Galvanizing inzira yekuisa chivharo chezinc kusimbi kana iron kudzivirira kukoromoka.Iyo nzira inowanzoshandiswa mukugadzira mapaipi, kunyanya ayo anoshandiswa mumaindasitiri akasiyana sekuvaka, mafuta uye gasi, uye mvura.Galvanizing mitemo yepombizvakakosha pakuona kunaka uye kusimba kwepombi dzakagadzirwa nemarara.Ngatinyure mumashoko epombi galvanizing zviyero uye zvavanoreva mumutsetse wepombi galvanizing.
Pombi galvanizingzviyero zvinonyanya kuisirwa neAmerican Society for Testing and Materials (ASTM) sangano repasi rose.ASTM inotemesa zvimiro zvega zvega zvega, izvo zvinosanganisira ukobvu hwemagalvanized layer, kunamatira kwejasi, uye huwandu hwese hwemhando.galvanizedpamusoro.Aya maitiro akakosha kuchengetedza kuvimbika kwepombi yakabatiswa uye kuve nechokwadi chekuita kwayo mumhando dzakasiyana dzekushandisa.
Imwe yeakakosha miyero yemarara pombi ndeyeASTM A123/A123M, iyo inotsanangudza zvinodikanwa zvemabati ekuputira pane zvigadzirwa zvesimbi, kusanganisira mapaipi.Iyi chiyero inotaridza hudiki hwekubatisa ukobvu, kunamatira uye kupedzisa kwepombi yemagetsi.Inopa zvakare nhungamiro yekuongorora uye kuyedzwa kwegalvanized coatingskuve nechokwadi chekutevedzwa kwezviyero.
In pombi galvanizing mitsetse, kutevedzera ASTM A123/A123M zviyero zvakakosha pakugadzira pombi yemhando yepamusoro.Iyo galvanizing process inowanzobatanidza matanho akati wandei, kusanganisira kurapwa kwepamusoro, kupisa-dip galvanizing uye post-kugadzirisa.Imwe neimwe nhanho inofanirwa kutevedzera ASTM zviyero kuti iwane inodiwa yekuputira ukobvu uye mhando.
Kugadzirira kwepamusoro kunosanganisira kuchenesa mapombi kubvisa ngura, chikero kana zvimwe zvinosvibisa zvinogona kudziviriragalvanizinglayer kubva pakunamatira.Iyi nhanho yakakosha kuti uve nechokwadi chekunamatira kwakakodzera kweiyogalvanized coatingkune pombi pamusoro.Iyo inopisa-dip galvanizing process inosanganisira kunyudza pombi dzakacheneswa mubhavhu rezinc yakanyungudutswa, iyo inosungirirana nesimbi kusimbi kuti igadzire coating yekudzivirira..
Mushure mekuita galvanizing, pombi ichaitwa post-processing, iyo inogona kusanganisira quenching, passivation kana kutarisa coating ukobvu uye adhesion.Aya emashure-ekugadzirisa matanho akakosha kuona kuti pombi yakabatiswa inosangana nezvinodiwa zveASTM zviyero uye yakagadzirira kushandiswa mumhando dzakasiyana dzekushandisa.
Kutevedzerapombi galvanizingzviyero hazviiti chete hutano uye kusimba kwepombi, asiwo inobatsira pakuita kwayo kwenguva refu uye kusagadzikana kwemarara.ASTM-inoenderana nemarara pombi inokodzera kunze, hunyoro-hunyoro uye nzvimbo dzinoparadza, zvichiita kuti ive yakanakira maapplication akadai sekugovera mvura, tsigiro yezvimiro uye maindasitiri epombi masisitimu.
Muchidimbu, iyo pombi galvanizing miyero inotsanangurwa neASTM International inoita basa rakakosha mumutsetse wekugadzira pombi.Kutevedzera chiyero ichi kunovimbisa kutigalvanized pipeinosangana nezvinodiwa zvekupfekedza ukobvu, kunamatira uye huwandu hwese.Nekutevera ASTM zviyero,vagadziriinogona kubudisapombi yemhando yepamusoro-galvanizediyo inopa yepamusoro corrosion dziviriro uye hupenyu hwesevhisi mune akasiyana siyana maindasitiri uye ekutengesa maapplication.
