本発明は、比較的少量の樹脂て甫懺14藩1を結着する
セパレータの製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a separator that binds together 14 layers of resin using a relatively small amount of resin.

のであった。Conventionally, the method for binding separator materials such as carphone or inorganic compounds with resin powder such as polytetrafluoroethylene is to knead it with a column lubricant such as water or an organic compound solvent, and then knead it with a pair of calender rolls. extrusion,
After closing the notebook, the notebook was folded and extruded again at right angles to the previous extrusion direction, but the distance between the rolls was changed to obtain a durable sheet with a final thickness.
しかしこの方法に下記の欠截かある。However, this method has the following deficiencies.
(1)通常、セパレータ性能を向上させるために、結着
剤としての蹟]指附を極力少量とするので、かなり作り
つらく熟練を要する。(1) Normally, in order to improve separator performance, the amount of binder used as a binder is kept as small as possible, so it is quite difficult to make and requires skill.
(2)手工業的方法であるため、性質の安定性(こ欠け
、又、巾か一定でない。(2) Because it is a manual method, the properties are not stable (chips and widths are not constant).
(3)製造工数かかなりかかり、コスト高となる。(3) It takes a considerable amount of manufacturing man-hours, resulting in high costs.

Figure 1 shows Polytetrafluor [Coechile/Resin 10L1]
96 is a schematic diagram of an apparatus for making a normal Teflon 7 raw tape. That is, polybutrough "eye" ethylene fat
Mix the fat paste and petroleum-based lubricant in a fletter, and put the Sentai Eki-shaped object 2 formed in the preform mold into the extruder filter.
A thin notebook-like raw tape was obtained through an extrusion calender roll 5 and a 11" roll 6 at a bistono 4 with the aid of a feeding speed.

In comparison, from the extrusion 1]8 with a small surface edge, it is extruded as a flexible round bar 9 shaped like a noodle, and finally a sheet 10 is formed.
It is possible to do this. However, since the resin arsenic used to bind the separator grains is 50941 or less even when filled with liquid, the structure of the extruder 5 described above cannot extrude without clogging before extrusion [-18]. It ran out and I couldn't get round bar 9 anymore.

However, the extruded mixture will be sent out, so it will be a target. My friend told me that even in the case of a combination drug, I would probably get a C on sheet 15.However, when I actually tried this, I got no. Perhaps because of this, the above-mentioned Kichidojin 1st Calendar had the disadvantage that a hard lump formed in the front of the 13th wheel, causing a blockage and making it impossible to send out the calendar.

こつながる。Practical drawing 111: In the schematic diagram of the separator manufacturing apparatus as shown in Fig.
2.25 is the force l/tutah lnifur, 24 is the polybut trough 1-1 rJ ethylene, and the contact roll part with the shape shown in the diagrams c and d is shown, and 25 is the polybute trough []0 ethylene/resin m powder and alcohol-based moisturizer. 1 is a j-well mixture with aggregate, 26 is a hydraulic piston, and 27 and 28 are molded sheet-like separators. Regarding the manufacturing method, the kneaded a25 sufficiently kneaded with a pressurized kneader or the like is filled into the /su/tar 21, extruded with a hydraulic piston 26 to the calender ""-ru 22, and the sheet 27 is placed on the calender roll. 26 and get No. 1-28. / - The gutter 27 is provided in the gap between the linter 21 and the calender roll 22.
A contact roll portion 24 having the shape shown in is attached to the printer 21.
Therefore, the extrusion is limited to a certain cl]. In the method described in ``2'', the bis 1-2 is used to prevent clogging that occurs when the mixed wire 25 containing polytetrafluoroethylene is extruded from a narrow place as in the conventional device.
Since the mixed material 25 extruded in step 6 is pressed against the calendar roll 22 or turned into notes by rotating the calendar roll 22, the pressure of the screw 1-726 is sufficient to prevent clogging. That's C1-27.
28 can be obtained continuously without forming any breaks or holes. In addition, the force of force of =5-bis l-726 is 2 to 20 when using one of the above 1# kneaded materials.It can be done with a pressure of K17/C+7.2) If it is under 1g/C119, it is Due to lack of notebook pressure (I can't convert this continuous sea to 1~, and 2D
Kg/cJ or more -))/The feed of the tar roll may catch up, or the pressurizing force may be too thick and cause the breakdown of the tar roll (

As shown in the table above, the separator prepared by method B not only has a low electrical resistance value, but also is more stable than method A. Contains less. This is stable when produced in electric/b'II vinegar, and in method Δ IJ-
Depending on the type of kneading, it is difficult to knead the material (Jj, N is 1/-1~), and this occurs because the density becomes higher than necessary and the porosity becomes smaller.
