Kuthunyelwe ku 2015-10-26Ubuchwepheshe be-Dacromet baqala eminyakeni engamashumi ayisikhombisa yekhulu lama-20, i-United States, i-China ngawo-1980 yethula ubuchwepheshe be-Dacromet, futhi ngokusebenzisa ukugaya nokumuncwa, futhi kancane kancane ibona imishini yenqubo kanye, i-Dacromet fluid yendawo.Ngo-2002, i-State Administration of quality supervision, inspection and Quarantine yakhipha indinganiso kazwelonke "GB/T18684-2002 zinc chromium coating coating conditions".
Ubuchwepheshe be-Dacromet buye baheha ukunakwa okwengeziwe kwabacwaningi namabhizinisi ahlobene nezici zabo eziphakeme.Izici zokumboza ze-Dacromet:
I-1, indawo enobungane iDacromet ngendlela umjikelezo ovaliwe, e-Dacromet enamathela kanye nenqubo yokuphulukisa yokuhwamuka komhwamuko wamanzi kanye nenani elincane lezinto eziphilayo zingaphakathi kobubanzi obunqunywe nguhulumeni, ayikho inqubo yendabuko ye-electroplating ekukhiqizeni ubuningi bokungcola. namanzi amoshayo.Ngakho-ke, i-Dacromet ngandlela-thile phezulu engase ibizwe ngokuthi ubuchwepheshe "obuluhlaza".
2, ukumelana nokugqwala okuphezuluI-Dacromet coating antirust effect iphakeme ngokuphindwe ka-7-10 kunaleyo ye-electro galvanized yendabuko, indlela yokugcoba eshisayo noma yopende kanye nezinga le-Dacromet yokumboza ukumelana nokuhlolwa kwenkungu kasawoti ngaphezu kwamahora angu-1200 ngemva kokuba ingakabonakali ibomvu. ukugqwala, ukugqwala okuqinile okubonakalayo.
I-3, ukumelana nokushisa okuphezuluUma kuqhathaniswa nongqimba lwendabuko lwama-galvanized lwefilimu ye-passivation ephakeme kune-70 DEG C i-dehydrated cracking phenomenon, ukugqoka kwe-Dacromet ekushiseni okuphezulu kwe-500 DEG C kusengakwazi ukugcina ukusebenza okuzinzile, ukumelana nokugqwala kuhle kakhulu.
4, akukho embrittlement hydrogen Dacromet enamathela ngaphandle pickling acid kanye ekwelapheni emazingeni okushisa aphezulu, kusukela inqubo inquma akukho hydrogen embrittlement mkhuba, efanelekayo high izingxenye amandla kanye nelungu entwasahlobo.
I-5, ukungena okuphezulu, i-adhesionDacromet ngendlela yokwelashwa kokucwiliswa, ayinqunyelwe ukuma kwe-workpiece;ukunamathela okuhle akubonakali kuphela ku-matrix, futhi enye i-coating eyengeziwe nayo inokunamathela okuqinile.
I-Changzhou Junhe Technology Stock Co., Ltd.ukuzibophezela ekukhiqizeni ngamakhemikhali amahle, amathuluzi akhethekile kanye nohlelo lokuxazulula isevisi luhlinzeka ngamabhizinisi azimele zobuchwepheshe obuphezulu.Uzibophezele ocwaningweni lwezobuchwepheshe lwe-Dacromet kanye ne-Dacromet, inemigqa yokukhiqiza yokugqoka i-Dacromet kanye nemishini ye-Dacromet ethuthukisiwe, imishini yokugqoka i-Dacromet, umshini wokugcoba we-Dacromet kanye nekhwalithi ye-Dacromet yokuhlanganisa uketshezi.
