Abstract
A magnetorheological material that includes magnetic particles; at least one water-soluble suspending agent selected from the group consisting of cellulose ether and biosynthetic gum; and water. The material can have a high particle loading, minimizes waste disposal problems, and can be produced at a lower cost relative to magnetorheological materials that include hydrophobic-oil type fluids as a carrier fluid.
Claims25
A magnetorheological fluid comprising magnetic particles;
- at least one biosynthetic gum;
- and water.
A magnetorheological fluid comprising magnetic particles;
- a carrier component for the magnetic particles comprising water;
- and 0.1 to 2 weight percent (based on the total weight of the water) of at least one cellulose ether.
A magnetorheological fluid according to claim 19 wherein the rust inhibitor is selected from the group consisting of sodium nitrite and sodium nitrate.
A magnetorheological fluid according to claim 20 further comprising a glycol compound.
A magnetorheological fluid comprising magnetic particles;
- at least one water-soluble suspending agent selected from the group consisting of cellulose ether and biosynthetic gum;
- water;
- and a glycol compound.
