Hot Dip Galvanized Pipe
Iyo inopisa-dip galvanized pombi inobata simbi yakanyungudutswa nesimbi substrate kuti ibudise alloy layer, kuitira kuti substrate uye coating zvibatane.Kupisa-dip galvanizing ndiko kutora pombi yesimbi kutanga.Kuti ubvise iron oxide pamusoro pepombi yesimbi, mushure mekunhonga, inocheneswa neammonium chloride kana zinc chloride aqueous solution kana yakasanganiswa aqueous solution yeammonium chloride uye zinc chloride, yozotumirwa kune inopisa-dip coating tank. .Kupisa-dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.Iyo inopisa-dip galvanized simbi pombi substrate inosangana nemaitiro akaomarara emuviri uye kemikari neyakanyungudutswa yeplating mhinduro kuti iite corrosion-resistant zinc-iron alloy layer ine yakasimba chimiro.Iyo alloy layer inosanganiswa neyakachena zinc layer uye simbi pombi substrate, saka ine yakasimba corrosion resistance.
Kupisa-dhipi kwakakurudzira simbi mapaipi anoshandiswa zvakanyanya mukuvaka, michina, migodhi yemarasha, makemikari, simba remagetsi, njanji mota, indasitiri yemotokari, migwagwa mikuru, mabhiriji, midziyo, nzvimbo dzemitambo, michina yekurima, petroleum michina, michina yekutsvaga, kuvaka greenhouse nezvimwe. maindasitiri ekugadzira.

Cherechedza: Iyo mechanical properties yesimbi chiratidzo chakakosha chekuvimbisa kushandiswa kwekupedzisira kwekushanda (mechanical properties) yesimbi, iyo inoenderana nemakemikari ekuumbwa uye kupisa kwekupisa kwesimbi.Mune simbi pombi zviyero, tensile zvivakwa (tensile simba, goho simba kana goho poindi, elongation), kuoma, kuomarara, uye yakakwirira uye yakaderera tembiricha zvivakwa zvinodiwa nevashandisi zvinotsanangurwa zvinoenderana nezvinodiwa zvakasiyana zvekushandisa.
