A: high-strength polypropylene fiber properties: high-quality polypropylene high-strength silk from the original polypropylene raw materials combined with a special compound made of low-quality high-strength polypropylene fiber is made of powder and recycled additives patchwork.
2: polypropylene high-strength wire cost: high-strength recycled polypropylene fiber raw materials than the low cost of raw materials 8,000 / ton, additives low price of 120,000 yuan / ton. If it is a small factory production, the cost should be low 1,000 yuan / ton, so the low-cost high-strength polypropylene fiber at least 17,000 yuan less cost / ton.

 Three: polypropylene high-strength wire identification method:
 1. Comparison visual method: high-quality high-strength polypropylene fiber, the length of tidy, uniform thickness, color light Ying-white light. And silk, silk, thick silk, silk, silk, oil silk, knot silk and impurity content is less or no quality; inferior to the contrary.
 
 2. Odor identification method: high-quality polypropylene high-strength wire: environmental protection, tasteless without irritation. Low-quality polypropylene high-strength wire: a pollution, odor heavy irritant.
 
 3. to moisture method: low-quality polypropylene high-strength wire contains moisture, dried and dried by the water to measure, although this price is low, but the inferior fiber is selling water. Assuming low-quality high-strength polypropylene fiber in the water content is 5%, then one kilogram of fiber containing fiber content is only 95%, while the price is 1.05 times the original price.
 
 4. Sunshine method: low-quality polypropylene high-strength wire, usually not subject to ultraviolet radiation test, and high-strength polypropylene fiber in the sunlight one or two years to lose strength, so poor quality polypropylene fiber in the concrete is difficult to play its long-term effect. As long as the site site sampling (to strictly identify the inspection filament and the scene of the site of the short fibers of the same short polypropylene fibers), after a long time of sun exposure, and then detect the tensile strength can be distinguished.
