<p>PROBLEM TO BE SOLVED: To realize easy transport, free use of an existing space and easy installation by constituting drawing cloth by covering organic fiber-made woven fabric with rubber and plastic by working a film material laminated by one layer or more into a bag shape. SOLUTION: Permeation of an electrolyte is restrained and long-term insulating performance and durability are improved by using drawing cloth by covering organic fiber-made woven fabric, such as electrolyte resistant polyethylene with thermoplastic elastomer such as chemical resistant butyl rubber or plastic of vinyl chloride or polyolefine. Because its being a bag-shaped flexible vessel, it can be bent by forming a habit into a housing space shape, an electrolyte is filled so as to be brought into close contact with the whole, and an excess reinforcing member becomes unnecessary by an internal pressure load besides effectively using a space. Strength is imparted by using polyester, and the drawing cloth may be superior as a self-standing tank in a wide space. It is preferable that the outside of the bag-shaped vessel be covered with a metal or a rubber and plastic film, having a prescribed gas permeability coefficient, and liquid leakage and air permeability can be improved.</p> |
