1. Sidla ngokujonga inkangeleko yeiibholitingamehlo ethu ukubona ukuba i-zinc emnyama ye-electroplated yeebholithi ilungile, nokuba kukho amabala okanye akukho.
2. Uvavanyo lokuqina kweebholithi. Coca umaleko oyile kwiisiqhoboshiumphezulu ngepetroli okanye i-agent yokucoca, yifake kwi-3% ye-copper sulfate engathathi hlangothi yamanzi kwi-40-60s, kwaye uyigcine ngamehlo enyama emva kokuba kungabikho mkhondo phezu komhlaba.
3. Ukuhlolwa kwe-corrosion resistance of bolts. Coca i-oyile kwi-fastener surface nge-petroli okanye i-arhente yokucoca, yifake kwi-0.17% isisombululo se-sulfuric acid ye-20-40s, kwaye uyigcine ngamehlo emva kokuba kungabikho mkhondo ebusweni.
4. Gqoka uvavanyo lokumelana neebholiti. Coca i-oyile kwi-fastener surface nge-petroli okanye i-agent yokucoca, xhoma ityhubhu yeglasi kunye nobubanzi bangaphakathi be-10mm kunye nobude be-500mm ngokuthe nkqo ngaphezu kwe-fastener ukuba ilinganiswe, kunye nokuhlolwa kwendawo yokudibanisa i-45 ° ukusuka kwi-tube yeglasi, kunye nomgama we-30mm. Faka i-funnel ngaphezu kwe-tube yeglasi, kwaye ulinganise i-100g yesanti ye-quartz kunye ne-particle ye-0.5-1.0mm kunye neekona ezibukhali. Isanti iya kuwa ngokukhululekileyo kwaye ichaphazele i-fastener surface. Emva kokuba isanti igeleza, sula ngobunono umphezulu we-fastener, Gxila kwi-0.5% yesisombululo se-copper sulfate engathathi hlangothi kwiminyaka engama-30, yikhuphe kwaye uyihlambe ngamanzi aqukuqelayo, kwaye uyiqwalasele ngamehlo.
5. Ukucoca umgangatho wokuhlolwa kwefilimu emnyama yeebholithi. Emva kokuba i-fastener ibe mnyama kwaye ihlanjululwe, kwaye ngaphambi kokuba i-saponification kunye nokucwiliswa kweoli, yehla i-1-2 yehla ye-10% ye-phenolphthalein isisombululo sotywala kumphezulu wayo. Ukuba isisombululo sipinki, sibonisa ukuba asicocekanga.
6. Ukuhlolwa komlinganiselo wejometri. Ngokwemilo yesakhiwo, imizobo kunye namaxwebhu enkqubo ye-fasteners, hlola ngezixhobo ezihambelanayo, amakhadi kunye nezixhobo zokulinganisa.
7.Ubungakanani bokuhlolwa kweebholithi.
① Ngexeshaimveliso enkulu, yonke inkangeleko ebalulekileyo iya kuhlolwa; Ukubonakala kwee-fasteners eziqhelekileyo akuyi kuba ngaphantsi kweengcezu ezili-10. Ukuxinwa kunye nokuhlolwa komgangatho wokucoca akuyi kuba ngaphantsi kweengcezu ezi-1-3 kwibhetshi nganye.
② Zonke iziqhoboshi eziveliswe kwibhetshi elandelayo okanye ezineemfuno ezizodwa ziya kuhlolwa; Okanye khangela ibala ngokwamaxwebhu enkqubo.
③ Ukuba ezinye izinto kuhlolo lwesampulu azifaneleki, ubungakanani buphindwe kabini ukuze buphinde buhlolwe. Abo bangekaqinisekiswa kuhlolo ngokutsha baya kuthathwa njengokuphinda kusetyenziswe okanye ukuchithwa.
