Kuonekwa kwehutano hwechigadzirwa chinhu chakakosha chehutano hwekunzwa.Chitarisiko chemhando kazhinji chinoreva hunhu hwechimiro chechigadzirwa, toni yeruvara, kupenya, patani, nezvimwe zvinoonekwa.Zviripachena, hurema hwese senge mabumps, abrasions, indentations, scratches, ngura, mold, mabubbles, pinholes, pitting, kuputika kwepamusoro, delamination, wrinkles, nezvimwe zvichave nemhedzisiro pakuonekwa kwechigadzirwa.Uye zvakare, akawanda emhando yemhando yezvigadzirwa zvekutaridzika anokanganisa zvakananga kuita kwechigadzirwa, hupenyu hwehupenyu, uye zvimwe zvinhu.Zvigadzirwa zvine nzvimbo yakatsetseka zvine simba rekudzivirira ngura, yakaderera friction coefficient, yakanaka kupfeka kuramba, uye kushoma simba rekushandisa.
Kuongororwa kwemhando yechigadzirwa kune imwe subjectivity.Kuti uite mitongo ine chinangwa zvakanyanya sezvinobvira, nzira dzinotevera dzekuongorora dzinowanzo shandiswa mukuongororwa kwemhando yezvigadzirwa zveindasitiri.
(1)Standard muenzaniso boka nzira.Pre sarudza sampuli dzakakwana uye dzisina kukodzera semasampuli akajairwa, uko masampuli asina kukodzera ane hurema hwakasiyana ane madhigirii ekuomarara.
Masampuli akajairwa anogona kudzokororwa kucherechedzwa nevazhinji vaongorori (vaongorori) uye mhedzisiro yekutarisa inogona kuongororwa.Mushure mekuongorora mhedzisiro yenhamba, inogona kutariswa kuti ndeapi akaremara mapoka asina kunyatsotsanangurwa;Ndevapi vaongorori vasina kunzwisisa kwakadzama kwezviyero;Ndevapi vaongorori vasina ruzivo rwakakosha uye kugona kunzwisisa.
(2)Mufananidzo wekutarisa nzira.Kuburikidza nekutora mafoto, chitarisiko chakakodzera uye inotenderwa kuremara miganho inogona kumiririrwa nemifananidzo, uye mapikicha akajairwa eakasiyana-siyana akaremara anogona kushandiswa pakuenzanisa kuongorora.
(3)Defect amplification nzira.Shandisa girazi rinokudza kana purojekita kuti ukure pamusoro pechigadzirwa uye kutsvaga kukanganisa pane inocherechedzwa nzvimbo, kuitira kunyatsoona chimiro uye kuoma kwehurema.
(4)Kunyangarika kureba nzira.Enda kunzvimbo yekushandiswa kwechigadzirwa, ongorora mamiriro ekushandiswa kwechigadzirwa, uye tarisa mamiriro ekushandiswa kwechigadzirwa.Wobva watevedzera iwo chaiwo mashandisirwo echigadzirwa, uye tsanangura inoenderana nguva, yekutarisa kureba, uye kona semamiriro ekutarisa ekuongorora.Kana chimwe chigadzirwa chitarisiko chakaremara chakatsanangurwa, chero bedzi chisingaoneki mukati memasekonzi matatu kubva kure nemamita imwe, chinoonekwa sechakakodzera, kana zvisina kudaro chinoonekwa sechisina kukodzera.Iyi nzira iri nyore uye inoshanda pane kuseta zviyero uye kuita yekuongorora chinhu nechinhu zvichienderana nemhando dzakasiyana uye kuoma kwekuremara kwekutaridzika.
Muenzaniso: Chitarisiko chemhando yekuongorora kwegalvanized coating pane zvikamu.
①Chitarisiko chemhando zvinodiwa.Kutaridzika kwemhando yekupfekedzwa kwemarara kunosanganisira zvinhu zvina: ruvara, kufanana, kukanganisa kunotenderwa, uye hurema husingagamuchirwe.
Color.Semuenzaniso, iyo galvanized layer inofanira kunge iri grey ruvara ine zvishoma beige hue;Mushure mekuratidzwa kuchiedza, galvanized layer inoratidzika sechena yesirivha ine imwe gloss uye zvishoma zvishoma zvebhuruu;Mushure mekurapa phosphate, iyo galvanized layer inofanira kuve yakajeka grey kune sirivheri grey.
Uniformity.Iyo galvanized layer inodiwa kuti ive neyakakwenenzverwa, yunifomu, uye inoenderera pamusoro.
Bvumira kukanganisa.Somuenzaniso, zvishoma mavara emvura;Zvikamu zvakakosha zvikuru, uye pane zvishoma zvigadziriso zviratidzo pamusoro;Pane misiyano mishoma yemuvara uye kupenya pachikamu chimwe chete.
Zvikanganiso hazvibvumirwi.Semuenzaniso: mablister, peeling, kupisa, nodulation, uye pitting of the coating;Dendritic, seponji, uye machira ane mitsetse;Mavara emunyu asina kuchena, nezvimwewo.
②Sampling yekuongorora chitarisiko.Kune zvikamu zvakakosha, zvikamu zvakakosha, zvikamu zvakakura, uye zvikamu zvakajairika zvine saizi isingasviki makumi mapfumbamwe, chitarisiko chinofanira kuongororwa 100% uye zvigadzirwa zvisingaenderane zvinofanirwa kubviswa;Kune zvakajairwa zvikamu zvine saizi yebatch yakakura kupfuura zvidimbu makumi mapfumbamwe, kuongororwa kwesampling kunofanirwa kuitwa, neyakajairwa yekuongorora nhanho yeII uye inokwanisa yemhando yepamusoro ye1.5%.Ongororo yacho inofanirwa kuitwa zvinoenderana neyakajairwa yekuongorora sampling chirongwa chakatsanangurwa muTafura 2-12.Kana batch isina kukodzera yawanikwa, inobvumirwa kuongorora batch 100%, kubvisa zvigadzirwa zvisina kukodzera, uye kutumira zvakare kuti iongororwe.
③Nzira dzekuongorora maitiro uye kuongororwa kwehutano.Kuongorora kwekuona ndiyo nzira huru yekuongorora chitarisiko, uye kana zvichidikanwa, 3-5 nguva yekukudza girazi inogona kushandiswa pakuongorora.Panguva yekuongorora, mwenje wechisikigo wakapararira kana chena mwenje unopfuudzwa pasina ratidziro uchashandiswa, nekuvhenekera kusingasviki mazana matatu lux, uye chinhambwe pakati pezvikamu neziso remunhu chichava 250 millimeters.
Kana saizi yebatch iri zana, saizi yemakumi matatu nembiri inogona kutorwa;Kuburikidza nekutarisa kwekuona kwezvimedu makumi matatu nembiri, zvakaonekwa kuti zviviri zvacho zvaive nemapundu pajira uye mavanga ekutsva.Sezvo nhamba yezvigadzirwa zvisingaenderane zvaive 2, zvakatemwa kuti batch iyi yezvikamu yakanga isingaenderane.
