Enhanced polyester fiber
I. Product Introduction
Houde enhanced polyester fiber is made by modifying polyester chips through processes such as blending, spinning, anti-aging treatment, surface oiling treatment, and chopping. It has excellent properties such as high strength modulus, good heat resistance and thermal stability, and good compatibility with asphalt.
When the amount of Houde enhanced polyester fiber added is 0.4% of the mixture, one cubic meter of asphalt mixture will contain hundreds of millions of short fibers, which can significantly improve the tensile, shear, compressive, and impact strength of asphalt concrete, greatly improving the performance and quality of asphalt pavements, and giving asphalt concrete good high-temperature stability, low-temperature crack resistance, fatigue resistance, and water stability. It also has advantages such as strong anti-skid performance and low vehicle noise.
II. Performance Parameters
III. Main Functions and Principles
(1) Reinforcement: Enhanced polyester fibers exist as a three-dimensional dispersed phase in the mixture, randomly distributed and overlapping, forming a network wrapping and constraining effect on the mixture, thus overcoming the relative slip between particles and the generation of cracks.
(2) Dispersion: Without fibers, a large amount of asphalt powder is likely to become colloids, which cannot be uniformly dispersed between aggregates, resulting in oil stains commonly found on pavements. Fibers can disperse colloids.
(3) Adsorption: Due to its large surface area, the fiber material easily adsorbs oil in the asphalt, increasing the viscosity and adhesion of the asphalt, thus increasing the thickness of the structural asphalt film. Analysis shows that the asphalt film is 65%~113% thicker than that of traditional mixtures.
(4) Stabilization: After the addition of enhanced polyester fiber, it can significantly prevent the flow of asphalt and keep the asphalt in a relatively stable state. The fiber has strong holding capacity for asphalt, and excess asphalt will only drip from the surface of the fiber at high temperatures above 130℃. When asphalt expands due to heat in summer, the voids inside the fiber act as a buffer zone, preventing it from becoming free-flowing asphalt and oiling, thus playing a high-temperature stabilization role in the mixture.
(5) Increased Viscosity: Improves bonding strength and increases the adhesion between asphalt and mineral materials. Increases the bonding strength between aggregates through the oil film bonding.
(6) Toughening and Crack Resistance: Enhanced polyester fibers have high modulus and strong elongation deformation capacity, with effective stress distribution and crack resistance functions, which can prevent low-temperature brittle cracking caused by excessive asphalt viscosity in traditional mixtures.
IV. Main Functions
● Improve the quality of asphalt concrete pavements and extend the service life of pavements;
● Prevent reflection cracks and temperature cracks in asphalt concrete pavements;
● Greatly reduce rutting and pavement channeling in asphalt concrete pavements;
● Effectively reduce potholes in asphalt pavements caused by strong pressure and prevent water damage.
V. Main Applications
