Dab tsi yog cov txheej txheem rau kev kho saum npoo ntawm cov khoom siv txhuas? Muaj ntau cov txheej txheem rau kev kho saum npoo ntawm txhuas, nrog rau lub hom phiaj kawg ntawm kev tiv thaiv cov khoom zoo. Niaj hnub no, peb yuav muab cov ncauj lus qhia ntxaws ntxaws rau ntau qhov txheej txheem kev kho saum npoo.
1. Electrophoretic txheej. Nyob rau hauv lub hauv paus ntawm anodic oxidation, ib txheej ntawm dej-soluble acrylic xim zaj duab xis yog sib npaug zos rau ntawm anodic oxidation zaj duab xis los ntawm electrophoresis, tsim ib tug puas zaj duab xis ntawm anodic oxidation zaj duab xis thiab acrylic xim zaj duab xis rau ntawm qhov profile. Qhov kov yog du thiab muag heev, nrog rau qhov zoo nkauj thiab ci ntsa iab. Ntxiv nrog rau kev tsim cov xim qub anodized, nws tuaj yeem tsim cov xim zoo nkauj dua li xim dawb thiab ntsuab.
2. Muaj yeeb yuj hmoov txau. Kev ua haujlwm ruaj khov, muaj zog adhesion ntawm cov xim zaj duab xis, tiv thaiv tev, kua qaub, tshuaj tiv thaiv ntsev, tshuaj tiv thaiv, huab cua tsis kam, kev laus ua haujlwm, thiab lwm yam haujlwm zoo heev. Cov txheej yog tsis volatile, tsis oxidizing, thiab tsis muaj kuab paug nyob rau hauv cov huab cua, nrog zoo ib puag ncig tiv thaiv functions.
3. Muaj yeeb yuj fluorocarbon txau. Txau cov tshuaj polyvinylidene fluoride pleev xim rau saum npoo ntawm aluminium alloy substrate los ntawm cov nyhuv electrostatic. Fluorocarbon txheej yog ib hom vinylidene fluoride thiab fluorocarbon txheej, yog li nws tuaj yeem muaj xim ruaj khov, tiv thaiv kev laus, tiv thaiv corrosion thiab huab cua tsis zoo. Nws daim ntawv cog lus fluorocarbon yog ib qho ntawm cov khoom muaj zog tshaj plaws molecular bonds, superior rau nws cov qauv molecular polymerized.
4. Hlau kos duab kho. Aluminium lossis aluminium alloys yog qhov tsim nyog rau kev kho cov hlau kos duab, thiab cov duab kos yog qhov tseeb tsis cuam tshuam rau sab nraud oxidation. Hlau kos duab yuav tsum tau ua ua ntej anodizing; Lwm txoj kev anodic oxidation tsis tuaj yeem siv tau lawm. Cov tsos mob tau txais los ntawm ntuj oxidation yuav tsum raug hu ua qhov tsis zoo, thiab nws cov oxide zaj duab xis yog txawv kiag li nyob rau hauv muaj pes tsawg leeg thiab tsos los ntawm tshwj xeeb kho oxide zaj duab xis.
5. Anodizing thiab xim. Xim anodized zaj duab xis - Cov yeeb yaj kiab anodized ntawm txhuas, uas yog xim los ntawm adsorbing dyes. Spontaneous xim anodic oxide zaj duab xis - Qhov no anodic oxide zaj duab xis yog xim anodic oxide zaj duab xis spontaneously generated los ntawm ib tug tshwj xeeb txhuas cov ntaub ntawv nyob rau hauv ib tug haum electrolyte (feem ntau raws li organic acids) nyob rau hauv electrolysis nyhuv. Electrolytic coloring: Cov xim ntawm cov anodic oxide zaj duab xis yog ua tiav los ntawm electrodepositing hlau lossis hlau oxides los ntawm qhov chaw qhib ntawm oxide zaj duab xis.
