Described a kind of rolling metal ROLLING OIL filter aid, is characterized in that, the particle diameter of described cellulose filter aid is 40-500 μm.
Inventor thinks and meets rolling metal ROLLING OIL filtering requirement, filter aid need have absorption crown_interception to metal impurities in ROLLING OIL, select the filter aid that proportion is little, absorption ROLLING OIL is few simultaneously, then can realize reducing filter aid consumption, reduce the requirement that ROLLING OIL filters loss.
In recent years; along with the filtering requirement constantly updated attention and the adaptation of environmental protection; the cellulose filter aid prepared by plant biomass material (natural plants such as timber, stalk, cotton), the new type filter aid as organic environmental-protection has more and more been paid attention to and has been used.
Inventor thinks that cellulose filter aid is organic material, and proportion is little, and quality is light, the filtering layer of same thickness, and its consumption is much smaller than diatomite and atlapulgite; The hydrophilic not close oil properties of cellulose drainage itself, makes it not strong to the absorption of ROLLING OIL; Through the cellulose filter aid of specially treated, there is suitable particle diameter, the impurity particle adsorbed in ROLLING OIL can be retained; Cellulose filter aid material has elasticity, and in filter process, formed and have compressible filter cake, can keep high porosity in a long time, maintain very fast filtering velocity, filter cycle extends.
The present invention compared with prior art, the cellulose filter aid used, through special process, metal impurities particle in ROLLING OIL can be adsorbed, filter cycle at least extends 3 times on year-on-year basis, and the ratio that ROLLING OIL is filtered is original cleaner, limpid in sight, and the total consumption of filter aid reduces, filter aid adsorbs the rolling oil mass taken away to be reduced, and the solid waste total amount produced after filtering reduces.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, can implement according to this with reference to description word to make those skilled in the art.
