4, to improve frost resistance of concrete. In concrete added polypropylene fibers, can ease the temperature changes caused by the internal stress of the concrete, preventing cracks extended temperature; at the same time, polypropylene Which is cheaper, to improve concrete impermeability is also beneficial to improve the ability of anti-freeze. PP has a strong alkali resistance, Texas polypropylene, erosion from a variety of basic groups of Hydration products; with good dispersion, polypropylene Which is good, not united, not a bunch, polypropylene prices to ensure that the fibers uniform binder distribution; having high toughness and strength, not easy to play in the mixing bent the ball. ; PVC waterproof material is polyethylene-based raw materials manufacturing, polyethylene non-toxic, it is also non-toxic PVC waterproof material. PVC was poisonous. PP Which is good, waterproof Shouguang Tianxiang (certified), Texas polypropylene supplied by Shouguang City Tianxiang waterproof material plant. Shouguang City Tianxiang waterproof material plant (www.txfscl.com) Shandong Weifang, waterproof, moisture-proof material leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
