PA66沙伯基礎RC-1004防靜電

4 改性尼龍

      由于PA強極性的特點，吸濕性強，尺寸穩定性差，但可以通過改性來改善。 尼龍的改性品種數量繁多，如增強尼龍，單體澆鑄尼龍（MC尼龍），反應注射成型（RIM）尼龍，芳香族尼龍，透明尼龍，高抗沖（超韌）尼龍，電鍍尼龍，導電尼龍，阻燃尼龍，尼龍與其他聚合物共混物和合金等 以下只是部分產品型號，如果你要的型號不在此列，請來電與我咨詢！

The mechanical properties, dimensional stability, heat resistance and aging resistance of glass fiber reinforced nylon (PA) with 30% glass fiber were improved, and the fatigue strength of PA was 2.5 times higher than that of the unreinforced PA. The molding process of glass fiber reinforced PA is similar to that of unreinforced PA, but the injection pressure and injection speed should be increased properly, and the barrel temperature should be increased by 10-40 °C. Because the glass fiber will be oriented along the flow direction in the injection molding process, the mechanical properties and shrinkage will be enhanced in the orientation direction, which will lead to the distortion and warpage of the products. Therefore, the position and shape of the gate should be reasonable in the mold design, the temperature of the mould can be raised in the process. The product is taken out and put into the hot water for its slow cooling. In addition, the greater the proportion of adding glass fiber, the greater the wear of plasticizing components of the injection molding machine, it is best to use bimetal screw, barrel. Flame retardant PA because of the addition of flame retardants in PA, most of the flame retardants in high temperature decomposition, the release of acidic substances, corrosion of metal, therefore, plasticized components (screw, over rubber head, over rubber ring, over rubber gasket, Flange, etc.) to be hard chromium treatment. Process, try to control the barrel temperature can not be too high, injection speed can not be too fast, to avoid too high temperature and decomposition of rubber products caused by discoloration and mechanical properties. Transparent PA has good tensile strength, impact strength, rigidity, wear resistance, chemical resistance, surface hardness and other properties, high transmittance, similar to optical glass, processing temperature is 300l-315 °C, need to strictly control the barrel temperature, melt temperature is too high will lead to degradation of products, low temperature will affect the transparency of products due to poor plasticization. Mold temperature as low as possible, mold temperature will be high because of crystallization and reduce the transparency of products. ·
