Hot-dip galvanized pipe

Simbi yakanyungudutswa inopindirana nesimbi matrix kuti ibudise alloy layer, kuitira kuti matrix nejasi zvibatane. Kupisa dip galvanizing ndiko kutanga kunhonga pombi yesimbi, kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, kuburikidza neammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride yakasanganiswa aqueous solution tank yekuchenesa, uyezve mudip plating tank inopisa. Kupisa dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa. Mazhinji emaitiro ekuchamhembe anotora zinc replenishment process yegalvanized bhandi yakananga coil pombi.

Pombi inotonhora

Cold galvanized imagetsi emagetsi, marita idiki kwazvo, ingori 10-50g/m2, yayo yekudzivirira ngura yakasiyana zvakanyanya pane inopisa galvanized pombi. Vagadziri vepombi dzenguva dzose, kuitira kuti vave nechokwadi chehutano, vazhinji havashandisi magetsi emagetsi (kutonhora plating). Iwo chete mabhizinesi madiki ane midziyo isingachashandi anoshandisa magetsi emagetsi, hongu, mitengo yavo yakachipa. Mune ramangwana, mapaipi anotonhora anotonhora haabvumidzwe kushandiswa semvura uye gasi pombi.

Hot-dip galvanized steel pipe

Kusangana kwakaoma kwemuviri uye kemikari kunoitika pakati pesimbi chubhu substrate uye yekugezesa yakanyungudutswa kuti iite yakasimba zinc-iron alloy layer ine corrosion resistance. Iyo alloy layer inosanganiswa neyakachena zinc layer uye simbi pombi matrix. Nokudaro, kurwisana kwayo nekuora kwakasimba.

Mushure mekuvandudzwa kwekupisa kwesimbi pombi muma1960 kusvika kuma1970, mhando yechigadzirwa yakavandudzwa zvakanyanya, 1981 kusvika 1989 yakapihwa Metallurgical Ministry yezvigadzirwa zvemhando yepamusoro uye mubairo wesirivheri yenyika, kugadzirwa kwakawedzerawo kwemakore mazhinji, 1993 kubuda kweanopfuura 400,000 matani, 1999 matani, 1999. Southeast Asia, Africa, United States, Japan, Germany Nyika uye matunhu. Mapombi anopisa-dip galvanized anonyanya kushandiswa sepombi dzemvura nemapombi egasi, uye zvinozivikanwa ndezve +12.5~+102 mm. Mushure memakore ekuma1990, nekuda kwekutarisisa kwehurumende nezvekuchengetedzwa kwezvakatipoteredza, kutonga kwemabhizinesi ezvekusvibisa zvakanyanya kuri kuramba kuchiwedzera kuomarara, "marara matatu" anogadzirwa mukugadzirwa kwepombi dzinopisa-dip akabatiswa zvakaoma kugadzirisa, pamwe nekukurumidza kuvandudzwa kwesimbi isina tsvina yakashongedzwa pombi, mapaipi ePVC uye kusimudzira kushandiswa kwemapombi ehurumende, kusimudzira kushandiswa kwemakemikari ekuvaka, pamwe nekugadzira mapombi ehurumende. mapaipi esimbi anoganhurirwa, zvichiita kuti kuvandudzwa kwepombi dzinopisa-dhibha dzakarukwa dzakakandwa dzakakanganiswa zvakanyanya Beam uye muganhu, inopisa dip galvanized welded pombi yakazogadzirwa zvishoma nezvishoma.

Pombi inotonhora yesimbi

Iyo zinc layer ndeye yemagetsi, uye zinc layer yakazvimiririra yakaturikidzana nesimbi pombi matrix. Iyo zinc layer yakatetepa, uye zinc layer inongobatanidzwa nesimbi chubhu matrix uye nyore kudonha. Naizvozvo, kusaita ngura kwayo hakuna kunaka. Muzvivakwa zvitsva zvekugara, zvinorambidzwa kushandisa mapaipi esimbi anotonhora sepombi dzemvura.
