| titleOfInvention | The chrome-plating method and keeping method of a kind of roller |
| abstract | Technical field is maintained the present invention relates to roller, and in particular to the chrome-plating method and keeping method of a kind of roller, the chrome-plating method is：Roller is put into the electroplating bath equipped with chromium plating liquid and electroplated, the chromium plating liquid includes CrO 3 、Cr 3+ 、H 2 SO 4 And additive, wherein, CrO 3 Concentration be 290 310g/L, Cr 3+ Concentration be 2 6g/L, CrO 3 With H 2 SO 4 Weight ratio be 100：1.1 1.2, the concentration of additive is 4 10g/L.The keeping method include clean, dry, oiling, parcel and preservation step.The chromium coating that the chrome-plating method of the present invention is obtained is difficult for drop-off, and technique is simple, convenient operation and control, steady quality, and production efficiency is high, can large-scale industrial production.The keeping method of the present invention can protect the roller will not to corrode and come off, environmental protection, and efficiently, cost is relatively low, easy to operate and safety and stability. |
