Momwe mungayesere ma bolts a hex

1. Nthawi zambiri timayang'ana maonekedwe amabawutindi maso athu kuona ngati electroplated black zinki wa mabawuti bwino, kaya pali mawanga kapena ayi.

2. Mayeso olimba a mabawuti. Sambani mafuta osanjikiza pamwambachomangirapamwamba ndi petulo kapena woyeretsa, zilowerereni 3% mkuwa sulphate madzi osalowerera ndale kwa 40-60s, ndi kuwona ndi maso amaliseche pambuyo palibe pamwamba.

3. Kuyang'ana kukana kwa dzimbiri kwa mabawuti. Tsukani mafuta osanjikiza pamwamba pa chomangira ndi petulo kapena chotsukira, zilowerereni mu 0,17% sulfuric acid solution kwa 20-40s, ndikuwonetseni ndi maso osawoneka pamwamba.

4. Valani kuyesa kukana kwa mabawuti. Tsukani mafuta osanjikiza pamwamba pa chomangira ndi petulo kapena woyeretsa, ponyani chubu lagalasi ndi mainchesi amkati a 10mm ndi kutalika kwa 500mm molunjika pamwamba pa cholumikizira kuti ayezedwe, ndikuyang'ana pamwamba pa cholumikizira ndi 45 ° kuchokera ku chubu lagalasi, ndi mtunda wa 30mm. Ikani phazi pamwamba pa chubu lagalasi, ndikulemera 100g mchenga wa quartz wokhala ndi tinthu tating'ono 0.5-1.0mm ndi ngodya zakuthwa. Mchenga udzagwa momasuka ndi kukhudza chomangira pamwamba. Mchenga utatha, pukutani pang'onopang'ono chomangira, Imirirani mu 0,5% ya mkuwa wa sulfate osalowerera ndale kwa 30s, itulutseni ndikutsuka ndi madzi oyenda, ndikuwona ndi maso.

5. Kuyeretsa khalidwe kuyendera kwa blackening filimu ya mabawuti. Chomangiracho chikadadetsedwa ndikutsukidwa, ndipo musanamizidwe ndi kumizidwa ndi mafuta, tsitsani madontho 1-2 a 10% phenolphthalein mowa yankho pamwamba pake. Ngati yankho ndi pinki, zimasonyeza kuti si woyera.

6. Kuwunika kwa geometric dimension. Malinga ndi mawonekedwe a structural, zojambula ndi ndondomeko zolemba za fasteners, fufuzani ndi lolingana zida, makadi ndi kuyeza zida.

7.Kuwunika kuchuluka kwa mabawuti.

① Pa nthawikupanga zochuluka, mawonekedwe onse ofunikira ayenera kuyang'aniridwa; Maonekedwe a fasteners ambiri sadzakhala osachepera 10 zidutswa. Kuyang'ana kowoneka bwino komanso kuyeretsa sikuyenera kuchepera 1-3 zidutswa pa batch.

② Zomangira zonse zopangidwa mugulu lotsatira kapena zofunikira zapadera ziyenera kuyang'aniridwa; Kapena fufuzani malo molingana ndi zikalata zamachitidwe.

③ Ngati zinthu zina pakuwunika kwachitsanzo ndizosayenerera, kuchuluka kwake kudzachulukidwa kawiri kuti awonedwenso. Omwe sanayenerere pakuwunikanso adzatengedwa ngati kukonzanso kapena kuchotsedwa.
