Kuv nrhiav pom "cov roj" stains rau saum npoo ntawm txias - rolled coil ua ntej siv. Kuv yuav tsum ntxuav nws li cas?
Greasy stains (dov cov roj nyob ntawm cov roj hauv qab) {rolled teil yuav tsum tau muab ntxuav kom huv (xws li cov xim txuas ntxiv (xws li cov xim nplaum thiab vuam zoo). Kev tu txoj kev:
Rau lub teeb roj stains: so nrog ib qho chaw ntxhua khaub ncaws (xws li ntxuav tais diav kua) thiab dej, tom qab ntawd yaug nrog cov ntaub huv.
Rau cov roj hnyav stains: siv "degrgeasing tu" (hauv kev siv cov xwm txheej). Siv ib qho kev ua yeeb yam (xws li alkaline degreaser lossis hnyav - Raws li cov dej huv thiab ziab kom xeb los ntawm cov dej noo los ntawm kev noo noo.
NCO TSEG: Tsis txhob siv cov kua qaub muaj zog lossis cov neeg sawv cev alkaline (uas tuaj yeem corrode lub steel saum toj). Tom qab tu, ua cov txheej txheem ua tom ntej lossis xeb kev pab tiv thaiv tsis tau li ntawm 24 teev.

Yuav ua li cas yog ib qho kev xav tau ib puag ncig ntawm txias - rolled coils? Txwv cov khoom muaj kev puas tsuaj puas? Kev tiv thaiv ib puag ncig yuav tsum ua raws thoob ntiaj teb thiab cov kev cai ib puag ncig hauv tsev:
Thoob ntiaj teb: EU RoHS Cov Lus Qhia (txwv rau 6 tus tsiaj muaj kev phom sij:
Domestic: GB / T 26572-2011 "txwv ntawm cov tshuaj txwv hauv cov hluav taws xob thiab khoom siv hluav taws xob" (sib npaug rau RoHs);
Txwv txwv cov tshuaj muaj kev phom sij:
Cov hlau hnyav: txhuas (tsawg dua los yog sib npaug rau 1000ppm), cadmium (tsawg dua lossis sib npaug ntawm 100000ppM);

Daim Ntawv Thov Kev Cai: Cov Khoom Siv Hauv Tsev, Khoom Siv Hluav Taws Xob, Khoom Siv Hluav Taws Xob yuav tsum tau ua tiav cov cai tiv thaiv ib puag ncig; Cov txheej txheem dav dav yuav raug rau ntau qhov kev xav tau.
Kuv tuaj yeem txiav txim dab tsi txawm tias txias -}} rolled coils raws li ib puag ncig cov qauv? Yuav tsum muaj cov ntawv ceeb toom xeem twg? Txoj Kev Txiav Txim:
Tshawb xyuas cov chaw tsim khoom "Ib Cheeb Tsam Kev Ntsuam Xyuas Kev Ntsuam Xyuas" (xws li ROHS lossis mus xeem ntawv). Daim ntawv tshaj tawm no yuav tsum tau tshaj tawm los ntawm ib feem peb -}} kev xeem xeem tog (xws li SGS lossis CTI).
