntawm qhov chaw, ua kom cov adhesion ntawm ncej- kev kho mob, thiab txhim kho qhov tsos. Feem ntau saum npoo ua ntej- kev kho ntawm aluminium alloy tuag castings suav nrog kev tua blasting, xuab zeb blasting, thiab phosphating, thiab tom qab- kev kho mob feem ntau siv tshuaj tsuag, oxidation, electroplating, thiab electrophoresis. Vim yog vim li cas tus nqi, lwm txoj kev kho saum npoo tsuas yog tsim rau cov khoom siv tshwj xeeb.

Aluminium Alloy Die Casting Surface Pre-Txoj kev kho

1. Aluminium alloy tuag-casting phau ntawv ua:

Xws li scrapers, hlau txhuam los yog sib tsoo log. Cov xeb thiab nplai ntawm qhov chaw ua haujlwm -thooj tuaj yeem raug tshem tawm ntawm tes, tab sis kev ua haujlwm ntawm tes yog kev ua haujlwm hnyav-.

Lub zog dynamic yog siab, qhov kev ua tau zoo ntawm cov khoom qis, qhov zoo yog qhov tsis zoo, thiab kev tu tsis huv.

2. Aluminium Alloy Tuag Casting Tshuaj Kho Mob:

Nws tsuas yog siv cov kua qaub-puag cov tshuaj rau cov tshuaj tiv thaiv oxide thiab roj rau ntawm qhov chaw ua haujlwm, kom nws tuaj yeem yaj hauv cov kua qaub lossis alkali daws kom tshem tawm cov xeb thiab roj ntawm qhov chaw ua haujlwm, thiab tom qab ntawd siv cov txhuam txhuam ua los ntawm cov nylon lossis stainless hlau xaim (Steel txhuam cov menyuam ua los ntawm cov kua qaub{{1} hauv paus tov) ntxuav tau. Kev kho tshuaj yog tsim nyog rau kev ntxuav cov phaj nyias.

3. Kev kho mob ntawm aluminium alloy tuag casting:

Nrog rau txoj kev txhuam hlau, kev siv tshuab polishing thiab kev txhaj tshuaj blasting.

a. Hlau hlau txhuam cov menyuam polishing txoj kev, uas yog, cov txhuam cov menyuam yog tsav los ntawm lub cev muaj zog, thiab cov txhuam cov menyuam tig ntawm qhov kev kub ceev ntawm qhov chaw sab sauv thiab sab qis ntawm cov sawb nyob rau hauv cov kev taw qhia rov qab mus rau cov kev taw qhia ntawm cov dov daim kom tshem tawm cov nplai. Cov nplai txhuam txhuam yog ntxuav tawm los ntawm kev kaw cov dej txias txias dej ntws tawm.

b. Mechanical polishing yog ib txoj kev polishing uas tshem tawm cov khoom seem tom qab polishing thiab tau txais ib tug du nto los ntawm kev txiav thiab yas deformation ntawm cov khoom nto. Feem ntau, nws yog roj pob zeb, wool log, sandpaper, thiab lwm yam. Ob leeg yog siv, thiab phau ntawv ua haujlwm yog txoj kev tseem ceeb. Rau qhov tshwj xeeb xws li qhov chaw ntawm lub cev tig, cov cuab yeej pabcuam xws li turntables tuaj yeem siv. Rau qhov yuav tsum tau ua kom zoo, ultra- polishing tuaj yeem siv tau. Super abrasive polishing yog cov cuab yeej tshwj xeeb abrasive, uas yog nias rau ntawm qhov ua tiav ntawm qhov chaw ua haujlwm -thooj hauv cov kua abrasive polishing thiab tig ntawm kev kub ceev.
