Peb txhua tus paub qhov ntawdindustrial aluminium profilesyog cov khoom siv extrusion alloy. Kev ua haujlwm tsis raug ntawm ib kauj ruam hauv kev tsim khoom thiab kev ua haujlwm tuaj yeem ua rau cov khoom puas tsuaj thiab qhov tsis xws luag ntawm qhov profile. Cov xim saum npoo ntawm ib txwm aluminium profiles yuav tsum yog silvery dawb. Ntawm no kuv yuav tham luv luv txog cov laj thawj ntawm qhov tshwm sim daj uas feem ntau tshwm sim rau ntawm qhov profile ntxiv rau roughness thiab dullness.

Nyiaj dawb aluminium profile

Muaj ob lub laj thawj tseem ceeb rau yellowing ntawm qhov chaw ntawm qhov profile. Ib qho yog txoj kev ua kom txias tsis zoo thaum lub sij hawm extrusion txheej txheem ntawm qhov profile, thiab lwm yam yog qhov kev kho deg tsis zoo ntawm qhov profile. Kev tsom xam tshwj xeeb yog raws li hauv qab no:

1. Cov profile yuav tsum tau txias tom qab extruded los ntawm cov tuag, thiaj li yuav txhim kho cov neeg kho tshuab thiab lub cev ntawm cov khoom. Coolant yuav tsum tau siv rau hauv cov txheej txheem txias, thiab cov khoom sib txawv muaj qhov sib txawv ntawm cov dej txias. Cov feem ntau yog dej los yog roj-raws li coolants. Yog tias cov dej siv los ua kom txias lossis qhov feem ntawm cov tooj liab hauv lub coolant loj heev, nws yog ib qho yooj yim ua rau lub ntsej muag ntawm qhov profile tig daj. Qhov laj thawj yog vim li cas aluminium yog cov khoom siv tshuaj lom neeg hlau, thiab nws yog qhov ua rau muaj tshuaj lom neeg thaum nws nkag mus rau hauv cov ntaub ntawv hauv huab cua thiab dej.

2. Qhov saum npoo ntawm kev lag luam aluminium profiles yog txuas nrog oxide zaj duab xis, uas tuaj yeem ua rau kom muaj kev tiv thaiv corrosion thiab nto aesthetics ntawm cov profiles. Ua ntej kev kho deg ntawm qhov profile, extruded profile yuav tsum tau ntxuav kom tshem tawm cov roj ntawm qhov chaw. Yog tias qhov chaw ntawm qhov profile tsis raug ntxuav kom zoo, nws yog ib qho yooj yim ua rau cov oxide zaj duab xis yuav nyuaj rau xim hauv cov txheej txheem oxidation tom ntej, lossis cov xim yuav tsis sib xws, thiab yellowing yuav tshwm sim.
