Aluminium Veneer Etching Process Sep 11, 2017

Los ntawm degreasing → ntxuav → acid corrosion → ntxuav → ntxuav → alkali corrosion → ntxuav → ntxuav → ntxuav → ntxuav → ntxuav → ntxuav → oxidation.

Profiles tom qab thawj zaug acid corrosion, tom qab alkali corrosion, lub teeb, ua ntej qhov kawg ntawm pov tseg. Qhov nruab nrab ntawm kev siv tshuab yog acid, cuam tshuam cov qauv, los ntawm cov xuab zeb, thiab lwm yam. Txawv ntawm cov dab noj kom haum alkaline, qhov loj tshaj plaws ntawm cov kua qaub ntawm cov kua qaub yog ua kom muaj zog, los ntawm cov xuab zeb sai, qis siv aluminium, feem ntau yog 3-5 feeb kom tiav, aluminium yog yuav luag alkaline etching 1 / 8-1 / 6 .

Txawm li cas los xij, qhov teeb meem ntawm cov kab mob qog ntawm cov kua qaub (corrosion) nce ntxiv: cov kua qaub av ntawm cov roj tovic HF kev khiav tawm thiab kev ua kom muaj kuab paug ntxuav. Cov tshuaj fluorides mas feem ntau muaj kev phom sij thiab pov tseg tsis yooj yim. Tsis tas li ntawd, tom qab kho cov kua qaub ntawm cov kua qaub, cov tsos ntawm cov plaub hau tsaus nti, txawm tias qhov kawg nruam alkali yaig thiab lub teeb, muaj peev xwm tau ci ntsa iab, tiam sis tseem tsaus heev, ob qho tib si kom nce txoj kev, tab sis kuj ploj lub luster, uas kuj xav tau txhuas cov vuas tshuab kom zoo.

Aluminium veneer etching txheej txheem zoo tuaj yeem ua rau cov khoom muaj txiaj ntsig zoo ntawm cov txhuas veneer thiab txo cov nqi ntawm cov txhuas veneer ntau lawm, thiab ua rau muaj kev ua qias tuaj. Yog li ntawd, cov txhuas veneer cov lag luam tseem yuav tsum ua qhov tsim nyog tiv thaiv ib puag ncig tiv thaiv kev ntsuas, tus qauv ntawm kev loj hlob zoo.
