Description

Technical Field

[0002] In the existing reactor, the agitator has a stirring structure in which the paddles are generally arranged only on one layer of the reactor, and the material is stirred from one direction. For example, the paddles are arranged at the top, bottom or middle of the reactor. The above stirring method is a general device, which is more suitable for medium-viscosity water-based adhesives (viscosity 200-2000mpa.s). When mixing low-viscosity water-based adhesives (viscosity ≤100mpa.s), the low-viscosity fluid rotates with the stirring paddle, and the tumbling effect is poor, resulting in uneven material dispersion and low efficiency, which cannot meet the mixing requirements of low-viscosity adhesives.
