Kodi mfundo ya anticorrosion ya zokutira za Dacromet ndi iti?

Adalemba pa 2018-05-07Ndi chitukuko chofulumira cha luso lamakono lamakono, zinthu zambiri zamakono zakhala zikugwiritsidwa ntchito.Ukadaulo wokonza umabweretsa zabwino zambiri pamoyo wathu.Dacromet iyenera kumvetsetsedwa ndi anthu ambiri.

Dacromet ili ndi ntchito m'mafakitale ambiri.Tekinoloje ya Dacromet tsopano ikuphatikizidwa ndi zokutira zambiri.Ikhoza kusewera bwino kwambiri anti-corrosion effect pamtunda wa mankhwala.Nanga n’cifukwa ciani imakwanitsa kusunga nkhaniyo?

Kupaka kwa Dacromet, mawonekedwe ndi matt siliva-imvi, wopangidwa ndi zinki zabwino kwambiri zachitsulo, aluminiyamu ndi zida za chromate.Chidutswacho chitatha kuchotsedwa ndikuwomberedwa, Dacromet idakutidwa.

Dacromet liquid ndi mtundu wa madzi opangira madzi.Zitsulo zoviikidwa kapena kupopera mankhwala mu njira yothetsera madzi, kenako zimakhazikika mu ng'anjo ndikuwotcha pafupifupi 300 ° C. kuti apange zokutira za zinki, aluminium ndi chromium.Akachiritsidwa, chinyezi mu filimu yokutira, organic (ma cellulose) ndi zigawo zina zosasunthika zimagwedezeka, ndipo katundu wa oxidizing wa mchere wa chromium wapamwamba kwambiri mu mowa wa amayi a Dacromet amachititsa kuti mphamvu ya electrode ikhale ndi phindu lalikulu loipa.

Pambuyo pa aluminiyumu zojambulazo slurry ndi matrix achitsulo, mchere wa chromium wa Fe, Zn, ndi Al umapangidwa.Chifukwa filimuyi imapezeka mwachindunji pambuyo pa gawo lapansi, anti-corrosion wosanjikiza ndi wandiweyani kwambiri.Pansi pa malo owononga, zokutirazo zimapanga mabatire ambiri oyambira, ndiye kuti, mchere woyipa wa Al ndi Zn udzachotsedwa poyamba mpaka utatha kuwononga gawolo likatha.
