1. Peb feem ntau saib cov tsos ntawmcov boltsnrog peb ob lub qhov muag saib seb cov electroplated dub zinc ntawm cov bolts zoo, seb puas muaj pob los yog tsis.
2. Tightness kuaj ntawm bolts. Ntxuav cov roj txheej ntawm lubfastenernto nrog roj av los yog tus neeg saib xyuas tu, tsau nws hauv 3% nruab nrab tooj liab sulfate dej rau 40-60s, thiab saib nws nrog qhov muag liab qab tom qab tsis muaj kab nyob rau saum npoo.
3. Kev tshuaj xyuas ntawm corrosion kuj ntawm bolts. Ntxuav cov roj txheej ntawm lub fastener nto nrog roj av los yog tu tus neeg sawv cev, tsau nws nyob rau hauv 0.17% sulfuric acid tov rau 20-40s, thiab saib nws liab qab qhov muag tom qab tsis muaj ib tug kab nyob rau ntawm qhov chaw.
4. Hnav tsis kam kuaj ntawm bolts. Ntxuav cov roj txheej ntawm lub fastener nto nrog roj av los yog tu tus neeg saib xyuas, dai lub iav raj nrog ib txoj kab uas hla ntawm 10mm thiab ib tug ntev ntawm 500mm vertically saum lub fastener yuav tsum tau ntsuas, thiab qhov chaw soj ntsuam ntawm lub fastener yog 45 ° los ntawm lub iav raj, nrog ib tug deb ntawm 30mm. Nruab ib lub funnel saum lub iav raj, thiab hnyav 100g ntawm quartz xuab zeb nrog ib tug particle loj ntawm 0.5-1.0mm thiab ntse fab. Cov xuab zeb yuav poob dawb thiab cuam tshuam rau qhov chaw fastener. Tom qab cov xuab zeb ntws, maj mam so lub fastener nto, raus hauv 0.5% nruab nrab tooj liab sulfate tov rau 30s, tshem tawm thiab ntxuav nws nrog dej ntws, thiab saib nws nrog liab qab qhov muag.
5. Kev tshuaj xyuas zoo rau blackening zaj duab xis ntawm bolts. Tom qab lub fastener yog blackened thiab ntxuav, thiab ua ntej saponification thiab roj immersion, tee 1-2 tee ntawm 10% phenolphthalein cawv tov rau nws nto. Yog hais tias cov tshuaj yog xim liab, nws qhia tau hais tias nws tsis huv.
6. Geometric dimension soj ntsuam. Raws li cov qauv tsim, kos duab thiab txheej txheem cov ntaub ntawv ntawm fasteners, tshuaj xyuas nrog cov cuab yeej siv, daim npav thiab cov cuab yeej ntsuas.
7.Kev soj ntsuam kom muaj nuj nqis ntawm bolts.
① Lub sijhawmntau lawm, tag nrho cov tshwm sim tseem ceeb yuav tsum raug tshuaj xyuas; Cov tsos ntawm cov fasteners dav dav yuav tsum tsis pub tsawg tshaj 10 daim. Lub compactness thiab tu zoo tshuaj xyuas yuav tsum tsis txhob tsawg tshaj li 1-3 daim ib batch.
② Tag nrho cov fasteners uas tsim nyob rau hauv lub tom ntej no batch los yog nrog tshwj xeeb yuav tsum tau soj ntsuam; Los yog chaw kuaj xyuas raws li cov ntaub ntawv txheej txheem.
③ Yog tias qee yam khoom hauv qhov kev kuaj xyuas tsis tsim nyog, qhov ntau yuav tsum tau muab ob npaug rau kev tshuaj ntsuam xyuas. Cov uas tseem tsis tau tsim nyog nyob rau hauv kev tshuaj ntsuam xyuas yuav tsum raug kho raws li rework lossis scrapping.
