5. Oxidize (dub) los yog QPQ
Kev Kho Mob Nto Hlau QPQ thiab Hlau Stainless
QPQ (Quenched-Polished-Quenched) yog ib txoj kev kho qhov chaw uas ua kom cov hlau thiab stainless hlau zoo dua. Nws muaj ntau yam kauj ruam los txhim kho kev hnav tsis kam, kev tiv thaiv corrosion thiab qhov nyuaj ntawm qhov chaw.
Txheej txheem cej luam:
1. Kev Tua Hluav Taws: Cov khoom ua los ntawm hlau lossis stainless hlau raug cua sov ua ntej kom txog qhov kub thiab txias thiab tom qab ntawd txias sai sai (tso hluav taws) hauv dej ntsev lossis roj. Cov txheej txheem no ua rau cov khoom tawv.
2. Kev txhuam: Qhov saum npoo ces txhuam kom tshem tawm cov oxides thiab txhim kho qhov tiav ntawm qhov chaw.
3. Kev Tua Hluav Taws Thib Ob: Feem ntau cov khoom raug tua dua hauv lwm qhov chaw kom ua rau qhov nyuaj ntxiv thiab tsim ib txheej tiv thaiv.
Qhov Zoo:
-Kev Tiv Thaiv Kev Hnav Zoo Dua: QPQ ua rau qhov kev tiv thaiv kev hnav ntawm cov chaw kho mob zoo dua qub, ua rau nws tsim nyog rau kev siv kev sib txhuam siab.
- Kev Tiv Thaiv Kev Xeb: Cov txheej txheem no tsim cov txheej txheem tiv thaiv tawv uas ua rau muaj kev tiv thaiv kev xeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw ib puag ncig hnyav.
-Qhov Chaw Zoo Dua: Cov kauj ruam polishing ua rau muaj qhov chaw du dua, uas yog qhov zoo rau ob qho tib si zoo nkauj thiab ua haujlwm tau zoo.
-Ua kom tawv dua: Kev kho mob ua rau tawv dua, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom ntev dua.
Qhov Tsis Zoo:
- Tus nqi: Cov txheej txheem QPQ tuaj yeem kim dua li lwm cov kev kho saum npoo vim qhov nyuaj thiab cov khoom siv xav tau.
- Tsuas yog qee cov hlau sib xyaw xwb: Tsis yog txhua qib hlau thiab stainless hlau tsim nyog rau kev ua QPQ; kev sib xws yuav tsum tau soj ntsuam.
- Tej Zaum Yuav Ua Rau Nchuav: Cov txheej txheem cua sov thiab quenching yuav ua rau muaj kev hloov pauv ntawm qhov loj me lossis nchuav hauv qee qhov chaw, uas yuav tsum tau tswj hwm thiab xav txog kev tsim qauv zoo.
QPQ yog ib qho kev kho saum npoo uas muaj txiaj ntsig zoo uas ua rau cov hlau thiab cov hlau tsis xeb ua haujlwm tau zoo dua, tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau kev hnav thiab tiv taus xeb siab. Txawm li cas los xij, tus nqi, kev sib xws ntawm cov khoom siv, thiab qhov ua rau deformation yuav tsum tau xav txog thaum txiav txim siab txog kev kho no.
6. Txheej (piv txwv li hmoov txheej, xim)
- Kev piav qhia: Siv ib txheej tiv thaiv rau ntawm cov hlau tsis xeb.
- qhov zoo dua:
- Muab kev tiv thaiv corrosion ntxiv.
- Muaj ntau yam xim thiab tiav.
- qhov tsis zoo:
- Raws li lub sijhawm dhau mus, cov txheej txheej yuav tawg lossis hnav.
- Tej zaum yuav xav tau kev saib xyuas ntau dua li cov chaw tsis tau kho.
7. Galvanized
- TXHAIS LUS: Txheej nrog ib txheej zinc kom tiv thaiv kev xeb.
- qhov zoo dua:
- Kev tiv thaiv corrosion zoo heev.
- Tus nqi tsim nyog rau cov khoom loj.
- Qhov Tsis Zoo:
- Tsis haum rau cov ntawv thov kub heev.
- Muaj peev xwm hloov qhov tsos ntawm cov hlau tsis xeb.
8. Kev Cim Laser lossis Etching
- KEV PIAV TXOG: Siv lub laser los kos lossis cim cov nto.
- qhov zoo dua:
- Cim ruaj khov thiab meej.
- Tsis muaj kev cuam tshuam rau cov khoom siv.
- qhov tsis zoo:
- Tsuas yog cim xwb; tsis ua rau kom tsis txhob xeb.
- Yuav kim heev rau cov ntawv thov loj.
