Sichuan anti cracking sticker manufacturer

Description :

　　Anti cracking adhesive tape is a roll type anti cracking waterproof membrane, which is made of a 2mm thick polymer waterproof film coated on a 0.3mm thick * * anti heavy load polypropylene material, and is pressed and compounded together through strict processes, with self-adhesive interlayer anti cracking and waterproof properties. It was an optimized combination and upgraded product of interlayer crack resistance and waterproof materials for highways at that time.

　　Crack resistant stickers are primarily used for the construction and maintenance of the bottom layer of highways, general roads, and urban roads. It has high tensile strength, good resistance and surface viscosity, suitable for the bottom layer of road surface, and can prevent cracks caused by temperature effects and straight loads from reflecting to the surface layer.

　　Usage:

　　1、 Appearance treatment

　　1. It is necessary to remove dust, water, and other debris adhering to the surface, and maintain a dry and clean road surface.

　　2. It is necessary to clean the cracks (joints) with a width between 5-19mm and fill them with sealant.

　　3. It is necessary to clean the cracks (joints) and sunken areas with a width between 19-50mm, fill them with adhesive sand, sealant or asphalt mixture, and compact them to the existing height.

　　4. Cracks or potholes with a width exceeding 50mm need to be cleaned first, then filled with adhesive sand or hot asphalt mixture and compacted to the existing height.

　　5. It is necessary to level the cracks (joints) and sunken areas with different heights.

　　6. It is necessary to tidy or level the protrusions on the bridge deck and road surface until they are flat.

　　2、 Environmental conditions

　　1. It should be used under conditions where the surface temperature is equal to or greater than 21 ℃.

　　2. If the surface temperature is below 10 ℃, it is recommended to use a warm fire to bake the crack resistant adhesive tape, which should be flat, wrinkle free, and not have curled edges.

　　3. If stacking occurs during the laying process, the stacking length is 50mm. It cannot exceed two layers of stacking.

　　4. It is recommended to roll at least three times with a rubber roller after laying the polymer anti cracking adhesive.

　　5. After the laying is completed, vehicles can pass through. However, the interval between laying and the upper layer should not exceed 24 hours.

　　3、 Asphalt overlay

　　1. After the correct installation of anti cracking stickers, they should be closely integrated with the construction of the upper layer to avoid moisture and rain.

　　2. After laying the anti cracking sticker, emulsified asphalt and other adhesive oils can be spread according to the construction specifications of hot asphalt mixture. To prevent vehicles or pavers from sticking to the anti cracking sticker, some fine-grained crushed stones or mixture can be sprinkled on top of the anti cracking sticker.

　　3. The thickness of hot asphalt mixture laid on the anti cracking patch should be greater than 40mm.

　　What should be paid attention to during the construction process of anti crack stickers?

　　The emergence of anti cracking stickers is of great help to highway maintenance. Currently, the anti cracking sticker structure is a comprehensive combination of existing anti cracking and waterproofing technologies. In recent years, it has been successfully applied in highway maintenance work. It is well known that anti cracking adhesive is self-adhesive, easy and fast to apply, and has anti cracking and waterproof effects. But what many people don't know is that if the anti crack sticker construction is not in place, its overall performance cannot be fully utilized. Pay attention to the following points during the construction of anti cracking stickers:

　　1. Remove dust, water, and other debris from the adhered surface, and keep the road surface dry, clean, and smooth.

　　2. The construction temperature of anti crack stickers cannot be lower than 10 ℃, and they can be used directly when the surface temperature is equal to or greater than 21 ℃; If the surface temperature is below 21 ℃, use a warm fire to bake the adhesive surface of the crack resistant sticker. Be careful not to over bake, and the adhesive surface can be melted.

　　3. For cracks (joints), they need to be cleaned and filled with heated sealant; Cracks or pits exceeding 25mm should be cleaned first, and then filled with asphalt sand or hot asphalt mixture and compacted to the existing height.
