1, zvinhu zvewaya huru yakabatiswa: zinc ingot: haifanirwe kunge yakaderera pane iyo kwete.- zinc yakatemwa muGB470;Sulfuric acid: giredhi 1 yakadzika sulfuric acid maererano neGB534;Hydrochloric acid: giredhi 1 yakanyanyisa hydrochloric acid maererano neGB534;Ammonium chloride: inofanirwa kuenderana nezvinodiwa zveGB2946 ammonium chloride level 1.
2, chitarisiko: kupfeka kwepamusoro kunoenderera uye kunoshanda, kwakatsetseka;Kuiswa uye kusungirirwa kwezvikamu zvakaputirwa hazvibvumidzwe kuve nekuyerera kwakarembera, kudonha kana kunyungudika.Kumusoro kwezvikamu zvakaputirwa hakuzove nekuremara senge leakage plating uye dova iron, asi kukanganisa kunobvumirwa kuvapo pasi pemamiriro anotevera;Leakage nzvimbo isingasviki 0.5mm dhayamita makwapa;Pasinei nekukura kwechidimbu chekuputira, nzvimbo dziri mudhamu yekuputira nzvimbo ye 0.5mm- Imm dhayamita haifaniri kudarika 3 points per square centimeter, uye nhamba yose yemavara muchidimbu chekuisa haifaniri kudarika 10 points;Mune iyo isiri yekubatanidza kana isiri-junction Angle, kureba kusingapfuuri 1.5mm kuyerera kwakarembera kudonha kana slag;Kune mavanga kana plating zvikamu zvinosangana nemidziyo yekurembera uye maturusi ekushandisa, asi pasina simbi yedova.
3. Zinc adhesion uye zinc layer thickness: kana hupamhi hwezvikamu zvakaputirwa 3mm ~ 4mm, zinc adhesion inofanira kuva isingasviki 460g / m, ndiko kuti, muvhareji wehupamhi hwezinc layer haisi pasi pe65um;Kana hupamhi hwezvikamu zvakaputirwa zvakakura kudarika 4mm, iyo zinc adhesion haifaniri kunge iri pasi pe610g / m, ndiko kuti, muvhareji wehupamhi hwezinc layer haisi pasi pe86um;Coating kufanana,galvanizedlayer iri yunifomu ine copper sulfate solution test etching kashanu pasina dova iron;Coating adhesion, iyo zinc layer yezvikamu zvakaputirwa inofanira kubatanidzwa zvakasimba nesimbi yakakosha ine simba rakakwana rekunamatira, mushure mekuyedza sando kusadonha, kwete convex.
4, kuva plated zvinodiwa: kuti plated pamusoro inofanira kuva yakatsetseka, pasina pickling nzira haigoni kubvisa kusvibiswa, zvakadai mafuta kuverenga, girisi, simende, asphalt uye zvimwe zvinokuvadza tsvina;Mawelds ese enhengo dzakasungwa achanamwa pasina mhepo;Mapombi nemidziyo zvinofanirwa kunge zvine maburi ekuburitsa uye kutora zinc;Iyo workpiece ichapedzwa welded simbi pombi pasina shinda, kana shinda ichadzivirirwa.Muedzo nzira: Zinc adhesion akayerwa nemagineti ukobvu geji uye zinc layer ukobvu hwakayerwa zvakananga.Kufanana kwekupotera kwakatemwa necopper sulfate solution etching test method.
5, nzira yekutambanudza: zinc layer adhesion, zinc layer ukobvu, zinc layer kufanana, adhesion inopokana, tora sampuli uye chigadzirwa pasi pemamiriro akafanana ekuita galvanized;Ita bvunzo, usasangana nezvinodiwa zvechiyero ichi chezvigadzirwa zvisina kukodzera;Chigadzirwa chefekitori sampling bvunzo nzira, kekutanga haizoitike, saka zvinoenderana nezvakakodzera zvigadziro sampling bvunzo, kana ichiri isina kukodzera, tonga iyi batch yezvigadzirwa haina kukodzera.Bhangi remuongorori: Zvikamu zvakapfava zvinokwanisa kunyorwa chete muhofisi inokwanisa mushure mekupihwa chitupa nemuongorori wenguva yakazara;Zvigadzirwa zvinokodzera zvinofanirwa kurongedzerwa zvakatsvinda zvinoenderana neakasiyana zvirevo.
