Kutetezedwa katatu kwa chithandizo chapamwamba cha Dacromet

Adalemba pa 2018-08-13Mfundo ya chithandizo cha Dacromet pamwamba ndikulekanitsa kugwirizana pakati pa madzi, mpweya ndi chitsulo kuti mupeze mphamvu ya antiseptic.Mfundoyi makamaka ndi mgwirizano wa njira zitatu zotetezera.

Chotchinga chotchinga: Zinc ndi aluminiyamu wonyezimira mu zokutira zimadutsana pamwamba pa chitsulo kuti apange wosanjikiza woyamba woteteza, womwe umalepheretsa sing'anga yowononga monga madzi ndi okosijeni kukhudzana ndi gawo lapansi, lomwe limasewera kwambiri kudzipatula.

Passivation: Mu ndondomeko ❖ kuyanika mankhwala chromic asidi ndi nthaka, zotayidwa ufa ndi m'munsi zitsulo Dacromet, passivation filimu anapanga padziko ndi mankhwala anachita, filimu passivation si sachedwa dzimbiri anachita, komanso amachita ngati chotchinga.Zochita za corrosive media, pamodzi ndi zolepheretsa, zimapereka chitetezo chamagulu awiri chomwe chimalimbitsa zotsatira za kudzipatula.

Chitetezo cha Cathodic: Ichi ndiye chofunikira kwambiri choteteza.Mofanana ndi mfundo ya wosanjikiza kanasonkhezereka, chitetezo cathodic ntchito gawo lapansi pa mankhwala wosanjikiza ndi nsembe anode.

Kumbali imodzi, mitundu itatu yazitetezo iyi imatsekereza kuwononga kwa sing'anga yowononga pazitsulo.Kumbali imodzi, gawo lapansi lawonongeka ndi magetsi, ndipo sizodabwitsa kuti pali kangapo chitetezo cha zinki zachikhalidwe za electroplating.
