GH42是一种G/F改性聚丙烯复合材料,通过玻璃纤维填充改性来提高机械刚度和耐热性。它是用汉华公司的特殊加工技术,通过对各种基础PPS(包括HIPP(高等规聚丙烯))进行改性而制成的。其优良的品质使其非常适合用于空调风机和汽车冷却风机,以及需要高刚性和高抗冲击性的产品。 Description G/F modified Compound PP is modified by glass fiber filling and to improve mechanical rigidity and heat-resistance. It is produced made by modifying . A variety of base PPs, including HIPP (High Isotactic Polypropylene), with Hanwha Total's special processing technology. Its excellent quality makes it ideal for use in air conditioner fans and automobile cooling fans; and like products requiring high rigidity and high impact-resistance. Characteristics There is a wide selection of Hanwha G/F PP products available for uses in products that require high- and ultra-high rigidity and high flowability. Adjustments depending upon molding conditions present no difficulty. Several Hanwha Total G/F PPs have improved dimensional stability thanks to blends with mica, and fire-resistance ratings of UL94 V-0. Applications G/F PP helps improve rigidity and impact-resistance simultaneously dimensional stability, while providing heightened heat-resistance. These grades are high-temperature strengths with added. The most common uses are in: Automobile parts, including brackets, switch boxes, cooling fans and oil caps; Electric and electronic parts, such as air conditioner fans, washing machine drums, pulley/legs for washing machines, and more; Household/industrial appliances, parts for electric tools, showers, bidets , etc. |

模具没做好,成果都在这十条
2016-10-20 模具制造过程是是一个复杂的过程,从设计、加工、装配、调试等步骤,最后才能真正的投入使用,在整个生命周期中,影响模具质量的因素主要有以下十个方面: 1.模具钢材 几种常用的钢材 钢材是模具质量的决定性因素,选择合理的钢材是重中之重。选择钢材的标准是: ①注塑材料的要求―不同的塑料要选用不同的钢材,如对高抛光的要求、耐腐蚀的要求等等; ②价格―钢材性能够用就好,不是越贵越好;考虑到模具的成本因素,模具钢材要选用和模 |
