[0002] Polyether polyols are high molecular polymers, which are usually synthesized by ring-opening polymerization reaction of low molecular weight polyols, polyamines or compounds containing active hydrogen as initiators with alkylene oxides (such as propylene oxide, ethylene oxide, etc.) under the action of catalysts. When polyether polyols are used as raw materials for polyurethane adhesives or foamed plastics, their flexibility and elasticity may be reduced at low temperatures, affecting the use effect. Moreover, at low temperatures, the viscosity of polyether polyols may increase, affecting their fluidity. However, if the polyether polyols are rapidly heated, it may cause thermal decomposition of the polyether polyols, releasing harmful substances, and the thermal decomposition may affect the molecular structure of the polyether polyols, damaging their physical and chemical properties. Therefore, inventing a heating device that can slowly and uniformly heat polyether polyols has become a technical problem that needs to be urgently solved by those skilled in the art.
