I-Hot Dip Galvanized Steel

Amapayipi ensimbi anamapayipi ensimbi ashiselwe anezingqimba ezifakwe emanzini ashisayo noma ze-electro-galvanized ngaphezulu. I-galvanizing ingakhuphula ukumelana nokugqwala kwepayipi lensimbi futhi yandise impilo yayo yesevisi. Amapayipi anamathangi anezinhlobonhlobo zokusetshenziswa. Ngaphezu kwamapayipi kalayini okudlulisa amanzi, igesi, uwoyela kanye nolunye uketshezi oluvamile olunomfutho ophansi, abuye asetshenziswe njengamapayipi emithombo kawoyela namapayipi kawoyela embonini kawoyela, ikakhulukazi izindawo zikawoyela ezingasogwini, kanye nezishisi zikawoyela kanye ne-condensate uma kuphekwa amakhemikhali. imishini. Amapayipi ama-coolers, izishintshi zikawoyela ohlanzwa ngamalahle, inqwaba yamapayipi amabhuloho adonsa kanzima, amapayipi ohlaka lokusekela lwemigudu yezimayini, njll.

Ipayipi elinothayela lediphu elishisayo elokwenza insimbi encibilikisiwe kanye ne-iron matrix kusabela ukuze kukhiqizwe ungqimba lwengxubevange, ukuze i-matrix kanye nokunamathela kuhlanganiswe. I-hot-dip galvanizing iwukuba ugqume ipayipi lensimbi kuqala. Ukuze kukhishwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokuchotshozwa, ihlanzwa ethangini le-ammonium chloride noma i-zinc chloride isixazululo samanzi noma isixazululo esinamanzi esixubile se-ammonium chloride ne-zinc chloride, bese sithunyelwa ku-In. ithangi le-dip plating elishisayo. I-hot-dip galvanizing inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile nokuphila isikhathi eside. I-matrix yepayipi lensimbi elinothayela elishisayo idiphu ibhekana nokusabela okuyinkimbinkimbi ngokomzimba namakhemikhali ngesisombululo sokucwenga esincibilikisiwe ukuze kwakhe ungqimba lwengxube ye-zinc-iron engagqwali enesakhiwo esihlangene. Isendlalelo se-alloy sihlanganiswe nesendlalelo se-zinc ehlanzekile kanye ne-matrix yepayipi yensimbi, ngakho ukumelana kwayo nokugqwala kunamandla.
