Kev kho saum npoo ntawm ob lub taub hau bolts yog tsuas yog los txhim kho lawv cov corrosion kuj thiab hnav tsis kam. Cov txheej txheem kho saum npoo muaj xws li galvanizing, chromium plating, npib tsib xee plating, kho cua sov, nitriding, thiab lwm yam.
1. Galvanizing: Qhov no yog txoj kev kho saum npoo uas muaj peev xwm muab tau zoo corrosion kuj thiab feem ntau yog siv rau sab nraum zoov ib puag ncig.
2. Chromium plating: Chromium plating tuaj yeem muab cov tawv tawv zoo heev thiab hnav tsis kam, feem ntau yog siv rau kev siv zog siab.
3. Nickel plating: Nickel plating tuaj yeem muab kev tiv thaiv corrosion zoo thiab zoo li qub, feem ntau yog siv rau cov khoom siv kho kom zoo nkauj.
4. Kev kho cua sov: Kev kho cua sov tuaj yeem hloov qhov hardness thiab toughness ntawmbolts, txhim kho lawv lub zog tensile thiab hnav tsis kam.
5. Nitriding: Nitriding tuaj yeem txhim kho corrosion kuj thiab hnav tsis kam ntawm bolts, feem ntau yog siv nyob rau hauv high-temperature thiab corrosive ib puag ncig.
Kev paub txog kev kho ntawm ob lub taub hau bolts:
1. Tsis txhob sib cuag ntawm studs thiab corrosive yam xws li acids, alkalis, thiab lwm yam.
2. Tsis tu ncua ntxuav lub stud bolts kom tshem tawm cov plua plav thiab av ntawm qhov chaw.
Thaum siv ob lub taub hau bolts, nruj nruj yuav tsum raug zam kom tsis txhob deformation lossis tawg ntawmbolts.
Thaum khaws cov studs, lawv yuav tsum tau muab tso rau hauv qhov chaw qhuav thiab qhov cua kom tsis txhob ya raws corrosion.
Yog tias xeb pom ntawm ob lub taub hau bolts, xeb tshem tawm yuav tsum tau siv tam sim ntawd los ntxuav.
Thaum hloov ob lub taub hau bolts, cov kev qhia tshwj xeeb thiab cov qauv uas phim cov bolts thawj yuav tsum raug xaiv los xyuas kom meej qhov ruaj khov ntawm kev sib txuas.
