What are the key factors that affect the foaming process of the high-pressure foaming machine? As long as the polyurethane component materials (isocyanate component and polyether polyol component), the performance indicators meet the formula requirements. A high-pressure foaming machine can produce uniform and qualified foam products, which are made of polyether polyol and isocyanate in various chemical additives, such as foaming agents, catalysts, emulsifiers, etc.

1. If the pressure of the polyurethane high-pressure foaming machine is too low, the two parts cannot be fully mixed, which will affect the foaming speed, but if it is too high, the entire equipment will require higher technical requirements. The foaming speed also affects the temperature. If the temperature is too high, the reaction speed is fast, which is suitable for other equipment and process requirements; the temperature is too low, the reaction is slow, and the curing time is long, thus affecting the production efficiency. Therefore, in the design process, according to the process requirements, the temperature must be controlled within the corresponding Celsius range.


2. The pressure of the polyurethane high-pressure foaming machine can be set to change the number of pump actions per minute, which has high flexibility; the temperature control is realized by two solid state relays, and the control is adopted, which has the advantages of fast response and good stability.


3. According to the components of the polyurethane foaming machine, the measuring pressure and mixing system can be divided into two categories: low pressure foaming and high pressure foaming. The polyurethane foaming machine is composed of a high-precision metering pump, and each part is delivered to the mixing head separately. After high speed and strong mixing, the liquid is sprayed out evenly to form the desired product.
