MATERIAL FOR GLAND PACKING AND THE GLAND PACKING |
摘要 |
A band-like base member (4) is formed by providing a reinforcement member (20) constructed from a fiber material (2) on at least one side of band-like expanded graphite (3). The base member (4) is twisted to form a cord-like body (40). The outside of the cord-like body (40) is covered by part of the reinforcement member (20), and the remaining part of the reinforcement member (20) is enwound inside the cord-like body (40). A large number of openings (20A) are formed in the reinforcement member (20), and the band-like expanded graphite (3) is faced to the openings (20A). Joining force between the band-like expanded graphite (3) and the reinforcement member (20) is strengthened by joining the band-like expanded graphite (3) to the openings (20A). Shape-keeping ability of the band-like expanded graphite (3) is improved so that sealing ability of a gland-packing material (1) is enhanced. Productivity is increased so that the gland-packing material can be supplied at low cost. Further, the gland-packing material (1) can be reinforced by providing carbon fibers or brittle fibers on the outer side of the cord- like body (40).
