I. Kev sib txuam meej raws li kev siv Scenarios
Cov kev khiav hauj lwm sib txawv muaj qhov tseem ceeb sib txawv, uas tso cai rau kev sib txuam ncaj qha ntawm cov kev daws teeb meem:
1. Ordinary Indoor Dry Environment: Phosphating + Rust-Inhibiting Oil Application - Tsawg nqi, raws li luv luv -lub sij hawm tiv thaiv xeb thiab machining lubrication xav tau.
2. Sab nraum zoov / Damp ib puag ncig: Kub-Dip Galvanizing - Zinc txheej thickness Ntau dua los yog sib npaug rau 85μm, ntsev tsuag lub neej tshaj 500 teev, ntev -lub sij hawm corrosion kuj.
3. Muaj Corrosive/High-Kev huv huv: Passivation Treatment - Tsim nyog rau cov kav hlau stainless, tsim cov yeeb yaj kiab tiv thaiv ntom ntom, tiv taus chloride ion corrosion.
4. Khoom noj khoom haus / Pharmaceutical/High-Purity Fluid Scenarios: Electrolytic Polishing – Surface roughness Ra<=0.1μm, residue-dawb thiab yooj yim los ntxuav, ua tau raws li cov qauv huv.
5. Ntev-Nyob deb ntawm cov kav xa dej: 3PE / TPEP Anti-Corrosion Txheej - Muaj zog txheej adhesion, kev pab lub neej ntev txog 50 xyoo lossis ntau dua.
II. Zam cov teeb meem ntawm cov khoom siv yeeb nkab
Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv, thiab xaiv cov txheej txheem tsis raug tuaj yeem ua rau cov yeeb nkab ua tau zoo:
1. Carbon steel kav: Galvanizing thiab phosphating yog nyiam vim lawv cov nqi siab dua -effectiveness, tshem tawm qhov yuav tsum tau rau kim passivation.
2. Stainless hlau kav: Acid pickling thiab passivation ua raws li electrolytic polishing yog nyiam kom tsis txhob ua rau corrosion-cov qauv ntawm stainless hlau.
3. Alloy kav: Kub-dip galvanizing ntawm qhov kub siab tshaj 450℃yog txwv tsis pub los tiv thaiv cov nag lossis daus ntawm cov hlau alloying uas tuaj yeem cuam tshuam rau cov khoom siv kho tshuab. Ib qho epoxy zinc-nplua nuj primer + topcoat txheej yog pom zoo.
III. Xav txog kev ua haujlwm tom qab Adaptability
Yog tias cov kav dej yuav raug vuam lossis txiav cov txheej txheem, acid pickling thiab txhaj tshuaj blasting yog qhov zoo dua ua ntej kom tshem tawm cov nplai oxide kom huv si. Qhov no tiv thaiv oxide nplai los ntawm kev ua rau vuam porosity thiab ceev cov cuab yeej hnav los ntawm 3-5 zaug, ua kom cov khoom raug thiab cov khoom tiav tiav.
