Product Description
polypropylene crude fiber(PPTF)
Product introduction
Polypropylene crude fiber(PPTF) is a substitute product developed for steel fiber while considering some characteristics of synthetic fiber. Compared with steel fiber, it has attributes with corrosion resistance, easy dispersion and construction, and no damage to mixing equipment. PPTF is made of synthetic resin as the primary raw material, processed through unique technology and surface treatment. It has the advantages of high breaking strength, good dispersion in concrete, and strong gripping force. It can replace steel fiber for cement concrete and overcome the weakness of concrete, such as low tensile strength, low ultimate elongation, and brittleness. In addition, it has properties like tensile resistance, shear resistance, crack resistance, fatigue resistance, and high toughness. The applying fields of PPTF are covered in engineering, such as construction, roads, bridges, and hydraulic engineering.
Packing Regular
Packing is 1.0kg/bag and can also be packed according to the customer's requirements.
Adding PPTF to concrete has the following features
1. Effectively reduce the harm caused by concrete cracks and improve the tensile, bending, and flexural strength of concrete;
2. It can reduce damage while occurring earthquakes and other severe natural disasters;
3. Reduce the fatal defects inside the concrete and improve its impermeability;
4. Protect steel bars from corrosion and improve the durability of concrete structures;
5. Increase the wear resistance of concrete;
6. Significantly improve fatigue resistance;
7. It can prevent damage to tires when used on roads.
Application of PPTF concrete
1. Organic PPTF concrete has high flexural and tensile strength and can use for culvert support, mountain slope protection, and other support projects;
2. Organic PPTF concrete has high crack resistance and can be used in basement anti-seepage, reservoirs, low-pressure water pipelines, and other projects;
3. Organic PPTF concrete has high impact and abrasion resistance and can be used in high-speed water flow parts such as spillways, stilling tanks, and gate floors of water conservancy and hydropower projects;
4. Organic PPTF is made of synthetic materials with the features of steel fiber, so it has more advantages when used in concrete projects in corrosive environments such as seawater;
5. Organic PPTF has high tensile strength, fracture toughness, and fatigue resistance; it can be applied in parts bearing dynamic loads, such as roads, railway bridges, and other projects.
