1. Raw khoom npaj: Cov khoom siv raw ntawm cov kav dej steel yog cov kav dej zoo tib yam. Nws yuav tsum tau txiav, polished, thiab lwm yam., kom qhov chaw tiaj tus thiab du, uas yog yooj yim rau kev siv txheej tom ntej.
2. Kev Tu: Ua ntej txheej txheej ntawm cov yeeb nkab steel, nws yog ib qho tsim nyog yuav tsum tshem tawm cov impurities xws li roj, plua plav, thiab ya raws ntawm nws qhov chaw kom ntseeg tau tias qhov adhesion ntawm cov txheej thiab cov nplaim ntawm cov yeeb nkab steel.
3. Kev npaj txheej: Raws li cov txheej txheem sib txawv, cov txheej txheem kev npaj sib txawv, xws li tshuaj tsuag, yaj, thiab lwm yam. Feem ntau hais lus, lub thickness ntawm txheej yuav tsum tau txiav txim siab raws li qhov yuav tsum tau muaj ntawm qhov tshwj xeeb siv ib puag ncig.
4. CICC: Tom qab txheej txheej tau npaj lawm, nws yuav tsum tau kho kom cov khoom siv txheej txheej tsim muaj cov qauv ruaj khov ntawm cov yeeb nkab steel. Cov txheej txheem solidification muaj xws li ntuj solidification, cua sov thiab kho.
5. Kev kuaj xyuas: Tom qab ua cov yeeb nkab steel preservative, yuav tsum tau kuaj xyuas, nrog rau kev kuaj xyuas xws li txheej thickness, uniformity, thiab adhesion. Qhov tsim nyog los tiv thaiv corrosion steel yeeb nkab tuaj yeem muab tso rau hauv kev siv. , Cov kav dej phwj tuaj thiab cov pas dej ua ke lom neeg tiv thaiv kab mob. Agricultural irrigation kav, qhov tob tob, cov kav dej thiab lwm cov tes hauj lwm.
