High strength polyethylene fiber, and wet and dry strength equal strength polypropylene staple fiber is 2.60-5.30cN / dtex. As the temperature increases 1.5 thick polyethylene fiber, polypropylene intensity decreased; on the contrary the temperature drops, the intensity gradually recover. Elongation at break due to the different varieties of polypropylene in the 15% -35%. External elastic polypropylene polyethylene polypropylene prices in the elongation of 3%, its elastic recovery rate of up to 96%, 10% elongation elastic recovery rate is also about 93%. High polypropylene because strength, flexibility, elongation at break is higher, so good abrasion resistance, particularly resistance to repeated bending of life is high, better than other synthetic fibers. In modern waterproof, the process of construction of more construction of each process is crucial, whether it is ready to pre-construction, or to control the quality of the construction and maintenance of construction after all of this, here a brief introduction to the modern construction of the base surface treatment for introduction. 1. The surface must be flat, solid, clean and free of grease, release agents, dust and other loose animals. 2. For larger holes and cracks should be repaired by patching mortar. 3. panels, require professional slab sealed after construction. 4. screws, bolts recommended to use epoxy or similar material closed. 5. Before using grams of water Fu high elastic waterproof polyethylene fiber pulp, the base surface must be fully wet with water, but not in water. 6. For the porous substrate polyethylene fiber suppliers, especially cement fiberboard, etc., must be done before brushing waterproof slurry, the first for interface treatment.
