PA66沙伯基础RC-1004防静电

4 改性尼龙

      由于PA强极性的特点，吸湿性强，尺寸稳定性差，但可以通过改性来改善。 尼龙的改性品种数量繁多，如增强尼龙，单体浇铸尼龙（MC尼龙），反应注射成型（RIM）尼龙，芳香族尼龙，透明尼龙，高抗冲（超韧）尼龙，电镀尼龙，导电尼龙，阻燃尼龙，尼龙与其他聚合物共混物和合金等 以下只是部分产品型号，如果你要的型号不在此列，请来电与我咨询！

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. ·
