To develop and produce a satisfactory finished product, the premise is that the material selection must be reasonable and economical. The selection steps include the following main processes:
01.
Analysis of material application issues
This requires research on usage requirements, including functional execution, actual characteristics requirements, and limitations of application conditions.
02.
Analysis of material properties
Transform the application requirements of materials into material characteristics: Since practical problems are often not simple, in addition to some necessary material tests and simulation function execution tests, experience and observation of other conditions have a profound impact on the actual performance of materials. Use is still helpful.
03.
Selection of candidate materials
Selection of candidate materials: Once the required material properties are clearly defined, the remaining selection step is to research the materials that best match those properties. The selection of candidate materials is to first check the material performance data. Of course, it is impossible to investigate thousands of application materials, and there is no need to do so. Based on past experience and simplistic premises, roughly investigate the entire grade of filter materials. So, in practice, choosing a starting point usually only contains a subset of all possible materials. Then, based on the basic purpose requirements, the selection of candidate materials is narrowed down for subsequent detailed evaluation. At the same time, it is important to make sure that all important selection items should be omitted.
If you don’t know how to choose engineering plastics, the following table can be used as a reference.
Comparison of application characteristics of engineering plastics
The smaller the numbers listed in the table are, the better. However, when selecting, you should first determine the most important properties of the parts to be manufactured. For example, if the environment used is very acidic, then PTFE (Fluoron) is not suitable; if you think it is weak in strength, you can also consider PVDF (Steel Fluoron) or use other methods; if the main condition is strength, you should consider POM (Raysteel) vs. NYLON6A (Nylon 6A); however, if size is also important, there is only POM. Therefore, only after the primary conditions are determined can other secondary conditions be compared.
