Introduction to anti crack sticker
Self adhesive anti crack sticker ( abbreviation YN Anti crack sticker ) , is the tensile strength good Reinforcing fiber material that can prevent corrosion is the base material , the viscoelastic material with matching processing performance is covered up and down.
When cement When the concrete cracks and deforms “ Anti crack sticker ” The tensile strength of the base material is greater than the bonding strength, so that the originally concentrated stress is dispersed through the cover layer of the anti crack sticker, reducing the 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 resistance and extensibility of human * * *. Therefore, it is not easy to use “ Anti crack sticker ” Break, insist “ Anti crack sticker ” It has good self-adhesive property, which blocks the surface cement concrete plate expansion joint ( Crack ) Internal, ensure foundation stability .
Main products***
one Crack prevention effect of * * * 2mm Thick “ Anti crack sticker ” , its tensile strength ≥600N/50mm , product extension ≥ Thirty percent. When two cement concrete slabs are horizontally displaced 1mm( Base seam width 4mm) The anti crack sticker can play a good role in dispersing. Meridian opening and closing ten thousand Times, “ Anti crack sticker ” No damage.
two It has * * * low temperature flexibility and good resistance to up and down shear “ Anti crack sticker ” The base material is soft and elastic -20℃ At low temperature, along ф20mm Of Glass Great. curved one thousand and eight hundred The material does not break. When pasted on two cement concrete slabs “ Anti crack sticker ” Up and down displacement 0.5mm( Base seam width 4mm) , after repeated up and down displacement ten thousand Times due to “ Anti crack sticker ” Good flexibility and elongation ,“ Anti crack sticker ” No damage ( The allowable upper and lower displacement values in conventional design are generally not greater than 0.06mm) 。
three Good adhesion “ Anti crack sticker ” It has good bonding force with cement concrete base course and asphalt concrete surface course, and its bonding strength is greater than 4N/mm After being rolled by hot asphalt concrete, the bonding performance is greatly improved rise Therefore, when the horizontal force is applied, it is not easy to slip and destroy.
four Good perforation resistance “ Anti crack sticker ” through 500g Heavy hammer, from 500mm After downward impact 0.3MPa Water pressure of 0.5h Constant pressure, “ Anti crack sticker ” No water seepage.
five Good waterproof and airtightness “ Anti crack sticker ” The self-adhesive coating on the lower surface is greater than 1mm After being pressed by hot asphalt concrete, it is completely combined with cement concrete, greatly improving rise It is waterproof and airtight to prevent surface water from seeping into the cracks of cement concrete plate rise The foundation is stable*** When subjected to the horizontal thrust of the moving vehicle, the covering layer has good self-adhesive and flexibility, which makes it waterproof and airtight.
six Convenient construction “ Anti crack sticker ” The construction method is self-adhesive cold construction. Just remove the release paper ( membrane ) Can be directly pasted on the treated cement concrete base course. The construction is convenient and fast. At the same time, it does not pollute the environment and is an environment-friendly product.
