Ukuthuthukiswa kobuchwepheshe kwe-Dacromet (i-zinc chrome coating)

Kuthunyelwe ku 2018-12-28I-Dacromet ukuguqulwa kwamaletha kwesiShayina kwe-DACROMETR, eyaziwa nangokuthi ifilimu ye-zinc chrome, i-Dak rust, i-Dakman, njll., futhi izobizwa ngokuthi "i-zinc chrome coating" ngokwezinga le-Dacromet yase-China.), okuchazwa ngokuthi: "I-Inorganic anti-corrosion coating ene-scaly zinc ne-zinc chromate njengezingxenye eziyinhloko ngokugcotshwa kwediphu, ukuxubha noma ukufafaza i-zinc-chromium esekelwe emanzini ebusweni bezingxenye zensimbi noma izingxenye. Ungqimba."Ubuchwepheshe be-Dacromet basungulwa ngabaseMelika futhi buyindlela yokwelapha yensimbi efana ne-electro-galvanizing.

I-Dacromet coating inokubukeka okufanayo kwesiliva-grey futhi iqukethe ama-80% ama-zinc flakes amancane embotsheni.Ishidi le-aluminium, elinye liyi-chromate, linokusebenza okuhle kakhulu, njengokumelana nokugqwala okuqinile: izikhathi ezi-7 kuye kweziyi-10 ngaphezu kwe-electrogalvanizing;i-anaerobic brittle;ezifanele ikakhulukazi izingxenye eziqine kakhulu, njengobunjiniyela besitimela esihamba ngaphansi komhlaba Amabhawodi anamandla amakhulu;ukumelana nokushisa okuphezulu;izinga lokushisa elimelana nokushisa ngu-300 °C.

Ngaphezu kwalokho, ibuye ibe nezinzuzo zokungena okuphezulu, ukunamathela okuphezulu, ukunciphisa ukungqubuzana okuphezulu, ukumelana nesimo sezulu esiphezulu, ukusimama okuphezulu kwamakhemikhali futhi akukho ukungcoliswa kwemvelo.

Emazweni athuthukile, ubuchwepheshe be-Dacromet metal surface anti-corrosion busetshenziswe njengendlela yokwelapha ukugqwala kwezinqubo eziningi zendabuko ezifana ne-electroplating, i-hot dip galvanizing, i-electroplating cadmium, i-zinc-based alloy plating, i-phosphating, njll. kunciphisa ngokuyisisekelo ukungcoliswa kwemvelo.

Ngenxa yokusebenza kwayo okulula, ukonga amandla, kanye nokungcoliswa kwemvelo okuphansi, ubuchwepheshe be-Dacromet bungagwema izinzuzo ze-zinc yendabuko ye-electroplating kanye nobuchwepheshe be-hot dip galvanizing obufana ne-hydrogen embrittlement.Ngakho-ke, ibisetshenziswa kabanzi kusukela ekuqaleni kwawo-1970, ikakhulukazi embonini yezimoto emazweni athuthukile njenge-United States ne-Japan, futhi iye yanwetshwa ekwakhiweni, ezempi, ekwakhiweni kwemikhumbi, kaloliwe, amandla kagesi, izinto zikagesi zasendlini, ezolimo. imishini, izimayini, amabhuloho, njll.
