The mold temperature of PA6 processing is 80-90 ℃, and the mold temperature has a significant eff on the crystallinity, which in turn affs the mechanical properties of pstic parts. The crystallinity is very important for structural parts, so it is recoended that the mold temperature be 80-90 ℃. For thin-walled and long process parts, higher mold temperature is also recoended. Increasing mold temperature can improve the strength and stiffness of pstic parts, but reduce the toughness. If the wall thickness is greater than 3 , it is recoended to use a low-temperature die with 20-40 ℃. For gss fiber reinforced materials, the mold temperature should be higher than 80 ℃.
Industrial application: polyamide gss fiber reinforced material can be added in the range of 5-60% aording to the product characteristics. This kind of material has good strength, heat resistance, excellent impact resistance, good dimensional stability and low warpage. It is widely used in manucturing bearings, round gears, cams, bevel gears, various rollers, pulleys, pump impellers, n bdes, worm gears, propellers, screws, nuts, gaskets, high-pressure sealing rings, oil resistant sealing gaskets, oil resistant containers, s, hoses, cable sheaths, shearer pulley sleeves, shaper slides, elromagnetic distribution vae seats, cooling equipment, gaskets, shafts It covers all kinds of oil pipes, pistons, ropes and transmission belts on carriers, automobiles and tractors.
PA6首先由德国的BASF联营公司于三十年末期开发出来,四十年初期正式工业化生产。聚酰胺大分子结构中含有大量的酰胺基团,大分子末端为氨基或羧基,是一种强较,能形成氢键且具有一定反应活的半结晶聚合物。
PA6 with gss fiber can improve the mechanical properties, dimensional stability, and the gss fiber content is generally 20%. The addition of wear-resistant filler in a certain range can not only improve the wear resistance of modified nylon 6, but also py the role of reinforcing agent, which has the same eff as gss fiber. This is because nylon 6 is a crystalline polymer, and the crystallinity, the density of crystal nucleus and the growth rate of crystal he great influence on the mechanical properties of nylon 6
