Abstract
PURPOSE:To obtain a low-resistance earthing preventive of corrosion in earths or the like and with working performance being upgraded, by absorbing water and a material formed by mixing substances having freezing-point lowering functions with each other into a high water-absorptive polymer and next burying this polymer around an earth rod. CONSTITUTION:A material formed by mixing one or plural species selected from substances having freezing-point lowering functions (a group of sodium chloride, potassium chloride, ammonium chloride, calcium chloride, glucose, cane sugar, and soluble starch), is mixed together with water into a high water- absorptive polymer, and this polymer is buried around an earth rod. when the substances having the freezing-point lowering functions are thus absorbed into the high water-absorptive polymer, a gel is prevented from freezing or a freezing temperature is much decreased so that the gel is prevented from becoming of high resistance.
