Tham txog Qhov laj thawj rau cov xim tsis sib xws ntawm Oxide zaj duab xis ntawm Aluminium Profiles

Muaj peb yam ua tau rau cov xim tsis sib xws ntawm of the elevator oxide zaj duab xis:

(1) Qhov chaw ntawm lub workpiece loj dhau, lub viav vias hauv qhov zawj yog qhov loj heev thaum lub sijhawm ua haujlwm, thiab kev sib cuag, rov ua dua tshiab thiab sib pauv ntawm ntug thiab qhov chaw nruab nrab thiab cov tshuaj sib txawv heev, ua rau cov xim tsis sib xws oxide zaj duab xis. Kev tiv thaiv txoj kev: Lub viav vias ntawm lub workpiece yuav tsum me me thaum lub sij hawm oxidation, thiab kev kho zoo li qub kuj tseem ua tau, tab sis thaum qhov kub ntawm cov tshuaj yog tsawg dhau, daim duab qhia chaw zoo li yuav tshwm sim, uas yog qhov tsis zoo.

(2) Ib feem ntawm aluminium cladding txheej tau puas thaum lub sij hawm ua cov clad elevator qhov chaw thiab raug txiav tawm. Sab nrauv clad aluminium yog aluminium zoo, thiab sab hauv txheej ntawm clad yog lwm yam txhuas. Qhov sib txawv ntawm ob hom txhuas yog loj, yog li nws tshwm sim tom qab oxidation "Zoo vitiligo"-zoo li me ntsis. Qhov tshwm sim no feem ntau tsis to taub los ntawm cov neeg siv khoom, thiab cov neeg tsim khoom yuav tsum ua ntau txoj haujlwm piav qhia vim li cas, thiaj li tsis ua rau muaj kev nkag siab yuam kev.

(3) Cov teeb meem hauv cov txheej txheem kev ua haujlwm: ① Kev kho alkaline etching ntawm lub workpiece tsis tiav, thiab thawj oxide zaj duab xis thiab av tsis raug tshem tawm hauv qee qhov chaw; ② Qhov saum npoo ntawm lub workpiece tseem yog alkaline yam tsis muaj lub teeb rho tawm tam sim tom qab alkali etching; ③ Lub workpiece yog nyob rau hauv cov txheej txheem hloov. tiv tauj nrog cov khoom txawv teb chaws.
