Static mixer is a kind of high-efficiency equipment without power. It makes the material move through the external energy. By fixing the mixing unit in the pipe, the two or more flow fluids can be cut, impacted, rotated and then mixed, so as to achieve good dispersion and full mixing between fluids. The following problems are likely to arise during the use:
1, mixed non-uniform. The main reasons are that the type of mixer is not chosen properly and can not mix evenly; the length of Shanghai static mixer is not enough, and there is not enough mixing time; the mixing medium is too viscous and the fluidity is poor.
2. Static mixer jam. The main reason is that the high viscosity medium can not pass through due to the wrong selection; the mixing medium particles are too large, jammed in the mixing unit; Zhejiang static mixer input pressure is low, poor medium fluidity.

3. Static mixer corrosion. The main reason is that the material selection of pipeline and mixing unit is not correct, and the second reason is that the material of mixing medium corrosive static mixing equipment in Shandong is defective.
