1. Amacandelo acutshungulwayo kunye neemveliso ezigqityiweyo aziyi kuchithwa ngaphandle ngaphandle kokuba zamkelwe ngamava.

2. I-burrs kumphezulu ongaphandle weumbhobho wentsimbi odityanisiweyo, ulusu lwe-welding, i-welding knobs, i-spatters, uthuli kunye nesikali, njl njl. kufuneka zicocwe ngaphambi kokususa i-rust, kunye ne-loose oxide scale kunye ne-rust layer kufuneka isuswe ngaxeshanye.

3. Ukuba kukho ioli kunye negrisi phezu kombhobho wensimbi odibeneyo, kufuneka ihlambuluke ngaphambi kokususwa kwe-rust.Ukuba kukho amabala e-oyile kunye negrisi kwindawo kuphela yendawo, iindlela zokulahla inxalenye zihlala zikhethwa;ukuba kukho iindawo ezinkulu okanye zonke iindawo, unokukhetha i-solvent okanye i-alkali eshushu yokucoca.

4. Xa kukho i-asidi, i-alkali, kunye neetyuwa kumphezulu wombhobho wentsimbi odityanisiweyo, unokukhetha ukuhlamba ngamanzi ashushu okanye umphunga.Nangona kunjalo, ingqalelo kufuneka ihlawulwe ukulahlwa kwamanzi amdaka, angenako ukubangela ukungcoliseka kwendalo.

5. Eminye imibhobho esanda kusongwa yentsimbi engenasici igqunywe ngepeyinti yokunyanga ukuze igweme umhlwa ngexesha lokugcinwa kwexesha elifutshane kunye nokuthutha.Imibhobho yensimbi engenasici efakwe ngepeyinti yokunyanga iya kuchithwa ngokwemiqathango ethile.Ukuba ipeyinti yokunyanga i-coating yamacandelo amabini enyangwa yi-arhente yokunyanga, kwaye i-coating is basically intact, inokunyangwa ngelaphu le-emery, i-velvet yensimbi engenasici okanye ukuqhuma ukukhanya, kunye nothuli lunokususwa, kwaye emva koko okulandelayo. inyathelo lokwakha .

6. Ukugquma ukunyanga i-primer okanye i-primer yesiqhelo yendawo yangaphandle yombhobho wentsimbi edibeneyo idla ngokumiselwa ngokwesimo sokugquma kunye nepeyinti exhasayo elandelayo.Nantoni na engenakusetyenziselwa ukugubungela ngakumbi okanye ichaphazela ukunamathela kwengubo elandelayo kufuneka isuswe ngokupheleleyo.
