Wide application of glass fiber chopped strands in concrete
July 13,2022
Glass fiber chopped strands have high fiber length accuracy, high fiber amount, consistent monofilament diameter, and the fibers maintain segmental shape before dispersion and have good fluidity. Because they are inorganic, they do not generate static electricity and have high temperature resistance. In the product The tensile force is consistent, which can form a three-dimensional three-dimensional network structure, so that the product has good willfulness and tensile strength, high impact strength, and the glass fiber choppedare dispersed in the same length in each corner of the product, so the tensile strength of the product is consistent. of. And glass fiber fine powder can't do it, because it is a pulverization process, the length of the fiber can not be guaranteed, there are long and short, and there is powder, because it is scrap, which contains many impurities, the diameter of the monofilament is not guaranteed, and the fiber is thick or thin. Therefore, after adding it to the product, the strength cannot be guaranteed, the strength value of each corner is different, and it is easy to stagger and form a group.
Glass fiber chopped strand are obviously made from glass fibers. The development of e glass fibre chopped strands in my country is now growing steadily. my country's glass fiber composite materials show a sustained and rapid growth momentum, but my country's glass fiber is still in a low-cost and inefficient operation. Therefore, in the future, the improvement of the functionality of e glass chopped strands will become a hot spot in the development of the industry. The research report shows that in the next five years, the total consumption of composite materials in the glass fiber market will continue to maintain a strong growth trend with a compound annual growth rate of 63%. After any kind of material meets certain requirements of economic development with its basic performance, it is faced with the requirements of improving performance.
Engineering fiber glass strands concrete can be widely used in the plastering of wall panels, floors, basements, and building exterior walls in housing construction projects; dams, reservoirs, canals, and thin-walled water pipes in water conservancy projects; road and bridge projects. Bridge deck pavement; tunnels; bunkers, air-raid shelters, and protective doors in military engineering; docks, flood control embankments, and concrete prefabricated panels and pipes in port engineering.
Engineered fibers are fibers synthesized from polypropylene and other raw materials. After adding engineering fibers to concrete, the fibers can be easily and quickly dispersed in the concrete to form a disordered support system, which disperses the directional stress of the concrete, prevents the occurrence and development of the original cracks in the concrete, and eliminates or reduces the number and size of the original micro-cracks. It greatly improves the anti-cracking and anti-seepage ability of concrete, improves the toughness of concrete, and prolongs the service life of concrete. In addition, because the fiber itself has a certain strength, the fiber is evenly dispersed in the concrete and forms an anchoring effect, which can absorb a certain amount of damage energy in an instant. Reduce the brittleness of concrete, improve the toughness of concrete, and change the damage characteristics of concrete.
Hebei Yuniufiberglass manufacturers is a professional glass fiber enterprise, established in 2002, with a complete domestic and foreign sales team.
