铝材加工中抑制水基润滑冷却液腐蚀现象的研究

STULY ON CONTROLLING CORROSION BY A WATERBASE LUBRICANT COOLING LIQUID IN ALUMINIUM PRODUCT PROCESSING

对在铝材加工中水基润滑冷却液使铝产生腐蚀的原因进行了探讨，提出了控制酸度为７～９的方法可抑制铝腐蚀．选用不饱和酯肪酸为缓冲剂。

The authors made an approach to the causes of aluminium corrosion by a waterbase lubricnt cooling liquid used in a luminium product processing, and put forward a method to control aluminium corrosion by keeping the acidity range of pH 7～9 and adding unsaturated fatty acid (about 5 % Wt concentration) as a buffer.
