Cov no, tshwj xeeb, suav nrog xws li pastes thiab hmoov xws li "Auto Cleaner", "Kama", "Tartarin", "Surzha" thiab lwm yam. Tsis muaj qhov tshwm sim tshwj xeeb, xeb tuaj yeem raug tshem tawm siv 15-20% kev daws teeb meem ntawm cov kua qaub ntawm cov organic keeb kwm (oxalic, piv txwv).
kev npaj nto
Ua ntej koj rov qab da dej nrog acrylic, koj yuav tsum ntxuav thiab qhuav lub hauv paus. Yog tias muaj cov khawb me me ntawm qhov chaw, ces nws txaus los ntxuav lawv nrog cov ntawv xuab zeb. Yog tias qhov tsis xws luag hnyav dua, ces koj yuav tau tshem tag nrho cov txheej txheem. Rau qhov no, lub laum nrog lub log abrasive yog siv. Nws yuav tsum tau muab sau tseg tias nyob rau hauv tus txheej txheem ntawm kev ua hauj lwm yuav muaj ib tug ntau ntawm plua plav. Yog li ntawd, nws yog ib qho tsim nyog los tshem tawm cov txheej hauv lub tshuab ua pa. Tom qab ntxuav nrogcov chaw yog ntxuav kom huv si ntawm cov av. Ces da dej yog kho nrog ib tug hnyav. Yog tias tsis yog, koj tuaj yeem siv baking soda. Nws yog diluted nyob rau hauv dej kom sib xws ntawm gruel. Tom qab kev kho mob, cov dej qab zib yog ntxuav tawm ntawm qhov chaw nrog dej kub.
Cov kab nrib pleb thiab chips yuav tsum tau kho. Rau qhov no, lub tshuab ziab khaub ncaws ceev ceev yog siv. Acrylic da dej restoration yog nqa tawm ntawm ib tug tej yam kub thiab txias. Cov dej kub ua ntej yog kos rau hauv lub tais. Cov khoom ntim tau khaws cia rau tsib feeb. Tom qab ntawd, dej yog drained. Qhov saum npoo ces dries sai. Rau qhov no, ib daim ntaub uas tsis tawm lint yog tsim nyog. Tam sim ntawd ua ntej koj pib rov qab da dej nrog koj tus kheej txhais tes, nws yog ib qho tsim nyog yuav tsum rhuav tshem cov dej ntws (sab sauv thiab qis). Hauv qhov no, lub thawv yuav tsum tau muab tso rau hauv qab lub tais ntawm theem ntawm lub qhov.
