Abstract
(EN)
A conveyor belt 10 is formed by covering a belt core 14 with cover rubber 12. The cover rubber 12 is configured such that at least a portion of the surface thereof has a micro-asperity structure, and as a result of the micro-asperity structure, the surface roughness is 1 µm to 12 µm, the sharpness is 2 to 9, and the specular gloss with an incident angle of 60° is 0.1 to 10. In particular, it is preferable that the surface roughness be 2 µm to 5 µm, that the sharpness be 3 to 5, and that the specular gloss with an incident angle of 60° be 0.1 to 3. Due to this configuration, the conveyor belt 10 is less likely to have external appearance defects resulting from bloom.

La présente invention concerne une bande transporteuse (10) qui est formée par le revêtement d'une partie centrale de bande (14) au moyen d'un caoutchouc de revêtement 12. Le caoutchouc de revêtement (12) est configuré de sorte qu'au moins une partie de sa surface présente une structure de micro-aspérité, et en conséquence de la structure de micro-aspérité, la rugosité de surface est de 1 µm à 12 µm, la netteté est de 2 à 9 et le brillant spéculaire avec un angle incident de 60° est de 0,1 à 10. En particulier, il est préférable que la rugosité de surface soit de 2 µm à 5 µm, que la netteté soit de 3 à 5 et que le brillant spéculaire avec un angle incident de 60° soit de 0,1 à 3. Grâce à cette configuration, la bande transporteuse (10) est moins susceptible de présenter des défauts d'aspect externe résultant de l'efflorescence.

コンベヤベルト10は、ベルト芯体14をカバーゴム12で被覆して形成されている。カバーゴム12は、表面の少なくとも一部に微細凹凸構造が形成されており、当該微細凹凸構造によって、表面粗さが1μm以上12μm以下、かつ尖り度が2以上9以下、かつ入射角60°における鏡面光沢度が0.1以上10以下に形成されている。特に、表面粗さが2μm以上5μm以下、かつ尖り度が3以上5以下、かつ入射角60°における鏡面光沢度が0.1以上3以下に形成するのが好ましい。これにより、コンベヤベルト10においてブルームに起因する外観不良が生じにくくなる。
