Definitions
- the present invention relates to a ground packing expanded graphite knitting yarn used for a shaft sealing portion of a fluid device or the like.
- the present invention relates to an expanded graphite knitting yarn capable of improving the pressure resistance of ground packing.
- a knitting yarn 3 shown in FIG. 13 has been known as a ground packing knitting yarn used for, for example, a shaft sealing portion of a fluid device.
- the knitting yarn 3 has a plurality of reinforcing fibers 2 embedded in the longitudinal direction thereof at intervals in the width direction of the expanded graphite tape 1 having a predetermined width.
- the expanded graphite tape 1 has a weak tensile strength and is brittle, and the edges of the la and lb at both ends in the width direction have a small exfoliation resistance between the expanded graphite particles. No. That is, the expanded graphite particles are easily peeled off at the edges of both ends 2a and 2b in the width direction.
- both ends la and lb in the width direction are formed. Since large tensile and shearing forces are applied to the edges, cracks are generated from the edges of la and lb at both ends in the width direction. Therefore, the expanded graphite particles at and near the edges of both ends 1a and 1b in the width direction are exfoliated.
- An object of the present invention is to provide an expanded graphite knitting yarn capable of reducing or preventing exfoliated graphite particles from falling off.
- the expanded graphite knitting yarn according to the present invention has an expanded graphite tape in which reinforcing fibers are embedded in an expanded graphite knitting yarn used for ground packing. It is characterized in that at least one end in the width direction of the knitting yarn base material is twisted so as to be directed inward in the width direction of the knitting yarn base material. According to the present invention, since at least one end in the width direction of the knitting yarn base is twisted so as to face inward in the width direction of the knitting yarn base, the twisting is performed.

At least one end in the width direction of the knitting yarn base material in which the strong fiber is embedded is bent so that one end of the knitting yarn base material is directed inward in the width direction of the knitting yarn base material and between the two end portions in the width direction. It is characterized by being twisted. According to the present invention, at the time of twisting, a large tensile force or shearing force does not directly act on the edge of the one end, and a crack is generated and the crack is generated from the edge of the one end.
- the width between both ends in the width direction of the knitting yarn base material is bent, so that the width direction of the knitting yarn base material The dimensions are reduced, the twisting becomes easier, and the twisting workability can be improved.
- Still another expanded graphite knitting yarn according to the present invention is an expanded graphite knitting yarn used for ground packing, in which reinforcing fibers are embedded in an expanded graphite tape and blast processing is performed.
- the yarn base material from which a part of the expanded graphite particles on the surface side of the expanded graphite tape has been removed is twisted.
- a part of high-density and highly-oriented expanded graphite particles, which are easily cracked, on the surface side of the expanded graphite tape is removed by blasting. Therefore, even when a large tensile force is applied to both ends in the width direction of the knitting yarn base material during the twisting process, the cracks are generated and the cracks are generated due to the cracks. It is possible to reduce the exfoliation of exfoliated graphite particles.

It is characterized by being twisted so as to bend between the two ends in the width direction.
- a large tensile or shearing force does not directly act on the edge of the one end, and cracks and cracks are generated from the edge of the one end. It is possible to reduce the exfoliation of the expanded graphite particles that accompanies it. Since the portion between both ends is bent, the widthwise dimension of the knitting yarn base material is reduced, twisting is facilitated, and twisting workability can be improved.
- Still another expanded graphite knitting yarn according to the present invention is an expanded graphite knitting yarn used for ground packing, in which reinforcing fibers are embedded in an expanded graphite tape and used for blasting.
