On the bases of T - 800 carbon fiber ,it added graphene,
reinforcing every aspect of fiber surface performance, it is 8 to
10 times more superior performance than the ordinary carbon fiber .
Poly splendid alkene fiber is widely used in underground
powerhouse, road, bridge, tunnel, high-storey building and other
Get together splendid alkene monofilament fiber are the main
points, mesh, powder, polyester fiber, explosion-proof fiber, etc.
Splendid alkene fiber to concrete, mortar and waterproof thermal
insulation material can be truly enhanced, toughening and crack
resistance and anti-seepage .
Poly splendid alkene fiber is a kind of good acid and alkali
resistance, chemical stability strong polymer materials, has
anti-aging and never degenerating function, it can reduce in
concrete, mortar and back early cracks which caused by shrinkage;
Improve the permeability waterproof ability; Strengthen the
freezing-thawing resisting; Increase the toughness and ductility,
improve durable lasting; Improve the shock resistance, resistance
to deformation and aseismatic ability; Decrease the rate of the
springback of sprayed concrete, increase the thickness of
disposable injection; As a kind of effective temperature
compensating seismic method. Low dosage for 0.8 1 kg/m3 (30-50
yuan/m3) is the best one to save the cost of materials.
The tensile strength is more than 1500 mpa.
Breaking elongation 15-25%.
The elastic modulus of > 3800 mpa.
Fiber evenly dispersed, and silk, winding, no group, use
convenient,can be stired in concrete candirectly.
Polypropylene fiber specification
Polypropylene fiber is modified masterbatch added to pp slices of
blending, spinning, stretching and used for mortar made of fiber
concrete crack seepage control projects. The fiber through special
ultraviolet resistance and anti-static, and processing, make the
fiber dispersed evenly in the concrete, able to realise their
long-term efficacy; The "Y" section to increase the fiber area;
Fiber treated with chemical grafting and physical modification,
rough surface porous, greatly improving the fiber and the adhesion
strength of the cement aggregate. Monofilament polypropylene fiber
in concrete makings, can quickly and easily mixing mortar concrete
materials. Because of superfine fibers, specific surface area is
big, each 1 ㎝ 3 concrete has nearly 20 fiber, so can a disorderly
to support system is formed within the concrete, Can be extremely
effective control of concrete and cement mortar early plastic
shrinkage, drying shrinkage and other non-structural cracks
emergence and development; Effectively prevent aggregate
segregation, hinder the settlement cracks formation. Greatly
improve the impermeability of concrete, shock resistance, increase
the toughness and abrasion resistance of concrete, which greatly
extend the life of a building.

1, improve the crack resistance of mortar and concrete. Experiments
show that compared with ordinary mortar/concrete, such as adding
volume content of 0.1% (about 0.9 Kg / ㎝ 3) monofilament fibers,
mortar/concrete anti-cracking ability increased by 70%.
2, greatly improve the permeability resistance of concrete. 0.9 Kg
/ ㎝ 3 dosage of bunchy monofilament polypropylene fiber concrete is
larger than that of ordinary concrete impermeability capacity
increased by 60% ~ 70%.
3, improve the shock resistance and abrasion resistance of concrete
performance. Polypropylene fiber while low stiffness, load
transferring ability is poor, but it can absorb the impact energy,
reduce the cracks, enhance continuity medium material, reduces the
local stress concentration phenomenon caused by the shock wave is
blocked, thus can greatly improve the shock resistance and
toughness of concrete.
4, improve the antifreeze performance of concrete. Adding
polypropylene fiber in concrete can reduce the effect of internal
stress caused by temperature change of concrete, to prevent
