Precision hydraulic seamless steel kav ua los ntawm precision txias twv tsis xeb hlau kav uas tau ua los ntawm cov txheej txheem dub los yog txho phosphating, thiab cov phosphated steel kav yog ntim thiab xeb-ntawv pov thawj. Sab hauv thiab sab nrauv ntawm cov yeeb nkab steel tsim ua cov phosphate ntom ntom, thiab tom qab kev kho xeb, cov yeeb nkab steel muaj kev tiv thaiv zoo los ntawm oxidation, yog li cov yeeb nkab steel muaj zoo xeb-pov thawj kev ua tau zoo. Nyob rau tib lub sijhawm, microporous phosphate zaj duab xis (txheej) tsim tom qab nplaim ntawm cov yeeb nkab steel tuaj yeem Nws nqus tau cov xim muaj hlau nyob rau saum npoo ntawm cov yeeb nkab steel thiab zoo tiv thaiv cov xim kom tsis txhob poob. Nws yog cov khoom lag luam zoo tshaj plaws rau kev siv hauv thaj chaw ua haujlwm.
