Nyob rau hauv lub tshav pob ntawm niaj hnub precision hardware manufacturing, corrosion kuj thiab zoo li zoo ntawm fasteners ncaj qha cuam tshuam rau lub neej kev pab cuam thiab kev cia siab ntawm cov khoom kawg. Knurled xauv ceev, ua los ntawm tooj dag, yog dav siv nyob rau hauv kev lag luam vim lawv zoo heev lub cev thiab txhua yam khoom xws li thermal conductivity, hluav taws xob conductivity, thiab dov zog. Txawm li cas los xij, tooj dag yog qhov cuam tshuam rau oxidation thiab discoloration nyob rau hauv lub ntuj huab cua, uas qhov chaw siab xav tau kev kho deg txheej txheem. Txhawm rau tiv thaiv kom tsis txhob xeb ntawm cov fasteners no, kev lag luam feem ntau siv kev sib xyaw ntawm cov tshuaj polishing thiab passivation deg kev kho mob rau ntau yam knurled ceev kom ua tiav lawv cov kev tiv thaiv corrosion thiab nto tiav.
Tom qab knurled xauv ceev yog machined, nto feem ntau khaws oxides, burrs, thiab ntau yam kab mob. Yog li ntawd, pretreatment nrog ib puag ncig tus phooj ywg thiab universal tooj dag tshuaj polishing tov yog qhov tseem ceeb. Cov tshuaj polishing no tuaj yeem sai thiab maj mam tshem tawm cov impurities saum npoo yam tsis ua rau corrosion ntau dhau los yog pitting. Nyob rau hauv kev xyaum, immersion nyob rau hauv chav tsev kub li ntawm 15 vib nas this feem ntau yog txaus los kho cov knurled tooj dag txiv ntseej mus rau ib tug du luster, nthuav ib tug ci golden xim thiab ua kom tiav ib lub hom phiaj - tshiab pom nyhuv, nteg lub hauv paus ruaj khov rau tom qab xeb tiv thaiv kev kho mob.
After chemical polishing and thorough cleaning, the workpiece must undergo rust prevention treatment to form a dense passivation film on the surface. Cov txheej txheem passivation yog qhov yooj yim; Tsuas yog muab cov tooj liab ntxuav hauv ib qho kev mob siab rau tooj liab passivation tov rau li 15 feeb. Qhov zoo tshaj plaws ntawm cov txheej txheem passivation no yog tias nws tsis hloov qhov loj me lossis cov tsos ntawm lub workpiece, thiab tsis cuam tshuam rau nws cov hluav taws xob conductivity. Yog li ntawd, rau kelly ntxig txiv ntseej yuav tsum tau siab precision, qhov kev kho mob passivation no yog ib qho kev xaiv zoo tshaj plaws rau inter- txheej txheem xeb tiv thaiv thiab corrosion inhibition ntawm cov khoom kawg.
Ntxiv nrog rau cov txheej txheem tshuaj polishing thiab passivation, txoj kev tiv thaiv lub cev tuaj yeem siv los txhim kho kev tiv thaiv xeb rau qee qhov tshwj xeeb. Piv txwv li, qee lub tuam txhab kho vajtse tsim cov qauv tsim nrog lub tes tsho tiv thaiv uas haum nruj rau sab saum toj thiab sab nraud ntawm cov khoom ua haujlwm, tiv thaiv kom tsis txhob ya raws los ntawm kev nkag mus rau hauv lub qhov threaded. Cov dej noo tshiab no-cov ntaub ntawv pov thawj tsim tau zoo txhim kho tag nrho cov sealing thiab noo noo- pov thawj kev ua tau zoo ntawm kelly ntiv tes xoo, uas nquag raug rau qhov chaw ntub dej, ua rau lawv lub neej ua haujlwm ntev.
Hauv cov ntawv thov kev lag luam, cov kev cai rau kev tiv thaiv xeb sib txawv nyob ntawm cov khoom siv fastener. Piv nrog rau cov tooj liab ntshiab, qee cov khoom sib txuas uas muaj hlau muaj ntau dua rau electrochemical corrosion. Yog li ntawd, thaum kho kelly steel txiv ntseej, ntxiv rau kev tiv thaiv kab mob tiv thaiv xeb, phosphating, blackening, lossis electroplating txheej txheem qee zaum yuav tsum tau tsim cov yeeb yaj kiab tiv thaiv zoo dua. Rau knurled cap txiv ntoo ua los ntawm cov tooj liab ntshiab, kev tsom mus rau kev khaws cia lawv cov xim ntuj thiab kev coj ua; passivation yog undoubtedly qhov kev daws teeb meem zoo tshaj plaws, ntsuas kev zoo nkauj thiab kev tiv thaiv.
Tsis tas li ntawd, qhov chaw cia khoom thiab kev saib xyuas txhua hnub yog qhov tseem ceeb rau kev tiv thaiv cov txiv ntoo tooj liab los ntawm xeb. Cov khoom siv tooj dag yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, thiab qhov kub thiab txias -tswj ib puag ncig, nrog cov av noo nyob hauv qab 50%. Thaum ntim khoom, tsis txhob siv cov hnab yas zoo tib yam uas tsis ua pa thiab yooj yim ntxiab ya raws; Nws raug nquahu kom siv cov tshuaj tiv thaiv - oxidation daim ntaub, ntawv, los yog tso silica gel desiccants rau hauv. Rau cov noob txiv ntoo uas nyuaj, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag nrog sulfur- muaj cov roj hmab los yog cov kua qaub kom tiv thaiv kom tsis txhob muaj oxidation thiab tawg.
Kev tuav kom zoo thaum lub sij hawm sib dhos thiab siv tau tuaj yeem ua rau qeeb rusting. Thaum lub sij hawm installation, xyuas kom meej tias ob txhais tes huv si thiab qhuav kom tsis txhob muaj chloride ions thiab lactic acid los ntawm hws los ntawm kev ua tus ntiv tes-zoo li xeb ntawm qhov chaw ua haujlwm. Rau kelly bolted txiv ntseej uas yuav tsum tau tiv taus siab torque, nws raug nquahu kom siv cov cuab yeej tsim nyog thiab siv qhov tseeb torque teeb tsa kom tsis txhob muaj kev puas tsuaj rau cov xov thiab cuam tshuam ntawm qhov chaw passivation zaj duab xis. Kev tshuaj xyuas thiab tu cov khib nyiab tsis tu ncua los ntawm cov xov kuj zoo tswj lawv cov xeb-cov khoom tiv taus.
Rau cov fasteners uas yuav tsum tau ntev - lub sij hawm cia los yog ua hauj lwm nyob rau hauv hnyav tej yam kev mob, xeb- roj tiv thaiv yuav raug txiav txim siab rau kev tiv thaiv ntxiv. Nyob ntawm lub sijhawm ntawm lub sijhawm tiv thaiv xeb, nyias - zaj duab xis lossis tawv - zaj duab xis xeb- cov roj tiv thaiv tuaj yeem xaiv tau. Nyob rau hauv ib puag ncig marine los yog siab - ntsev- cov tshuaj tsuag, siv lub zog - zaj duab xis xeb- tiv thaiv cov roj rau kelly bolted txiv ntseej muab kev tiv thaiv ntev dua -. Rau luv luv-lub sij hawm xeb tiv thaiv ntawm cov txheej txheem, yooj yim-rau- ntxuav tawm- hom xeb- cov roj tiv thaiv tuaj yeem siv los ua kom zoo tom qab machining.
