热塑性聚氨酯隔膜泵膜片延长产品使用寿命

德国水泵配件厂商Freudenberg Simrit通过不断的改进材料研发出一种新型的热塑性聚氨酯膜片以提升膜片的耐磨性和使用寿命。

聚氨酯材料被认为是市面上容易满足客户实际密封需求的最佳选择，主要是因为该材料有着极强的稳定性和抗腐蚀性。

热塑性聚氨酯膜片比市场上常见的弹性体有着更好的抗撕裂性，同时它还具有高抗拉强度、耐弯曲性和弹性十足的特点。当使用PTFE材质时，隔膜泵可以传输腐蚀性强的介质，甚至是臭氧或者氧化剂。

全新的膜片无论从尺寸上，外形上都合普通的膜片相同。垫片，膜片保护膜，甚至整体的架构和外形都可以满足应用领域耐腐蚀的要求。这种膜片可以安装在真空泵，隔膜泵，隔膜计量泵和蠕动泵系统，接口等上。可应用与空调，热处理，食品卫生行业和建筑行业等等。

隔膜泵一直是业界最全能的水泵，其应用领域也是最为广泛的，作为隔膜泵的易损件—膜片。由于需要长期更换一直受人诟病。耐腐蚀的膜片难以保持较强的弹性，而弹性强的膜片无法传输磨损性强的介质。我公司一直致力于新材料的开发，F48膜片也是我公司近年来新开发的材料，现在德国厂商的新产品似乎给我们带来了一些借鉴的意义。

TPU diaphragms have improved service life

German seals specialist Freudenberg Simrit has developed a new range of diaphragms made of thermoplastic polyurethane (TPU) that are abrasion-resistant and have improved service life.

Polyurethane reportedly makes it possible to adapt sealing materials to meet exact user requirements, due to its molecular blueprint and its controllable chemical synthesis.

The TPU diaphragm material has more tear propagation resistance than conventional elastomers and high tensile strength and elasticity. They also have improved tear propagation properties and flexural fatigue strength. When bonded with PTFE films they can be used in conjunction with very aggressive media, and are resistance to ozone and oxidizing agents.

The shape and geometry of the diaphragm, as well as the fabric inserts, PTFE protective film, inserts, and overall composite structure can be adapted to meet the relevant set of requirements in a given application. The diaphragms are suitable for vacuum pumps, double diaphragm pumps, or diaphragm metering pumps, pneumatic systems, fittings, air conditioning and heating technology, sanitary systems and architectural engineering.

They can also be used in existing pump and component ranges.
