PURPOSE:To prevent durably an effective fixing at a time for bringing the sealing material into contact with the opposite material by incorporating cellulose ether, wax and graphite into the title fixing preventive. CONSTITUTION:Cellulose ether, wax and graphite are incorporated into the title fixing preventive. Further ethyl cellulose is preferably utilized as cellulose ether. Natural wax, petroleum wax and polyethylene wax, etc., are utilized as wax and polyethylene-based wax is preferably utilized. Further both artificial graphite and natural graphite can be utilized as graphite. Thereby fixing between sealing material such as a packing and an O-ring and the opposite material brought into contact therewith is durably prevented. Sealing performance is secured and also replacement of a sealer at a time of maintenance is made easy. |
