６の平均値である。EXAMPLES Hereinafter, examples of the present invention will be explained with reference to the drawings. FIG. 2 is a half-sectional view of a cylindrical mercury battery (height 1e, Byig, outer diameter 16.4H) using separators obtained conventionally and according to the present invention. A general method for manufacturing this battery is to insert a positive electrode mixture 1 into a positive electrode case 2 together with a positive electrode ring 3 and to mold the positive electrode mixture under pressure. A cylindrical separator 4 with a bottom is inserted into the hollow part of the molded positive electrode mixture 1, and a gelled zinc negative electrode 5 containing a mixture of frozen zinc powder, a gelling agent, and an alkaline electrolyte is placed inside the separator 4. After filling a predetermined amount of the battery, a negative electrode terminal cap consisting of a sealing plate 7 to which a current collector 6 is welded and an insulating gasket 8 is loaded, and the opening edge of the positive electrode case 2 is sealed to form a battery. The Kochi separator is characterized by the present invention, and as shown in FIG.
A thin cloth having a film 4a of kaolinite particles adsorbing polyvinyl alcohol obtained by impregnating it with an aqueous solution consisting of 0% by weight and 0.001% by weight of polyvinyl alcohol and drying it at 45°C for 12 hours. Consisting of Cylindrical mercury batteries of Examples were assembled using the above-described separator according to the present invention and a conventional separator. At that time, about 5 caps of brass powder were mixed into the gap between the outer surface of the separator and the inner surface of the positive electrode mixture, and 100 separators were assembled. After the battery was completed, we tested the open circuit voltage and continuous discharge duration until the terminal voltage reached 0.9V with a load resistance of 62Ω at a temperature of 46°C according to the schedule shown in the table below. was gotten. The open circuit voltage data is the average value of 100 tests, and the duration data is the average value of 6 tests.
次に本発明における各々の特徴について述べる。Next, each feature of the present invention will be described.

昇する。Next, regarding the concentration of the aqueous solution, adsorption, charging properties, and water-resistant adhesive strength vary depending on the degree of polymerization and saponification of polyvinyl alcohol, and the type and particle size of clay or soft soil. However, the common thing that can be said is that the higher the concentration, the stronger the separator surface becomes against foreign body reactions, but the short-circuit current of the battery decreases, and conversely, the lower the concentration, the opposite tendency for these characteristics. . In addition, the mixing weight ratio of polyvinyl alcohol and clay or soft soil is also determined by the property level and type of the two.
Various combinations of particle sizes can affect the relative turbidity and cohesiveness of aqueous solutions.
Water resistant adhesion strength is different. However, the common thing that can be said is that the higher the weight ratio of polyvinyl alcohol, the stronger the water-resistant adhesion and the reinforcement of the surface of the separator, but the aggregation effect of polyvinyl alcohol in the battery weakens9 and the relative turbidity increases. .
逆にポリビニルアルコールの重量比率が低いほど、これ
らの特性は逆の傾向となる。Conversely, as the weight ratio of polyvinyl alcohol decreases, these properties tend to be opposite.
