Umbhobho okhethekileyo owenziwe igalvan ukuze uphume
Inkcazelo emfutshane:
Umbhobho ofakwe igalvanized, owaziwa ngokuba ngumbhobho wentsimbi, wahlulwe waba yigalvanizing eshushu kunye ne-electro galvanizing.I-hot-dip galvanizing layer ingqindilili kwaye ineengenelo zokwaleka okufanayo, ukuncamathela okuqinileyo kunye nobomi benkonzo ende.Iindleko ze-electro galvanizing ziphantsi, umphezulu awugudi kakhulu, kwaye ukuchasana kwayo nokugqwala kubi kakhulu kunombhobho oshushu wokudipha.
Idiphu eshushu umbhobho wentsimbi
Ukusabela okuntsonkothileyo komzimba kunye neekhemikhali kwenzeka phakathi kwe-matrix yombhobho wentsimbi kunye nesisombululo esinyibilikisiweyo se-plating ukwenza umaleko we-zinc ferroalloy onganyangekiyo kunye nesakhiwo esibambeneyo.Uluhlu lwe-alloy luhlanganiswe ne-zinc ecocekileyo kunye ne-matrix yepayipi yensimbi.Ngoko ke, inokumelana ne-corrosion enamandla.
Emva kophuhliso ukusuka kwi-1960 ukuya kwi-1970, umgangatho wemveliso yombhobho wensimbi oshushu-dip uphuculwe kakhulu.Ukusukela ngo-1981 ukuya kowe-1989, ibisoloko ihlelwa njengemveliso ekumgangatho ophezulu woMphathiswa wezoMetalurgy kunye nembasa yesilivere yesizwe.Imveliso nayo iye yanda iminyaka emininzi.Isiphumo sasingaphezu kweetoni ezingama-400000 ngo-1993 kunye neetoni ezingaphezu kwama-600000 ngo-1999.Imibhobho yediphu yediphu eshushu isetyenziswa kakhulu njengemibhobho yothumelo lwamanzi kunye nemibhobho yerhasi, eneenkcukacha eziqhelekileyo + 12.5 ~ + 102 mm.Ukusukela ngeminyaka yoo-1990s, ngenxa yengqwalasela karhulumente kukhuseleko lwendalo esingqongileyo kunye nolawulo olungqongqo ngakumbi nangakumbi kumashishini angcolisekileyo, “inkunkuma emithathu” eveliswe kwimveliso yemibhobho efakwe intsimbi eshushu ediphu kunzima ukuyicombulula, idityaniswa nophuhliso olukhawulezayo lwezitshizi ezingenastainless. imibhobho yentsimbi edityanisiweyo, imibhobho yePVC kunye nemibhobho edibeneyo, kunye nokukhuthazwa kwezinto zokwakha iikhemikhali kunye nothintelo lokusetyenziswa kwemibhobho yentsimbi, Uphuhliso lombhobho odibeneyo oshushu-diphu wawuthintelwe kakhulu kwaye ulinganiselwe, kunye nophuhliso olushushu. -dip galvanized welded pipe yayicotha.
Umbhobho obandayo wentsimbi
Uluhlu lwe-zinc luluhlu lwe-electroplating, oluhlukaniswe kwi-matrix yombhobho wensimbi.Uluhlu lwe-zinc luncinci, kwaye i-zinc layer ifakwe nje kwi-matrix yepayipi yensimbi, elula ukuwa.Ngoko ke, ukuxhathisa kwayo kukonakala.Kwizindlu ezitsha, akuvumelekanga ukusebenzisa imibhobho yentsimbi ebandayo njengemibhobho yokuhambisa amanzi.
