5. Oxidize (dub) lossis QPQ
QPQ Hlau thiab Stainless Hlau Nto Kho
QPQ (Quenched-Polished-Quenched) yog txheej txheem kho saum npoo uas txhim kho cov khoom ntawm cov hlau thiab stainless hlau. Nws suav nrog ntau cov kauj ruam los txhim kho kev hnav tsis kam, corrosion kuj thiab nto hardness.
Txheej txheem txheej txheem:
1. Quenching: Hlau lossis stainless hlau qhov chaw yog thawj rhuab mus rau ib tug tshwj xeeb kub thiab ces txias txias (quenched) nyob rau hauv ib tug ntsev da dej los yog roj. Cov txheej txheem no hardens cov khoom.
2.Polishing: Qhov saum npoo yog polished kom tshem tawm cov oxides thiab txhim kho qhov chaw tiav.
3. Secondary Quenching: Feem ntau yog quenched dua nyob rau hauv ib tug txawv nruab nrab kom ntxiv hardness thiab tsim ib tug tiv thaiv txheej.
Qhov zoo:
-Txhim kho hnav tsis kam: QPQ txhim kho qhov hnav tsis kam ntawm cov chaw kho mob, ua rau nws tsim nyog rau kev sib txhuam siab.
- Corrosion Resistance: Cov txheej txheem no tsim cov txheej txheem tiv thaiv nyuaj uas txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.
-Txhim kho qhov chaw tiav: Cov kauj ruam polishing ua rau lub ntsej muag smoother, uas muaj txiaj ntsig zoo rau ob qho tib si zoo nkauj thiab ua haujlwm zoo.
-Increase Hardness: Kev kho mob ua kom lub ntsej muag hardness, uas tuaj yeem ua kom ntev kev pab cuam lub neej ntawm cov khoom.
Qhov tsis txaus:
- Tus nqi: Cov txheej txheem QPQ tuaj yeem kim dua li lwm yam kev kho saum npoo vim qhov nyuaj thiab cov khoom siv yuav tsum tau ua.
- Qee cov alloys nkaus xwb: Tsis yog txhua qib steel thiab stainless hlau yog tsim rau QPQ ua; compatibility yuav tsum tau soj ntsuam.
- Muaj peev xwm Warping: Cov txheej txheem cua sov thiab quenching tej zaum yuav ua rau muaj kev hloov pauv lossis kev sib hloov ntawm qee qhov, yuav tsum tau ua tib zoo tswj thiab tsim kev xav.
QPQ yog qhov kev kho mob zoo tshaj plaws uas txhim kho kev ua haujlwm ntawm cov hlau thiab cov hlau tsis muaj steel, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau hnav thiab corrosion kuj. Txawm li cas los xij, tus nqi, cov khoom siv sib raug zoo, thiab muaj peev xwm deformation yuav tsum raug txiav txim siab thaum txiav txim siab txog qhov kev kho no.
6. Txheej (xws li hmoov txheej, xim)
- Nqe lus piav qhia: Siv cov txheej txheem tiv thaiv ntawm cov hlau tsis huv.
- kom zoo dua:
- Muab kev tiv thaiv corrosion ntxiv.
- Muaj nyob rau hauv ntau yam xim thiab tiav.
- shortcomings:
- Sij hawm dhau mus, cov txheej yuav nti los yog hnav tawm.
- Tej zaum yuav xav tau kev saib xyuas ntau dua li qhov chaw tsis kho.
7. Galvanized
- DESCRIPTION: Coated nrog ib txheej ntawm zinc los tiv thaiv corrosion.
- kom zoo dua:
- Zoo heev corrosion kuj.
- Nqi zoo rau qhov loj.
- Qhov tsis txaus:
- Tsis haum rau cov ntawv thov kub.
- Muaj peev xwm hloov cov tsos ntawm stainless hlau.
8. Laser npav lossis Etching
- DESCRIPTION: Siv lub laser los kos lossis kos rau saum npoo.
- kom zoo dua:
- Kev ruaj ntseg thiab meej.
- Tsis muaj kev cuam tshuam rau cov khoom siv.
- shortcomings:
- Kos npe nkaus xwb; tsis txhim kho corrosion kuj.
- Nws tuaj yeem raug nqi rau cov ntawv thov loj.
Hauv kev xaus
Kev xaiv ntawm kev kho deg yog nyob ntawm daim ntawv thov tshwj xeeb, xav tau kev zoo nkauj thiab ib puag ncig. Txhua txoj kev kho mob muaj nws qhov zoo thiab qhov tsis zoo, yog li cov xwm txheej no yuav tsum tau txiav txim siab thaum xaiv txoj kev kho kom haum raustainless hlau ntawv hlau qhov chaw.
