Maitiro ekuyedza hex bolts

1. Tinowanzotarisa kutaridzika kwemabhaudhinemaziso edu kuona kana electroplated black zinc yemabhaudhi yakanaka, kana paine mavara kana kwete.

2. Kusimba bvunzo yemabhaudhi. Chenesa chidimbu chemafuta panefastenerpamusoro ne peturu kana mumiririri wekuchenesa, inyore mu 3% isina kwairi copper sulfate mvura ye40-60s, uye uione nemeso asina kupfeka mushure mekunge pasina kuteedzera pamusoro.

3. Kuongororwa kwekudzivirira kwehutu hwemabhoti. Chenesa chidimbu cheoiri pane yekusimbisa peturu kana yekuchenesa ajenti, inyudze mu 0.17% sulfuric acid mhinduro ye20-40s, uye uione nemeso asina kupfeka mushure mekunge pasina kuteedzera pamusoro.

4. Pfeka bvunzo dzekudzivisa mabhoti. Chenesa dhizaini yeoiri pane yekumisikidza nepeturu kana yekuchenesa, sungirira chubhu yegirazi ine dhayamita yemukati ye10mm uye kureba kwe500mm yakatwasuka pamusoro pechisungo chekuyereswa, uye nzvimbo yekutarisa yefastener ndeye 45 ° kubva pagirazi chubhu, ine chinhambwe che30mm. Isa funnel pamusoro pechubhu yegirazi, uye woyera 100g yejecha requartz nehukuru hwe 0.5-1.0mm uye makona akapinza. Jecha richadonha zvakasununguka uye rinokanganisa nzvimbo yefastener. Mushure mekuyerera kwejecha, zvinyoro pukuta chisimbiso chepamusoro, Inyura mu 0.5% neutral copper sulfate solution ye30s, ibudise kunze uye uigeze nemvura inoyerera, uye uione nemaziso asina kupfeka.

5. Kucheneswa kwehutano hwekuongorora kwe blackening film yemabhoti. Mushure mokunge chigadziro chasvibiswa uye chacheneswa, uye tisati taponification uye kunyudzwa kwemafuta, donhedza madonhwe 1-2 e10% phenolphthalein alcohol solution pamusoro payo. Kana iyo mhinduro iri pink, inoratidza kuti haina kuchena.

6. Geometric dimension kuongorora. Zvinoenderana nechimiro chechimiro, kudhirowa uye magwaro ekugadzirisa ezvisungo, ongorora nezvishandiso zvinoenderana, makadhi uye maturusi ekuyeresa.

7.Kuongorora huwandu hwemabhaudhi.

① Panguvakugadzirwa kwakawanda, zvitarisiko zvose zvinokosha zvichaongororwa; Kuonekwa kwezvipfeko zvakajairika hazvizove zvisingasviki zvidimbu gumi. Iyo compactness uye yekuchenesa mhando yekuongorora haizove isingasviki 1-3 zvidimbu pabatch.

② Zvese zvisungo zvinogadzirwa mubatch rinotevera kana zvine zvakakosha zvinodiwa zvinozoongororwa; Kana kuti cheki cheki zvinoenderana negwaro rekuita.

③ Kana zvimwe zvinhu mukuongororwa kwesampling zvisina kukodzera, huwandu huchapetwa kaviri kuti aongororwe zvakare. Avo vachiri vasina kukodzera mukuwongororazve vanozobatwa sebasa rekushanda kana kuraswa.
