    1. Introduction<\/h2>\n

    Polyurethane hard bubble is a material widely used in construction, home appliances, automobiles and other fields, with excellent thermal insulation, sound insulation and mechanical properties. In the production process of polyurethane hard bubbles, the choice of catalyst has a crucial impact on the reaction rate and foam quality. As a highly efficient catalyst, DMDEE (dimorpholine diethyl ether) has been widely used in the production of polyurethane hard foam in recent years. This article will discuss in detail the key role of DMDEE in the production of polyurethane hard foam, especially its improvement in reaction speed and foam quality. <\/p>\n

    2. Basic concepts of polyurethane hard foam<\/h2>\n

    Polyurethane hard bubbles are polymer materials produced by the reaction of isocyanate and polyols. The production process mainly includes the following steps:<\/p>\n

      \n
    1. Raw material mixing<\/strong>: Mix raw materials such as isocyanate, polyol, catalyst, foaming agent, etc. in a certain proportion. <\/li>\n
    2. Reaction foaming<\/strong>: The mixed raw materials react quickly under the action of a catalyst to form polyurethane hard bubbles. <\/li>\n
    3. Currecting and forming<\/strong>: After the reaction is completed, the foam material gradually solidifies to form a final hard bubble product. <\/li>\n<\/ol>\n

      The performance of polyurethane hard foam mainly depends on the selection of raw materials, proportioning and process parameters during the production process. Among them, the choice of catalyst has a direct impact on the reaction rate and foam mass. <\/p>\n

      3. Chemical properties of DMDEE dimorpholine diethyl ether<\/h2>\n

      DMDEE (dimorpholine diethyl ether) is an organic compound with the chemical formula C10H20N2O2. Its molecular structure contains two morpholine rings and one ethyl ether group, which have the following chemical properties:<\/p>\n
