The rubber diaphragm is mainly used in valves, regulators, automatic mechanical servo devices, switches and counters for applications such as flow, pressure, differential, liquid level, constant temperature volume thermal compensation, etc. It is widely used. Among them, the common ones we encounter include water pumps, air pumps, etc. There is a very important criterion for evaluating the quality of it, which is whether its service life can meet the design requirements. So, what are the factors that affect the service life of rubber diaphragm products? Do you know? Today, Yongyong Silicone Rubber will join us to discuss this topic together.
Without further ado, let's get straight to the point. The first aspect is the material properties of the rubber diaphragm. This factor has the greatest impact. Often, it is due to this reason that the service life of the product is reduced. For example, the hardness of the material, tensile strength, compression permanent deformation - these are the hard indicators that must meet the requirements of the product drawings. Generally, before mass production, the manufacturer will provide a basic material property table.
Second, the production process varies depending on the application field of the rubber diaphragm. Different production methods are adopted, including pure rubber type; type with nylon fabric in the middle; type with nylon fabric on one side; three-layer composite type of rubber/metal/braided fabric; and some rubber materials also require two-stage vulcanization.
Thirdly, regarding the usage environment, depending on the specific characteristics of the product, there are corresponding requirements for the environment in which the product is used. For instance, there are requirements for the usage temperature and the medium it comes into contact with. It must not exceed the upper limit values of the material's physical properties. Otherwise, it will also affect the product's service life.
Of course, there are many other factors that affect the service life of rubber diaphragm products. The above are just the main three points we have mentioned.
