Guangdong road crack sticker price Guangzhou double-sided adhesive tape wholesale

Description :

　　The main features of our company's anti cracking stickers are:

　　1. Excellent crack prevention effect. The crack prevention adhesive has high tensile strength and a product elongation rate of ≥ 30%. When two cement concrete slabs are horizontally displaced by 1mm (with a base joint width of 4mm), anti cracking stickers can effectively alleviate and disperse the stress. After opening and closing 10000 times, there was no "crack prevention sticker".

　　2. It has excellent low-temperature flexibility and good resistance to up and down shear. Due to the "crack resistant adhesive" substrate and elasticity, the material does not break when bent 180 ° along a ф 20mm glass rod at a low temperature of -20 ℃. When the "crack prevention sticker" pasted on two cement concrete slabs is displaced up and down by 0.5mm (with a base joint width of 4mm), after repeated up and down displacement of 10000 times, due to the good flexibility and elongation of the "crack prevention sticker", there is no "crack prevention sticker" (the allowable vertical displacement value in conventional design is generally not greater than 0.06mm).

　　3. Good adhesion performance: "Anti cracking stickers" have good adhesion with both cement concrete base and asphalt concrete surface, with an adhesion strength greater than 4N/mm. After being rolled by hot asphalt concrete, the adhesion performance is greatly improved, so it is not easy to slip when subjected to horizontal force. Under high temperature conditions of 50 ℃, the shear strength of the "anti cracking sticker" can reach above 0.15Map.

　　4. After being impacted at a height of mm with good perforation resistance, the "crack prevention sticker" does not leak water after being subjected to a constant pressure of 0.3MPa for 0.5h.

　　5. Good waterproof sealing due to the self-adhesive covering layer on the lower surface of the "crack prevention sticker" being greater than 1mm. After being pressed by hot asphalt concrete, it is completely combined with cement concrete, greatly improving the waterproof sealing and preventing surface water from seeping into the cracks of the cement concrete slab, thus ensuring the stability of the foundation. Especially when subjected to the horizontal thrust of the driving vehicle, its covering layer has good self adhesiveness and properties, ensuring waterproof sealing.

　　6. The construction of "crack prevention stickers" is convenient, and the construction is self-adhesive cold construction. As long as the isolation paper (film) is removed, it can be directly pasted on the treated cement concrete base. Convenient construction and fast speed. At the same time, it is an environmentally friendly product that does not produce pollution.
