Imported nylon board, Dongguan black carbon fiber nylon board, Dongguan plus glass fiber nylon board

Abrasion resistance and dust resistance American University conducted a two-and-a-half-year experiment using BASF nylon carpets and DuPont nylon carpets at international airports. The carpet is under extremely high traffic conditions, and the results show that BASF nylon is slightly better than DuPont in terms of color retention and pile abrasion resistance. There is no difference in the dust resistance of the two yarns.
The mechanical properties of the added glass fiber, dimensional stability, heat resistance and aging resistance are significantly improved, and the wear resistance is times that of the unenhanced ones. The molding process of glass fiber reinforcement is roughly the same as that without reinforcement, but because the flow is worse than before reinforcement, the injection pressure and injection speed should be appropriately increased, and the barrel temperature should be increased by ℃. Since glass fiber will be oriented along the flow direction during the injection molding process, the mechanical properties and shrinkage will be enhanced in the direction of orientation, causing the product to deform and warp. Therefore, when designing the mold, the position and shape of the gate should be reasonable, and the mold process can be improved. temperature, take out the product and put it in hot water to cool slowly. In addition, the greater the proportion of glass fiber added, the greater the wear on the plasticizing components of the injection molding machine. It is best to use a bimetallic screw barrel.
