Abstract

The invention relates to the technical field of polyurethane production and discloses a polyurethane reaction kettle temperature control system, the temperature control system comprises a temperaturesensor arranged on a reaction kettle, an upper computer, a programmable controller, a heating component and a cooling component, the heating component and the cooling component are connected in parallel, wherein the temperature sensor, the programmable controller, the heating component and the cooling component are respectively connected with the upper computer. According to the polyurethane reaction kettle temperature control system provided by the invention, the cooling component and the heating component are arranged and are respectively electrically connected with the temperature sensor, the temperature sensor feeds back the temperature in the reaction kettle in real time, and the cooling component or the heating component are controlled to work according to requirements, so that the temperature of the reaction kettle is always maintained at the required temperature, and the product quality and the production efficiency are ensured. The temperature control system has simple operation, good use effect and easy popularization and use.

Description

technical field [0001] The invention relates to the technical field of polyurethane production, in particular to a polyurethane reactor temperature control system. Background technique [0002] Polyurethane has different temperature requirements at different stages in the production process. It needs to be heated before the reaction, and a large amount of heat will be released during the reaction. The reaction temperature of polyurethane needs to be controlled between 60-100 degrees. If the temperature is too high, it will There will be adverse reactions, affecting the regularity between molecules, affecting the quality and production efficiency of the product, so it is very important to reasonably control the temperature of the reactor. However, the current reactor basically only has a heating device and does not have a cooling device, which seriously affects the heat dissipation effect during the reaction process and makes it difficult to control the reaction temperature. ...
