Pombi yakabatidzwa inopisa

Simbi yakanyungudutswa inosangana nesimbi kuti igadzire alloy layer, kuitira kuti matrix ne coating zvibatanidzwe. Hot dip galvanizing ndeyekutanga kusveta pombi yesimbi, kuitira kubvisa iron oxide pamusoro pepombi yesimbi, mushure mekusveta, kuburikidza ne ammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride mixed aqueous solution tank yekuchenesa, uye wozopinda mu hot dip plating tank. Hot dip galvanizing ine zvakanakira zvekusveta zvakafanana, kunamira kwakasimba uye hupenyu hurefu hwebasa. Mazhinji emaitiro ari kuchamhembe anoshandisa nzira yekudzoreredza zinc ye galvanized belt direct coil pipe.

Pombi yakanyungudutswa inotonhora

Magasi anotonhora anoshandiswa nemagetsi, huwandu hwawo hudiki, 10-50g/m2 chete, ngura yaro yakasiyana zvikuru neipi inopisa. Vagadziri vemapombi anodziya nguva dzose, kuti vave nechokwadi chekuti mhando yacho yakanaka, vazhinji havashandisi magetsi anodziya (cold plating). Mabhizinesi madiki chete ane michina yekare anoshandisa magetsi anodziya, hongu, mitengo yawo yakachipa. Mune ramangwana, mapombi anodziya haatenderwi kushandiswa semapaipi emvura negasi.

Pombi yesimbi yakabatidzwa inopisa

Kusangana kwakaomarara kwemuviri nemakemikari kunoitika pakati pesimbi yesimbi nebhati rakanyungudutswa kuti pave nechikamu chakasimba chezinc-iron alloy chine resistance yengura. Chikamu chealloy chakabatanidzwa ne pure zinc layer uye steel pipe matrix. Saka, kuramba kwayo ngura kwakasimba.

Mushure mekugadzirwa kwepombi dzesimbi dzinopisa dzakabatidzwa muma1960 kusvika kuma1970, mhando yechigadzirwa yakagadziridzwa zvikuru, 1981 kusvika 1989 yakapihwa mubairo weMetallurgical Ministry of High-quality products and National Silver Award, kugadzirwa kwakawedzerawo kwemakore mazhinji, 1993 kuburitsa matani anopfuura 400,000, 1999 kuburitsa matani anopfuura 600,000, uye yakatumirwa kuSoutheast Asia, Africa, United States, Japan, Germany Nyika nenzvimbo. Mapombi emagetsi anopisa anonyanya kushandiswa semapombi emvura nemapombi egasi, uye zvirevo zvakajairika ndezve +12.5~+102 mm. Mushure mema1990, nekuda kwekutarisirwa kwenyika kuchengetedza zvakatipoteredza, kutonga kwemakambani ane kusvibiswa kwakanyanya kuri kuramba kuchinyanya kuoma, "marara matatu" anokonzerwa nekugadzirwa kwemapombi emagetsi anodziya anodziya anodziya akaoma kugadzirisa, pamwe nekukura nekukurumidza kwemapombi esimbi isina ngura, mapaipi ePVC nemapombi emhando yepamusoro, pamwe nekusimudzira kushandiswa kwezvinhu zvekuvaka zvemakemikari, kushandiswa kwemapombi esimbi anodziya kunorambidzwa, zvichiita kuti kukura kwemapombi emagetsi anodziya anodziya anodziya kunokanganiswa zvikuru. Beam nemuganhu, pombi inodziya inodziya inodziya inodziya inodziya inodziya inozokura zvishoma nezvishoma.

Pombi yesimbi inotonhora yakavharidzirwa

Zinc layer yakagadzirwa nemagetsi, uye zinc layer yakazvimisikidza nesimbi pombi matrix. Zinc layer yakatetepa, uye zinc layer yakangobatanidzwa nesimbi pombi matrix uye iri nyore kudonha. Saka, haipindi ngura zvakanaka. Muzvivakwa zvitsva zvekugara, hazvibvumirwi kushandisa mapaipi esimbi anotonhora semapaipi emvura.
