Polypropylene Fibre,PP Fibre

Polypropylene Fibre(PP Fibre Mesh Form)
Properties:
With polypropylene as its raw material,this fibre was producted by special technology.The products appear net-like in structure with many fibre monofilaments connected.When the fibre is put into the concrete,the horizontal structure in fibre monofilament can be destroyed in the course of stirring owing to friction and rubbing,and the fibre monofilament or net-like structure will fully stretch,thus the concrete is reinforced by a great number of polypropylene fibres(more than 7 million pieces per sqm).
Application:
1.Reinforced Functions to concrete:compared with steel fibre,full-dispersed polypropylene fibre has advantages in its thinness,large amount,non-water absorbency,strong acid&alkali resistance and similiar elastic modulus with that of concrete.
2.Projects like concrete road,bridge,airport road and factory floor which strictly require cracking resistance.The life span of these projects will be lengthened.
3.The wall of tunners,mines,roofs and reservoir projects with special construction.When using spray technology in concrete construction,the polypropylene fibre added into the concrete can effectively ddecrease the spray concrete's deformation rate of the qalls to less than 8%and that of the roof less than12%,and also can reduce the friction.It can improve the construction effciency and working environment and popularize the spray technology.
4.River courses and dams,etc.The polypropylene fibre can improve concrete's resistance to crack and aquirt and wear to lengthen projects'life span.
5.Military defense works,dock banks and piers,etc.This fibre can greatly strengthen the concrete's spurt resistance and heighten these projects'safety and lengthen life span.
