Snakeskin - A novel Polyurethane and PolyCarbonate Honeycomb Composite Material

煤炭、钢铁、采矿、水泥、骨料、生物质、回收、粪肥和化肥、冶炼厂和铸造厂等行业依靠带式输送机来处理材料；然而，粘在带式输送机上的材料的携带对输送机的性能和耐用性有很大影响。这些“逃逸材料”掉落并污染滚筒，增加了清理和维护成本，此外还降低了皮带的有效容量，并由于高冗余负载而增加了能源成本。全行业的解决方案是使用皮带清洁器，主要是浇铸的聚氨酯(PU)刮刀，刮刀的尖端与移动的皮带接触以刮掉它。PU刮刀的材料和机械要求令人惊讶地复杂，因为尖端必须相对柔软才能与皮带表面一致并具有良好的耐磨性；相反，它必须具有足够的机械硬度，以便能够夹紧并紧紧地固定在皮带上而不会偏转。自从上一代刮板刀片被开发出来以来，几乎没有创新，它们可以从各种各样的制造商那里买到。更小的坚硬刀片具有相同的一致性和更好的磨损性能，这意味着可以提高夹紧机构的设计效率，减少维护以及总体成本。铸造PU带式刮刀制造商美国瓦茨乌雷坦产品公司(WUP)针对GB 400M全球带式清洁机市场开发了一种改进的带式刮刀材料。该项目为WUP成为皮带清洗机刀片的技术领先者提供了潜力。“

"Industries such as coal, steel, mining, cement, aggregates, biomass, recycling, manure & fertiliser, smelters & foundries rely on belt conveyors for materials handling; However, carryback of materials that stick to the belt significantly affect the performance and durability of conveyors. These ""fugitive materials"" drop and contaminate rollers increasing clean-up and maintenance costs in addition to reducing the effective capacity of the belt and increasing energy costs due to the high redundant load. The industrywide solution is to use belt cleaners, which are predominantly cast polyurethane (PU) scrapers with the tip held in contact with the moving belt to scrape it.The materials and mechanical requirements of PU scrapers are surprisingly complex as the tip must be relatively soft to conform to the belt surface and have good wear resistance; Conversely, it must have sufficient mechanical stiffness such that it can be clamped and held tightly against the belt without deflecting. There has been little or no innovation since the last generation of scraper blades were developed and they are available from a wide range of manufacturers. A smaller stiffer blade with the same conformability and improved wear properties means that the efficiency of the design of the clamping mechanism can be improved and maintenance is reduced along with overall costs.Watts Urethane Products (WUP), a manufacturer of cast PU belt scrapers, has developed an improved belt scraper material targeting the £400m World market for belt cleaners. This project offers the potential for WUP to become the technology leader in belt cleaner blades."
