Vim li cas thiaj yuav tsum aluminium profile cua sov dab dej yuav tsum anodized?

Dab tsi yog oxidation ntawm aluminium profile cua sov dab dej?

Aluminium profile heat sink oxidation kev kho yog hais txog kev kho deg anodization ntawm aluminium profile cua sov dab dej.

 

Kev kho deg anodizing ntawm aluminium profile cua sov dab dej yog siv dav siv thev naus laus zis ntawm aluminium profile cua sov dab dej. Qhov kev tiv thaiv corrosion thiab abrasive tsis kam ua haujlwm tau zoo dua qub, tsis yog tsuas yog qhov zoo ntawm kev siv, tab sis kuj zoo nkauj zoo nkauj.

Puas yog aluminium profile cua sov dab dej yuav tsum tau anodized? Vim li cas thiaj yuav tsum aluminium profile cua sov dab dej yuav tsum anodized?

Qhov tshwm sim hais tias qhov saum npoo ntawm cov hlau reacts chemically los yog electrochemically nrog ib puag ncig nruab nrab, yog li ua rau cov hlau puas, feem ntau hu ua corrosion ntawm cov hlau. Corrosion ntawm hlau ua rau peb poob loj heev txhua xyoo. Ib txoj hauv kev los tiv thaiv kev xeb hlau yog tsim cov oxide zaj duab xis tiv thaiv txheej ntawm cov hlau nto. Ntau cov hlau muaj cov yeeb yaj kiab oxide ntuj, tab sis feem ntau ntawm lawv tsis tuaj yeem ua lub luag haujlwm ntawm cov txheej txheem tiv thaiv.
Aluminium profile kub dab dej siv aluminium alloy ua cov khoom siv. Aluminium thiab Aluminoy Alloy muaj qhov zoo ntawm qhov ceev, muaj zog, zoo hluav taws xob thiab thermal ua haujlwm, yooj yim moulding, thiab tsis muaj qhov kub thiab txias. Nws yog ib qho khoom siv hlau uas muaj cov khoom zoo heev.

Tam sim no, txhuas profile tau siv dav hauv kev lag luam aerospace, cov khoom siv hauv tsev, tsheb, khoom siv hluav taws xob thiab lwm yam haujlwm. Aluminium muaj cov tshuaj muaj zog tshwj xeeb rau cov pa oxygen, thiab nws qhov chaw yog ib txwm npog los ntawm txheej pob tshab oxide zaj duab xis nyob rau hauv qhov chaw, tab sis lub ntuj aluminium oxide zaj duab xis yog nyias nyias, tsuas yog 4x10-3-5x10-3 um, thiab muaj qhov loj npaum li cas, tsis tshua muaj zog txhua yam, tsis kam thiab hnav tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev tiv thaiv corrosion.

 

Noj cov tshav kub ua kom tawg dab dej ua piv txwv, cov qauv siv hluav taws xob zoo nkauj rau cov xim zoo nkauj rau ntawm txhuas lossis txhuas kom tuab tuaj yeem ncav cuag ob caug ntawm microns, uas tuaj yeem txhim kho corrosion kuj ntawm txhuas. Cov txheej txheem electrochemical ntawm oxidizing saum npoo ntawm txhuas yog hu ua anodizing ntawm txhuas.

Tsis tas li ntawd, vim tias cov yeeb yaj kiab oxide tsim muaj cov pores zoo ib yam, nws kuj tuaj yeem ua rau cov organic dyes, thiab cov xim yog ruaj khov tom qab sealing, uas ua rau daim ntawv thov ntawm txhuas ntau dua.

Yog li ntawd, aluminium profile heat sink feem ntau yuav tsum tau oxidized, tab sis nws tsuas yog nyob ntawm qhov xav tau tiag tiag ntawm cov neeg siv khoom.
