Kukho okungakumbi nangakumbiizithuba ze-galvanizedkwimarike, ngoko ke yintoni i-galvanizing? I-galvanizing ngokubanzi ibhekisa kwi-hot dip galvanizing, inkqubo egubungela intsimbi ngomaleko we-zinc ukuthintela ukugqwala. Intsimbi intywiliselwa kwi-zinc enyibilikisiweyo kubushushu obumalunga ne-460°C, nto leyo edala i-metallurgical bond eyenza umaleko okhuselayo.
Indima ye-hot dip galvanizing
Indima ye-hot dip galvanizing kukubonelela ngokhuseleko lokugqwala kwi-substrate yentsimbi, inceda ekwandiseni ubomi bezinto ezisetyenzisiweyo. Le nkqubo inceda ekuthinteleni ukugqwala kunye nezinye iintlobo zokugqwala, okunokubangela umonakalo kwisakhiwo kwiindawo zesinyithi kwaye kukhokelela ekwaphulweni. I-hot dip galvanizing ibalulekile kwiintlobo ngeentlobo zezicelo kuquka ulwakhiwo, uthutho kunye neziseko zophuhliso.
Ukusetyenziswa kwe-hot dip galvanizing
I-dip galvanizing isetyenziselwa ukukhusela intsimbi yesakhiwo ekuboleni, ukuqinisekisa ukuba izakhiwo nezinye izakhiwo zihlala zizinzile kwaye zikhuselekile. Kwishishini lothutho, i-hot dip galvanizing inceda ekuthinteleni ukubola kwezithuthi, iitreyila, iibhulorho kunye nezinye izibonelelo. Ekukhuseleni izinto zesinyithi ekuboleni nasekuqinisekiseni ubomi benkonzo yezakhiwo ezahlukeneyo kunye nezinto.
Imigangatho yokucoca nge-hot dip
Imigangatho ye-hot dip galvanizing (HDG) iyahluka ngokwelizwe kunye noshishino.
1. I-ASTM A123/A123M – Inkcazelo Esemgangathweni Yezinki (I-Hot Dip Galvanized) Iingubo kwiMveliso yentsimbi neyentsimbi
2. ISO 1461 – Iingubo ezishushu ezigqunywe ngentsimbi kunye neemveliso zentsimbi – Iinkcukacha kunye neendlela zovavanyo
3.BS EN ISO 1461 – Iingubo ezishushu ezigqunywe ngentsimbi kunye nentsimbi – Iinkcukacha kunye neendlela zovavanyo
Le migangatho inika isikhokelo malunga nobukhulu, ukwakheka kunye nokubonakala kweengubo ezigqunyiweyo kunye neendlela ezahlukeneyo zokuvavanya ukuqinisekisa umgangatho weengubo.
Ukuba unomdla kwi-hot dip galvanizing, wamkelekile ukuba uqhagamshelane nomenzi weposi ye-galvanized uTIANXIANG ukuze akuncede.Funda ngokugqithisileyo.
