Vim li cas thiaj yog qhov saum npoo ntawm txhuas alloy tuag casting qhov chaw dub?

Aluminium Alloy Tuag-Casting Qhov Chawtau siv dav hauv ntau yam kev lag luam vim lawv lub cev qaim, lub zog siab, thiab cov zoo corrosion tsis kam. Txawm li cas los xij, qee zaum qhov saum npoo ntawmAluminium Tuag-Casting AccessoriesYuav tuaj yeem tig xim dub, uas yuav ua rau muaj kev txhawj xeeb thiab tsa cov lus nug txog qhov zoo ntawm cov khoom.

Lub ntsiab tseem ceeb tom qab dubening ntawmTxhuas Alloy Cashotsyog qhov tsim ntawm ib txheej oxide nyob rau saum npoo ntawm seem. Qhov oxide txheej no yog tsim vim muaj cov tshuaj tiv thaiv ntawm txhuas nrog oxygen hauv huab cua. Oxide txheej feem ntau yog ib txheej nyias ntawm txhuas oxide uas muab qee qhov kev tiv thaiv rau cov hlau hauv qab tiv thaiv corrosion. Txawm li cas los xij, qee kis, txheej Oxide yuav dhau los ua thicker thiab tig dub, uas tuaj yeem cuam tshuam rau kev ua kom zoo nkauj ntawm cov ntu.

Lub blackening ntawmAluminium Tuag-Casting Qhov Chawtuaj yeem nrawm los ntawm ntau yam, xws li raug rau cov av noo siab, kub, lossis cov tshuaj hnyav. Cov xwm txheej no tuaj yeem ua rau oxide txheej los txhim kho kom sai thiab kuj tseem yuav coj mus rau lwm tus sib txuas, xws li txhuas hydroxide.

Txawm hais tias muaj blackening ntawm txhuas alloy tuag-casting qhov chaw, nws tsis cuam tshuam rau cov khoom siv tshuab ntawm ntu ntawm ntu. Qhov tseeb, lub xub ntiag ntawm cov oxide txheej yuav muab ntxiv corrosion ntxiv ua rau cov ntu. Ntxiv mus, muaj ntau txoj hauv kev los tshem tawm cov blackening los ntawm saum npoo ntawm ntu, xws li sandblasting lossis tshuaj ntxuav tes.

Yog li ntawd, nws yog ib qho tseem ceeb kom nkag siab tias blackening ntawm txhuas alloy tuag-casting qhov chaw yog muaj peev xwm tshwm sim vim cov tshuaj tiv thaiv ntawm cov pa. Nws yuav tsum tsis txhob noj ua daim paib ntawm cov khoom lag luam zoo lossis cov khoom tsis zoo. Nrog rau kev tuav zoo thiab kev txij nkawm, tuaj yeem txo qis lossis tshem tawm tag nrho lossis tshem tawm tag nrho, thiab cov seem tseem tuaj yeem muab kev txhim khu kev qha thiab ua haujlwm pabcuam.
