1、膜厚不够：处理的方法是查验阳端氧化工艺是不是标准，看温度，工作电压，导电性等要素是不是平稳，若有出现异常，请相对调节标准之，如果没有出现异常，可适度增加空气氧化时间，确保膜厚合格。
1. Insufficient film thickness: the treatment method is to check whether the oxidation process at the positive end is standard and whether the temperature, working voltage, conductivity and other factors are stable. If there is any abnormality, please adjust the standard relatively. If there is no abnormality, the air oxidation time can be increased appropriately to ensure that the film thickness is qualified.
2、染液ph值太高：这时，能用冰醋酸将ph值调为标准值。
2. The pH value of dyeing solution is too high: at this time, the pH value can be adjusted to the standard value with glacial acetic acid.

3、空气氧化后钢件在不锈钢水槽中置放时间长时间：倡导立即染色剂，假如这种情况早已产生，可将钢件放到阳端处理槽中或氰化钠中合槽中适度解决后再开展染色剂，实际效果会非常好。
3. After air oxidation, the steel parts are placed in the stainless steel tank for a long time: it is advocated to immediately dye. If this situation has already occurred, the steel parts can be put into the positive end treatment tank or sodium cyanide joint tank for appropriate solution, and then carry out the dye. The actual effect will be very good.
4、采用染剂已溶解或发霉：这时需拆换染剂，采用适合染剂。
4. The dye has been dissolved or moldy: at this time, it is necessary to remove and replace the dye and use a suitable dye.
5、空气氧化温度过低，造成皮膜高密度：可适度提升空气氧化温度。
5. The air oxidation temperature is too low, resulting in high film density: it can moderately increase the air oxidation temperature.
6、导电性欠佳：将会阳端铜杆或负端铅板松动图示大批量导电性欠佳。留意清理阳端铜杆及负端铅板，确保导电性。
6. Poor conductivity: the copper rod at the positive end or the lead plate at the negative end will be loose. As shown in the figure, the conductivity of a large number is poor. Pay attention to cleaning the copper rod at the positive end and the lead plate at the negative end to ensure excellent conductivity.
