Galvanized simbi pombi kazhinji ine zvine musoro mutengo unoshanda mumusika. Kuenzaniswa nemamwe akajairwa nesimbi pombi machira, senge pendi yakasarudzika uye poda coating, galvanization inonyanya kushanda nesimba, zvichikonzera mutengo wekutanga wevakontrakta. Kunze kwezvo, nekuda kwekugara kwayo uye anti-corrosive zvivakwa, galvanized simbi pombi inogona kudzokororwa uye kushandiswazve, iyo kune imwe nhanho inochengetedza mari yakawanda panguva yebasa rekugadzirisa.
Senyanzvi yekugadzira pombi yesimbi muChina, tinoda kukubatsira kuita mutsauko pakati pemhando huru nhatu dzesimbi dzakagadzirwa nenzira kwayo.
1) Hot dip galvanized simbi pombi:
Iyo inopisa dip galvanizing process ndipo panonyikwa chikamu chakatoumbwa, semuenzaniso ndiro, denderedzwa, sikweya kana rectangular simbi chubhu inonyikwa mubhavhu rezingi. Kuita kunoitika pakati pesimbi uye zingi panguva iyo chikamu chiri mubhavhu re zinc. Ukobvu hwekuputira zinc hunokonzerwa nehuwandu hwezvinhu, zvinosanganisira pamusoro pepombi yesimbi, nguva iyo pombi yesimbi inonyudzwa mubhati, kuumbwa kwepombi yesimbi pamwe nekukura kwepombi yesimbi uye ukobvu.
Imwe mukana wekupisa dip galvanizing ndeyokuti chikamu chose chakafukidzwa kusanganisira kumucheto, welds, nezvimwewo zvichipa iyo yose-yakapoteredza corrosion kudzivirira. Iyo yekupedzisira chigadzirwa inogona kushandiswa kunze mune ese akasiyana mamiriro ekunze. Iyo ndiyo inonyanya kufarirwa nzira yekugadzira uye inoshandiswa zvakanyanya muindasitiri yekuvaka.
2) Pre-galvanized simbi pombi:
Pre-galvanized simbi pombi inoreva pombi yesimbi yaive yakabatiswa ichiri mupepa fomati, nekudaro isati yaenderera mberi kugadzira. Pre-galvanization inozivikanwawo seguyo galvanized, nekuda kwekuti simbi inokungurutswa kuburikidza neyakanyungudutswa zinc. Mushure mekunge bepa ratumirwa nepaguyo kuti rive nemarara rinochekwa kusvika pakukura rodzokororwa. Ukobvu chaihwo hunoiswa pabepa rese, semuenzaniso pre-galvanized Z275 simbi ine 275g per square metre zinc coating. Imwe yezvakanakira iyo pre-galvanized simbi ine pamusoro inopisa dip galvanized simbi ndeyekuti ine chitarisiko chiri nani.
pre-galvanized zvinhu zvinoshandiswa kune zvakasiyana siyana zvigadzirwa zvinosanganisira conduit, miromo uye yakavhurika nzira.
3) Electro-galvanized simbi pombi:
Electro-galvanized steel pombi zvinoreva kuisa zingi jasi rinoiswa papombi yesimbi uchishandisa electro deposition. Electro-galvanized simbi pombi ine mukana wekuti ukobvu hwekufukidzira hunogona kudzorwa zvakazvimirira pane mukati uye kunze zvikamu. Ukobvu hwehuputi hunoshandiswa kuburikidza ne electro galvanization hwakajeka.
