VI. Production Technology
The production of polypropylene fiber mainly involves melt spinning, stretching, heat setting, and other steps. Through precise spinning equipment and process control, the uniformity, strength, and stability of the fiber are ensured. Additionally, with the continuous advancement of technology, the development of new catalysts and copolymerization techniques has provided more possibilities for the functional modification of polypropylene fiber.
VII. Theory (Underlying Principles)
The mechanism of action of polypropylene fiber is primarily based on its high strength, high modulus, and good adhesion to the substrate. In composite materials such as concrete, polypropylene fiber can effectively disperse stress and prevent crack propagation, thereby enhancing the overall crack resistance and toughness of the material. Furthermore, the addition of fiber can improve the internal structure of the material, enhancing its impermeability and durability.
