I-St37 St52 A214 A178 A53 A423 Umbhobho oWelding weGalvanised, ERW

I-St37 St52 A214 A178 A53 A423 Umbhobho oWeldiweyo weGalvanised, Umfanekiso oPhambili we-ERW

Inkcazo emfutshane:

Inkcazo yemveliso:

Umbhobho we-galvanized oshushu wenzelwe ukwenza i-metal enyibilikisiweyo kunye ne-iron matrix reaction kwaye ivelise umaleko we-alloy, ukuze i-matrix kunye nomaleko wokugquma zidityaniswe. I-hot galvanizing ngumbhobho wentsimbi kuqala, ukuze kususwe i-iron oxide kumphezulu wombhobho wentsimbi, emva kokuyikha, ngokusebenzisa isisombululo se-ammonium chloride okanye i-zinc chloride okanye itanki yesisombululo esixutyiweyo se-ammonium chloride kunye ne-zinc chloride, ize ithunyelwe kwitanki ye-hot dip plating. I-hot-dip galvanizing ineengenelo zokugquma okufanayo, ukunamathela okuqinileyo kunye nobomi benkonzo ende. I-complex physical and chemical reaction yenzeka ngesisombululo se-melted plating sombhobho wentsimbi we-hot-dip galvanized, okwenza umaleko we-alloy yesinyithi oqinileyo nongamelaniyo nokugqwala. Umaleko we-alloy udityaniswe nomaleko we-zinc ococekileyo kunye ne-iron tube matrix, ngoko ke ukumelana kwayo nokugqwala kunamandla.

Imibhobho yentsimbi edityanisiweyo egayiweyo ukuze kuhanjiswe ulwelo oluphantsi koxinzelelo

1. Ukufana komaleko we-galvanized: isampuli yombhobho wentsimbi iqhubeka ifunxwa kwisisombululo se-copper sulfate amaxesha ama-5 ngaphandle kokuba bomvu (umbala we-copper plating)
2. umgangatho womphezulu: umphezulu wombhobho wentsimbi ogqunyiweyo kufuneka ube nomaleko opheleleyo ogqunyiweyo, kungabikho mabala amnyama angagqunywanga kunye namaqamza, kwaye uvumele ukuba kubekho umphezulu omncinci orhabaxa kunye nethumba le-zinc lendawo.
3. Ubunzima bomaleko we-galvanized: ngokweemfuno zomceli-mngeni, umbhobho wentsimbi we-galvanized ungasetyenziswa njengomlinganiselo wobunzima bomaleko we-zinc, kwaye ixabiso eliqhelekileyo aliyi kuba ngaphantsi kwe-500g / square meter, apho nayiphi na isampuli ayizukuba ngaphantsi kwe-480g / square meter.
