Hot-dip galvanized pipe
Iyo inopisa-dip galvanized pombi ndeyekuita kuti simbi yakanyungudutswa iite nesimbi matrix kuti ibudise alloy layer, kuitira kuti matrix nejasi zvibatane.Kupisa-dip galvanizing ndiko kutanga kutora pombi yesimbi.Kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, inocheneswa mutangi ine ammonium chloride kana zinc chloride aqueous solution kana yakasanganiswa aqueous solution yeammonium chloride uye zinc chloride, yozotumirwa kuIn inopisa dip plating tank.Kupisa-dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.Iyo matrix yepombi inopisa-dip galvanized simbi inosangana nekuita kwakaoma kwemuviri uye kemikari ine yakanyungudutswa yeplating mhinduro kuti igadzire inodzivirira corrosion zinc-iron alloy layer ine compact chimiro.Iyo alloy layer inosanganiswa neiyo yakachena zinc layer uye simbi pombi matrix, saka kushora kwayo kwakasimba.

Pombi inotonhora
Cold galvanized pipe is electro-galvanized, uye uwandu hwegalvanizing iduku zvikuru, chete 10-50g/m2, uye kushorwa kwayo kwekuora kwakasiyana zvakanyanya pane iyo inopisa-dip galvanized pipe.Formal galvanized pombi vagadziri, kuitira kuti vave nechokwadi chemhando, vazhinji vavo havashandisi electro-galvanized (kutonhora plating).Iwo chete mabhizinesi madiki ane zvidiki uye zvechinyakare michina anoshandisa electro-galvanization, uye hongu mitengo yavo yakachipa.Bazi rezvekuvaka razivisa zviri pamutemo kuti mapombi anotonhora ane hunyanzvi hwechinyakare anofanirwa kubviswa, uye mapombi anotonhora haabvumidzwe kushandiswa sepombi dzemvura negasi.Iyo galvanized layer yeinotonhora galvanized simbi pombi is electroplated layer, uye zingi layer inoparadzaniswa nesimbi pombi substrate.Iyo zinc layer yakatetepa, uye zinc layer inongoomerera kune simbi pombi base uye inodonha nyore.Naizvozvo, kusaita ngura kwayo hakuna kunaka.Mudzimba dzichangovakwa, zvinorambidzwa kushandisa pombi dzesimbi dzinotonhora sepombi dzinopa mvura.
