送速度を遅くする必要があり、生産性が悪かった。Conventionally, the separator for alkaline batteries has been an ion-permeable separator made by graft polymerizing cellophane or polyethylene and irradiated with radiation, and a woven or non-woven fabric made of chemical fibers or natural fibers used as an electrolyte retaining material to reinforce this membrane. →I used it. However, separators made by graft polymerizing cellophane or polyethylene and irradiated with radiation to make them ion-permeable tend to warp when punched and inserted into the anode mixture surface filled with electrolyte, causing them to shift or bend during battery assembly. Problems such as bending and internal short circuits occurred. As a countermeasure, an isolation membrane made by graft polymerizing cellophane or polyethylene and made ion-permeable by irradiation, and a woven or non-woven fabric of chemical or natural fibers are bonded together using an adhesive made by adding methylcellulose, carboxymethylcellulose, etc. to water. (Tokuko Sho 5)

ある。However, the separator manufactured by this method can be used for alkaline mankan batteries, but in silver oxide batteries and mercury oxide batteries, silver ions are deposited in the separator and become metallic silver, or metallic mercury separators are used. After the ion-permeable separator and the electrolyte holding material are bonded together by applying pressure with a roller, an adhesive made of a volatile organic solvent to which a synthetic glue is added is used to hold the electrolyte. After wetting the ion-permeable separator membrane with the adhesive applied to the material side and absorbed by the electrolysis solution holding material, scrape off the excess adhesive on the electrolysis solution holding material surface and then use a roller to remove the excess adhesive. By pressurizing and drying the ion-permeable separator and the electrolyte retaining material, the drawbacks of the prior art can be overcome.

The door is an ion-permeable diaphragm made of cellophane membrane with a thickness of 0.07 yrnn, and 2 is a width 1 which is also wound into a roll.
This is an electrolyte holding material made of rayon nonwoven fabric with a thickness of 0.251711 mm. The ion-permeable separator 1 and the electrolyte holding material 2 were bonded together by applying pressure with a bonding roller 3, and then attached to an adhesive container 4 containing an adhesive made of a volatile organic solvent to which a synthetic adhesive was added. The nozzle 5 applies and absorbs the adhesive 1 on the electrolyte holding material side of the bonded ion permeable separator and electrolyte holding material, wets the ion permeable separator as well, and then scrapes off the excess adhesive using the scraping plate 6. After removing the agent and applying pressure with a pressure roller 7, the material is passed through a drying oven 8 and dried, thereby producing a bonded separator 9 by winding it.

タを製造することができる。As described above, after the ion-permeable separator and the electrolyte holding material are bonded together by applying pressure with a roller, an adhesive made of a volatile organic solvent to which a synthetic glue is added is applied to the side of the electrodeposited solution reservoir. After absorbing the adhesive into the electrolyte holding material and wetting the ion-permeable separator with the adhesive, scrape off the excess adhesive on the surface of the electrolyte holding material and remove the excess volatile solvent from the separator. Because it wants to be absorbed, the drying time is significantly shortened, making it possible to manufacture laminated separators with high work efficiency.
