Reasonable control of double zero aluminum foil rolling oil filtration accuracy

2017/8/1 16:04:19

From the following aspects to a reasonable control of rolling oil filtration accuracy, to ensure good results:

First, according to a reasonable proportion of active clay and diatomaceous earth. Whether with the appropriate proportion of active clay and diatomaceous earth, will directly affect the rolling oil filtration accuracy and the use of rolling oil for a long time. In the filtration of rolling oil, which diatomaceous earth similar to the sieve, can play the role of skeleton, you can filter large particles, you can always keep the filter cake through the state. Activated clay with a certain polarity, can absorb trace moisture, small particles, oxides. In the filter house rolling oil, the need to rational use of different sizes of two kinds of particles of activated clay and diatomaceous earth, according to the ratio of 2: 1: 1 to deploy. Pre-coating process need to add a certain amount of diatomaceous earth, and then enough to join the activated clay, can be appropriate to improve the filtration effect, with no more than 0.1% of the amount of ash.

Second, the regular replacement filter cloth. In the rolling of the waiting, the need for a reasonable replacement of filter cloth, to avoid contamination of the oil, to ensure that the formation of white bars.

Third, the provisions of personal management. Regularly add a certain amount of filter aid, timely replacement filter cloth, to record, to ensure that the rolling oil filtration accuracy.

2 concluding remarks

All in all, in the analysis of double zero aluminum foil pinhole causes and quality control path selection, the need to consider a variety of factors to ensure quality.
