Polyol Polyurethane Production Line

August 16, 2024
           
What Is Polyol Polyurethane?
Polyol polyurethane refers to a type of polymer material produced by the reaction of polyols and isocyanates, which is widely used in the manufacture of polyurethane foams, elastomers, coatings, adhesives and sealants. Polyol polyurethane is a polymer material with a wide range of uses and excellent performance. By adjusting the type and ratio of raw materials, it can meet the needs of various fields and is widely used in modern industry.
Polyol Polyurethane Production Line Equipment Configuration
  • 1. Heating Reactor with Steam Heater

  • The core part of this equipment is the reactor, which is used to carry out the reaction of polyester polyol production. Reactor is usually equipped with a steam heater, which can provide uniform heating and temperature control through steam to ensure the successful progress of the reaction process.

  • 2. Steam-controlled Plate Separator

  • Separation and purification are required in the production process of polyester polyols. This process usually uses a steam-controlled plate separator. This equipment can separate the reactants to ensure pure products.

  • 3. Continuous Stirred Tank Reactor (CSTR)

  • CSTR is usually used for mass production of polyester polyols. Its advantage is that it can achieve continuous production, save time and labor costs, and improve production efficiency.

  • Q
    Production Principle of Polyol Polyurethane
    The production principle of polyester polyol is basically achieved through polyesterification reaction. The polyesterification reaction is obtained by reacting compounds containing carboxyl and hydroxyl groups under certain conditions, and the reaction conditions often include certain parameters such as temperature and pressure. In the reaction, water and ester compounds are produced. Through proper distillation and filtration, pure polyester polyol can be obtained.
  • Q
    Application Scope of Polyol Polyurethane
    Polyester polyol is widely used in coatings, resins, plastics, fibers and other fields. One of the most important application fields is the production of polyurethane foam. Polyester polyol has good performance and processing performance. In the production of polyurethane foam, polyester polyol as the main raw material can make the foam have better insulation and mechanical properties, and is an irreplaceable important material.
