Description

technical field

The utility model relates to the field of chemical equipment, in particular to a discrete ester-soluble polyurethane adhesive production reaction kettle.

Background technique

The reaction kettle is a common and necessary equipment for the production of chemical products. The stirring mechanism of the reaction kettle is a device for forced convection and uniform mixing of liquid and gas media. The type, size and rotational speed of the stirring mechanism have an effect on the distribution of stirring power between bulk flow and turbulent flow fluctuations. Generally speaking, the power distribution of the turbine-type stirring mechanism is beneficial to turbulent flow fluctuations, while the propeller-type stirring mechanism is beneficial to the overall flow. For the same type of stirring mechanism, under the condition of the same power consumption, the large-diameter, low-speed stirring mechanism consumes power mainly in the overall flow, which is conducive to macroscopic mixing. Small-diameter, high-speed stirring mechanism, the power is mainly consumed in turbulent pulsation, which is conducive to micro-mixing. The enlargement of the stirring mechanism is related to the process.

In the production process of high-performance ester-soluble polyurethane adhesive, it is necessary to comprehensively consider the production efficiency and the utilization rate of the reactor. At the same time, the reaction efficiency must be considered to ensure the quality of the product. In the production process of high-performance ester-soluble polyurethane adhesive, sufficient stirring is required. At present, the stirring effect is mainly improved by increasing the stirring speed, but at a higher stirring speed, the volume of the feed liquid expands, which affects the charging capacity of the reactor and affects the production efficiency; moreover, the high-performance ester-soluble polyurethane adhesive is very difficult to It is easy to produce dense viscous bubbles. If these clustered bubbles are not eliminated in time, it will have a great impact on the pass rate of later products. The traditional reactors have insufficient measures in this regard and need to be improved urgently.
