Tshem tawm cov coatings los ntawm cov iav coated tuaj yeem ua tiav los ntawm cov txheej txheem xws li cov kuab tshuaj lom neeg, lub cev polishing, thiab chav ntxuav, nyob ntawm seb hom, thickness, thiab cov khoom ntawm txheej. Cov txheej txheem kev nyab xeeb thiab kev tiv thaiv yuav tsum tau ua raws li thaum lub sijhawm ua haujlwm.
Cov txheej txheem tshuaj hnyav yog ib qho kev xaiv. Tshwj xeeb iav txheej tshem tawm tuaj yeem siv tau; Cov khoom me me yog tsim rau lub teeb txheej, thaum cov khoom muaj zog yog xav tau rau cov txheej tuab. Tom qab txau, maj mam so nrog ib daim ntaub mos muag. Rau txoj kev tu kom zoo dua qub, kev ntxuav tu tuaj yeem ua tau los ntawm kev sib xyaw ci dej qab zib, dawb vinegar, thiab dej hauv qhov sib piv 1: 1: 2. Tom qab tshuaj tsuag, tos ib pliag, ces maj mam txhuam nrog ib tug hniav thiab so nrog ib tug phuam qhuav dampened nrog dawb cawu cub. Lub cev polishing yuav tsum tau cov ntawv xuab zeb zoo los yog polishing muab tshuaj txhuam. Pib nrog cov ntawv xuab zeb zoo thiab nruj me ntsis tswj lub siab thiab lub sijhawm kom tsis txhob khawb lub iav nto. Kev ntxuav chav yuav siv siab - qhov kub thiab txias los ua kom cov txheej txheej softening, thiab tom qab ntawd so nrog ib daim ntaub. Txoj kev no ua rau muaj kev puas tsuaj tsawg rau lub khob, tab sis cov khoom siv kim dua thiab qhov kev tshem tawm ceev kuj qeeb.
Rau cov txheej txheem tshwj xeeb xws li evaporation coatings lossis magnetron sputtering coatings, siv txoj kev polishing siv hydrochloric acid thiab zinc hmoov. Txawm li cas los xij, vim tias hydrochloric acid yog corrosive, cov cuab yeej tiv thaiv xws li hnab looj tes thiab tsom iav yuav tsum tau hnav thaum ua haujlwm, thiab iav yuav tsum tau ntxuav kom huv si tom qab ntawd. Rau online evaporation txheej, HF chav fumigation tuaj yeem siv ua ntej, tom qab polishing nrog cerium oxide polishing hmoov. Hauv kev siv txhua hnub, lub tshuab ziab khaub ncaws tuaj yeem siv los ua kom cov txheej txheem softening thiab maj mam tev nws tawm, tab sis qhov no muaj kev txwv rau kev ua kom muaj txheej ruaj khov.
