Yakatumirwa pa 2018-03-21Iko kushandiswa kwedacromet coating, makambani mazhinji 'standard mesh bhandi choto heaters anodzora preheat zone tembiricha 80 ~ 120 ℃。 Chinangwa chikuru chekupisa uku ndechekuburitsa hunyoro mukupfeka pasina kuvira, panguva imwe chete, inoperekedzwa zvirokwazvo. nekemikari maitiro ekuderedza hexavalent chromium nedoro.
Nzira yekutsunga iyi musanganiswa weDacromet B yakachena (aqueous chromic anhydride) uye polyethylene glycol reductant muchiyero.Iyo yakabikwa yakabikwa pagirazi slide uye inopisa pa 120 ° C kwemaminitsi gumi nemashanu.Mvura yakanyungudika uye chinhu chakasara chaiva firimu rakasviba rakasvibira.
Kana chidimbu chekuedza chichipisa kusvika kumaminitsi e120, ruvara rwejasi rinova rakasvibirira rakasvibirira, uye jira rinova rakaoma, asi rinogona kushambidzwa nemvura.Zviri pachena kuti hazvibviri kushandisa kupisa kwenguva refu pa 120 ° C kuti ushandise kuvhara kweDacromet.
