Ukugquma okuKhuselayo kwe-ASTM A106 GR.B
Iigalvanized
I-galvanizing yindlela yokubonelela ngokukhuselwa kwe-corrosion ngokusebenzisa i-zinc coating kumphezulu wentsimbi.
Obona buchule buxhaphakileyo bokwenza inkenteza kukugalela idiphu eshushu, apho umbhobho wentsimbi uthi nkxu kwi-zinc etyhidiweyo ukuze wenze umaleko oshinyeneyo we-zinc kumphezulu wawo.
Olu luhlu lwe-zinc alugcini nje ngokukhusela i-substrate yensimbi emoyeni nasemanzini, lukhusela i-oxidation, kodwa lunciphisa izinga le-corrosion yensimbi ngokukhuselwa kwe-anodic yedini (i-zinc isebenza ngakumbi kunentsimbi).
Umbhobho wentsimbi owenziwe ngesinyithi oshushu-dip ulungele ukusetyenziswa ngaphandle okanye kwiindawo ezimanzi, ezifana nezixhobo zokucocwa kwamanzi kunye nezakhiwo zangaphandle zokwakha.
Ukwaleka
I-Coating yindlela yokuthintela ukubola ngokufaka enye okanye ngaphezulu kweengqimba ze-anti-corrosion ye-coating ethile kumphezulu wepayipi yensimbi.
Ezi zambatho zinokuba yi-epoxy, i-polyurethane, i-polyethylene, okanye ezinye izinto zokwenziwa.
Iingubo ze-epoxy zisetyenziswa ngokubanzi kwimibhobho yemizi-mveliso ngenxa yozinzo olugqwesileyo lweekhemikhali kunye nokunamathela.
Umsebenzi oyintloko wokugquma kukuthintela umswakama kunye neekhemikhali ezitshabalalisayo, ukuthintela ukuba badibane ngqo nentsimbi.Ukunyangwa kwe-coating ifanelekile kuluhlu olubanzi lweendawo ezifana nezityalo zekhemikhali, iindawo zaselwandle kunye nothungelwano lwemibhobho yasezidolophini.
I-Lining Coating
Ukunyangwa kwe-lining kukusebenzisa umaleko wezinto ezichasene ne-corrosive, ezifana ne-epoxy resin, i-ceramics, okanye i-rubber, ngaphakathi kombhobho wentsimbi ukuthintela ukubola kwendlela yokuhambisa kudonga lwangaphakathi lombhobho wensimbi.
Le ndlela ifaneleke ngokukodwa ukuhambisa ulwelo oludlekayo (umz. iiasidi, iialkali, izinyibiliko zetyuwa, njl. njl.).
I-Epoxy resin lining inika umaleko oqinileyo wokuchasana nokonakala okwaziyo ukumelana nenqanaba elithile lokuhlaselwa kweekhemikhali kunye nokuqhawuka komzimba.
Ulwelo alunandisi nje kuphela ubomi bombhobho kodwa lukwagcina ukucoceka kolwelo nokuthintela ukungcoliseka.
