Nanofiber filter membrane is widely used in our lives, and it is used in many fields, and it is still expanding. The manufacturing technology of nanofiber filter membranes is more complicated. After the finished product comes out, there will be a polishing process. Polishing can not only eliminate the damage caused by cutting, but also make the nanofiber filter membrane material smoother and brighter. The polishing technology of nanofiber filter membrane can be divided into rough polishing and fine polishing. The following editor will give you a specific introduction.

1, rough polishing. When the nanofiber membrane is roughly polished, a 0 cast iron plate is generally used. When polishing, hold the nanofiber membrane product in your hand and keep it parallel to the grinding surface. At the beginning, the product moves from the center to the side. Do not use excessive pressure. At the end, the product moves from the edge to the center, and the pressure gradually decreases. Rough polishing does not require polishing abrasives, just add water to cool it.

2. Fine polishing. For finishing polishing, polishing paste is used. The polishing nanofiber filter membrane usually uses 2.5μm diamond abrasive paste and 1μm alumina suspension. Spread the abrasive paste or suspension on the fluffy woolen cloth, add an appropriate amount of emulsifier, and polish it on a polishing machine with a rotating speed of 250r/min for about 2 to 3 minutes, until all scratches are removed. After polishing, remember to clean up lubricants and abrasive pastes with water.

In addition to nanofiber membranes, many materials are polished after they are made, such as acrylic and synthetic stones. In the process of product processing, if you are not careful, the product will have a few more scratches, which will affect the appearance. Nowadays, consumers value the appearance of the product very much. Polishing can remove these problems and restore the original smooth side. With the development of science and technology, the polishing technology of nanofiber membranes is now very mature.
