monofilament polypropylene fiber, PP monofilament - TZ-PF

TZ - PF polypropylene fibre

TZ - PF polypropylene fiber was developed by our company is dedicated to building project of organic polymer fibers.Polypropylene fiber cross section for the 3 leaf type or circular, high alkali resistance, good chemical stability, excellent in the dispersion of mortar and concrete, grip of strong,Per cubic meter of tens of millions of fiber in three-dimensional random distribution in concrete, the reinforcement of concrete in a purely physical effect.Used in mortar and concrete, can prevent, reduce and delay the early plastic cracking, greatly improve the comprehensive performance of mortar and concrete.Percolating-proof short fiber polypropylene fiber grade pp was used as raw material, after the special craft processing and forming of high strength beam organic fiber monofilament,Its inherent resistance to strong acid, strong alkali, weak thermal conductivity, has extremely stable chemical properties.Add to the mortar or concrete can effectively control of mortar and concrete in the stage of the early plastic shrinkage caused by temperature change factors such as micro cracks,Prevent and suppress the formation and development of crack, greatly improving the crack resistance of concrete permeability resistance, impact resistance and seismic capacity,it Can be widely used in underground waterproof engineering, industrial and civil building engineering of roof, wall, floor, pool, basement, and road and bridge engineering. Mortar and concrete engineering cracking, seepage control, a new type of ideal material wear-resisting.

TZ - PF polypropylene fiber monofilament and mesh divides into two kinds of structure.

The main technical performance, product

1, improve the crack resistance of mortar and concrete. The product increase the limit drawing ratio of mortar and concrete, and through the stress transfer of fiber to prevent slurry, the early concrete curing process caused by the plastic shrinkage and hydration heat crack.

2, improve the permeability resistance of mortar and concrete greatly. The addition of the product reduces the moisture penetration on the surface of mortar and concrete, improve its rigidity water performance.

3, improve mortar, concrete resistance to impact, bending and seismic performance. After joining this product, has improved the toughness of mortar greatly, when fiber concrete hit from the outside world, fiber can absorb a large number of impact energy, reduce the local stress concentration, so as to improve the impact resistance of cement mortar, concrete, improve the flexural and seismic performance.

4, improve wear resistance of mortar and concrete. This product can effectively control the exudation of mortar, concrete mixing materials, reduce the cement particles, sand, such as segregation effect, improve the bonding performance of substrate, forming a stronger surface layer, so as to improve its wear resistance.

5, improve the antifreeze performance of mortar and concrete. after joining mortar and concrete the improvement improved greatly, and improved the concrete freezing-thawing resisting damage ability .

6, strong dispersion, workability.

7, good chemical stability, acid and alkali resistant capability is strong, safe non-toxic, for reinforcement corrosion damage.

8, this product is the physical and chemical performance indexes reached GB/T21120-2007 standard for cement concrete and mortar with synthetic fiber requirements:

Table 1: TZ - PF product Main technical indicators

9, as the secondary reinforcement of concrete material, polypropylene fiber can greatly improve its crack resistance, impermeability, resistance to impact, seismic, antifreeze, anti-abrasion, anti burst resistance, ageing resistance and workability, pumping and water retention.

Attention

1, the range of content: 0.6 ~ 1.2 kg/m3, recommended dosage is 0.9 kg/m3.

2, length: the length of the mortar with monofilament polypropylene fibre is commonly 3 ~ 20 mm; Concrete with monofilament polypropylene fibre length is usually 6 ~ 40 mm. The length of the mortar with reticulate polypropylene fiber is usually 5 ~ 20 mm; With reticulate polypropylene fiber concrete is usually the length of the 15 ~ 60 mm.

3, mixing: don't change the ratio of mortar and concrete, this product can be joined together to stir, appropriately extended mixing time, make its mix.

4, the mixture ratio design, mortar and concrete with polypropylene fiber is secondary to strengthen the role of, is a physical process rather than a chemical process, do not need to change the original mix proportion of concrete and mortar.

5, maintenance: mortar, concrete after joining this product, do not require special maintenance still according to the construction acceptance specifications for curing.

6, polypropylene fiber to replace and cannot be used as structural strengthening material, can only help to strengthen the effect.

7, cannot be used because of the polypropylene fiber and reduce the size of the structure.

8, cannot be used because of the polypropylene fibre and not according to relevant state regulations, carry out the construction and maintenance.

9, high temperature should be careful with polypropylene fiber concrete.

Mainly applicable scope

1, building engineering, mortar, concrete structure of civil and industrial buildings, including site casting, beam-column, the basement floor and side panel, roof cast-in-place floor slab, pool structure, crack resistance, impact resistance, high wear resistance requirements of engineering.

2, municipal engineering, concrete road and square, bridge, tunnel, subway, port terminals, interchange bridge, bridge, airport runway, super long structure, etc.

3, water conservancy project: levees, DAMS, etc.

4, antiknock, refractory engineering: civil air defense, military engineering, oil platform, chimneys, refractory materials, etc.

5, shotcrete, tunnel, culvert lining, thin-walled structure, slope reinforcement, etc.

Packaging and shipping

1, this product is a white loose filamentous, product sales packaging net weight 0.9 kg + 0.05 kg, the plastic bag.

2, the product USES the woven bag packing, each bag 20 small bag, to 18 kg net weight for each bag, can also according to user requirements for packaging. Transport and storage should be light and light discharge, prevent extrusion, as well as to avoid chemical corrosion product or mixed with sharp object.

3, in a ventilated, cool, dry warehouse, avoid exposure and away from the fire, the oil and heat source. Since the date of production, storage period is 18 months.
