Polypropylene mesh fiber
Product Description
PROPERTIES:
With polypropylene as its raw material, this fibre was produced 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).
APPLICATIONS:
As a new type concrete-strengthening fiber, it becomes a new popular subject in the field of fibre concrete research and application after glass fibre and steel fibre.
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 similar elastic modulus with that of concrete. The reinforced functions run as follow:
- Increase seepage resistance
- Prolong endurance
- Improve steel protection
- Increase cracking resistance
- Increase fire resistance
- Strengthen spurt & fatigue
- Improve tensile, bending & folding strength
- Improve plastic deformity
- Strong acid & alkali resistance
