Introduction to anti crack sticker
Self adhesive anti crack sticker ( abbreviation YN Anti crack sticker ) The reinforced fiber materials with good folding performance, tensile strength and corrosion resistance are selected as the base material, and the viscoelastic materials with different processing ratios are covered up and down.
When cement When the concrete cracks and deforms, because the tensile strength of the base material of the "anti crack sticker" is greater than the bonding strength, the originally concentrated stress is dispersed through the cover layer of the anti crack sticker, avoiding and reducing asphalt The possibility of concrete cracking. When the adjacent cement concrete plate is repeatedly cut up and down within a certain range, the reinforcing fiber used has the folding and extensibility of human * * *. Therefore, it is not easy to break the "anti crack sticker". Adhering to the "anti crack sticker" has a good self-adhesive blocking property, which blocks the surface water cement concrete plate expansion joint ( Crack ) Internal, ensure foundation stability .
usage method
one , clear adhere Dust, water and other sundries on the surface shall keep the road dry and clean.
two , width in 5—19mm Clean the crack (joint) between them and fill them with sealant.
three , width in 19—50mm Clean the crack (joint) and subsidence area between them, and use glue sand, sealant or Asphalt mixture Fill and compact to the existing degree.
four , width exceeds 50mm The cracks or pits shall be cleaned first, then filled with mortar or hot asphalt mixture and compacted to the existing degree.
five Leveling treatment shall be carried out for cracks (joints) and sagging areas with different degrees.
six . The protrusions of bridge deck and pavement shall be cleaned or leveled until they are flat.
