Ukulawulwa kwekhwalithi ye-roll enkulu yama-galvanized wire enamathela

1. Lungisa imingcele yenqubo ye-electroplating

Lawula ngokuqinile inani le-pH lomqulu omkhuluucingo lukathayelaokugeza, ucwaningo lubonisa ukuthi ubukhulu pH value okugeza kuthinta ngqo izinga steel wire enamathela, ukulawulwa okungafanele pH value kuzobangela enamathela okuxekethile.Uma inani le-pH likhulu kuno-3, izintambo zensimbi zine-burr ebangelwa ama-dendrites amahle, futhi ingaphezulu alisheleli.Ukuminyana kwamanje kulawulwa ngokuqinile.Kusuka ku-microscopic morphology, ukuphakama kokuminyana kwamanje, ungqimba lwezinki olukhudlwana ukubekwa okusanhlamvu, ungqimba oluhambisanayo lwezinc luyancipha.

Ngokuphambene nalokho, i-denser deposition ye-ion, ingcono izinga le-zinc layer.Ngaphansi kwesimo sokuthi ungqimba lwezinc olungaphezulu luminyene futhi lugqamile, izinga le-zinc layer endaweni ngayinye kufanele lifinyelele ku-80g/m2, futhi imingcele yenqubo kufanele ithuthukiswe ngale ndlela elandelayo: ukuminyana kwamanje ngu-16-20A / dm2, ukuhlushwa okukhulu kwe-zinc. Isixazululo se-sulfate singama-500g/L, kanti inani le-pH lingu-2.5-3.0.

2. Lungisa imingcele yenqubo yokudweba ithangi lamanzi

Ngokuhambisana ngokuqinile nomdwebo wezinga lokucindezela elincane le-multi-pass, izinga lokucindezela eliphelele liyi-96.48%, linciphisa ukukhuhla kwe-zinc layer.Yonke imidwebo yocingo yenziwe nge-tungsten steel die kanye ne-polycrystalline die.I-engeli yekhoni esebenzayo yomdwebo wentambo yokufa ingu-12 ° ~ 16 °, futhi ubude bebhande lokulinganisa buyi-0.15 yobubanzi bocingo, ukuze kuqinisekiswe ukuthi ukuguquguquka kongqimba lwe-zinc ngokuyisisekelo kuyavumelana i-steel wire substrate.

Isistimu yomjikelezo wokupholisa isebenzisa isifutho ukuze ipholise ukufa komdwebo, futhi isusa ukushisa okuningi okukhiqizwa umshini wokudweba ekudwebeni kwesivinini esiphezulu ngesikhathi ukuze kuqinisekiswe ikhwalithi yocingo.Lawula imingcele yenqubo yokudweba: isivinini sokudweba 10 ~ 12m / s;Ukuqina kokuqina 8 ~ 10N;Ukulinganisa ubude 30km;Ingxenye enkulu ye-lubricant ingu-3.5 ~ 4.5%;I-pH yenani lokuthambisa 7 ~ 8;Amazinga okushisa okuthambisa 30 ~ 40 ℃.

Ngemuva kokwenziwa kahle kwenqubo, ukukhiqizwa okukhulu kwe-0.80mm electroucingo oluyinsimbiikhwalithi ye-electro galvanized zinc layer ilawulwa ngaphakathi kwe-80 ~ 90g/m2, ukuhlakazwa kwekhwalithi ye-zinc kuncane kakhulu;Imiphumela ibonisa ukuthi isisindo esijwayelekile se-zinc layer singu-14.5g/m2, ukulahlekelwa kwe-zinc layer kungaphansi kuka-5%, futhi amandla aqinile ocingo lwensimbi ngu-2300 ~ 2500MPa.Ayigcini nje ngokulawula ngempumelelo izinga le-zinc layer yocingo lwensimbi eluhlaza, kodwa futhi inciphisa imfucuza engadingekile nezindleko zokukhiqiza.
