Technical  specifications  of  polypropylene  fibers

Polyacrylonitrile fibers  can  significantly  improve  the  tensile  strength,fatigue strength,and flexural tensile strength of concrete,while  polyacrylonitrile fibers can sig- nificantly improve the early crack resistance performance of concrete.Polyacrylonitrile fibers  can  significantly  improve  adhesion,high-temperature  stability,and  fatigue  dura-  bility  in  asphalt.Moreover,polyacrylonitrile fibers  can  effectively  prevent  the  occur-rence of low-temperature cracking and reflection cracks,effectively improving tensile, shear,compressive,and  impact  strength.
Polyacrylonitrile  fibers  are  widely  distributed  in  mortar,cement  concrete,and asphalt concrete due to their excellent dispersibility and three-dimensional random dis- tribution.They  have outstanding  tensile  strength,melting  and  ignition  points,and  high  comprehensive  performance.

Instructions for Use 

The anti cracking and anti-seepage content of concrete and mortar is 0.91kg/m3,and there are no special requirements for mixing equipment and construction technology.During con-
struction,polyacrylonitrile fibers can bedirectly added to the mixer according to the mix propor- tion.As long as the mixing time is appropriately extended,the anti cracking and anti-seepage
polyacrylonitrile fibers can be fully and evenly dispersed in the concrete and mortar (the content can be increased according to the design drawings and construction requirements).
