Nanofiber filter membrane is a high-performance material that can be made into a variety of articles and used in many fields. When we make nanofiber filter membrane products, we often do not use it alone, but composite it with resin and other materials, so the choice of resin is also very important. But in actual operation, people tend to ignore this problem, this article editor will talk about the choice of resin.
The resin used to make nanofiber membrane products is epoxy resin. Epoxy resin has four main functions, including curing agent, modifier, filler and diluent. Among them, it is very important as a curing agent. The curing agent is used in bonding, casting, and other steps. A resin with a high epoxy value is strong but also brittle. If the force received is too large and concentrated, it will easily break. Resins with medium epoxy value have moderate strength and are not brittle.
A resin with a low epoxy value will have worse strength, especially at high temperatures. Therefore, when choosing, if the strength requirements are not great, but the resin utilization rate is high, you can use a resin with a low epoxy value; if the strength requirements are high, and you want good permeability, you can use epoxy Higher value resin. For example, a medium epoxy resin can be used as an adhesive, a high epoxy resin is used for casting, and a low epoxy resin is used for coating.
After reading this article, I believe you have a certain understanding of how to choose epoxy resin. In the production process of nanofiber filter membrane products, not only the choice of nanofiber filter membrane monofilament is important, but also the selection of other materials must be carefully considered. Only by doing every step carefully can we produce high-quality products.
