Fibrillated Microfibers Fibre Pp Polypropylene Mesh Synthetic Fiber

HOT SALE WITH LOW PRICE !Polypropylene mesh fiber is a kind of concrete-strengthening fiber, it become to popular subject in the field of fiber concrete research and application after glass fiber and steel fiber.
Compared with steel fiber, full-dispersed polypropylene fiber has advantages in its thinness, large amount, non-water absorbency, strong acid & alkali resistance and similar elastic modulus with that of concrete.

Polypropylene mesh fiber Properties

With 100% virgin polypropylene as raw material, Polypropylene mesh fiber looks like a net structure with many fiber monofilaments connected. When the fiber was mixed into concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a great number (more than 7million pieces per sqm of polypropylene fibers.

Polypropylene mesh fiber Reinforced Functions to Concrete

It is a kind of concrete-strengthening fiber, it become to popular subject in the field of fiber concrete research and application after glass fiber and steel fiber.

Compared with steel fiber, full-dispersed polypropylene fiber has advantages in its thinness, large amount, non-water absorbency, strong acid & alkali resistance and similar elastic modulus with that of concrete.

Polypropylene mesh fiber The reinforced functions run as follows

              ◆Inrease seepage resistance                                                                     ◆Prolong endurance

               ◆Increase cracking resistance                                                                   ◆Strengthen spurt & fatigue

               ◆Improve tensile, bending & folding strength                                    ◆Increase fire resistance

               ◆Strong acid & alkali resistance and good endurance                    ◆Improve plastic deformity

Polypropylene mesh fiber Relevant suggestion of application

 About length: Generally, the proper length of the fiber added into concrete is 18mm, and in the spray concrete the proper length is     

                               12mm.

 Ratio design: Usual the proper amount of to concrete is 0.9kg/m3, the waterproof layer of the bridge requires 1.20-1.8kg/m3, the 

                              spray concrete in the tunnel is also 1.8kg/m3. the fiber has better effects on the concrete with active compound 

                              materials, such as silicon ash, coal powder, ground slag and zeolite powder etc…

  Mixer adoption: double-axle horizontal compelling mixer is better and self-dropping cylinder mixer can be used too.

 Mixing process: Crushed stones, fibers and sands are put into the mixer in succession, after stirring for about  2-3 minutes, fiber will 

                                  fully spread and then add cement and water and stir again as normal process. The addition of materials also can be 

                                  put into as usual, but the stirring time should be prolonged to more than 4 minutes to make the fiber completely 

                                  dispersed.

Suitable Fields of Polypropylene mesh Fiber

ⅰ. Projects like concrete road, bridge, airport road and basement like factory floor which strictly require cracking

        resistance. The life span of these projects will be more 5-10 years.

ⅱ. The walls of tunnels, mines, roofs and reservoir projects with special construction. When using spray        

        technology in concrete construction, the polypropylene fiber added into the concrete can effectively decrease

        the spray concrete's deformation rate of the walls less than 8% and that of the roof less than 12%, and also can

        reduce the friction. It can improve the constructing efficiency and working environment and popularize the

        spray Technology.

ⅲ. River courses and dams, etc. The polypropylene fiber can improve concrete's resistance to crack and squirt and

       wear to lengthen projects' life span.

ⅳ. Military defense works, dock banks and piers, etc. This fiber can greatly strengthen the concrete's spurt

      resistance and heighten these projects' safety and lengthen their life span.
