  • snow and ice When snow and ice arrive on road signs and bridges, the attached snow and ice gradually grows and increases in weight, and when the weight exceeds the adhesive force, it falls as a mass of snow and ice. Depending on the condition in which snow and ice contain a small amount of water, snow and ice can grow to a considerably large weight due to hydrogen bonding and van der Waals forces derived from the water. When the snow and ice blocks fall off from road signs or bridges and fall, if vehicles or pedestrians pass under them, it may be catastrophic in some cases.

  • the adhesion between the outer surface of the layer and the water droplets exceeds the bonding force between the molecules in the water droplets, making snow and ice more likely to occur.
  • the receding contact angle is less than 50 degrees, snow and ice are more likely to occur for the same reason as for the advancing contact angle, and if the receding contact angle is greater than the advancing contact angle, water droplets will easily fall down and will not easily slide down. Therefore, snow and ice properties are reduced.

  • Constant load non-breaking sliding means that frozen snow and ice slides on the outer surface of the coating layer without causing breakage of the freeze-bonding joint at the interface with the outer surface of the coating layer due to gravity or external force acting on itself. That is, when gravity or external force is applied, rather than suddenly breaking the freezing joint at a certain point and falling off the outer surface of the coating layer, the gravity or external force is applied from the point of time when the gravity or external force is applied at a certain point.

Abstract

Lorsque la neige et la glace s'accumulent sur la surface extérieure d'une structure d'extérieur, on peut développer l'effet de prévention d'accumulation de neige et de glace en faisant glisser rapidement la neige et la glace tenant à la surface extérieure de la structure extérieure grâce à la propriété de glissement de neige et de glace de la surface extérieure d'une couche de couverture. Pour cette raison, sans nécessiter une hydrophobicité du niveau de la super-hydrophobicité pour prévenir l'accumulation de neige et de glace, la neige et la glace collante peuvent glisser rapidement du fait d'une couche de couverture formée par un procédé relativement bon marché et simple, de façon que la durée pendant laquelle la neige et la glace restent collantes est ramenée à un minimum de façon qu'avant que la neige et la glace collantes ne se transforment en paquets de neige ou en corniches, il soit possible de les faire glisser et en même temps de supprimer l'aspect collant de la neige et de la glace.
