Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific embodiments.

[0010] The performance of the rolling oil product after filtering in the present invention is evaluated by using the color change of the rolling oil for one week or two weeks, and the color of the oil is yellow the best and black the worst.

[0011] The filtration effect of the present invention is evaluated by the color change of the filter aid, and is measured according to the percentage of the black filter layer accounting for the height of the entire filter layer. When the filter aid is all black, it is 100%, and the effect is the best, and the filter aid is all off-white. 0%, the worst effect.

[0012] The diatomite used is the RSA700 type produced by Linjiang Xinghui Filter Aid Co., Ltd.; the activated clay is produced by Zhejiang Anji Zhongxin Activated Clay Co., Ltd., and its particle size is 20-80 mesh. Activated carbon was produced by Shanghai Activated Carbon Fa...

Abstract

The invention relates to a filter aid used to rolling oil, wherein said filter aid comprises activate clay and bergmeal at 1:1-3. Compared with present technique, the rolling oil can be filtered completely, with improved oxidation resistance and 50-80% improved application period.

Description

Technical field: [0001] The invention belongs to the technical field of filter aids, in particular to the technical field of copper alloy strip rolling oil filter aids. Background technique: [0002] Copper alloy strip rolling oil is filtered and recovered through a filter. The filter layer of the filter is usually divided into two layers. The lower layer is a filter cloth, which is used to support the filter aid and filter large impurities. The upper layer is a filter aid. It is used for water absorption and decolorization of rolling oil. Commonly used filter aids for rolling oil are diatomite and powdered activated clay or their mixtures. Diatomite has the characteristics of fineness, looseness, light weight, porous, strong water absorption and permeability, and strong adsorption; Activated clay has a wide range of decolorization properties, great decolorization power, strong adsorption and purification power. It is generally believed that the performance of the rolling ...
