Problems solved by technology

[0002] An agitator is a machine with a bladed shaft rotating in a cylinder or tank to mix or knead substances to make them into the desired consistency. Now the agitator is more and more widely used, and many agitators are mostly used for corrosive materials. However, most of them use metal stirring blades to stir in corrosive materials, making them easy to corrode, which affects their use effects and shortens their service life
