Cov ntawv txias-dov hlau tuaj yeem raug kho qhov sib txawv thaum lub sijhawm tsim khoom los txhim kho lawv cov tsos, kev tiv thaiv corrosion thiab lwm yam ntxwv. Cov hauv qab no yog cov kev kho mob khaub thuas-kuav los tiag steel phaj nto:
Pickling: Pickling suav nrog cov hlau phaj hauv cov kua qaub kom tshem tawm cov oxidation saum npoo, xeb, thiab lwm yam kab mob. Qhov no tuaj yeem txhim kho qhov zoo ntawm cov phaj steel thiab muab cov substrate huv si rau kev kho mob tom ntej.
Txheej: Cov ntawv txias-dov steel tuaj yeem coated kom lawv cov corrosion kuj thiab kev zoo nkauj. Cov txheej txheem muaj xws li zinc txheej (galvanizing), pleev xim, txheej yas, thiab lwm yam. Zinc txheej tuaj yeem muab kev tiv thaiv corrosion zoo heev, thaum pleev xim lossis plastering tuaj yeem ua rau kom pom thiab oxidation tsis kam ntawm qhov chaw.
Galvanizing: Galvanizing suav nrog cov hlau phaj hauv cov zinc yaj los tsim cov zinc txheej ntawm qhov chaw. Cov txheej no muab kev tiv thaiv corrosion zoo heev thiab feem ntau siv rau hauv cov ntawv thov uas nws raug rau qhov chaw ntub dej lossis corrosive ib puag ncig.
Phosphating: Phosphating yog tsau cov hlau phaj hauv cov tshuaj uas muaj phosphate los ua ib zaj duab xis phosphating. Cov yeeb yaj kiab no tuaj yeem muab qee qhov kev tiv thaiv corrosion thiab muab cov adhesion zoo dua rau kev kho mob tom ntej xws li pleev xim.
Polishing: Polishing yog polishing nto ntawm steel phaj los ntawm kev ua txhua yam kom tau ib tug du thiab ci nto. Qhov no feem ntau yog siv rau hauv cov ntawv thov uas xav tau qib siab ntawm cov tsos.
Sandblasting: Sandblasting yog txau cov khoom abrasive rau saum npoo ntawm cov hlau phaj ntawm kev kub ceev kom tshem tawm cov oxides, av, thiab lwm yam, thaum tsim cov nyhuv frosting, uas feem ntau yog siv hauv kev kho kom zoo nkauj thiab lwm yam.
Polishing: Los ntawm kev kho tshuaj los yog kev siv tshuab ua kom lub ntsej muag ntawm cov phaj steel ntau du thiab ci, feem ntau siv rau hauv qee qhov kev siv uas xav tau kev cuam tshuam lub teeb.
