调压节流等功能的实现可以说完全依赖于膜片，而泵阀使用的场景是多变的，不同使用环境对橡胶膜片有着不一样的性能要求，而材料正是决定其基础性能的，今天我们就来谈谈不同材料间性能问题，以供大家参考 Pump valves are widely used in industry, agriculture, and life. The realization of pumping / regulating and throttling functions can be said to depend entirely on the diaphragm. The use of pump valves is variable, and the rubber film is used in different environments. The film has different performance requirements, and the material determines its basic performance. Today we will talk about the performance issues between different materials for your reference.
三元乙丙) ，由于其具有良好的耐臭氧、与耐老化性能，并且成本较低，因此它是橡胶膜片的首选材料，在水泵和气泵中，它有很大的份额占比，为了让三元乙丙具有更多的性能,人们相继对它进行了改良， 比如为了使其具有良好的弹性、耐燃等要求，相继产生了氯化乙丙、磺化乙丙等新型改良品种，因此我们如果听到厂家说用三元乙丙材料做某某产品，也有可能是改良的三元乙丙 EPDM ( Ethylene Propylene Terephthalate ) , because it has good ozone resistance, aging resistance, and low cost, it is the material of choice for rubber diaphragms . It has a large share in water pumps and air pumps. In order to make EPDM have more properties , people have successively improved it. For example, in order to make it have good elasticity and flame resistance, new improved varieties such as chlorinated ethylene propylene and sulfonated ethylene propylene have been produced. , So if we hear the manufacturer say that using EPDM material to make a certain product, it may also be an improved EPDM.
的地方，硅橡胶材料是首选， Then let's talk about silicone rubber. Its biggest feature is that it is non-toxic and tasteless. It can be used in contact with food. Therefore, where rubber diaphragms are needed in food environments such as water dispensers and coffee machines, silicone rubber is the first choice.
℃高温下也能保持一定的回弹和韧性，在欧美国家中，用硅橡胶做的厨具非常受欢迎，也由于它对人体的排异反应非常少，因此在医疗行业中也被广泛使用 In addition, silicone rubber can maintain a certain rebound and toughness at a high temperature of 200 ℃. In Europe and the United States, kitchen utensils made of silicone rubber are very popular, and because it has very few rejection reactions to the human body, it is also used in the medical industry. being widely used
Finally, let's talk briefly about neoprene and nitrile rubber. Neoprene has good acid and alkali resistance and chemical resistance. His application can often be seen in the chemical industry. But the biggest advantage of nitrile is oil resistance. Great advantages when conveying oily materials
，关于橡胶膜片材料的问题简单科普完毕，还有很多橡胶材料，但限于篇幅，今天我们就先不讲了，如果大家还有什么想知道的或业务咨询，可以随时联系我们 Ok , the question about the rubber diaphragm material is simple and popular. There are still many rubber materials, but due to space limitations, we will not talk about it today. If you have any questions or business inquiries, you can contact us at any time.
