1. Material composition and performance characteristics
The YN self-adhesive anti-crack patch uses high-strength reinforced fiber material with bending resistance and high tensile strength. Its core material is specially proportioned to form a high-performance viscoelastic layer. This layer can effectively disperse the concentrated stress when cracks occur, thereby reducing the probability of cracks in cement concrete. Specifically, the tensile strength of the YN self-adhesive anti-crack patch reaches ≥ 600N (≤ 50mm), and its expansibility reaches ≥ 30%.
2. Stress dispersion and crack prevention and control
When cracks appear on the surface of cement concrete, traditional repair methods are often limited to the crack surface and cannot effectively deal with the internal stress concentration problem. The YN self-adhesive anti-crack patch can disperse stress when the crack is deformed through its high tensile strength and elasticity, thereby reducing the risk of crack expansion. The reinforcement layer of the patch can withstand the up and down deformation of the concrete slab, and evenly distribute the stress through its high-strength material, avoiding further cracks caused by concentrated stress.
3. Waterproof performance and durability
Cracks in cement concrete often lead to surface moisture penetration, which can cause further corrosion and damage. YN self-adhesive anti-crack patches have waterproof and puncture-proof properties. Its self-adhesive closure ensures that the patch can be firmly attached to the concrete surface, forming an effective waterproof barrier to prevent moisture penetration. This waterproof ability not only protects the concrete surface from moisture erosion, but also effectively improves the long-term stability and durability of concrete.
4. Low-temperature flexibility and shear resistance
Under low-temperature conditions, the deformation capacity of cement concrete may be limited, thereby increasing the risk of cracks. The low-temperature flexibility of YN self-adhesive anti-crack patches ensures that it can still maintain good elasticity and adaptability under cold conditions. This flexible property enables the patch to function stably on the concrete surface and effectively prevent the formation of cracks even in environments with large temperature fluctuations. In addition, the patch's shear resistance can maintain its structural integrity and effectively prevent the expansion of cracks when facing the lateral impact of road vehicles.
