1. Boltsyog ruaj tom qab kub-dip galvanizing: nyob rau hauv suburban ib puag ncig, tus qauv kub-dip galvanized anti-xeb thickness yuav khaws cia rau ntau tshaj 50 xyoo yam tsis tau kho; nyob rau hauv nroog lossis sab ntug dej hiav txwv, cov txheej txheem kub-dip galvanized anti-xeb txheej tuaj yeem khaws cia 20 xyoo yam tsis muaj patching;
2. Tus nqi qis ntawm kev kho kub-dip galvanized ntsia liaj qhov rooj: tus nqi kub-dip galvanized los tiv thaiv xeb yog qis dua li ntawm lwm cov xim pleev xim;
3. Kub-dip galvanized bolts muaj kev ntseeg tau zoo: metallurgical daim ntawv cog lus ntawm txheej galvanized thiab cov khoom siv hlau ua ib feem ntawm cov hlau nto, yog li cov kav ntev ntawm txheej yog ntau txhim khu kev qha;
4. Lub sij hawm-txuag thiab kev txuag hluav taws xob: cov txheej txheem galvanizing sai dua li lwm txoj kev siv txheej txheej, thiab nws tuaj yeem zam lub sijhawm yuav tsum tau pleev xim rau ntawm qhov chaw tsim kho tom qab kev teeb tsa.
5. Lub toughness ntawm txheej yog muaj zog: txheej galvanized tsim ib tug tshwj xeeb metallurgical qauv, uas muaj peev xwm tiv taus txhua yam kev puas tsuaj thaum thauj thiab siv;
6. Kev tiv thaiv zoo: txhua qhov ntawm cov khoom plated tuaj yeem coated nrog zinc, txawm tias nyob rau hauv kev nyuaj siab, cov ces kaum ntse thiab qhov chaw nkaum tuaj yeem tiv thaiv tag nrho;
7. Qhov txiaj ntsig zoo tshaj plaws ntawm kub-dip galvanized bolts yog los txhim kho kev ua haujlwm ntawm cov ntsia hlau.
Kub-dip galvanized ntsia liaj qhov rooj khoom siv:
Cov txheej ntawm kub-dip galvanized bolts yog tuab, feem ntau 30-60 microns, thiab txheej txheej muaj peev xwm tiv thaiv corrosion. Nws yog qhov tsim nyog rau kev tiv thaiv xeb ntev ntev ntawm steel qhov chaw rau kev ua haujlwm sab nraum zoov, xws li cov laj kab kev loj, lub zog yees, qhov loj-loj fasteners thiab lwm yam " ntxhib" workpieces. Cov kav dej hlau ua ntej kuj tau kub-dip galvanized.
Tsis tas li ntawd, vim muaj zog thiab corrosion kuj, kub-dip galvanized bolts yog siv los ua bolts rau lub hwj chim yees, teeb liab yees, thiab txoj kev loj guardrails bolts.
Kub-dip galvanized ntsia liaj qhov rooj zinc txheej tiv thaiv kev ua tau zoo piav qhia:
Feem ntau cov electrogalvanized txheej thickness yog 5 ~ 15μm, thaum kub-dip galvanized ntsia liaj qhov rooj txheej feem ntau yog siab tshaj 35μm, txawm tias siab li 200μm. Kub-dip galvanized bolts muaj kev tiv thaiv zoo, tuab txheej, thiab tsis muaj cov organic suav nrog. Raws li peb txhua tus paub, cov txheej txheem tiv thaiv huab cua ntawm zinc muaj kev tiv thaiv kev tiv thaiv thiab electrochemical tiv thaiv.
Nyob rau hauv atmospheric corrosion tej yam kev mob, muaj ZnO, Zn (OH) 2 thiab yooj yim zinc carbonate tiv thaiv zaj duab xis nyob rau saum npoo ntawm zinc txheej, uas tuaj yeem ua rau qeeb corrosion ntawm zinc rau qee yam. Yog tias cov yeeb yaj kiab tiv thaiv no (tseem hu ua xeb dawb) puas lawm, yuav tsim ib zaj duab xis tshiab. txheej. Thaum cov zinc txheej raug mob hnyav thiab ua rau muaj kev phom sij rau cov hlau substrate, zinc yuav electrochemically tiv thaiv lub substrate,
Tus qauv peev xwm ntawm zinc yog -0,76V, thiab tus qauv peev xwm ntawm hlau yog -0,44V. Thaum zinc thiab hlau tsim lub micro roj teeb, zinc yog yaj raws li anode, thiab hlau tiv thaiv raws li cathode. Obviously, kub-dip galvanized bolts muaj zoo atmospheric corrosion kuj rau lub hauv paus hlau hlau dua electro-galvanized bolts.
