The cushioning material for supporting a tube body according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view schematically showing an example of a cushioning material for supporting a tube body of the present invention.

図1に示すように、管体支持用緩衝材10は、特に形状は限定されないが、平面視矩形が好ましい。なお、緩衝材は複数に分割配置されて使用しても良く、重ねて使用しても良い。また、管体に緩衝材を連続で複数回以上巻き付けて使用しても良い。 As shown in FIG. 1, the shape of the cushioning material 10 for supporting the tube body is not particularly limited, but a rectangular shape in a plan view is preferable. The cushioning materials may be divided into a plurality of materials and used, or may be used in layers. Further, the cushioning material may be continuously wound around the tube body a plurality of times or more.

管体支持用緩衝材10は、管体と管体を支持する管体支持具との間に配置されることになり、管体には、高温流体が流れることになる。
なお、高温流体の温度は400〜800℃であることが望ましい。
The tube body support cushioning material 10 will be arranged between the tube body and the tube body support tool that supports the tube body, and a high temperature fluid will flow through the tube body.
The temperature of the high temperature fluid is preferably 400 to 800 ° C.

管体支持用緩衝材10を用いると、管体に高温流体が流れ、管体が高温になったとしても、管体支持用緩衝材10は劣化しにくい。
そのため、管体に高温流体が流れたとしても、長期間、緩衝効果を得ることができる。
When the cushioning material 10 for supporting the pipe body is used, even if the high temperature fluid flows through the pipe body and the temperature of the pipe body becomes high, the cushioning material 10 for supporting the pipe body is unlikely to deteriorate.
Therefore, even if a high-temperature fluid flows through the tube, a buffering effect can be obtained for a long period of time.

管体支持用緩衝材10の厚さは、配置される空間に合わせて適宜決定することが望ましいが、
1mm以上であることが望ましく、1〜50mmであることがより望ましい。また複数の緩衝材を重ねて使用しても良い。
管体支持用緩衝材の厚さが1mm未満であると、充分な緩衝効果が得られず、管体が破損しやすくなる。

管体支持用緩衝材10は、無機繊維からなることが望ましい。
無機繊維は耐熱性が高い。そのため、管体支持用緩衝材10が無機繊維からなると、管体支持用緩衝材10は劣化しにくい。
It is desirable that the cushioning material 10 for supporting the tube body is made of an inorganic fiber.
Inorganic fibers have high heat resistance. Therefore, when the tube body support cushioning material 10 is made of inorganic fibers, the tube body support cushioning material 10 is unlikely to deteriorate.

管体支持用緩衝材10が無機繊維からなる場合、無機繊維の平均長は、0.1〜150mmであることが望ましく、10〜80mmであることがより望ましい。
無機繊維の平均繊維長が0.1mm未満であると、無機繊維の繊維長が短すぎるため、無機繊維同士の交絡が不充分となり、管体支持用緩衝材の強度が得られにくくなり、管体支持用緩衝材の形状保持性が低下しやすくなる。
繊維の平均繊維長が150mmを超えると、繊維の繊維長が長すぎるため、管体支持用緩衝材を構成する繊維本数が減少する。そのため緻密性が低下しやすくなる。
When the cushioning material 10 for supporting the tube body is made of inorganic fibers, the average length of the inorganic fibers is preferably 0.1 to 150 mm, more preferably 10 to 80 mm.
If the average fiber length of the inorganic fibers is less than 0.1 mm, the fiber lengths of the inorganic fibers are too short, the entanglement between the inorganic fibers becomes insufficient, and it becomes difficult to obtain the strength of the cushioning material for supporting the pipe body. The shape retention of the body support cushioning material tends to decrease.
If the average fiber length of the fibers exceeds 150 mm, the fiber length of the fibers is too long, and the number of fibers constituting the cushioning material for supporting the tube body decreases. Therefore, the fineness tends to decrease.

無機繊維長の測定は、ピンセットを使用して管体支持用緩衝材から無機繊維が破断しないように抜き取り、光学顕微鏡を使用して繊維長を測定する。
本明細書において、平均繊維長とは、管体支持用緩衝材から無機繊維300本を抜き取り、繊維長を計測した平均長さを意味する。管体支持用緩衝材から無機繊維を破断せずに抜き取れない場合、管体支持用緩衝材を脱脂処理して、脱脂済み管体支持用緩衝材を水の中へ投入し、無機繊維同士の絡みをほぐしながら無機繊維が破断しないように採取すると良い。
In the measurement of the inorganic fiber length, the inorganic fiber is extracted from the cushioning material for supporting the tube body without breaking using a tweezers, and the fiber length is measured using an optical microscope.
In the present specification, the average fiber length means the average length obtained by extracting 300 inorganic fibers from the cushioning material for supporting the tube and measuring the fiber length. If the inorganic fibers cannot be removed from the cushioning material for supporting the pipe without breaking, the cushioning for supporting the pipe is degreased, and the degreased cushioning for supporting the pipe is put into water, and the inorganic fibers are put together. It is advisable to collect the fibers so that the inorganic fibers do not break while loosening the entanglement.

無機繊維の平均繊維径は、1〜20μmであることが望ましく、2〜15μmであることがより望ましく、3〜10μmであることがさらに望ましい。
無機繊維の平均繊維径が1μm未満であると、強度が弱く、衝撃等により無機繊維が裁断されやすくなる。
無機繊維の平均繊維径が20μmを超えると、繊維径が太すぎ無機繊維自体のヤング率が高くなり管体支持用緩衝材の柔軟性が低くなりやすくなる。
The average fiber diameter of the inorganic fibers is preferably 1 to 20 μm, more preferably 2 to 15 μm, and even more preferably 3 to 10 μm.
When the average fiber diameter of the inorganic fibers is less than 1 μm, the strength is weak and the inorganic fibers are easily cut by impact or the like.
When the average fiber diameter of the inorganic fiber exceeds 20 μm, the fiber diameter is too large and the Young's modulus of the inorganic fiber itself becomes high, and the flexibility of the cushioning material for supporting the tube tends to be low.

無機繊維としては、アルミナ繊維、アルミナ−シリカ繊維、シリカ繊維、グラスウール、ロックウール等が挙げられる。これらの中では、アルミナ−シリカ繊維であることが望ましい。
これらの無機繊維は耐熱性が高く、このような無機繊維により形成されたマット材は、温度変化によって形状変化しにくい。
Examples of the inorganic fiber include alumina fiber, alumina-silica fiber, silica fiber, glass wool, rock wool and the like. Of these, alumina-silica fibers are desirable.
These inorganic fibers have high heat resistance, and the mat material formed of such inorganic fibers does not easily change its shape due to temperature changes.

さらに、無機繊維がアルミナ−シリカ繊維である場合、アルミナとシリカの組成比は、重量比でアルミナ(Al):シリカ(SiO)=60:40〜98:2であることが望ましく、アルミナ(Al):シリカ(SiO)=70:30〜75:25であることがより望ましい。
無機繊維の結晶化率は0.1〜80.0%であることが望ましく、0.5〜10.0%がより望ましい。

The crystallization rate of the inorganic fiber is preferably 0.1 to 80.0%, more preferably 0.5 to 10.0%.

管体支持用緩衝材10では、無機繊維が2種以上併用されていてもよい。 In the tube body support cushioning material 10, two or more kinds of inorganic fibers may be used in combination.

管体20と管体支持具30との間に配置される前の管体支持用緩衝材10の嵩密度は特に限定されないが0.05〜0.25g/cmであることが望ましい。
嵩密度が0.05g/cm未満であると、アルミナ繊維の絡み合いが弱く、マットの引張強度が小さい。また、アルミナ繊維が剥離しやすいため、管体支持用緩衝材の形状を所定の形状に保ちにくくなる。
嵩密度が0.25g/cmを超えると、管体支持用緩衝材が硬くなり、管体への巻き付け性が低下し、管体支持用緩衝材を管体の表面に沿う様に曲げた際、表面が割れやすくなる。
The bulk density of the cushioning material 10 for supporting the tube before being arranged between the tube 20 and the tube support 30 is not particularly limited, but is preferably 0.05 to 0.25 g / cm 3 .
When the bulk density is less than 0.05 g / cm 3 , the entanglement of the alumina fibers is weak and the tensile strength of the mat is small. Further, since the alumina fibers are easily peeled off, it becomes difficult to keep the shape of the cushioning material for supporting the pipe body in a predetermined shape.
When the bulk density exceeds 0.25 g / cm 3 , the cushioning material for supporting the tubular body becomes hard, the wrapping property around the tubular body is lowered, and the cushioning material for supporting the tubular body is bent along the surface of the tubular body. At that time, the surface becomes fragile.

管体支持用緩衝材10が無機繊維からなる場合、管体支持用緩衝材10は、有機バインダを含むことが望ましい。
有機バインダは、無機繊維同士を接着し、管体支持用緩衝材から無機繊維が飛散することを防ぐことができる。

これらの有機バインダは、2種以上併用してもよい。
When the cushioning material 10 for supporting the pipe body is made of an inorganic fiber, it is desirable that the cushioning material 10 for supporting the pipe body contains an organic binder.
The organic binder can bond the inorganic fibers to each other and prevent the inorganic fibers from scattering from the cushioning material for supporting the tube body.
Examples of the organic binder include water-soluble or water-dispersed organic polymers such as acrylic resin, acrylate-based latex, rubber-based latex, carboxymethyl cellulose or polyvinyl alcohol, thermoplastic resins such as styrene resin, and thermosetting resins such as epoxy resin. And so on.
Two or more of these organic binders may be used in combination.

管体支持用緩衝材10が有機バインダを含む場合、有機バインダの含有量は、無機繊維の重量に対し、8wt%以下であることが望ましく、0.1〜3.0wt%であることがより望ましい。
本発明の管体支持用緩衝材は、高温流体が流れる管体を固定するために使用されるので、管体が高温になると、管体支持用緩衝材に含まれる有機バインダが熱により分解する。
有機バインダの含有量が8wt%を超えると、有機バインダが分解して発生するガスの量が多くなり、白煙の発生等の問題が生じる。
