Method of manufacturing ink follower for water-base ballpoint pens |
摘要 |
Lot-to-lot or time-dependent instability in quality of the known ink follower for water-base ballpoint pens is overcome. Particulate silica, or organic-treated clay is kneaded as thickener with base oil to prepare gel matter. The gel matter is pressurized to eliminate fine bubbles to yield ink follower for water-base ballpoint pens. The pressurization is preferably performed at 2 atm or higher. The elimination of the bubbles is more effective when the ink follower is, under pressurization, stirred and/or heated. <IMAGE> |
