X XK2140 PPS
Fiber and monofilament made from PPS can be found in woven or mesh conveyor belts, flame resistant clothing and filtration media. also offers unfilled, high viscosity PPS suitable for extrusion and compression molding to produce slabs, rods and other stock shapes commonly used for prototyping. linear PPS may be used with meltblown and spunbond technologies for melt spun nonwovens.PPS航天用品
在这个技术解决方案的选择材料,日本专家一起在娱乐电子产品的选择与宝理(公司在亚洲的子公司)从泰科纳Vectra液晶聚合物(LCP)和聚苯硫醚(PPS)两种材料。镜头的持有人,另一方面,zui重要的标准是刚性好,重量轻耦合,以排除任何干扰的高频率的共振。
PPS的各个部分,然后从按下的复合材料和制造,焊接在一块形成的zui后一个组件一起反应釜。聚苯硫醚已经有飞机建设使用的所有基本特征 - 抗高温和腐蚀性化学物质,硬度,冲击强度,尺寸稳定性和固有的阻燃阻燃。诀窍是创造合适的结构元素,体现这些属性。这是通过挤压成片的聚苯硫醚,相结合,选择纤维增援,形成高压下的zui后一部分,在300℃(572℉)。
索尼的CD托架插槽,选择玻璃纤维增强聚苯硫醚。从泰科纳easyflowing PPS的高刚性和强度的关键。基于聚苯硫醚复合材料现在被用于许多在飞机制造中的应用,包括机翼的鼻子,副翼和飞机龙骨梁。
与铝相比,使用的聚苯硫醚复合材料提高了设计的自由度,降低了20%至50%的重量和消除腐蚀的可能性。基于纤维增强复合材料泰科纳高性能聚苯硫醚聚苯硫(PPS),作出了重要贡献的空中客车A340和A380飞机的重量减少。这有助于降低油耗和增长幅度和客运能力。
Domestic Water Supply Manifold
Other mouldings in the tap are also made from polymers.The shut-off lever and the connector consist of glass-fibre-reinforced Hostaform GV 1/30 owing to its high strength and rigidity. Finally, the retention clamps, which are subjected to extremely high mechanical loads, are injection moulded from 1140L4 reinforced with 40% glass fibre.In domestic water taps from Atlantic Plastics, a number of materials ensure permanent smooth operation and freedom from leaks.
The slip properties of a Hostaform C 9021 K ball in the valve mechanism ensure long-term smooth operation. The demands made on such components are considerable. For example, the casing must withstand a pressure of 12 bar for 50 years and have correspondingly high creep and fatigue strength.In collaboration with Hoechst Technical Polymers Division, UK, extensive FEM and mould flow studies produced a robust casing made from Hostaform C 2521.
Fuel Cell End Plates
A PEM fuel cell assembly contains a stack of about 200 series-connected cells. The stack is held together through bolting from the end plates to hold the bipolar plates in the stack together and compress the gaskets between them. Intervening insulating plates have bored manifold to feed hydrogen fuel, oxidizing air and cooling water to the stack, as well as to remove the water produced during cell operation. Even with automated machining, the two sets of plates can cost from $300 to $500. ’s development work suggests that integrated injection-molded plates combining end and insulating components may reduce plate cost to between $100 and $120 per stack while also reducing stack weight by at least 10 lb (4.95 kg).
Injection-molded end plates made from ’s polyphenylene sulfide (PPS) can provide significant cost and weight savings in proton exchange membrane (PEM) fuel cells. Design changes integrating the end plate and the adjacent insulating plate may reduce cost and weight as much as 90% compared to current fuel cell prototypes employing metal.
