Kuonekwa kwehutano hwechigadzirwa chinhu chakakosha chehutano hwekunzwa. Chitarisiko chemhando kazhinji chinoreva hunhu hwechigadzirwa chimiro, toni yeruvara, gloss, pateni, nezvimwe zvinoonekwa zvinoonekwa. Zviripachena, hurema hwese senge mabumps, abrasions, indentations, scratches, rust, mildew, mabubbles, pinholes, magomba, kuputika kwepasi, layering, uye wrinkles zvinokanganisa kutaridzika kwechigadzirwa. Uye zvakare, akawanda ecosmetic chigadzirwa mhando zvinhu zvakare zvinokanganisa zvakananga kuita kwechigadzirwa, hupenyu uye zvimwe zvinhu. Semuenzaniso, zvigadzirwa zvine nzvimbo yakatsetseka zvine simba rekudzivirira ngura, diki friction coefficient, yakanaka kupfeka kuramba uye kuderera kwesimba rekushandisa. Kuongororwa kwemhando yechigadzirwa kune imwe subjectivity. Kuti uite mutongo une chinangwa zvakanyanya sezvinobvira, nzira dzinotevera dzekuongorora dzinowanzo shandiswa mukuongororwa kwemhando yezvigadzirwa zvemaindasitiri.
(1) Standard muenzaniso boka nzira. Iwo akakodzera uye asina kukodzera samples anosarudzwa zvakateerana seakajairwa masampuli pamberi, umo iwo asina kukodzera samples ari akasiyana akaremara nekuomarara kwakasiyana. Sampuli dzakajairwa dzinogona kudzokororwa kucherechedzwa nevazhinji vaongorori (vaongorori), uye zvinoonekwa zvinogona kuverengerwa. Mushure mekuongorora mhedzisiro yenhamba, zvinokwanisika kuziva kuti ndeapi akaremara mapoka akatsanangurwa zvisina kufanira; izvo vaongorori vasina kunzwisisa kwakadzama kwechiyero; izvo vaongorori vanoshaya kudzidziswa kunodiwa uye kusarura. (2) Mufananidzo wekutarisa nzira. Kuburikidza nekutora mafoto, chitarisiko chakakodzera uye muganho unotenderwa wehurema unoratidzwa nemifananidzo, uye mapikicha akajairwa ezvakasiyana zvisingabvumirwe kuremara anogona zvakare kushandiswa seyekuenzanisa bvunzo. (3) Kuremara nzira. Shandisa girazi rinokudza kana purojekita kukudza pamusoro pechigadzirwa uye tarisa zvikanganiso pane inocherechedzwa kuti unyatso kutonga chimiro uye kuoma kwehurema. (4) Kutsakatika daro nzira. Enda kunzvimbo yekushandisa chigadzirwa, ongorora mamiriro ekushandisa echigadzirwa, uye tarisa mamiriro ekushandiswa kwechigadzirwa. Zvadaro tevedzera mamiriro chaiwo ekushandiswa kwechigadzirwa, uye tsanangura nguva inoenderana, nzvimbo yekucherechedza uye kona semamiriro ekucherechedza panguva yekuongorora. Inotongwa sechigadzirwa chakakodzera, kana zvisina kudaro chiri chigadzirwa chisina kukodzera. Iyi nzira iri nyore uye inoshanda pane kugadzira zviyero uye kuongorora chinhu nechinhu zvinoenderana nemhando dzakasiyana dzehurema hwekutaridzika uye kuomarara kwakasiyana.
Muenzaniso: Chitarisiko chemhando yekuongorora kwegalvanized layer yezvikamu.
①Chitarisiko chemhando zvinodiwa.Kutaridzika kwemhando yegalvanized layer inosanganisira zvinhu zvina: ruvara, kufanana, kukanganisa kunobvumirwa uye kukanganisa kunobvumirwa. color. Semuenzaniso, iyo galvanized layer inofanirwa kuve yakajeka grey ine beige shoma; iyo galvanized layer inofanira kunge iri sirivheri-chena ine imwe inopenya uye yakajeka yebhuruu mushure mekubuda kwechiedza; mushure mekurapa phosphate, iyo galvanized layer inofanirwa kuve yakajeka grey kune sirivheri grey. kufanana. Iyo galvanized layer inodiwa kuti ive yakanaka-grained, yunifomu uye inoenderera mberi. Kukanganisa kunobvumirwa. Zvakadai se: mavanga emvura zvishoma; zvidiki zvigadziriso mamakisi pane akakosha zvakanyanya ezvikamu; misiyano midiki yemuvara uye gloss pachikamu chimwe chete, etc. Kukanganisa hakubvumirwi. Zvakadai se: kuvhara mablistering, peeling, kupisa, nodules uye pitting; dendritic, spongy uye streaky coatings; maronda emunyu asina kugezwa, nezvimwewo.
②Sampling yekuongorora chitarisiko.
Kune zvikamu zvakakosha, zvikamu zvakakosha, zvikamu zvakakura uye zvikamu zvakajairika zvine batch saizi isingasviki 90 zvidimbu, chitarisiko chinofanira kuongororwa 100%, uye zvigadzirwa zvisina kukodzera hazvifanirwe kuverengerwa; kune zvakajairwa zvidimbu zvine batch saizi inodarika zvidimbu makumi mapfumbamwe, kuongororwa kwesampling kunofanirwa kutorwa, kazhinji kutora nhanho yekuongorora II, inokodzera Iyo yemhando yepamusoro i1.5%, uye kuongororwa kunoitwa zvinoenderana neiyo-yenguva-sampling chirongwa cheyakajairwa kuongororwa. zvinotsanangurwa muTable 2-12. Kana batch yepasi yawanikwa, inotenderwa kuongorora batch 100%, kuramba chigadzirwa chepasi, uye kuchiendesa zvakare kuti chiongororwe.
③Chitarisiko chekuongorora nzira uye kuongororwa kwehutano.
Kuongorora kwekuona kunonyanya kuenderana nekuona nzira. Kana zvichidikanwa, inogona kuongororwa negirazi rinokudza 3 kusvika ku5 nguva. Panguva yekuongorora, shandisa mwenje wakasarudzika wakasarudzika kana chena unopfuudzwa mwenje usina kuratidzwa chiedza, mwenje hausi pasi pe300 lux, uye chinhambwe pakati pechikamu uye ziso remunhu 250 mm. Kana batch iri zana, saizi yemuenzaniso inogona kutorwa zvidimbu makumi matatu nemaviri; kuburikidza nekutarisa kwekuona kwezvimedu makumi matatu nembiri, zvinoonekwa kuti maviri acho ane blistered coating uye scorch marks. Sezvo nhamba yezvigadzirwa zvisina kukodzera ndeye 2, inotongwa kuti batch yezvikamu haina kukodzera.
