Influence of Nonionic Emulsifier on Stability of Cold Rolling Emulsion
TIAN Tian,YAN Feng,ZHU Jing,et al
In the process of producing cold-rolled sheet, the properties of rolling oil,such as lubrication,and emulsion stability are essential factors. This study selected pentaerythrite oleate and mineral from LiaoHe as the base oil. Then adding in diffrernt kinds of nonionic complex emulsifying agent, EP-antiwear additive, antirusting agent, foam suppressor and preservative to the water of 90%~95%, and emulsifying. This experiment used our current industry standard for the reasearch on emulsion stability. The results show that the stability of cold rolling emulsion of the esters and ethers nonionic emulsifier to the base oil is better than a single species of esters or ethers compound system; Final products meet requirements of the emulsion industry standard: After 24 h, 5% emulsion oil separating soap volume is 1.0 mL, 2% emulsion oil the bubbles are completely eliminated in 5 min.
