摘要： A sheet-like reinforcing member (20) configured by a fibrous material (2) is disposed at least on one face of a strip-like expanded graphite (3) to form a strip-like base member (4). The base member (4) is stranded to be formed as a cord-like member (40). At this time, the outer side of the cord-like member (40) is covered by a portion of the reinforcing member (20), and the remaining portion of the reinforcing member (20) is involved in the cord-like member (40). A large number of openings (20A) are formed in the reinforcing member (20), and the strip-like expanded graphite (3) faces the openings (20A). The expanded graphite (3) is engaged with the openings (20A), whereby the coupling force between the strip-like expanded graphite (3) and the reinforcing member (20) is enhanced. The shape-retaining property of the strip-like expanded graphite (3) is improved to enhance the sealing property, and the productivity is improved so that a material can be economically provided. Furthermore, carbon fibers or brittle fibers are placed outside of the cord-like member (40), so that a gland packing material (1) can be reinforced.

摘要： A strip-like expanded graphite (3) is disposed on one face of a sheet-like reinforcing member (20) configured by a fibrous material (2) to form a strip-like base member (4). The base member (4) is stranded to be formed as a cord-like member (40). The outside of the cord-like member (40) is covered by a portion of the strip-like expanded graphite (3), and the whole reinforcing member (20) and the remaining portion of the strip-like expanded graphite (3) are involved in the cord-like member (40). A large number of openings (20A) are formed in the reinforcing member (20). The strip-like expanded graphite (3) faces the openings (20A). The strip-like expanded graphite (3) is engaged with the openings (20A), whereby the coupling force between the strip-like expanded graphite (3) and the reinforcing member (20) is enhanced. The gland packing material (1) is provided by the fibrous material with high tensile strength, and easily subjected to a braiding or twisting process. Furthermore, the gland packing material (1) has a high shape-retaining property, and exerts a high sealing property that is originally possessed by an internal reinforcement structure. Moreover, the used amount of an adhesive agent can be reduced, and reduction of the sealing property due to hardening or burning of the adhesive agent can be avoided.

摘要： The present invention relates to a braiding yarn made of expanded graphite for a gland packing which is to be used in a shaft seal part of a fluid apparatus or the like. In the braiding yarn made of expanded graphite of the invention, an expanded graphite tape of a predetermined width is folded into a valley fold in the longitudinal direction, both end portions in the width direction of the expanded graphite tape are bent so as to be directed toward the inner side of the width direction of the expanded graphite tape, and the outer periphery of the tape is covered by a reinforcing member configured by a braided body of stainless steel wires. The expanded graphite tape may be twisted. Reinforcing fibers may be embedded in the expanded graphite tape. Part of expanded graphite particles on the side of the surface of the expanded graphite tape may be removed away. According to the expanded graphite tape of the invention, flaking of expanded graphite particles during a braiding process is reduced or prevented from occurring, and the pressure resistance of a gland packing can be enhanced.

摘要： An expanded graphite sealing material is provided in which the adaptability of the principal face of an expanded graphite base member is improved, the bonding strength to a coating layer and the like can be increased, and the sealing properties can be enhanced. A method of producing such a sealing material and a gasket sheet using the sealing material are also of concern. On at least a portion of a principal face of the expanded graphite base member in which expanded graphite particles are pressurized and integrated together, opened thin-leaf graphite portions are formed. The principal face of the expanded graphite base member having the thin-leaf graphite portions can be impregnated with a sealing member such as PTFE or covered with a coating layer. As the form of the sealing material, a sheet, a press-molded product, a fabric, a string, or a braided article can be adopted.

摘要： An expanded graphite knitting yarn according to the present invention is covered or bound and covered with a reinforcing material made of a braided body such as stainless steel line members, before an outer periphery of an expanded graphite tape having a predetermined width, which has been subjected to a twisting process, is braided. Therefore, an amount of the expanded graphite particles exfoliated from ends of the expanded graphite tape in the twisting process can be significantly reduced. Moreover, this can prevent the expanded graphite particles from being exfoliated from the end of the expanded graphite tape in a braiding process. Furthermore, the plural expanded graphite knitting yarns are put together and subjected to either braiding or twisting process, thereby forming a gland packing. This can enhance a sealing property and a pressure resistance property of the gland packing.

摘要： The present invention relates to a gland packing which is made of a material configured by laminating an expanded graphite tape into a spiral shape by winding. The gland packing can prevent penetration leakage through minute gaps existing in the laminated parts, from occurring, can be sufficiently deformed so as to exhibit sure sealing properties even at a low tightening force, and has properties which result in a small amount of wear so as to ensure high sealing properties, so that high sealing performance can be maintained for a long term. In the gland packing, circumferentially projected parts are disposed on end faces of a die mold packing part made of an expanded graphite tape laminated into a spiral shape so as to be integrated with the part. Ring-like seal members are brought into tight contact with the end faces of the die mold packing part excluding the circumferentially projected parts in such a manner that the circumferentially projected parts project in an axial direction beyond the outer faces of the respective ring-like seal members.
